What Westminster Homeowners Say About Topside Attic Insulation Westminster
We’ve insulated and sealed more than 9,000 homes since 2016, and every one of them closed with a documented photo record and a written price agreed to before anyone lifted a tool. Reviews aren’t something we chase. They’re what happens when a Westminster homeowner opens their final packet and sees the before-and-after blower-door numbers, the photos of sealed top plates and can lights, and a scope that matches exactly what was promised. Wes Okafor and our crew don’t perform enthusiasm on the job site. We perform the work, publish the measurements, and let homeowners decide if we earned the call.

Our 1962 ranch near Little Saigon had insulation so old it was crumbling between the joists. Wes walked the attic with me, showed me the compacted R-11 batts, and explained why blowing new material over that mess would be a waste. His crew removed it all, sealed every can light and top plate, then blew in GreenFiber to R-38. The blower-door test dropped from 3,800 CFM50 to 1,900. Our summer AC bills in Westminster have dropped $80 a month, easy.

We got three quotes for spray foam in our crawl space under the Bolsa Chica Road area. Two contractors wanted to start the next day without a written scope. Wes brought a written price, a written warranty, and a photo of what our vapor barrier would actually look like when his crew left. They encapsulated the crawl space with Demilec open-cell foam on the rim joists and a 10-mil vapor barrier on the dirt. No more musty smell coming through the floor registers. The documented photo record showed every seam taped.

After the roof rats got into our attic off Beach Boulevard, I called thinking I’d need insulation removal and replacement. Wes found the entry points, had his crew clean and sanitize the space, then installed rodent-proofing at every penetration. He didn’t sell me more insulation than I needed. The written scope said R-38 blown-in cellulose, and that’s exactly what the post-job photos showed, evenly distributed, no gaps around the baffles. The 365-Day Done Right Promise was in the packet before they started.

My husband wanted to add a radiant barrier himself after watching videos. I called Wes for a second opinion. He brought his own written estimate, walked us through why a radiant barrier alone wouldn’t fix our real problem, which was unsealed recessed lights bleeding conditioned air into the attic. We hired him for attic air sealing plus a radiant barrier on the roof deck. The before-and-after blower-door numbers were 4,100 CFM50 down to 2,200. He published both figures in the final packet. No guessing, no feelings, just the measurement.

We bought a flipped house near the Westminster Mall and the inspection said “insulation present” without any R-value listed. Wes tested it at R-13, well below what Westminster’s climate zone calls for in attics. His crew removed the thin fiberglass, sealed all the penetrations with acoustic sealant, and blew in Johns Manville blown-in to R-38. The crew was uniformed, background-checked, and Wes texted me when they were on the way. Under Haven Standard, you get a named technician and a text. That actually happened.

I had a quote from another contractor for wall insulation using a proprietary foam I’d never heard of. Wes brought a Free Second Opinion, read the competing quote with me line by line, and pointed out where they were charging premium prices for generic open-cell. We went with Topside for Knauf EcoSeal plus dense-pack cellulose in the walls. Written price before work started. Documented photo record when they left. The wall cavities were filled completely, no voids, and the photos proved it. Wes doesn’t sell proprietary lock-in. He uses Owens Corning, Johns Manville, Knauf, Rockwool, and the others, and he tells you why he’s choosing one over the other for your specific job.

Why Customers Trust Us

Every review above points to the same pattern. Westminster homeowners aren’t impressed by promises. They’re impressed by packets. The packet you get from Topside Attic Insulation Westminster contains your written scope, your written warranty, your before-and-after blower-door test, and your documented photo record. That’s Haven Standard. That’s what we’ve delivered on every one of those 9,000 homes since 2016.
We don’t blow insulation over unsealed attic floors. We seal first, then insulate, in that order. We don’t use proprietary products you can’t price-compare. We source from eight major manufacturers so the material choice is based on your home, not our margin. And if something isn’t right, the 365-Day Done Right Promise means we make it right.
