What Los Angeles Homeowners Say About Woolsey Insulation Los Angeles
Reviews tell you what a contractor is actually like after the estimate ends and the work begins. We ask every Los Angeles customer to tell us straight: did the crew show up in the committed window, did the written price hold, did the attic stay clean, and does the house feel different. The quotes below come from four homeowners who’ve hired Woolsey Insulation Los Angeles for attic and spray foam work. We didn’t write them, and we don’t coach them. We just do the job the way Glenn Hartley set it up in 2002, and let the work speak.
Recent Reviews
“Our 1947 house in West Adams had maybe three inches of blown-in fiberglass left in the attic, and the upstairs bedrooms were unusable in August. Woolsey’s crew vacuumed everything out, air-sealed the top plates, and blew in Owens Corning fiberglass to R-38. The upstairs dropped nine degrees the first weekend. They left a written price before starting and didn’t add a dime.”
Hector H. – West Adams, Los Angeles
“I had Woolsey spray foam the rim joists and the underside of the roof deck in a converted garage in Highland Park. The two-part foam sealed gaps I didn’t know existed. My electric bill for July came in $62 lower than the same month last year. The crew wore boot covers and laid down runners, and the place was cleaner when they left than when they arrived.”
Luis T. – Highland Park, Los Angeles
“Called at 6:40 on a Saturday morning because I’d found rodent damage in the attic insulation and didn’t want to wait until Monday. A live person answered, scheduled a Monday visit, and the tech showed up in the exact window. He quoted the removal and replacement with Rockwool before any work started, in writing. The 365-day guarantee was included on the paperwork without me asking for it. That’s rare in Los Angeles.”
Daniel B. – Sherman Oaks, Los Angeles
“Glenn’s team reinsulated our attic in Atwater Village with Johns Manville fiberglass after a roof leak soaked the old batts. They didn’t try to sell me spray foam or anything else. The tech walked the attic with me, showed me photos of the wet spots, and gave me a number. Two days later it was done. My wife noticed the house held heat better within a week.”
Paul G. – Atwater Village, Los Angeles
“I manage a fourplex in Koreatown and I’ve dealt with every kind of contractor Los Angeles has to offer. Woolsey is the first company that put the arrival window in writing and hit it. They blow in GreenFiber cellulose in the attics of two buildings for me. Tenants stopped complaining about the upstairs units being hot, and I stopped dreading the phone ringing in the afternoon.”
Hector H. – Koreatown, Los Angeles
“We had spray foam done in a 1950s Eagle Rock home with a low-slope roof and almost no attic access. The crew cut access where needed, foamed the ceiling plane, and patched everything. It was a harder job than most, and they still honored the written quote. Six months later, no issues. That’s the whole review: no issues.”
Luis T. – Eagle Rock, Los Angeles
Why Customers Trust Us
Read those reviews again and you’ll notice a pattern. Nobody mentions pushy sales tactics, surprise charges, or arguing over what the quote said. That’s because Woolsey Insulation Los Angeles runs on The Kingswell Way: say the price before work starts, in writing, every time. Show up in the committed window with background-checked, uniformed technicians. Leave the job site cleaner than you found it. Put the guarantee in writing, covering 365 days after the job. And if something isn’t right within those 365 days, we come back and fix it at no charge. No fine print. No “well, that’s not covered.” Just a written promise from Glenn Hartley and the team.
We carry and install eight insulation brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That matters because your Los Angeles home doesn’t need whatever happens to be on the truck. A 1920s bungalow in Echo Park and a 2015 build in Playa Vista have different needs. Having eight brand options means the material fits the house. It also means we can quote honestly, without padding the price on something the house doesn’t need.
If your attic is under-insulated or your spray foam isn’t performing, call us at (213) 232-7269. A live person answers, 24 hours a day, 7 days a week. No voicemail maze, no automated system, no call-back window. You’ll get a real conversation about what’s going on in your house and whether insulation is the fix. If it is, you’ll get a written price before any work starts. If it isn’t, we’ll tell you that too. That’s how you earn reviews like the ones above.
