Your Longview home may be losing conditioned air through gaps you cannot see. Professional air sealing finds and closes those leaks - measured with a blower door test - so your cooling system stops fighting the outdoors all summer long.
Air sealing services in Longview, TX close the hidden gaps and cracks that let your cooled air escape and outdoor heat pour in - most residential jobs are completed in one day, with before-and-after measurements to confirm the improvement. Insulation slows heat transfer through surfaces, but air sealing stops uncontrolled air movement through gaps entirely. In a hot, humid climate like East Texas, both are necessary, and air sealing often delivers the more immediate comfort improvement.
The average older home in Longview leaks enough air that it is roughly equivalent to leaving a window open year-round. Those leaks are concentrated in the attic floor, around plumbing and wiring penetrations, and along the top plates of exterior walls. If your home was built before 1990 and has never had professional air sealing work done, it is almost certainly losing conditioned air every hour your system runs.
Air sealing pairs naturally with attic air sealing, which targets the single highest-leakage zone in most Longview homes - the gap-filled attic floor above your living space.
If your electric costs keep rising but your habits have not changed, air leakage is often the culprit. In Longview's climate, where air conditioners run hard from May through October, even moderate leakage can add hundreds of dollars to your annual energy bill. If your bill feels out of proportion to the size of your home, it is worth having someone measure how much air you are actually losing.
If one bedroom is always hotter than the rest of the house in July, or a back room never quite warms up in January, that is a classic sign of uneven air leakage. Gaps in the attic floor above that room, or around windows and outlets on exterior walls, allow outside air to bypass your HVAC system entirely. The thermostat cannot fix a problem that is happening in the walls and ceiling.
Hold your hand near an outlet on an outside-facing wall on a hot summer day. If you feel warm air coming through, that outlet is connected to the outside through gaps in the wall cavity. This is extremely common in Longview homes built before the 1990s, and it is one of the easiest problems for a contractor to identify and fix.
The same gaps that let your cooled air out also let East Texas bugs in - gnats, roaches, and other insects that thrive in the warm, humid conditions around Longview. If you are finding insects in rooms that seem sealed, or if dust accumulates quickly after cleaning, outside air is finding its way in through gaps you cannot see. Air sealing closes those pathways throughout the attic and walls.
We start every air sealing job with a blower door test - a large fan mounted in your doorway that pressurizes the house and shows us exactly where the leaks are. This is not guesswork. We get a measured leakage reading before we begin, and we run the test again after the work is done so you have documented proof of improvement. Sealing work uses spray foam for gaps around pipes and wiring, caulk for smaller cracks along framing and trim, and weatherstripping for doors and attic hatches. Our targeted attic air sealing service addresses the attic floor independently for homeowners who want to focus on that zone first.
Many Longview homeowners combine air sealing with a full insulation upgrade in the same visit, since both improve together far more than either one alone. If your basement insulation or rim joists are also lacking, we can address those areas during the same project to save on labor and scheduling time.
Best for homes with high utility bills and consistent temperature complaints throughout.
Suited for homes where the attic floor has never been sealed and the attic is the primary leakage zone.
Ideal for homeowners who want a measured baseline before deciding what work to prioritize.
Best value for homes where both leakage and thin insulation are contributing to high bills.
Longview's combination of long, brutally hot summers and high year-round humidity makes air leakage more expensive here than in a milder climate. Your air conditioner runs hard from May through October - and every gap in your home's envelope lets expensive cooled air escape while pulling in humid, 95-degree outdoor air. The result is not just higher bills. Warm, moist outside air entering through gaps in the attic and walls can condense inside your home, contributing to moisture problems and reducing the lifespan of your insulation and framing. A contractor working in this climate needs to think about both air and moisture management together.
Many of Longview's established neighborhoods - including areas with homes dating from the 1950s through the 1980s - have never had professional air sealing work done. We serve homeowners throughout Lufkin and Nacogdoches, where the same East Texas climate and older housing stock create identical leakage problems. Fall and early spring are the best times to schedule in this region - attic temperatures drop to a manageable range, and you are ready before the next extreme season arrives.
Air sealing and insulation improvements may also qualify for the federal Energy Efficient Home Improvement Credit, covering up to 30 percent of qualifying project costs, up to $1,200 per year.
We respond within 1 business day. We will ask your home's age, approximate square footage, and what is prompting your concern - high bills, drafty rooms, or both. No cost or commitment to ask questions.
We set up a large fan in your front doorway and measure exactly how leaky your home is right now. This takes about an hour and tells us - and you - where the biggest problems are hiding before we do any sealing work.
After the test, we walk you through what we found and provide a written estimate. You are not obligated to proceed the same day. Take time to compare if you are getting multiple quotes.
The crew works through the attic floor and other identified areas, sealing gaps with foam and caulk. After the work, we run the blower door test again so you have before-and-after numbers proving the improvement.
We measure first, then quote - so you know exactly what you are paying for and what the result will be. No guesswork, no obligation.
(430) 267-1839We measure your home's air leakage rate before and after every air sealing job. You get documented before-and-after numbers - not a contractor's word that things improved. That measurement is also the documentation you need to apply for the federal energy efficiency tax credit.
We work in Longview and across 11 surrounding communities, from Tyler to Marshall to Nacogdoches. That regional reach means we know the East Texas housing stock, the local climate conditions, and the specific leakage patterns common in homes built here between the 1950s and 1980s.
Air sealing in a humid climate like East Texas is not the same as air sealing in a dry one. We assess whether your home needs ventilation adjustments alongside sealing, so you do not end up with a tightly sealed house that traps humidity and indoor air quality problems.
Building Performance Institute standards guide how we measure, diagnose, and document home performance improvements. This means the work follows a nationally recognized framework - not informal methods. It is also the standard that qualifies the work for federal tax credit documentation.
Air sealing is the kind of work where the quality of the contractor matters as much as the materials used. Measured results, documented improvements, and a contractor who understands your climate are what separate a job that pays off from one that just checks a box.
