What Santa Monica Homeowners Say About Walt’s Insulation
Reviews from your neighbors carry more weight than any claim we could make about ourselves. When someone on 14th Street or up in Sunset Park tells you we showed up on time, kept the job site clean, and knocked a real chunk off their energy bill, that’s the kind of proof that matters. We’ve been earning that word-of-mouth trust since 2000, one attic and crawl space at a time. Walt Brenner still answers his own phone when it rings, and the technicians who show up at your door are background-checked and uniformed, so you know exactly who’s walking into your house. That’s how you build a reputation that lasts 25 years in a city like Santa Monica, where the marine layer is great for the beach but rough on old insulation.
Recent Reviews
“Our 1920s bungalow near Douglas Park had original insulation that was basically dust. The crew from Walt’s removed everything, air sealed the attic floor, and blew in new Owens Corning fiberglass. Our bedroom finally holds temperature at night instead of swinging ten degrees. The whole job was done in one day and they vacuumed the hallway before leaving.”
Nicole S., Sunset Park, Santa Monica
“I’d been getting quotes for spray foam in the attic and every company gave me a different story. Walt’s offered a free second opinion on the estimate I already had. They walked me through the differences between Icynene and Demilec, and didn’t push the more expensive option just because they could. The final number came in below what the other company quoted.”
Katie D., North of Montana, Santa Monica
“Called at 8pm on a Saturday expecting voicemail. A real human picked up on the second ring and scheduled my crawl space inspection for Monday morning. They found standing moisture, installed a vapor barrier, and sealed the vents. The musty smell in our guest room disappeared within a week. Nobody has ever answered the phone like that.”
Erin Q., Ocean Park, Santa Monica
“We’d been putting off the attic rodent proofing for years. Walt’s crew came out, removed the old contaminated insulation, sanitized everything, and sealed every entry point they could find. They even showed me photos of the gaps up near the roofline. Six months later and not a single scratching sound in the ceiling.”
Alejandro M., Pico Neighborhood, Santa Monica
“Had a radiant barrier installed to help with the afternoon heat that turns our upstairs into an oven. The technicians were in uniform, wore shoe covers the whole time, and explained how the barrier reflects heat before it ever reaches the insulation. I got the 10% senior discount without even asking. It was applied automatically when I called.”
Nicole S., Sunset Park, Santa Monica
“A different insulation company told me I needed a full replacement. I called Walt’s for a second opinion and they found the real problem was air leaking around the recessed lights and plumbing penetrations. They air sealed the whole attic, topped up the blown-in insulation with Knauf fiberglass, and saved me thousands. That’s exactly why I use a local owner-operated company instead of a franchise.”

Why Customers Trust Us
Every review above points to the same things, because those things are the point. We answer the phone with a live person 24/7. Not a voicemail, not an answering service. You call, you get a human, even at 8pm on a Saturday. The technicians who show up are background-checked and uniformed, so you never have to wonder who’s walking through your front door. Every job is backed by the Done Right Promise, our lifetime workmanship guarantee. If it’s not done right, we make it right. No runaround, no fine print. And because Walt Brenner is the owner, not a regional manager three states away, accountability isn’t a policy here. It’s a person with a published address in the county. The one down the road means something. We use materials from Owens Corning, Rockwool, Icynene, Johns Manville, CertainTeed, Demilec, Knauf, and GreenFiber, and our standing offers are simple: $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside the service county, and a permanent 10% discount for seniors and veterans. If you’d like to find out why folks around Santa Monica keep recommending us, call (424) 396-5828 and ask for Walt.
