Get answers to common questions about insulation services in Glen Ellyn, Illinois.
For Glen Ellyn's climate, with its significant temperature swings, a combination of air sealing and high R-value insulation is key. 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 retain heat in winter, blocks summer heat gain, and properly installed, manages moisture from our humid summers to prevent mold.
For a standard 1,500 sq ft attic in Glen Ellyn, adding or upgrading insulation typically ranges from $1,500 to $3,500, depending on material, existing conditions, and the R-value achieved. Importantly, Glen Ellyn residents can access rebates through the **Illinois Home Performance with ENERGY STAR** program and may qualify for federal tax credits, significantly offsetting the cost when combined with other energy upgrades.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather in Glen Ellyn, which is safer for contractors working in attics and allows for proper assessment without extreme heat or cold. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating and cooling demands of winter and summer.
Always verify the contractor is licensed, insured, and has strong local references. Specifically, ask if they perform a **blower door test** to identify air leaks—a critical step for our climate—and if they are a certified installer for rebate programs like Illinois Home Performance. A reputable Glen Ellyn area contractor will also provide a detailed quote that includes air sealing, material R-value, and a clear explanation of how the work meets local building codes.
Yes, insulating the walls of an older home (common in Glen Ellyn's historic districts) is one of the most impactful upgrades for comfort and energy savings. The most common, minimally invasive method is **dense-pack cellulose injection**, where small holes are drilled in the exterior siding or interior walls to fill the cavity. This effectively reduces drafts, improves the building envelope for our seasonal extremes, and can be done without major interior demolition.
