Demilec Insulation Removal & Replacement Nationwide

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

We provide independent Demilec insulation removal and replacement in Schertz, typically completing most jobs in one to two days depending on attic size and contamination level. Most homeowners receive a written price before we lift a tool, and we do not start work without it. This page is for Schertz homeowners who have Demilec spray foam or hybrid insulation systems that need removal due to failure, contamination, or renovation needs. If your attic has Demilec Heatlok HFO Pro, Demilec Sealection 500, or an older Demilec Agribalance installation showing signs of degradation, we can assess it and give you a flat, written quote. Call (830) 402-5240 to schedule. Estimates are free.

How Demilec Products Fail - and How We Fix Them

• Heatlok HFO Pro shrinkage and pull-back from top plates. We’ve removed this closed-cell foam in Schertz homes, particularly in the Sedona subdivision off FM 1518, where summer attic temperatures exceed 140°F and accelerate thermal cycling. The foam contracts where it meets framing members, creating gaps that render the R-value meaningless. We cut out the failed sections, seal the top plates with compatible sealant, and replace with a system matched to the thermal envelope.
• Sealection 500 open-cell water absorption and weight gain. This water-blown open-cell foam can absorb moisture if the roof deck above it fails or if bathroom vents dump humid air into the attic. We’ve pulled saturated Sealection 500 that gained enough weight to stress drywall ceilings below. We remove the wet foam, identify and fix the moisture source, dry the cavity, and reinstall with proper vapor management.
• Agribalance odor retention in retrofit applications. The older Agribalance line, made with castor oil derivatives, can trap odors from rodent activity or previous smoke damage in a way that standard attic cleaning won’t resolve. We mechanically remove the foam, HEPA-vacuum the substrate, and apply an enzyme treatment before installing replacement insulation.
• Hybrid system delamination between Demilec spray foam and fiber insulation layers. Some Schertz builders installed Demilec as a flash-and-batt system with fiberglass batts over a thin foam layer. When the foam degrades, the batt sags and creates convective loops. We remove both layers, air-seal the deck and penetrations properly, and reinstall with a continuous insulation strategy.
• Improper initial installation depth leading to underperformance. We find Demilec jobs where the installer sprayed to pass visual inspection but missed the specified thickness, especially at eaves and around truss chords. We strip the inadequate foam, document the deficiency with depth-stick photos for the homeowner’s records, and reinstall to the correct thickness with thermal imaging verification.

Our Demilec Insulation Removal & Replacement Process

1. 1
   Call and scheduling. A live person answers at (830) 402-5240 24/7. We book an inspection, send a text with your technician’s name when they’re en route, and arrive on schedule under Haven Standard: Arrive on schedule.
2. 2
   Attic inspection and blower-door test. We pressurize the house to measure CFM50 - the single number showing how much conditioned air escapes through the envelope. Wes Okafor, who picked up building science fundamentals at Richard J. Daley College before two decades in attics, directs the crew to identify whether the Demilec failure is isolated or systemic.
3. 3
   Written price and scope. We deliver a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions. If you have a competing quote, we provide a Free Second Opinion and read it with you.
4. 4
   Removal and substrate preparation. We mechanically remove the failed Demilec product, HEPA-vacuum the cavity, and treat for odor or biological contamination if needed. Every step is photographed for the Documented Photo Record you receive.
5. 5
   Air sealing and replacement installation. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it. We seal top plates, can lights, and penetrations, then install replacement insulation - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, or GreenFiber, whichever fits your envelope strategy. No proprietary lock-in.
6. 6
   Post-work verification and documentation. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers so you can verify the air-sealing result. You walk away with a printed thermal-imaging summary, post-install depth-stick photo log, and written warranty under our 365-Day Done Right Promise.

What Demilec Insulation Removal & Replacement Costs in Schertz

Most partial Demilec removal and replacement jobs in Schertz run between $2,800 and $5,400 for a typical 1,800-2,400 square foot home. Full attic strip-outs with contaminated insulation removal range from $4,200 to $7,800 depending on square footage, accessibility, and whether rodent proofing or deck repair is needed.

What moves the price: attic square footage, roof pitch and accessibility, presence of HVAC equipment that must be worked around, contamination level requiring PPE and disposal protocols, and whether the roof deck needs repair before replacement. We also service Reflectix radiant barrier systems if your home has a mixed insulation strategy. Call (830) 402-5240 for an exact quote - estimates are free.
