Sioux Falls ranch house at dusk in the snow, shown in thermal camera colors with heat leaking at the roof line

Warm Rooms Start in the Attic

We measure your attic, seal the leaks and blow in more insulation. Most Sioux Falls homes are done in one day.

A thermal look at a ranch on the west side. The bright band at the roof line is heat from the house leaking into the attic.

Is Your Attic Keeping the Heat In?

Poke a ruler into the insulation next to the attic hatch and tell us what you see. We will show your R value next to what a Sioux Falls attic should have.

R value is how well insulation slows heat. Higher is better. Each inch adds about R2.5 to R3.7 depending on the type. The Department of Energy suggests R49 to R60 for attics this far north.

Neighbors Who Warmed Up

We had 4 inches from 1972. They sealed around every light and blew it to 16. The back bedroom is not the cold room anymore.

Gary H. Sioux Falls

Icicles as long as my arm every winter. This year, none. They showed me photos of every gap they sealed.

Renee B. Brandon

In and out in one day, the house was cleaner when they left. The online check was close to what they measured.

Attic Questions

How much insulation should a Sioux Falls attic have?

The Department of Energy suggests R49 to R60 for cold places like eastern South Dakota. With blown cellulose that is about 14 to 17 inches. Many homes built before 1980 have 4 to 6 inches.

Why do you seal before you add insulation?

Warm air leaks up through gaps around lights, pipes, wires and the top of the walls. Insulation slows heat, but it does not stop moving air. Once we pile insulation on, those gaps are buried, so we seal them first.

Will more insulation stop my ice dams?

It helps, but air sealing matters more. Ice dams form when heat from the house warms the roof and melts snow that then freezes at the cold eave. Seal the leaks, add insulation and keep the vents at the eaves open, and most ice dams go away.

I think I have vermiculite. Is that a problem?

It can be. Some old vermiculite has asbestos in it. Do not disturb it. We will not work over it until a sample is tested, and we can set up the test for you.

Do you clean ducts too?

Yes. We clean and seal ducts, and we seal ducts that run through the attic or crawl space so warm air reaches your rooms instead of the attic. It pairs well with an insulation job because we are already up there.

Cold Room at the End of the Hall?

Call and we will come look in the attic, usually the same week. The visit is free.
