Demilec Home Energy Audit in Boerne: What to Know First
We provide independent Demilec home energy audit in Boerne, typically scheduling within 48 hours and completing the full diagnostic same day. Most audits run $280-$520 depending on home size and whether duct-blaster testing is needed, and we put that price in writing before any work starts. This page is for Demilec owners in Boerne who want to know why their spray foam or air-barrier system isn’t performing the way the brochure promised, and what a blower-door test will actually reveal. Call (830) 529-7780 to schedule or text us if you prefer.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO Pro shrinkage at roof decks in Boerne’s summer heat. The HFO blowing agent can lose volume faster than legacy HFC products when attic temperatures spike above 140°F in July and August. We see this most in homes off Esser Road and near the Balcones Creek rim where roof ventilation is marginal. Our fix: thermal imaging to map the shrink gaps, then targeted injection with Demilec-approved HFO refill or strategic retrofit with Knauf open-cell depending on the assembly.
- Demilec 500 open-cell moisture retention in crawl spaces over the Cibolo watershed. Open-cell’s vapor permeability becomes a liability when relative humidity in a vented crawl space stays above 70% for weeks. We’ve pulled saturated 500-series foam off band joists in Boerne homes where the vapor drive was simply misdiagnosed at install. Our fix: hygrometer logging first, then either closed-cell replacement or full encapsulation with a mechanical dehumidifier tied into the audit report.
- Sealection 500 delamination from OSB sheathing after repeated wetting. The adhesive bond fails when bulk water gets behind the foam through a flashing defect, then dries. The foam looks intact but has an air gap you can’t see. Our fix: smoke-pencil tracing at the perimeter, selective removal, substrate drying verification with a moisture meter, then reapplication with proper drainage plane integration.
- Demilec Agribalance inconsistent lift thickness in retrofit attic floors. The soy-based content can settle slightly if the installer rushes the pass pattern, leaving thin spots that read fine on infrared but leak at the blower door. Our fix: core sampling through the audit, then either supplemental blown-in GreenFiber to even the thermal layer or full removal and re-spray with documented lift charts.
- Heatlok XT adhesive failure on metal ductwork in unconditioned attics. The XT series bonds aggressively to galvanized steel, but thermal cycling between 40°F winter nights and 130°F summer afternoons can shear the interface after five to seven years. Our fix: duct-blaster testing to quantify the leakage, then either Demilec-compatible mastic reseal or transition to Reflectix-backed flex with mechanical support.
Our Demilec Home Energy Audit Process
- 1
Call and scheduling. A live person answers, 24/7. We ask square footage, year built, and any known comfort complaints. You get a text with your technician’s name and a 30-minute arrival window.
- 2
Visual and interview. We walk the house with you, note the Demilec product line if visible, and photograph the install condition. We want to know if the original contractor provided blower-door numbers.
- 3
Blower-door test. We depressurize to 50 pascals and record CFM50, then use a smoke pencil and infrared camera to map leakage paths. This is the baseline everything else is measured against.
- 4
Thermal imaging and targeted diagnostics. We scan for foam shrinkage, delamination, missing coverage, and thermal bridging. If ducts are in the attic, we run a duct-blaster test for leakage to outdoors.
- 5
Written findings and price. You get a printed report with photos, the blower-door number, and a flat price for any remediation. No work starts without your signature on that price.
- 6
Remediation and verification. If you proceed, we seal first, then insulate. Afterward, we rerun the blower door and hand you the before-and-after report. The photo record goes to your email same day.
What Demilec Home Energy Audit Costs in Boerne
| Service | Typical Range |
|---|---|
| Basic home energy audit (blower door + thermal imaging) | $280-$380 |
| Audit with duct-blaster testing | $380-$520 |
| Targeted air sealing after audit findings | $450-$1,200 |
| Demilec foam remediation (partial, per area) | $800-$2,400 |
| Full attic re-insulation after removal | $2,800-$5,500 |
What moves the price: home size, attic accessibility, whether the Demilec foam needs partial removal, and if we’re chasing a comfort complaint in a specific room versus a whole-house efficiency target. We also factor in whether your home is pre-1980 with knob-and-tube wiring that has to be worked around. Every estimate is free, and we offer a free second opinion on any written estimate you’ve already received. Call (830) 529-7780 for an exact quote.
Why Boerne Homeowners Call Topside Attic Insulation Boerne for Demilec Work
We’ve been independently owned and operated under The Haven Standard since 2016, and our 365-Day Done Right Promise applies to every job. Wes Okafor runs the blower door himself on complex Demilec diagnostics, and our crews know the difference between Heatlok HFO and Agribalance application requirements without checking a cheat sheet. We don’t lock you into proprietary products - we source Demilec, Reflectix, Owens Corning, Johns Manville, and others, so the fix matches the problem, not our inventory. Every visit produces a Documented Photo Record, and we publish before-and-after blower-door numbers on every applicable job so you can verify the result in pascals, not promises. Calls are answered by a live person, 24/7, and we text when the technician is on the way.
FAQs
No. As an independent Demilec service provider, our diagnostic work does not alter or invalidate any existing manufacturer warranty. We document condition without modifying the foam unless you authorize remediation separately. If we find an install defect that falls under Demilec’s coverage, we flag it in our report so you have documentation for your claim. Call (830) 529-7780 if you want us to review your warranty paperwork during the audit.
Most audits are scheduled within 48 hours, and we complete the full diagnostic same day. Emergency comfort complaints in summer get priority, especially when a failed foam barrier is forcing the HVAC to run continuously. We answer calls live 24/7, so you’re not waiting through a voicemail loop while your attic hits 150°F. Call (830) 529-7780 to check today’s availability.
Repair makes sense when the failure is localized shrinkage or delamination under 15% of the total area and the substrate is dry. Full removal and replacement is the better call when moisture has compromised the foam-to-substrate bond across multiple planes, or when the original product was open-cell in a closed-cell application. Our audit gives you the moisture-meter readings and thermal images to make that decision with numbers, not guesses. Estimates are free.
We carry Demilec-compatible HFO refill kits, touch-up foam, and vapor-barrier retrofit materials on our Boerne trucks. For full re-spray jobs requiring bulk Demilec product, we order direct and typically have material within three business days. We also keep Reflectix and Owens Corning alternatives in stock when the audit shows a different product is the better fix. We never leave you waiting because we locked ourselves into one supplier.
You get a printed blower-door report in CFM50 with the before number, a thermal imaging summary with annotated photos, a written scope of any recommended work with a flat price, and a Documented Photo Record emailed same day. If we perform remediation, you also get the after blower-door number and the pressure-differential report in pascals. Every document is dated and signed by the technician who was in your attic.
Ready to find out what your Demilec system is actually doing? Call (830) 529-7780 for a free estimate. We’ll put the price in writing before any work starts, and you’ll have the blower-door numbers to know whether the fix worked.
