Get answers to common questions about insulation services in Des Plaines, Illinois.
For Des Plaines' cold winters and humid summers, blown-in cellulose or fiberglass is highly recommended for attics due to its superior ability to fill irregular spaces and create a consistent thermal barrier. The recommended R-value for attic insulation in our Illinois climate zone (Zone 5) is R-49 to R-60. A professional can assess your existing insulation and air sealing needs, as proper air sealing is crucial to prevent ice dams in winter and improve overall efficiency.
Costs vary based on home size, insulation type, and area (attic, walls, basement), but Des Plaines homeowners can expect to invest between $1,500 to $4,500 for a professional attic insulation project. Regional material and labor rates influence pricing, and it's important to factor in potential rebates from ComEd or Nicor Gas for Illinois residents, which can significantly offset the upfront cost. Always get detailed, written estimates from local contractors that break down materials, labor, and R-value.
While insulation can be installed year-round, the ideal times in Des Plaines are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is optimal for contractor scheduling and allows the work to be completed before the extreme cold sets in. Planning ahead for a fall installation ensures your home is fully prepared for winter heating efficiency, which is critical for our climate.
Yes, insulation contractors working in Des Plaines must be licensed by the State of Illinois (require a Home Repair and Remodeling Act license) and should carry proper insurance. The work must comply with the 2018 International Energy Conservation Code (IECC), which Illinois follows, mandating specific R-values for different parts of the home. Reputable local providers will handle all necessary permits from the City of Des Plaines Building Division if required for the scope of work.
In Des Plaines, air sealing is the critical first step, especially in older homes. Adding insulation on top of significant air leaks is like wearing a sweater unzipped; you lose the full benefit. Professionals will first seal gaps around penetrations, recessed lights, and the attic floor to prevent warm, moist indoor air from escaping into the cold attic (which causes ice dams). After comprehensive air sealing, adding the correct amount of insulation provides maximum comfort and energy savings.
