5.0 Michael T. Appleton, WI

Gerry, owner of WIllow Bay Builders is top notch. He provided a detailed quote with a time schedule during the early phase of the project that outshined all competitors when bidding for our project. His team of contractors and suppliers were exceptional. All work was completed on time with adherence to detail. My wife and I couldn't be happier with the end result (a major basement renovation). I would recommend Gerry to anyone looking for quality, time management to expectations and competitive costs. Truly a pleasure to work with.

5.0 Tom H. Appleton, WI

Gerry with his subcontractors did a top notch job.

5.0 Gregory K. Menasha, WI

Gerry was fantastic. Easy to work with, easy to get along with, and everything turned out better than I had imagined. Highly recommended.

5.0 Nathan W. Appleton, WI

Gerry is an exceptional contractor and exceptional human being. As newer homeowners and inexperienced handy persons, Gerry went out of his way to explain processes and provide thoughtful insight into the work being completed. He has a great relationship with his subcontractors and that was prominent when issues arose as they were quickly fixed. We provided Gerry with a professional drawing of the basement and he provided his thoughts and made quality improvements without changing the overall layout. Our basement was built during the COVID pandemic and Gerry stored masks and disinfectant directly outside our front door so all parties involved felt comfortable and safe. During the initial quote was honest about the supply chain disruption and the potential for delay in supplies. Overall, it was fantastic to have an individual flexible and accommodating to the changing environment. The quality of finished basement exceeded our expectations by far. We were skeptical of hiring a general contractor at first, but have no questions since hiring Gerry. If we were to build a home or have another significant remodel, we would hire Gerry again in a heartbeat.

5.0 David W. Kaukauna, WI

Contractor and subcontractors were very professional, concerned that we were satisfied with their work. They all were willing to adapt to changes as the project moved along. Highly recommend Willow Bay.

Response from Company:

5.0 Bill H. De Pere, WI

Gerry did a fantastic job of bringing our vision for our basement space to realality. He s a good communicator with a excellent team behind him. We highly recommend Willow Bay Builders.

N/A Neenah, WI

We are very pleased with the overall experience with Willow Bay Builders. Our basement has undergone a complete transformation from just a few short months ago. We now have an enjoyable, usuable recreation area that is a delight to be in. The quality is comparable, if not superior to the rest of the home. Gerry was very much a professional and a pleasure to work with. He dealt with the difficulty of our duct work/piping and our requests to make the space as close to what the customer wanted as could be expected. We love our new play area and it turned out better than I had anticipated it could be. A couple minor miscommunications arose but overall, very satisfied customers!

N/A Hilbert, WI

Very thorough and did everything as promised. This was a great experience.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
