Get answers to common questions about insulation services in Westmont, Illinois.
For Westmont's humid summers and cold winters, a combination of air sealing and attic insulation is critical. We recommend focusing on attic insulation (typically blown-in cellulose or fiberglass to achieve R-49 to R-60) and properly insulating basement rim joists to prevent cold drafts. Addressing air leaks is equally important to manage moisture and improve comfort year-round, aligning with Illinois's energy code requirements for our climate zone.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is optimal for attic work and allows for proper ventilation during installation. Scheduling during these shoulder seasons also helps you prepare your home for the extreme temperatures of our Illinois summer and winter, and you'll avoid the high-demand backlog common in peak summer and late fall.
Yes, Illinois homeowners can access significant incentives through the Illinois Home Performance with ENERGY STAR program, administered by the Illinois Department of Commerce and Economic Opportunity. Additionally, ComEd and Nicor Gas offer rebates for insulation and air sealing improvements. A reputable local contractor will be familiar with these programs and can often help you navigate the application process to reduce your overall project cost.
Always verify that the contractor is licensed, insured, and has strong local references. Look for companies experienced with the specific challenges of older Westmont homes, such as balloon framing or historic preservation considerations. It's also wise to choose a provider who performs a comprehensive energy audit first, as this diagnostic step is crucial for identifying the most cost-effective improvements for your specific home.
Common signs in our climate include drafty rooms, ice dams on the roof in winter, uneven temperatures between floors, and excessively hot upstairs rooms in summer. A professional energy audit, which includes a thermographic scan, is the best way to diagnose insufficient insulation, air leaks, and moisture issues specific to your home's construction. This audit will provide a targeted plan rather than a guess, ensuring your investment addresses the real problems.
