What Pasadena Homeowners Say About Walt’s Insulation
Reviews tell you more than any ad ever could. They’re the record of what actually happened when our trucks pulled up, when the hoses went into the attic, and when the first utility bill arrived after the job. In Pasadena, where summer attic temperatures regularly climb past 140 degrees, insulation isn’t a luxury add-on. It’s the difference between a house that holds its cool and one that fights the sun all day. We’ve spent 25 years earning this feedback one job at a time, and we’re glad to let the work speak.
Recent Reviews
Our 1926 bungalow in Bungalow Heaven had maybe three inches of old blown-in fiberglass left in the attic. Walt’s crew removed it all, air sealed every top plate and can light, and blew in Owens Corning AttiCat to R-38. The upstairs hallway used to be ten degrees hotter than the living room in August. Now you can’t tell the difference walking up the stairs.

I got four estimates for crawl space encapsulation. Two contractors never even went under the house. Walt’s team spent twenty minutes down there with a moisture meter before quoting. They installed a 12-mil vapor barrier, sealed the foundation vents, and had the humidity below 50 percent within a week. No more musty smell in the front bedroom.
Anika R. · Hastings Ranch, Pasadena
Called on a Sunday morning because I’d found rodent droppings in the attic and didn’t want to wait until Monday to deal with it. A live person answered, which honestly caught me off guard. They scheduled the attic cleaning and rodent proofing for that Tuesday, and the tech showed me photos of every entry point he sealed before he closed anything up.

The previous owner had installed fiberglass batts in the walls, but they were sagging and full of gaps. Walt’s crew removed and replaced everything with Rockwool Comfortbatt. The difference in sound from the street is night and day. We’re on a corner lot on Marengo near Washington, and I used to hear every car that went by. Now it’s just quiet.

I asked for a home energy audit after our gas bill hit $280 in January. The tech found a huge bypass around the chimney chase and a dropped soffit in the kitchen that was leaking air straight from the crawl space. After they sealed those and topped off the attic to R-49 with Johns Manville blown-in, our next January bill dropped by almost 40 percent.

We went with spray foam on the underside of the roof deck because our 1950s ranch has ductwork running through a vented attic. Walt walked me through the differences between Icynene open cell and Demilec closed cell, and honestly told me open cell made more sense for our budget and climate. That kind of honesty is rare. Two summers in, the AC cycles noticeably less.
