Our San Antonio Attic and Crawl Space Services
Professional Attic and crawl space services from the team locals trust
San Antonio’s mix of historic neighborhoods and fast-growing suburbs means attic conditions vary block to block. Homes near the city center often carry decades of aging insulation, while newer construction on the outskirts sometimes gets by with the bare minimum builders install to meet code. Both situations run into the same problem once San Antonio’s long, hot summers set in. Insulation that’s too thin, too old, or simply insufficient lets heat push into living spaces and drives up cooling costs for months at a time.
Attic Construction extends our team’s full range of attic, ductwork, and crawl space services to homeowners throughout San Antonio.
Lower your energy bills and stabilize your home’s temperature. We install high-performance blown-in fiberglass or cellulose insulation to create a robust thermal barrier that keeps you cool in summer and warm in winter.
Maximize your home’s energy efficiency and comfort. We provide professional insulation solutions that keep your home cool in the summer and warm in the winter.
Safely extract old, damaged, or contaminated insulation. Using industrial vacuums, we remove materials soiled by rodents or moisture, leaving a clean slate for a fresh, efficient installation.
Stop pests permanently. We identify and seal all entry points—from roof vents to foundation cracks—to prevent rats and mice from invading your home, protecting your wiring and insulation from damage.
Eliminate biohazards and foul odors caused by rodent infestations. We use hospital-grade disinfectants to neutralize bacteria, viruses, and pheromones, ensuring your attic is safe and sanitary for your family.
Restore your home’s hygiene by removing decades of accumulated dust, construction debris, and allergens. We clear out the mess to improve your indoor air quality and prepare your attic for energy-efficient upgrades.
Block up to 97% of the sun’s radiant heat from entering your attic. This reflective foil technology significantly reduces attic temperatures, lowers cooling costs, and extends the lifespan of your HVAC system.
Breathe easier with clean, efficient airways. We offer comprehensive duct cleaning, sealing, and replacement services to remove allergens, stop energy leaks, and improve the overall airflow in your home.
Protect your home from the ground up. We transform damp, dirty crawl spaces into clean, dry, and energy-efficient environments.
We provide professional air sealing services focused on the attic. Our goal is simple: stop uncontrolled airflow, improve insulation performance, and create a more stable indoor environment.
Our Process for San Antonio Homeowners
Every project starts with a free inspection so we can see exactly what your attic, ductwork, or crawl space needs, whether your home is a historic property or a newer build on the city’s edges. From there, we explain our findings and recommend only what your home actually needs. Our team handles the work directly, and most projects wrap up in a single visit. We finish with a walkthrough so you can see the results firsthand.
Why San Antonio Homeowners Choose Attic Construction
A city with this much variation in home age and construction needs a team that evaluates every attic on its own terms.
- Experience across housing types: We know what to look for in both historic San Antonio homes and newer suburban construction.
- Fiberglass-only insulation: We never substitute cellulose or spray foam, so you know exactly what’s protecting your attic.
- Backed by our established Austin team: San Antonio homeowners get the same licensed, bonded, and insured crews already serving the greater Austin area.
- One-year workmanship warranty: If anything about the work needs a second look, we come back and take care of it.

House is more comfortable and utility bills are noticeably lower. Solid work all around.
After comparing several companies, went with Attic Construction for our energy efficiency upgrade. They sealed ducts, added insulation, and installed a moisture barrier. Transparent pricing, showed up when they said they would, and the results speak for themselves.

Very pleased with the insulation work Attic Construction did in Irving.
They were prompt, respectful of my property, and worked efficiently. I’ve noticed a significant reduction in outside noise, which was an unexpected but welcome bonus!

Thank you Attic Construction for a perfect job with a very fair price !
We saw this company doing A project to our neighbor and we asked them to come to do inspection at our attic because we had rodent problem too. We decided to do the same project as our neighbor did and we have to say that we had the best experience I ever had with any contractor I ever worked with…

Frequently Asked Questions About Attic Services in San Antonio
Do you have a local office in San Antonio?
We serve San Antonio as part of our greater Austin service area, with the same in-house crews handling both regions.
Can older San Antonio homes still benefit from fiberglass insulation?
Yes. Historic homes often have outdated or insufficient insulation, and fiberglass upgrades can make a significant difference in comfort and energy costs regardless of a home’s age.
Do newer San Antonio homes ever need attic work?
Yes. Some new construction uses minimum builder-grade insulation and ductwork, which may not hold up as well as expected through San Antonio’s long summers.
What areas around San Antonio do you serve?
We work throughout San Antonio and the surrounding areas as part of our broader Central Texas service area.
How do I get started?
A free, no-obligation inspection is the first step. We will assess your attic, ductwork, and crawl space and recommend only what your home actually needs.
