How GreenFiber Products Fail – and How We Fix Them

GreenFiber makes solid insulation products, but no material is perfect in every Fresno attic. Here’s what we see in the field, with the specific fixes that hold up.

• Sanctuary blow-in cellulose settling against spray foam seams. GreenFiber Sanctuary is a blown-in cellulose product, and in older Fresno homes we often find it paired with spray foam at rim joists or rooflines. Cellulose settles over time, leaving a gap at the foam-to-cellulose transition, and that gap becomes a thermal bypass. We pull back the settled cellulose, refoam the seam with closed-cell, and re-blow the cavity to its original R-value. You’d never spot this from GreenFiber’s product literature because the issue isn’t the material; it’s how the two systems age together in a Fresno attic that swings from 40 to 110 degrees.
• Open-cell foam on the roof deck losing its air seal in Woodard Park-area homes. Open-cell spray foam is a two-part liquid that expands on contact and seals gaps airtight, and it’s a common choice for Fresno roof deck applications. But if the original installer missed a nail penetration or left the foam too thin at the eaves, air moves. We re-foam those weak points rather than telling you the whole roof deck needs to come down. That’s the difference between a $600 repair and a $14,000 re-do.
• Garage ceiling spray foam delaminating from the substrate. This shows up in Fresno garages that weren’t properly prepped before the original spray. Dust on the ceiling joists or a too-cold application day means the foam never fully bonded. GreenFiber’s spray foam lines (open-cell and closed-cell) both need a clean, dry substrate. We scrape back the failed section, prep the surface properly, and re-spray. You get a written guarantee on the repair, not a shrug about what the old installer did wrong.
• Rim joist spray foam with rodent damage. Rim joists on pier-and-beam Fresno homes are a favorite entry point for rodents, and they’ll chew through open-cell foam without hesitation. Closed-cell holds up better, but if the damage is already done, we cut out the compromised section, re-foam with closed-cell, and recommend the homeowner address the entry point separately. We don’t do pest control, but we’ll tell you exactly what we saw up there.
• Spray foam installed over existing batt insulation creating a moisture trap. This one’s a Fresno-specific problem tied to our cool, wet winters. If someone sprays foam directly over old fiberglass batts, condensation collects at the layer junction, and you get mold. The fix is pulling the batts, addressing any moisture damage, and re-foaming the cavity clean. It’s more work, but it’s the only way the job actually holds. Our senior estimator Glenn Hartley checks for this before we quote anything; he’s spent enough time in Central Valley attics to know what bad work looks like from the attic hatch.

Our GreenFiber Spray Foam Insulation Process

Here’s how a GreenFiber spray foam job runs at Woolsey Insulation Fresno, step by step, following The Kingswell Way: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, come back if it fails.

1. 1
   You call (559) 785-2658. A live person answers, 24/7. We ask about your home, your current insulation, and what you’re seeing or feeling. No phone tree.
2. 2
   We schedule an attic inspection. We give you a real arrival window, and we show up in it. Glenn or one of our senior techs climbs into the attic personally and looks at what’s actually up there before quoting anything. Look before you quote – every attic tells you something the paperwork won’t.
3. 3
   You get a written price. We write down the exact scope and the exact dollar figure, including materials and labor, before any work starts. If we find something unexpected mid-job, we stop and call you. The price doesn’t change at the door.
4. 4
   We do the work. Background-checked, uniformed technicians handle the removal, prep, and spray foam application. We use GreenFiber product lines where they’re the right fit, and we’ll tell you honestly when a different material on our truck list (like a Reflectix radiant barrier for a hot Fresno garage) would serve you better.
5. 5
   We test and clean. We verify the foam is curing properly, the R-value is what we quoted, and the job site is left cleaner than we found it. No foam drips on your driveway, no trash in your yard.
6. 6
   You get a written guarantee. Every job includes our 365-Day Done Right Promise: if it’s not done right within 365 days, we come back and fix it at no charge. In writing. No fine print games.
