If your Jerome home is drafty, expensive to heat, or dusty even after cleaning, air leaks are most likely to blame. We find them and seal them - permanently.
Air sealing in Jerome means finding and closing the gaps, cracks, and openings in your home where outside air enters and conditioned air escapes - most jobs for a single-family home are completed in one to two days using a blower door test to locate exactly where the leaks are.
Most homeowners think about windows and doors when they think about drafts, but the biggest leaks are almost always in the attic floor, around plumbing penetrations, and at gaps in the framing. Air sealing services work on all of these at once. If you are also dealing with inadequate insulation in your ceiling or upper walls, pairing air sealing with our attic air sealing service gives you the most complete fix for heat loss at the top of your home.
The U.S. Department of Energy estimates that air leaks account for 25 to 40 percent of the energy used to heat and cool a typical home. Sealing those leaks is one of the most cost-effective improvements available before upgrading equipment.
Jerome winters are cold enough that a leaky home forces your furnace to work constantly just to hold temperature. If your gas or electric bill jumps significantly from October through February and you have not changed your thermostat, that is a strong sign conditioned air is escaping faster than it should.
The Magic Valley is one of the dustiest agricultural regions in Idaho, and fine dust during spring and fall is a fact of life in Jerome. If you find a thin layer of grit on countertops or furniture within a day or two of cleaning - especially during windy weeks - outside air is being pulled through gaps in your home's shell.
If one bedroom or a corner of your living room always feels a few degrees colder than the rest of the house, the problem is usually not your heating system - it is air sneaking through gaps in that part of the home. Hold your hand near electrical outlets on exterior walls on a cold day. If you feel cool air, that gap can be sealed.
Attic hatches and recessed light fixtures in the ceiling are two of the most common air leak locations in older homes. If you can feel cool air dropping from a ceiling light on a cold winter day, or your attic hatch feels cold to the touch, outside air is moving freely through your ceiling - a very common issue in Jerome homes built before the 1990s.
Every air sealing job starts with a blower door test - a diagnostic that depressurizes your home and reveals exactly where and how much air is moving in. This test takes the guesswork out of the work. From there, we target the highest-impact locations: attic floors, crawl space entry points, basement rim joists, plumbing and wiring penetrations, and interior gaps around outlets and light fixtures. For ceiling-level leaks, our attic air sealing service addresses the attic floor specifically and is often the single highest-return improvement in an older Jerome home.
Air sealing and insulation work best together. Insulation slows heat moving through solid materials. Air sealing stops air from moving through gaps entirely. Combining the two - for example, pairing attic air sealing with added insulation above it - is how you get a home that actually holds its temperature. We also offer basement insulation for homes where cold is entering at the foundation as well. After all sealing work is complete, we run a second blower door test to show you the before-and-after numbers.
Best for homeowners who want a full diagnosis and a systematic fix - covers attic, crawl space, and interior penetrations in one project.
Best for homes where the attic is the primary leakage path - seals the top of the thermal envelope where heat rises and escapes first.
Best for homes on a crawl space or with an unfinished basement - stops cold ground air from entering at the foundation and working up.
Best for homes that need both - addresses gaps and adds R-value in the same project so neither improvement is working at a disadvantage.
Jerome sits in the high desert of south-central Idaho, where summer highs regularly push past 95 degrees and winter lows can drop below zero. That 100-degree seasonal swing causes building materials to expand and contract repeatedly, which gradually opens up small gaps in framing, drywall, and trim. For homeowners here, air sealing is not a luxury - it is a practical response to a climate that actively works against a tight home. On top of that, the open plain around Jerome means persistent winds that push cold air into every gap they can find. Homes built before the 1980s were rarely designed with air tightness in mind, and if your home has never had this work done, the savings from doing it now can be substantial. Building Performance Institute (BPI) certification is a credential worth looking for in a contractor who does this kind of diagnostic work.
The agricultural fields around Jerome generate fine dust, especially during spring planting and fall harvest. When your home has significant air leaks, that dust does not stay outside - it gets pulled in through gaps around outlets, light fixtures, and attic penetrations. Sealing those gaps helps keep your indoor air cleaner during the seasons when outdoor air quality is at its worst. We serve homeowners throughout the region, including Gooding and Filer, where the same climate conditions and older housing stock create the same air leakage problems.
Tell us your home's age, approximate size, and what has been prompting your concern - high bills, drafts, or dust. We respond within one business day and can usually schedule an assessment within the week.
We mount a temporary fan in your front door, depressurize the house, and measure exactly how much air is moving in and where. This takes one to two hours and gives you a precise picture of how leaky your home actually is before we quote a dollar of work.
After the assessment, we explain what we found and give you a written estimate before any work begins. This is the right time to ask about Idaho Power rebates and the federal energy efficiency tax credit - we know what is currently available for Jerome homeowners.
The crew works through attic, crawl space, and interior penetrations in a single day for most homes. After finishing, we run a second blower door test and share the before-and-after numbers with you. That measurement is your proof.

(208) 210-4790We run a diagnostic test before we start and again after we finish. Those two numbers tell you in plain terms how much tighter your home has become. You do not have to take anyone's word for it - the measurement is there in black and white.
Idaho requires contractors doing weatherization work to be licensed through the state. We meet that requirement and know what triggers a permit through the Jerome County Building Department - so you are never left with unpermitted work on record.
We participate in Idaho Power's rebate program for qualifying energy efficiency work. That means we handle the paperwork and you are less likely to run into eligibility issues after the job is done. Ask us what the current rebate amounts are for your project.
Homes built before the 1980s in Jerome were never designed with air tightness in mind. We have seen what those wall assemblies and attic floors look like and know where the gaps are most likely to be. That experience means less time on-site and more accurate estimates upfront.
Every air sealing job we do ends with a measurement that shows the improvement. That transparency is how we earn repeat calls from Jerome homeowners and referrals from their neighbors.
