What Whittier Homeowners Say About Topside Attic Insulation Whittier
Reviews matter because they’re the only marketing we can’t write ourselves. Every testimonial on this page came from a Whittier-area homeowner who got the same three things: a written price before anyone touched a tool, a documented photo record when the crew left, and a 365-Day Done Right Promise in writing. We don’t chase stars; we chase blower-door numbers that hold up and attics that don’t leak conditioned air into the roof deck. Here’s what that looks like from the other side of the hatch.
Recent Reviews
“We bought a 1952 ranch in South Whittier last spring, and the first summer was brutal - upstairs hit 88 degrees while the AC ran nonstop. Wes walked the attic with me and showed me the original batts, compressed to maybe R-11, with daylight visible around the top plates. His crew air-sealed every penetration, blew in GreenFiber to R-38, and the blower-door test dropped from 3,800 CFM50 to 1,900. Our August electric bill was $127 instead of $211. He emailed the before-and-after photos before I even asked.”

“I got two other quotes for spray foam in our crawl space under the Whittier Hills place. One guy wanted to start the next day with no written scope. Wes sat at our kitchen table, read the competing estimate line by line, and pointed out where they were skipping the vapor barrier entirely. We went with Topside. Six months later, no musty smell, no cold floors, and the documented photo record showed every joist bay sealed. That’s the Haven Standard difference - it’s in writing before they start.”

“After a roof leak in Friendly Hills, we needed the wet insulation out and new batts in. I was braced for the upsell - instead, Wes showed me the moisture meter readings on his phone, marked exactly which bays were salvageable, and wrote a price for removal and replacement only where it was actually needed. The crew left a photo record of every bay, dry to 12% moisture content. No padding, no drama. Just the work we needed.”
- Carmen T., Friendly Hills
“Our 1976 split-level in East Whittier had the classic problem: hot upstairs, freezing downstairs. Wes’s team found the thermal bypass at the stairwell wall - a gap maybe six inches wide running from the basement to the attic, completely unsealed. They air-sealed it, dense-packed the wall with Rockwool, and added a radiant barrier to the roof deck. The blower-door number cut in half. I don’t understand CFM50, but I understand that my daughter’s bedroom is finally the same temperature as the thermostat.”
- Allison K., East Whittier
“I called for a second opinion on a $4,200 quote for attic cleaning and rodent proofing. Wes came out, found one active entry point at a vent screen, two old ones sealed by the previous owner with spray foam the rats had chewed through. His written price was $1,850 - screening, flashing, removing the contaminated batts in the affected corner only, and a photo record of the full perimeter. He didn’t try to sell me a full attic cleanout I didn’t need. That’s rare in this town.”
- Stephanie D., South Whittier
“We did the full envelope package: attic air sealing, blown-in insulation to R-49, crawl space encapsulation with a 10-mil vapor barrier, and wall insulation on the north-facing exterior. Wes published the blower-door numbers right on the invoice - 5,200 CFM50 before, 2,400 after. He also noted where we could still improve: the original aluminum windows. No pressure to do more, just the data. The 365-Day Done Right Promise was in the same envelope as the final invoice. Everything documented, everything dated.”
