Documented Photo Record Included on Every Visit

Before-and-After Blower-Door Numbers on Every Air-Sealing Job
We test your home’s air leakage with a blower door - a pressurization measurement that shows, in one number, how much conditioned air your building envelope is losing. We publish the before-and-after CFM50 reading on every qualifying job in San Marcos. Most homeowners see a 30-50% reduction. You get the paper to prove it.

Before
AfterWhat These Offers Actually Cover
We’ve insulated and sealed over 9,000 homes since 2016, and every one started with a written price. These aren’t seasonal come-ons designed to expire and pressure you. They’re the actual structure of how Wes Okafor and the crew at Topside Attic Insulation San Marcos operate. The December 31, 2026 date is a formality. The practices are permanent.
Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. We don’t lock you into a proprietary product. We seal first, then insulate - always - because blowing fiberglass over an unsealed attic floor is throwing money into the wind. Literally. The conditioned air escapes through top plates, can light penetrations, and every gap a builder left behind.
San Marcos sits in the Texas Hill Country, which means summer attic temperatures regularly hit 140°F and winter cold snaps drop below freezing. Proper envelope work here isn’t about comfort alone. It’s about keeping your HVAC from running itself to death. The blower-door test tells us exactly how much air you’re losing. The photo record shows you what we found. The written price tells you what fixing it costs. Nothing hidden.
FAQ: Offers & Pricing

Every job automatically includes the written price, photo record, and 365-Day Done Right Promise. The Free Second Opinion applies to estimates from other contractors. There’s nothing to stack. Call (737) 337-8049 and we’ll walk you through what applies to your San Marcos home.
We answer live 24/7 and schedule as fast as availability allows. Severe situations - like a compromised crawl space vapor barrier after flooding in the San Marcos area - get priority. Call (737) 337-8049 to check current openings.
We don’t price match. We scope match. Bring us a written estimate and we’ll show you what’s actually included. Often the lower price skips air sealing, uses lower R-value material, or omits cleanup.
