CertainTeed Wall Insulation in Boerne: What to Know First
As an independent CertainTeed service provider, we handle wall insulation repair and upgrade work on CertainTeed products in Boerne and the surrounding Hill Country, typically scheduling within 48 hours and completing most jobs in a single day. Most CertainTeed wall insulation work in a home this size runs between $2,400 and $5,800 depending on wall area, access method, and whether the existing material can be salvaged or must be fully extracted. We do not start work without a written price, and we do not ask you to call for a quote - we’ll give you a flat number after inspection, before anyone lifts a tool. This page is for CertainTeed owners in Boerne who are seeing uneven wall temperatures, rising cooling bills, or who have been told their wall insulation has settled or failed. Call (830) 529-7780 to schedule a free estimate or a free second opinion on any written estimate you’ve already received.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed InsulSafe SP settling in balloon-framed walls. The loose-fill fiberglass was blown at adequate density in 2015, but Boerne’s wide humidity swings - 80% summer mornings dropping to 30% winter afternoons - cause the binder to fatigue over time. The material compacts in the lower third of wall cavities, creating a thermal bypass. We extract the settled product with a reverse-flow hose, then dense-pack with new material at 3.5 pounds per cubic foot so it stays put.
- CertainTeed SpeedyR fiberglass batts creating convection loops in 2×4 exterior walls. The kraft-facing adhesive fails when cavity humidity exceeds 70% for extended periods, which happens regularly in shaded Boerne homes near the Cibolo Creek basin. The batt detaches from the stud bay and sags, leaving a 2-inch air gap at the top. We remove the failed batts, air-seal the top plates and electrical penetrations with acoustic sealant, then reinstall with proper inset and a continuous interior air barrier.
- CertainTeed OPTIMA netted and blown system losing density at rim joists. The netting was stapled before the subfloor was fully dried during original construction, and the staples pulled through the OSB as it off-gassed moisture. The insulation settled into a U-shape, leaving the coldest part of the wall cavity essentially empty. We remove the compromised netting, treat for any moisture damage we find, then re-blow at the manufacturer’s specified density with new retention mesh.
- CertainTeed SmartBATT with MoistureSense reacting to actual - not perceived - moisture in Boerne’s limestone-heavy soil zones. The facing’s moisture-activated coating can trigger in walls that read dry on the interior but wick from the exterior through porous limestone mortar. Homeowners see stained facing and assume roof leakage. We test with a calibrated moisture meter at multiple depths, replace only the affected batts after addressing the source, and specify a vapor retarder appropriate to the wall’s actual drying potential.
- CertainTeed TrueComfort blown-in blanket system compressed by subsequent electrical or plumbing work. The original 1980s and 1990s installs in Boerne’s Fair Oaks Ranch and Balcones Creek areas were often pierced by retrofit trades who never restored the insulation. We find these with a borescope inspection, remove the compressed and displaced material, re-establish the full cavity depth, and blow to the original R-value specification with documented coverage verification.
Our CertainTeed Wall Insulation Process

- 1
Inspection and blower-door baseline. We run a pressurization test - a blower-door reading that shows, in one number, how much air your building envelope is losing. On a recent job near Boerne’s Main Street, the pre-test read 3,800 CFM50.
- 2
Cavity diagnosis with borescope and moisture meter. We look inside the wall without opening it, checking for settled product, detached facing, or moisture intrusion from the Hill Country’s occasional driving rains.
- 3
Written price and scope delivered. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No exceptions.
- 4
Air sealing first, then insulation. Seal the envelope first. Then fill it. We seal top plates, electrical boxes, and plumbing penetrations before any new material goes in.
- 5
Material installation with density verification. For blown products, we weigh the bag count against the cubic footage and spot-check with a core sampler. For batts, we verify inset depth and facing orientation.
- 6
Post-work blower-door test and documentation. We run the pressurization test again, hand you a printed pressure-differential report in pascals, and add the before-and-after numbers to your Documented Photo Record.

Why Boerne Homeowners Call Topside Attic Insulation Boerne for CertainTeed Work

We’ve worked on CertainTeed products in Boerne homes since 2016, and we’ve learned what fails first in this climate. The 365-Day Done Right Promise applies to every job - if it’s not done right, we make it right - and you get that in writing before the crew starts. Our technicians are background-checked and uniformed, and when you call (830) 529-7780, a live person answers, 24/7. Wes Okafor requires before-and-after blower-door numbers on every applicable job because a homeowner in the Hill Country deserves to see the performance change, not just hear about it. We also service Reflectix and other major brands, so if your home has mixed materials or you’re considering a change, we can compare options without pushing a proprietary product.
FAQs
No. As an independent CertainTeed service provider, we use warranty-safe installation practices and OEM-specified materials, but CertainTeed’s product warranty remains with the original manufacturer and is not affected by who performs the work. We document our installation method and materials used so you have a record if a product claim ever arises. Call (830) 529-7780 if you’d like us to review your warranty documents with you.
Yes. We maintain relationships with distributors who stock legacy CertainTeed products, and for lines that are fully discontinued, we specify compatible materials that match or exceed the original thermal and fire-performance ratings. We never substitute without documenting the equivalency in your written scope. For a specific parts check, call (830) 529-7780 with your product label information.
Repair is usually cheaper if less than 30% of the wall area is affected and the remaining insulation is still at specified density. Full replacement becomes the better value when we find widespread settling, moisture damage, or multiple trade penetrations that have compromised the original installation. We give you both numbers in writing so you can decide. Estimates are free - call (830) 529-7780 to schedule.
Most jobs are scheduled within 48 hours and completed in one day. Two-day jobs typically involve full extraction in a larger home or coordination with other trades. We do not manufacture urgency - we tell you the real lead time when you call. For current availability, call (830) 529-7780.
We handle mixed-brand homes regularly. Many Boerne properties have CertainTeed in walls installed during one renovation phase and Reflectix or another brand in attics or crawl spaces from another. We document what we find, specify the right material for each location, and never lock you into a single manufacturer’s product line. Call (830) 529-7780 to discuss your specific configuration.
