Get answers to common questions about insulation services in Johnston City, Illinois.
For our Southern Illinois climate with hot, humid summers and cold winters, a balanced approach is key. Prioritizing air sealing and attic insulation is crucial, as heat loss and gain through the roof is a major issue. We typically recommend achieving an attic insulation level of R-49 to R-60, which often means adding dense-pack cellulose or blown-in fiberglass over existing insulation to meet this target and improve year-round comfort.
Costs vary significantly based on the home's size, the area being insulated (attic, walls, crawlspace), and the material chosen. For a typical attic insulation project in a 1,500 sq ft Johnston City home, homeowners can expect a range of $1,500 to $3,500. Local factors like accessibility and the need for old insulation removal can affect the price, but investing in proper insulation offers strong returns through lower energy bills, especially given Ameren Illinois's utility rates.
While insulation can be installed year-round, the ideal times are late spring (April-May) and early fall (September-October). These periods typically offer milder temperatures in Southern Illinois, making it more comfortable for workers to perform thorough air sealing and installation in your attic. Scheduling during these shoulder seasons also ensures your home is prepared for the peak heating and cooling demands of our summer and winter.
Yes, the Illinois Home Weatherization Assistance Program (IHWAP) provides income-eligible homeowners with free energy efficiency upgrades, including insulation. Furthermore, Ameren Illinois's ActOnEnergy® program often offers rebates for insulation improvements that meet specific performance standards. It's important to choose a qualified contractor familiar with these programs, as they must follow specific protocols for the work to be eligible.
Always address air sealing first. Many historic homes in Johnston City have significant air leaks around windows, doors, and attic penetrations that undermine even the best insulation. We perform a thorough assessment to seal these gaps with caulk, foam, and weatherstripping. This stops conditioned air from escaping, reduces moisture intrusion from our humid summers, and ensures that any new insulation you add works at its maximum efficiency.
