Demilec Blown-In Insulation Nationwide

Demilec Blown-In Insulation in Converse: What to Know First

We provide independent Demilec blown-in insulation service in Converse, TX, with most attic jobs completed in one day and pricing put in writing before any work starts. A typical blown-in top-up or full replacement on a 1,800-square-foot Converse ranch runs between $1,800 and $3,400, depending on existing depth and how much air sealing the top plates need first. We don’t start blowing insulation until the attic floor is sealed, and we prove the result with before-and-after blower-door numbers. This page is for Demilec owners in Converse who want to know why their insulation isn’t performing, what fixing it actually costs, and who’ll show up to do the work.

How Demilec Products Fail - and How We Fix Them

• Demilec SEALECTION AgriBalance settled below labeled R-value in Converse attics. This open-cell spray foam hybrid was sometimes topped with blown-in fiberglass as a cost-saving measure by previous installers, and the density mismatch causes the loose fill to migrate away from eaves during our summer heat cycles. We remove the incompatible layer, re-establish proper depth at the perimeter, and match the replacement material to the original AgriBalance spec sheet.
• Demilec Heatlok HFO High Lift develops thermal bridging where blown-in was added over unsealed top plates. The high-lift chemistry creates an excellent air barrier at the roof deck, but homeowners often assume the attic floor doesn’t matter. Conditioned air escapes through wall-top gaps, and the blown-in cellulose or fiberglass becomes a filter, not insulation. We seal every top plate and penetration with fire-rated caulk and foam before touching the blower hose.
• Demilec 500 open-cell shrinks away from studs in wall cavities originally dense-packed with blown-in. This shows up as cold stripes on infrared during our winter audits in Converse homes near FM 1976. The shrinkage is usually 5-8%, enough to break the thermal boundary. We diagnose with a borescope, then dense-pack the cavity with matching blown-in cellulose after stabilizing the existing foam.
• Demilec Eco-Pur spray foam off-gassed and degraded adjacent blown-in fiberglass in hot attic conditions. The chemical interaction isn’t common, but we’ve found it three times in Converse homes built 2018-2021 where both products were used in the same envelope. We remove the contaminated fill, ventilate the space per manufacturer protocol, and reinstall with a physical barrier between dissimilar materials.
• Demilec SEALECTION 500 lost adhesion on ductwork wrapped with blown-in for sound attenuation. The weight of the loose fill, especially when disturbed by rodent activity in older Converse neighborhoods like Live Oak Corridor, pulls the foam from flex duct. We re-secure with mechanical fasteners, replace the blown-in with a lighter stabilized cellulose, and rodent-proof the chase while we’re there.

Our Demilec Blown-In Insulation Process

1. 1
   Call and schedule. A live person answers (830) 420-0953 24/7. We book a diagnostic visit with a written price commitment.
2. 2
   Attic inspection and blower-door test. We pressurize the house to 50 pascals and record the CFM50 reading - the single number that tells us how much conditioned air is escaping. Wes Okafor checks for Demilec product labels, installation dates, and any visible degradation.
3. 3
   Air sealing first. Every top plate, can light, wire penetration, and chimney chase gets sealed with fire-rated materials. We never blow insulation over an unsealed attic floor. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
4. 4
   Material selection and written price. We match blown-in cellulose or fiberglass to the existing Demilec product’s thermal and moisture properties. You get the scope, the price, and the warranty in writing before the blower starts.
5. 5
   Installation and documentation. The crew blows to labeled depth, verifies coverage with depth markers, and photographs the completed work. We run the blower-door test again and print the before-and-after report.
6. 6
   Cleanup and 365-Day Done Right Promise. We haul out debris, leave the attic access sealed properly, and activate the written warranty. If it’s not done right, we make it right.
