Residential FAQ — Katy, TX
What's the most cost-effective first spray foam upgrade for my Katy home?
For most Katy homes, attic spray foam delivers the fastest payback. If your HVAC and ducts are in the attic, roofline foam is typically the best starting point. If the attic is storage-only, attic floor foam with full air sealing at the top plates is the priority.
Does spray foam work with older Katy homes from the 1990s?
Yes — retrofit spray foam is one of our most common applications in Katy. Older homes in Cinco Ranch and Kelliwood typically have settled fiberglass batts, uninsulated rim joists, and poor air sealing. Spray foam can be installed in existing homes through targeted upgrades or full envelope replacement.
Can you insulate my home while I'm living in it?
Yes. We phase work to minimize disruption. Attic foam is typically done in one day with no need to leave. Crawl space work is similarly non-disruptive. Walls in occupied homes require drill-and-fill techniques. We'll walk through the process during the estimate.
Do you offer financing for residential spray foam?
Yes — 0% interest financing is available for qualified homeowners. Ask about financing options during your estimate appointment.
