Get answers to common questions about insulation services in Mount Vernon, Illinois.
For our Southern Illinois climate with hot, humid summers and cold winters, a balanced approach is key. Proper attic insulation is the top priority, as it prevents significant heat gain in summer and heat loss in winter. We typically recommend achieving an attic R-value of R-49 to R-60, using materials like blown-in cellulose or fiberglass, which also help mitigate the humidity that can lead to mold and ice dams.
Costs vary based on home size, material, and existing conditions, but for a standard attic project in Mount Vernon, homeowners can expect a range of $1,500 to $4,000. Blown-in insulation for walls typically runs $1,000 to $2,500. It's important to get itemized quotes from local contractors, as Illinois' climate zone requirements and potential access challenges in older Mount Vernon homes can affect the final price.
Yes, Mount Vernon residents should first check with Ameren Illinois, the local electric and gas utility, which frequently offers rebates for adding insulation to attics and walls. Additionally, the federal tax credits for energy efficiency (like the 25C credit) remain available, covering 30% of qualified insulation costs up to a $1,200 annual limit. A reputable local installer will be familiar with these programs.
Choose a licensed and insured contractor with proven local experience. They should perform a thorough energy audit or inspection to identify specific air leaks and moisture issues common in our region. Ask for references from nearby projects and verify they understand and follow the 2021 Illinois Energy Conservation Code, which dictates required R-values for our climate zone (Zone 4).
While insulation can be installed year-round, the ideal times are late spring (April-May) and early fall (September-October). These periods offer milder temperatures, making it easier for contractors to work in your attic and for you to ventilate your home during the process. Scheduling during these shoulder seasons also ensures your home is fully prepared before the peak heating and cooling demands of our Southern Illinois summer and winter.
