Hidden gaps in your attic, crawl space, and walls let warm air out and damp coastal air in. We find every leak with diagnostic testing and seal them before they cost you another winter.
Air sealing in Marina means locating and closing the hidden gaps in your home's envelope - around plumbing, electrical penetrations, attic floors, and rim joists - that let outside air move freely in and out. A thorough job typically takes one to two days and includes a blower door test before and after so you can see in measurable terms exactly how much leakage was reduced.
Insulation slows heat loss through materials, but it does not stop air movement. In Marina, where the marine layer drives cool, damp air against homes for hours every morning, those hidden gaps are responsible for a meaningful share of your heating costs. Air sealing closes the pathways insulation cannot reach. It pairs naturally with our basement insulation work, since rim joists and foundation gaps are among the most common leakage points in older homes.
Most homeowners notice the difference immediately - the drafts disappear, rooms even out, and over the following months the energy bill follows. If your home was built in one of Marina's Fort Ord-era neighborhoods, the leakage has likely never been addressed, and the improvement after sealing is often dramatic.
If certain rooms feel drafty or noticeably cooler than others - especially near the floor or along exterior walls - outside air is getting in. In Marina, this shows up most clearly on foggy mornings when the marine layer rolls in and temperatures drop quickly. It is not a sign the heater is broken; air is bypassing your heating system entirely through gaps in the structure.
Marina's weather is genuinely temperate, so if your gas or electric bill feels high compared to what neighbors pay, air leakage is a likely culprit. A home that leaks a lot of air forces your heating system to run almost constantly just to maintain a comfortable temperature - even when it is only 55 degrees outside. An air leakage assessment is a reasonable first step.
Because Marina sits on the bay, outside air is often heavy with moisture. If that damp air infiltrates through gaps in the attic floor, crawl space, or wall penetrations, it creates a faint musty odor - particularly in the morning before the house warms up. This is not always a mold problem, but it is a sign that outside air is moving through your home in ways it should not be.
If you find yourself dusting more than seems reasonable, or notice dust lines forming along baseboards or around electrical outlets on exterior walls, air is moving through gaps in your home's structure. Air carries dust with it, and the places where it enters leave visible traces over time. Run your hand along the bottom of exterior walls on a cool, windy day and feel for any air movement.
Air sealing is rarely a single task - it is a systematic process of finding every pathway outside air uses to enter your home and closing each one properly. We start with a blower door test that maps your home's leakage, then work through the attic floor, rim joists, plumbing and electrical penetrations, and any crawl space entry points. Materials match the gap - small cracks get caulk, larger openings in the attic get spray foam. We run a second blower door test after the work so you can see the improvement in a real number, not just feel it. This pairs naturally with our attic air sealing service for homes where the majority of leakage is overhead.
For older Marina homes, air sealing often uncovers the need for additional insulation in the same areas - and we can handle both in one visit. Our basement insulation service addresses the foundation and rim joist areas that are among the most common leakage sources in Fort Ord-era construction. We will always tell you what we find and what we recommend before we start any additional work.
Best for homeowners who want a comprehensive fix - every leakage point addressed in one project with before-and-after testing to confirm results.
Suited for homes where the attic floor is the primary leakage pathway - common in Marina's older single-story housing stock with accessible attic hatches.
Targets the gap where the floor meets the foundation - one of the most overlooked leakage sources in Fort Ord-era homes and a major contributor to cold floors.
For homes that need both - sealing and insulation done in the same visit so you address the full problem without scheduling two separate projects.
Marina sits directly on Monterey Bay and lives under a marine layer for much of the year. That persistent coastal moisture does not just make the mornings feel cold - it also means any gap in your home's envelope is an entry point for damp air that can contribute to musty smells, condensation, and gradual wood rot in framing and sills. Air sealing is especially valuable here because it limits how much of that coastal air can infiltrate your living spaces in the first place. The former Fort Ord housing stock, which makes up a large portion of Marina's neighborhoods, was built before modern energy codes existed and typically has significant leakage in the attic, around plumbing penetrations, and along rim joists. If your home is in one of these neighborhoods, there is a very good chance it has never been air sealed.
We serve homeowners throughout the area, including in Pacific Grove and Seaside, where the same coastal climate and similar housing stock create the same air sealing needs. California Title 24's energy code, one of the strictest in the country, applies to any permitted renovation in Marina - a contractor who is familiar with these standards protects you from compliance problems down the road. The U.S. EPA's guidance on indoor air quality and the Building Performance Institute set the diagnostic and installation standards we follow on every job.
We reply within one business day. A brief conversation about your home's age, size, and what you have been noticing helps us show up prepared. You do not need to know where the leaks are - that is what the assessment is for.
A trained technician walks through the attic, crawl space, and main living areas, then runs a blower door test to measure exactly how much air your home is leaking and pinpoint where. The assessment takes one to two hours and gives us a clear picture before we recommend anything. You receive a written estimate afterward - not just a number over the phone.
The crew works primarily in the attic, crawl space, and around mechanical penetrations - spaces you rarely visit. The work is not loud, and most homeowners go about their normal day. A typical job takes one full day, occasionally two for homes with significant leakage or difficult access.
We run a second blower door test after the work is complete so you can see in a real number how much leakage was reduced. We walk you through what was done, provide photos of work areas if you want them, and handle any PG&E rebate paperwork on your behalf. You leave the conversation knowing exactly what changed.

(831) 946-0764We run a blower door test before the work begins and again after it is done. That gives you a concrete measurement of how much the leakage was reduced - not just our word that it went well. A contractor who skips this step is guessing, not solving the problem, and you have no way to verify the work was actually done.
We have worked on Marina's mid-century military housing throughout the city and know the leakage patterns these homes share - attic floor gaps, unsealed rim joists, and penetrations around plumbing that have never been touched. That familiarity means we find the problems faster and seal them more completely than a crew coming in blind.
Marina homeowners who qualify for PG&E's home energy efficiency rebates can only access those rebates through a participating contractor. We are enrolled in the program and handle the paperwork on your behalf - so you do not miss money you are entitled to because of an administrative step you did not know was required.
California's C-2 Insulation and Acoustical Contractor license is required to legally perform this type of work in the state. You can verify any contractor's license number on the CSLB website before you hire anyone. Licensing requires passing background checks and maintaining insurance - not just showing up with a blower.
Every air sealing job we do in Marina ends with documented results and a walkthrough - so you can see what was done, where it was done, and how much it improved. That accountability is what separates a real contractor from someone who just sprays foam in the obvious spots and sends you a bill.
