Hidden gaps in your attic, basement, and walls are letting cold air in and heat out all winter. We find them, close them, and verify the results - so your furnace works less and your home feels warmer.

Air sealing in Clinton means finding and closing the gaps, cracks, and openings in your home where outside air sneaks in and heated air leaks out, using foam, caulk, and weatherstripping, with most homes completed in one to two days. Together those gaps can act like leaving a window cracked open every day from November through March - and your furnace pays the price.
Older Clinton homes are especially affected because they were built before modern energy codes required airtightness. Air sealing is often the highest-impact step you can take before adding insulation, and it pairs directly with attic air sealing for homes where the biggest leaks are above the living space.
The Building Performance Institute sets recognized standards for this kind of work. Learn about BPI certification and what it means for homeowners.
If your gas or electric bill spikes every November and stays elevated through March, air leaks are one of the most common causes. In Clinton's climate, where furnaces run hard for five or six months, even moderate air leakage can add hundreds of dollars to your annual energy costs.
Hold your hand near an electrical outlet on an exterior wall on a cold day. If you feel cool air, that is air leakage behind the wall. The same is true near baseboards, window trim, or below doors. These visible symptoms point to a larger network of gaps behind them.
Clinton's proximity to the Mississippi River means indoor air tends to carry more moisture than in drier parts of Iowa. When warm, humid air leaks into a cold attic in winter, it condenses. Over time that moisture causes frost, mold, or wood rot - and the fix starts with sealing the attic floor.
If one bedroom is always colder than the rest of the house, or if the upstairs feels stuffy in summer even with the air conditioning running, uneven air distribution from leaks is often the cause. Air sealing helps your system distribute comfort evenly rather than fighting a constant battle against outside air.
We start with a diagnostic assessment - and when it is warranted, a blower door test - to find where air is actually moving in and out of your home. The biggest leaks in older homes are usually in the attic floor, around plumbing and electrical penetrations, and at rim joists in the basement. We seal each location with the right material: spray foam for larger gaps and irregular shapes, caulk for narrow cracks, and weatherstripping for operable openings. We also offer standalone attic air sealing for homeowners who want to focus on the attic floor specifically, which is often where the largest savings are found.
Air sealing pairs well with basement insulation - the two together address both the leaks and the uninsulated surfaces at the bottom of your home, which is especially important in Clinton's cold winters. We can assess both in a single visit and quote them together or separately.
Suits homes with high energy bills and multiple drafty areas - covers attic, basement, and living spaces in one comprehensive project.
Best for homes where the attic is the primary source of heat loss - often the single highest-impact sealing location in older Clinton homes.
Ideal for homes with cold basements or floor surfaces - closes the gaps where the floor system meets the foundation wall.
Used when specific areas - around pipes, wires, or recessed lights - are identified as the main problem locations.
Clinton sits in climate zone 6, meaning long, cold winters with average January lows in the single digits and frequent wind chill events that push the feels-like temperature well below zero. When outside air at those temperatures is finding its way into your home through gaps in the attic or basement, your furnace works overtime just to keep up. Air sealing is one of the most direct ways to stop that heat loss - and in Clinton's climate, the payback on the investment tends to come faster than in a milder region. Homeowners in Le Claire and Camanche face the same conditions and report similar results after the work is done.
Clinton's location on the Mississippi River adds a moisture dimension that most Iowa cities do not have. The humidity that comes with that location means air sealing is not just about keeping cold air out - it is also about keeping moist air from moving through your walls and attic where it can condense and cause mold or rot. MidAmerican Energy and Alliant Energy both serve the Clinton area and offer rebates for qualifying energy efficiency work, which can meaningfully reduce the cost of a project like this. Scheduling earlier in the year gives you the best chance of capturing rebates before program funding runs out.
We ask a few basic questions - the age of your home, whether you have an unfinished attic or basement, and what problems you have noticed. We reply within one business day and schedule a visit at your convenience.
We walk through your home and, when warranted, run a blower door test that measures how much air is leaking and helps pinpoint exactly where. This takes one to two hours and requires no preparation on your part.
You receive a written estimate that breaks out the major areas - attic, basement, living spaces - so you can see where the money goes. This is also when to ask about utility rebates and whether a permit will be needed for your project.
The crew seals the identified gaps, and we offer a post-job blower door test so you can see in numbers how much the leakage rate improved. You receive documentation of the work for your records and for any utility rebate applications.
Free assessment. Written estimate before any work begins. No pressure, no obligation.
(563) 206-5767Using a blower door test both before and after sealing, we give you measurable proof that the job improved your home's airtightness - not just our word for it. That documentation also helps with utility rebate applications.
Clinton's riverside location creates moisture conditions that contractors from outside the area sometimes overlook. We choose sealing materials and methods that manage moisture movement as well as temperature - so you are solving the full problem.
We work regularly in Clinton and stay current on rebate programs from MidAmerican Energy and Alliant Energy. We can help you understand what paperwork is needed and what the current programs cover. See current energy efficiency guidance at{" "}energystar.gov.
Clinton's older housing stock is what we work on every week. We know where the gaps hide in homes of that era - around top plates, at rim joists, and through plumbing penetrations - and we know how to reach them without causing unnecessary disruption.
Air sealing is one of those services where the quality of the contractor matters more than most people expect, because the work is invisible once it is done. Our diagnostic-first approach and post-job testing are what separate a verified result from a best guess.
Focuses specifically on the attic floor - often the single location with the biggest air leakage in older Clinton homes.
