Attic Insulation in Arlington - Same-Day Service, Done Right the First Time

Insulation in Arlington, TX

Crawl space encapsulation and vapor barriers are rare in Arlington, because most homes here sit on concrete slabs. What Arlington homeowners actually need most is attic insulation work, specifically blown-in fiberglass or cellulose and air sealing, in the single-story brick-veneer ranch homes built between 1958 and 1990. Those houses carry R-11 or less in the attic, and the July heat turns that space into a 150°F oven that works against your air conditioner for about seven months a year.

Why Arlington Homes Are Different

Arlington’s housing stock developed fast from the late 1950s through the 1980s, driven by Six Flags, the Rangers, and the Cowboys stadium corridor. The result is block after block of nearly identical slab-on-grade brick-veneer ranches, and those homes are now between 40 and 60 years old, all hitting the same degradation window at once. The defining problem here is flex ductwork laid directly on the attic floor with little to no insulation wrap, running through unconditioned attic space. Even after a fresh R-49 blown-in job, those ducts leak conditioned air into the attic before it ever reaches a bedroom. Any honest insulation company working in Arlington has to address duct sealing and encapsulation as part of an attic insulation job, not as a separate upsell. The other reality is Climate Zone 3A heat: seven months of cooling demand, attic temperatures that routinely exceed 150°F, and winter ice storms that push a secondary spike of demand for wall and attic work. Fort Worth has older mixed stock and Grand Prairie has newer construction, but Arlington’s central and east-side tracts from the 1960s and 1970s are the ones where the flex-duct problem is most acute.

Our Main Arlington Services

Most homeowners in Arlington call us about two things: attic insulation that has settled or was never sufficient, and energy bills that keep climbing in a house that should be cheap to cool. Here is a quick look at the service our Arlington customers ask for most.

Attic Insulation in Arlington

Most Arlington ranch homes were built with R-11 fiberglass batts or less, and Code now requires R-38 to R-60 for Climate Zone 3A. The batts have settled, gaps have opened around can lights and ceiling penetrations, and the seven month cooling season makes the attic the single largest source of heat gain in the house. We remove the old material when needed, air seal the floor, and blow fresh insulation to the depth that actually works, not the depth that just looks full.

Crawl Space Encapsulation & Vapor Barrier in Arlington

Crawl spaces in Arlington are uncommon, but they do exist in a small number of pier-and-beam homes scattered across older north-side and downtown-adjacent streets. When they exist, the Climate Zone 3A humidity and occasional winter ice storms create damp, musty conditions that push moisture into floor framing and living spaces. Most slab homes here never see this problem, but for the ones that do, the work involves lining the floor and walls with a reinforced vapor barrier, sealing vents, and controlling moisture at the source. We handle the full Crawl Space Encapsulation & Vapor Barrier job, from cleanout to encapsulation.

Crawl Space Vapor Barrier

Signs you need it

You smell mildew in the house, see condensation on floor joists, or spot standing water in the crawl space after heavy rain. Hardwood floors upstairs can cup or buckle.

What it costs in Arlington

Most Arlington vapor barrier installations run between $1,800 and $5,500 depending on square footage, access, and how much old material needs to come out first.

How we do it

We remove any debris and old poly first, then roll out a 10 to 20 mil reinforced barrier, run it up the foundation walls, and seal every seam and penetration with tape and mastic. We finish by taping the barrier to piers and installing any needed access door sealing.

Crawl Space Encapsulation

Signs you need it

Insects and rodents find their way in, the humidity makes the house smell, or you have ductwork running through the crawl space that sweats in summer. Family members with allergies often notice first.

What it costs in Arlington

Full encapsulation in Arlington runs from $4,000 to $9,000 for a standard pier-and-beam home, including the vapor barrier, sealed foundation vents, and a dehumidifier rough-in if needed.

How we do it

We seal the floor and walls, close off foundation vents, and install a dedicated dehumidifier when the space calls for it. The goal is a dry, clean space that stops moving moisture into the conditioned part of the house.

Crawl Space Moisture Control

Signs you need it

You notice rust on HVAC registers in the floor, a lingering damp smell when the AC cycles, or visible mold staining on the subfloor under the house.

What it costs in Arlington

Moisture control work in Arlington, including sealing a small damp area and adding a vapor barrier, starts around $1,200 and goes up to $4,000 depending on how far the moisture has spread.

How we do it

We find the water entry point first: a leaky pipe, unsealed vent, or poor grading outside. Then we dry the space, repair the barrier, and add ventilation or a dehumidifier if the humidity will not stay down.

What Crawl Space Encapsulation & Vapor Barrier Costs in Arlington

Does encapsulation help with humidity problems in Arlington pier-and-beam homes?

Yes. Sealing the floor and walls stops most of the moisture that migrates up from the soil, and closing foundation vents keeps the humid outside air from cycling through. A dehumidifier finishes the job when the space will not stay below 60% relative humidity on its own.

How long does crawl space encapsulation take in Arlington?

Most full encapsulations finish in one to two days. Larger homes or spaces with serious debris, plumbing leaks, or rodent damage can take three days. We give you a clear schedule before we start, and we do not leave a job until the barrier is clean and sealed.

Spray Foam Insulation in Arlington

Spray foam in Arlington is most valuable at the roofline, where it turns the attic into a semi-conditioned space and keeps the 150°F summer air off your ductwork. For the thousands of single-story brick-veneer ranches with flex ducts running across the attic floor, closed-cell foam at the roof deck is the single most effective fix for hot attics and leaky, hot air delivery. We are experienced with Spray Foam Insulation on exactly this housing type.

Closed-Cell Spray Foam

Signs you need it

Your attic is over 130°F even when the AC runs, your upstairs rooms can’t hold temperature, or you want to use the attic for storage without ruining stored items.

What it costs in Arlington

Closed-cell foam at the roofline in Arlington runs $2.50 to $4.50 per board foot installed, with most full ranch-house roof decks falling between $6,500 and $13,000.

How we do it

We first verify the roof has no active leaks, then spray a continuous two to three inch layer against the roof deck, closing off gable and soffit vents as required. The result is an attic that stays within 10 to 15 degrees of the house temperature.

Open-Cell Spray Foam

Signs you need it

You need an air seal and sound dampening but don’t want the higher cost of closed-cell, and your attic is not used for storage.

What it costs in Arlington

Open-cell foam in Arlington runs $1.00 to $1.80 per board foot, so a typical ranch attic roofline lands between $4,000 and $8,500.

How we do it

We spray a thick, air-sealing layer across the roof deck and let it expand to fill gaps around framing. Open-cell does not stop water, so roof leaks have to be addressed first, but it does an excellent job of air sealing and sound control.

What Spray Foam Insulation Costs in Arlington

Will spray foam in an Arlington attic help with a hot house?

Yes, more than any other single attic change. Sealing the roofline keeps the 150°F outside air from ever entering the attic, so your ductwork and ceiling don’t sit in an oven. Most customers see their upstairs rooms hold temperature much better the first summer.

Is spray foam worth the cost in Arlington?

If your ducts run through the attic, yes. The flex-duct problem in Arlington’s ranch homes means the attic air temperature directly affects your conditioned air before it reaches rooms. Foam at the roofline fixes that at the source, and the cooling savings compound across seven months of summer.

Blown-In Insulation in Arlington

Most Arlington ranch homes were built with R-11 fiberglass batts in the attic, and those batts are now compressed, dusty, and nowhere near the R-38 to R-60 the Climate Zone 3A cooling load demands. Blown-in insulation is the fastest, most affordable way to bring that attic up to current code and knock down a seven month cooling bill. We install Blown-In Insulation using Owens Corning and Johns Manville fiberglass, or GreenFiber cellulose when a denser, air-sealing fill makes more sense.

Blown-In Fiberglass

Signs you need it

Your attic has original batts that look flat, dusty, or uneven, or you can see bare spots around the attic entry. Rooms stay hot even with the AC running.

What it costs in Arlington

Blown-in fiberglass in Arlington runs $2,500 to $6,500 for a typical 1,800 to 2,400 square foot ranch attic, depending on depth and whether the old material stays in place.

How we do it

We run a hose into the attic and blow a consistent, fluffed layer to the target R-value, leveling it across the entire floor. We use depth markers so you can verify coverage, and we never blow over a leaky, unsealed floor without addressing it first.

Blown-In Cellulose

Signs you need it

You want better air sealing than fiberglass alone, you have old loose fill that has settled, or you want a recycled, denser product that resists air movement.

What it costs in Arlington

Blown-in cellulose in Arlington runs $2,800 to $7,000 for the same size attic, slightly higher than fiberglass because of the material density and installation time.

How we do it

We use GreenFiber cellulose, blown to a dense, even layer that fills gaps and slows air movement better than loose fiberglass. It goes on top of the old insulation when the old material is dry and uncontaminated.

What Blown-In Insulation Costs in Arlington

How much blown-in insulation do Arlington homes need?

For Climate Zone 3A, current code calls for R-38 to R-60 in the attic. An Arlington home built in the 1970s with original batts is likely sitting at R-11 or less, so the top-up depth is substantial, usually 12 to 18 inches of additional material.

Can you blow insulation in without moving my stuff out of the attic?

If the attic is used for storage, we work around stored items as much as possible, but the floor needs to be accessible for full coverage. We can clear a path or work in sections, and we keep the hose and equipment off your finished areas inside the house.

Radiant Barrier Installation in Arlington

Radiant barriers in Arlington make sense because of what the attic faces every summer: seven months of direct, constant heat forcing the roof deck surface above 150°F. A radiant barrier reflects a large portion of that heat back out instead of letting it radiate into the insulation and the living space below. We install Radiant Barrier Installation as a foil layer stapled to the underside of the rafters or as a foil-faced decking on new construction.

Attic Radiant Barrier

Signs you need it

Your attic is unbearably hot even on mild days, your AC runs constantly in the afternoon, or the ceiling below the attic feels warm to the touch.

What it costs in Arlington

A radiant barrier installed on the underside of rafters in a typical Arlington ranch attic runs $1,800 to $4,500 depending on roof shape and access.

How we do it

We staple a perforated foil layer to the bottom of the roof rafters, working from the ridge down to the eaves. The perforation prevents moisture trapping, and we leave the foil slightly loose so it can reflect heat effectively.

Radiant Barrier Roof Deck

Signs you need it

You are replacing a roof or building an addition and want the barrier built into the decking itself, not retrofitted underneath.

What it costs in Arlington

Foil-faced roof decking adds $2,500 to $6,000 to a typical Arlington roof replacement, depending on the roof area and the decking product selected.

How we do it

We coordinate with the roofer to install foil-faced OSB or plywood as the decking goes down, which bonds the reflective surface directly to the underside of the roof. The result is a barrier that lasts as long as the roof itself.

What Radiant Barrier Installation Costs in Arlington

Does a radiant barrier work in Arlington’s hot climate?

Yes. Radiant barriers are most effective in cooling-dominated climates like Arlington’s, where the roof absorbs direct sun for long stretches. The barrier reflects radiant heat before it reaches your insulation, lowering attic temperatures by 20 to 30 degrees in peak summer.

Can I install a radiant barrier if I already have enough insulation?

Yes. A radiant barrier is independent of the insulation R-value. Even with R-38 or R-49 on the floor, the barrier reduces the heat load the insulation absorbs, which makes the insulation itself more effective at slowing heat transfer into the house.

Insulation Removal & Replacement in Arlington

Arlington homes built from the late 1950s through the 1980s often have original insulation that is now contaminated with rodent droppings, dust, and decades of air leakage debris, or has settled to a fraction of its original depth. Removal and replacement is the right call when the old material can’t be topped up safely, and in Arlington’s ranch-heavy stock, that call comes more often than in newer cities. We handle Insulation Removal & Replacement as a full-service job: vacuum out, sanitize, air seal if needed, and blow in fresh material.

Attic Insulation Removal

Signs you need it

The existing insulation is wet, moldy, infested, or compressed into a hard mat. You see signs of rodents or water stains on the attic floor.

What it costs in Arlington

Attic insulation removal in Arlington runs $2,000 to $4,500 for a standard ranch home, depending on attic size, access, and how much material needs to be bagged out.

How we do it

We run a high-powered vacuum hose into the attic and remove everything down to the deck, bagging it inside sealed trash systems, not blowing it into your yard. The clean deck gives us a fresh surface to inspect and air seal before new insulation goes in.

Contaminated Insulation Removal

Signs you need it

You find rodent droppings, old bird nests, or mildew in the attic, or a family member’s allergies got worse since the insulation was disturbed.

What it costs in Arlington

Contaminated insulation removal in Arlington starts at $2,500 and can reach $6,000 when the contamination is extensive, the attic is large, or sanitizing and deodorizing are required before re-insulating.

How we do it

We seal the attic access while vacuuming to keep dust out of the house, remove every bit of the contaminated material, then fog or treat the space as needed. After the deck is clean, we blow in fresh insulation.

What Insulation Removal & Replacement Costs in Arlington

How do I know if my Arlington attic insulation needs full removal or just top-up?

If the material is dry, uncompressed, and free of rodents or mold, a top-up works. If it has visible contamination, water damage, or has compressed to a thin mat, full removal is usually the right call. We’ll tell you which one you need before we quote anything.

Does removing old insulation in Arlington require a permit?

Generally, no. Insulation removal and replacement is a repair activity, not a structural change, so Arlington does not require a permit for this work in a standard single-family home. If your work includes duct changes or roof decking, that’s a different conversation, and we’ll flag it for you.

Attic Air Sealing in Arlington

Attic air sealing is the hidden first step in almost every Arlington insulation job, because the 1960s and 1970s ranch homes here were built with zero sealing at top plates, can lights, and duct boots. Air leaks in from the living space, carries moisture and heat up into the attic, and undermines whatever insulation sits on the floor. We do Attic Air Sealing before any blown-in job, because sealing first and filling after is the only sequence that actually works.

Attic Floor Air Sealing

Signs you need it

You feel drafts in rooms below the attic, see dust trails on insulation, or notice that the house gets dusty fast after the attic is disturbed.

What it costs in Arlington

Attic floor air sealing in Arlington runs $1,200 to $3,500 for a typical ranch house, depending on how many penetrations need foam, caulk, and mastic.

How we do it

We push back the insulation in sections, seal every top plate, wire penetration, and plumbing vent with foam, caulk, or mastic, then pull the insulation back over the sealed area. The work is methodical, not a spray-and-hope pass.

Can Light & Duct Boot Sealing

Signs you need it

You can feel air moving around your recessed lights, or you notice dust streaks on your ceiling around the light fixtures. Duct boots feel loose when you push on them from inside the attic.

What it costs in Arlington

Sealing can lights and duct boots in Arlington typically runs $500 to $1,800 depending on the number of fixtures and boots, and whether any duct reconnect work is needed.

How we do it

We use rated can light covers or seal around the fixture with a fire-safe caulk or foam, then seal the gap between the duct boot and the drywall. This stops a surprising amount of conditioned air loss in Arlington homes.

What Attic Air Sealing Costs in Arlington

Why is air sealing more important in Arlington than in colder Texas cities?

Because Arlington’s cooling season runs about seven months, any attic leak is pulling conditioned air out of the house continuously across the hottest part of the year. In colder climates, leaks cost you a few months of heating; here, they cost you the entire summer.

How long does attic air sealing take in an Arlington ranch home?

Most single-story Arlington ranch homes take one full day for a complete floor sealing, including moving the insulation and re-laying it. Larger homes or those with many can lights and duct boots may run into a second day.

Wall Insulation in Arlington

Wall insulation in Arlington is a different job than attic work, because most of the city’s brick-veneer ranch homes have either zero wall cavity insulation or a thin, compressed layer that does almost nothing. The brick outer wall soaks up sun all afternoon, and the interior drywall sits directly against that heat load. For these homes, injection foam or drill-and-fill is the only way to add wall insulation without gutting the interior. We do Wall Insulation with a clean process that leaves your brick and drywall intact.

Injection Foam Wall Insulation

Signs you need it

Your exterior walls feel warm from inside during summer, you hear outside noise more than you’d expect, or your energy bills stay high even after the attic is brought up to code.

What it costs in Arlington

Injection foam wall insulation in Arlington runs $4,000 to $9,500 for a typical single-story brick ranch, depending on wall area, number of penetrations, and access.

How we do it

We drill small holes through the mortar joints or interior drywall, inject a slow-rise foam that fills the cavity completely, then patch the holes to match. The process takes one to two days, and the difference in wall temperature is immediate.

Drill & Fill Wall Insulation

Signs you need it

Your home is brick-veneer with empty or partial wall cavities, and you prefer a dense-pack fill rather than foam injection.

What it costs in Arlington

Drill-and-fill with dense-packed cellulose or fiberglass in Arlington runs $3,500 to $8,000 for a typical ranch house.

How we do it

We drill either from the exterior through mortar joints or from the interior through drywall, blow in dense-pack material until the cavity is full, then patch the holes cleanly. On brick, we match the mortar color as closely as possible.

What Wall Insulation Costs in Arlington

Can wall insulation be added to a brick Arlington home without tearing up the walls?

Yes. Drill-and-fill or injection foam goes through small holes drilled in the mortar joints or drywall, and the holes are patched afterward. The brick exterior stays intact, and the interior is patched and repainted if that was the access point.

Will wall insulation help with outside noise in Arlington?

It helps, but it is not a soundproofing cure by itself. Dense-pack cellulose and injection foam both fill the cavity and reduce sound transmission meaningfully, especially for brick homes where the wall air gap was working like a drum. Interior wall soundproofing is a separate, more specific treatment.

Attic Cleaning & Rodent Proofing in Arlington

Rodent activity in Arlington attics is a year-round problem, made worse by the many mature neighborhoods with older homes and large trees close to the roofline. Squirrels and roof rats find their way in through gable vents and gaps around eaves, and once inside, they tear up insulation, chew wires, and leave droppings throughout. We do Attic Cleaning & Rodent Proofing as one job: remove the contamination, sanitize, and close the entry points so they can’t come back.

Attic Cleanout

Signs you need it

You hear scratching above the ceiling, see droppings or nesting material in the attic, or smell a musty, ammonia-like odor around the attic access.

What it costs in Arlington

An attic cleanout in Arlington runs $1,500 to $3,500 depending on attic size, the amount of contaminated material, and how much needs to be vacuumed out.

How we do it

We remove all contaminated insulation, bag it, and vacuum the deck clean. Then we fog or treat the space to knock down odor and bacteria before any new insulation or sealing work.

Rodent Proofing & Exclusion

Signs you need it

You have active rodent entry points around gable vents, soffits, or where pipes and wires enter the attic. You see fresh droppings or hear movement at dawn and dusk.

What it costs in Arlington

Rodent proofing and exclusion in Arlington runs $800 to $2,500 depending on how many entry points need sealing, the roofline height, and whether any vent replacement is needed.

How we do it

We find every opening, seal the gaps with steel wool, hardware cloth, and sealant that rats can’t chew through, and replace damaged vents. The finishing step is a full check of the roofline from top to bottom.

What Attic Cleaning & Rodent Proofing Costs in Arlington

What rodents get into Arlington attics most often?

Roof rats and squirrels are the most common, with mice less frequent in Arlington than in more rural areas. The rat problem is worse in older neighborhoods with mature trees and older gable vents that were never sealed properly.

Do I need to leave the attic clean before you can insulate?

No. We do the cleanout as part of the job, and we’ll let you know if the contamination is serious enough to require full removal and sanitation before new insulation goes in. The goal is a clean surface and a sealed attic before we add new material.

Home Energy Audit in Arlington

A home energy audit in Arlington makes sense before any big insulation spend, because the ranch houses here hide losses in so many places: unsealed top plates, leaky flex ducts, old can lights, and compressor units that are working against the attic heat. The audit tells you exactly where the conditioned air is leaving and where your money should go first. We perform Home Energy Audit work using real measurements, not a guess from the street.

Blower Door Test

Signs you need it

Your house is hard to keep comfortable, drafts show up in odd places, and you want a hard number for how leaky the building envelope really is.

What it costs in Arlington

A blower door test in Arlington is included in a full home energy audit, which runs $350 to $700 depending on home size and the number of systems tested.

How we do it

We mount a calibrated fan in an exterior door frame and depressurize the house to measure total air leakage. The number tells us in minutes how much air is escaping, and where the biggest leaks are relative to the house size.

Thermal Imaging Inspection

Signs you need it

You notice hot or cold spots in different rooms, or you want visual proof of where insulation is missing before committing to a repair.

What it costs in Arlington

A thermal imaging inspection in Arlington is typically included with a home energy audit, or $200 to $400 as a standalone service depending on the size of the house.

How we do it

We walk the interior with an infrared camera while the house is under pressure, looking for temperature differences that show missing insulation, air leaks, and duct leaks. The images give us a map to fix the biggest losses first.

What Home Energy Audit Costs in Arlington

Will an energy audit in Arlington tell me what to fix first?

Yes. The audit includes blower door, thermal imaging, and a walkthrough of the attic, walls, and ductwork. We hand you a written list of what is wrong, what it costs, and which fixes give the fastest payback for Arlington’s cooling-heavy climate.

How long does a home energy audit take in Arlington?

Most full audits run two to three hours in a standard ranch home. The blower door test itself takes about 30 minutes, and the thermal imaging and duct checks fill out the rest. We schedule at a time that works for you, including weekends.

Brands We Service in Arlington

We install and service insulation from Demilec, Owens Corning, Johns Manville, and GreenFiber in Arlington. We stock the most common products locally so we’re not waiting on a warehouse before we can start. See our brands for more detail.

Pricing for Insulation in Arlington, TX

FAQs About Insulation in Arlington, TX

How quickly can we schedule insulation work in Arlington?

Most Arlington jobs get scheduled within a week or two of the estimate. Because summer attic temperatures here routinely exceed 150°F, we try to prioritize air sealing and duct-related requests during the hottest stretch of the year.

Do we need a permit for insulation work in Arlington?

Routine attic insulation and air sealing typically doesn’t require a separate permit. Many Arlington homes have flex ductwork running through the attic with little insulation wrap, so we check duct condition as part of the inspection rather than assuming it only needs a standard blown-in top-up.

How does the written estimate work?

We inspect the attic, including the condition of any ductwork running through it, and measure existing insulation depth. From there we write up a price broken out by task, so you know the full cost for your Arlington home before work begins.

Which areas do you serve besides Arlington?

We also work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If you’re in one of those areas, or just outside Arlington, reach out and we’ll confirm scheduling.

What happens to the old insulation removed from an Arlington attic?

We bag it and haul it away as part of the job, whether it’s original brick-ranch attic batts or material disturbed around leaking ductwork. If we find duct leaks during removal, we’ll flag them before closing the attic back up.
