Turn Off the Water

Few things will ruin a cabin faster than water damage from undetected plumbing leaks. It can ruin ceilings, floors and walls, leading to repair bills in the thousands. This is especially true if nobody is around to notice it when the leak starts, so it’s essential to shut off the water before you lock up for the season. To do that, look for the main valve near the water meter and turn it clockwise to close it. If it’s stuck, leaks or doesn’t turn on again, hire a plumber to replace it.

If you have a well, turn off the curb stop to stop all water entering the house. Or, you can turn off the circuit breaker that controls the well pump, but even after doing that, you still have to drain water from the interior plumbing if your cabin remains unheated in the winter. Add RV glycol solution to toiletsfloor drains, sink and shower traps to keep them from freezing. If you don’t heat in winter, drain the pipes by attaching a hose to the lowest point in the plumbing, then blow out all the water with an air compressor.

Disconnect Garden Hoses

garden hose that’s left connected to a spigot will trap water inside the spigot. When that water freezes, it can break open the spigot, the hose or both. Sometimes the pipe behind the spigot bursts and sprays hundreds of gallons inside the house. This can happen even with a frost-proof spigot and even if the water supply is off. So always disconnect garden hoses before winter arrives.

Store Boats and Water Sports Equipment

Clean and store boats, dock paraphernalia, dock ladder, life jackets and other water sports equipment. Store outdoor furniture and hammocks. If the cabin is in the snow belt, either cover outdoor tables or tip them up so that they don’t get damaged by the weight or the melting of snow.

Winterize Cabin Furnace

If you leave the heat on, make sure to change your furnace filter to maximize efficiency. A badly clogged air filter can cause the furnace to overheat and shut off. It can be hard to tell with some filters, so consider installing an air filter gauge that lets you know when it’s time to replace the filter.

Trim Overhanging Branches

Trim trees around the cabin so dead branches won’t crash down on the roof because of a windstorm or snowstorm. Trim overgrown branches from bushes growing next to the cabin so snow-laden branches don’t damage the siding or offer shelter to critters seeking a cozy spot to hunker down for the winter.

Keep Mice and Others Pest Out

Look for gaps around the foundation, eaves, soffits, windows, doors and siding. Seal leaks with insulating foam to keep out cold air and pests. Or you can try one of these methods: fill gaps with steel wool, cover with sheet metal, or fill with caulk, plaster or cement. Remove all perishable foods; store canned and dry goods in air-tight/critterproof containers. Close the damper to the fireplace and seal it off to prevent animal invasion. Make sure the chimney cap is secure and undamaged. Mice can enter a building through surprisingly small holes.

Winterize Small Engines

Winterizing small engines starts by dealing with the gas in them. You can either drain the fuel entirely, or you can add a splash of fuel stabilizer and run the engine for a while before storing it.

Empty Flower Pots

If you leave clay, ceramic, or glass pots outside over the winter, you may end up with cracked or broken flowerpots because the moist soil inside them expands when it freezes. Empty the pots or make sure the soil is dry (and keep the pots covered) or take the pots in for the winter.

Protect Appliances

Install a surge protector to protect electronics from power surges caused by lightning strikes. If you don’t have surge protection, unplug computers and major appliances. Leave the door ajar on an unplugged refrigerator to prevent musty odors or mildew from developing. Place a dishtowel in the door to keep it from closing.
