What Huntington Beach Homeowners Say About Walt’s Insulation
Reviews tell you more than any advertisement can. When a Huntington Beach homeowner takes the time to write about a crew that showed up on time, kept the job site clean, and fixed a problem that previous contractors missed, that’s real information. We’ve been working in attics and crawl spaces around Huntington Beach since 2000, and the reviews below reflect what our customers say matters most: straight answers, real material brands, and work that stays done. No scripts, no cherry-picking. These are the comments we’re proud to earn on every single job.
Recent Reviews
“Our upstairs bedrooms in Huntington Beach were hitting 85 degrees every summer afternoon. Walt’s team pulled out the old fiberglass that had settled to almost nothing, air sealed every penetration, and blew in Owens Corning AttiCat to R-38. Three days later we had a heat wave and the upstairs stayed at 74. I actually checked the thermostat twice because I didn’t believe it.”

“I’d gotten three bids for crawl space encapsulation and the prices were all over the place. Walt Brenner came out himself, spent forty minutes under the house, and showed me photos of standing water I didn’t know was there. The written estimate explained exactly what a vapor barrier would and wouldn’t do. No scare tactics. We went with them and the crawl space is bone dry now, even after the winter rains.”

“Had rodents in the attic over our garage in Huntington Harbour. Walt’s crew removed every bit of the contaminated insulation, sanitized the space, sealed the entry points, and installed new blown-in. The technician showed me the gap where rats were getting in near the roofline. Nobody else who looked at it even mentioned that. It’s been eight months and not a single scratch sound.”
Greg V. – Huntington Harbour
“We bought a 1967 ranch home in Huntington Beach with walls that had zero insulation. The difference after they injected dense-pack CertainTeed into the exterior walls is honestly hard to describe. The house holds temperature now. The heater doesn’t run constantly. And the crew patched every hole so cleanly that after paint you’d never know they were in there. True professionals.”
Brian L. – Huntington Beach, Edison Community
“Called on a Saturday morning because my attic access had water staining and I was worried about mold. A real person answered the phone, which in 2026 feels like a miracle. They scheduled me that same week, did a full attic inspection, and found the issue was a bathroom vent fan duct that had come disconnected. They didn’t try to sell me insulation I didn’t need. They told me exactly what a fair fix looked like. That’s why I’ll only call Walt’s from now on.”
Carlos T. – Huntington Beach, Northeast
“Our energy bills in Huntington Beach were creeping up every year, so we had Walt’s do a home energy audit. They found the real culprits: recessed lights leaking air into the attic and a section of wall insulation that had slumped down in a bedroom wall. The fixes weren’t dramatic or expensive, but our summer SCE bill dropped noticeably. What I appreciated most was that the auditor explained everything in plain English and didn’t push a single unnecessary upgrade.”
