It all starts with a free estimate and a straightforward quote.
Takes 30 seconds. No obligation.
Our Services
As an attic insulation contractor in Helotes, we cover every step of insulation installation, from sealing to a full replacement. Pick what fits your attic, or let the inspection decide.

Blown-in insulation made from treated recycled paper that packs firmly around framing and wires.

Sealing the attic floor is easiest before insulation goes on top, so we do it first: fixtures, wire and pipe holes, top plates and the hatch.

If a section is wet, moldy, pest-damaged or flattened, it comes out before new material goes in.

Sound insulation stays where it is. We add on top until the attic floor is even at R-38 to R-49.

An option for attics that hold the ductwork and AC equipment. Foam under the roof deck brings that whole space inside the insulated part of the house.

Loose-fill fiberglass that lays down an even blanket at full depth across open Helotes attic floors.
Planning more than an attic upgrade? Helotes homeowners can also book insulation for finished or open walls or have us handle garage insulation. On homes with a crawl space, crawl space insulation keeps the floors overhead comfortable.

How It Works
We measure depth across the attic and look at condition, air leaks and ventilation.
We explain what your attic needs and what it doesn't.
Sealing, removal and new insulation are quoted as separate items.
Leaks get sealed, the soffit vents stay open and insulation goes in evenly to full depth.
We look over the finished attic together and clean up before we go.
Customer Reviews
“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!”

We recommend R-38 to R-49 across the whole attic floor. We measure your current depth and add only what it takes to get there.
That's your call. A pro job includes sealing the attic floor first, even depth out to the edges and vents kept clear, which are hard to get right with a rented blower.
Yes. After 25 years or more, insulation can settle, get pushed aside during repairs, or be thinner at the edges than it looks from the hatch.
Both. Fiberglass settles very little, and cellulose reaches the same R-value in less depth. We recommend one based on your attic.
Yes. If your attic is already at depth and sealed, we'll say so.
Yes. The visit, the measurements and the quote cost nothing, and you're under no obligation.
Ideally, yes. Once a deep layer goes in, the gaps underneath are hard to reach, so before insulating is the time to seal them.
Attic size, the depth you already have, and whether sealing or removal is needed. We measure during the free visit and price the job from there.
