Frequently Asked Questions

Common questions about docks, lifts, and our services.

How much does a dock cost?
Dock pricing depends on the type of system (stationary, floating, or roll-in), the size and layout you need, and any accessories like benches, ladders, or rails. Contact us for a free, no-obligation quote tailored to your waterfront.
What type of dock is best for my lake?
The best dock depends on your shoreline, water depth, and how you use your waterfront. Stationary docks are great for stable shorelines, floating docks work well where water levels change, and roll-in docks offer easy seasonal removal. We'll help you choose the right fit.
Do you remove and install docks seasonally?
Yes! We offer full seasonal installation and removal services. Our team handles everything so your dock is in the water when you need it and safely stored when you don't.
What areas do you serve?
We're based in Oshkosh, Wisconsin and serve the Fox Valley, Northeast Wisconsin, and surrounding lake country. We're also expanding to serve customers nationally.
What materials do you use?
We use aluminum framing for long-lasting quality and maintenance-free polymer decking. Our materials are built to withstand Wisconsin weather year after year.
