Icynene Blown-In Insulation Nationwide

Icynene Blown-In Insulation in Boerne: What to Know First

We provide independent Icynene blown-in insulation service in Boerne, typically completing attic top-ups and dense-pack wall jobs within one business day of your call. Most Icynene-compatible blown-in jobs in a home this size run between $1,800 and $3,400 for cellulose or fiberglass attic work, with dense-pack wall insulation running higher depending on cavity access. We do not start any job without a written price and a written scope, both delivered before a crew member sets foot in your attic.

This page is for Icynene product owners in Boerne who need blown-in insulation added, topped up, or used to supplement an existing Icynene system. If you own a home with Icynene open-cell or closed-cell foam already in place and need additional blown-in coverage, call (830) 529-7780. A live person answers, 24/7.

How Icynene Products Fail - and How We Fix Them

• MD-R-200 series shrinkage in cathedral ceilings. The MD-R-200 open-cell line can pull away from rafter bays in Boerne’s heat-cycling climate, creating thermal bypass channels that blown-in cellulose is often called in to fill. We find the gaps with thermal imaging, air-seal the separation with compatible latex sealant, then blow GreenFiber cellulose to the correct settled depth so the R-value isn’t compromised by convection loops.
• LD-C-50 overspray into soffits blocking intake ventilation. Icynene’s LD-C-50 low-density open-cell foam, when oversprayed during original install, hardens over soffit vents and turns the attic into a passive solar collector. We remove the obstructing foam mechanically, restore the intake path, and blow Owens Corning fiberglass to maintain thermal separation without choking the ventilation that Boerne’s 95°F summer afternoons demand.
• Classic Series density loss in band joists. Older Icynene Classic installations in Hill Country homes sometimes settled below original density in critical floor-to-wall transitions. We dense-pack Rockwool or Johns Manville blown fiberglass into those cavities at 3.5 pounds per cubic foot, which restores the air barrier function without disturbing the remaining foam.
• Water-managed closed-cell (MD-C-200) trapping roof leaks. Icynene’s MD-C-200 closed-cell foam is an excellent vapor retarder, but in Boerne’s spring hail season it can mask a roof leak until the decking is compromised. When we encounter saturated foam during a blown-in top-up job, we document the moisture source, remove the affected foam, allow drying, and only then install new blown-in insulation with a proper vapor profile.
• Compatibility failures with retrofit blown-in over Icynene. Some contractors blow cellulose directly onto Icynene open-cell without checking for surface curing completeness, trapping isocyanate off-gassing and creating odor issues. We verify foam cure with a simple acetone swipe test, then use Knauf Ecose blown fiberglass when substrate conditions warrant a vapor-permeable overlay.

Our Icynene Blown-In Insulation Process

1. 1
   Call and scheduling. A live person answers. We book a diagnostic visit, and you receive a text when your technician is en route.
2. 2
   Site evaluation and blower-door baseline. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. In Boerne’s older homes near the Cibolo Nature Center, we’ve seen pre-work readings above 4,000 CFM50 before any insulation goes in.
3. 3
   Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No exceptions.
4. 4
   Air sealing first, then insulation. Seal the envelope first. Then fill it. We seal top plates, can lights, and penetrations before any blown-in product enters the space.
5. 5
   Material selection and installation. We match the blown-in product to your existing Icynene system - cellulose, fiberglass, or dense-pack - using OEM-compatible or quality aftermarket materials from our approved supplier list.
6. 6
   Post-work testing and documentation. We run a second blower-door test, photograph the completed work, and hand you the pressure-differential report in pascals plus the Documented Photo Record. The 365-Day Done Right Promise applies from that moment.

What Icynene Blown-In Insulation Costs in Boerne

These ranges reflect what we see in Boerne’s 2,000-3,500 square foot homes built between 1985 and 2020. Homes with complex rooflines, conditioned attic conversions, or active rodent issues fall outside these brackets until we see the space. Call (830) 529-7780 for a written estimate - estimates are free, and we provide a Free Second Opinion on any written estimate you’ve already received.

Why Boerne Homeowners Call Topside Attic Insulation Boerne for Icynene Work

We’ve sealed and insulated more than 9,000 homes since 2016, and the ones with existing Icynene foam require a different diagnostic approach than blank-slate attics. Wes Okafor trains our crews to read foam density, identify cure-state, and know when a blown-in retrofit will perform and when it will mask a deeper problem. We carry Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in means we specify what works with your existing system, not what a manufacturer requires us to sell.

Every applicable job leaves your house with before-and-after blower-door numbers on paper. The 365-Day Done Right Promise covers all completed work. Calls are answered by a live person, 24/7, and our technicians are background-checked and uniformed.
