What Los Angeles Homeowners Say About Topside Attic Insulation Los Angeles
We’ve sealed and insulated 9,000 homes across Los Angeles since 2016, and every job closes with a Documented Photo Record. Most of our calls come from neighbors who watched us work on the house next door. That’s how we’ve built this business - not through ads, but through homeowners who tell their friends what the blower-door number was before and after. Reviews aren’t a marketing tactic for us. They’re the only record that matters.

Wes found three inches of blown fiberglass sitting directly on top of unsealed recessed-can penetrations in our Mar Vista attic. The previous installer never sealed anything. His crew air-sealed the top plates and can lights first, then blew in new GreenFiber cellulose. The blower-door test read 3,800 CFM50 before and 1,900 after. We got the photos, the written scope, and the warranty before anyone started. That’s how it should work.

Our 1924 Spanish in Silver Lake had zero wall insulation and a crawl space that smelled like wet concrete every winter. Topside encapsulated the crawl with a vapor barrier, sealed the rim joists, and dense-packed the exterior walls with Rockwool. The written price was $8,400 before work started - not after. No surprises. The crew sent photos from inside the walls we never would have seen otherwise.

I got two other estimates for spray foam in our Encino attic. One contractor wanted to spray directly over the old fiberglass without removing it. Wes explained why that’s a problem - trapped moisture, degraded R-value - and gave us a Free Second Opinion on the competing quote. We ended up going with Topside for full removal, air sealing, and Demilec open-cell foam. The attic is now conditioned space. Our July electric bill dropped 34%.

We bought a flipped house in Highland Park where the inspector flagged inadequate attic insulation. The flipper had blown six inches of fiberglass over everything, including the bathroom exhaust fan dumping moisture straight into the attic. Topside removed it all, fixed the venting, sealed the envelope, and re-insulated with blown-in Owens Corning fiberglass to R-38. They published the before-and-after blower-door numbers: 4,100 down to 2,050. I didn’t have to ask. It was in the packet they handed me when they left.

Our 1960s ranch in Westchester had rats in the attic. The pest company trapped them but wouldn’t touch the contaminated insulation. Wes’s crew did the full job - removed the soiled material, sanitized, rodent-proofed with steel mesh at all penetrations, air-sealed, and re-insulated with Knauf EcoBatt. The photo record showed every square foot before and after. When I called six months later about a minor settling issue, they honored the 365-Day Done Right Promise with no argument. A technician was here the next morning.

I was skeptical of the whole-home energy audit at first. Sounded like a sales pitch. But Wes walked me through the thermal imaging, showed me exactly where our 1940s bungalow in Atwater Village was bleeding conditioned air, and gave me a written scope with line-item pricing for air sealing, wall insulation, and a radiant barrier on the roof deck. We phased it over two years. The radiant barrier alone dropped our second-floor temperature eight degrees in August. Every phase started with a written price. Every phase ended with photos and blower-door numbers.

My contractor in Sherman Oaks wanted to use a proprietary foam I’d never heard of. I called Topside for a second opinion. Wes explained the difference between open-cell and closed-cell Icynene, why closed-cell made sense for our coastal climate with the marine layer moisture, and priced it against Johns Manville and CertainTeed alternatives. No brand lock-in. We chose Icynene based on data, not pressure. The crew was uniformed, background-checked, and texted me when they were twenty minutes out. Under Haven Standard: Arrive on schedule, you get a named technician. They meant it.

Our condo building in Koreatown needed insulation removal after a roof leak saturated the blown-in cellulose. Three companies gave us estimates over the phone without seeing the space. Wes came out, documented the water damage with photos, and gave us a written price for removal, drying time, mold assessment, and re-installation with new GreenFiber. The scope specified exactly how many bags, what R-value, and what the blower-door target was. The board approved it unanimously. We’ve used them for two more units since.
