How Topside Attic Insulation La Puente Was Born in La Puente
It was a Tuesday morning in late 2016, and we were standing in the attic of a split-level off Hacienda Boulevard, watching another company’s crew pack up their blowers. The homeowner, a retired mechanic who’d lived in La Puente since the eighties, had paid to have his insulation topped off three months earlier. The new material sat in a fluffy drift over the joists, but the can lights still wheezed conditioned air into the rafters, and the top plates gaped where they met the drywall. He’d paid for R-38 and gotten a snowstorm over a sieve. We remember the exact quality of light in that attic, the dust catching the beam from our headlamp, and the look on his face when we showed him the thermal camera image: 47 degrees at the ceiling plane, right where his daughter slept below.
That afternoon we made two phone calls. The first was to the parent company, Envelope, to ask what it would take to bring their standards to the San Gabriel Valley. The second was to a supplier in City of Industry to price Johns Manville batts and Knauf blown-in systems. We opened the La Puente branch because that mechanic deserved a crew who would seal his attic floor before they counted bags of insulation, who would hand him a blower-door printout instead of a handshake and a prayer. La Puente wasn’t getting that. We promised it would.
Wes Okafor’s Personal Connection to the Insulation Trade
We came to this work sideways. Before insulation, we spent years in building maintenance, crawling through the service corridors of commercial properties in West Covina and El Monte, learning how buildings actually breathe. The first time we opened an attic hatch and felt that wall of 140-degree air drop down in summer, we didn’t think “business opportunity.” We thought: someone lives under this, and no one has explained to them why their second bedroom is uninhabitable in August.
The tradesman who trained us was a blower-door technician out of Whittier, old-school, the kind who’d mutter about “paying to heat the birds” when he found unsealed soffits. We remember the smell of his truck, like mastic and coffee and the particular dust that lives in old fiberglass. We remember the first time we ran a blower door ourselves, in a 1954 ranch near Azusa, watching the manometer twitch as we traced a leak to a plumbing stack with a wisp of theatrical fog. The number was 3,400 CFM50. When we were done three days later, it was 1,800. The homeowner, a woman who’d been sleeping in her living room for two Julys straight, stood at the base of the attic stairs and cried. Not because we’d saved her money. Because she could sleep in her own bed.
That’s the work. Not the bags, not the R-value, not the rebate paperwork. The work is the woman at the bottom of the stairs. If we weren’t doing this, we’d probably still be in maintenance, still crawling around, still trying to figure out why the system doesn’t work the way the drawing says it should. The puzzle is what gets us up. The people under the puzzle are what keep us here.
Meet Wes Okafor - The Person Behind Every Job

Wes Okafor is the Owner and Founder of Topside Attic Insulation La Puente. He holds a C-2 insulation and acoustical contractor classification, carries state-required licensing and insurance, and has spent the last decade working in attics across the San Gabriel Valley, from the hillside homes of Hacienda Heights to the postwar tracts of Baldwin Park. What separates Wes from a corporate franchise technician is simple: he’s the one who answers when the local coordinator patches through a question about your job, and he’s the one who reviews every blower-door report before it goes to the customer.
Outside of work, Wes rebuilds vintage motorcycles, a hobby that taught him patience with seized bolts and the value of doing it right the first time. He lives by a rule he applies to engines and attics alike: if you’re going to open it up, leave it better than you found it. When you hire Topside Attic Insulation La Puente, Wes is personally accountable for that standard on your job.
Our Promise to La Puente Homeowners
Our values aren’t decoration. They’re the operating system we run on, borrowed from the Haven Standard that governs every Envelope branch.
Have it in writing. Clause 1 of the Haven Standard means your price is flat, your scope is itemized, and your warranty is printed before anyone touches your attic. We learned this after watching too many homeowners in La Puente sign vague work orders and get billed for “additional material” they never approved. Our estimates specify the square footage, the target R-value, the air-sealing detail, and the blower-door target. No handwriting, no verbal promises.
Evidence on every job. We photograph what we find - the unsealed top plates, the exhaust fans venting into the attic, the disconnected ducts - and we photograph what we leave. You get the before-and-after blower-door number in writing. Not because it’s impressive, but because it’s proof you bought what you paid for.
No surprises. If we open your attic and find something we didn’t quote, we stop, we show you, and we write a new line item before we proceed. No “while we’re in here” pressure. No scope creep. That’s Haven Clause 5, and it’s why we sleep fine at night.
Our Credentials

Every pro working under our name is required to hold the license and insurance their state requires. Here’s what that means for your home:
- State-licensed - C-2 insulation and acoustical classification, the specific credential California requires for attic work. Not a general contractor padding their scope. The license number is on your written estimate, and you can verify it with the CSLB before we start.
- Insured & bonded - Coverage that protects your property while our crews are in your home, and bonds that back our contractual commitments. We carry this because attics involve ladders, electrical wiring, and the risk of accidental damage to your ceiling. You shouldn’t absorb that risk.
- Years of local experience - Since 2016, we’ve worked in the specific climate conditions of the San Gabriel Valley: the Santa Ana wind events that pressurize attics, the summer heat that degrades fiberglass at the roofline, the winter temperature swings that find every unsealed gap. That local knowledge changes how we approach your job.
- Strong local reputation - We are known in La Puente, West Covina, and the surrounding cities for the documentation we provide and the standards we refuse to compromise. Our customers refer us because they have the paperwork to show what was done.
These credentials matter because you’re inviting someone into your home to work in a space you can’t easily inspect yourself. The license proves we’ve met California’s technical bar. The insurance protects you if something goes wrong. The documentation habit proves we’ll show you what we did, not ask you to trust us. That’s the Haven Standard, and it’s why we publish the numbers other companies keep in their heads.
Rooted in La Puente
We’re not tourists here. Our crews know the difference between the 1950s slab construction near Amar Road and the hillside framing above Vallecito Drive, where wind-washing strips R-value from exposed gable ends. We’ve worked through the September heat when the Santa Ana fires turn the sky orange and attic temperatures hit 160 degrees. We’ve replaced insulation in homes near the 60 freeway where decades of traffic particulate have settled in old blown-in material. La Puente is where we opened, where Wes lives, and where we answer the phone. The standards come from Envelope. The knowledge of your specific house comes from here.
