What San Jose Homeowners Say About Woolsey Insulation San Jose
Reviews tell you what a brochure can’t. They describe how a crew actually behaves when they’re in your attic for four hours on a July afternoon, or whether the written price you agreed to is the same number on the final invoice. In San Jose, where summer heat pushes attic temperatures past 140 degrees and winter nights dip into the 30s, insulation work has real consequences for your comfort and your utility bill. We earn every review the same way: put the price in writing before work starts, show up inside the committed window, leave the job site cleaner than we found it, and back the work with a 365-day written guarantee. Glenn Hartley, owner at Woolsey Insulation San Jose, reads every review that comes in. They’re the most honest measure of whether we’re doing things right.
Recent Reviews
“Our 1960s ranch in Willow Glen had maybe three inches of blown-in insulation left in the attic. Woolsey Insulation San Jose came out, gave us a written quote for Owens Corning blown-in fiberglass to R-38, and finished the whole job before lunch. The difference in our hallway temperature was noticeable that same evening.”

“I wanted spray foam insulation in the knee walls of our second-story bedroom because that room was always ten degrees hotter than the rest of the house. The technician explained how closed-cell foam expands to seal the gaps and told me honestly that it would help with the temperature difference, but not fix a window that faced west. That honesty sold me. The work was clean and the price matched the quote exactly.”

“We bought a house in Almaden Valley and the home inspector flagged the attic insulation as inadequate. I called on a Sunday afternoon and a real person answered. They scheduled us for Tuesday, gave us a written price before anything started, and the technician walked me through the before-and-after photos. Knauf batt insulation, R-30, installed in about six hours. No surprises.”

“The team from Woolsey Insulation San Jose removed old, dusty fiberglass from our attic in Cambrian Park and installed Rockwool batt insulation. They laid down drop cloths from the front door to the attic hatch and vacuumed the hallway when they were done. My wife is particular about the house and she said she couldn’t tell anyone had been here except the attic was fuller.”

“I got three quotes for spray foam insulation in our San Jose garage conversion. Woolsey wasn’t the cheapest and wasn’t the most expensive, but they were the only one who put the warranty terms in writing without me asking. Three hundred sixty five days, a free return visit if the work fails. That’s what convinced me to go with them. The Demilec foam they used sealed the rim joists tight.”

“Our energy bill in the Rose Garden area was brutal last summer. Woolsey Insulation San Jose blew in GreenFiber cellulose to R-49 and air-sealed the attic floor. The crew wore boot covers and uniforms the whole time, and the tech explained what he was doing at each step. Our August bill dropped by a noticeable amount compared to the year before. Wish we’d done it sooner.”
