Serving Alexandria, LA and surrounding areas. (318) 206-4010
Invisible gaps in your attic, crawl space, and walls let conditioned air out and Louisiana humidity in. We find and close them - with before-and-after testing to prove the difference.
Air sealing services in Alexandria, LA find and close the small gaps, cracks, and penetrations in your home where outside air sneaks in and conditioned air leaks out - most jobs take a few hours to a full day and start reducing your energy costs within the first billing cycle after the work is done. These gaps are usually invisible: hidden in attic floors, around pipes, behind electrical outlets, and where walls meet ceilings.
In central Louisiana, where your air conditioner runs hard from spring through fall, a leaky home does not just cost more to cool - it also lets in humid outdoor air that your system has to wring out. That humidity strain adds up. Alexandria homes built before the 1980s were not built with air tightness in mind, and decades of settling and pest activity have added new gaps since. Adding air sealing alongside basement insulation or attic work closes the full picture instead of just part of it.
Many Alexandria homes also sit on pier-and-beam foundations with open crawl spaces underneath - one of the biggest air leak pathways in the region. If your home has a crawl space, that is almost always the first place we look.
If your Entergy bill spikes every summer even though your air conditioner is relatively new and your habits have not changed, air leakage is a likely culprit. In Alexandria's climate, an unsealed home forces your system to run almost constantly to fight the heat and humidity pouring through gaps.
If one bedroom is always warm and stuffy even with the vents fully open, or a room near the attic hatch feels noticeably hotter than the rest of the house, conditioned air is escaping and hot attic air is finding its way in. This is especially common in older Alexandria homes where the attic floor has never been sealed.
Alexandria's humidity is relentless. When warm outdoor air leaks into a cooled space, it condenses on cool surfaces and creates the conditions for mold and mildew. If you smell mustiness in closets, see condensation on interior walls, or notice paint bubbling near baseboards, humid air infiltration is likely the cause.
Many Alexandria homes on pier-and-beam foundations allow ground moisture and air to rise through the floor from below. If you notice a damp or earthy smell in your living areas - especially in the morning or after rain - air is likely moving up from an unsealed crawl space.
We seal gaps in attic floors, crawl space rims, around plumbing and wiring penetrations, behind knee walls, and at the spaces where walls meet ceilings. These are the locations where the most air movement happens in a typical Alexandria home - and where the most conditioned air is lost. We use foam and caulk depending on the gap size and location. For homes where the crawl space is the main culprit, we work from below to close off the rim joist area and any penetrations that pass through the floor.
Air sealing works best when combined with insulation. Sealing alone stops air movement; insulation then slows heat transfer through the same surfaces. We pair air sealing with our attic air sealing service for homeowners who want to address the attic specifically, or with full insulation work for those doing a more comprehensive upgrade. The U.S. Department of Energy estimates that air sealing and insulating together can cut heating and cooling costs by up to 15 percent.
Best for homes where conditioned air is escaping up through the ceiling into an unconditioned attic.
Addresses the gap where the floor meets the foundation - a major air pathway in pier-and-beam Alexandria homes.
Closes gaps around pipes, wires, recessed lights, and HVAC ducts that pass through ceilings and floors.
Measures your home before and after sealing so you have actual proof the work reduced air leakage.
Air sealing matters more in a humid climate like Alexandria's than in most of the country because it is not just heat you are keeping out - it is moisture. When warm, humid outdoor air leaks into a cooled home, it deposits moisture on cool surfaces, which creates the conditions for mold and mildew inside walls and in attic framing. The older neighborhoods of Alexandria - including areas built near downtown and around the Garden District - have homes that were never designed to be airtight, and they have had decades to develop new gaps from settling, pest damage, and renovation work.
Entergy Louisiana, which serves most of Alexandria, has offered rebate programs for energy improvements including air sealing - worth checking before you schedule work since programs change. We serve Alexandria and neighboring communities including Pineville and Marksville, and we know the housing types and conditions in each of these areas. For income-qualifying households, Louisiana also participates in the federal Weatherization Assistance Program, which can cover air sealing and insulation at no cost.
When you reach out, we ask about the age of your home, whether you have a crawl space or attic, and what problems you have noticed. We respond within 1 business day and show up prepared - not starting from scratch on arrival.
We walk through your home and access the attic and crawl space. Many jobs start with a blower door test - a temporary fan that measures how much air your home is leaking - so you have a real number to compare against after the work is done.
After the assessment you get a written estimate explaining what areas will be sealed, what materials will be used, and the total cost. We also tell you whether your project qualifies for Entergy Louisiana rebates or the federal energy efficiency tax credit.
The crew applies foam and caulk to the attic floor, crawl space rim, and penetrations. Most of the work is out of sight. We run a final measurement when done and provide documentation for any rebate or tax credit claim.
