Get answers to common questions about insulation services in Lemont, Illinois.
For Lemont's humid summers and cold winters, a combination of air sealing and high-performance insulation is ideal. We typically recommend blown-in cellulose or fiberglass for attics because they provide excellent coverage over our older, irregularly-framed homes and achieve the recommended R-49 to R-60 value for our climate zone (Zone 5). Proper air sealing before insulating is critical to prevent moisture issues common in our seasonal humidity swings.
For a standard 1,500 sq ft attic in Lemont, adding or upgrading insulation typically ranges from $1,500 to $3,500, depending on material, existing conditions, and the required R-value. Homeowners should check for current rebates from ComEd and Nicor Gas, which often offer incentives for insulation upgrades. Additionally, the federal tax credits for energy efficiency (like the 25C credit) can provide significant savings on qualifying materials.
While insulation can be installed year-round, the optimal times in Lemont are late spring (May-June) and early fall (September-October). These periods avoid the extreme attic heat of midsummer, which can be hazardous for installers, and the deep cold of winter. Scheduling during these milder seasons also ensures your home is properly sealed and insulated before the high heating costs of a Chicagoland winter or the cooling demands of our humid summers.
Always verify the contractor is licensed, insured, and has strong local references in Lemont or the surrounding towns. Choose a provider experienced with our specific housing stock, including historic downtown homes and newer subdivisions, as techniques differ. A reputable contractor will perform a thorough energy audit or inspection, explain local building code requirements (like the Illinois Energy Conservation Code), and provide a detailed, written estimate that includes air sealing.
Not entirely. While adding insulation is crucial, air sealing is the first and most critical step for older homes in Lemont, which often have significant gaps in attics, basements, and around windows. Insulation without air sealing is like wearing a sweater unbuttoned—drafts and moisture will still penetrate. A professional assessment will target these air leaks, especially in balloon-framed historic homes common in the area, to create a comprehensive thermal barrier.
