If your Ennis home feels hot, sticky, or expensive to cool no matter what you do, air leaks are likely the culprit. We find every gap and seal it so your AC works the way it should.
Air sealing in Ennis means finding and closing the gaps, cracks, and openings where outside air sneaks into your home and conditioned air leaks out, with most projects completed in a single day.
The biggest leaks in most homes are not around windows and doors - they hide in the attic floor, around recessed lights, where plumbing pipes pass through ceilings, and at the top and bottom of interior walls. In Ennis, where the air conditioner runs hard from late April through October, a leaky home is not just uncomfortable - it is expensive every single month of the cooling season.
Air sealing is most effective when paired with proper insulation. We often combine this service with basement insulation or attic air sealing to close off the full thermal envelope of the home in one visit.
If your electric bill has been creeping up year after year with no change in your habits, air leakage is one of the most common culprits. In Ennis, where summer cooling costs are already high, a leaky home can add hundreds of dollars to your annual utility bills compared to a well-sealed neighbor in a similar-sized house.
If one bedroom is always stuffy and hot in July while another room feels fine, that is a classic sign of air leakage and uneven pressure. Rooms above a garage, over a crawl space, or at the end of a duct run are the most common problem spots in Ennis homes built before modern air-tightness standards existed.
If your home feels sticky or clammy even with the air conditioner running, outside air is getting in faster than your system can remove the moisture. This is especially common in Ennis during July and August. Persistent indoor humidity is also a warning sign for mold growth in hidden areas of the home.
If your home sits on a pier-and-beam foundation and no one has ever inspected it with air sealing in mind, there is a strong chance it is a major source of energy loss and moisture intrusion. Crawl spaces in the Ennis area pull in hot, humid summer air through open vents and gaps that were standard construction practice for decades but are now understood to cause real problems.
We start every project with a diagnostic blower door test - a calibrated fan installed in one of your exterior doorways that drops the air pressure inside your home and forces outside air through every gap. This gives us an exact picture of where the leaks are before we seal a single thing. From there, the crew works through your attic, crawl space, and any identified problem areas, using foam and caulk to close gaps around pipes, wires, light fixtures, rim joists, and wall penetrations. Most of the work happens out of sight - in the attic and under the house - not in your living areas.
When air sealing is combined with attic air sealing or a full insulation upgrade, the results are meaningfully better than either service alone. We are also happy to discuss basement insulation at the same visit if your home has a conditioned basement or partial below-grade space that needs attention.
Best for any homeowner who wants to know exactly how leaky their home is before spending money on solutions - gives you real data, not guesswork.
Best for pier-and-beam homes and houses with open attics where the bulk of air leakage enters from above and below the living space.
Best for homes that consistently fail to hold a comfortable temperature - addresses leakage at every penetration point throughout the structure.
Ennis sits in Ellis County in North Central Texas, where summer temperatures regularly climb above 95 degrees and the air conditioner runs from late April through October. A leaky home is not just uncomfortable here - it is expensive for six or seven months straight. Many homes in Ennis were built in the 1960s through 1990s, before modern building codes required attention to air tightness. Homes of that era were built to let air move freely, and they typically have significant leakage around plumbing, electrical, and HVAC penetrations that add up to real money on every summer electric bill.
North Central Texas summers also bring high relative humidity, and when warm, moist outside air seeps into a cooled home, it can condense on surfaces inside walls and in the attic - quietly causing mold and wood rot in places you cannot easily see. Proper air sealing protects the structure of your home, not just your comfort. We work on homes throughout the area, including Cedar Hill and Glenn Heights, where the same housing conditions and humidity challenges apply.
Call or submit your details online and we will get back to you within one business day. We ask a few quick questions - home age, whether you have a crawl space, and what you have been noticing - so we arrive prepared.
On the first visit, we set up a calibrated fan in an exterior doorway and run the diagnostic test. This takes about an hour and shows us exactly where air is entering your home - and how much. You see the results before any sealing work is agreed to.
After the assessment, you receive a written estimate covering what will be sealed, where, and at what cost. There is no obligation at this stage. A good contractor answers your questions and lets you take time to decide.
Most Ennis homes are sealed in a single day. We run the blower door test again after the work so you can see the measurable improvement side by side with the before results. You receive documentation of what was done - useful for any federal tax credit claim.

(469) 881-8137We run a blower door test before starting so the scope of work is based on real data - not guesswork. The U.S. Department of Energy recommends this approach to ensure air sealing is targeted and verifiable. You see the numbers before and after - not just our word for it.
Many homes in the Ennis area are built on pier-and-beam foundations, and crawl spaces are often the largest single source of air leakage. We know what to look for in these spaces - rim joists, vents, pipe penetrations - and we seal them correctly for this climate, not just by the book.
A well-sealed home needs a controlled way to bring in fresh air. We check that your home has adequate ventilation after sealing - following standards set by ASHRAE - so you are not trading air leakage for a stuffy, poorly ventilated home. Air quality stays healthy.
Federal tax credits are currently available for qualifying air sealing and insulation work. We provide written documentation of what was done and where - so you have what you need to claim the credit when you file, without tracking anything down after the fact.
Every air sealing job we do ends with a before-and-after blower door test and written documentation of the work completed. You know exactly what was done, and you have the proof to back it up.
Target the attic floor - often the single largest source of air leakage in North Texas homes - for maximum impact.
