Wisconsin Home Improvement takes its responsibilities seriously following its business philosophy of:

  • Treat the whole house as a system. Your home's efficiency and comfort often rest on solving a combination of problems. Our trained and BPI certified technicians can identify these flaws by conducting a home performance audit.

  • Educate our customers about how their house works most efficiently. The results of a home energy audit are often quite revealing! We explain these results so that you understand the causes behind drafty rooms, high energy bills or musty smells.

  • No high-pressure sales, just great advice. Our expertise and training gives us the confidence to help you determine the best strategy for improving your home's energy efficiency. With our experience in retrofitting homes, we can provide standard, transparent pricing and an understanding of the process from beginning to completion.

  • Trustworthy and responsive service. We pride ourselves on our honest and straightforward approach to home performance. If you have a problem or a question, we have a prompt response.
