Demilec Home Energy Audit in Pflugerville: What to Know First
We provide independent Demilec home energy audit in Pflugerville as an unaffiliated service provider, with same-day or next-day scheduling for most calls and a written price delivered before any work starts. A typical Demilec audit runs $280-$480 for a single-zone system, and you’ll receive documented blower-door readings and thermal imaging - not a verbal summary. This page is for Pflugerville homeowners who installed Demilec spray foam between 2012 and 2021 and are now seeing uneven temperatures, rising utility bills, or moisture indicators that suggest the envelope has shifted. Call (737) 259-8352 for a free estimate with a written scope.
How Demilec Products Fail - and How We Fix Them
- Demilec SEALECTION 500 open-cell foam shrinkage at top plates. In Pflugerville’s clay-heavy soils, seasonal foundation movement stresses the foam-to-wood bond at the attic perimeter. We find 3-8% linear shrinkage in homes built 2014-2018, creating a convection channel that bypasses the R-value entirely. We cut back the degraded foam, seal the gap with closed-cell touch-up, and re-test with the blower door to confirm the CFM50 drop.
- Demilec Heatlok Soya HFO cold-weather application defects. This line was specified heavily in the Stone Hill Town Center builds during 2016-2019, and batches applied below 40°F substrate temperature never achieved full rise density. The result: internal voids we locate with FLIR thermal imaging, then drill and inject with compatible two-component foam rather than tearing out intact surrounding material.
- Demilec 500 Demi-Fresh off-gassing and indoor air quality complaints. The citrus-oil additive in this residential line breaks down under sustained attic heat above 140°F - common in Pflugerville’s west-facing roof planes. We don’t just mask odor; we remove the degraded foam layer, ventilate the cavity to safe VOC levels verified with a photoionization detector, and reinstall with a non-amine formulation.
- Demilec Agribalance shrinkage at rim joists in crawl spaces. The higher bio-content in this series absorbs seasonal moisture in Pflugerville’s spring humidity spikes, then releases it as dimensional change. We see this most in the Windermere and Blackhawk neighborhoods where crawl space encapsulation was omitted. Our fix: remove the compromised Agribalance, install a proper vapor barrier, then re-foam with a hydrophobic closed-cell alternative.
- Demilec SEALECTION Agri-Bond delamination from OSB roof sheathing. The adhesive interface fails when roof leaks - even minor ones from wind-driven rain on shallow-pitch sections - saturate the foam before the sheathing dries. We map the delaminated zones with moisture meters, remove only the affected foam, treat the sheathing with borate if mold is present, and reapply with a primer-compatible closed-cell system that bonds to damp-tolerant substrates.
Our Demilec Home Energy Audit Process

- 1
Schedule and scope. You call (737) 259-8352; a live person answers. We confirm your Demilec product line from installation records or visual ID, and email a written price range before the appointment.
- 2
Blower-door baseline. We run a pressurization test - a measurement that shows, in one number, how much conditioned air your building envelope is losing. This is your pre-job CFM50, documented with photos of the manometer reading.
- 3
Thermal imaging and physical inspection. Our tech scans with FLIR for voids, shrinkage, and delamination, then probes suspect areas with a moisture meter and core samples where needed. We photograph every anomaly.
- 4
Diagnosis and repair plan. We identify whether your issue needs OEM Demilec touch-up foam, compatible third-party material, or removal and replacement. We explain the trade-offs in writing - no verbal-only recommendations.
- 5
Repair, re-test, and documentation. We complete the air sealing or foam work, run a second blower-door test, and hand you a written report with before-and-after CFM50 numbers, thermal images, and a 365-Day Done Right Promise backed by Haven Standard warranty language.
Before
AfterWhat Demilec Home Energy Audit Costs in Pflugerville
| Scenario | Typical Range | What Moves Price |
|---|---|---|
| Single-zone blower door + thermal imaging audit | $280-$380 | Home size, attic accessibility, number of HVAC zones |
| Audit with localized Demilec foam remediation (touch-up, under 50 sq ft) | $420-$680 | Foam type (open-cell vs. closed-cell), height of application, containment needs |
| Full removal and replacement of failed Demilec in one cavity zone | $1,800-$3,200 | Volume of foam, disposal requirements, substrate repair, re-insulation |
| Crawl space encapsulation + Demilec Agribalance replacement | $2,400-$4,500 | Linear feet of wall, vapor barrier grade, dehumidifier specification |
Prices include the Documented Photo Record and written scope; they do not include optional add-ons like whole-home duct sealing or radiant barrier retrofit. We also provide a Free Second Opinion on any written estimate from another contractor - bring us their scope and we’ll read it with you. Call (737) 259-8352 for your exact written price.
Why Pflugerville Homeowners Call Topside Attic Insulation Pflugerville for Demilec Work

We’ve been in attics throughout Pflugerville’s growth corridors since 2016, and the regional heat load patterns in the Stone Hill Town Center area aren’t a surprise to our crew. Wes Okafor, our owner, trained in building systems technology at Kennedy-King College on Chicago’s South Side, where the curriculum drilled air-sealing fundamentals before insulation was even discussed. That sequence - sealed first, then insulated - is how we approach every Demilec job.
We publish before-and-after blower-door numbers on every applicable job, so you verify the performance change rather than taking our word. Our materials include Demilec, Icynene, and Reflectix systems, so we’re not locked into one manufacturer’s solution when another fits your cavity condition better. Calls are answered by a live person 24/7, and every job closes with a written warranty under our 365-Day Done Right Promise.
FAQs
Demilec’s residential warranty covers material defects in original application, but it does not cover shrinkage from foundation movement, moisture intrusion from roof leaks, or application errors by the original installer. We document the failure mode during our audit and can help you determine whether a manufacturer claim is viable, though we do not process claims on Demilec’s behalf. Call (737) 259-8352 and we’ll review what you’re seeing.
We can source OEM Demilec two-component kits for touch-up work where color match and chemical compatibility matter, but we also stock compatible third-party closed-cell and open-cell foams that meet the same ASTM E84 and ICC-ESR standards. We specify which material we’re proposing in your written scope, with the performance data sheet attached. The choice is yours, not ours by default.
Localized shrinkage or voids under 25 square feet are almost always cheaper to repair - typically $420-$680 versus $1,800+ for full removal. But if the foam is delaminated across multiple cavities, contains moisture, or shows degraded chemistry from off-gassing, removal becomes the cost-effective path because repairs would be temporary. We tell you which category you’re in during the audit, with photos.
Most audits are scheduled within 24-48 hours, and the on-site work takes 2-3 hours for a typical single-family home. Same-day service is often available for urgency situations - a pending home sale, for instance, or an insurance documentation deadline. Call (737) 259-8352 to check today’s availability; estimates are free and written.
You get a written report with your pre- and post-repair blower-door CFM50 numbers, dated thermal images with temperature callouts, moisture meter readings where applicable, a photo log of every cavity we opened or probed, and a written scope with flat pricing for any recommended work. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
