What air sealing does for your houseand why we test it first

If the upstairs runs hot, the floors stay cold or there's a draft by the attic hatch, air is slipping through gaps you can't see. Air sealing closes those gaps between your living space and the attic or crawl space, around light fixtures, wiring, pipes and flues, using caulk, foam or a sprayed sealant so warm air stays put.

Our air sealing services in Jerome, ID start with measuring how leaky the house is, so you have a target to judge the finished work by. After that, anything that needs fixing goes first, because sealing over a leak, a wet spot or bad wiring just hides it.

The price moves with how many gaps there are, how hard they are to reach and how much has to be fixed or checked before we seal. The schedule turns mostly on those repairs, since they come first. I'll write your own number on the estimate after I've seen the house.

You'll know what's leaking, what has to be fixed first and what the finished house should test at. Call (208) 544-9045 to set up a visit.

Where air sealing goes in a house

Every house leaks in its own places, so we seal what we find on the visit, from the attic floor down to the crawl space, with the material that fits each gap.

  • Attic floor and hatch

    Wiring holes, plumbing stacks, can lights and the hatch let air straight into the attic, so we seal each one with caulk or foam before anything goes on top.

  • Big openings and chases

    Insulation alone doesn't stop air, so where a chase, the boxed-in run for pipes or ducts, opens into the attic, we seal rigid blocking over it.

  • Rim joists and crawl spaces

    Air slips in where the house meets the foundation and where pipes come through, so we seal those spots and can pair the work with basement insulation.

I walk you through what's going on in your attic, walls or crawl space before we touch anything, so you understand your house well enough to judge our work.

    Our own installers do the sealing, and I check their work and walk the finished job with you before we call it done.

    I ran insulation jobs years ago and came back in 2021 because I missed the work, and I'd like you to understand your house well enough to judge the next contractor too.

Air sealing questions we hear

How much does air sealing cost in Jerome, ID?

Your price comes from how many gaps your house has, how hard they are to reach and what has to be fixed or checked before we seal. Foam costs more than caulk and blocking, and repairs, added ventilation fans or a venting check on gas or oil appliances add to the scope. I'll put your own number on the estimate after I've looked.

Will air sealing my house affect the indoor air?

It can, because a tighter house can trap carbon monoxide, radon and chemical fumes called VOCs inside. Keeping the air safe may mean adding ventilation fans or fixing whatever gives off the fumes. If you have gas or oil appliances that vent on their own, we have them checked for back-drafting, fumes spilling back into the house, before we seal.

What is the best way to seal and insulate my attic?

Seal first, then insulate, which is also the EPA's advice for attics, so the new insulation lands on a sealed floor. Spray foam seals and insulates in one step but costs more, so sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, usually wins, unless your ductwork runs through the attic and closed-cell foam starts to make sense.

What testing comes with an air sealing job?

We measure how leaky the house is before we start, usually with a blower door test, a big fan set in an outside door, and that number becomes your target. The fan can pull dust and pollen inside and has lifted vinyl flooring that isn't glued down, so plan on a little cleanup and tell us about loose vinyl. If an outside home energy rater runs the test, their fee adds to the cost, and in rural areas bringing one in from out of town can add cost and push the schedule.

Who issues building permits in Jerome, ID?

The City of Jerome's Building Safety Department issues permits for residential, commercial and industrial projects, and it also reviews plans and inspects residential work against the building codes and local ordinances. We check with the office that covers your address before we start, and if your job needs a permit we handle the application and set up the inspections.

How do I find a weatherization program for air sealing near Jerome?

South Central Community Action Partnership runs a weatherization program that includes work to cut air leakage from the home. Contact them to see whether it fits your situation, and if it doesn't, we're glad to walk your house with you.
