Winter can spell big trouble for your home when ice and snow build up in blocked gutters, resulting in ice dams. Clear your gutters of debris before cold weather arrives, then keep an eye on them in freezing temperatures to make sure they stay clear of dangerous amounts of ice.

You can protect your deck from winter weather damage by covering it with a tarp, or applying a water repellant seal before cold weather arrives.

Most sump pumps have an extension hose that removes water from the sump pump basin and diverts it away from the house.

So, keep an eye on your siding during the winter, and attend to small maintenance problems as quickly as you’re able.
