From the historic homes near downtown and Baylor to the newer builds on the edges of town, Waco houses share one enemy: a long, humid, brutally hot summer. We seal them tight so the AC stops running nonstop.
Waco is where Central Texas heat concentrates, because it's where most of the buildings are. The city sits in a humid subtropical climate where July and August highs run in the 90s and regularly top 100°F, and Gulf moisture keeps some overnight lows near 80°. That's months of cooling load — and in Waco's mix of older and newer housing, most of that load is driven by air leakage the original insulation never addressed.
The U.S. Department of Energy places Waco in Climate Zone 3A, with an attic insulation target around R-38. Plenty of Waco homes fall well short — and even those that hit the R-value on paper leak air through the attic, top plates, and penetrations. Spray foam fixes both the insulation and the leakage in one step.
Waco's housing runs the full range, and each type has its own opportunity. Older homes near downtown, Sanger Heights, and around Baylor often have under-insulated attics and leaky envelopes that respond dramatically to attic sealing. Mid-century neighborhoods have aging fiberglass ready for an upgrade. Newer subdivisions on the city's edges can be sealed tighter than they were built. Whatever your Waco home's vintage, the free estimate identifies where the heat and air are getting in.
The full range of spray foam insulation, available across Waco and McLennan County.
Historic and older homes near downtown and Baylor benefit most from attic sealing and encapsulation — they're often the leakiest. Established mid-century neighborhoods usually have tired fiberglass ripe for removal and a foam upgrade. Rental and student housing around Baylor cuts operating costs fast with a sealed attic. Newer builds can be tightened beyond builder-grade. And Waco has plenty of shops and metal buildings that closed-cell foam transforms.

It depends on the area sprayed, the foam type, and the thickness for your R-value target. We measure your Waco home or building and give a free written estimate rather than a phone guess.
Almost always the attic — it's the biggest source of heat gain and air leakage in a Central Texas home, and the highest-impact place to start. See our attic page.
Yes — the whole city and McLennan County, plus the surrounding communities. Waco is our home base, so response is fast here.
In our hot, humid, air-leaky climate, sealing the envelope is usually the biggest lever on cooling costs. We'll give you a realistic estimate of the impact for your specific home.
The same heat drives bills up across the metro — we serve the communities all around Waco, too.
