Air Sealing for
Comfort & Efficiency

Air Leakage

is Half the Battle

Every gap in a home’s exterior surfaces, from around windows and doors to piping and light fixtures, is an opportunity for air to sneak in and out. If left unrestricted, they typically combine to allow more air in than an open window. 

On a hot summer day or frigid winter night, an open window is the last thing anyone wants. It’s time to close that window.


Why Air Seal Your Home?

  1. Comfort: It’s a joy to walk into a nice cozy home, but drafts and air leaks quickly make a home far less welcoming. It’s your home; you should be comfortable in it.
  2. Efficiency: Leaky homes are like running the heater with a window open. Proper sealing can markedly reduce heating/cooling bills and lower the building’s carbon footprint.
  3. Air Quality: There’s always some air moving in and out of buildings. That air passes through dusty areas like wall cavities and behind window trim. As more air flows through these areas, more dust gets pulled inside.

FAQs for Air Sealing

Do You Fix Drafty Windows?

That Depends

While windows are naturally leaky, the drafty sensation is largely caused by radiant energy loss. Most windows don’t block radiant energy well, so waling by one in the winter will make it feel like there’s a draft. This often leads to disappointing results after air sealing around a window.

We can remove window trim and seal around the window, but we don’t replace or restore window trim. The best way to resolve this is to block airflow and improve insulation with dense pack cellulose.

Can My Home Become Too Air Tight?

It's Possible but Rare

Air sealing homes is important enough to be required in building codes. There also needs to be enough fresh air circulating into a home. The key point is houses aren’t submarines–they leak a little bit of air across a ton of locations. 


Even with the highest quality air sealing and insulation installed at the optimal time during construction, it is extremely rare for a home to become too tight. If this is a concern or we suspect it may be a problem, however, we will conduct an air circulation safety test.

Will I Need to Remove Drywall?

Hopefully Not

In many cases, most of the air leakage occurs in areas we can access without forcing renovations. 

We are as inobtrusive as possible in our work and can typically make a noticeable improvement by sealing leaky areas in the attic and/or basement. 

If we do need to access behind drywall, we have techniques that only require patching after–which is far easier than replacing entire sheets of drywall.


State Rebates & Incentives

Many (though not all) Wisconsin insulation projects are eligible for hundreds of dollars in rebates through the state’s Department of Energy. We typically are able to help at least one client capture a rebate each week.

We are certified to implement these rebates and complete nearly all the paperwork for you. We even instantly discount the rebate from your invoice, so you’re not left waiting for the rebate check to arrive.

Know YOUR Numbers

Planning with general numbers often leads to inaccurate estimations and budgets. That’s one of the many reasons we offer free estimates. Whether you need a quick fix or are planning for work next year, work with actual numbers specific to you.
