What Fresno Homeowners Say About Woolsey Insulation Fresno
Reviews tell you what actually happens after the quote is signed. Not what a website promises, but what the technician did in the attic, how the house felt the next week, and whether the price on paper matched the bill. We earn every review the same way: a written price before work starts, a background-checked technician who shows up in the promised window, and a 365-day written guarantee on every job. If something isn’t right, we come back and fix it. No charge. That’s the standard Glenn Hartley set when he opened Woolsey Insulation Fresno in 2002, and it’s the standard every review below reflects.
Recent Reviews
“Our house in the Tower District was built in the 1940s and the attic had maybe three inches of old, settled insulation. Woolsey came out, measured everything, and gave us a written price before any work started. The crew blew in Owens Corning fiberglass to R-38 and the difference was immediate. Our AC used to run constantly in August. Now it cycles off. I actually checked the thermostat twice because I didn’t believe it.”
Danika E. – Tower District, Fresno
“We had Woolsey spray foam the rim joists in our crawl space. It’s the two-part foam that expands and seals every gap, and they explained the difference between open-cell and closed-cell before we chose. The technician, who was background-checked and in uniform, showed me before-and-after photos on his phone. You could see the old gaps where the framing met the foundation. All sealed now. Our floors are noticeably warmer in winter.”

“Glenn’s team did a full attic cleanup and re-insulation on our rental property near Fresno State. The old stuff was full of rat droppings and dust, and they vacuumed everything out before installing new Johns Manville blown-in cellulose. The written price they quoted covered everything, including the old insulation removal. No surprise charges at the end. Tenants said the house holds temperature way better than before.”
Ernesto D. – Fresno State area, Fresno
“I called on a Sunday afternoon because our attic access had been left open by a previous contractor and all the loose-fill had blown into one corner. A live person answered. Not a voicemail, not a robot. They scheduled us for Monday morning and the technician arrived on time. He re-balanced the Knauf insulation, checked the depth with a ruler to confirm R-38, and even sealed the attic hatch with weatherstripping. The 365-day guarantee was included in writing without me having to ask.”
Karen C. – Sunnyside, Fresno
“Our house in the Fig Garden area had spray foam in the walls from a previous owner who did it wrong. Gaps everywhere, and you could feel the heat bleeding through the outlets in July. Woolsey inspected it, told us honestly which sections were fine and which needed rework, and quoted a written price before touching anything. They use Icynene and Demilec foam, and the technician explained why the original install failed. They fixed what needed fixing and didn’t sell us work we didn’t need. That’s rare.”
Danika E. – Fig Garden, Fresno
“Woolsey installed GreenFiber cellulose in our attic in the Roosevelt neighborhood. The price they gave us up front, in writing, matched the final invoice to the penny. The crew left our hallway cleaner than when they arrived, which matters when you have two kids and a dog. We did not have to vacuum after them. A month later the gas bill showed real savings, and the house doesn’t get that stale hot smell in the late afternoon anymore.”
Megan B. – Roosevelt, Fresno
