Demilec Home Energy Audit in Round Rock: What to Know First
We provide independent Demilec home energy audit in Round Rock, typically scheduled within 48 hours and completed in a single visit. Most audits run $280-$450 for a standard single-family home, and you’ll receive a written scope with flat pricing before any work starts - that’s Haven Standard Clause 1, no exceptions. This page is for Demilec owners in neighborhoods like Behrens Ranch, Fern Bluff, and Forest Creek who’ve noticed uneven temperatures, rising utility bills, or suspect their spray foam isn’t performing as specified. Call (737) 259-7528 for a free estimate or to schedule your audit.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO High Lift shrinkage in vented attics. This closed-cell foam can pull away from rafter edges in Round Rock’s temperature swings, creating thermal bypasses we catch with blower-door-directed infrared. We mark every gap, re-establish adhesion with compatible HFO touch-up foam, and verify with a post-repair pressurization reading.
- Demilec SEALECTION 500 density loss in crawl spaces. The 0.5 lb open-cell product absorbs moisture over time in our clay-heavy Williamson County soils, degrading from its original R-3.6 per inch. We pull core samples during audit, document density with photos, and specify removal plus replacement with a closed-cell alternative if the material has fallen below manufacturer spec.
- Heatlok XT adhesive failure on OSB roof decks. When attic humidity spikes during Austin’s spring storm season, this medium-density foam can delaminate from sheathing. Our thermal imaging pinpoints these separations, and we cut back to sound substrate before reapplying - never skin-coating over failed material.
- SEALECTION Agribalance overspray into soffit vents. This water-blown open-cell foam expands aggressively; installers sometimes miss blocked intake vents that later starve ridge vents of makeup air. We find these during our blower-door test - the house won’t depressurize properly - and clear them without damaging the surrounding foam envelope.
- Demilec foam around recessed can lights creating fire-code violations. Older Heatlok applications in Round Rock’s 1990s-era stock often encroach on non-IC-rated fixtures. We identify these during insulation inspection, document with photos for your records, and specify proper enclosures or fixture replacement to bring the assembly back to IRC compliance.
Our Demilec Home Energy Audit Process
- 1
Call and scheduling. A live person answers, 24/7. We book your Round Rock audit, send a text with your technician’s name, and confirm the appointment window.
- 2
Blower-door test first. We pressurize the house to 50 Pascals and record your CFM50 baseline - the single number that tells us how much conditioned air your envelope is hemorrhaging before we touch anything.
- 3
Thermal imaging and physical inspection. With the house under pressure, we scan with infrared to find Demilec-specific failure patterns: shrinkage lines, delamination pockets, moisture-laden open cell. We photograph everything.
- 4
Written scope and flat price. Before any repair, you get a written price, the work described in detail, and our 365-Day Done Right Promise in writing. No work starts without it.
- 5
Air sealing before any insulation touch. We seal the leaks first. The insulation has nowhere to go until you do. Top plates, can lights, penetrations - sealed with compatible materials, never generic caulk over Demilec foam.
- 6
Post-work verification and documentation. We run the blower door again, publish your before-and-after numbers, and leave you with a Documented Photo Record and the written warranty.
What Demilec Home Energy Audit Costs in Round Rock
| Service | Typical Range |
|---|---|
| Full home energy audit (blower door, thermal imaging, insulation inspection) | $280-$450 |
| Duct leakage test add-on | $125-$195 |
| Demilec foam remediation (localized shrinkage/delamination repair) | $680-$1,400 |
| Full attic Demilec removal and replacement | $3,200-$5,800 |
| Crawl space encapsulation with vapor barrier (where SEALECTION 500 has failed) | $2,800-$4,500 |
What moves the price: attic square footage, accessibility (steep-pitched 12/12 roofs in Old Town Round Rock add time), whether the Demilec failure requires full removal or localized repair, and whether we find code violations that must be addressed. We also service Reflectix radiant barrier systems when they’re part of the same assembly.

Why Round Rock Homeowners Call Topside Attic Insulation Round Rock for Demilec Work
We’ve sealed and insulated 9,000+ homes since 2016, and we’ve learned that Demilec foam demands a specific diagnostic approach - the same shrinkage pattern that looks like a thermal bridge on infrared might actually be a installation-phase timing issue, not material failure. Our technicians know the difference because they’ve handled Demilec products across Round Rock’s full housing stock, from 1980s ranches in Meadow Lake to new builds in Paloma Lake. Every job gets before-and-after blower-door numbers, every job gets a written price first, and every job is backed by our 365-Day Done Right Promise. We’re independently owned and operated - not a Demilec authorized dealer - which means we specify what actually fixes your envelope, not what moves a particular product line.
FAQs
Demilec’s material warranty covers manufacturing defects, not installation errors or environmental degradation - which is what we most often find in Round Rock audits. As an independent Demilec service provider, we document our findings so you can pursue installer liability if the application was defective. Call (737) 259-7528 and we’ll review your original paperwork with you.
We source OEM Demilec products when the repair must match existing foam chemistry for adhesion compatibility - Heatlok to Heatlok, SEALECTION to SEALECTION. For some localized repairs, we use quality third-party HFO or open-cell products that test compatible, and we disclose which before you approve the scope. The written price specifies the material by name.
Localized shrinkage or delamination under 10% of total foam area usually qualifies for targeted repair; widespread density loss, moisture saturation, or fire-code violations typically require removal. We make this determination with core samples and infrared evidence, not guesswork, and we show you the photos before you decide. Call (737) 259-7528 to schedule the audit that answers this for your specific house.
Most Round Rock homeowners get an appointment within 48 hours, and the audit itself takes 2-3 hours. Same-day scheduling is often available for active moisture intrusion or visible foam degradation. A live person answers (737) 259-7528 around the clock.
No - and we won’t do it. Blowing fiberglass or cellulose over unsealed bypasses or failed Demilec foam traps moisture, hides the real problem, and often makes it worse. Our Haven Standard requires air sealing before any insulation work; if your Demilec has failed, we specify the proper remediation first. Call for a free estimate and we’ll show you exactly what we found.
