What Our Customers Are Saying
"Walt came out himself, stuck his head in the attic, and told me I had about four inches where I needed fourteen. No sales pitch, just the number and what it would cost to fix it. Crew was here two days later."
"The house had rats in the attic insulation and a smell we could not place. Walt's crew pulled all of it, sealed the gaps where they were getting in, sanitized, and put in new blown-in. He sent photos of the sealed openings so I could see it done."
"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."

Insulation Service Across the West Covina Area
We Are the West Covina Team for Walt's.
Walt Brenner sticks his own head in the attic before he quotes anything, and tells you the depth you have and the depth you need in inches, not adjectives. He has talked more customers out of spray foam than into it. The written price is the price, the crew's van has his name on it, and he still answers the phone himself - including when somebody texts him a moisture reading from a crawl space he did six years ago.
Same training, same parts, same pricing practice, and the same 90-Day Done Right Promise - delivered by people who live here.
