Air sealing from attic to crawl space
Attic air sealing
Closing the openings between your living space and the attic, like can lights, wire holes and the hatch. It suits a drafty upstairs or a climbing power bill.
Crawl space and floor sealing
Sealing where the house framing meets the foundation and where pipes and wires pass through the floor, which suits cold floors and rooms that feel drafty down low.
What does air sealing fix in a drafty house?
Air sealing services in Kennewick, WA close the gaps that let air leak in and out of your house, mostly between your rooms and the attic or crawl space, so rooms draft less and your heating and cooling don't run as hard. The same leaks can carry moisture that warps wood and leads to mold, so sealing them protects the framing too.
Most calls start with one room that never feels right, cold floors, or a power bill that keeps going up. What the job costs and how long it takes turn mostly on how much insulation we have to pull back to reach the leaks and whether anything needs repair first, and the schedule also waits on any permit check with the city. We write out what we plan to do and why after we've seen the space, and if the attic needs more insulation afterward, attic insulation goes on after the gaps are closed.
Air sealing and the work around it
The leaks that cost you most usually hide under the attic insulation, not just around doors, so we look for them there first and let what we find decide the rest of the job.
Fixing what can't be covered
Damp insulation, rotted rafters, a bath fan venting into the attic or knob and tube wiring comes first, before we seal over it.
Pulling back the insulation
We move the old insulation off the tops of walls, can lights and wire holes, because those open into the rooms below.
Sealing gaps by size
Caulk goes on small cracks and foam on bigger gaps, and where moisture is a worry we use closed-cell foam, dense enough to keep it out.
Sealing the foundation edge
Down below, we seal the edge of the floor framing and the pipe holes, and that work often pairs with basement insulation or crawl space work.

Questions about sealing air leaks
How do I know if my house needs air sealing?
Drafty rooms, rooms that run warmer or colder than the rest of the house, and heating or cooling bills that keep climbing are the usual signs. Ice dams, dry indoor air in winter and dust in the rooms right under the attic point the same way. When you get an assessment, ask whether it checks ventilation too, since a house needs enough of it to keep damaging water vapor and harmful gases from building up.
How much does air sealing cost in Kennewick?
Air sealing in Kennewick doesn't have a flat price, because the cost comes from what's in your attic and crawl space, and I can only tell that once I've looked. Lots of can lights and wire holes, deep insulation to move, a tight crawl space or foam over a large area all push it up. Foam costs more because it seals and insulates in one pass, but sealing the gaps and topping up the loose fill, insulation blown in through a hose, usually wins unless your ductwork runs through the attic.
Can I seal air leaks in my house myself?
Yes, for the leaks you can see, like gaps around door frames and where pipes and wires come through a wall. The small leaks hidden under the attic insulation are a different job, because a professional assessor finds those with a blower door test, a big fan that pulls air out so leaks show up, and an infrared camera that shows where heat slips through. If you'd rather hand off the attic part, call (509) 396-5461.
Is air sealing safe if my house has a gas or oil furnace or water heater?
It can be, as long as the appliances are checked, because sealing sometimes makes a naturally venting gas or oil furnace or water heater pull its exhaust back into the house. The usual advice is to test that they draft properly before and after sealing, so when a house has them, we plan for draft testing as part of the job. A tighter house can also hold in carbon monoxide, radon and VOCs, the fumes some paints and cleaners give off, so it may need a ventilation fan or a fix at the source, and that belongs in the plan too.
What is the best way to handle vermiculite insulation in my attic?
Leave it undisturbed until an approved lab has tested it, because vermiculite, a light, pea-size, flaky gray mineral, may contain asbestos. Your local health department can name a lab that does the testing. If I find it on the visit, I'll tell you plainly, and nothing gets sealed or moved up there until the results are back.
What should an insulation contractor in Washington have before working on my house?
Washington requires every construction contractor to be registered with the state Department of Labor & Industries and to be bonded and insured. Ask any contractor you're weighing about all three before you sign, and have their written plan in hand so you know what they intend to do.
Work that often goes with air sealing
Closed-cell foam insulation
Closed-cell foam fits spots that need air stopped and moisture kept out in one layer, like a damp crawl space wall.

If the basement or the floors above it stay cold, insulating the basement walls once the gaps are sealed brings that level closer to the rest.

Once the attic is sealed, adding insulation to an even depth, full at the edges as well as the middle, is what keeps the rooms below comfortable.

What to know about air sealing services in Kennewick
The City of Kennewick says not every project needs a building permit and points owners who aren't sure to its Building Safety Division or Community Planning Division, so instead of assuming, we check with the city before work starts and take care of the permit with them when one's needed. Washington also requires contractors to give you a written disclosure notice on any home job of $1,000 or more, and if a contractor's work leaves you with a financial loss, eligible homeowners can now apply for payment through the state's Homeowner Recovery Program.
We're based in Kennewick and work in the cities around it on both sides of the state line. On jobs here and in Pasco and Richland, we find older houses with can lights and open wire holes under settled insulation, and newer ones where the room over the garage never keeps up, so we check both before planning.
