Florence summers are long and humid. If hot outside air is sneaking into your home through hidden gaps, your AC can never fully catch up. We find and seal those pathways so your home actually holds the temperature you set.
Air sealing in Florence, AL means finding and closing every gap, crack, and opening in your home where outside air can sneak in and conditioned air can leak out - most jobs take one to two days and do not require tearing anything apart.
Most air leaks in a home are invisible - they are behind your walls, in the attic floor where pipes and wires punch through, and around the framing that sits on top of your foundation. Florence homes built before the 1990s were not designed with air tightness in mind, and decades of settling have made those gaps worse. Your insulation can only do so much if hot, humid outside air is still moving freely through your home.
Air sealing works best as part of a complete energy plan. If your attic also lacks adequate coverage, pairing this service with basement insulation or our dedicated attic air sealing service addresses the biggest leaks together in one visit.
If your electric bill spikes every June and you have not changed your habits, your home is likely letting in more hot air than it should. Florence summers are long and humid, and an air conditioner fighting a leaky house runs almost constantly. A bill that feels too high for the size of your home is one of the clearest signals.
When outdoor humidity sneaks in through gaps and cracks, your AC can cool the air but struggle to dry it out. If certain rooms feel clammy even when the thermostat reads the right temperature, humid outside air is getting in somewhere. This is a very common complaint in Florence homes with crawl spaces.
Hold your hand near an electrical outlet on an exterior wall on a hot or cold day. If you feel air moving, that outlet connects to a gap in your home's outer shell. This is one of the easiest ways to spot air leakage without any equipment, and it is surprisingly common in Florence homes built before the 1990s.
Florence homes on crawl spaces sometimes develop a faint musty smell that seems to come from the floor. This usually means humid air from the crawl space is migrating upward through gaps in the subfloor. Left unaddressed, that moisture can encourage mold growth - a sign worth acting on sooner rather than later.
Florence Insulation uses a blower door test to find exactly where your home is leaking before we touch anything. A large fan mounted in your front door depressurizes the house, pulling air through every crack - we then trace the leaks with a thermal camera and seal each one with spray foam, caulk, or weatherstripping depending on where it is. This systematic approach means we are closing the leaks that actually matter, not just applying foam at random and hoping for the best. You get before-and-after measurements on paper, so you know the work made a real difference.
For Florence homes with crawl spaces - which is most of them - the crawl space is typically the highest-impact area. Humid air from the ground migrates upward through the floor constantly unless those pathways are sealed. We also address the attic floor, rim joists, and every pipe and wire penetration throughout the house. If your project includes both air sealing and insulation, our basement insulation service handles the rim joist and foundation areas, while our dedicated attic air sealing service goes deep on ceiling bypasses and top-plate penetrations above your living space.
The starting point for any serious air sealing job - measures how leaky your home actually is before work begins.
Best for homes where heat from the attic is bleeding through ceiling penetrations into living spaces.
Suits Florence homes on crawl space foundations where ground moisture and air leakage are ongoing problems.
Addresses the band of framing at the top of the foundation wall where air entry is commonly overlooked.
Closes the gaps around every pipe, wire, and duct that runs between floors or through the building envelope.
The most effective approach for older Florence homes where both air leaks and missing insulation need to be addressed together.
Florence is in the Tennessee Valley, where summers are long and humid and temperatures regularly stay in the low-to-mid 90s from June through August. When your home leaks air, that hot, sticky outdoor air pours in and your air conditioner has to work overtime to remove both the heat and the moisture. The city has a significant share of homes built before the 1980s - the craftsman bungalows near the University of North Alabama campus, the ranch homes in older subdivisions, the brick veneer houses closer to the Tennessee River. These homes were built at a time when nobody was thinking about air tightness, and that shows up in the energy bills their owners pay today. Florence is also served by the Tennessee Valley Authority through Florence Utilities, which has historically offered rebates for qualifying energy improvements. Programs change, so check before you schedule.
We serve the entire Shoals area, including homeowners in Sheffield and Tuscumbia, where the same older housing stock and humid climate create the same air sealing challenges we address in Florence every day. If you are tired of paying high cooling bills in a house that never feels quite comfortable, this is the place to start.
We ask about your home - age, whether it has a crawl space, and what has been bothering you. We reply within 1 business day. No cost to talk, no obligation to book.
A technician runs a pressurization test and identifies exactly where air is entering your home. This takes about an hour and gives you a real measurement - not a guess - of how leaky your home is.
You receive a written estimate listing every location being sealed, every material being used, and the total cost - including any TVA rebates or federal credits that may apply. No pressure to sign the same day.
The crew seals every identified gap using foam and caulk. Before leaving, they run the blower door test again and show you the before-and-after numbers. You keep that documentation for rebate applications.
Free estimate, no commitment. We reply within 1 business day.
(256) 367-9903We measure air leakage before we start and again when we finish - and we show you both numbers. That is the only honest way to verify the work made a difference. If a contractor cannot show you test results, you have no way to know what you paid for.
Most Florence-area homes sit on crawl spaces, and a crawl space that is not properly sealed is the biggest air leakage source in the region. We have worked in crawl spaces across Florence, Muscle Shoals, Sheffield, and Tuscumbia, and we know what to look for in each type of construction.
We check current TVA rebate availability as part of every estimate. Florence Utilities distributes TVA power locally, and qualifying projects can receive meaningful rebates - we help you understand what applies before you commit to anything.
A properly sealed home should have controlled fresh air - not just sealed gaps with no plan for ventilation. We follow ENERGY STAR guidelines for indoor air quality so your home breathes on purpose, not by accident.
Florence homes have specific air leakage patterns that come from their age, construction style, and the local climate. We work in this market every day, and that experience shapes how we find leaks and how we seal them.
