Insulation Company in Kirby, TX
Attic insulation in Kirby usually costs between $1,150 and $3,600, and spray foam projects typically run $2,400 to $8,900 depending on square footage and access.

Kirby’s older ranch homes, dense lot lines, and brutal west-facing sun exposure make insulation work here different from anything across the San Antonio line.

Why Kirby Homes Are Different
Kirby is a small, incorporated city almost completely surrounded by San Antonio, and its housing stock reflects a very specific era. Most homes are single-family detached ranches built between the 1950s and early 1980s, many with brick veneer and minimal original insulation. Walls often carry R-11 or less, attics R-19 or less. Attic hatches in these homes commonly sit inside hallway closets or garages, and many lack any weatherstripping or insulation on the hatch itself. That’s a thermal leak most homeowners never notice until a technician points it out with a thermal camera.
Shallow roof pitches and low attic clearance shape how we work in Kirby. Blown-in cellulose or fiberglass is almost always the most practical retrofit method because it settles into the tight, uneven spaces these older attics present. We also contend with tight lot lines and shared walls in Kirby’s denser, close-in subdivisions. That means careful staging outside and quiet, contained work inside, especially when crews are moving materials through a hallway closet access point while a family is home.
Our Main Kirby Services
Kirby homeowners call us most often about two things: bringing an under-insulated attic up to current code and sealing the envelope with spray foam where the home’s construction allows it. Each service has its own Kirby page with pricing detail, product selection, and what to expect on the job.
Attic Insulation in Kirby
Most Kirby attics were built to 1990s standards or worse, and they lose conditioned air through shallow-pitch roof decks and unsealed hatches. Our crews assess what’s already up there, remove or top up as needed, and install blown-in fiberglass or cellulose to the depth that fits the home’s construction and Kirby’s residential energy code amendments. We use products from lines like Owens Corning and GreenFiber, choosing the right material for the attic’s access, depth, and the family’s needs. Full detail is on the Attic Insulation in Kirby page.

Spray Foam Insulation in Kirby
Spray foam works hardest in Kirby’s older homes where batt insulation leaves gaps around plumbing, wiring, and odd framing. Closed-cell and open-cell options from brands like Icynene and Demilec let us match the right product to each home’s moisture exposure, roof pitch, and budget. In Kirby’s hot-humid climate, proper application reduces the radiant heat load that west-facing walls absorb through long summer afternoons. We explain the difference between product types before you commit. See the Spray Foam Insulation in Kirby page for specifics.

Both are common in Kirby’s postwar and mid-century homes. Regardless of where your project lands in these ranges, you will have your exact written number before any crew pulls a hose off the truck.

FAQs About Insulation Company in Kirby
Most Kirby insulation jobs can be scheduled within a few days of your written quote. Emergency calls, like a fallen attic hatch or exposed insulation after a roof leak, get prioritized. Call (903) 437-9164 any time and a live person will tell you the soonest available slot.
Kirby enforces residential energy code amendments that affect insulation requirements, and some retrofits need a permit inspection before and after the work. We handle the paperwork for you and confirm what your specific project requires before we schedule the install, so there are no surprises on inspection day.
Older homes are most of what we do in Kirby. The city’s housing stock is dominated by 1950s to early 1980s ranch homes, and we know how to work around shallow attics, slab foundations, and outdated framing. We match the insulation method to the house, not the other way around.
