Big Fish Contracting is a remodeling contractor serving Milwaukee. The company started as a roofer 20 years ago, and it has since grown into a design-build contractor handling remodeling, siding, gutters, windows, and decks. Its craftsmen can increase the functionality of interior living spaces by creating additions like master suites, dining room extensions, and storage spaces. It also remodels kitchens, bathrooms, and basements. Owner Erik Dieringer, alongside an architect and interior designer, uses 3D software to visualize the final design.
