Knauf Home Energy Audit in Schertz: What to Know First
We provide independent Knauf home energy audit in Schertz, typically completed same-day with written findings delivered before we leave. Most audits run between $280 and $450 depending on home size and whether duct leakage testing is included. We do not start any work without a written price, and we do not sell insulation to homeowners whose air leaks haven’t been measured first.
This page is for Knauf product owners in Schertz who want to know whether their insulation, air sealing, or duct system is performing as specified. That includes homeowners in newer subdivisions like Sedona off FM 1518 where Knauf Jet Stream blown-in fiberglass is common in tract builds, and owners of older Knauf EcoBatt batts in the original Schertz neighborhoods near I-35. If your utility bills are climbing and the attic looks fine from the hatch, the problem is usually invisible until a blower-door test proves it. Call (830) 402-5240 for a free estimate.
How Knauf Products Fail - and How We Fix Them
- Jet Stream Ultra settling in vented Schertz attics. This high-velocity blown-in fiberglass is spec’d at R-38 but often measures R-28 or lower within five years in our climate because attic ventilation pulls fine glass fibers toward the eaves, creating thin spots near the center of the bay. We map the depth with a calibrated stick every 24 inches, then supplement with matching Knauf Jet Stream or, if the homeowner prefers, transition to a stabilized blown-in product that resists convection.
- EcoBatt batts compressed by homeowner storage or contractor traffic. Knauf’s brown-formaldehyde-free batts recover poorly once walked on or boxed in. In Schertz, we see this most in 1980s-2000s builds near Schertz Parkway where the original R-30 batts have been compressed to R-15 effective. We remove the damaged batts, air-seal the top plates and electrical penetrations, then reinstall fresh product to full loft without compression.
- Knauf Insulation Board (NIB) thermal bridging at rim joists. The foil-faced polyiso boards specified for basement and crawl space rim joists in some Schertz builds delaminate when crawl humidity exceeds 65 percent, which happens regularly May through October here. The foil facing separates from the core, creating an air gap that nullifies the R-value. We pull the failed boards, seal the rim joist with closed-cell spray foam, and document the before-and-after with thermal imaging.
- Jet Stream MAX density inconsistencies from improper install speed. This product requires 3.5 to 4.5 pounds per minute through a 2.5-inch hose at 100 feet. Schertz crews working too fast create voids; too slow, and the binder activates early, clumping in the hose. We verify coverage with a box test before full deployment, and we publish the blower-door delta so the homeowner sees whether the install actually tightened the envelope.
- EcoSeal Plus water-based elastomeric sealant degradation in Schertz’s UV-exposed attics. Knauf’s companion air-sealing product, sometimes applied to top plates in newer builds, can chalk and crack when attic peak temps exceed 135°F - routine in Schertz from June through September. We inspect EcoSeal with a borescope during our audit, and if it’s failed, we remove the residue and replace it with polyurethane or acrylic sealant rated for sustained high-temperature exposure.
Our Knauf Home Energy Audit Process

- 1
Call and scheduling. A live person answers, or you text (830) 402-5240. We confirm square footage, year built, and any known comfort issues. You receive a written price range before we dispatch.
- 2
Blower-door test. We depressurize the house to -50 Pascals and measure CFM50 - the total air leakage in cubic feet per minute at that pressure. This is the baseline everything else is measured against.
- 3
Thermal imaging and visual inspection. We scan with a FLIR camera to find insulation gaps, thermal bridging, and air leakage paths. In Schertz, we pay particular attention to top plates, can lights, and duct boots in the attic, plus rim joists in crawl spaces.
- 4
Insulation depth and condition assessment. We probe Knauf products specifically for settling, compression, moisture staining, and pest damage. We photograph everything.
- 5
Duct leakage test (if included). We pressurize the duct system and measure leakage to outside. In Schertz’s sandy soil, we often find flex duct pulled loose at plenums where settling has strained the connections.
- 6
Written findings and next steps. You receive a printed report with blower-door number, thermal images, insulation map, and a written scope with flat pricing for any recommended work. No work starts without your signature on that scope.
What Knauf Home Energy Audit Costs in Schertz
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Basic home energy audit (blower door + thermal imaging + insulation inspection) | $280 - $350 | Home size, attic accessibility, number of HVAC zones |
| Audit with duct leakage testing | $380 - $450 | Duct accessibility, number of returns, need to seal registers for test |
| Follow-up verification blower-door test after our air sealing | $0 - $125 | Included free if we did the original audit; standalone if another contractor performed the work |
Homes over 3,500 square feet or with multiple attic accesses typically land in the upper third of these ranges. Crawl space encapsulation add-ons are priced separately after inspection. Every estimate is flat and written - no time-and-materials surprises. Call (830) 402-5240 for your exact number; estimates are free.
Why Schertz Homeowners Call Topside Attic Insulation Schertz for Knauf Work

We’re independently owned and operated under The Haven Standard since 2016, and we’ve sealed and insulated more than 9,000 homes with written prices before work started and documented records when the crew left. Our techs know Knauf’s product line because we install it, remove it, and audit it weekly - including the specific binder chemistry in Jet Stream that responds poorly to high humidity, and the recovery characteristics of EcoBatt after compression.
We also work with Reflectix and other major brands, so if your audit reveals that a different product suits your home better, we won’t push Knauf for the sake of inventory. Every applicable job gets before-and-after blower-door numbers published in your final packet. The 365-Day Done Right Promise applies to all completed work, and a live person answers calls 24/7.
Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
FAQs
No. Knauf’s limited warranty covers manufacturing defects in the original installed product, not the inspection of it. As an independent Knauf service provider, we document product condition without altering the warranty terms. If we find a manufacturing issue during audit, we flag it for your claim with Knauf directly. Call (830) 402-5240 to schedule - estimates are free.
Most audits are scheduled within 48 hours, and we complete the work same-day in about two to three hours. Emergency scheduling for pre-closing or insurance claim deadlines is available. Text or call (830) 402-5240 to confirm this week’s open slots.
Repair is viable when settling or minor compression is caught early and the product is less than ten years old. Replacement makes sense when the batt or blown-in product is moisture-damaged, pest-contaminated, or compressed below 50 percent of original thickness. Our audit gives you the depth measurements and thermal images to decide with real numbers, not guesses. Call (830) 402-5240 for a free estimate.
We source Knauf Jet Stream, EcoBatt, and Insulation Board through authorized distribution when the homeowner requests it or when matching existing product is required for consistency. We also install Johns Manville, Owens Corning, Rockwool, and other brands - no proprietary lock-in. Your written scope specifies exactly what product goes in before anyone lifts a tool.
A printed report with the blower-door CFM50 reading, dated thermal images with temperature annotations, an insulation depth map with probe locations marked, and a written scope with flat pricing for any recommended work. If duct testing was performed, you get the leakage-to-outside percentage. All of it is yours to keep, share with your HVAC contractor, or use for a second opinion. Call (830) 402-5240 to schedule - estimates are free.
