Demilec Home Energy Audit in Cedar Park: What to Know First
We provide independent Demilec home energy audit in Cedar Park, typically scheduled within 48 hours and completed in a single visit. Most audits run between $280 and $550 depending on home size and test scope, and you’ll get a written price before we start - no exceptions. This page is for Demilec owners in Cedar Park who want to know whether their spray foam insulation is performing as specified, whether air leaks are undermining it, and what the actual numbers say. Call (737) 245-6428 to schedule or text us if you prefer.
How Demilec Products Fail - and How We Fix Them
- Demilec Heatlok HFO Pro shrinkage in Cedar Park attics. The HFO blowing agent can contract 3-5% in our 140°F summer peak attic temperatures, creating gaps at stud bays and rim joists. We find this with thermal imaging, then cut back the failed section and re-foam with a compatible high-temperature formulation - never just caulk over the gap.
- Demilec Sealection 500 density loss in older Butter Creek Creek installs. Open-cell foam installed 2012-2018 in this area sometimes dropped below 0.5 lb/ft³, meaning it no longer blocks convective airflow. Our blower-door test catches this when post-sealing CFM50 barely drops despite visible foam. We remove the degraded layer and reinstall to spec.
- Demilec Heatlok XT poor adhesion to OSB roof sheathing. When roof decks hit 160°F in July, the XT skin can delaminate, leaving a paper-thin air gap that kills R-value. We document this with borescope photos, then mechanically fasten a new layer after proper surface prep.
- Demilec 500 open-cell moisture retention in vented crawl spaces. Cedar Park’s clay-heavy soils wick moisture upward; open-cell below-grade can hit 20% wood moisture equivalent and support mold. We test with calibrated moisture meters, and when we find it, we replace with closed-cell or encapsulate the crawl first.
- Demilec spray foam occluding soffit vents after retrofit. Previous installers sometimes filled the entire rafter bay, blocking intake ventilation and cooking the roof. Our audit includes a vent flow check with a handheld anemometer; if airflow’s dead, we surgically remove foam from the vent channel and install proper baffles.
Our Demilec Home Energy Audit Process
- 1
Call and scope. You describe the Demilec product line if you know it, the install year, and what prompted the call. We quote a written price before scheduling.
- 2
Pre-install blower-door test. We pressurize to -50 Pascals and record CFM50 and ACH50 - the pressure-to-airflow figures that tell us exactly how leaky the envelope is before we touch anything.
- 3
Thermal imaging and borescope inspection. We map foam continuity, check for shrinkage gaps, delamination, and moisture intrusion. Every finding gets a photo.
- 4
Duct leakage test if indicated. When the home has Demilec in the envelope but the HVAC still can’t keep up, we run a Duct Blaster to see if conditioned air is escaping the duct system, not the envelope.
- 5
Written report with options. We specify OEM Demilec repair, compatible aftermarket alternatives, or removal and replacement - with prices for each path. No work starts until you approve in writing.
- 6
Post-work verification. On any air-sealing correction, we rerun the blower door and publish your before-and-after numbers. You leave with the photos, the readings, and the warranty.

What moves the price: home size, attic accessibility, whether we need to run a duct Blaster, and whether the Demilec failure requires surgical repair or full removal. We also service Reflectix radiant barrier systems when they’re part of the same envelope. Call (737) 245-6428 for an exact quote - estimates are free.

We’re independently owned and operated under The Haven Standard since 2016, and we’re not affiliated with or authorized by Demilec - we work on their products as an independent service provider. Wes Okafor brought blower-door discipline from Chicago’s building science program to Cedar Park, and we’ve run audits across this market including retrofits in Buttercup Creek where summer attics hit 140°F. Our 365-Day Done Right Promise covers all completed work, and every job closes with a Documented Photo Record. Calls are answered by a live person 24/7, and we publish before-and-after blower-door numbers on every applicable job so you can verify the result yourself. Seal the leaks first. Then insulate. The order matters more than the product.
FAQs
No - Demilec’s warranty covers material defect, not who touches it. However, improper repair technique can void your installer’s workmanship warranty, which is why we document our scope in writing before starting and use foam compatible with your existing Demilec chemistry. Call (737) 245-6428 and we’ll review your warranty paperwork with you.
We can source OEM Demilec products when the repair is small and the chemistry match matters; for larger remediation, we often recommend compatible formulations from Icynene or other manufacturers we stock - same performance, sometimes better availability. We never lock you into a proprietary product.
Localized shrinkage or delamination usually runs $180-$340 to repair; widespread density loss or moisture damage typically costs more to fix properly than to strip and reinstall. We give you both numbers and let the math decide. Call (737) 245-6428 for a free second opinion on any estimate you’ve already received.
Most audits are scheduled within 48 hours, same day if you call early and it’s urgent - like a roof delamination discovered during a home sale inspection. We don’t do callback windows measured in business days.
We calibrate our Retrotec or Minneapolis Blower Door fans annually and run them per ASTM E779 protocol. You get the raw CFM50, the ACH50 calculated to your home’s volume, and the photos of the setup so you can verify the test conditions. That’s Haven Standard documentation - have it in writing.
