Icynene Spray Foam Insulation in Schertz: What to Know First
We provide independent Icynene spray foam insulation service in Schertz, typically completing diagnostic and repair calls same-day or next-day with a written price before any work starts. Most Icynene spray foam jobs in Schertz homes run between $1,800 and $4,500 depending on whether we’re addressing open-cell degradation in a 2018-era install or applying closed-cell to a rim joist in a newer build near the FM 3009 corridor. This page is for homeowners who need their Icynene system diagnosed correctly, repaired with warranty-safe practices, and documented with before-and-after blower-door numbers they can keep.

How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell) shrinkage from attic heat cycling. In Schertz, where attic temperatures routinely exceed 140°F from June through September, Classic Max installed before 2019 can pull away from framing members, creating thermal bypasses. We find this most often in the Sedona subdivision and similar 2015-2018 builds. Our fix: mechanical removal of detached foam, substrate reconditioning, and reapplication with proper lift thickness to prevent exotherm cracking. We document the gap pattern with thermal imaging and publish the blower-door delta.
- Icynene MD-R-200 (closed-cell) delamination from OSB roof decks. This moisture-cure product can release from roof sheathing when installed over damp substrate during Schertz’s spring humidity spikes. The symptom homeowners notice first: a “crinkling” sound in the attic during temperature swings. We test substrate moisture content with a pinned meter before any touch-up, then spot-repair with compatible closed-cell rather than full removal when the delamination is localized. Full deck recovery runs higher but we price both paths in writing.
- Icynene LD-C-50 (low-density open-cell) dusting and surface oxidation. The 0.5 pcf density makes this product vulnerable to UV and air movement degradation when the ignition barrier coating fails or was never applied to code. In Schertz, we see this where storage activity has worn the protective coating off exposed foam. We reapply a code-compliant ignition barrier after surface preparation, or recommend upgrading to a higher-density product if the application area sees regular occupancy.
- Rim joist applications with incomplete coverage. Icynene’s open-cell products in rim joist cavities must achieve full contact with all six sides to prevent condensation. Our thermal scans in Schertz crawl spaces regularly find voids behind plumbing chases where the original installer couldn’t access. We complete the seal with closed-cell for the rim joist proper, using Icynene-compatible chemistry, and provide depth-stick photos of every cavity.
- Garage ceiling Icynene installs with inadequate fire separation. Code in Schertz requires a thermal barrier between living space and foam in garage ceiling applications. We’ve found multiple cases where the original contractor used an intumescent coating rated for the wrong foam density. We source the correct barrier system, install to ICC-ESR documentation, and provide the homeowner with the product data sheet for their permit file.
Our Icynene Spray Foam Insulation Process

- 1
Call and schedule. A live person answers at (830) 402-5240, 24/7. We book a diagnostic window and text you when the technician is en route.
- 2
Blower-door test and thermal scan. We pressurize the house to measure CFM50 leakage, then run a thermal camera to locate Icynene failures. You get the starting number in writing.
- 3
Written price before any work starts. We specify OEM Icynene product or compatible aftermarket, the repair scope, and the warranty terms. No work begins until you have this document.
- 4
Air sealing first, then foam repair or reapplication. We seal top plates, can lights, and penetrations before touching the Icynene. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
- 5
Post-work blower-door test and photo documentation. We run the pressurization test again, deliver the CFM50 reduction in writing, and provide a Documented Photo Record of the completed work.
- 6
365-Day Done Right Promise activation. Your written warranty and scope go in the file. If it’s not done right, we make it right.
What Icynene Spray Foam Insulation Costs in Schertz
Most Icynene spray foam insulation jobs we handle in Schertz fall in these ranges:
| Job Type | Typical Range |
|---|---|
| Open-cell spot repair (shrinkage/dusting, under 200 sq ft) | $1,800 - $2,800 |
| Closed-cell rim joist completion (typical 1,500 sq ft home) | $2,400 - $3,600 |
| Roof deck delamination repair (partial, MD-R-200) | $2,800 - $4,200 |
| Full garage ceiling thermal barrier + foam correction | $3,200 - $4,500 |
What moves the price: accessibility (crawl space height, roof pitch), extent of degraded foam requiring mechanical removal versus spot repair, and whether the original install documentation is available to confirm product density and application thickness. We also handle Reflectix radiant barrier systems where they’re integrated with the Icynene assembly.

Why Schertz Homeowners Call Topside Attic Insulation Schertz for Icynene Work

We’ve been working the Schertz corridor for several years now, including jobs in the Sedona subdivision off FM 1518 where summer attic temps regularly push past 140°F before a single batt goes in. Wes Okafor built this operation on sequencing the work correctly: blower-door test first, air-sealing the top plates and penetrations second, blown-in or spray foam third. Every completed job comes with a printed thermal-imaging summary and a post-install depth-stick photo log so the homeowner has documentation, not just a receipt.
We’re an independent Icynene service provider, not a factory-authorized dealer, which means we source Icynene product when it’s the right fit and compatible alternatives when the job or timeline calls for it. Our materials list includes Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary lock-in. The 365-Day Done Right Promise applies to every job, backed by a written scope and written warranty delivered before anyone lifts a tool. Background-checked, uniformed technicians. Calls answered by a live person, 24/7.
FAQs
It depends on what product line was installed and whether the original contractor filed the warranty registration. Icynene’s system warranty typically requires application by a certified installer using specified equipment; our repairs are warranty-safe because we use Icynene-compatible chemistry and document substrate conditions, but we do not extend or assume the original manufacturer’s warranty. We provide our own 365-Day Done Right Promise on all workmanship. Call (830) 402-5240 and we’ll review your install documentation with you.
For common Icynene products - Classic Max, MD-R-200, LD-C-50 - we stock compatible material in our Schertz warehouse and can typically start within 24-48 hours. Specialty or discontinued Icynene formulations may require a 3-5 day order cycle. We’ll tell you exactly which product we have in stock and which we’d need to source when we deliver your written price. Call (830) 402-5240 for current availability.
Spot repair of localized shrinkage or delamination usually costs 40-60% less than full removal and reapplication. Full removal becomes the better value when the foam covers more than 30% of the envelope surface and shows systemic failure patterns - multiple shrinkage zones, widespread oxidation, or repeated moisture intrusion. We price both paths in writing so you can compare. Call (830) 402-5240 for a diagnostic and written estimate.
Yes, we match density and chemistry to the existing foam when the product is identifiable - we carry open-cell at 0.5 pcf and closed-cell at 2.0 pcf densities that interface correctly with Icynene’s typical specifications. When the original product tag is missing or the foam has degraded beyond recognition, we core-sample and test before specifying the repair material. Call (830) 402-5240 to schedule sampling.
Yes, we regularly address integrated assemblies where Reflectix was installed before or after Icynene foam. The sequencing matters: radiant barrier goes to the warm side, foam to the conditioned boundary, and we verify which layer is performing which function before modifying either. We’ve corrected multiple Schertz jobs where the original installer reversed the stack-up. Call (830) 402-5240 for a diagnostic.
