Hidden gaps in your attic, crawl space, and walls let Florence's summer heat pour in and cool air pour out. We find every leak with a blower door test and close them for good.

Air sealing services in Florence, SC locate and close the hidden gaps where outside air enters and conditioned air escapes - most residential jobs are completed in one to two days and always begin with a blower door test to measure exactly how leaky your home is before any work starts. Closing those gaps takes direct pressure off your air conditioner and makes every room more comfortable.
The biggest leaks in a Florence home are rarely around windows and doors. They are in the attic floor where wires and pipes pass through, along the crawl space rim, and inside wall cavities at every electrical outlet on an exterior wall. Many homes in Florence were built in the 1960s through 1980s before builders paid much attention to air tightness, and those homes often lose a significant amount of conditioned air every hour. When those leaks are paired with a home that also needs basement insulation or attic upgrades, addressing air sealing first gives every other improvement a better foundation to build on.
If your cooling costs feel high relative to how you set your thermostat, air leakage is one of the most common culprits. Florence's long, humid summers mean your AC runs hard for months, and every gap in your home's envelope makes it work harder than it should. Bills that have been creeping up year after year without a clear explanation are a reliable reason to have a leakage test done.
If one bedroom stays stuffy in July no matter what you do, or a back hallway feels noticeably warmer than the living room, that unevenness often points to air leaks nearby. Hot outside air is finding a way in and your AC cannot keep up in that specific spot. This is one of the most common complaints Florence homeowners describe before air sealing work is done.
Florence's summer humidity is intense, and when humid outside air leaks into your home through gaps in the crawl space or attic floor, it brings that moisture with it. A persistent musty smell - especially in lower-level rooms or near the floor - often means humid air from below is entering the living space. Air sealing the crawl space boundary addresses this at the source.
Hold your hand near an electrical outlet on an exterior wall on a hot day and see if you feel air moving. If you do, that is outside air coming through the wall cavity. This is a very common finding in Florence homes built in the 1970s and 1980s, and it is exactly the kind of leak that air sealing is designed to close permanently.
Every job starts with a blower door test - a fan mounted in the front door that depressurizes the house and measures exactly how much air your home leaks. This gives us a real number to work from and lets us locate the biggest sources before we touch anything. We then work systematically through the highest-impact areas: the attic floor around every penetration, the crawl space rim and floor joist boundary, and the wall cavities behind outlets and switches on exterior walls. We use foam, caulk, and weatherstripping matched to the location and size of each gap - not a single product sprayed everywhere. For homes that also need attic air sealing as a focused project, we can scope that separately or as part of a whole-home effort.
Once sealing is complete, we run the blower door test a second time. You receive both numbers in writing - a before and an after - so you have a documented record of the improvement. A contractor who skips the follow-up test is guessing, not solving. The Building Performance Institute sets standards for this kind of diagnostic-driven work - including the requirement that ventilation be checked after tightening a home so indoor air quality is not compromised in the process. We also let you know about any available federal tax credits or utility rebates - Santee Cooper and Duke Energy Progress both serve Florence-area homes and have offered energy efficiency programs worth asking about. For homes where air sealing is one piece of a larger project, we coordinate it alongside basement insulation and other thermal upgrades so everything works together.
Pre- and post-work measurement of your home's air leakage rate - gives you a real before-and-after number, not an estimate.
Sealing every penetration in the attic floor - the highest-impact zone in most Florence homes for both cooling season and winter heating.
Closing the gaps where humid ground air enters your living space from below - especially important in Florence's high-humidity climate.
Systematic sealing across attic, crawl space, and wall penetrations for homes that need comprehensive improvement across all zones.
Florence sits in the Pee Dee region of South Carolina, where summer temperatures regularly climb into the low 90s and humidity stays high from May through September. When outside air leaks into a home that is trying to stay cool, the air conditioner has to work much harder - and your electric bill reflects that every month. The payback on air sealing in Florence tends to be faster than in milder climates simply because the cooling season is so long. Most homes in Florence are also built on crawl space foundations, and crawl spaces in this region are exposed to warm, humid ground air year-round. Sealing the boundary between the crawl space and the living area is often the single highest-impact step a Florence homeowner can take - before spending anything on new equipment or upgrading insulation. The U.S. Department of Energy consistently identifies attic and crawl space air sealing as among the highest-return energy improvements available to homeowners in hot and mixed-humid climates.
Florence's housing stock adds to the opportunity. A large share of homes in the area were built in the 1960s through 1980s before builders paid much attention to air tightness - and those homes have been leaking conditioned air ever since. Contractors serving homes across Darlington, SC and Sumter, SC see the same pattern in the older housing stock throughout the Pee Dee region - homes that were never sealed and have significant leakage that has never been measured or addressed. Florence winters are mild but not without cost - temperatures drop into the 30s regularly from December through February, and homes that leak air lose heat quickly on those cold nights, forcing heating systems to run longer than they should.
Call or submit your information through the estimate form and we respond within one business day. We ask a few quick questions upfront - the age of your home, whether you have a crawl space, and what symptoms you have been noticing - so we arrive prepared.
We set up a fan in your front doorway, depressurize the house, and measure exactly how leaky your home is. This takes about an hour and gives us a specific number - not a guess - for where you stand before any work begins.
We work through the attic floor, crawl space boundary, and wall penetrations systematically, using the right material for each type of gap. You can stay home during the work - we keep the job area contained and clean as we go.
Once sealing is complete, we run the blower door test a second time and give you both numbers in writing. You will know exactly what improved and by how much - a documented record you can keep for your files or reference when comparing utility bills.
We test before and after every job. Written quote upfront. No guesswork - you get real numbers showing the improvement.
(854) 204-1707We measure leakage before the work starts and again when it is done. You get both numbers in writing so you know exactly what improved - not a contractor's word for it. A job without a follow-up test is a guess, not a solution.
South Carolina requires insulation and air sealing contractors to hold a valid state license. Ours is current and verifiable through the SC Contractors Licensing Board. You can look it up yourself before signing anything - we expect you to.
Most Florence homes sit on crawl space foundations, and crawl spaces here are one of the most significant sources of air leakage in the region. We treat the crawl space boundary as a primary focus - not an afterthought - and account for Florence's persistent ground moisture in every recommendation we make.
Sealing a home tightly without checking ventilation is how indoor air quality problems start. After every job, we confirm your home still has adequate fresh air exchange - or let you know if a simple adjustment is needed. This step is often skipped; we do not skip it.
Every air sealing job we complete is documented with real before- and-after measurements, carried out by a licensed contractor who knows Florence's housing stock and the specific demands of the Pee Dee climate. You get a straight answer about what your home actually needs - and proof that the work made a difference.
