They came out the same week I called, measured the attic, and gave me a written quote the same day. The crew finished in about four hours and cleaned up completely. My first heating bill after the work was noticeably lower than the year before.
Marcus T., Decatur — Attic Insulation
I had cold floors every winter in my 1960s ranch and figured it was just how old houses are. After they spray-foamed the crawl space, the first floor is warmer than it has ever been. Wish I had done it five years ago.
Linda R., Jacksonville — Crawl Space Insulation
The estimate was clear, the timeline was accurate, and they did not try to upsell me on anything I did not need. The blown-in they added to the attic made a real difference in how the upstairs rooms feel in both summer and winter.

If you can see the attic floor joists when you look in, the insulation level is too low for Springfield's climate. Insulation installed before 1990 may have settled or become moisture-damaged and should be inspected.
Clay-heavy Illinois soil holds moisture, and Springfield's spring thaw pushes that moisture into uninsulated crawl spaces. Unsealed crawl spaces are the leading cause of cold floors and musty odors in central Illinois homes.
Air sealing closes the gaps that allow conditioned air to escape; insulation slows heat transfer through surfaces. Both are needed, and adding insulation without sealing air leaks first significantly reduces the benefit. The{' '} The U.S. Department of Energy estimates that air sealing combined with insulation can cut heating and cooling costs by 10 to 20 percent.
Homes from that era were built with little or no wall insulation and minimal attic coverage by today's standards. Insulating a home like this is one of the highest-return improvements available, and Springfield homeowners in older neighborhoods typically notice a real difference within the first winter.
Ameren Illinois, which serves most of Springfield, offers rebates for qualifying insulation upgrades. Federal tax credits under the Inflation Reduction Act can also cover up to 30 percent of project costs, up to an annual cap. Ask your contractor before signing anything.
Ice dams form when heat escapes through an under-insulated attic and melts roof snow unevenly. The meltwater refreezes at the cold roof edge and can back up under shingles. Proper attic insulation removes the heat source that causes them to form.

If your bills increase significantly in January and February without a change in how you use your home, heat is escaping. The attic and crawl space are the first places to check. In most older Springfield homes, improving insulation in those two areas resolves most of the bill creep.
Rooms directly below an under-insulated attic are the most affected by seasonal temperature swings. In summer, an attic with thin insulation acts like an oven above your ceiling. In winter, it becomes a path for warm air to escape. Adding attic insulation is the most direct solution.
Musty smells often come from moisture entering through an unsealed crawl space or basement rim joist. While it is not strictly an insulation issue, spray foam on the rim joist and a vapor barrier in the crawl space both block the pathway that moist outdoor air uses to enter your home.
Spray foam is the better choice where both insulation and air sealing are needed in a single step, particularly in crawl spaces, rim joists, and areas exposed to moisture. Blown-in is more cost-effective for open attic floors where air sealing can be done separately first.

Springfield is the state capital of Illinois, home to roughly 114,000 people and a community with deep roots and a stable long-term population. As the seat of Illinois state government, the city draws thousands of residents who work for state agencies and plan to stay for decades, which means the homes here are invested in, cared for, and worth maintaining well. You can learn more about the city at the Springfield, Illinois Wikipedia page.
A large share of Springfield's housing stock was built before 1960, including the brick homes found in older neighborhoods like Iles Park and Aristocracy Hill, and the ranch-style homes that spread across the south and west sides in the postwar decades. These homes have character, but they were built under insulation standards that are a fraction of what is recommended today. The Lincoln Home National Historic Site is a reminder of just how old some of Springfield's residential neighborhoods are, and many homes in the surrounding blocks have not had a serious insulation upgrade since they were built.
Springfield's flat terrain means wind, rain, and temperature swings hit homes directly with little natural protection. The city averages around 20 inches of snow per year, and the frost depth in central Illinois reaches 30 to 40 inches, putting real stress on foundations and anything buried in the soil. The National Weather Service Springfield climate page documents the range of conditions that Springfield homes need to withstand across all four seasons. The Illinois State Capitol building, visible from much of downtown, is a useful landmark for understanding where the city's oldest and densest residential neighborhoods begin.
Whether you are a few blocks from the Abraham Lincoln Presidential Library and Museum or out in a newer subdivision on the city's north side, Springfield Insulation Company serves homes of every age and style. Our crews know the housing stock here, the typical problem areas in homes of different eras, and how Springfield's climate demands more from a home's thermal envelope than milder markets require.
