Covered boat, RV & jetski winter storage for the Madison area - owner onsite, family-run

No. All storage, both concrete and dirt, is covered but not temperature-controlled. You are responsible for fully winterizing your boat (engine, water systems, bilge) before drop-off.

Access is limited and by appointment. Buildings stay locked; with 72 hours' notice we can open a building during posted access hours. Because boats are stored in rows, we can't guarantee your boat can be reached or removed before spring. Early removal can be requested at least 30 days ahead but isn't guaranteed.

Yes. Proof of insurance must be uploaded before drop-off (a declarations page works), and the policy must cover the boat while it's stored with us. Grassland Valley does not provide coverage for stored vessels. You rent a covered space. You keep responsibility for your boat, and your own insurance covers it.

We accept check, Zelle, and Venmo. A 50% non-refundable deposit reserves your spot, and the balance is due at drop-off. Credit cards are not accepted.

No. We provide only storage. You are responsible for winterizing your boat before drop-off and de-winterizing it after spring pickup. We do not offer shrink-wrap, fogging, antifreeze services, or any mechanical work.

Winterize per the manufacturer's recommendations (engine, water systems, fuel). Disconnect batteries. Close propane tanks at the valve. No portable fuel containers, propane cylinders, or other flammable or hazardous materials. Remove food, perishables, and trash. Secure any cover or shrink wrap. Upload proof of insurance beforehand. No mechanical work, running engines, or generators on the property.

Schedule your pickup within the pickup window at least 7 days in advance. Pickups go front to back since boats are stored in rows, and you hitch up and remove your own boat. Your exact start and end dates are set in your storage agreement. To extend, request it in writing at least 30 days before your end date. Boats left past the end date incur holdover charges. The season runs September through May, with flexibility on the start and end dates.

No fixed limits, we accommodate boats of all lengths, heights, and types. For particularly oversized vessels, contact us so we can confirm the best available spot and confirm pricing.
