Demilec Insulation Removal & Replacement Nationwide

Demilec Insulation Removal & Replacement in Georgetown: What to Know First

We provide independent Demilec insulation removal & replacement in Georgetown, typically completing residential jobs in one to two days with a written price delivered before any work starts. Most Demilec systems we encounter in Georgetown homes are the Heatlok HFO Pro or Heatlok Soya lines installed during the 2015-2022 building boom, and our process begins with documented thermal imaging and air-leakage testing, not with a truck full of new batts. If you’re seeing sagging foam, off-gassing odors, or insulation that never delivered the promised R-value, call (254) 970-2136 for a free estimate with a written scope.

How Demilec Products Fail - and How We Fix Them

• Heatlok HFO Pro shrinkage in unconditioned Georgetown attics. The HFO blowing agent can contract 8-12% when installed in attic temperatures that regularly exceed 135°F from June through September. We’ve pulled Heatlok HFO Pro that separated from roof decks in Sun City Georgetown homes, creating convection loops that bypass the foam entirely. We remove the failed foam mechanically, verify substrate moisture content with a pin meter, then reinstall only after the attic is properly air-sealed and ventilated.
• Heatlok Soya density inconsistencies in thick-lift applications. Demilec’s Soya line is marketed as a single-pass product, but applicators in the Georgetown area often exceeded recommended lift thickness during the 2018-2020 rush. The core remains under-cured, trapping isocyanate odors and producing a cheese-like texture that crumbles during removal. We section-cut these lifts, remove them with controlled abrasion, and document odor levels with a photoionization detector before any replacement begins.
• Demilec open-cell (Icynene-branded) water absorption in river-corridor homes. Homes near the San Gabriel River with elevated humidity sometimes show open-cell Demilec weighing in at 3-5x its original mass. Saturated foam loses structural integrity and breeds mold on the substrate. We remove it with HEPA-contained extraction, treat the deck with an EPA-registered antimicrobial, and specify closed-cell replacement for below-deck applications.
• Demilec retrofit jobs installed over unsealed top plates. This isn’t a product defect, it’s an installation failure we see repeatedly on Demilec jobs done by crews who skipped the air-sealing step. The foam bridges the plate but doesn’t seal it, so stack effect pulls conditioned air straight past the insulation. We remove the compromised sections, seal every top plate and penetration with single-component foam, then reinstall. Seal the holes first. Then we talk about R-value.
• Demilec foam degradation from rodent activity in older Georgetown subdivisions. In neighborhoods like Serenada and parts of Georgetown Village, roof rat populations have increased since 2019. Rodents tunnel through Demilec’s softer open-cell formulations, compressing them and leaving contamination that can’t be surface-cleaned. We remove the affected foam, rodent-proof with galvanized hardware cloth at all entry points, and replace with material appropriate to the space.

Our Demilec Insulation Removal & Replacement Process

1. 1
   Call and scheduling. A live person answers 24/7. We schedule a site visit in Georgetown, typically within 48 hours. You receive a text with your technician’s name when they’re en route.
2. 2
   Diagnostics and documentation. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - plus thermal imaging and moisture mapping. Every finding is photographed and logged.
3. 3
   Written scope and price. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions. We also offer a Free Second Opinion on any written estimate you’ve already received.
4. 4
   Controlled removal. Demilec foam comes out with mechanical abrasion, thermal softening, or chemical release agents depending on the substrate and product line. HEPA containment runs continuously. We dispose per Texas Commission on Environmental Quality guidelines.
5. 5
   Substrate preparation and air sealing. Every penetration, top plate, and can light gets sealed before replacement begins. We re-run the blower-door to establish a baseline.
6. 6
   Replacement, testing, and handoff. New insulation goes in, we run final blower-door and thermal imaging, and you receive a Documented Photo Record with before-and-after numbers. The 365-Day Done Right Promise applies from that moment.

What Demilec Insulation Removal & Replacement Costs in Georgetown

Most Demilec removal and replacement jobs in Georgetown homes run between $3,800 and $8,500, with the majority falling in the $4,500-$6,200 range for attics under 2,500 square feet. What moves the price:

• Accessibility: Attics with 14-inch clearance or less add labor hours for manual removal versus walkable spaces.
• Product line: Heatlok HFO Pro’s adhesion to OSB requires more aggressive removal than Soya’s softer cure.
• Contamination level: Rodent-affected foam requires PPE upgrades, antimicrobial treatment, and sometimes substrate repair.
• Replacement material: Closed-cell spray foam runs higher per board foot than blown-in fiberglass or Rockwool.

We also service Reflectix systems and can quote hybrid approaches. Call (254) 970-2136 for an exact quote - estimates are free, and the written price arrives before any work starts.

Why Georgetown Homeowners Call Topside Attic Insulation Georgetown for Demilec Work

We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve removed Demilec from attics across Georgetown’s building eras - from 1980s ranch homes near Southwestern University to new construction in Wolf Ranch that didn’t perform as specified. Wes Okafor and our crew have worked attics from Sun City Georgetown to homes backing up to the San Gabriel River corridor, and we publish before-and-after blower-door numbers on every applicable job so you can verify the air-sealing result you paid for. Background-checked, uniformed technicians. Live person on the phone. No voicemail loops. No callback windows measured in business days.
