Icynene Spray Foam Insulation in Converse: What to Know First
We provide independent Icynene spray foam insulation service in Converse, typically scheduling within 24-48 hours and completing most jobs in a single visit. Every job starts with a written price before any work starts, and you’ll receive a Documented Photo Record when we leave. Most Icynene spray foam insulation repairs in Converse run between $280 and $650 depending on the series and the extent of the envelope failure. This page is for homeowners who already have Icynene spray foam in their attic, walls, or rim joists and need it diagnosed, repaired, or supplemented by a crew that understands the material’s specific behavior in Bexar County’s heat and humidity cycles. Call (830) 420-0953 to schedule a free estimate, or text us if that’s easier.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell) shrinkage from seasonal humidity swings. Converse sits in a zone where attic temperatures hit 140°F in July and humidity spikes during spring storms. Classic Max can pull away from framing members over time, creating gaps at the stud bay perimeter. We cut back the separated foam, re-prime the substrate with Icynene-compatible adhesive, and reapply to the original thickness. On every job we run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - before and after, so you see the CFM50 drop.
- Icynene MD-R-200 (medium-density closed-cell) thermal drift from UV exposure in vented attics. When roof deck foam is left unprotected in a partially vented Converse attic, Texas sun degrades the upper surface even through soffit ventilation. The R-value doesn’t fall off a cliff, but the surface becomes friable and creates dust. We assess the depth, remove the degraded layer if it’s more than ¼ inch, and coat with an approved latex intumescent or install a rigid thermal barrier to code. We document the before-and-after condition in your photo record.
- Icynene LD-C-50 (low-density open-cell) water staining from roof leaks that travel through the foam matrix. Open-cell is vapor-permeable, which is the point, but it also wicks water laterally across a bay when a shingle fails. In Converse, we see this most on homes near FM 78 where wind-driven rain gets past ridge vents. We don’t just patch the roof and walk away; we remove the water-affected foam, dry the cavity with directed airflow, treat for any microbial growth, and reinstall to match the original density. The new foam bonds chemically to the old if the substrate is properly prepared.
- Icynene H2Foam Lite (water-blown open-cell) odor complaints from off-gassing in sealed cathedral ceilings. This series is popular in newer Converse builds with conditioned attic schemes, but improper mixing ratios during original install can leave residual amines that activate when the roof deck hits peak summer temperature. We identify the affected bays with boroscope inspection, remove and reapply with fresh material at the specified 4.5-inch minimum depth, and verify with a post-installation VOC screening. Wes Okafor keeps a dog-eared notebook of job photos on his phone - not for marketing, just because a picture of a thermal bridge caught on infrared is easier to explain than a paragraph.
- Icynene closed-cell at rim joists in pier-and-beam homes near Converse’s older neighborhoods. The freeze-thaw cycle of 2021 stressed a lot of Bexar County rim joist foam, and closed-cell can delaminate from concrete block when the bond line sees repeated expansion and contraction. We grind back to sound substrate, apply a masonry-compatible primer, and reinstall at 2-3 inches to restore the air barrier and the structural rigidity that closed-cell provides at the foundation perimeter. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
Our Icynene Spray Foam Insulation Process
- 1
Call or text (830) 420-0953. A live person answers, 24/7. We schedule a site visit, usually within 24-48 hours in Converse.
- 2
On-site diagnosis with thermal imaging and boroscope. We identify the Icynene series, map the failure, and check for contributing factors like roof leaks, HVAC duct leakage, or missing air barriers. You get a written price before any work starts, always.
- 3
Parts and materials decision. We use OEM Icynene material when the repair must match existing density and chemistry exactly. For certain applications, quality-compatible aftermarket foams from our approved suppliers perform identically at lower cost, and we’ll explain which applies to your job. We do not claim exclusive or preferred status with any manufacturer.
- 4
Prep, removal, and reinstallation. We isolate the work area, remove failed or degraded foam mechanically, prep the substrate per Icynene’s adhesion requirements, and apply new material to the specified thickness. Air sealing of top plates, penetrations, and junctions happens before any new insulation goes in.
- 5
Blower-door verification and documentation. On applicable jobs, we run the blower-door test before and after, print the CFM50 readings, and add them to your Documented Photo Record. You leave with a written scope, a written warranty, and the numbers that prove the envelope tightened.
- 6
365-Day Done Right Promise follow-up. If anything isn’t right, we make it right. The promise is in writing before we start.

FAQs
No, proper repair by a qualified insulation contractor does not void Icynene’s material warranty, though the original installation warranty may have time limits we can review with you. As an independent Icynene service provider, we document our repairs with photos and material batch records so any future warranty claim has support. Call (830) 420-0953 if you need help locating your original install documentation.
Yes, we stock or source the specific Icynene series used in your home - Classic Max, MD-R-200, H2Foam Lite, or LD-C-50 - and we verify density and adhesion compatibility before application. When a series has been discontinued, we specify the closest current equivalent and explain the performance difference in writing. Bring us a competing quote and we’ll read it with you.
Localized failure almost always costs less to repair than full removal, which runs $2.50-$4.00 per square foot in Converse for open-cell and higher for closed-cell. We recommend full removal only when the foam is extensively water-damaged, chemically compromised, or applied so far below specification that repair is impractical. We’ll show you the boroscope footage and give you both numbers.
Most Icynene repairs are scheduled within 24-48 hours, and emergency situations - active roof leaks traveling through foam, exposed electrical in contact with degraded material - get same-day response. A live person answers (830) 420-0953 24/7, no voicemail loops.
You receive a written scope of work, a written warranty, a Documented Photo Record of the repair area, and on applicable jobs, before-and-after blower-door readings showing your CFM50 reduction. This is standard on every job, not available on request. Haven Standard: Have it in writing.
