CertainTeed Blown-In Insulation in Converse: What to Know First
We install and service CertainTeed blown-in insulation in Converse as an independent CertainTeed service provider - not affiliated with or authorized by the manufacturer. Most attic jobs run same-day to two days from written price to completion, and you’ll get that written price before anyone touches your attic. We don’t do “call for a quote” because Haven Standard Clause 1 requires a flat price, written scope, and written warranty before work starts.
This page is for Converse homeowners who already have CertainTeed insulation in their walls or attic and need a top-up, replacement, or troubleshooting after settling, moisture damage, or pest intrusion. If you’re seeing uneven temperatures between rooms, dust streaks around outlets, or your HVAC running longer than it used to, the insulation may have shifted or degraded. Call (830) 420-0953 and a live person will pick up, 24/7.
How CertainTeed Products Fail - and How We Fix Them
- InsulSafe SP settling in Converse ranch attics. This fiberglass blown-in product is common in 1990s-2010s builds near Foster Road and Woodlake, where it was often blown to R-30 over unsealed top plates. Over 10-15 years, vibration from HVAC ducting and foot traffic during cable installs compresses it to R-19 or lower. We remove the settled material, seal every top-plate penetration and can-light gap with fire-rated caulk and rigid baffles, then blow fresh InsulSafe SP to the original design thickness. The blower-door test before and after shows the difference.
- TrueComfort cellulose moisture uptake in vented attics. CertainTeed’s cellulose line holds borates for fire and pest resistance, but in Converse’s humid shoulder seasons - March through May and September through November - poorly vented attics trap moisture against the product. It cakes on the attic floor, creating a thermal bridge where R-value plummets locally. We find this by probing with a moisture meter and infrared camera, remove the affected batts or loose fill, address the ventilation deficiency, then reinstall with proper soffit-to-ridge airflow.
- Optima dense-pack settling in 2×4 walls. This wet-spray cellulose was designed for open-wall new construction, but some Converse remodelers dense-packed it dry into existing walls through drill holes. Without the adhesive activation of wet-spray application, it settles 15-25% in the first two years, leaving a cold zone at the top of each stud bay. We drill new access holes near the ceiling, re-densify with proper equipment to 3.5 lbs/cubic foot, and patch with matching texture.
- SmartBaffle failure in steep-slope attics. CertainTeed’s vent baffle is meant to keep soffit airflow above the insulation, but in Converse’s older homes with 4:12 or 5:12 roof pitches - common in the Rolling Meadows area - the baffle can collapse under the weight of blown-in product if not stapled to code. We find collapsed baffles blocking airflow and causing ice-dam conditions on north faces in January. Our fix: remove and replace with rigid-site-built baffles, then re-blow to a uniform depth with depth markers every 64 square feet.
- CertaSpray open-cell shrinkage at perimeter rim joists. While technically a spray foam product, CertaSpray open-cell is often found in hybrid jobs alongside CertainTeed blown-in in attics. In Converse’s clay-heavy soils, foundation settling cracks the foam at the rim joist, creating a convection loop that pulls attic air down into the wall cavity. We cut back the failed foam, reseal with closed-cell at the rim, and verify with blower-door and infrared before calling the job complete.
Our CertainTeed Blown-In Insulation Process
- 1
Call and schedule. A live person answers at (830) 420-0953. We book a 2-hour arrival window and text you when the technician is en route - Haven Standard: Arrive on schedule.
- 2
Attic inspection and blower-door baseline. We run a blower-door test - pressurizing the house to 50 pascals and measuring air leakage in CFM50 - then probe insulation depth, take moisture readings, and shoot infrared to find thermal bypasses. You get a Documented Photo Record of everything we find.
- 3
Written price and scope. Before any work starts, you receive a flat price, written scope, and written warranty. No exceptions. This is Haven Standard Clause 1. We also offer a Free Second Opinion on any competing written estimate.
- 4
Air sealing first, then insulation. We seal top plates, can lights, chimney chases, and duct penetrations with fire-rated materials. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
- 5
Blown-in installation to spec. We install CertainTeed, Owens Corning, Johns Manville, Knauf, Rockwool, or GreenFiber - whatever matches your existing system and performance goals. Depth markers go in every 64 square feet for verifiable coverage.
- 6
Blower-door retest and documentation. We run the blower-door again, print the before-and-after report, and leave you with the written warranty, photo record, and our 365-Day Done Right Promise. If it’s not done right, we make it right.
Before
AfterWhat CertainTeed Blown-In Insulation Costs in Converse
Most attic top-up jobs in Converse run $1,400 to $2,800 for homes between 1,200 and 2,400 square feet. Full removal and replacement of settled or contaminated product runs $2,800 to $5,200. Dense-pack wall work for a single-story ranch runs $3,200 to $5,800 depending on wall area and access.
What moves the price: how much existing material needs removal, whether we find unsealed penetrations that should have been handled at original install, and access complexity - low-pitch attics under 4:12 take longer to move in safely. We don’t upcharge for CertainTeed versus other brands; the labor and air-sealing rigor are the same.
Every estimate is free, every price is written before work starts, and we publish blower-door numbers so you can verify what you paid for. Call (830) 420-0953 for your exact number.
Why Converse Homeowners Call Topside Attic Insulation Converse for CertainTeed Work
We’ve sealed and insulated over 9,000 homes since 2016, and the Converse jobs stick in our memory - ranch homes near Foster Road with unsealed top plates bleeding conditioned air since 1978, Woodlake two-stories where the original builder blew fiberglass over recessed cans without fire-rated covers. Wes Okafor and our crew know what CertainTeed products look like after 10 years in this climate because we’ve pulled enough of it out to fill a warehouse.
We also work with Reflectix and every major brand - Owens Corning, Johns Manville, Knauf, Rockwool, GreenFiber - so if your CertainTeed system needs a compatible supplement or full replacement, we don’t force a proprietary match. The 365-Day Done Right Promise, before-and-after blower-door numbers, and Documented Photo Record come on every job. Calls are answered by a live person, 24/7.
FAQs
No - but CertainTeed’s product warranty covers manufacturing defects, not installation or settlement issues, regardless of who touches it. As an independent CertainTeed service provider, we document our work with photos and blower-door readings so any future claim has a clear baseline. If you have a current product warranty concern, we can photograph and sample the material for your records. Call (830) 420-0953 and we’ll walk through what’s covered and what isn’t.
We source CertainTeed products through standard distribution channels and match them with quality-compatible materials from Owens Corning, Johns Manville, Knauf, Rockwool, or GreenFiber when the original line is discontinued or when a different product better solves the problem. We don’t claim exclusive or preferred status with any brand. The written scope specifies exactly what goes in your attic before work starts.
Repair - meaning re-fluffing and adding top-up material - runs 40-60% less than full removal and replacement, but only makes sense if the existing product is dry, uncontaminated, and the air sealing beneath it was done right the first time. In most Converse attics we inspect, the sealing wasn’t done right the first time, so we recommend removal, full seal, and re-blow. We’ll show you the infrared and moisture-meter readings and give you both prices in writing. Free estimates, no obligation.
Most attic jobs are completed same-day or next day after you approve the written price. Dense-pack wall work takes 2-3 days including drying time for patch compound. We don’t schedule until you have the written scope and price in hand, so there’s no pressure to decide on the spot. Call (830) 420-0953 - a live person answers 24/7.
You receive a printed blower-door report with before-and-after CFM50 readings, a Documented Photo Record of the attic before, during, and after, the written warranty, and our 365-Day Done Right Promise in writing. Haven Standard: you know what leaving looks like before we arrive.
