Demilec Insulation Removal & Replacement in Pflugerville: What to Know First
We provide independent Demilec insulation removal and replacement in Pflugerville, typically completing attic jobs in one to two days with a written price locked in before any work starts. Most Demilec removal and replacement projects in this market run between $2,800 and $6,500 depending on square footage, contamination level, and whether the existing foam needs full extraction or targeted remediation. This page is for homeowners in Pflugerville who have Demilec spray foam or hybrid insulation in their attic, walls, or crawl space and need it removed safely, replaced with a documented performance improvement, and backed by a written warranty. Call us at (737) 259-8352 for a free estimate with a written scope.
How Demilec Products Fail - and How We Fix Them
- Demilec Heatlok XT shrinks and pulls from studs in Pflugerville’s 100°F+ attics. The closed-cell foam was formulated for broader climate zones, and the thermal cycling in Texas attics causes it to separate from framing members after 8-12 years. We find this most often in the Blackhawk and Avalon communities where builders spec’d it heavily in 2012-2016. Our fix: full mechanical removal down to substrate, then reinstallation with a product rated for our specific heat-load zone, with top-plate air sealing completed first.
- Demilec Heatlok HFO High Lift develops odor issues when installed too thick in a single pass. The HFO blowing agent can trap exothermic heat during a hot-lift application, creating a persistent chemical smell that off-gasses for months. We’ve pulled this from three homes near Stone Hill Town Center where the original crew chased R-value in one pass instead of building lift-cured layers. Our fix: controlled-thickness removal, substrate verification, and replacement with a lift-cured protocol that never exceeds manufacturer pass thickness.
- Demilec Sealection 500 degrades when exposed to UV in attic gable vents or unsealed can-light housings. This open-cell foam yellows, powders, and loses adhesion when sunlight hits it, which happens in Pflugerville homes where attic ventilation was retrofitted after the original install. Our fix: removal of degraded sections, installation of sealed LED housings or baffles as needed, then replacement foam with UV-stable facing where light exposure is unavoidable.
- Demilec Agribalance absorbs moisture in crawl spaces with seasonal humidity swings. The bio-based content makes it more hygroscopic than petroleum-based foams, and Pflugerville’s spring humidity spikes can push moisture content past 15% in unencapsulated crawls. We see this in older homes near downtown where perimeter drainage is marginal. Our fix: full removal, vapor barrier installation or encapsulation, then replacement with a closed-cell product or hybrid system appropriate for the moisture environment.
- Demilec foam installed over unsealed top plates creates a thermal bypass that looks like foam failure. The foam itself is intact, but conditioned air leaks around it through gaps at wall-top intersections. Homeowners feel drafts and blame the Demilec. Our fix: targeted removal at bypass zones, proper air sealing of top plates and penetrations with gasketed boxes or foam, then patching with compatible material. The blower-door test - a pressurization measurement that shows, in one number, how much air the building envelope is losing - proves the fix before we leave.
Our Demilec Insulation Removal & Replacement Process

- 1
Site visit and written scope. We inspect the Demilec installation, document degradation patterns with photos, and test for contaminants. You get a flat price and written scope before any work starts - Haven Standard Clause 1.
- 2
Blower-door baseline. On applicable jobs, we run a pre-removal pressurization test to quantify how much air the house is losing with the current insulation in place.
- 3
Controlled removal. We mechanically extract the Demilec foam using specialized cutting and vacuum equipment, separating recyclable material from contaminated waste. Substrate condition is photographed at every stage.
- 4
Air sealing before reinstallation. Top plates, can lights, penetrations, and bypasses are sealed. We never blow new insulation over an unsealed attic floor - in that order, always.
- 5
Replacement with documented performance. We install replacement insulation from our multi-brand inventory - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, or GreenFiber - selected for your specific assembly and climate load. A post-work blower-door test provides before-and-after CFM50 numbers.
- 6
Cleanup, photo record, and warranty delivery. You receive a Documented Photo Record on Every Visit, the written warranty, and our 365-Day Done Right Promise - if it’s not done right, we make it right.
Before
AfterWhat Demilec Insulation Removal & Replacement Costs in Pflugerville
| Scenario | Typical Range |
|---|---|
| Partial Demilec removal (targeted remediation, under 500 sq ft) | $2,800 - $4,200 |
| Full attic Demilec removal and replacement, 1,000-1,500 sq ft | $4,500 - $6,500 |
| Crawl space Demilec removal with vapor barrier installation | $3,800 - $5,800 |
| Contaminated insulation removal (rodent, mold, moisture) with replacement | $5,200 - $8,500 |
Price moves with accessibility (steep pitch, limited attic scuttle), contamination level (hazmat handling adds labor), and whether the original Demilec was applied in a condition that damaged substrate.

Why Pflugerville Homeowners Call Topside Attic Insulation Pflugerville for Demilec Work

We’ve been in and out of attics throughout Pflugerville’s Stone Hill Town Center corridor often enough that the regional heat load patterns are not a surprise to us. Wes Okafor, who leads our crew, trained in building systems technology at Kennedy-King College on Chicago’s South Side, where instructors drilled air-sealing fundamentals before insulation was ever discussed. That sequence - sealed first, then insulated - is how we still operate. We are an independent Demilec service provider, not a factory-authorized dealer, which means we source replacement materials without product lock-in: Demilec when it fits, Reflectix or another brand when it does not. Every job closes with a written warranty, a Documented Photo Record, and, on applicable work, before-and-after blower-door numbers you can hold in your hand. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
FAQs
The original Demilec warranty typically covers material defect and original installation workmanship, not subsequent modifications by an independent service provider. As an independent Demilec service provider, our 365-Day Done Right Promise covers our removal and replacement workmanship specifically. We document substrate condition before we start so warranty questions have a clear baseline. Call (737) 259-8352 and we will review your original paperwork with you.
We can source Demilec products when they are the right fit for the assembly and climate load, but we are not locked to any single brand. Our inventory includes Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. We select based on what the house needs, not what we are contracted to push. The written scope names the specific product before work starts.
Targeted repair is cheaper when the failure is isolated - a single lifted section, a small UV-degraded zone near a gable vent. Full replacement is the better value when shrinkage, odor, or moisture degradation is widespread, because patchwork over failing substrate usually needs redoing within two years. We inspect, photograph, and tell you which category you’re in before you spend anything. Call (737) 259-8352 for a free estimate.
Most residential jobs are one to two days: removal and air sealing on day one, replacement and testing on day two. Contaminated jobs requiring hazmat protocol add a day for clearance testing. We answer calls with a live person 24/7 and schedule within a window that works for you - no voicemail loops, no callback windows measured in business days.
You receive a written scope, a written warranty, a Documented Photo Record of substrate condition and completed work, and on applicable jobs, before-and-after blower-door readings with actual CFM50 numbers. This is standard on every job, not available on request. Haven Standard: Have it in writing.
