What Glendale Homeowners Say About Walt’s Insulation

Reviews tell you what a brochure can’t. When someone in Glendale lets a crew into their attic or crawl space, they learn pretty fast whether the company knows what it’s doing. We’ve been at this since 2000, so we’ve heard it all: the Verdugo Woodlands house where the upstairs never cooled down, the Adams Hill bungalow with the rodent problem above the ceiling, the mid-century place off Brand where the previous insulation had compressed to almost nothing. The feedback below comes from actual customers who called us, watched the work happen, and then lived with the results. That’s the only review that really counts.

Recent Reviews

“Our 1950s home in Glendale still had the original rock wool in the attic, and it was maybe two inches thick in some spots. Walt’s crew pulled all of it out, air sealed every penetration, and blew in Owens Corning fiberglass to R-38. The upstairs bedrooms used to be eight to ten degrees warmer than downstairs in August. After the job, the difference shrank to maybe two degrees. It changed how we use the house.”

Diego T., Adams Hill, Glendale

“We had raccoons get into the attic a few years back, and the insulation was left a mess. Walt’s team did the removal, sanitized the space, and then installed new blown-in insulation plus rodent proofing around the eaves. They explained why the animals got in and what they were doing to keep them out. It’s been over a year and we haven’t heard a scratch up there.”

Sofia M., Verdugo Woodlands, Glendale

“The crawl space under our house was a dirt floor with exposed ducts and a smell that crept up into the living room every summer. Walt’s did a full encapsulation with a vapor barrier, sealed the vents, and the difference was immediate. The house stopped feeling damp. The floors felt warmer in winter. It wasn’t the cheapest quote we got, but the work was clean and the crew left the space looking better than I thought possible.”

Andres V., El Miradero, Glendale

“I called at 9:30 at night because I found what I thought was old water damage in the attic insulation and I needed someone to tell me if it was a problem or not. A real person answered. Not a recording. Walt came out two days later, walked me through what he was seeing, and told me honestly that the insulation was fine but the bathroom exhaust fan was venting into the attic. He quoted the repair and the re-insulation on the spot. No pressure, no scare tactics.”

Veronica M., Rossmoyne, Glendale

“We got three estimates for spray foam in our detached garage that I use as a workshop. Walt’s was the only one that didn’t try to upsell me on the highest R-value foam for a space that doesn’t need it. They used Demilec closed-cell and finished in one day. The garage is usable in July now, which is something I never thought I’d say about a Glendale summer.”

Diego T., Glenwood, Glendale

“The house came with zero wall insulation. It’s a 1940s Spanish-style tract house in Glendale, so the walls were always cold to the touch in January. Walt’s crew drilled and filled with Knauf blown-in insulation, then patched everything so clean you can’t tell they were there. The heating bill dropped noticeably the first winter. My only complaint is I didn’t call them years ago.”

Sofia M., Moorpark, Glendale
