Serving French Valley, CA and surrounding areas. (951) 593-1138
If your AC runs all day but certain rooms never cool down, conditioned air is escaping through gaps you cannot see. We find and seal those leaks - and show you the before-and-after numbers to prove it worked.
Air sealing in French Valley means finding and closing the small gaps, cracks, and penetrations in your home's walls, attic, and floors where conditioned air escapes and hot outside air enters - most jobs on a standard single-family home are complete in one to two days, mostly in the attic and crawl space, with no need to clear your living areas.
In French Valley's climate, where summer afternoons regularly push past 100 degrees, air leaks are more costly than in milder parts of California. Your air conditioner is producing cool air, but if gaps around recessed lights, plumbing penetrations, and attic bypasses are open, that conditioned air exits through the ceiling or walls as fast as the system creates it. Many homes built during French Valley's rapid growth in the 2000s have significant leakage points that were never addressed during construction - and the homeowners have been paying for it on every summer electricity bill since. Air sealing works best when combined with attic air sealing for homes where the attic floor is the biggest leak source, which it usually is in this climate.
A blower door test measures exactly how much air your home is currently losing before any work starts - which means you get real numbers, not a guess, and you can verify the improvement after the job is done.
If your air conditioner seems to run without stopping during French Valley's summer heat but certain rooms never quite cool down, air leaks are a likely cause. Conditioned air is escaping through gaps in the building envelope, and hot attic or outdoor air is replacing it faster than your system can keep up. This is one of the most common complaints from homeowners in the Temecula Valley area, and air sealing often resolves it without any change to the AC unit itself.
On a hot afternoon or a cool winter evening, hold your hand near your attic access panel, around the edges of recessed ceiling lights, or along the top of window frames. If you feel air movement, you are feeling conditioned air escaping or outside air entering. These are among the most common and most fixable leak points in French Valley's tract-home construction.
Unusual dust buildup around recessed lights, electrical outlets on exterior walls, or along baseboards is often a sign that air is moving through gaps in those areas. The moving air carries dust particles and deposits them at the leak point. In French Valley's dry environment - especially during Santa Ana wind events - this pattern is more pronounced and easier to spot than in more humid climates.
Production homes built during French Valley's growth years were constructed quickly and often without careful attention to air sealing details. If your home is in this category and has never been tested, there is a strong likelihood that an audit would find meaningful leaks - particularly around the attic floor, HVAC ducts, and plumbing penetrations. A blower door test costs little or nothing through some utility programs and gives you a clear picture before you spend anything on improvements.
We start every air sealing project with a blower door test - a measurement of how much air your home is currently losing - so you have a baseline before any work begins. The contractor then identifies the highest-priority leak points and seals them using caulk, weatherstripping, or spray foam depending on the size and location of each gap. Most of the work happens in your attic, where gaps around recessed lights, framing, and HVAC penetrations are the biggest sources of loss in French Valley homes. For comprehensive attic work, our attic air sealing service goes through every penetration in the attic floor systematically before any new insulation is added.
After the work is complete, we run the blower door test again. The before-and-after numbers give you concrete proof that the leakage rate improved - not just a promise. Air sealing pairs naturally with basement insulation for homes with below-grade spaces, and with wall insulation for homeowners who want to address every thermal pathway at once. Bundling the work typically reduces the total cost compared to scheduling each service separately.
Measures your home's air leakage rate before and after work - gives you proof the job reduced leakage, not just a promise.
Targets the highest-impact leak points in most French Valley homes - recessed lights, framing gaps, and HVAC penetrations in the attic floor.
Closes gaps around outlets, pipes, and penetrations in exterior walls and floors where conditioned air escapes.
Combines sealing with insulation work in one project - addresses both the thermal barrier and air movement problems together.
French Valley sits in the Temecula Valley area of Riverside County, where summer temperatures regularly climb into the high 90s and occasionally past 105 degrees. When your home leaks air, your air conditioner runs longer and harder to compensate - and in this climate, that shows up fast on your electric bill. Attic spaces in French Valley homes can exceed 150 degrees on summer afternoons. If your attic ceiling has unsealed penetrations, that heat pushes down into your living space continuously. Sealing the attic floor is typically the highest-impact improvement for homeowners here, and it is where we focus first. Homeowners in nearby Wildomar face the same summer heat and the same attic-driven leakage problem.
French Valley is also served by Southern California Edison, which offers rebates for energy efficiency improvements including air sealing and insulation work done together. These rebates can meaningfully reduce your net cost, but they require that the work be done by a participating contractor and that documentation be submitted after completion. Much of French Valley is also in an unincorporated Riverside County area, and for projects that involve more than basic sealing - such as combined insulation and air sealing work - a permit may be required. We know which projects trigger that requirement and handle the paperwork before work starts. Homeowners throughout Menifee and the broader Southwest Riverside County area follow the same permit and rebate process.
We ask a few basic questions - your home's size, age, and what has been prompting your concern. Most requests get a response within one business day. There is nothing you need to prepare for the initial call, and there is no cost to schedule the assessment.
A contractor walks through your home and sets up a blower door - a temporary fan mounted in your front doorway - to measure how much air your home is currently leaking. This takes about an hour and gives both of you a clear baseline. The contractor uses the results to identify the highest-priority areas and give you a written estimate.
Most of the sealing work happens in your attic and, if applicable, your crawl space. You do not need to move furniture or clear living spaces. The crew uses foam, caulk, or weatherstripping depending on the gap size and location. Work typically takes one full day for a standard-sized home.
Once the sealing work is complete, we run the blower door test again and show you the before-and-after numbers. You get concrete proof that the leakage rate improved. If the improvement is less than expected, we investigate before closing out the job. Your home is ready to use normally that same evening.
Free estimate, no pressure. We test your home first, tell you exactly where the leaks are, and give you a written quote before any work begins.
(951) 593-1138A contractor who does this well tests your home before and after the job - not just seals things and leaves. The before-and-after blower door readings give you proof that the work actually reduced air leakage. If a contractor will not provide those numbers, that is a red flag worth taking seriously. We document both tests and share the results with you at the end of every project. See ENERGY STAR for guidance on what to expect from a professional air sealing project.
Most French Valley homes were built during the rapid growth years of the late 1990s and 2000s, and production-built homes of that era share common air sealing deficiencies - attic bypasses around recessed lights, open HVAC chases, and unsealed plumbing penetrations. We have worked on many of these homes and know where to look first, which makes the inspection faster and the results more thorough.
Southern California Edison offers rebates for qualifying air sealing and insulation projects, but capturing them requires documentation and a participating contractor. We walk you through which programs apply to your project, handle the paperwork after completion, and make sure you are not leaving savings on the table. You should not have to spend hours researching rebate requirements on your own.
We reply to every estimate request within one business day - no waiting a week for someone to call you back. We are based in this community and work throughout French Valley and the surrounding Southwest Riverside County area. When you call, you are talking to someone who knows your neighborhood, not a call center routing your request to whoever is available.
