Hidden gaps in your attic and walls leak your cooled air and pull in Salinas Valley dust. We find them, seal them, and test before and after so you can see the real difference.

Air sealing in Soledad means finding and closing the gaps, cracks, and openings in your home where outside air sneaks in and conditioned air escapes - most jobs take two to six hours in a single visit, with no need to leave your home.
The leaks are rarely obvious. The biggest ones are usually hidden in the attic where the walls meet the roof framing, around pipes and wires that pass through walls, and in the crawl space near the foundation. Together these gaps can add up to the equivalent of leaving a window open all year. In Soledad, where summer temperatures regularly push into the 90s, that means your air conditioner runs constantly just to make up for the hot air constantly seeping in.
Air sealing and attic air sealing work alongside basement insulation and wall insulation because they address different problems. Insulation slows heat transfer through materials, but it cannot stop air moving through gaps - only sealing can do that. Doing both at the same time gives you the full benefit.
If your cooling costs feel out of proportion to how much you are running the air conditioner, air leakage is often the reason. When hot outside air seeps constantly through attic and wall gaps, your system has to run almost continuously to keep up. If your bill climbs sharply from June through September in Soledad, it is worth having a contractor check for leaks.
The Salinas Valley's agricultural activity means outdoor air carries real particulate matter. If you are cleaning more than you feel you should have to and notice a gritty film on furniture within a day or two of cleaning, with windows shut, your home may have significant air leakage letting that outdoor air in.
If one bedroom is always stuffy in summer or one corner of the living room is always drafty in winter, that is a sign outside air is getting in somewhere nearby. Uneven temperatures from room to room are one of the most common and most overlooked signs of air leakage in older homes.
On a windy day or cold night, hold your hand near an electrical outlet on an exterior wall, along the baseboard, or near the pull-down attic stairs. If you feel a temperature difference or slight movement, air is passing through the wall cavity. This is a simple test any homeowner can do and a clear signal that sealing work would help.
We start with a diagnostic step - many jobs include a blower door test, where a large fan mounted in the front door depressurizes the house and lets us trace exactly where air is moving using smoke or thermal imaging. This takes the guesswork out of the job and ensures no major leak gets missed. After sealing, we test again so you can see the measured improvement in numbers, not just take our word for it. For targeted attic air sealing - which is where the biggest leaks usually are - we seal the top plates, penetrations around pipes and wires, and the boundary between conditioned and unconditioned space before any insulation goes in above it.
For homes that also need basement insulation or crawl space work, we combine the sealing and insulation into one visit where possible. Doing both together is more efficient and the combined energy benefit is significantly better than either alone. We use foam, caulk, and weatherstripping depending on the location and size of the gap, and we follow California's energy efficiency standards for ventilation so your home still breathes properly after the work is done.
Full assessment and sealing of all major leakage points - attic, walls, crawl space, and around all penetrations.
Best first step for most Soledad homes - targets the top plates and penetrations where the biggest leaks typically live.
Pre- and post-job testing that gives you measurable numbers on how much the work improved your home's airtightness.
Pairing air sealing with insulation installation in one visit for homeowners who want to address both at the same time.
Soledad has a wide temperature swing - summer afternoons regularly hit the 90s while winter nights can drop near freezing. That range means your home is fighting heat gain for months and heat loss for months on the other side. A large share of the city's housing was built before 1990, under standards that did not prioritize keeping air in or out. If your home has never had an energy assessment, it almost certainly has significant leakage that has simply never been found or fixed. Homeowners in Marina and Salinas face similar issues, and we see the same patterns across all of the communities we serve in the region.
The agricultural context matters too. Soledad is surrounded by active farmland, and the air during growing and harvesting seasons carries dust, pollen, and other particulates that find their way indoors through any unsealed gap. Air sealing is not just an energy project for many Soledad households - it also makes the indoor environment cleaner and more comfortable, especially for families with respiratory sensitivities. The Building Performance Institute at bpi.org sets the training standards for this type of diagnostic and sealing work.
We reply within one business day. You will be asked about your home size, whether you have a crawl space or attic, and what is prompting the call. This helps us estimate the job length and whether we need specialized equipment.
Before sealing anything, we assess where the leaks are. Many jobs include a blower door test - we depressurize the house and trace where air is moving. This step usually takes one to two hours and gives us the information needed for an accurate quote.
After the assessment we explain what we found in plain terms - the biggest leaks, what we plan to do about each one, and the total cost. This is the right time to ask about PG&E rebates and whether your project qualifies. No verbal-only quotes.
The crew seals every gap identified in the assessment using foam, caulk, or weatherstripping. Once done, we run a second blower door test so you can see the before-and-after numbers. You receive written documentation to support any rebate application.
Free estimate with no obligation. We test before and after so you see the real numbers - not just a promise.
(831) 315-4493We run a blower door test before the job and again after, so you have actual numbers showing the improvement - not just a promise that the work was done. This is the clearest sign of quality air sealing and the standard any reputable contractor should meet.
Soledad is in PG&E territory, and their Home Energy Upgrade program offers rebates for qualifying air sealing work. We are familiar with what qualifies and what documentation you need to submit. We explain the rebate process before you commit so you know what to expect. ENERGY STAR guidelines for residential energy efficiency, which we follow on every job.
We work in the Salinas Valley and understand that air leakage in Soledad homes is not just an energy issue - it is also an indoor air quality issue. Homeowners here deal with real particulate matter from nearby farmland, and we factor that into how thoroughly we approach sealing every gap.
Air sealing work in California needs to be done with ventilation in mind so homes remain healthy after sealing. We operate under California's energy efficiency requirements and know the difference between a properly sealed home and one that has been over-sealed without accounting for fresh air exchange.
Every one of these points ties back to the same commitment: we do the diagnostic work properly, we seal what needs to be sealed, and we give you the numbers to prove it made a difference.
Target the attic separately where the largest bypasses - top plates, penetrations, and attic hatches - are typically found.
