Our Services
Attic Insulation Services for Schertz Homes
Our attic insulation contractors handle insulation installation in Schertz homes of every age, whether yours needs a few more inches or a complete restart. Choose the service that fits, or we'll recommend one after the inspection.
Blown-In Fiberglass Insulation
Blown-in insulation that fills around joists and wiring evenly. It's a good fit for open attic floors that need more depth.
Blown-In Cellulose Insulation
Dense, treated recycled paper that packs into gaps and around obstacles, which helps in tight attics.
Attic Insulation Top-Up
When your current insulation is dry but thin or settled, we add over it until every part of the floor sits at R-38 to R-49.
Insulation Removal
Insulation that's soaked, moldy, chewed up by pests or packed flat gets cleared out, so the new layer starts on a clean floor.
Attic Air Sealing
We seal the top plates, wire and pipe holes, light fixtures and the hatch so hot attic air stops leaking into your rooms.
Spray Foam at the Roof Deck
Foam applied under the roof deck to bring the attic inside the insulated part of the home. A bigger upgrade that makes the most sense when your HVAC equipment is in the attic.
Insulating more than the attic? Schertz homeowners can also book insulation for existing walls and garage insulation. For homes over a crawl space, insulating under the floor helps the rooms above stay comfortable.

Older or Newer Home? Your Schertz Attic Needs a Different Fix
Schertz has homes from almost every decade, and the age of your house usually tells us where to look first.
- Homes from the 1950s and 60s, like the ones in Aviation Heights: We check what kind of insulation is up there, how much is left, and where air leaks through the ceiling. These attics often need sealing and sometimes a clean-out before new insulation goes in.
- Homes from the 1980s and 90s: After 25 or more years, loose insulation can settle, get packed down or be moved around by later repairs. Many of these attics are ready for a measured top-up.
- Homes built in 2000 or later: Newer doesn't always mean full. We measure the depth over several rooms, and if your attic is already where it should be, we tell you.
Why It Matters
Why Attic Insulation Matters in Schertz
- 01Long, humid summers: Schertz is in Climate Zone 2A, the hot-humid zone. Your attic heats up through the afternoon, and a thin insulation layer lets that heat reach the rooms below.
- 02A local code baseline: The City of Schertz lists the 2015 IECC as the state-mandated energy code, which calls for R-38 in Zone 2 attics. We aim for R-38 to R-49 across the whole floor.
- 03Many homes have reached the top-up stage: About 27% of Schertz homes were built between 1980 and 1999, and about 17% before 1980. That's a lot of attics with insulation that has been in place for decades.
- 04Air leaks matter as much as depth: In humid air, gaps around fixtures, wiring and the hatch let hot, damp attic air into your home. Sealing them first makes the new insulation work harder.

Customer Reviews
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”

“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”

“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
Schertz Attic Insulation FAQs
R-38 at a minimum. The City of Schertz lists the 2015 IECC, which calls for R-38 in Zone 2 attics, and we often recommend going up to R-49.
Only if it's wet, moldy, pest-damaged or crushed. If it's dry and sound, we seal the air leaks and add new insulation over it.
Often, yes. Loose insulation can settle or get packed down over time, so we measure the depth across the whole attic and top up only where it's short.
Yes, as long as the existing layer is dry and in good shape. That's usually the most affordable way to reach R-38 or more.
Both work well when installed to full depth. Fiberglass settles very little, while cellulose packs into gaps and reaches the same R-value with less depth, which helps in tighter attics.
Usually, yes. Insulation slows heat, but it doesn't stop air. Sealing gaps around fixtures, wiring and the hatch first keeps hot attic air out of your rooms.
Yes. We inspect your attic and give you a price at no cost and with no obligation.
It depends on your attic's size, how much insulation is already there, and whether removal or air sealing is needed. We measure during the free estimate and give you a price before any work starts.
