Icynene Spray Foam Insulation Nationwide

Icynene Spray Foam Insulation in Boerne: What to Know First

We provide independent Icynene spray foam insulation in Boerne, typically completing jobs in one to two days with a written price delivered before any work starts. Most Icynene repairs and upgrades in this market run between $1,200 and $3,800 depending on whether we’re addressing a localized failure or re-insulating a full attic or roof deck. This page is for homeowners who already have Icynene in their walls, attic, or rim joists and need a technician who understands how this specific product behaves in Hill Country conditions.

How Icynene Products Fail - and How We Fix Them

• Icynene Classic Max (open-cell) shrinkage from seasonal humidity swings. Boerne’s spring humidity spikes and dry winter spells cause Classic Max to pull away from studs and rafters, creating gaps that defeat the air barrier. We cut back the affected foam, re-seal the substrate with a compatible primer, and reapply to the original thickness. On a 2019 home near River Road, we found 3/8-inch gaps along the entire north roof deck after two hard winters.
• Icynene MD-R-200 (closed-cell) delamination from hot roof decks. When attic temperatures in Boerne hit 140°F for weeks at a time, the MD-R-200 can release from OSB sheathing, especially if the original installer skipped surface preparation. We mechanically remove the failed sections, abrade the substrate to bare wood, and reapply with a moisture-cure urethane bonding agent. The fix holds because we address the adhesion failure, not just the symptom.
• Icynene LD-C-50 (low-density open-cell) water staining from roof leaks. LD-C-50 is hydrophilic, meaning it wicks and holds water rather than shedding it. A small roof leak can saturate a large area, and once water-logged, the foam loses R-value and breeds mold. We remove the damaged foam back to dry substrate, treat any fungal growth, repair the roof penetration, and reinstall with a vapor-permeable assembly that lets the wall cavity dry to the interior.
• Icynene H2Foam Lite (water-blown open-cell) odor complaints from off-gassing. H2Foam Lite can retain amine catalyst odors if installed too thick in a single pass or if the substrate temperature was below manufacturer spec during application. We identify the source layer, remove it, and reapply in lifts per Icynene’s published pass-thickness limits. We also run a blower-door test after to confirm we’re not trapping residual odor in a sealed cavity.
• Rim joist failures in Icynene closed-cell applications. In Boerne’s older homes near the historic district, rim joists often sit below grade on one side and open to humid crawl space on the other. Icynene closed-cell applied too thin here cracks from thermal cycling. We remove the compromised foam, treat the wood for moisture content, and reinstall to a minimum 2-inch pass with proper lift timing. Seal the envelope first. Then fill it.

Our Icynene Spray Foam Insulation Process

1. 1
   Call and scheduling. A live person answers, or you can text. We schedule a site visit with a named technician and send a text when they’re en route.
2. 2
   Diagnostic inspection with photo documentation. We photograph the failure, measure moisture content in the substrate with a pinless meter, and identify the Icynene product line and original application date if possible.
3. 3
   Blower-door test (when applicable). For attic and roof-deck work, we run a pressurization reading to establish the baseline CFM50. This number tells us how much conditioned air the home is losing before we touch anything.
4. 4
   Written scope and price. We specify OEM Icynene material versus quality aftermarket equivalent, explain the trade-off, and deliver a flat price with warranty terms before any work starts. Haven Standard Clause 1: no exceptions.
5. 5
   Removal, prep, and reinstallation. We contain the work area, remove failed foam mechanically (never with solvents that compromise remaining foam), prep the substrate per manufacturer spec, and reinstall to the correct thickness in proper lifts.
6. 6
   Post-work verification and documentation. We run a second blower-door test where applicable, photograph the completed work, and deliver a printed report with before-and-after numbers. The homeowner keeps the photo record and pressure-differential report in pascals.

What Icynene Spray Foam Insulation Costs in Boerne

What moves the price: accessibility (steep roof decks or tight crawl spaces), extent of failed foam removal, whether the original substrate needs moisture remediation, and whether we’re matching existing Icynene or transitioning to a different product. We also service Reflectix systems and can advise when a hybrid assembly makes more sense than straight Icynene replacement. Every estimate is free, written, and delivered before any work starts.

Why Boerne Homeowners Call Topside Attic Insulation Boerne for Icynene Work

We’ve worked Icynene systems across the Hill Country since 2016, including a stretch of older homes near the Cibolo Nature Center where stack-effect air leakage was destroying cooling performance before insulation ever went in. Our technicians carry the full Icynene product knowledge base, but we’re not locked to any single brand, we source from Icynene, Demilec, and other manufacturers as the job demands. Every applicable job gets before-and-after blower-door numbers in writing. The 365-Day Done Right Promise covers all completed work, and our background-checked, uniformed crews arrive with a written scope and a named technician. Calls are answered by a live person, 24/7.
