Icynene Blown In Insulation Nationwide

Icynene Blown In Insulation in San Antonio: What to Know First

Icynene blown in insulation work in San Antonio typically runs between $1.50 and $4.00 per square foot depending on the cavity depth, existing material condition, and whether we’re topping off an old attic or starting from bare decking. Most jobs in the San Antonio market are completed in a single day, and every quote comes to you in writing before any material hits the attic floor. We are an independent Icynene service provider, not a manufacturer-authorized dealer, which means we answer to you and the work, not a corporate program.

This page is for San Antonio homeowners who already have Icynene in their attic or walls and need blown in insulation repair, removal, or a performance upgrade. If your attic keeps getting hotter despite the Icynene being in place, or you’ve noticed settling and gaps around the eaves, the information below is built for that exact situation. Call (361) 213-9499 and you’ll get a live person who can schedule a look at your attic.

How Icynene Products Fail – and How We Fix Them

Icynene makes quality products, but San Antonio’s heat and humidity expose weaknesses that the manufacturer’s brochure won’t tell you about. Here’s what we see across San Antonio attics and how we address it:

• Icynene Classic settling and shrinking. The original open-cell Classic formula can shrink slightly at the edges over a decade of San Antonio’s 100-degree attic cycles. When it pulls away from roof decking or top plates, you get a thermal bypass at the exact perimeter where hot air sneaks in. We remove the compromised section cleanly and blow in a compatible open-cell fill or top off with loose fiberglass to close the gap.
• Icynene ProSeal and ProSeal LE compression at the eaves. In older San Antonio homes with tight soffit framing, the ProSeal line can get compressed during original installation and never fully recover its advertised R-value. The symptom is simple: rooms near exterior walls run 5 to 8 degrees warmer than the rest of the house. We identify the compressed bays, remove the underperforming foam, and re-insulate those cavities properly.
• Icynene Lite’s UV exposure problem. Icynene Lite is not UV-stable at the roofline, and in San Antonio attics where gable vents or roof turbines let light in, the exposed top layer breaks down into a chalky dust. That dust doesn’t insulate. We remove the degraded material and either re-cover with a UV-stable product or blow in a protective loose-fill layer that shields the remaining foam.
• Retrofit misalignment around can lights and bath fans. We regularly find Icynene sprayed right up against recessed light housings that aren’t IC-rated. Fiberglass and foam against a non-IC can is a fire risk, and in San Antonio homes built before 1990, those fixtures are common. We clear the required air gap around each fixture and blow in insulation that keeps the thermal barrier without creating a hazard.
• Blown-in over failed Icynene in accessible attics. Some San Antonio homeowners bought houses where a previous owner blew loose fiberglass over already-settled Icynene. The top layer looks fine from the hatch, but underneath the foam has detached from the decking. We probe below the loose fill, confirm whether the Icynene is still adhering, and only then decide if we’re removing everything or adding more.

Our Icynene Blown In Insulation Process

Here’s exactly what happens on an Icynene blown in insulation job with us in San Antonio:

1. 1
   You call and get a live person. No voicemail tree. We schedule a time that works for you, and we send you the name and photo of the technician who will arrive, before they ring the doorbell.
2. 2
   The tech shows up in a marked uniform with a photo ID badge. Our technicians are background-checked and identity-verified to the Threshold Standard. If someone else arrives, the visit is on us.
3. 3
   We inspect the existing Icynene. We check adhesion at the decking, look for settling at the eaves, probe for compression, and measure the current R-value in multiple spots, not just the one closest to the hatch.
4. 4
   You get a written price. Before any work starts, we put a number in writing covering all labor and materials. No surprise line items after the fact, no “we discovered extra problems” phone calls mid-job.
5. 5
   We do the work. That means removing failed material where needed, blow in the right product for your cavity depth, hit the target R-value for San Antonio’s climate zone, and clean up the attic like we were never there except the insulation is now right.
6. 6
   We walk you through it and hand you the guarantee. Every job gets our 365-Day Done Right Promise in writing, covering labor and materials. If something fails within a year, we come back and fix it free.
