Hidden gaps let cold air in and warm air out all winter long. We find every leak with diagnostic testing and seal them before Austin temperatures hit zero.
Air sealing services in Austin, MN find and close the hidden gaps where outside air sneaks in and conditioned air leaks out, most homes are completed in one to two days using foam, caulk, and diagnostic testing to confirm real improvement.
Most air leaks are not where you expect them. The biggest culprits are usually in the attic - around light fixtures, plumbing pipes, and the top of interior walls - not around windows and doors. In older Austin homes, these gaps have never been sealed and decades of Minnesota freeze-thaw cycles have widened them further.
Air sealing works best when paired with basement insulation to address heat loss from below as well as above. If you also have ice dams or an attic that overheats in summer, our attic air sealing service targets the specific problem of warm air escaping into the roof cavity.
If your gas or electric bill spikes sharply every November and stays high through March, your home is likely working harder than it should to stay warm. Austin winters are long and cold, and a leaky home can cost hundreds of dollars more per year than a sealed one of the same size.
Stand in your living room on a cold January day and pay attention to your ankles. If you feel a chill near the floor, or if the ceiling of an upstairs room feels noticeably colder, air is moving through gaps you cannot see. These drafts are especially common in older Austin homes where the top of interior walls connects to an unsealed attic space.
If one bedroom is always colder than the rest of the house in winter, or one room feels stuffy in summer no matter what you do with the thermostat, uneven air sealing is often the cause. Air leaks disrupt the way your heating and cooling system distributes air, creating hot and cold spots that are frustrating to live with.
Ice dams form when warm air escapes into your attic, heats the underside of the roof, and melts snow from below. That meltwater refreezes at the cold eave. If you had ice dams last winter, warm air is very likely escaping through gaps in your ceiling that an air sealing contractor can find and close.
We start with a blower door test - a diagnostic tool that pulls air out of your home and reveals exactly where leaks are hiding. Most homeowners are surprised by the results. The biggest losses are almost always in the attic, around plumbing and wiring penetrations, and along the rim joist in the basement. Once we know where air is moving, we seal those spots with foam and caulk in the right sequence. For homes dealing with ice dams or poor attic performance, our dedicated attic air sealing service addresses those specific locations in detail.
For homeowners who want a complete picture of their home's energy performance, we can combine air sealing with basement insulation in a single project. A sealed basement rim joist and properly insulated basement walls make a noticeable difference in the comfort of the floors above. We also run a second blower door test after the work is complete so you have a real before-and-after number, not just a contractor's word.
Best for homes with high energy bills and multiple drafty areas - covers attic, basement, and all major penetrations.
Focused service for homes with ice dams or attic heat gain issues, targeting the top-plate and ceiling penetrations.
Ideal for homes with cold floors and drafts near the foundation - one of the most cost-effective air sealing locations.
Austin's winters are genuinely hard on homes. Temperatures regularly drop below zero, and Mower County's flat, open farmland means wind moves across the area with little to slow it down. Every freeze-thaw cycle through late fall, winter, and early spring widens existing gaps slightly - and Austin homes have been through hundreds of these cycles. A home that was built in the 1960s and never air sealed has had decades of Minnesota weather working to open up its cracks. Homeowners in Winona face the same cold-climate conditions and rely on the same diagnostic-first approach we bring to every Austin job.
Austin's summers bring a second problem. Warm, humid air pushes in through the same gaps that let cold air in during winter. When that moisture-laden air meets cooler surfaces inside your home, it can deposit moisture inside walls or the attic - leading to mold or wood rot over time. Sealing those gaps protects your home in both directions. Homeowners throughout Mankato and the broader southeastern Minnesota region deal with both extremes of this climate and benefit from the same whole-home sealing work we do in Austin.
We ask a few basic questions - the age of your home, any energy work done before, and what problems you have noticed. No technical knowledge needed. Expect a reply within one business day.
We walk through your attic, basement, and crawl space and run a blower door test to measure exactly how leaky your home is. This visit takes one to two hours and gives us the information we need to quote accurately.
After the assessment, we provide a written quote explaining what work we recommend, where the biggest leaks are, and the total cost. We walk you through available utility rebates and tax credits at this stage.
Most homes are sealed in one day. We run a second blower door test after the work is done and show you the before-and-after numbers. You leave with proof of improvement, not just a receipt.
We test before and after - so you see real improvement, not just a promise.
(507) 509-6204A blower door test runs before any foam is applied. That tells us exactly where air is moving and in what volume - so we seal the right spots in the right order, not just the obvious ones.
We run a second blower door test after the work is complete. You see the exact improvement in your home's airtightness. A contractor who skips this step is guessing, not confirming.
We work regularly throughout Mower County and the surrounding area, which means we know the housing stock, the climate, and the specific challenges that come with older homes in this part of Minnesota.
A well-sealed home needs proper ventilation to stay healthy. Before finishing, we confirm that your bathroom fans, kitchen exhaust, and combustion appliances are venting correctly. This step is not optional - it protects your family's air quality. See ASHRAE standards at .ashrae.org
Diagnostic testing, honest pricing, and confirmed results - those are the things that set a real air sealing job apart from a can of foam and a handshake.
