Serving Rohnert Park, CA and surrounding areas. (707) 210-9475
Hidden gaps in your home let conditioned air out and outside air in - including wildfire smoke. We find every leak and seal it, then prove it worked with a before-and-after test.
Air sealing in Rohnert Park means finding and closing the gaps, cracks, and openings where outside air enters your home and conditioned air escapes, with most single-family jobs completed in one to two days using diagnostic testing before and after the work.
Most leaks are not around windows and doors - they are in the attic floor, around plumbing penetrations, and where walls meet ceilings. In Rohnert Park's planned-community homes built in the 1960s and 1970s, these gaps were simply never addressed during original construction. If your PG&E bills seem high for no obvious reason, or certain rooms never feel quite right, air leakage is usually a contributor. We pair air sealing with basement insulation and other envelope improvements for homeowners who want to address the whole picture at once.
For Rohnert Park homeowners, air sealing also serves as a meaningful barrier against wildfire smoke during Sonoma County fire seasons. A tighter home keeps outdoor air - and what is in it - out more effectively. We address ventilation at the same time so your indoor air quality stays healthy after sealing.
If your utility bill keeps rising and you have not added new appliances or changed habits, air leakage is one of the most common culprits. Your heating and cooling system works harder to replace conditioned air that is escaping. This is especially common in Rohnert Park's older planned-community homes, where original construction left gaps that have only grown over decades of settling.
If one bedroom is noticeably warmer than the rest of the house in July, or a corner of your living room never warms up in January, that inconsistency often points to air leakage nearby. Rohnert Park's wide seasonal temperature swings - hot summers, cool winters - make these comfort problems hard to ignore.
Hold your hand near an electrical outlet on an exterior wall on a cold or windy day. If you feel air moving, that is a direct leak path from outside into your living space. The same test works near baseboards and around frames of doors leading to a garage or attic. Small gaps individually, but significant added up over a full day.
If you noticed smoke smell inside your home during recent Sonoma County fire seasons even with windows closed, your home has meaningful air leakage. A well-sealed home creates a much stronger barrier against outdoor air - including smoke, pollen, and vehicle exhaust from nearby Highway 101.
Every air sealing job starts with a blower door test - a diagnostic tool that pressurizes your home and reveals exactly where air is moving. We map the leaks before we seal anything, so no significant gap gets missed. Depending on where the leaks are, we use caulk, weatherstripping, or spray foam - each one the right tool for a different type of gap. Most of the work happens in the attic and crawl space, out of sight. Our attic air sealing service focuses specifically on the attic floor, where the biggest leaks tend to hide in older homes.
We also address ventilation as part of the job. A well-sealed home needs controlled fresh air so indoor air quality stays healthy. For homeowners dealing with basement insulation needs at the same time, we can combine both scopes into a single visit and often reduce overall project cost. After sealing is complete, we run the blower door test again and give you both numbers in writing.
Best for any homeowner who wants to know exactly where their home is losing air before committing to any work.
Suited for Rohnert Park homes built before 1980 where attic bypass gaps are common and often the largest single source of leakage.
Ideal for homes with a raised foundation where cold, damp air enters from below and works its way into living areas.
Recommended for homeowners who want a comprehensive approach - attic, walls, crawl space, and penetrations all addressed in one project.
Rohnert Park was built out quickly in the 1960s and 1970s as a planned community, and most of that original housing stock is now 50 to 60 years old. Homes of that era were not designed with energy efficiency in mind - attic bypasses, unsealed wall cavities, and gaps around original plumbing are standard findings during diagnostic tests on these properties. Rohnert Park's Mediterranean climate makes the stakes real: summers push into the 90s and winter nights drop into the 30s, so a leaky home is uncomfortable and expensive in both directions. Unlike milder coastal cities, Rohnert Park homeowners feel the impact of air leakage year-round.
Wildfire smoke is a genuine local concern after several significant fire events in Sonoma County in recent years. A well-sealed home keeps smoke particles out far more effectively than a leaky one. PG&E serves Rohnert Park and offers rebates for qualifying air sealing work - we can help you access those programs as part of your project. We work throughout the area, including Petaluma and Sonoma, so scheduling is easy for homeowners across Sonoma County.
We respond within one business day. We ask a few questions - your home's age, whether you have noticed comfort problems, any recent energy work - so we can schedule the right amount of time for your diagnostic visit.
We mount a temporary fan in a doorway, pressurize the house, and use that pressure difference to map exactly where air is moving. This takes about an hour and gives both of us a clear picture of your home's leaks - before we recommend any work.
Based on the diagnostic, we give you a written estimate explaining what we plan to seal, where, and with what material. This is also the right moment to discuss PG&E rebates and federal tax credits - we know the paperwork requirements and can help you apply.
Most sealing happens in the attic and crawl space - your living areas stay undisturbed. When the work is complete, we run the blower door test again. You get the before-and-after numbers in writing so you can see the measured improvement.
Free estimate, diagnostic testing included, no-pressure approach. We respond within one business day.
(707) 210-9475We run a blower door test at the start of every air sealing project and again when the work is done. You receive both sets of numbers in writing - a measurable result, not just our word that it worked. Few contractors in the area include this as standard practice.
A significant share of our air sealing work is in Rohnert Park's older planned-community neighborhoods, where we routinely find open chases around plumbing stacks, unsealed top plates, and recessed light bypasses that were never addressed. We know exactly where to look in these homes.
Sealing a home too tightly without addressing ventilation can trap moisture and indoor pollutants. We check your ventilation as part of every job and flag any issues before we seal - especially important in Sonoma County, where wildfire smoke has made indoor air quality a real concern for many families.
We are familiar with PG&E's energy efficiency rebate programs and can help make sure your project is documented correctly so you actually receive the rebate dollars you are entitled to. The{" "}Building Performance Institute (bpi.org) and ENERGY STAR both set benchmarks that guide our work and support rebate eligibility.
Diagnostic testing, clean workmanship, and transparent results are the standard for every air sealing job we take on in Rohnert Park - not extras you have to ask for.
