Why Walt’s Insulation Is Irving’s Preferred Attic Insulation Company
We’re the one down the road, not a franchise operation working out of a call center three states away. Walt Brenner founded this company in 2000, and we’ve been crawling through North Texas attics ever since. When you call Walt’s Insulation about Attic Insulation, you talk to a live person, 24/7. Not a voicemail. Not an answering service. A person who can actually answer questions about R-values, air sealing, and why your upstairs runs ten degrees hotter than your living room.
Every technician who shows up at an Irving home is background-checked and uniformed, so you know exactly who’s walking through your door. Our work carries the Done Right Promise: if it’s not done right, we make it right. No runaround, no “that’s not covered,” no disappearing after the check clears. That guarantee is lifetime, and it applies to every attic we touch in Irving.

Our Attic Insulation Services in Irving
Blown-In Attic Insulation
Blown-in fiberglass remains the go-to for most Irving attics. We install Owens Corning AttiCat and GreenFiber cellulose, and we can hit R-38 or R-49 in a single afternoon. For the 1960s-1980s tract homes that dominate Irving’s residential core, blown-in insulation fills the gaps and settles evenly across existing joists, which batt insulation simply cannot do as effectively.

Attic Batt Insulation
Batt insulation works well for Irving homes with open, accessible attic floors and consistent joist spacing, particularly in newer construction where the framing is still uniform. We install CertainTeed and Johns Manville batts, cut precisely to fit around can lights, duct runs, and attic access hatches. In Irving’s summer heat, batts hold their R-value well when air-sealed underneath, but they fail quickly if gaps are left around penetrations.

Attic Insulation Top-Up
This is the service we recommend most often for Valley Ranch and other 1980s-era Irving neighborhoods. Original blown fiberglass has settled to a compressed layer that often measures under R-20, which is nowhere near the R-38 Texas energy code expects. We blow fresh insulation directly over the settled material after air-sealing the attic floor. A top-up in Irving usually runs $1,200-$2,500, less than half the cost of a full removal.

Attic Insulation Replacement
Some Irving attics need everything removed first. We see this most in homes that suffered condensation damage during the February 2021 freeze, where wet insulation has matted down and lost its effectiveness. We also recommend removal and replacement when rodent activity has contaminated the existing material. Full replacement in Irving typically runs $2.50-$4.00 per square foot, with the final number depending on access, attic depth, and whether you’re adding air sealing at the same time.

Attic Baffles & Ventilation Prep
Baffles keep your soffit vents open so air can move through the attic. Without them, even brand-new insulation can trap heat and moisture against the roof deck. We install baffles along the eaves before blowing in new material, which matters in Irving where 100-degree days push attic temperatures above 150°F.

Common Attic Insulation Problems We See in Irving Homes
- Settled Valley Ranch fiberglass: Original 1980s blown-in insulation in Irving master-planned neighborhoods has compressed to under R-20, letting summer attic heat radiate into living spaces. We regularly see upstairs bedrooms running 10-15 degrees warmer than the rest of the house.
- Post-Uri condensation damage: The February 2021 freeze hit Irving’s 1960s-1980s tract homes hard. Near-zero air sealing meant warm, moist indoor air migrated into attics, condensed on the underside of roofs, and soaked insulation. That matted, mold-prone material still sits in thousands of Irving attics today.
- Missing or collapsed baffles: Many Irving homes have soffit vents that were never baffled during original construction. Insulation pushes against the roof deck, blocks airflow, and turns the attic into an oven. We fix this before adding any new material.
- Undersized attic access insulation: The pull-down stair or scuttle hole in your hallway ceiling is often just a thin piece of plywood with zero insulation. In Irving, that single weak point can account for a surprising slice of your cooling bill. We insulate and weatherstrip every access point as part of a proper job.

FAQs - Attic Insulation in Irving
Not usually. Most 1980s Valley Ranch homes just need a top-up over the settled original fiberglass, which costs far less than full replacement. But if the original insulation is water-damaged from Winter Storm Uri, matted with rodent droppings, or compressed to under R-10 in places, replacement is the smarter move. We’ll tell you which one your attic actually needs after a quick inspection, and we’ll show you what we’re seeing before you spend a dollar. Call (866) 751-4428 for an honest assessment.
Uri exposed that thousands of Irving homes built in the 1960s through 1980s had almost no air sealing and under-code attic insulation. Ice dams formed on roofs, pipes froze in attic spaces, and condensation soaked through insulation. The upgrade path now includes air sealing the attic floor before adding insulation, not just blowing more fiberglass on top. That’s the only way to protect against the next freeze event, and it’s now standard on every job we do in Irving.
Las Colinas commercial buildings from the 1980s often use raised-access-floor and plenum-ceiling insulation assemblies that were installed to pre-ASHRAE 90.1 specs, a retrofit niche that essentially only exists in Irving’s office core within the DFW market. These jobs require different certifications, load calculations, and bid structures than residential attic work, and most insulation companies in the area aren’t set up for them. We are. If you manage a Las Colinas property, call (866) 751-4428 and we’ll send someone who knows the difference between a plenum ceiling and a standard attic.
Yes, and in most 1990s Irving homes, baffles make a measurable difference. Soffit vents get blocked when insulation pushes against the roof deck, which traps heat and moisture and drives attic temperatures higher than they need to be. Installing baffles restores airflow, which lowers attic temperatures, extends shingle life, and helps your insulation actually perform at its rated R-value. We install baffles before every blown-in job as standard practice, not as an upsell.
For most Irving homes, blown-in fiberglass is still the best value. It hits R-38 or R-49 at a fraction of spray foam’s cost and performs well in vented attics, which is what most Irving houses have. Spray foam makes sense for unvented attics, homes with ductwork in the attic, or homeowners who want the air-sealing benefits built into the insulation itself. In Irving’s climate, spray foam also reduces the radiant heat load more aggressively during 100-degree weeks, but it’s an investment. We’ll quote both and let you decide with real numbers. Call (866) 751-4428 and we’ll walk you through the math for your specific attic.
Call Walt’s Insulation for Attic Insulation in Irving
Our crew recently topped up attic insulation in a Valley Ranch home where the original 1980s blown fiberglass had settled to under R-20, far below current Texas energy code. After air-sealing the attic floor and installing baffles at the eaves, we blew in Owens Corning AttiCat to R-38, and the homeowner reported the upstairs stayed noticeably cooler during the first 100-degree week. That’s the kind of result we aim for on every Irving job.
