Insulation Company in Alamo Heights, TX
Insulation in Alamo Heights typically costs between $1.50 and $7.50 per square foot depending on material and application, with most whole-attic jobs landing between $2,800 and $9,400. What makes this city different from everywhere else around San Antonio is the housing stock: century-old masonry and frame homes with uninsulated walls sit three blocks from 1960s ranches with compressed fiberglass batts that stopped working years ago. We send a named technician, a written price before work starts, and a 365-day guarantee on every job. Call (361) 213-9499.
Why Alamo Heights Homes Are Different
Alamo Heights wasn’t built all at once, and that’s exactly what changes the insulation conversation here. The Cottage District near Broadway still holds Craftsman and Spanish Eclectic homes from the 1920s through 1940s. Those homes often have zero insulation in the walls and minimal attic coverage. A retrofit doesn’t mean slapping fiberglass into every cavity; it means understanding how those older structures breathe, where the thermal bypasses hide, and how to keep the original character intact while stopping the heat from pouring through the roofline.
Then you have the 1950s and 1960s ranch-style homes closer to the golf course and along streets like Argo and La Jara. Those attics often have original batts that have compressed to half their rated R-value. Additions complicate things further. We regularly find hidden attic spaces over add-ons that were never tied into the main attic, leaving a channel for hot, humid air to move through the house unchecked.
This city runs hot from May through September, and humidity is a year-round presence. That means vapor control matters as much as R-value here. You can’t just pile insulation into an old Alamo Heights attic without thinking about how moisture moves through it. Done wrong, you get mold in wall cavities and a house that holds heat worse than before. Done right, you get a cooler upstairs, lower bills, and floors that don’t radiate heat back up at you come August.
Our Main Alamo Heights Services
Most Alamo Heights homeowners call us for one of two situations: an older attic that’s bleeding cool air all summer, or a room addition that never got properly insulated in the first place. Here’s what those jobs involve locally.
Attic Insulation in Alamo Heights
Attic work in Alamo Heights starts with air sealing. The older the home, the more gaps exist around ceiling fixtures, plumbing chases, and interior walls that open straight into the attic. We address those before adding material, because insulation over an unsealed attic floor is like a wool coat over a screen door. Homes near the Cottage District and along Patterson Avenue often have vented attics that need baffles installed to keep airflow moving without letting insulation clog the soffits. Materials from brands like CertainTeed and Owens Corning are matched to the attic’s existing condition, not whatever’s left on the truck. See Attic Insulation in Alamo Heights for full pricing and process details.
Spray Foam Insulation in Alamo Heights
Spray foam earns its cost in older Alamo Heights homes where framing is irregular and air leaks are everywhere. Closed-cell foam from brands like Icynene and Demilec goes into wall cavities, band joists, and cathedral ceilings, sealing gaps as it expands. In homes near Broadway with original masonry and frame construction, spray foam is sometimes the only way to get meaningful R-value into tight, shallow cavities without tearing out plaster. It also handles the humidity concern better than fiber batts, since it doesn’t absorb moisture. We always check for knob-and-tube wiring before any foam work begins, which is a real consideration in this city’s older sections. Get specifics at Spray Foam Insulation in Alamo Heights.
Blown In Insulation in Alamo Heights
Blown-in insulation, which is loose fiberglass or cellulose blown through a hose to fill the attic cavity and settle into every gap, works well across most Alamo Heights attics, especially the sprawling ranch layouts near the golf course. It’s faster than batt installation and covers irregular joist spacing without leaving voids. In Alamo Heights homes with older wiring, we coordinate with electricians before any cellulose goes in, because covering original knob-and-tube with loose material creates a fire hazard. This is a specific, known issue in the neighborhoods off Broadway, and we treat it seriously on every job. Fiberglass from GreenFiber or Knauf is often the right call here; see Blown In Insulation in Alamo Heights for line-item pricing.

Knob-and-tube remediation, if found, is a separate electrician’s line item and adds cost. You get a written number before any work begins, and that number does not change on us.
