Expert Attic & Home Insulation in San Antonio

The EPA estimates homeowners can save an average of 15–20% on heating and cooling costs by adding insulation and air sealing. In Texas, where summers routinely exceed 100°F, attic insulation upgrades often reduce cooling costs by 30–40%. Many of our San Antonio and Austin customers report saving $75–$150/month during peak summer months.

For attics in South and Central Texas, blown-in fiberglass or cellulose insulation is most popular — it's fast, fills every gap, and achieves R-38 to R-60 coverage. Spray foam is ideal for sealed attics, rim joists, and anywhere you need an airtight moisture barrier. Batt insulation works well for new construction walls. We assess your home and recommend the right solution for your climate zone.

Most residential attic blow-in projects are completed in 3 to 6 hours, including prep, installation, and cleanup. Spray foam jobs vary based on square footage but are typically done in a single day. We send before-and-after photos so you can verify the work.

Yes. We offer professional insulation removal for old, damaged, pest-contaminated, or mold-affected material. We use commercial vacuum systems to extract the old insulation cleanly before installing fresh, high-performance material. This is especially important for homes with rodent damage or insulation over 15–20 years old.

Crawl space encapsulation seals your crawl space from outside air, moisture, and pests using heavy-duty vapor barriers and spray foam insulation. In Texas, humidity can cause mold, wood rot, and higher energy bills if your crawl space is unsealed. If you notice musty smells, high humidity, or inconsistent floor temperatures, encapsulation is highly recommended.
