Every gap and crack in your home's envelope lets Dothan's summer heat and humidity push straight in. Air sealing closes those openings so your air conditioner can finally keep up.
Air sealing in Dothan means finding and closing the small gaps, cracks, and openings where outside air sneaks in and conditioned air leaks out - most jobs take one full day and cover the attic floor, crawl space, and penetrations throughout the home. These openings are often invisible: hidden around pipes, behind electrical outlets, and along the edges where walls meet floors. Closing them is one of the most effective ways to make your home more comfortable and less expensive to cool.
Air sealing and insulation work together but do different things. Insulation slows heat from moving through walls and ceilings - air sealing stops air from moving through gaps entirely. Doing one without the other leaves real performance on the table. Many homeowners combine air sealing with basement insulation or attic upgrades to address the full envelope at once.
Homes built in Dothan before the 1990s were constructed with little to no attention to air sealing, and decades of settling have opened additional gaps around pipes, wires, and framing. If your home is more than 30 years old, there is a strong chance it has significant leakage that was never addressed.
If your Alabama Power bill climbs dramatically from June through August and your habits have not changed, your home is likely working against your air conditioner. Dothan's heat and humidity are relentless in summer, and a leaky home forces your system to run longer and harder than it should. A noticeable year-over-year increase in cooling costs is one of the clearest signs that air sealing could help.
If one or two rooms in your home always feel warmer or stuffier than the rest, the problem is often air leakage rather than the HVAC system itself. Hot outside air is finding its way into those spaces through gaps in the ceiling, walls, or floor, overwhelming the cooled air your system is delivering. This is especially common in rooms directly under an attic space or above a crawl space.
Dothan's outdoor humidity is high enough from late spring through early fall that a leaky home will feel muggy even when the air conditioner is keeping the temperature down. If your home feels sticky or clammy indoors, or if you notice condensation forming on surfaces in summer, outside air is getting in faster than your system can dehumidify it.
If your home sits on a crawl space and you have never had it professionally evaluated, there is a strong chance it is contributing to both air leakage and moisture problems. Crawl spaces in Dothan's climate are particularly prone to taking on humid air through foundation vents and gaps around pipes. Musty smells in the lower level of your home are a warning sign worth acting on.
A thorough air sealing job addresses the attic floor, the crawl space or basement rim joists, and the areas around every pipe, wire, and duct that passes through a ceiling or wall. We use foam and caulk applied to the specific gaps found during the assessment - not a general spray of one area. For homes with crawl spaces, which are common throughout Dothan and Houston County, we also recommend pairing air sealing with attic air sealing to address both ends of the home at once.
We use a blower door test before and after the work - this is a fan-based measurement tool that tells us exactly how leaky your home is and confirms the improvement after sealing. A contractor who only caulks around windows and doors without going into the attic is leaving the biggest leaks untouched. The Building Performance Institute sets training standards for energy efficiency professionals that guide the thoroughness of our approach.

Dothan sits in the heart of the Wiregrass region, where summer temperatures climb into the mid-90s and humidity stays high from May through September. That combination means your air conditioner runs almost constantly for months at a time, and every gap in your home's envelope lets hot, sticky air push straight in. Homeowners here feel the impact of air leaks more acutely than people in milder climates - and the savings from sealing those leaks show up faster on the monthly power bill. Many of the homes in Dothan's established neighborhoods were built in the 1960s through 1980s, before energy efficiency was a standard consideration in residential construction.
High humidity in Dothan creates an additional reason to hire someone with local experience. Sealing a home without also managing moisture can trap humidity inside the building envelope and create mold in attic spaces. A contractor who works regularly in this region knows how to seal a home in a way that handles this climate correctly. We serve homeowners in Phenix City, AL and Eufaula, AL where the same humid climate conditions make thorough air sealing a high-value upgrade for any older home.
When you reach out, we will ask a few basic questions - the age of your home, whether it has a crawl space, and what problems you have been noticing. We respond within 1 business day and will not pressure you to commit to anything before we have seen your home.
We walk through your home, inspect the attic and crawl space, and use a blower door test to measure exactly how leaky your home is. This gives you a real, measurable starting number - not a guess - so you can see the improvement after the work is done.
The crew spends most of their time in the attic and crawl space, applying foam and caulk to seal the gaps found during the assessment. Most of the activity happens out of sight. Expect the job to take most of a full day for a typical Dothan home.
We run the blower door test again after the work is done so you can see the measurable improvement in writing. We walk you through what was sealed and provide documentation for any federal tax credit or utility rebate you plan to claim.

A large share of homes in Dothan and Houston County sit on crawl spaces - one of the most common air leakage sources in this region. We have experience sealing crawl spaces in the specific humidity conditions of southeast Alabama.
We run a blower door test before and after the work so you have a real number showing what changed - not just a receipt. This is the difference between knowing the job worked and hoping it did.
Air sealing in a humid climate like Dothan's requires knowing which gaps to prioritize and how to seal them without trapping moisture inside the building envelope. We work in this climate every day and choose materials accordingly.
Federal tax credits for qualifying air sealing work are available - as of 2025, homeowners may qualify for a credit worth up to $1,200 under the IRS Energy Efficient Home Improvement Credit. We provide the documentation your tax preparer needs to apply it correctly.
