Meet the Union City Team Behind Topside Attic Insulation Union City
We’re the crew that shows up in your driveway with a blower door, a camera, and a written scope already in your inbox. Every person on this page has worked in attics and crawl spaces across Union City, from the older ranch homes off Decoto Road to the newer builds near the BART station. What ties us together is simple: we seal first, insulate second, and we document every step so you know what you paid for.
Our People
Wes Okafor, Owner & Lead Insulation Technician
I’ve been crawling through attics since 2016, and I still carry a flashlight in my truck that I’ve replaced six times. I started Topside Attic Insulation Union City because I got tired of seeing homeowners in Alameda County pay for insulation that got blown over leaky top plates and unsealed can lights. The PG&E bill barely budged, and the contractor was already gone. That’s why we run a blower-door test before we touch anything, and another one after we’re done. I hold a BPI Building Analyst certification, which means I can read your home’s pressure envelope and tell you exactly where your conditioned air is escaping. When I’m not chasing air leaks, I’m usually arguing with my smoker about brisket timing at the Union City farmers market on Sundays.
Marcus T., Senior Installer
Marcus has been with us four years, and he’s the reason our spray foam jobs in Union City don’t have the cold spots or off-gassing complaints you hear about from cut-rate outfits. He’s certified in Icynene and Demilec application, and he treats every hose pull like he’s working on his own mother’s house in the Alvarado district. He grew up in Hayward, so he knows the microclimate here: the morning fog that rolls off the bay, the afternoon heat that bakes south-facing attics, and how that temperature swing stresses batt insulation over time. Marcus collects vintage Raiders gear and will absolutely notice if you still have original T-111 siding that needs sealing before we insulate.
Diana R., Service Coordinator
Diana answers the phone when you call (510) (650) 381-1512, and she’s the one who makes sure your written price lands in your inbox before Wes or Marcus ever steps on your property. She’s been handling building-envelope scheduling for six years, and she can tell you whether your job needs a two-man crew or four, how long we’ll need access to your attic hatch, and whether your HOA in the Station District will want to see our certificate of insurance. Diana lives in Fremont but drives the Dumbarton every morning because she likes the quiet before the calls start. She keeps a spreadsheet of every Union City permit requirement by neighborhood, which has saved more than one job from a three-week delay.
Javier L., Apprentice Installer
Javier joined us in 2024 after two years in residential HVAC. He’s learning the full sequence: attic inspection, photo documentation, air-sealing with fire-rated caulk and foam, then insulation placement. He’s already certified in OSHA 10 and lead-safe work practices, which matters more than people think in Union City’s pre-1978 housing stock. Javier asks more questions than anyone on the crew, which is exactly what you want in someone who’s going to be working over your head. He commutes from San Leandro and brings the coffee. He’s also the reason we started carrying Spanish-language scope summaries, after he translated for a homeowner on Alvarado Boulevard who wanted to read every word before signing.
One Standard, Every Job
Topside Attic Insulation Union City operates under The Haven Standard, the same system that governs nine other independently owned building-envelope companies across California. What that means for you: every crew member is background-checked and uniformed, every job starts with a flat written price and scope, and every visit ends with a Documented Photo Record uploaded to your file. The 365-Day Done Right Promise applies whether Wes did your air sealing or Javier did his first solo top-plate detail. We don’t have callback windows measured in business days. A live person answers (510) (650) 381-1512 at any hour, and if something’s not right, we make it right. No urgency theater, no franchise boilerplate, just the same crew in the same trucks, showing up on schedule with a named technician and a text when we’re on the way.
