What Lancaster Homeowners Say About Topside Attic Insulation Lancaster
We’ve sealed and insulated over 9,000 homes since 2016, and every job closes with a Documented Photo Record and a written price that was agreed to before anyone lifted a tool. The reviews that matter to us aren’t the ones that sound polished; they’re the ones where a homeowner in Lancaster can point to a specific number, a specific neighborhood problem, and a specific outcome. Here’s what people actually said.
Recent Reviews
“Our house in Quartz Hill was built in 1987 and the attic basically had nothing left up there. Wes walked the whole space, showed us photos of the compressed fiberglass and the gaps around the can lights, then gave us a written price for air sealing first, then blowing in new GreenFiber. Blower-door test started at 3,800 CFM50 and ended at 1,900. Our summer PG&E bill dropped from $340 to $210 the first August after.”

“We bought a place in West Lancaster with a crawl space that smelled like wet concrete every time the Santa Ana winds shifted. Topside put down a vapor barrier, sealed the rim joists, and insulated the crawl walls with closed-cell spray foam. They sent us before-and-after photos of every corner, and the written scope matched exactly what they did. No more smell, and the floors aren’t cold in January anymore.”
Diego V., West Lancaster
“I had two other companies quote me on radiant barrier for our single-story in East Lancaster. One wanted to staple foil to the rafters and call it done. Wes explained that without proper ventilation baffles we’d just trap heat. His crew installed the barrier with proper air gaps, and we got the blower-door numbers to prove the attic wasn’t leaking conditioned air upward. Written price before work started, just like he said.”
Michelle N., East Lancaster
“Rats had been in our attic near the Sierra Highway corridor for two seasons. Topside didn’t just clean it out; they sealed every penetration, replaced the contaminated insulation, and showed us photos of each entry point they closed. The 365-Day Done Right Promise meant something because they came back at month four to check a spot I’d noticed near the gable vent. No charge, no argument.”
Veronica D., Sierra Highway area, Lancaster
“Our 1970s ranch in Rancho Vista had the original blown-in that had settled to about four inches in some spots. Wes measured the depth everywhere, marked it on a diagram, and gave us a written price to bring it to R-38 with new Owens Corning blown-in on top after sealing all the top plates and electrical penetrations. The crew arrived when they said they would, sent a text thirty minutes out, and left the attic cleaner than they found it.”
Marcy P., Rancho Vista, Lancaster
“I brought Topside a written estimate from another contractor for spray foam in our detached garage conversion near Avenue K. Their Free Second Opinion wasn’t a sales pitch; Wes sat with me and read the competitor’s scope line by line. Pointed out they were quoting open-cell where closed-cell was needed for the thin walls, and that the price didn’t include air sealing the garage-to-house connection. His revised scope was more work but the final number was lower because he wasn’t guessing.”
Diego V., Avenue K area, Lancaster
“After the February 2023 windstorm, our insulation got soaked where the roof vent had failed. Topside removed the damaged batts, dried the deck, and didn’t try to sell me more than I needed. They documented everything with photos, gave me a written price for replacement only, and noted in the scope that I’d need a roofer for the vent itself. No upsell, just accurate work.”
Michelle N., Central Lancaster
“We’d been in our Lancaster home fifteen years and never thought about the attic until the upstairs bedrooms hit 85 degrees by 3 PM every July. Wes ran a home energy audit, found the return duct was pulling 120-degree attic air through a gap in the chase, and fixed that before adding any insulation. Blower-door dropped from 4,100 to 2,200. The bedrooms stay under 78 now with the same AC unit.”
Veronica D., North Lancaster
“My neighbor used Topside for crawl space encapsulation and mentioned the Documented Photo Record. When I hired them for wall insulation in our 1960s addition, I got the same thing: photos of every stud bay before and after, the written scope with material specs, and a final walkthrough where Wes showed me the blower-door improvement. It’s one thing to say your house is tighter; it’s another to hold the paper that proves it.”
Marcy P., Lancaster
“I was skeptical of the ‘sealed first, then insulated’ claim because another company said they could just blow over what was there. Wes opened the attic hatch at our West Avenue I house and pointed to the visible gaps around the chimney chase and the exhaust fan housing. Said blowing over that would be paying to hide a problem, not fix it. Two days of air sealing, then new insulation. PG&E bill is down 34 percent year over year.”

Why Customers Trust Us
Every review above mentions the same elements because they’re built into how we operate, not added as marketing afterthoughts. Haven Standard Clause 1 requires a written price, written scope, and written warranty before any work starts. The 365-Day Done Right Promise means if we missed a penetration or if a material settles unevenly, we return and correct it. The before-and-after blower-door numbers aren’t a bonus; they’re standard documentation on any job where air sealing is performed, so a Lancaster homeowner can verify the result in a single figure rather than waiting for twelve months of utility bills.
Our materials come from eight major manufacturers, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary lock-in means we specify what actually fits the house and the budget, not what a franchise agreement requires us to push.
Calls are answered by a live person, not a voicemail loop, and our technicians are background-checked and uniformed. You’ll get a text when your technician is on the way, with a name attached.
If you’re comparing estimates or just want to understand what your attic or crawl space actually needs, call (661) 526-2890. We’ll read any written quote with you, no obligation, and give you a second opinion based on what’s in the scope, not what’s in the sales pitch.
