Get answers to common questions about insulation services in Ontario, Wisconsin.
For our cold Wisconsin climate, the U.S. Department of Energy recommends an attic R-value of R-49 to R-60. This high level of insulation is crucial to combat Ontario's harsh winters, where temperatures frequently drop below freezing, to prevent significant heat loss through the roof. Properly meeting this target reduces heating bills substantially, improves home comfort by eliminating cold drafts, and helps prevent ice dam formation on the roof, a common issue in the region.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather which is optimal for installation and allows contractors to complete work efficiently. Scheduling during these shoulder seasons ensures your home is properly sealed before the peak heating season begins, and you'll avoid the high-demand summer and late-fall rush when contractor schedules fill up quickly.
Yes, Wisconsin homeowners should explore programs like Focus on Energy, which offers cash-back rebates for adding insulation to meet specific R-value targets. Additionally, your local utility, such as Vernon Electric Cooperative or Xcel Energy, may have their own incentive programs. It's always wise to check with your insulation contractor, as reputable local providers are usually well-versed in the latest available rebates and can help you with the application process.
Look for a licensed and insured contractor with specific experience in Wisconsin's climate. They should perform a thorough energy audit or assessment before providing a quote. Check for local references and reviews, and verify they are familiar with Wisconsin's Uniform Dwelling Code for insulation requirements. A trustworthy provider will also clearly explain the differences between insulation types (like blown-in cellulose, fiberglass batts, or spray foam) and which is best for your specific home and budget.
Air sealing should almost always be your first priority, especially in older Wisconsin homes where gaps and cracks can be significant. Adding insulation on top of air leaks is less effective, as the moving air reduces the insulation's performance and can lead to moisture problems within walls. A professional assessment will identify key leakage areas (attic hatches, wiring holes, sill plates) that need sealing before new insulation is installed, ensuring you get the full energy-saving benefit and improved indoor air quality.
