CertainTeed Insulation Removal & Replacement in San Antonio: What to Know First
CertainTeed insulation removal and replacement in San Antonio typically takes one to two days for most single-story homes, and we handle the job as an independent CertainTeed service provider, not a factory-authorized dealer. Pricing for a full attic removal and replacement usually lands between $2,400 and $5,800 depending on square footage, contamination, and which new material you choose. If your CertainTeed insulation has soaked up humidity, been torn up by rodents, or simply quit doing its job after years of San Antonio heat, call (866) 751-4428 and we’ll give you a straight answer on what it’ll take to fix it.
This page is for homeowners who already have CertainTeed insulation in their attic or walls and need it pulled out and replaced. We answer the phone live, every time.
How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes solid insulation products, but every material has a lifespan, and San Antonio’s climate shortens it. Here’s what we actually see in the field:
- CertainTeed InsulSafe fiberglass settles and loses loft. Blown-in InsulSafe is common in San Antonio attics, but after 10 to 15 years of thermal cycling plus the humidity swings we get from spring thunderstorms to 100-degree summers, the fibers compress. You end up with R-19 worth of insulation performing like R-11. We pull it all out, air-seal the attic floor, and blow in fresh material at the correct depth for Bexar County’s climate zone.
- CertainTeed batt insulation wicks moisture from air-handler condensation. In San Antonio, AC units in unconditioned attics sweat through long cooling seasons. CertainTeed fiberglass batts near the air handler act like a sponge. Once they’re damp, they mold, slump against the drywall, and lose thermal performance. We remove the affected batts, identify the condensation source, and replace with dry material after the moisture problem is addressed.
- Rodent damage in CertainTeed blown-in insulation. Rats and squirrels love tunneling through loose-fill fiberglass. We see it constantly in neighborhoods like Terrell Hills, Alamo Heights, and Stone Oak where mature trees give rodents a highway onto roofs. Torn, urine-soaked CertainTeed insulation has to go. We remove everything, rodent-proof the entry points, sanitize the attic floor, and blow in fresh insulation.
- CertainTeed OPTIMA fiberglass behind walls loses its air seal. OPTIMA is a dense-pack product installed behind netting. When the netting tears or settles over time, the fiberglass drops away from the top of the wall cavity. That leaves a gap where hot attic air pours into the wall. We open the affected cavities, vacuum out the old material, and dense-pack fresh insulation with the proper blower settings.
- Renovation contamination in CertainTeed-insulated attics. If you’ve had roof work, electrical work, or HVAC replacement done, your CertainTeed insulation is probably full of dust, debris, and stray fasteners. It’s not a manufacturer defect, but it means the material isn’t performing and it’s pulling dirt into your living space. We remove and replace it, and we run a quick attic inspection while we’re up there.
Our CertainTeed Insulation Removal & Replacement Process
Here’s how a CertainTeed job goes from the first call to the final walkthrough:
- 1
You call, a live person answers. No voicemail, no answering service. We ask what you’re seeing: high energy bills, temperature swings between rooms, visible rodent activity, or water stains on the ceiling.
- 2
We schedule the on-site inspection. A background-checked, uniformed technician shows up at the time we agreed on. Inside Bexar County, there’s no trip charge.
- 3
We measure and diagnose. The tech checks insulation depth, moisture levels, contamination, and air leakage. If you have a written estimate from another contractor, we’ll give you a free second opinion on it.
- 4
You get upfront pricing. One number, laid out in plain writing, covering removal, disposal, any air sealing, and the new insulation. No surprise line items at the end.
- 5
The removal and replacement. We use commercial HEPA-filtered vacuums to pull out the old CertainTeed material, sanitize where needed, air-seal the attic floor, and install your new insulation to the right depth for San Antonio’s climate.
- 6
We walk the job with you. Before we leave, you see what we did. Every job is backed by the Done Right Promise, our lifetime workmanship guarantee. If it’s not done right, we make it right.

FAQs
Adding new insulation on top of old CertainTeed material is cheaper in the short run, but it hides problems that get more expensive later. If the existing material is contaminated, matted down, or full of rodent waste, layering over it seals those problems into your attic. Pulling it out, air-sealing, and starting fresh costs more upfront but fixes the actual problem. Call (866) 751-4428 and we’ll inspect your attic and tell you which route makes sense.
Yes, in most cases. If your attic is accessible and the job is a straightforward removal without major contamination, we can often complete the removal and replacement in one day. Larger homes, multi-level attics, or heavy rodent contamination may take two days. We’ll give you a realistic timeline during the free estimate. Call (866) 751-4428 to schedule. No trip charge inside Bexar County.
No, removing old CertainTeed insulation does not void anything. Insulation warranties cover manufacturing defects, not removal or replacement after years of service. Once the material is out, you’re free to install any product you want. If you have documentation showing your CertainTeed insulation failed early, we can help you identify what to send to the manufacturer, but we won’t pretend to be the warranty department. We’re the company that gets the bad material out and good material in.
For most San Antonio attics, blown-in fiberglass or cellulose at the proper depth works well, and we install both. Spray foam is a better option if your attic houses an HVAC air handler or if you have ductwork that needs to move inside the thermal envelope. For walls, dense-pack fiberglass or injection foam both work. Your choice depends on your budget, your home’s construction, and whether moisture or pests are part of the picture. We’ll walk you through it, plainly, without upselling.
We answer the phone 24/7, and we keep our schedule flexible for attic emergencies like water leaks that have soaked insulation or rodent infestations that have made a mess. If we can’t get a technician out same day, we’ll be honest about that. Call (866) 751-4428 and we’ll tell you exactly when we can be there.
