Call (626) 606-2964

Walt’s Insulation is an independent CertainTeed service provider, not a manufacturer affiliate. That matters because we can tell you when a product is worth repairing and when it’s cheaper to pull it and start fresh. Call us at (626) 606-2964 anytime. A live person answers, even at midnight.

How CertainTeed Products Fail - and How We Fix Them

• CertainTeed CertaSpray Open-Cell shrinkage around can lights and top plates. In Pasadena’s summer heat waves, open-cell foam expands and contracts more than people expect. We regularly see CertaSpray pulled back a quarter inch from framing in attics that hit 140 degrees. The fix isn’t just re-foaming: we re-seal the gap, check ventilation, and verify the foam’s density hasn’t degraded. Skipping the density check means you’ll be calling again in two years.
• Closed-cell delamination on rim joists in older Pasadena basements and crawl spaces. CertainTeed’s closed-cell foam wants a clean, dry substrate. In 1920s craftsmans around Bungalow Heaven, we find rim joists where decades of damp air caused the foam to lose bond. You’ll see a hairline gap where foam meets concrete or wood. We scrape, dry, and refill with material matched to the existing foam’s density, so you don’t get a patchwork of different expansion rates.
• Garage ceiling spray foam that never cured properly. CertainTeed open-cell needs the right mix ratio and temperature during application. When a previous install was rushed or done on a cold morning, we find soft, tacky foam that never fully set. You can press a finger into it months later. The fix is removal and reapplication. There’s no spray-over solution for uncured foam, and anyone who tells you otherwise is guessing.
• Overspray and weak spots along the roof deck in Altadena and Hastings Ranch additions. CertainTeed roof deck foam works well, but installers who didn’t mask the area leave overspray on rafters and collars. More importantly, we find thin spots at the eave line where the foam tapers down to almost nothing. We bring it back to full depth and clean up the overspray, so rooflines look right and insulate evenly.
• Rodent damage in CertainTeed foam around plumbing penetrations. Pasadena’s rat population loves a foam tunnel. We see chewed-out channels around drain stacks and vent lines in neighborhoods from Linda Vista to Madison Heights. Our fix includes re-foaming with a pest-deterrent additive, then sealing the outer penetration properly so the next rat doesn’t get the same welcome mat.

Our CertainTeed Spray Foam Insulation Process

We run a tight process on every CertainTeed job in Pasadena. Here’s how it works:

1. 1
   You call, we answer. A live person picks up, asks what you’re seeing, and books a visit. No voicemail, no call-back wait.
2. 2
   We inspect the existing foam. We check density, adhesion, moisture levels, and coverage depth. We’ll show you what we find, in plain English.
3. 3
   We make an honest call on repair vs. replacement. If the foam is salvageable, we say so. If it’s cheaper in the long run to remove and reinstall, we’ll tell you that too, even when it means less invoice for us.
4. 4
   We handle the parts decision. For CertainTeed products, we use OEM material where warranty coverage and consistency matter. In some cases, a quality aftermarket foam performs as well for less money. We’ll lay out both options with real numbers.
5. 5
   We do the work and clean up. Uniformed, background-checked techs show up on time. The site is clean when we leave. You’d never know we were there except the insulation actually works.
6. 6
   We stand behind it. Every job is covered by our Done Right Promise. If it’s not done right, we make it right. No runaround, no fine print.

What CertainTeed Spray Foam Insulation Costs in Pasadena

Here’s what we charge for the most common CertainTeed spray foam jobs in Pasadena:

• Open-cell spray foam in an attic or wall cavity: $1.80 to $2.60 per board foot, typical 1,500 square foot attic runs $4,800 to $6,900.
• Closed-cell spray foam for rim joists: $2.80 to $3.60 per board foot, most Pasadena crawl spaces run $1,400 to $2,300.
• Garage ceiling spray foam repair: $450 to $1,100 depending on square footage and whether we’re patching or removing old foam.
• Roof deck spray foam insulation: $3.50 to $5.20 per board foot, with most Pasadena roofs landing between $7,500 and $14,000.

What moves the price? Foam type, square footage, existing foam condition, and access. A tight crawl space in a 1905 craftsman costs more to work in than an open attic, and we’ll tell you that upfront. Estimates are free, and we offer a free second opinion on any written estimate you’ve already received. Call (626) 606-2964 to lock in a number.
