High summer bills and a home that never quite cools down are often caused by hidden gaps letting hot outside air pour in. Air sealing closes those gaps for good.
Air sealing services in Pineville means finding and plugging every gap, crack, and opening in your home's shell - around pipes, wires, light fixtures, attic hatches, and wall joints - so that hot outside air cannot sneak in and your conditioned air cannot leak out. Most jobs take one to two days, and your home is comfortable and ready to use immediately after.
Air sealing is not the same as adding insulation - though the two work together. Think of it as patching every hole in a bucket before you try to fill it. In Pineville's climate, where outdoor air sits at 95 degrees and high humidity for months at a time, even small gaps in your home's shell force your air conditioner to run nearly nonstop. Older homes - a large share of Pineville's housing stock was built before the 1980s - were simply not built with air tightness in mind, and decades of settling create dozens of small openings that add up fast. For the most complete energy upgrade, pairing air sealing with basement insulation or attic air sealing delivers even stronger results.
Air sealing also reduces how much outdoor humidity, dust, and allergens enter your home - which matters a lot in central Louisiana where outdoor air quality and pollen counts are high for much of the year.
If your Cleco bill climbs dramatically from May through September and your usage habits have not changed, air leaks are one of the most common culprits. In Pineville's climate, an unsealed home forces your air conditioner to run almost constantly. If neighbors in similar-sized homes are paying noticeably less, that is a strong signal your home needs attention.
Hold your hand near an electrical outlet on an exterior wall on a hot summer day. If you feel warm air or the outlet plate is warm to the touch, outside air is moving through the wall cavity into your home. The same test works near recessed lights - if the area around a fixture feels warm, there is a gap above it leading to the attic.
If your home feels muggy even with the air conditioning on, humid outside air is likely finding its way in faster than your system can remove it. This is especially common in older Pineville homes with pier-and-beam foundations, where the crawl space below acts like a humidity pump directly into your living space.
Dark streaks or rings around recessed lights, ceiling fans, or the edges of your attic access hatch are a visible sign that air has been moving through those openings for a long time, carrying dust with it. If you see this, there are likely other nearby leaks that are not as obvious.
We perform whole-home air sealing for residential properties throughout Pineville and central Louisiana. Our process starts with a blower door test - a large fan temporarily mounted in your front doorway that depressurizes the house so leaks become easy to find. We use foam, caulk, and weatherstripping to close every penetration: every pipe, wire, duct, and light fixture that passes through a wall or ceiling. We also address attic air sealing specifically, which is where the majority of leakage occurs in Louisiana homes.
For homes with crawl spaces - common throughout Pineville and Rapides Parish - we seal the floor above the crawl space or offer full crawl space encapsulation to stop hot humid air from entering from below. After all sealing work is complete, we run a second blower door test to confirm the leakage rate actually dropped. That follow-up test is the difference between a documented result and a guess. We also check that your home still has adequate ventilation so that tight air sealing does not create indoor air quality issues - pairing the work with basement insulation is common for homes where the lower level is also a significant source of heat gain.
Best for homeowners who want to address every air leak in one project and get a measurable, documented result.
Focused on the attic floor - where most heat and air exchange happens - ideal as a standalone upgrade or part of an attic insulation project.
For pier-and-beam homes where the crawl space is driving humidity and heat into the living space from below.
We confirm the leakage rate dropped with a second test after the work - documentation you can use for tax credits and utility rebates.
Pineville sits in Rapides Parish in central Louisiana, where summer temperatures regularly climb into the mid-90s and outdoor humidity stays high for months at a time. That combination means your air conditioner is working harder than it would almost anywhere else in the country. Air sealing directly reduces how hard your AC has to work, and the savings show up fast - often within the first full summer after the work is done. Humidity is also a structural concern: uncontrolled air leaks are one of the main ways moisture gets into walls and attics, where it can quietly cause mold and wood rot over years.
Homes in Pineville and nearby Natchitoches share the same challenge - older housing stock built well before air tightness was a priority, combined with decades of renovation work that created new penetrations nobody ever sealed. If your home has had any significant work done over the years - new electrical, recessed lighting, bathroom additions - those penetrations are very likely still open and worth addressing.
We ask a few quick questions about your home's size, age, and what has been bothering you - high bills, humidity, drafts. You will hear back within one business day to schedule an assessment.
We mount a large fan in your doorway, depressurize the house, and use a smoke pencil or thermal camera to pinpoint exactly where air is entering. The test takes about an hour and gives us the data to write an accurate quote.
The crew works primarily in your attic, crawl space, and utility areas - not your living rooms. Most Pineville homes are completed in one full day. You can stay home the entire time.
After sealing, we run the blower door test a second time to confirm the leakage rate dropped. You receive both test results in writing - documentation you can use for federal tax credits or Cleco rebates.

(318) 319-2726We run a blower door test before and after every air sealing project. That means you leave with a number - not a promise - showing exactly how much the leakage rate dropped. Most contractors skip the follow-up test. We do not.
Pier-and-beam homes are common throughout Pineville and surrounding Rapides Parish. We know how to seal the floor above a crawl space and how to assess whether full encapsulation is needed. This is one of the highest-impact fixes in a Louisiana home.
We hold a valid Louisiana state contractor license. Every job we take is in central Louisiana - we know the climate, the housing stock, and the specific challenges that Pineville homes present. lslbc.louisiana.gov
Tightly sealing a home can affect ventilation if done carelessly. We check that your home still has adequate fresh air after the work is done - so you get a tighter, more efficient home without trading efficiency for air quality.
Every air sealing project we complete is backed by test data and documentation. You will know the work made a measurable difference - and you will have the paperwork to prove it at tax time.
