Our Services
Insulation Services in Seguin, TX
Every home in Seguin has different insulation needs. Some attics need additional insulation, while others may need old material removed or air leaks addressed first. We help homeowners find suitable insulation solutions based on their home's condition, layout, and comfort concerns.
Attic Insulation
If your home struggles to stay comfortable during hot weather, your attic insulation may need attention. We assess existing insulation and recommend suitable upgrades based on its current depth, condition, and your home's needs.
Wall Insulation
Poorly insulated exterior walls can contribute to unwanted heat transfer. Depending on the wall construction, wall insulation may be installed during a renovation or through an appropriate retrofit method.
Garage Insulation
An uninsulated garage can become very hot during summer, particularly when it shares a wall or ceiling with your home. Insulating suitable garage walls, ceilings, or doors can help reduce heat transfer into adjoining spaces.
Crawl Space Insulation
Heat can move through floors above an uninsulated crawl space. Our crawl space insulation solutions depend on moisture conditions, ventilation, and your home's construction.
Fiberglass Insulation
Fiberglass insulation is available as blown-in material, batts, and rolls for different applications. The right option depends on the space, existing insulation, and whether you're upgrading an attic or insulating accessible wall cavities.
Spray Foam Insulation
Spray foam can provide insulation and air sealing in suitable applications. We help homeowners explore open-cell and closed-cell options based on the roof assembly, ventilation strategy, and their home's specific requirements.
Cellulose Insulation
Blown-in cellulose insulation fills around framing and other irregular spaces, making it a practical option for many attics. Proper installation helps provide consistent coverage at the depth needed for your insulation goals.
Attic Air Sealing
Gaps around wiring, plumbing, framing, and attic hatches can allow unwanted air movement between your attic and living spaces. Our attic air sealing service targets these openings to help reduce air leakage and improve insulation performance.
Insulation Removal
Insulation that's wet, pest-damaged, contaminated, or deteriorated may need to be removed before replacement. Our insulation removal service helps prepare your attic for new insulation and allows the underlying space to be assessed.

Insulation in Seguin, TX
When Seguin's summer heat settles in, keeping your home comfortable can become a challenge. You might notice upstairs rooms getting warmer than the rest of the house, your AC running for long stretches, or certain rooms never quite reaching a comfortable temperature.
Sometimes, the problem starts in the attic. Insufficient insulation and gaps that allow unwanted air movement can make it harder to keep indoor temperatures consistent. Whether you live in an older home or a newer property, checking your attic insulation is a practical first step toward understanding what's causing the problem and what can help.
Why It Matters in Seguin
Why Good Insulation Matters for Seguin Homes
- 01Long, hot summers: Seguin is in a hot-humid climate zone. Your attic heats up for months, and that heat pushes down into your rooms.
- 02Humid air: Gaps around lights, vents and the hatch let humid outside air in, which makes your AC work harder.
- 03Older homes: About 4 in 10 Seguin homes were built before 1980, so their insulation has often settled, thinned or been patched over the years.
- 04Comfort all year: The same insulation that blocks summer heat also helps keep rooms warmer on winter nights.

What Our Customers Say
“These guys did a great job on our attic. The crew was friendly, professional, and easy to work with and price was reasonable too. Really happy with the results and would definitely recommend them”
Alex James

“Had my attic insulation done by Frank and his crew, and and tbh I’m really happy with the results and how it turns out. A day after I reached out to them Frank came out to check the attic and gave me an estimate, and just two days later, the crew was back to get the job done. The attic was really in rough shape before, but it looks so much better now. Everyone worked hard and got everything done in a timely manner. Thanks Frank, and thanks to the whole crew for the great work”
Derrick J.

“Frank and his team were great to work with from start to finish. They came out to check our attic, took some pictures, and gave us an estimate pretty quickly. The following week, they returned and installed the blown-in insulation. They did a great job and cleaned up everything afterward, even the small bits left in the street. The price was reasonable, and the whole experience was smooth... Definitely recommend them!”

FAQ
Seguin Insulation FAQs
We bring most attics to R-38 to R-49. The 2021 energy code calls for R-49 in this climate, and R-38 is allowed when it covers the whole attic floor at full depth.
It depends on the space and what's already there. Blown-in fiberglass or cellulose suits most attic top-ups. Spray foam at the roof deck fits attics with ducts or the AC unit, and batts work in open walls. We recommend the option after the inspection.
Yes. Along with attics, we insulate exterior walls, garage walls and ceilings, and floors over a crawl space.
Not always. Dry, sound insulation can usually stay, and we add over it. Wet, moldy, pest-damaged or badly flattened insulation comes out first.
Often, yes. Many Seguin homes are a few decades old, and their insulation has usually settled or been patched over the years. Topping up and sealing the gaps helps keep rooms more even in the summer heat.
It depends on the size of the space and the work needed. Most attic jobs take a day or less, and we'll give you the timing with your quote.
Not right now. Seguin homes get power from City of Seguin Electric or GVEC, and as of October 2026 neither lists an insulation rebate. CPS Energy rebates only apply to CPS customers.
We stop work and leave it alone. The EPA advises treating vermiculite as possibly containing asbestos, so we refer you to an accredited asbestos professional.
