Unsealed gaps in your attic floor let heated air escape all winter - sealing them is the fix that makes insulation actually work and ends ice dams for good.
Attic air sealing in Eau Claire means finding and plugging the gaps in your attic floor that let heated air escape from your living space - most jobs are completed in a single visit, in two to five hours, with no need to leave your home. The gaps are not visible from below: they are around light fixtures, plumbing pipes, and the tops of interior walls - and they have been leaking heat through your ceiling every winter.
Insulation slows heat from moving through solid surfaces, but it cannot stop air from flowing through openings. That is why adding more blown-in insulation on top of an unsealed attic floor delivers only partial results. Sealing the gaps first means the insulation you already have - and any new insulation you add - actually does its job. Many homeowners in Eau Claire pair this service with air sealing services for the walls and basement to address the full building envelope.
If your home was built before 1980, there is a strong chance your attic has never been properly sealed. That means decades of heat loss through the same gaps, year after year. The fix is straightforward and usually pays for itself in energy savings within a few heating seasons.
If your gas or electric bills seem out of proportion to the size of your home - especially during Eau Claire's long heating season - air leaks in the attic are a likely culprit. Heat rises, and if your attic floor is full of gaps, that heat is going straight through your ceiling and out into the cold. This is one of the most overlooked reasons Eau Claire homeowners overpay for heat every winter.
When certain bedrooms or areas of your home feel drafty or harder to keep warm, it often points to air leaking out through the ceiling above. This is especially common in older Eau Claire homes where attic insulation was installed without any air sealing underneath. The fix is usually straightforward once a contractor gets up there and finds the gaps.
If you have ever peeked into your attic on a cold day and noticed frost on the roof boards or wet spots on the framing, warm humid air from your living space is escaping upward and condensing when it hits the cold attic. Eau Claire winters make this problem more visible than in warmer climates. Left unaddressed, it can lead to mold and structural damage over time.
Ice dams form when heat escaping through your attic melts snow on the roof, which then refreezes at the cold eaves. They are a recurring problem for many Eau Claire homeowners because of the city's freeze-thaw cycles. Sealing the air pathways in your attic floor is one of the most effective steps you can take to stop them from forming in the first place.
We work through your attic floor systematically, sealing every penetration - pipes, wires, chimneys, light fixtures, and the tops of interior walls - using foam and caulk rated for this application. Before we start, we check for bathroom fans and kitchen vents that may be discharging into the attic rather than outside, because trapping humid air in a sealed attic creates its own moisture problems. We can also apply a blower door test before and after the job so you have a measurable result, not just our word that the work was done. We connect this work with full crawl space vapor barrier and other envelope improvements when the project calls for it.
For homes where insulation also needs upgrading, we coordinate the air sealing and insulation in a single visit so you are not paying for two mobilizations. Qualifying projects may be eligible for Wisconsin Focus on Energy rebates - we handle the paperwork on your behalf so you capture the rebate without the hassle. We also pair attic sealing with full air sealing services for homeowners who want to address the entire building envelope at once.
For any Eau Claire home where gaps around pipes, wires, and fixtures have been leaking heat for years without being addressed.
Measures air leakage before and after the work - gives you a number that proves the improvement, not just a contractor's assurance.
Confirms bathroom fans and kitchen vents exit the house properly before sealing begins - prevents moisture problems after the job.
Ideal for older homes where sealing and adding insulation in the same visit delivers the biggest energy improvement per dollar spent.
Eau Claire averages around 50 inches of snow per year and sees temperatures drop well below zero on the coldest nights. That means your furnace runs hard for five or more months, and every gap in your attic floor is a direct path for that expensive heat to escape. Homeowners here feel the impact of air leaks more sharply than people in milder climates - which is why attic air sealing delivers a faster return on investment in this region than almost anywhere else. A large share of Eau Claire homes were built in the 1940s through the 1970s, a period when attic air sealing was not standard practice. If your home was built before 1980, there is a good chance your attic has never been properly sealed - meaning dozens of gaps that have been quietly costing you money every winter since the house was built.
Eau Claire's repeated freeze-thaw cycles - common from November through March - also create specific attic moisture risks. When warm humid air escapes through ceiling gaps into a cold attic, it condenses on roof sheathing and framing, creating conditions where mold and wood rot can develop over time. Sealing those air pathways protects your attic structure, not just your heating bill. We serve homeowners throughout the region, including in Rice Lake and Chippewa Falls, where the same climate conditions apply.
We get back to you within one business day. We ask a few quick questions - your address, the age of your home, and whether you have had any insulation work done before. You do not need to prepare anything for this first conversation.
We inspect the attic, note current insulation levels, identify visible gaps, and check for any moisture or ventilation issues. Many contractors use a blower door test at this stage to measure how much air is leaking. You get a written estimate - no obligation, no pressure to commit.
We walk you through what we found and what we recommend. This is the right time to ask about Focus on Energy rebates and whether a permit is needed for your project. We will answer those questions directly before you sign anything.
The crew works through the attic, sealing every gap with foam and caulk. Most homes are done in two to five hours and you can stay home the entire time. When finished, we run the blower door test again to confirm the improvement, and you are fully back to normal the moment we leave.
Most jobs are done in a single visit and you can stay home the whole time. Free estimate, no obligation - we will tell you exactly what we find and what it will cost.
(534) 400-0045We are familiar with Wisconsin's Focus on Energy program and handle the rebate paperwork on behalf of qualifying customers. That means you capture the available savings without navigating the submission process yourself. Many Eau Claire homeowners are surprised how much a rebate reduces the out-of-pocket cost on a project like this.
We can run a blower door test before and after the job so you have a number that proves the improvement - not just our assurance. A contractor who skips this measurement step leaves you guessing whether the work made a real difference. We prefer to show you the result directly. It is the most honest way to demonstrate what the work actually accomplished.
We hold a valid Wisconsin Dwelling Contractor license, which you can verify through the DSPS license search before we arrive. That credential means we have met the state's minimum training and insurance requirements. It also means you have a formal path to file a complaint if something ever goes wrong - something you do not have with an unlicensed contractor.
We have worked on homes throughout Eau Claire and the surrounding region, from older Craftsman bungalows near downtown to ranch homes on the south side and newer construction on the edge of town. That local experience means we know what Eau Claire homes look like from the inside and what these Wisconsin winters actually demand from a building envelope.
We work in this community because we understand what Eau Claire homes need and what local homeowners expect from a contractor. That combination of local knowledge and verifiable credentials is what we put in front of every customer.
Wisconsin rebates for air sealing are available through Focus on Energy. The ENERGY STAR Seal and Insulate campaign explains the connection between air sealing and energy savings. For contractor credentials in Wisconsin, use the DSPS license lookup.
