CertainTeed Spray Foam Insulation in Converse: What to Know First
We provide independent CertainTeed spray foam insulation in Converse, with most jobs completed in one day and a written price delivered before any work starts. As an independent CertainTeed service provider, we carry no manufacturer authorization - just two decades of hands-on experience with their product lines and the documentation to prove what changed. Typical turnaround from signed scope to finished job is 24-72 hours, depending on foam type and cure time. Call (830) 420-0953 for a free estimate with flat pricing.
This page is for Converse homeowners who’ve found CertainTeed spray foam in their attic, walls, or rim joists and need to know whether it can be repaired, topped off, or removed and replaced - and what that actually costs.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed CertaSpray Open-Cell in hot Converse attics: The 0.5 lb/ft³ density absorbs atmospheric moisture when the attic ventilation is compromised by soffit blockages or ridge vent failures. We’ve pulled CertaSpray that’s gained 15-20% water weight in Live Oak Park-area homes where the ridge cap was installed backward. Our fix: remove the saturated foam, seal the ventilation path, then reapply - never encapsulate wet substrate.
- CertainTeed CertaSpray Closed-Cell with off-ratio application: When the A-side (isocyanate) and B-side (polyol) mix drifts from the 1:1 specification, the foam shrinks, cracks, or remains tacky indefinitely. In Converse’s humidity, off-ratio closed-cell pulls away from studs within 18 months. We test the existing foam with a core sample and visual inspection; if it’s failed, we cut it out and reapply to manufacturer density - 2.0 lb/ft³ for CertaSpray CC.
- CertainTeed IntelliFoam (legacy open-cell) in garage ceiling applications: Discontinued around 2018, IntelliFoam was often applied too thin over unsealed drywall, creating a thermal bridge at every fastener. The foam itself isn’t the problem; the installation is. We find this in Schertz-adjacent subdivisions built 2015-2019. Our fix: strip to substrate, air-seal the drywall-to-truss junction with acoustical sealant, then reapply modern open-cell to full 5.5″ depth for R-38.
- CertainTeed spray foam at rim joists with bulk water intrusion: In Converse’s clay-heavy soils, rim joists see capillary wicking during spring saturation. Foam applied over damp wood traps moisture and promotes rot. We pull the foam, treat the wood with borate, install a vapor barrier if grade conditions warrant, then refoam - always with a moisture meter reading below 18% before trigger time.
- CertainTeed CertaSpray with inadequate substrate preparation: Dusty OSB or oil-contaminated surfaces prevent adhesion. The foam “skins” but doesn’t bond, creating a hidden air gap. We see this in new construction where framers worked through the weekend and the substrate was never cleaned. Our prep: HEPA vacuum, primer if needed, then application - the Haven Standard requires it in writing.
Our CertainTeed Spray Foam Insulation Process

- 1
Call and scope: A live person answers. We schedule a site visit, not a phone guess. Wes Okafor or a named technician arrives on time - you get a text when we’re 15 minutes out.
- 2
Diagnostics and documentation: We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing in CFM50. We photograph the existing CertainTeed foam, note the series, density, and condition. You get a written scope with flat pricing before any work starts.
- 3
Parts decision: For repairs or top-offs, we match CertainTeed’s specified density and chemistry. For full removal and replacement, we may recommend CertainTeed, Icynene, or Demilec based on your envelope goals - no proprietary lock-in.
- 4
Air sealing first, then foam: Top plates, can lights, penetrations, and chimney chases get sealed with foam, caulk, or fire-rated sealant as appropriate. We never blow or spray over an unsealed surface.
- 5
Application and cure management: Open-cell needs 24 hours minimum; closed-cell needs 24-48 depending on thickness. We control attic temperature and ventilation during cure - critical in Converse’s summer heat, where substrate temperatures above 110°F can cause flash cure and poor adhesion.
- 6
Verification and closeout: Post-job blower-door test, Documented Photo Record uploaded, printed report with before-and-after CFM50 readings handed to you. The 365-Day Done Right Promise begins.
Before
AfterWhat CertainTeed Spray Foam Insulation Costs in Converse
Most CertainTeed spray foam jobs in Converse fall in these ranges, based on what we’ve priced since 2016:
- Rim joist only (open-cell): $1,800-$2,800
- Rim joist only (closed-cell): $2,400-$3,600
- Garage ceiling, open-cell to R-38: $2,200-$3,500
- Attic roof deck, open-cell (complete): $4,500-$7,500
- Attic roof deck, closed-cell (complete): $6,500-$10,000
- CertainTeed removal and replacement (attic): Add $1.50-$2.50/sq ft for safe extraction and disposal
What moves the price: accessibility (scaffolding vs. walkable attic), existing foam condition (removal adds labor), and whether the substrate needs repair before reapplication. We also service Reflectix radiant barrier systems if your project includes hybrid insulation strategies.
Every estimate is free, every price is written, and every job starts only after you sign the scope. Call (830) 420-0953 for yours.
Why Converse Homeowners Call Topside Attic Insulation Converse for CertainTeed Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Converse teach you something specific: the combination of clay soil, hard freeze-thaw winters, and summer attic temperatures north of 140°F means insulation that works on paper often fails in practice. We document the difference with blower-door numbers, not promises.
Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7. The 365-Day Done Right Promise - if it’s not done right, we make it right - is backed by a written scope and written warranty delivered before anyone lifts a tool. That’s Haven Standard Clause 1. We also provide a Free Second Opinion on any written estimate; bring us a competing quote and we’ll read it with you.
Seal the leaks first. Then insulate. The numbers will tell you if it worked.
FAQs
CertainTeed’s spray foam warranty covers material defects, not installation errors - and it requires documentation of proper application density and conditions. We provide that documentation: photos, core samples if needed, and written verification of substrate moisture and temperature at application. If the foam itself is defective, our records support your claim with CertainTeed. Call (830) 420-0953 and we’ll review what’s in your attic against the warranty terms.
Most Converse homeowners get a site visit within 24-48 hours of calling, and emergency situations - bulk water intrusion behind foam, active roof leaks - get same-day assessment. The actual repair timeline depends on cure requirements: open-cell needs 24 hours, closed-cell 24-48. We don’t rush cure times; we manage them. Call (830) 420-0953 to schedule.
Repair is cheaper when the foam is sound but thin or discontinuous - we spot-apply to achieve full R-value. Removal and replacement is necessary when the foam is water-saturated, off-ratio, or poorly adhered; patching over failed substrate wastes money twice. We tell you which category you’re in after inspection, not before. Free estimates mean you get that answer at no cost. Call (830) 420-0953.
We don’t stock CertainTeed foam in our Converse warehouse - no independent contractor should; the chemicals have shelf life and temperature requirements. We order to spec after you approve the scope, with typical delivery in 2-3 business days. For urgent jobs, we can source equivalent-density foam from Icynene or Demilec if your project goals allow. The written scope specifies exactly what you’ll receive.
You get a printed blower-door report: CFM50 before, CFM50 after, and the percentage reduction. On most Converse homes, proper air sealing plus spray foam cuts leakage 30-50%. The Documented Photo Record shows the work; the numbers show the result. If the blower-door doesn’t improve, we find out why before we leave - that’s the Haven Standard.
