Insulation Contractors in Shawnee, KS

Shawnee runs from older post-war streets through to newer subdivisions on the western edge, and the two ends need very different answers.

Two Different Housing Stocks in One City

The older eastern parts of Shawnee were built when attic insulation meant a few inches of whatever was cheapest, and the ceiling below was never sealed. The newer western subdivisions were built to code, which is a minimum rather than a target, and typically run ductwork through an unconditioned attic. The fault is different in each, and so is the fix.

Why Kansas Attics Work So Hard

This is a genuine four-season climate. A Shawnee attic can run far above the outside air in July and sit below freezing in January, and the ceiling between that attic and the house is working against the difference every single day. Over a full year the cost of an unsealed ceiling accumulates in both directions, which is why attic work pays back faster here than in a milder place.

Ductwork in the Attic Changes the Answer

Where the air handler or the duct runs sit above the ceiling, they are operating in the hottest and coldest part of the building. Foam at the roof deck brings that whole volume inside the envelope and takes the equipment out of that environment, which is a different scope from a floor fill and usually the stronger recommendation when the ductwork is up there.

Questions

Common questions

Do you cover all of Shawnee?

Yes, Shawnee and the surrounding Johnson County communities are inside the regular service area.

My house is from the 1960s. Is the attic insulation still doing anything?

Often the material is there but has settled well below its original depth, and the ceiling was never air sealed. We measure rather than guess.

Is spray foam or blown-in better here?

On an open trussed attic both work. Foam at the roof deck also air seals, which matters a great deal if there is ductwork above the ceiling.
