Attic Insulation Installation Options in Boerne
As an attic insulation contractor working in Boerne, we choose the method by the space. An open attic floor, a tight slope above a vaulted ceiling and the attic beside a bonus room can each call for something different.
Blown-In Fiberglass Insulation
Fills wide, open attic floors evenly, even with plenty of framing and wiring to work around. It's a dependable choice for large attic areas.
Spray Foam at the Roof Deck
Sprayed under the roof deck so the whole attic becomes part of the insulated house. Useful where a complex roofline leaves little floor to work with, or where ducts and equipment sit up top.
Blown-In Cellulose Insulation
A good match for low corners and shallow attic sections, where it packs in tight around the framing.
Attic Air Sealing
We seal wiring holes, duct chases, light fixtures and attic doors so outside air stays out in July and in January.
Attic Insulation Top-Up
When the existing layer is sound but short, we add to it until every section reaches R-38 to R-49.
Wall Insulation
Insulation for finished or open walls. In homes with bonus rooms and vaulted ceilings, the walls that border attic spaces can let in as much heat as the ceiling does.
Beyond the attic, Boerne homes can get garage insulation, and when worn-out or pest-damaged material has to go, we handle insulation removal before anything new goes in. Is the house raised over a crawl space? Insulating it with our crawl space insulation service makes the rooms above easier to keep comfortable.

Vaulted Ceilings, Bonus Rooms and More Than One Attic in Boerne
A simple ranch-style attic is easy to insulate. If your Boerne home has a more complicated roofline, the hard-to-reach parts are the ones most likely to be thin.
- Open attic floors: The easy part. We measure the depth and fill it evenly to the target level.
- Space above vaulted or sloped ceilings: Room can be tight here, so we check what fits. Blown-in cellulose may suit these spots better than a deep fiberglass layer.
- Bonus rooms tucked under the roof: These rooms can run hotter than the rest of the house. We check the attic spaces beside and above them for thin coverage and air leaks.
- More than one attic space: Additions and split rooflines can mean separate attics with separate hatches. We inspect and measure each one, not only the one over the garage.
You get one plan that covers the whole house, not just the easy part.
Why It Matters
Why Attic Insulation in Boerne Matters in Summer and Winter
- 01A different climate zone: Boerne is in Kendall County, which the 2021 IECC places in Climate Zone 3A. Bexar County, home to San Antonio, is Zone 2A. Zone 3 is the cooler of the two, so winter heating plays a bigger part in Boerne.
- 02The city's code: Boerne lists the 2021 IECC among its current codes. Under that code, Zone 3 attics need R-49. R-38 is accepted instead when it spans the full attic floor without compression and carries out past the top plates at the eaves.
- 03Mostly built since 2000: About 68% of Boerne homes were built in 2000 or later. For most of them, the job is measuring and filling in, not replacing.
- 04An older core as well: About 15% were built before 1980, including homes in and around the Main Street historic district. Those attics get a closer look for old material and air leaks.

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”
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
Your Boerne Attic Insulation Questions, Answered
R-49 is the 2021 IECC level for Climate Zone 3, the code Boerne uses. An R-38 layer also qualifies if it reaches every corner of the attic floor at full height.
Yes. Kendall County is Climate Zone 3A, while Bexar County is 2A. Both zones call for the same attic level under the 2021 IECC, but winter heating matters a bit more in Boerne.
If there's an accessible space above it, yes. Where room is tight, cellulose or spray foam at the roof deck can work better than a deep fiberglass layer, and we check during the inspection.
It can. We check the attic spaces around the room for thin coverage and air leaks, then fix what we find.
Yes. We inspect and measure every attic space we can safely reach and include each one in the quote.
Yes. Homes near the historic district get a careful check of the existing insulation, air leaks and attic access before we recommend anything.
Blown-in insulation on the attic floor suits most homes. Roof deck spray foam costs more and makes sense mainly when ducts and HVAC equipment sit in the attic or the roofline leaves little floor space.
After we measure. The number of attic sections, their size, the current insulation and any sealing or removal all shape the quote, and the visit is free.
