Gaps in your home let in cold marine air, agricultural dust, and wildfire smoke. We find every leak with a blower door test, seal them, and prove the improvement with a second test before we leave.
Air sealing services in Nipomo, CA close the hidden gaps in your home's walls, attic, and crawl space where outside air enters and conditioned air escapes, and most jobs on a standard single-family home are completed in one to two days with no demolition or major disruption.
Insulation slows heat transfer, but it does not stop air movement. If your home has gaps around outlets, light fixtures, attic penetrations, or where pipes and wires enter walls, outside air flows right through those openings and carries heat with it - bypassing the insulation entirely. In Nipomo, where cool marine air rolls in most evenings and agricultural dust blows through during dry periods, those gaps are working against you every day.
Air sealing works best when paired with basement insulation or attic air sealing to create a complete thermal envelope - one where heat moves slowly through insulated surfaces and cannot sneak out through unsealed gaps at the same time.
If you have noticed the smell of wildfire smoke inside your home during fire events - even with all windows and doors closed - that is a direct sign that outside air is finding its way in through gaps in your home's structure. San Luis Obispo County, including Nipomo, has seen increasing smoke events. A home that lets smoke in is also letting in cold air and agricultural dust year-round.
Nipomo's marine layer brings cool air in from the coast most evenings. If you feel a chill near interior walls or in certain rooms even with the heater on, that is air infiltration - not a heating system problem. Gaps around outlets, light fixtures, and where pipes enter walls are the most common culprits in homes from the 1970s through 1990s.
Nipomo's weather is genuinely temperate. If your heating and cooling costs feel out of proportion to the mild conditions here, air leakage is one of the most common explanations. A home constantly losing conditioned air through gaps has to run its system much harder to stay comfortable, and that shows up directly on the utility bill.
The Santa Maria Valley and surrounding farmland generate significant agricultural dust, especially during dry and windy periods. Homes with unsealed gaps pull that dust in through every crack and deposit it on surfaces. If you are dusting more than you should be, or if family members with allergies have more symptoms at home than elsewhere, air infiltration through unsealed gaps is often the reason.
The most impactful air sealing work in most Nipomo homes happens in the attic, where gaps around top plates, recessed lights, and pipe and wire penetrations account for a disproportionate share of total air leakage. We address those first, then move to the crawl space and the wall penetrations that are contributing to drafts in living areas. Our whole-home approach is especially effective when combined with attic air sealing to address ceiling-level gaps that are often the biggest source of heat loss.
For homeowners who want to address insulation and air leakage in the same visit, we regularly combine air sealing with basement insulation to create a complete lower-envelope solution. Doing both at once is more cost-effective than scheduling separate jobs, and the combined result is dramatically better comfort than either service delivers on its own.
Sealing gaps at top plates, around recessed lights, and where pipes and wires penetrate the attic floor - the highest-impact area in most Nipomo homes.
Closing gaps around floor penetrations and rim joists to stop cold, damp air from entering living spaces from below.
A blower door test identifies every significant leak in the home, and we address them all in a single visit - from the attic to the foundation.
Nipomo sits on the coastal mesa where marine air cycles in from the Pacific most mornings and evenings, creating a constant pressure difference across your home's shell. That daily temperature cycling - warm afternoons, cool nights - means gaps and cracks in your home's structure work harder here than in a stable inland climate. The Nipomo Valley's surrounding farmland adds another layer: fine agricultural dust moves through the area during dry and windy periods, and any unsealed gap becomes an entry point. Homes built in the 1970s through the 1990s - the dominant age range in Nipomo - were constructed before California's modern energy codes required tight building practice, and their gaps have been accumulating for decades. A significant portion of those homes have never been professionally air sealed.
Beyond comfort and dust control, wildfire smoke is now a regular seasonal concern for San Luis Obispo County homeowners. A well-sealed home provides meaningful protection during smoke events that a leaky home simply cannot. We work throughout Grover Beach and Pismo Beach as well, where coastal conditions and older housing stock create the same pattern. The U.S. Environmental Protection Agency notes that air sealing is one of the most effective steps a homeowner can take to improve indoor air quality - a point that resonates especially strongly in areas with agricultural dust and wildfire smoke exposure.
We ask about your home's age, layout, and what is prompting the call. We reply within one business day and schedule a diagnostic assessment rather than quoting blindly over the phone.
We run a blower door test that measures your home's current air leakage rate and helps pinpoint where the biggest gaps are. This step is what separates a thorough job from guesswork - you get a real number, not an estimate.
Most of the work happens in the attic, crawl space, and around mechanical systems - not in your living areas. We spray foam into gaps, apply caulk around penetrations, and seal around fixtures. A standard home is typically completed in one day.
We run a second blower door test after the work so you can see the before-and-after numbers in writing. You also receive documentation of what was done, which is useful for rebate applications or home resale.
Free written estimate. Diagnostic testing included. We reply within one business day.
(805) 723-9619We test before the work begins and again after it is complete, so you have a real number showing how much the leakage rate improved. This is how you know the work made a difference - not because we say so, but because the data shows it.
Air sealing for wildfire smoke protection is not a new topic for us - it is something Nipomo homeowners ask about regularly. We know which gaps matter most for keeping smoke out and focus on those first during every assessment in this area.
Nipomo is in PG&E territory, and qualifying air sealing work may be eligible for utility rebates. We provide the documentation you need to apply and can walk you through what is currently available before the job starts.
The Nipomo Valley's farmland generates fine particulates that enter homes through every unsealed gap. We address the gaps that matter most for dust infiltration, and many homeowners notice a difference in how much they are dusting within weeks of the work being done.
Air sealing is one of those projects where the results are measurable and immediate - you can see the before-and-after numbers, and you will feel the difference on the first cool evening after the work is done. The Building Performance Institute sets the standard for diagnostic testing and verified installation in home energy work, and the process we follow is built around that standard so you have proof the job was done right.
Targeted sealing at the attic level, where gaps around top plates and penetrations account for most of a home's air leakage.
