Recent work · Exterior retrofit

New siding, so we upgraded the walls first.

On this Austin-area re-side, the old siding came off and the walls were open from the outside. We pulled the original fiberglass batts and filled the cavities with spray foam for added R-value and a tighter air seal, before the siding crew closed it back up. No interior walls were touched.

Spray foam

Open cell or closed cell, sprayed to depth.

Spray foam insulates and air-seals in one step. Open-cell foam is the standard for sealed attics and quiet walls. Closed-cell foam packs the most R-value per inch and stops moisture, which is why it goes on metal buildings, crawl spaces and rim joists.

  • Unvented, conditioned attics
  • Metal shops and barndominiums
  • Walls, rim joists and crawl spaces
  • Ignition or thermal barrier coatings where required

Attics

Blown-in attics brought up to today’s levels.

Most older Austin attics are well short of current recommendations. We seal the big air leaks, install baffles at the eaves and blow fiberglass or cellulose to an even, marked depth across the whole attic.

  • Top-offs over existing insulation
  • Air sealing and eave baffles
  • Old insulation removal when needed
  • Depth markers you can check yourself
Blown-in details
Insulation is only as good as the install.

Gaps, compressed batts and thin spots cut real-world performance. We cut, fit and check depth so you get the R-value you paid for.

How we bid

Walked onsite. Bid in writing. Installed by our crew.

No online price calculators and no ballpark numbers over the phone. Every attic and wall is different, so every bid starts with a visit.

  1. Onsite walk-through

    We get in the attic, walls or crawl space, measure, check existing insulation, ventilation and moisture, and talk through your goals.

  2. Written, itemized bid

    Areas, materials, depths, R-values, air sealing, removal and options are listed line by line with one lump-sum total.

  3. Prep and install

    We protect the house, air-seal where scoped, and install to the specified depth with checks as we go.

  4. Cleanup and walkthrough

    Trimmings and debris are hauled off, and we walk the work with you before drywall or before we leave.

Questions

Common questions

Do you give prices over the phone?

No. Attic size, framing, access, existing insulation, ventilation and the right material vary from house to house, so we walk every job and send a written, itemized bid with one lump-sum total.

Which is better, spray foam or blown-in?

Neither is better everywhere. Spray foam air-seals and can create a conditioned attic; blown-in is the most economical way to add R-value to an attic floor. We will explain the trade-offs for your house and can price both.

Do you work on new construction and existing homes?

Both. We insulate new builds and additions before drywall, and retrofit attics, walls, crawl spaces and metal buildings in existing structures.

Can you remove old insulation?

Yes. Wet, contaminated or pest-damaged insulation can be removed and hauled off before new material goes in. Removal is itemized in the bid.

What areas do you serve?

Austin and surrounding towns including Round Rock, Cedar Park, Leander, Georgetown, Pflugerville, Lakeway, Bee Cave, Dripping Springs, Buda and Kyle.
