Summer can be a great time. You do not have to indulge in too much home remodeling. Come winter and the DIY bag is put. There is just so much wind, snow and its related monstrosity can do to you.
First you should look to put in storm windows. This is to prevent yourself against the gust of chilling wind. Next, you should look for ad-hoc slanting roof (if you do not have one). This facilitates brushing away of snow. Such snow can pile up and create a lot of issues.
Window AC’s must be removed from the windows. Snow and wind can tighten the boards at the back and make it ineffective.
Drain the water hoses effectively. If you do not do so, chances are that they will suffer cracking once water freezes inside them. Also, clean any leak or remnant in the outside gutter, this will prevent blockage. Insulate water pipes with effective lagging measures.
