Get answers to common questions about insulation services in San Antonio, Texas.
For our long, intense summers, spray foam and radiant barrier insulation are highly effective as they provide superior air sealing and reflect radiant heat from the sun. Typical costs in San Antonio range from $1,500 to $3,500 for an attic, depending on material, square footage, and existing conditions. While blown-in fiberglass is a lower upfront cost, spray foam often offers better long-term energy savings by significantly reducing AC strain.
The ideal times are late fall (October-November) and early spring (February-March). These periods avoid the peak summer heat, which makes attic work dangerous for crews and can affect foam curing, and also avoid the holiday rush. Scheduling during these milder seasons ensures better availability from reputable contractors and allows you to prepare your home's efficiency before the punishing summer heat arrives.
Yes, CPS Energy frequently offers rebates for attic insulation upgrades for their customers, which can significantly offset project costs. Additionally, federal tax credits for qualified energy efficiency improvements are available. It's crucial to choose a certified installer who understands the specific program requirements, as proper documentation and meeting prescribed R-value targets are necessary to qualify.
Look for licensed, insured contractors with specific experience in Texas heat and humidity. Verify they perform a thorough energy audit or assessment first. Check for membership in local associations like the Greater San Antonio Builders Association (GSABA) and read reviews focused on their communication and post-installation service. Always get 2-3 detailed, written estimates that specify material type, R-value, and scope of work.
Absolutely. In San Antonio, the attic is the primary source of heat gain. Inadequate insulation allows radiant heat to bake into your living spaces, forcing your AC to run constantly. Other local factors like humidity can also compress old insulation and reduce its effectiveness. A professional assessment can identify if your attic insulation meets the recommended R-38 to R-60 for our climate zone.
