Get answers to common questions about insulation services in Cortland, Illinois.
For Cortland's climate, with cold winters and hot, humid summers, a combination of air sealing and high R-value insulation is crucial. We typically recommend blown-in cellulose or fiberglass for attics, aiming for an R-value of R-49 to R-60, which meets Illinois energy code recommendations. This level helps keep heat in during our harsh winters and blocks summer heat gain, improving year-round comfort and efficiency.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for projects like attic work where extreme heat in summer or cold and moisture in winter can complicate installation and affect material performance. Scheduling during these shoulder seasons also helps ensure your home is properly sealed before the peak heating and cooling seasons.
Yes, Cortland homeowners should first check for federal tax credits for qualified insulation improvements. Locally, it's essential to contact ComEd and Nicor Gas, as they frequently offer rebates for adding insulation to meet specific R-value targets. Additionally, Illinois' Home Weatherization Assistance Program (IHWAP) may provide aid for income-eligible residents in DeKalb County to improve home energy efficiency.
Always verify the contractor is licensed, insured, and has strong local references. Look for a provider experienced with the specific challenges of older Cortland homes, such as balloon framing or knob-and-tube wiring, which require special handling. We recommend getting 2-3 detailed written estimates that include a scope of work, material specifications (R-values), and a clear breakdown of costs for labor and materials.
Absolutely, uninsulated or poorly insulated walls are a major source of heat loss in Cortland's cold winters. Retrofitting wall insulation, typically done with dense-pack cellulose or injection foam, is minimally disruptive for a professional crew. Small holes are drilled from the exterior or interior, filled, and then meticulously patched, causing much less mess than many homeowners anticipate while significantly improving comfort and reducing those high heating bills.
