This page is for Fresno homeowners who already have CertainTeed products in their attic or walls and want spray foam work done right. We’ll walk through how CertainTeed materials age here in the Central Valley heat, what breaks, what it costs to fix, and how we handle the job from first call to final cleanup.

How CertainTeed Products Fail, and How We Fix Them

CertainTeed makes solid insulation products, but Fresno summers push every material to its limit. Attics here routinely hit 140 degrees in July, and that heat accelerates breakdown in ways the manufacturer’s own literature doesn’t always address. Here’s what we see on CertainTeed jobs around Fresno:

• CertainTeed OPTIMA blown-in fiberglass settling around existing spray foam. We see this in older Tower District and Fig Garden homes where somebody added spray foam years ago but left OPTIMA in the floor joists. The blown-in material compacts over time, dropping from R-30 to something closer to R-19 in spots. Our fix is removing the settled material, air-sealing, and applying open-cell foam directly to the attic floor for a continuous thermal barrier.
• Gaps at the roofline where CertainTeed MemBrain was used as the original air barrier. MemBrain is a smart vapor retarder, not a seal. In a Fresno summer with 100-degree days stacking, the membrane can’t stop convective air movement the way spray foam does. We regularly find insulated attics in Clovis and Woodward Park where MemBrain is intact but the house still loses cool air through unsealed top plates. We spray the roofline or floor to actually seal the envelope.
• Closed-cell foam pulling away from CertainTeed DryRight sheathing. DryRight is a coated OSB product meant to shed moisture, and closed-cell foam needs a clean, dry substrate to bond properly. In some older installations around northwest Fresno, we’ve found foam delaminating because the sheathing’s coating was never properly prepped. The symptom is cold spots and condensation in the attic. We remove compromised foam, prep the surface, and respray.
• Rim joist bays in homes with CertainTeed basements showing air infiltration. Fresno doesn’t have many basements, but for the homes that do, a rim joist left with just fiberglass batts is an open door for hot air. We spray closed-cell foam into rim joist bays in under an hour per bay, and the temperature difference in the floor above is immediate.
• Older CertainTeed CertaSpray open-cell absorbing moisture from roof leaks. Open-cell foam is vapor permeable, which is fine normally. But if a Fresno roof leaks even slightly, open-cell holds that moisture against the decking and you get mold before you ever see a ceiling stain. We find this in older homes near the Tower District where original roofs are aging. We pull the wet foam, get the roof fixed, and respray once everything’s dry.

Our CertainTeed Spray Foam Insulation Process

Here’s how a job runs when you call us about CertainTeed spray foam in Fresno:

1. 1
   You call, a person answers. No phone tree, no voicemail. You describe the problem, we ask the right questions.
2. 2
   We schedule a look. Glenn Hartley or one of our lead techs comes out, climbs into the attic, and checks what’s actually there. Look before you quote, every attic tells you something the paperwork won’t.
3. 3
   You get a written price. The number is based on what we saw, and it doesn’t change at the door. It covers material, labor, cleanup, and the guarantee.
4. 4
   We do the work. Background-checked, uniformed technicians show up in the window we committed to. We prep the space, spray the foam to the right depth and R-value, and clean as we go.
5. 5
   We test and walk you through it. Before we leave, we verify the foam cured properly and the depth is where it should be. You see the attic before and after.
6. 6
   You get the guarantee in writing. Every job includes our 365-Day Done Right Promise. If something isn’t right within a year, we come back and fix it at no charge.

What CertainTeed Spray Foam Insulation Costs in Fresno

Here are honest ranges for common CertainTeed spray foam scenarios in Fresno:

• Open-cell spray foam, attic floor, 1,200 sq ft: $1,800 to $2,600
• Closed-cell spray foam, roofline, 1,500 sq ft: $3,200 to $4,500
• Rim joist spray foam, full perimeter: $800 to $1,400
• Garage ceiling spray foam, 400 sq ft: $700 to $1,100
• Targeted foam repair (pulling and respraying damaged sections): $400 to $900

What moves the price is access, foam depth, and how much prep the surface needs. A tight Fresno attic with a low pitch costs more in labor than a walkable one out in Clovis. You’ll get a written price before any work starts, and that number is the number you pay. Call (559) 785-2658 and we’ll come out and give you the real figure.
