Cold floors, musty smells, and high heating bills often come from air leaks in the attic and crawl space - not the heating system. We find and seal them, then prove it with before-and-after testing.
Air sealing in Bremerton means finding the gaps, cracks, and openings where outside air gets into your home - then closing them permanently - and most jobs on a single-family home take one day with no disruption to your living areas.
Most air leaks are not where you would expect. The biggest culprits hide in the attic - around light fixtures, plumbing pipes, and the tops of interior walls - and in the crawl space below. If your home was built before 1990, it was never designed to meet today's air tightness standards, which means there is a very good chance warm air is escaping every hour of the heating season. Air sealing works best as part of a broader approach - many homeowners combine it with basement insulation for a complete treatment of the lower part of the house.
We use a blower door test before and after every job to measure your home's actual air leakage - so you have proof the work made a real difference, not just a promise.
If your energy bills feel out of proportion to your home's square footage - especially during Bremerton's long heating season from October through April - air leaks are often the reason. Heat pumps and furnaces are efficient, but they cannot keep up if warm air is constantly escaping through gaps in the attic and crawl space.
Cold air that pools near the floor, especially in rooms above a crawl space, is a strong sign that outside air is getting in from below. In Bremerton homes with crawl spaces - which is most of them - this is one of the most common complaints homeowners describe before getting air sealing done.
That familiar earthy smell that settles into many older Bremerton homes during the rainy season is often a sign that moist outdoor air is being pulled in through gaps in the crawl space or attic. Air sealing those entry points is usually the first step toward getting rid of the smell for good.
Homes built in Bremerton before 1990 were constructed under older codes that did not require today's level of air tightness. If your home has never had a professional energy assessment, there is a very good chance it has significant leaks that have been quietly costing you money for years.
Our air sealing work starts in the attic and crawl space, where the biggest leaks almost always live. We use foam, caulk, and specialized weatherstripping depending on the size and type of each gap. Every job begins with a blower door test that measures how leaky your home is and tells us exactly where to focus. We also check rim joists, plumbing penetrations, electrical chases, and the tops of interior walls - the spots that most general contractors overlook.
Air sealing is often paired with attic air sealing as a standalone service when the attic is the primary problem area, or combined with insulation upgrades for a complete energy envelope treatment. We are also familiar with Puget Sound Energy's rebate requirements and can confirm upfront whether your project qualifies. The ENERGY STAR program and federal tax credits may also apply to qualifying projects.
Best for homes where heat is escaping through the attic floor - typically the highest-impact area in older Bremerton homes.
Best for homes with cold floors and damp smells caused by outdoor air and moisture entering from below.
A complete treatment covering attic, crawl space, rim joists, and wall penetrations - ideal for older homes with multiple leak sources.
Best for homeowners who want to address both heat escape and air movement in a single project for maximum comfort and savings.
Bremerton averages over 50 inches of rain per year and the air stays damp for most of the fall and winter. That persistent moisture finds its way into your home through the same gaps that let cold air in, which is why unsealed homes here tend to feel clammy and smell musty even when the heat is running. A high proportion of Bremerton homes sit on crawl spaces - not full basements - and crawl spaces in this climate are a major source of cold air, moisture, and sometimes mold. Homeowners in Gorst and surrounding communities face the same crawl space challenges.
Many Bremerton homes were built in the 1950s through 1980s, when builders were not thinking about air tightness. These older homes typically have significant gaps around plumbing, wiring, and framing that were never sealed - and they have been leaking air every heating season since. Puget Sound Energy serves most of Bremerton and runs one of the more generous rebate programs in the state for air sealing work. Homeowners across Port Orchard and the wider Kitsap Peninsula can access the same rebates - ask your contractor whether they are enrolled in PSE's approved contractor network. The EPA notes that properly sealed homes also have better indoor air quality because less unfiltered outdoor air - including pollen, moisture, and pollutants - enters through uncontrolled gaps.
We reply within one business day. We ask a few basic questions - your home's age, whether you have a crawl space, and what has been prompting your concern - so we show up prepared and ready to give you accurate answers.
Before any work begins, we run a blower door test that depressurizes your home and measures exactly how much air is leaking and where. This takes about an hour and gives us a precise baseline to compare against after the job is done.
The crew spends most of their time in the attic and crawl space - the two areas where the biggest leaks almost always live. Most of the work happens in spaces you rarely visit, so your daily routine is barely disrupted. Most jobs are completed in a single day.
We run the blower door test a second time after sealing and show you the before-and-after numbers. If your project qualifies for PSE rebates or a federal tax credit, we provide the documentation you need to apply.
Free estimate. No obligation. We include blower door testing in every quote.
(360) 287-4054We run a blower door test before and after every air sealing project. That means you see the actual numbers showing how much tighter your home became - not just a contractor's word for it. If the numbers do not show real improvement, something went wrong and we make it right.
Most Bremerton homes sit on crawl spaces, and crawl spaces in this climate are a primary entry point for cold air and moisture. We treat the crawl space as a priority on every air sealing job - not an afterthought - because skipping it leaves one of the biggest leaks in your home untouched.
We are familiar with Puget Sound Energy's rebate programs and can confirm upfront whether your project qualifies. We also provide the documentation needed to apply for federal tax credits, so you do not have to track down paperwork after the job is done.
The older the Bremerton home, the more air leaks it tends to have - and the bigger the results when those leaks are sealed. We have worked on homes throughout Bremerton and the surrounding Kitsap Peninsula and know exactly where the gaps hide in mid-century construction. The U.S. Department of Energy estimates that properly air-sealing and insulating a home can cut heating and cooling costs by up to 15 percent - and in older homes, the improvement is often even more dramatic.
Testing, crawl space expertise, rebate knowledge, and local experience - each one matters on its own, and together they add up to a job you can verify and a home that performs better from day one.
Insulate your basement walls and rim joists to stop cold air from entering at the foundation level.
