Get answers to common questions about insulation services in Lake Mills, Wisconsin.
For our climate, air-sealing combined with high R-value insulation is critical. Blown-in cellulose or fiberglass are excellent choices for attics, as they effectively fill irregular spaces and achieve the recommended R-49 to R-60 level for our zone. This level is crucial to prevent significant heat loss through the roof during our long, cold Wisconsin winters and to manage summer humidity.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for projects like attic work where extreme heat in summer or cold and moisture in winter can complicate installation and material performance. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating and cooling demands hit.
Yes, Focus on Energy, Wisconsin's statewide energy efficiency and renewable resource program, offers cash-back rebates for qualifying insulation upgrades that meet specific performance standards. Additionally, Jefferson County or your local utility (like Alliant Energy or We Energies) may have additional incentives. A reputable local installer will be familiar with these programs and can help you navigate the application process.
Look for a licensed, insured contractor with specific experience in our climate. Ask for local references in towns like Lake Mills, Cambridge, or Jefferson, and verify they perform a thorough energy audit or assessment before quoting. It's also wise to confirm they understand and comply with Wisconsin's building codes and Focus on Energy program requirements to ensure quality and eligibility for incentives.
Not entirely. In many historic Wisconsin homes, air leakage is a major culprit. The most effective approach is a comprehensive "air-seal first, then insulate" strategy. This involves sealing gaps, cracks, and penetrations in the attic, basement rim joists, and around windows and doors before adding new insulation. This stops the cold drafts we feel off Rock Lake and prevents moist indoor air from causing condensation issues within your walls.
