The Importance of Detailing Your Boat Before Winter Storage

As the Summer Season comes to a close in New Hampshire, boat owners find themselves with an important question: How should I prepare my boat for the impending Winter months?

While it may be tempting to simply shrink-wrap or store your boat and forget about it until next Spring, proper boat detailing before Winter storage is a crucial step that should not be overlooked.

In this blog, we will explore the reasons why detailing your boat before Winter storage in New Hampshire is not only a smart move, but is also essential for the long-term health and preservation of your boat.

1. Preventing Mold and Mildew

Boats that are not properly cleaned and detailed before Winter storage are at risk of developing mold and mildew problems. The combination of moisture, lack of ventilation, and residual dirt and grime can create an ideal environment for these pesky fungi to thrive. Detailing your boat includes cleaning and sanitizing the interior, removing all food, and ensuring proper ventilation, reducing the risk of mold and mildew growth during the Winter months.

2. Protecting Against Oxidation, Fading, and Cracking

New Hampshire is known for its harsh Winter weather, which can include freezing temperatures, heavy snowfall, and ice. These conditions can take a toll on your boat's exterior and interior. Detailing your boat before Winter storage helps create a protective barrier against the elements on both the exterior and interior surfaces of your boat. A thorough cleaning and protectant put of the hull and topsides will shield your boat's surfaces from the corrosive effects of Winter moisture and UV rays, preventing oxidation, fading, and cracking. Other vulnerable surfaces include the vinyl and leather of your boat, which can be found on exterior decals, and interior seats and dashboards. If these surfaces remain bare during the Winter months, they are susceptible to permanent staining, fading, and cracking, leading to costly repairs heading into the Spring season. 3. Ensuring a Smooth Start to the Boating Season

If you have been a boat owner for multiple years, you know that when Spring arrives, the urge to get back onto the water is unlike any other feeling! When the warm weather starts to roll around, having a well-detailed and maintained boat can make the process much smoother and more enjoyable. Instead of waiting for your Marina or a Detailer to "squeeze you in" for detailing during their Spring Rush, having your boat detailed in the Fall allows for quick turnaround times and ease of mind.

4. Preserving the Value of Your Investment

Your boat is not just a source of enjoyment; it's also an investment. Proper maintenance and detailing can help preserve the value of your boat. A well-maintained and clean boat will fetch a higher resale price if you decide to upgrade or sell it in the future. Neglecting to detail your boat can result in costly repairs and a diminished resale value.

5. Avoiding Costly Repairs

Winterizing your boat is more than just storing it away; it involves a series of important steps, such as engine maintenance, fuel stabilization, and more. With having your boat detailed before storage, you can ask your detailer to inspect the boat thoroughly, to identify any existing issues that need attention. Addressing these problems before Winter sets in can save you from costly and potentially extensive repairs come springtime.


Detailing your boat before Winter storage in New Hampshire is a smart investment in both the short and long term. By protecting your boat from the harsh Winter weather, preventing mold and mildew, preserving its value, avoiding costly repairs, and ensuring a smooth start to the boating season, you'll enjoy many more seasons of fun and worry-free boating. Don't let neglect take its toll on your cherished vessel; instead, invest in professional boat detailing to keep your boat shipshape all year round.
