Sherman summers push attic temps above 150 degrees. Every gap in your ceiling is a pipeline for that heat into your living space - and a reason your AC runs all day without catching up.
Attic air sealing in Sherman, TX means a contractor finds every gap, crack, and opening where your home's conditioned air leaks into the attic - then plugs those holes with foam or caulk - most jobs in a single-story Sherman home take four to eight hours and require no disruption to your living space.
If your cooling bills spike every summer even when the thermostat stays the same, or if certain rooms never quite cool down the way the rest of your home does, air leaks are almost certainly part of the reason. Those leaks are often invisible - gaps around recessed light fixtures, the spaces where plumbing and electrical pass through your ceiling, and the joint where interior walls meet the attic floor. None of them look like much on their own, but together they add up to a serious drain on your comfort and your wallet. For homes where insulation is also thin or settled, air sealing services and insulation upgrades are often done in the same visit to maximize the return.
The U.S. Department of Energy estimates that air leaks account for a substantial share of energy used for heating and cooling in a typical home. The U.S. Department of Energy publishes guidance on air sealing techniques and expected results for homeowners who want to understand the process before scheduling work.
If your cooling costs jump dramatically from May through September without any change in how you use your home, air leaks are a likely culprit. In Sherman's climate, an unsealed attic acts like a heat pump running in reverse - constantly pushing hot air into your living space and forcing your air conditioner to run longer than it should to compensate.
If one bedroom or the back of your house always runs a few degrees warmer than the rest of your home, conditioned air is likely escaping near that area before it can do its job. Uneven temperatures from room to room are one of the most common complaints before air sealing and one of the first improvements homeowners notice afterward.
Older homes in Sherman's established neighborhoods were built to the standards of their era, which were far less airtight than what is required today. If you have lived in your home for years and can't recall anyone doing insulation or sealing work, there is a strong chance your attic has gaps that have been there since the house was built.
Hold your hand near a recessed light fixture in your ceiling on a hot summer day. If you feel warm air coming through, that is attic air pushing into your home through an unsealed gap. The same test applies around ceiling fans, attic access hatches, and the tops of interior walls - all common leak points in homes that have never been sealed.
Our crew works methodically across your attic floor, applying foam or caulk to every gap - around recessed lights, pipe and wire penetrations, the tops of interior walls, and the attic hatch itself. We do not spot-seal the obvious areas and move on. We cover the full ceiling plane so there are no leaks left behind to undo the work already done. For homes that also need insulation, we offer full retrofit insulation work in the same visit, which lets both improvements work together rather than fighting against each other.
We also offer blower door testing before and after the work, which gives you a measurable number - not just a promise - showing how much air leakage your home had before we started and how much it has after. This is the most honest way we know to demonstrate that the work was done thoroughly. Contractors who skip this step are asking you to trust them on faith. We think you deserve actual data. For homes where the whole building envelope needs attention, our broader air sealing services page covers the full scope of what we do beyond the attic.
Suits most Sherman homes - systematic sealing of every penetration in the attic floor using foam and caulk, typically completed in one day.
For homeowners who want before-and-after proof of reduced air leakage - not just a verbal assurance that the work was done well.
Ideal for homes where sealing and adding insulation are both needed - done in one visit so the improvements compound each other.
For homeowners not sure whether air sealing or insulation is the right first step - we assess and explain what we find before recommending work.
Sherman sits in North Texas where summer temperatures routinely climb above 100 degrees and the heat index pushes even higher. That kind of sustained heat means your attic can reach extreme temperatures on a July afternoon, and every gap in your ceiling is a direct pipeline for that heat into your living space. Grayson County also gets cold winters - temperatures occasionally drop below 20 degrees - which means an unsealed attic costs you money in both directions. Homes in Sherman that haven't been air sealed are losing conditioned air in summer and heated air in winter, every single day. A significant portion of Sherman's residential neighborhoods were built before modern energy codes required tight construction, and many have never had any sealing work done at all. Homeowners in Denison, TX and Gunter, TX deal with the same climate conditions and call us for the same reason.
Oncor Electric Delivery serves the Sherman area and has historically offered rebate programs for energy efficiency improvements. It is worth checking their current offerings before scheduling work - even a modest rebate can meaningfully reduce your out-of-pocket cost. North Texas wind also plays a role: when outside air is moving, it pushes through gaps in your home's envelope more aggressively, which is why some homeowners notice the problem most on windy spring and fall days. Air sealing addresses that infiltration directly, regardless of the season or the wind speed. For an authoritative resource on air sealing methods and expected results, the ENERGY STAR program publishes guidance homeowners can review before and after the work is done.
We will ask a few basic questions - your home's age, square footage, and whether any energy work has been done before. We respond within one business day and can typically schedule an initial visit within a few days of your call.
A technician walks through your home, goes into the attic, and may run a blower door test to measure how much air is leaking and where it is coming from. This takes one to two hours and gives us what we need to quote the job accurately.
The crew works systematically across your attic floor applying foam and caulk to every gap they find. Most single-story Sherman homes are done in four to eight hours. Your living space is undisturbed - no strong odors, no mess inside.
When the work is done, we walk you through what was sealed. If blower door testing was included, we show you the before-and-after numbers. We also provide documentation you will need for any rebate or tax credit claim.
Free assessment. Written estimate. No pressure to book on the day.
(903) 294-5640We use blower door testing before and after every job so you get an actual number showing how much air leakage improved - not just a contractor's word that the work was done well. That kind of proof is rare in this industry and matters when you are trusting someone with your home.
We have been sealing attics in Grayson County since 2015 and know the housing stock here - the older ranch homes near downtown, the brick homes built in the 1970s and 1980s, and the newer subdivisions going up on the north side of town. That local knowledge shapes how we approach each job.
We seal every penetration in the attic floor - not just the obvious ones a quick crew would address. Recessed lights, pipe and wire chases, interior wall top plates, and the attic hatch all get sealed. Skipping any of these leaves significant leaks that undo the work already done.
We provide the documentation you need to claim federal energy efficiency tax credits and any available Oncor rebates. The Building Performance Institute recommends that contractors following best practices support homeowners through this process - and we do.
Every credential and practice we follow comes back to the same thing: you should know exactly what was done in your attic and be able to verify it. We work that way because it is the right way to do business, and because Sherman homeowners deserve a contractor they can hold accountable.
Add insulation to your existing attic or walls without tearing anything out - ideal when sealing alone is not enough to hit comfort goals.
