Demilec Home Energy Audit in Georgetown: What to Know First
A Demilec home energy audit in Georgetown typically runs $280-$520 for a full envelope assessment with blower-door test, thermal imaging, and duct-leakage measurement; most audits are scheduled within 48 hours and the written report is delivered same day. We are an independent Demilec service provider, not affiliated with the manufacturer, which means we test what is actually in your attic without any product bias. If you own a Demilec spray-foam system in a Georgetown home built between 2015 and 2022, this page is for you. Call (254) 970-2136 to book a free estimate or bring us a competing written quote for a free second opinion.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO High Lift shrinkage in Sun City Georgetown attics. The HFO blowing agent can lose expansion ratio in sustained attic temperatures above 135°F, common in Georgetown’s west-facing roofs from June through September. We find 15-20% thickness loss in five-year-old installs, which drops the effective R-value below the labeled performance. Our fix: thermal imaging to map the shrinkage zones, selective removal, and reapplication with corrected lift calculations for the actual attic conditions.
- Heatlok XT adhesive failure on OSB roof decks with high moisture drive. In homes near the San Gabriel River corridor where nighttime humidity spikes above 75%, we’ve seen XT pull away from sheathing at the ridge, creating convective loops that bypass the foam entirely. We diagnose this with smoke-pencil testing during the blower-door run, then cut back the failed sections and re-bond using a vapor-adjusted primer sequence.
- Demilec 500 open-cell dusting in unvented cathedral ceilings. The 500 series at low application thickness can develop a friable surface that sheds particulates into conditioned space, especially where installers rushed the pass pattern. We collect samples, measure actual density with a core test, and specify either a protective coating or targeted re-spray depending on the degradation depth.
- SEALECTION Agribalance odor retention in homes with prior rodent activity. The bio-based polyol can trap organic compounds from attic soilage that other foams would vent; owners report a persistent “sweet” smell that thermal imaging alone won’t explain. We run a VOC screening as part of the audit, map the contaminated zones, and specify removal plus encapsulation with a vapor-barrier overlay where the substrate is compromised.
- Demilec two-component mixing errors from 2016-2019 installs. Georgetown’s building boom during those years included crews new to plural-component equipment; off-ratio foam cures soft or over-dense, failing ASTM D1622 density standards. We core-test suspect areas, document the variance, and specify either localized removal or full redecking depending on the percentage of compromised surface area.
Our Demilec Home Energy Audit Process

- 1
Call intake with a live person. Calls to (254) 970-2136 are answered 24/7 by a human who schedules your audit and texts you a named technician profile before arrival.
- 2
Pre-job documentation. We photograph your existing Demilec install from multiple angles, record the labeled product line if visible, and pull any permit history from Williamson County to verify original application thickness claims.
- 3
Blower-door test and thermal imaging. The blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - establishes the baseline CFM50. We run FLIR scans simultaneously to locate thermal bypasses the foam was supposed to eliminate.
- 4
Duct-leakage test and insulation inspection. We pressurize your duct system to 25 Pascals and measure leakage to outside; then we core-test or probe-map the Demilec to verify actual versus specified R-value and density.
- 5
Written scope and pricing. Before any work starts, you receive a flat price, written scope, and written warranty - Haven Standard Clause 1. No exceptions.
- 6
Post-work verification and documentation. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers, plus thermal images and a Documented Photo Record, so you can verify the result we measured.
Before
AfterWhat Demilec Home Energy Audit Costs in Georgetown
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Basic audit (blower-door + thermal imaging) | $280-$380 | Home size, attic accessibility, number of HVAC zones |
| Full audit with duct-leakage test | $380-$520 | Duct system complexity, need for register sealing |
| Core density testing (per sample) | $45-$75 | Lab turnaround, location access difficulty |
| VOC screening for odor complaints | $120-$180 | Number of sample points, compound panel |
| Written remediation scope | Included | Always included with any paid audit |
Homes in Georgetown’s older neighborhoods near downtown - pre-1990 construction with multiple additions - tend toward the upper end due to envelope complexity. Newer builds in Teravista or Rancho Sienna audit faster but often reveal more dramatic duct-leakage numbers because the Demilec was installed before final air-sealing was complete.

Why Georgetown Homeowners Call Topside Attic Insulation Georgetown for Demilec Work

We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. Our technicians are background-checked, uniformed, and trained on Demilec’s specific failure patterns - not generic spray-foam troubleshooting. The 365-Day Done Right Promise applies to all completed work: if it’s not done right, we make it right, backed by the written scope and warranty delivered before anyone lifted a tool.
We also service Reflectix and other major brands, so our recommendations aren’t locked to any single manufacturer’s product line. Seal the holes first. Then we talk about R-value. That’s the Haven Standard, and it’s how Wes Okafor has run every job since he started this business.
FAQs
No - manufacturer warranties cover product defect, not who performed the diagnostic. We document our testing methodology and provide photos that satisfy most warranty claim requirements, though we cannot file claims on your behalf as an independent service provider. If you’re preparing a warranty submission, call (254) 970-2136 and we’ll format the report to match their documentation standards.
We source OEM Demilec products when the repair must match existing chemistry for compatibility, particularly with Heatlok HFO and XT series where mixing brands creates adhesion risk. For encapsulation or overlay work where the original foam remains in place, we may specify compatible third-party products with equivalent density and permeance ratings - always disclosed in the written scope with the reason.
Replace when core density tests show more than 30% of the surface area is off-spec, or when VOC screening indicates substrate contamination that will outgas through any overlay. Repair is viable for localized shrinkage, adhesive failure under 10% of surface area, or dusting limited to accessible zones. We give you both numbers and a recommendation, not a sales pitch - call (254) 970-2136 for a free estimate.
Most Georgetown appointments are available within 48 hours; same-day service is sometimes possible for active moisture or odor issues. We do not use callback windows measured in business days - a live person answers and schedules. For thermal imaging accuracy, we prefer to test when the attic has had at least four hours of sun exposure, which in Georgetown means morning appointments from April through October.
You receive the written scope, flat price, and warranty before work starts; after completion, a Documented Photo Record with dated thermal images, blower-door CFM50 readings before and after any air-sealing work, duct-leakage CFM25 numbers, and any core density or VOC lab results. This is standard on every job, not available on request.
