Serving Seaside, CA and surrounding areas. (831) 315-4007
Seaside's coastal fog finds every gap in your home. Air sealing closes those gaps so cold, moisture-laden air stays outside where it belongs - and your heating costs stop climbing.
Air sealing services in Seaside, CA means finding and closing the gaps, cracks, and hidden openings in your home where outside air sneaks in and conditioned air leaks out. A contractor uses foam, caulk, and weatherstripping to close those openings - and most jobs on a typical single-family home are done in one to two days.
In a coastal city like Seaside, air leakage is not just an energy problem - it is a comfort and moisture problem. The marine layer that rolls in off Monterey Bay most mornings pushes cold, damp air through every unsealed gap in your home's structure. If you have ever noticed your home feeling clammy despite running the heat, or rooms that never quite warm up, air leakage is very likely part of the reason. Many Seaside homes were built in the 1950s and 1960s with gaps that were simply never addressed. Pairing air sealing with basement insulation or other upgrades gives you the most complete result. For homes where the attic is the main concern, dedicated attic air sealing is also available as a focused service.
Seaside's marine layer pushes moist air through gaps in your home's structure. If you notice a persistent damp feeling - especially on foggy mornings - outside air is getting in. Over time, that moisture can cause mold and degrade your insulation, so it is worth addressing before it becomes a larger problem.
If a bedroom, hallway, or corner of your living room is noticeably colder than everywhere else, that space almost certainly has more air leaks nearby. In older Seaside homes built in the 1950s and 1960s, this is extremely common because original construction left gaps around framing, pipes, and electrical boxes that were never sealed.
Hold your hand near an electrical outlet on an exterior wall on a cool day. If you feel air moving, that outlet connects to a gap that goes straight to the outside. This is one of the easiest leaks for a homeowner to detect without tools, and a reliable sign that similar gaps exist throughout the house.
If your PG&E bill consistently runs higher than what friends or neighbors in comparable homes pay, air leakage is one of the first things worth investigating. Heating a leaky home is like filling a bucket with holes - your system runs longer to maintain the same temperature. A blower door test can confirm whether leakage is the culprit before you spend money on other upgrades.
A thorough air sealing job starts with a blower door test - a fan-based tool that measures how much air your home is currently leaking and tells us exactly where to focus. From there, we work through your attic, crawl space, and any interior penetrations like pipes, wires, and recessed lights, applying foam or caulk at every gap we find. For Seaside homes where the crawl space is a major source of cold air and moisture, we include that area as part of the job - not as an optional add-on. We also pair air sealing naturally with basement insulation when both are needed.
After the work is done, we run a second blower door test so you can see the before-and-after numbers. That measurement tells you the work was real, not just the contractor's word for it. For homes where the primary concern is the attic specifically, our dedicated attic air sealing service focuses on that area with the same level of thoroughness.
Best for homes with multiple drafty areas or persistent comfort complaints - covers attic, crawl space, and all interior penetrations in one job.
A focused service for homes where the attic floor is the primary source of heat loss - particularly effective when combined with attic insulation upgrades.
Suited for Seaside homes on raised foundations where cold floors, musty smells, and coastal moisture enter primarily from below.
Includes before-and-after blower door measurements so you have documented proof of the improvement - useful for rebate applications and peace of mind.
Seaside sits on Monterey Bay, and the marine layer that rolls in most mornings is not just a nuisance - it pushes cold, moisture-laden air through every gap in your home's envelope. Unlike inland California cities where the main problem is summer heat, Seaside homeowners deal with persistent low-level dampness and chill that makes unsealed homes feel clammy and drives up heating costs year-round. Air sealing here is not a seasonal fix; it is a year-round comfort upgrade. Homes built near Fort Ord in the 1950s through 1970s were constructed to standards that left many gaps simply never addressed. Homeowners in Del Rey Oaks and Sand City face the same coastal conditions and benefit from the same work.
Crawl spaces are common in Seaside's older homes, and they are one of the biggest sources of cold air and moisture infiltration. A thorough air sealing job in this city almost always includes the crawl space. Rebates are also worth knowing about - PG&E serves Seaside, and California has state-level programs that can offset part of the cost. The U.S. Department of Energy estimates that sealing and insulating can cut energy costs significantly for leaky homes, and older coastal construction tends to show the biggest improvements. The ENERGY STAR program provides additional guidance on what a properly sealed home should look like.

We walk through your home, check your attic and crawl space, and run a blower door test. This measures exactly how much air your home is leaking and shows us where the biggest gaps are - so you are not paying for guesswork.
You receive a written estimate breaking down every area being sealed, the materials being used, and the total cost. We also walk you through any PG&E or California rebates you may qualify for before you sign anything.
The crew works through your attic, crawl space, and all interior penetrations. After the work is done, we run a second blower door test and show you the before-and-after numbers - then walk you through everything that was sealed.

(831) 315-4007Many Seaside homes sit on raised foundations, and the crawl space is one of the biggest sources of cold air and moisture. We include crawl space sealing as part of every whole-house job - not as an extra line item - because leaving it out produces an incomplete result.
We run a blower door test before we start and again when we finish. You see the numbers - not just the contractor's word that the work was done. This documentation also helps with rebate applications through PG&E and California efficiency programs. The Building Performance Institute recognizes this testing standard as the professional benchmark for air sealing work.
Homes built in the 1950s and 1960s in Seaside have their own construction patterns - gaps around framing, uninsulated walls, and crawl spaces that were never properly sealed. We have worked in these homes and know where the leaks typically hide. That experience means a faster, more complete job than a contractor seeing these homes for the first time.
California and PG&E both offer money back for qualifying air sealing work, and most Seaside homeowners do not know what they are eligible for until someone walks them through it. We research available rebates upfront - so the final price reflects every dollar you are owed, not just the sticker price on the estimate.
When you add those points together, the result is simple: you get a contractor who measures the problem before starting, fixes all of it, proves the results, and makes sure you are not leaving money on the table. That is what air sealing in Seaside should look like.
