Frequently Asked Questions About Insulation in FDL

Get answers to common questions about insulation services in FDL, Wisconsin.

1What is the best type of insulation for my attic in Fond du Lac, given our cold winters?

For our Wisconsin climate, achieving a high R-value is critical. Blown-in cellulose or fiberglass is often the most effective solution for attics, as it fills irregular spaces and can achieve the recommended R-49 to R-60 for our zone. Spray foam is excellent for air sealing but is typically more expensive; a professional assessment can determine the best balance of air sealing and insulation for your specific home's needs and budget.

2When is the optimal time of year to have insulation installed in the FDL area?

While insulation can be installed year-round, late summer and early fall are ideal in Fond du Lac. Scheduling during this period ensures the work is completed before the harsh winter sets in, allowing you to capture energy savings during the coldest months. It also avoids the peak winter rush when contractors are busiest with emergency heat loss issues.

3Are there any local Wisconsin or Fond du Lac programs that help with insulation costs? **Question:** Are there any local Wisconsin or Fond du Lac programs that help with insulation costs?

Yes, Focus on Energy, Wisconsin's statewide energy efficiency and renewable resource program, offers cash-back incentives for homeowners who install qualifying insulation upgrades. Additionally, local utilities like Wisconsin Public Service (WPS) and Alliant Energy often have their own rebate programs. It's crucial to work with a registered Focus on Energy trade ally contractor to ensure you qualify.

4How do I choose a reliable insulation contractor in Fond du Lac?

Always verify that the contractor is licensed, insured, and specifically registered as a Focus on Energy trade ally to access rebates. Ask for local references in the FDL area and check reviews to see their experience with older homes common in our region. A trustworthy contractor will provide a detailed, written estimate that includes the R-value to be achieved, not just the inches of material.

5My house is drafty. Will adding more insulation to my walls alone solve the problem?

Not necessarily. In many older Fond du Lac homes, air leakage is a major contributor to drafts and high heating bills. Insulation resists heat flow, but air sealing (caulking, sealing gaps around windows, doors, and penetrations) stops the cold air infiltration. A comprehensive energy audit, often available through Focus on Energy, is the best first step to identify the specific air leaks and insulation deficiencies in your home.
