Getting your house winter-ready is something you can never be too careful about in Denver Colorado. It’s best to get heating repair and furnace repair done over the summer or in the early fall. In addition, you will want to ensure your sump pump is in working condition. This is even more important if the summer was very dry. While you are at it, a roof inspection is also necessary. Shingles that are loose should be replaced quickly. Finally, a thorough inspection of your chimney and fireplace is in order. Prior to winter is the time for you to stockpile wood.
