Owens Corning Wall Insulation in Canyon Lake: What to Know First
We provide independent Owens Corning wall insulation service in Canyon Lake, with most jobs completed in one day and a written price delivered before any work starts. Our typical wall insulation retrofit runs between $2,800 and $5,400 for a 2,000-square-foot home, depending on wall construction and access method. If you’re seeing uneven room temperatures, rising energy bills, or your Owens Corning insulation was installed before 2010, this page explains what we find and how we fix it. Call (737) 227-6219 for a free estimate with a written scope and warranty.
How Owens Corning Products Fail - and How We Fix Them
- PINK Fiberglas batts in 2×4 walls (R-13, pre-2012 formulations): Compression gaps at electrical boxes and plumbing chases let conditioned air bypass the batt entirely. In Canyon Lake’s cooling-dominated climate, this shows up as a south-facing room that won’t hold temperature below 78 degrees. We remove the compromised batts, seal top plates and penetrations with Owens Corning EnergyComplete acrylic latex sealant, then dense-pack with blown-in PINK Fiberglas L77 - a loose-fill product that fills irregular cavities without the compression points of batts.
- InsulPure blown-in cellulose in retrofit walls: Settling below the top plate after 5-7 years leaves a 6- to 12-inch thermal bypass at the header. We’ve found this in dozens of Canyon Lake homes near Startzville where the original contractor skipped the baffle installation. Our fix: infrared scan to map the void, then drill-and-fill through exterior siding or interior drywall to restore continuous coverage with new Owens Corning ProPink L77.
- FOAMULAR rigid foam board in basement or crawl space transitions: The foil facing delaminates in high-humidity conditions, which is most of summer in Comal County. Once the facing separates, the board loses its vapor-retarder function and can trap moisture against framing. We replace with fresh FOAMULAR 250, taped at seams with Owens Corning JointSealR foam tape, and integrate with wall cavity insulation so the thermal boundary stays continuous.
- Ecotouch batts with Kraft facing: The asphalt-impregnated paper facing degrades in wall cavities with intermittent moisture drive - common in Canyon Lake’s hill-country construction where wind-driven rain hits gable walls hard. The facing becomes brittle and falls away from the batt, creating an air gap. We remove the degraded material and switch to unfaced Ecotouch R-15 batts with a separate smart vapor retarder where code requires it.
- AttiCat blown-in system in walls (improper application): Some contractors ran AttiCat PINK Fiberglas through sidewall cavities, but the lower density of attic-blown material settles dramatically in vertical applications. We’ve pulled 40% settled material from walls in homes off FM 306. The correction is dense-pack injection at 3.5 pounds per cubic foot minimum, verified by fill tube resistance and thermal imaging.
Our Owens Corning Wall Insulation Process

- 1
Call and schedule. A live person answers (737) 227-6219 24/7. We book a site visit, and under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Blower-door test and infrared survey. We pressurize the house to measure CFM50 - how much air the envelope is losing - then thermal-map the walls to locate voids, compression, and bypasses. The customer receives a printed pre-work report.
- 3
Written price and scope. Flat price, written scope, written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions.
- 4
Air sealing first, then insulation. Top plates, electrical penetrations, plumbing chases, and window bucks get sealed with compatible Owens Corning sealants or specified third-party products. Seal the leaks first. Then insulate. The report tells you whether it worked.
- 5
Material selection and installation. We specify Owens Corning ProPink L77, Ecotouch batts, or FOAMULAR rigid board based on the cavity condition and climate zone requirements. OEM-specified installation methods are followed to preserve any remaining manufacturer warranty coverage.
- 6
Post-test, photo record, and documentation. Second blower-door test to verify air-sealing results. Before-and-after numbers published on the job record. Documented Photo Record delivered. 365-Day Done Right Promise in effect.

AfterWhat Owens Corning Wall Insulation Costs in Canyon Lake
| Scenario | Typical Range |
|---|---|
| Drill-and-fill exterior walls, 1,800 sq ft home | $2,800 - $4,200 |

Price movers: wall cavity depth (2×4 vs. 2×6), exterior access vs. interior drywall removal, existing material condition requiring removal, and whether the home needs companion attic air sealing to meet performance goals. We also source from Johns Manville, Knauf, Rockwool, and other manufacturers if the job specification calls for it - no proprietary lock-in.

Why Canyon Lake Homeowners Call Topside Attic Insulation Canyon Lake for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Canyon Lake teach you something specific: the combination of hill-country temperature swings and lake-effect humidity means insulation that performs on paper often fails in the wall. Wes Okafor runs a blower-door test before every job because a number without context is just noise - and because homeowners here deserve to see the CFM50 drop in writing, not take someone’s word for it.
Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7. The 365-Day Done Right Promise applies to all completed work. And because we also service Reflectix and other brands, we’re not pushing one product line to fit every house. We specify what the assembly needs.
FAQs
No - manufacturer warranties on insulation materials cover product defects, not installation workmanship. As an independent Owens Corning service provider, we follow OEM installation specifications so material warranties remain intact; our 365-Day Done Right Promise covers the labor and air-sealing performance separately. Call (737) 227-6219 and we’ll walk through what’s covered by whom.
Yes - Owens Corning ProPink L77 dense-packed at 3.5 pounds per cubic foot achieves R-15 in a 2×4 cavity, matching or exceeding original batt performance without the compression gaps. The key is air sealing the cavity first so the insulation isn’t fighting wind washing through electrical penetrations. We’ll show you the blower-door numbers before and after.
Repair is usually 40-60% less when the existing material is dry and accessible through drill-and-fill. Gut-and-replace makes sense when there’s moisture damage, rodent contamination, or the cavity needs structural repair first. We quote both paths with a written scope so you can compare actual numbers, not guesses. Call (737) 227-6219 for the assessment.
Most homeowners get a site visit within 48 hours and work starts within a week of written approval. Same-week scheduling is often available outside peak summer demand. A live person answers (737) 227-6219 to check current openings.
We maintain standard Owens Corning inventory - ProPink L77, Ecotouch batts, FOAMULAR 250, EnergyComplete sealant - at our Canyon Lake-area warehouse. Specialty items or large rigid-board orders typically arrive in 3-5 business days. We’ll confirm material availability and timeline in your written scope before you approve the job.
