Serving Urbana, IL and surrounding areas. (217) 207-0899
Your Urbana home loses heated air through gaps you cannot see - around outlets, attic hatches, and plumbing penetrations. We find every gap, seal it, and test before and after to prove the work actually made a difference.
Air sealing in Urbana means finding every gap, crack, and opening in your home's attic, basement, and walls and closing them so outside air cannot sneak in uninvited, most jobs are completed in a single day with no disruption to your living space.
Most Urbana homes - especially those built before 1980 - have gaps around old plumbing, wiring chases, attic hatches, and framing that were never sealed when the house was built. Those gaps let the heated air your furnace produces escape and pull cold air in to replace it. Air sealing in Urbana closes those pathways directly. According to the U.S. Department of Energy, air leaks account for 25 to 40 percent of the energy used for heating and cooling in a typical home.
Air sealing works best alongside insulation. If you have not had attic air sealing or basement insulation addressed, combining those services in one visit is often the most efficient approach.
Urbana winters are genuinely harsh, and if your gas or electric bill jumps dramatically during the coldest months, conditioned air is likely escaping and cold air is rushing in to replace it. If your bills seem high compared to neighbors with similar-sized homes, air leaks are one of the first things worth investigating.
Hold your hand near an electrical outlet on an exterior wall on a cold day - if you feel cool air, that is a gap behind the outlet cover connecting directly to outside. The same test works near baseboards, around the attic hatch, and along the top of interior walls. These are common leak points in Urbana's older housing stock.
If your upstairs rooms are stuffy in summer and cold in winter no matter how you set the thermostat, the attic above them is likely leaking air in both directions. In older Urbana homes, attic floors often have gaps around light fixtures and plumbing stacks that were never sealed when the house was built.
Urbana's humid summers mean that if warm, moist outdoor air is getting into your home through gaps, it can condense on cooler surfaces and create conditions for mold. A musty smell in a basement or crawl space, or persistent condensation on interior windows in summer, can both point to air infiltration problems that sealing would address.
Our air sealing service starts with a blower door test - a measurement that tells us exactly how leaky your home is before we touch anything. From there we work systematically through your attic, basement, and any identified areas, applying foam and caulk to seal gaps around pipes, wires, ducts, and framing. We test again when the work is finished so you have before-and-after numbers in writing.
Many homeowners combine air sealing with a full insulation upgrade. We often pair this service with attic air sealing for a focused approach to the attic plane, or bundle it with basement insulation to address the full envelope from top to bottom in one project. The combination almost always delivers better results than either service alone.
Targets gaps around light fixtures, plumbing stacks, and top plates where the most conditioned air escapes in Urbana's cold winters.
Closes the gap where the framing meets the foundation - a major source of cold-air infiltration in older homes.
A systematic seal of every identified gap from attic to crawl space, confirmed with before-and-after blower door testing.
Combines gap sealing and insulation in one visit for homeowners who want to address both problems at the same time.
Urbana sits in climate zone 5A - cold and humid - and regularly sees temperatures drop into the single digits in January and February. That kind of cold puts enormous pressure on a leaky home. A large share of Urbana's housing was built before 1980, and many homes date back to the 1920s through 1950s - built before energy efficiency was a design priority, with gaps around old plumbing chases, knob-and-tube wiring paths, and attic knee walls that have never been sealed. If your home is more than 40 years old and has never had an energy assessment, there is a very good chance it has significant air leaks that are costing you money every month.
We serve homeowners throughout the Urbana area, including Rantoul and Mahomet. Urbana's humid summers add a second reason to seal: the same gaps that let cold air in during January let hot, humid air in during July - and that moisture can lead to musty smells and slow damage in basements and crawl spaces. The Building Performance Institute sets the national standard for home energy professionals, including how to seal homes safely without creating ventilation problems.
We reply within one business day. During your first call we ask about your home's age, size, and any comfort problems you have noticed - so the assessment technician arrives with the right tools and knows where to start.
A trained technician visits your home, runs a blower door test to measure exactly how leaky the house is, and maps every significant gap before any work is discussed. This visit typically takes one to two hours and costs you nothing.
You receive a written estimate covering what was found, what work is recommended, the total cost, and whether Ameren Illinois rebates apply to your project. We walk you through the rebate details before you commit to anything.
The crew seals all identified gaps with foam and caulk. Before leaving, we run a second blower door test and show you the before-and-after numbers in writing - so you have proof the work actually improved your home's performance.
Free estimate, no pressure. We check your Ameren rebate eligibility at the same visit and reply within one business day.
(217) 207-0899We measure air leakage before we start and again after we finish. You see the actual numbers on paper - not just our assurance that the work was done well. This is the clearest sign of a professional job and the documentation you need for rebate and tax credit applications.
We are familiar with Ameren Illinois home energy efficiency programs and walk every Urbana customer through rebate eligibility before the estimate is signed. Knowing your real out-of-pocket cost upfront is how we do business. Ameren Illinois program
Urbana's pre-1980 homes have specific gap patterns - old plumbing chases, knob-and-tube wiring paths, and uninsulated attic hatches that contractors unfamiliar with this era miss. We have worked in enough Champaign County homes from this period to know exactly where to look.
We assess your home's ventilation before sealing and confirm the house can breathe safely after the work is done. A sealed home that lacks fresh air exchange creates new problems - we follow DOE ventilation guidelines to make sure that does not happen.
Every one of these points connects to the same commitment: we show the work, we know the houses, and we handle the details - rebate enrollment, ventilation safety, and documented results - that distinguish a professional job from a quick patch. That is why Urbana and Champaign County homeowners come back and send their neighbors our way.
