Before / After
From a bare, leaking attic to a sealed envelope
Most Valley attics we open are under-insulated and full of air leaks. This is what changes after a professional spray foam install.
Before- Thin, settled insulation
- Air leaking at every gap
- Attic temps over 140°F
After- Continuous air seal
- Even, code-correct R-value
- Cooler rooms, quieter house
Photos represent typical attic conditions before and after a spray foam install in the Rio Grande Valley.
Energy Savings
Your AC isn't the problem. Your insulation is.
In the Rio Grande Valley, cooling can eat half of an electric bill. Sealing and insulating the attic and walls keeps conditioned air inside, so your system cycles less and lasts longer.

FAQ
Answers before you commit
Still have a question? Call us and you'll get a straight answer — not a sales pitch.
How much does insulation cost in McAllen?+
It depends on the material, square footage and the condition of what's already up there. Spray foam costs more upfront than batt or blown-in but delivers the strongest air seal and the biggest savings. Every estimate is free and itemized in writing before you decide.
Is spray foam better than blown-in or batt insulation?+
Spray foam air-seals and insulates at the same time, which matters a lot in Valley heat and humidity. That said, blown-in and batt are excellent, cost-effective choices for many attics and walls. We recommend based on your building — not on what we'd rather sell.
How long does an insulation job take?+
Most residential attics are finished in a single day. Larger retrofits, whole-home projects and commercial buildings are scheduled around your timeline and confirmed in writing before we start.
Do I need to remove my old insulation first?+
Sometimes. If the existing material is contaminated, water damaged or badly settled, removal is the right call. Otherwise we can often top up to reach the correct R-value. We'll tell you honestly during the inspection.
How much will I actually save?+
Homeowners commonly see up to 40% lower heating and cooling costs after proper air sealing and insulation, plus more even temperatures and noticeably less AC runtime.
Do you work on new construction and commercial buildings?+
Yes. We work with builders, general contractors and commercial property owners across the Rio Grande Valley, and we keep to the construction schedule.
