For over two decades, Willow Bay Builders has been building new homes and remodeling in the Fox Cities area. We're not getting older, ...we're getting better! Put our knowledge and experience to work today and see whet dedicated professionals can bring to your project.

"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."

"Everyone who worked on my project were subcontractors. The contact person’s contracting company did not do a good job, then tried 3 times to fix it by remudding and painting. It truly was unacceptable drywall installation. This doubled the length of the project. Corners were cut, critical steps were not done. I was left finally with a finished project done correctly by another drywall installer. It was not a pleasant experience, and I do not recommend them."

"The job went better then imagined. New footings poured, and one support in the center rebuilt. Done within the budget we setup but done right. Found out we had a lot of sand so I was nice to actually get in and pour real footings."

Basement Remodel questions, answered by experts

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

Assuming you are going for a full remodel for an average-sized basement with a reputable contractor, the process can take up to two weeks or more. Remember that basements have many stairs and often difficult access—it’s not like working in the entryway. The shuttling of materials, increased need for ventilation and safety precautions, and making sure everything can be removed through a doorway all increase time and cost.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
