Serving Cerritos, CA and surrounding areas. (626) 517-0609
Gaps and cracks in your home let cooled air escape all summer and let outside air push in during Santa Ana events. We find every leak, seal it, and prove the results with a before-and-after test.
Air sealing in Cerritos means finding and closing the gaps, cracks, and openings where outside air sneaks in and conditioned air leaks out, most jobs completed in one to two days, with results you can measure before the crew leaves. These gaps are often hidden in places you would never think to look - around recessed lights, behind electrical outlets, in the attic floor where plumbing pipes meet the ceiling framing.
Most Cerritos homes were built between the 1960s and 1980s, before California had meaningful energy efficiency requirements. That means attic bypasses, unsealed wall top plates, and gaps around plumbing penetrations are extremely common - and they have likely been quietly driving up your energy bills for years. Air sealing pairs naturally with our basement insulation and attic air sealing services, since addressing the full envelope at once produces the most noticeable improvement.
Insulation slows heat transfer through your walls and ceilings, but it does not stop air from moving through gaps. Air sealing handles the gaps. Together, they do a job that neither can do alone - and doing both in the same visit saves time and often reduces the combined cost.
If one or two rooms always feel too warm in summer or too cool in winter - even when the rest of the house is fine - conditioned air may be escaping before it reaches those spaces. In Cerritos, where summer afternoons can push into the 90s, a bedroom that stays stuffy despite the AC running is one of the most common complaints that leads homeowners to call an air sealing contractor.
If your electricity or gas bills seem out of proportion to how much you are running your heating and cooling, air leaks are a likely culprit. Homes built in Cerritos during the 1960s and 1970s were not designed with energy efficiency in mind, and decades of settling can open up gaps that were not there when the house was new.
When outside air infiltrates through small gaps, it brings dust, pollen, and particulates with it. If you find yourself dusting more often than seems reasonable, or if family members with allergies notice their symptoms are worse indoors, air leaks may be the reason. This is especially noticeable in Cerritos during Santa Ana wind events, when dry dusty air pushes through any opening it can find.
Hold your hand near an outlet on an exterior wall on a windy day. If you feel a slight draft, that outlet is connected to the outside through gaps in the wall cavity. The same test works near recessed ceiling lights and along the top of interior walls. These are exactly the kinds of penetrations a professional air sealing job targets.
Every job starts with a diagnostic blower door test - a large fan temporarily mounted in your front doorway that depressurizes the house and makes leaks detectable. This gives us a map of where to focus, not just a guess. We then seal every penetration found using foam for larger irregular gaps and caulk for smaller cracks. We also provide our specialized attic air sealing service when the attic is the primary problem area - which it often is, since the attic floor is where most air loss happens in Cerritos homes of this era.
When you are also upgrading insulation, combining both services in one visit is the most efficient approach. Our crew handles air sealing and basement insulation in the same project when applicable, since the basement rim joist is another common air leak point. At the end of the job, we run the blower door test again and give you both readings in writing - before and after - so the results are documented, not just a claim.
Best for homeowners who want a data-driven map of every leak before committing to a scope of work.
Best for homes where the attic floor has significant gaps around plumbing, wiring, and framing - the most common source of air loss in Cerritos homes.
Best for homeowners who want a comprehensive treatment of all penetrations throughout the house in a single visit.
Best for homeowners ready to address both air infiltration and heat transfer at the same time, usually at a lower combined cost than scheduling separately.
Cerritos sits in the eastern Los Angeles Basin, where summer temperatures regularly climb into the upper 80s and 90s, and marine layer mornings can leave homes feeling damp and cool even in July. That temperature swing, combined with Santa Ana wind events in fall and winter, means air leaks cause discomfort in both directions throughout the year - not just one season. Most Cerritos homes were built between 1960 and 1980, before California had meaningful energy efficiency requirements, which means attic bypasses and unsealed penetrations are the rule rather than the exception. Homeowners in Compton face the same era of construction and the same air sealing needs, and we serve those homes with the same diagnostic approach.
Both Southern California Edison and SoCalGas serve Cerritos residents, and both have historically offered rebate programs tied to energy efficiency improvements including air sealing. Availability changes periodically - ask your contractor or check directly with your utility before scheduling. California also enforces detailed energy codes, so if you are combining air sealing with a permitted renovation, your contractor needs to be familiar with those requirements. We work regularly in Buena Park and neighboring communities throughout this part of Los Angeles and Orange counties. The Building Performance Institute sets the industry standard for diagnostic air sealing work - you can learn more about what certified work looks like at bpi.org.
Reach out by phone or contact form and we will respond within one business day. We ask about your home's age and what is prompting the call, then schedule a time to come assess the situation before quoting anything.
We set up the blower door test to map your home's air leaks, then walk you through what we found in plain terms. The written estimate breaks down what will be sealed, where, and why - no pressure to sign the same day.
The crew spends most of their time in the attic and crawl space applying foam and caulk at every penetration identified during the assessment. You can go about your normal day - the work is not loud, and there is no strong odor in your living spaces.
At the end of the day, we run the blower door test again and hand you both readings. You have documented proof of what changed. If something does not feel right after a week, we come back and check.
Free estimate, written quote, results documented in writing. We reply within one business day.
(626) 517-0609We run a blower door test before and after every air sealing job. That means we know where every significant leak is before we start, and you have documented proof the work made a measurable difference when we are done. No guessing, no spot-treating obvious areas and calling it a day.
Cerritos was built out rapidly during this era, and the air sealing challenges in homes of that period are predictable and well-understood. We know where to look - attic bypasses, top plates, rim joists, plumbing chases - and we address all of them, not just the ones that are easy to reach.
We work in this part of Los Angeles County year-round and know how much those fall and winter wind events affect homes here. Air sealing is one of the most effective ways to reduce how much your home is affected by pressure-driven air infiltration during a Santa Ana event - and we prioritize getting it done before the next one.
We are familiar with the rebate programs offered by Southern California Edison and SoCalGas, and we can help you understand what is currently available before you commit. The ENERGY STAR program also provides guidance on qualifying work - which matters when you are filing for a rebate.
Choosing an air sealing contractor comes down to one thing: whether they do the diagnostic work to find every significant leak or just apply foam where it is easy. We do the full diagnostic job, document the results, and stand behind the outcome.
