Get answers to common questions about insulation services in Oak Lawn, Illinois.
For most older homes in Oak Lawn, blown-in cellulose or fiberglass insulation in the attic is highly cost-effective. It provides excellent thermal resistance (R-value) for our Illinois climate and can be installed over existing insulation to seal gaps. This upgrade often qualifies for local utility rebates from ComEd or Nicor Gas, improving the payback period.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is crucial for proper installation and allows for adequate attic ventilation. Scheduling during these shoulder seasons also avoids the extreme summer heat in the attic and the winter rush when homeowners are dealing with high heating bills.
Yes, Oak Lawn follows the Illinois Energy Conservation Code, which mandates specific minimum R-values for different parts of your home. While basic retrofit insulation in an existing attic often doesn't require a permit, significant alterations or adding insulation to exterior walls might. A reputable local contractor will know the Village of Oak Lawn's requirements and handle any necessary permits.
Look for licensed, insured contractors with strong local references in southwest suburbs. Verify they perform a thorough energy audit or inspection first. It's crucial they check for and address attic ventilation and existing moisture issues common in our climate. Also, ensure they are certified by manufacturers (like Owens Corning) and inquire about their familiarity with Illinois rebate program paperwork.
This is a common concern. Start with a professional energy assessment, which many Oak Lawn contractors offer. They will use tools like thermal cameras to identify heat loss areas, check your attic's current R-value against the recommended R-49 for our zone, and assess air leakage. This diagnosis will pinpoint whether insufficient insulation, air sealing, or mechanical systems are the primary cause of your high bills.
