Icynene Blown-In Insulation Nationwide

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

We provide independent Icynene blown-in insulation service in Converse, typically completing attic jobs in one day with a written price delivered before any work starts. Most Icynene top-up or replacement jobs in the area run between $1,800 and $4,200 depending on attic square footage, existing depth, and whether the air sealing has been addressed first. We’re not affiliated with or authorized by Icynene; we work on these systems as an independent service provider with no proprietary product lock-in.

This page is for Converse homeowners who already have Icynene insulation in their attic, walls, or crawl space and need to add blown-in material, replace degraded product, or correct a job that didn’t start with proper air sealing. If your home is in one of the ranch-style neighborhoods near Foster Road or the newer builds off FM 1518, the climate realities here, hot summers, mild winters, and sudden spring humidity spikes, affect how Icynene performs over time. Call (830) 420-0953 to schedule a free estimate with a written scope.

How Icynene Products Fail - and How We Fix Them

• Icynene LD-C-50 open-cell spray foam shrinkage at top plates. In Converse’s heat-cycling climate, this open-cell series can pull away from framing members after 7-10 years, creating a thermal bypass that makes any blown-in top-up ineffective. We remove the degraded sections, reseal with compatible foam, then blow in cellulose or fiberglass to the correct depth.
• Icynene MD-R-200 closed-cell moisture trapping in unvented attics. This medium-density closed-cell series is vapor-impermeable; when it’s applied too thick in Converse’s humid shoulder seasons, it can trap moisture against roof decking. We diagnose with infrared and moisture meters, remove compromised sections if needed, and specify blown-in fiberglass with proper venting rather than adding more impermeable foam.
• Icynene H2Foam Lite overspray into soffits blocking intake ventilation. This water-blown closed-cell product expands aggressively; we’ve found it blocking soffit vents in Converse homes where the original installer didn’t mask properly. We cut back the obstruction, restore intake airflow, then add blown-in insulation with baffles to prevent future wind washing.
• Icynene Classic Max settling in wall cavities originally dense-packed. Blown-in wall systems using this product can settle 15-20% over time in Converse’s wood-frame construction, leaving gaps at the top of stud bays. We drill and re-dense-pack with matching material, or switch to a stabilized cellulose if the homeowner prefers a different performance profile.
• Icynene product incompatibility with subsequent blown-in layers. Some Icynene formulations, particularly early-generation open-cell, don’t bond well with cellulose or fiberglass blown in later. We test a small section first, and if delamination occurs, we install a separation layer or remove the incompatible material rather than cover it and hope for the best.

Our Icynene Blown-In Insulation Process

1. 1
   Call and scheduling. A live person answers, 24/7. We book a diagnostic visit with a named technician; you get a text when they’re on the way.
2. 2
   Attic inspection and blower-door test. We pressurize the house to 50 pascals and record the CFM50 reading, then inspect the Icynene condition with infrared imaging. Wes Okafor still carries that dog-eared notebook of thermal bridge photos from past Converse jobs, useful for showing homeowners what we’re seeing in their attic.
3. 3
   Written price and scope. Before any work starts, you receive a flat price, written scope, and written warranty. Haven Standard Clause 1: no exceptions.
4. 4
   Air sealing first, then insulation. We seal top plates, can lights, and all penetrations before blowing anything in. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
5. 5
   Blown-in installation with material selection. We source from Icynene, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Demilec, and GreenFiber, choosing based on your existing system and performance goals, never pushing a proprietary product.
6. 6
   Post-work blower-door test and documentation. We run the pressurization test again, print the before-and-after comparison, and add the photos to your Documented Photo Record. You leave with the numbers in hand.

What Icynene Blown-In Insulation Costs in Converse

Most Icynene blown-in jobs in Converse fall in these ranges:

Prices move up if we find unsealed top-plate penetrations, the gap where walls meet the attic floor, common in Foster Road-era ranch homes, or if the existing Icynene has degraded and must be removed before new material goes in. We also provide a Free Second Opinion on any written estimate from another contractor. Call (830) 420-0953 for your written price, estimates are free.
