What Yorba Linda Homeowners Say About Topside Attic Insulation Yorba Linda
We’ve insulated and sealed more than 9,000 homes since 2016, and every one of them started with a written price and ended with a documented photo record. Reviews matter to us because they’re the only marketing we can’t write ourselves. The feedback we get from Yorba Linda homeowners usually mentions three things: we show up when we say we will, we explain the blower-door numbers in plain English, and we leave the attic cleaner than we found it. Wes Okafor, Owner, reads every review personally. If something’s off, the 365-Day Done Right Promise means we fix it.
Recent Reviews
“Our 1978 home in Travis Ranch had original R-11 batts that were compressed and stained. Wes walked the attic with me and showed me the top plates leaking air around every wall partition. His crew air-sealed first, then blew in GreenFiber to R-49. The blower-door test started at 3,800 CFM50 and finished at 1,900. Our summer AC runtime dropped by about a third. Written price was exactly what we paid.”
Ramon F., Travis Ranch, Yorba Linda
“We bought a house near Yorba Linda High School with a crawl space that smelled like mildew and had standing water after every rain. Topside encapsulated it with a 10-mil vapor barrier, sealed the rim joists with closed-cell spray foam, and installed a dehumidifier. They sent me photos of every step. No more smell, no more damp. The written scope listed every material by brand name.”

“I got two other estimates for spray foam in my detached workshop off Imperial Highway. One contractor wanted to quote me after he started. Wes gave me a flat written price for Demilec open-cell on the roof deck and walls, with the warranty terms spelled out before anyone touched a hose. The crew was uniformed, background-checked, and texted me when they were twenty minutes out. Haven Standard Clause 1 is real.”
Keisha F., East Yorba Linda, near Imperial Highway
“Rats had torn up our attic insulation and left debris everywhere. Topside didn’t just vacuum it out and leave. They rodent-proofed with steel mesh at all penetration points, sanitized the decking, air-sealed the can lights and duct chases, then blew in Owens Corning ProPink to R-60. The photo record showed before, during, and after. Wes pointed out a disconnected flex duct the rodents had chewed through that we’d never have found.”
Claudia R., Bryant Ranch, Yorba Linda
“Our PG&E bill in July was $487 and the upstairs never got below 78 degrees. Wes ran a blower-door test that read 4,200 CFM50, which he explained means my house was leaking conditioned air like a sieve. They sealed the attic floor, the chimney bypass, and the bathroom fan housings, then added blown-in Rockwool. Final reading was 2,100 CFM50. August bill was $312. Same thermostat setting.”
Ramon F., Travis Ranch, Yorba Linda
“I brought Topside a written estimate from another contractor for radiant barrier installation in my garage attic. Their Free Second Opinion meant Wes sat down with me and read the competitor’s scope line by line. The other company was going to staple foil to the rafters without air-sealing first, which Wes showed me would trap moisture against the roof deck. We hired Topside to do it right: seal first, then install the radiant barrier with proper standoffs for ventilation. Written price, documented photos, blower-door numbers before and after.”

Why Customers Trust Us
The pattern in these reviews isn’t accidental. Every Yorba Linda job follows the same sequence because the building envelope doesn’t forgive shortcuts. We seal first, then insulate. Air sealing of top plates, can lights, and penetrations happens before any insulation goes in. We don’t blow material over an unsealed attic floor because we’ve seen what that costs homeowners in lost efficiency and moisture problems.
The before-and-after blower-door numbers aren’t a party trick. A blower-door test is a pressurization reading that shows, in one figure, how much conditioned air your building envelope is losing. When Ramon’s house dropped from 3,800 to 1,900 CFM50, that wasn’t a feeling. That was a measurable fact he could compare to his next energy bill.
The 365-Day Done Right Promise applies to every completed job. If it’s not done right, we make it right. The written scope and written warranty arrive before anyone lifts a tool, per Haven Standard Clause 1. No exceptions. The Documented Photo Record is included on every visit, not available on request. You get it automatically, same as the written price.
Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary lock-in means we specify what’s right for your home, not what moves our inventory. Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7. No voicemail loops, no callback windows measured in business days.
We’ve sealed and insulated more than 9,000 homes since 2016. Every one started with a written price and closed with documentation. If you’re in Yorba Linda and your attic reads R-11 while your energy bill reads painful, those two facts are related. Call (909) 323-1675 and we’ll send Wes or one of our technicians to walk your attic and give you a flat written price before any work starts.
