What West Hollywood Homeowners Say About Walt’s Insulation
We’re not the type to chase you down for a review the second the truck pulls away. But when a homeowner in the Norma Triangle or the West Hollywood West neighborhood tells us their upstairs finally stays cool, or their utility bill dropped $60 in a month, that means something. We ask permission to share those stories because we know reading them helps you decide if we’re the right fit. Every review here reflects the work our uniformed, background-checked crew actually did in a real WeHo home, and they come from people Walt Brenner or one of our techs worked with directly. We keep a folder of these. It never gets old.
Recent Reviews
“Our 1920s Spanish bungalow had maybe two inches of blown-in insulation left in the attic. The upstairs bedroom was unusable in August. Walt’s crew air-sealed every top plate and penetration, then blew Owens Corning fiberglass to R-38. Took one day. The bedroom dropped nine degrees by that evening. I wish we’d done it five years sooner.”
Doug F. - West Hollywood West
“I got four estimates for spray foam in our crawl space and attic. Walt’s wasn’t the cheapest, but they were the only ones who walked the whole house, showed me thermal photos, and explained exactly where the air was leaking. Nobody else did that. They installed Icynene open-cell in the roofline and sealed the rim joists. Our gas bill dropped forty percent last winter.”
Hector F. - Norma Triangle
“We had rats in the attic. I’m a renter, well, a homeowner now, and I was freaking out. Walt’s didn’t just pull the old insulation, they sanitized, sealed every entry point, and blew in new GreenFiber cellulose. The tech showed me before-and-after photos of every gap they closed. Six months later, no rodents, no smell, and the house holds temperature beautifully.”
Kristen W. - Kings Road area
“The team encapsulated our crawl space and it completely changed how the first floor feels. No more cold floors in January, no more musty smell when the AC kicks on. They installed a 12-mil vapor barrier, sealed the vents, and put in a dehumidifier. Every seam is taped perfectly. It looks like a finished room under there now.”
Doug F. - West Hollywood West
“Walt himself followed up after the radiant barrier install to make sure the attic fan was cycling right. I’ve never had a contractor do that. The house is measurably cooler in the afternoon, and our AC doesn’t run nonstop anymore. The crew was in and out in one day, swept the driveway, and wore shoe covers inside the whole time.”
Marisol V. - Eastside WeHo near Plummer Park
“They removed thirty-year-old rock wool insulation that had been soaked through from a roof leak. Full removal, sanitized the attic deck, re-sealed all the recessed light cans, and blew in CertainTeed fiberglass. The smell in the house evaporated within a day. I had another company tell me I needed a full new roof first. Walt’s just fixed the attic. That saved me eight grand.”
Hector F. - Norma Triangle
