Meet the Milpitas Team Behind Topside Attic Insulation Milpitas
The crew that shows up at your door in Milpitas isn’t a rotating cast of subcontractors. These are the same people who’ve been crawling through Berryessa attics, sealing crawl spaces under homes near the Great Mall, and running blower-door tests in Warm Springs neighborhoods since we opened here. What ties them together is simple: every one of them can explain, in plain English, why your house is losing conditioned air and what the fix will actually cost before any work starts.
Our People
Wes Okafor, Owner
I started this operation in 2016 after watching too many insulation jobs in the South Bay get done backward - blown-in fiberglass dumped over unsealed top plates and recessed can lights that were still leaking like chimneys. Before that, I spent six years in building diagnostics, crawling through attics in San Jose and Fremont with a blower door and a thermal camera. I still carry a respirator in my truck because I climb up to verify the crew’s work on about one job in five, especially in older Milpitas neighborhoods like Milpitas Ranch where the original 1960s insulation is often hiding rodent damage or asbestos-containing vermiculite. The counterintuitive thing I’ve learned: more insulation is rarely the right first move. Seal the envelope first. Measure the result. Then add insulation if the numbers say you need it. Homeowners remember the number on their final blower-door report, not how many bags of cellulose we blew.
Marcus T., Lead Technician
Marcus has been with us since 2019 and runs the crew on our biggest jobs - full attic removals, spray foam installs, and the multi-day crawl space encapsulations we get called for near the foothills where moisture is a constant battle. He’s BPI-certified in Building Analyst and Envelope Professional, which means he can both diagnose the problem and supervise the fix without handing you off to another trade. Marcus is the one who will stop a job mid-morning if his smoke pencil finds a leaky return chase the homeowner didn’t know existed, because he’s seen what happens six months later when that gets buried under new insulation. Off the clock, he rebuilds vintage motorcycles in a garage in San Jose that is, by his own admission, better insulated than most of the houses he works on.
Diana R., Senior Installer
Diana specializes in our blown-in and dense-pack wall jobs, the kind of work that looks straightforward until you’re trying to maintain consistent depth around a Bay Area attic’s worth of irregular joist spacing and obsolete wiring. She came to us in 2021 from a weatherization crew in Oakland and brought a particular skill for working in tight, hot spaces without rushing the details - a necessity in Milpitas, where summer attic temperatures regularly hit 140°F and installers who cut corners leave gaps that show up on thermal imaging six months later. Diana is also our go-to for radiant barrier installations in newer construction near the Tesla plant, where roof geometry is complex and tape-measure precision matters. She keeps a small rock collection from every job site, which she claims is weird but we all tolerate because her blower-door numbers are consistently the best on the team.
Javier L., Service Coordinator
Javier answers the phones and schedules the work, which sounds routine until you try doing it while fielding calls from homeowners who just found a dead raccoon in their attic or discovered their crawl space flooded during the last atmospheric river. He’s been with us since 2020 and has the Haven Standard pricing matrix memorized well enough to give accurate ballpark ranges during the first call - not finalized prices, but real numbers that help people budget before we ever dispatch a truck. Javier is the one who texts you when Marcus is twenty minutes out, and he’s the one who follows up after the job to make sure you received your Documented Photo Record and your written warranty. He grew up in Milpitas, graduated from Milpitas High, and can usually tell you which neighborhood you’re calling from based on the house age and the specific complaint.
Tyler N., Apprentice Installer
Tyler joined us in 2024 after completing a construction technology program at San Jose City College. Right now he’s shadowing Marcus and Diana on every type of job we do, from basic attic top-offs to full envelope retrofits, because the Haven Standard requires that every installer - even apprentices - understand air sealing before they’re allowed to handle insulation. He’s already certified in OSHA 10 and lead-safe renovation, and he’s working toward his BPI Building Analyst credential. Tyler asks more questions than some homeowners do, which we encourage, because the worst installer is the one who pretends to understand something they don’t. He lives with his parents in the Serra neighborhood and commutes on a bicycle that he insists is faster than driving 237 during rush hour, a claim we have not verified.
One Standard, Every Job
Topside Attic Insulation Milpitas is independently owned and operated under The Haven Standard, the same operating framework that governs nine other building-envelope companies across California. What that means on the ground: every crew member who enters your home has passed a background check, wears a uniform with a name tag, and works from a written scope that you approve before any tool comes out of the truck. The 365-Day Done Right Promise applies whether your job takes two hours or two days. Your Documented Photo Record is uploaded automatically, not available on request. And if you bring us a competing written estimate, we’ll read it with you line by line - no charge, no pressure. The Haven Standard isn’t a franchise system; it’s a set of documented commitments that every owner in the network has agreed to uphold. Wes Okafor signed on in 2016 because those commitments matched what he was already trying to build.
