Icynene Home Energy Audit in San Antonio: What to Know First
An Icynene home energy audit in San Antonio typically runs $149 to $400 depending on home size and which tests you need, and most audits take two to three hours from setup to summary. We’re an independent Icynene service provider, not a manufacturer rep, which means our findings are honest about what’s working and what isn’t. If you own a home with Icynene spray foam insulation and your energy bills have crept up, or if you’re buying a house with Icynene already in the walls, this page tells you exactly how we evaluate it.
Call (866) 751-4428 and a live person answers, day or night. We’ll schedule your audit, walk you through what to expect, and give you a straight answer on whether you even need one.
How Icynene Products Fail, and How We Catch It in an Audit
Icynene makes good foam. But after years in San Antonio attics, we’ve seen every way it can underperform. Here’s what actually shows up in our audits:
- Icynene Classic (open-cell, light-density) shrinkage at the roofline. Open-cell foam can pull back from rafters as it ages, especially in attics that hit 140°F every summer. The gap might only be half an inch, but it lets conditioned air bleed straight through. During a thermal imaging inspection we catch those gaps as bright streaks along the roofline that most homeowners never see.
- Icynene ProSeal (closed-cell) losing adhesion on metal surfaces. Closed-cell foam bonds aggressively to wood but can separate from metal ductwork or steel beams over time. The cause is usually moisture or oil residue from installation. A blower door test will show the leak, and thermal imaging confirms where the foam has lifted.
- Uneven foam depth from the original install. We regularly audit Icynene jobs in San Antonio where the installer sprayed 3 inches in open areas but only 1 inch around wiring and plumbing penetrations. Code compliance doesn’t mean even coverage. Our insulation inspection measures actual depth at multiple points, not just what the invoice said.
- Duct leakage inside foam-sealed attics. Here’s the one most homeowners don’t expect: if your ducts run through an attic that was foam-sealed, any duct leak now dumps conditioned air into a partially sealed space instead of the house. A duct leakage test tells us if your Icynene is doing its job or if the ducts are undermining it.
- Rodent damage in foam. Rats and squirrels in San Antonio will tunnel through open-cell Icynene like it’s soft cheese. We’ve pulled foam back in Alamo Heights and Terrell Hills and found burrows running six feet through the insulation. A visual inspection with our cameras catches this fast, and it changes the repair recommendation entirely.
Our Icynene Home Energy Audit Process
- 1
You call, we talk. A live person answers. We ask about your home’s age, square footage, when the Icynene was installed, and what symptoms you’re noticing. We quote the audit price right then, no surprises.
- 2
We set the blower door. Our tech arrives in a uniform, introduces himself, and installs a calibrated blower door in your front door frame. This depressurizes the house and reveals exactly where air is moving through the envelope.
- 3
Thermal imaging walkthrough. With the blower door running, we scan walls, ceilings, attic, and crawl spaces with an infrared camera. This is where Icynene gaps, voids, and moisture issues declare themselves.
- 4
Duct leakage test. We pressurize your duct system separately and measure CFM loss. On Icynene homes in San Antonio this is non-negotiable, because foam-sealed attics make duct leaks more consequential, not less.
- 5
Insulation inspection and measurements. We check foam depth, adhesion, and any rodent or moisture damage. We document everything with photos.
- 6
You get a written summary and straight recommendation. No pressure, no upsell. If your Icynene is fine, we tell you. If it needs work, we quote it and back it with the Done Right Promise: if it’s not done right, we make it right.

FAQs
No. A diagnostic audit doesn’t alter or remove any foam, so your Icynene warranty stays intact. If we find a defect and you want it repaired, we’ll discuss warranty implications with you before any work begins.
Yes. We re-spray or fill voids with compatible foam products, and where the original Icynene has failed structurally, we’ll give you a straight answer on whether patching makes sense or if removal is the better long-term call.
In most cases within 2 to 4 business days. If you have an active issue like a rodent infestation or sudden energy spike, we’ll do our best to move you up. Call (866) 751-4428 and we’ll tell you what the schedule looks like.
For small voids, gaps, or localized damage, repair is almost always cheaper, usually under a few hundred dollars. Replacement only makes sense when the foam has widespread rodent damage, moisture saturation, or was installed too thin to begin with. Our audit tells you which path you’re on before you spend a dime.
The audit itself is the diagnostic. If it uncovers repair work, we provide a written quote at no extra charge, and we’ll honor a free second opinion if you want to compare against any written estimate from another company.
