If you’ve ever noticed a breeze coming from underneath your front door or the side of a window, you know how unpleasant it can be. Those drafts are expensive, too, wasting energy year-round as your air conditioning and heating systems struggle to maintain a comfortable temperature in your home.

While there are ways to renovate your home to remedy these issues, you may not always have the time, budget, or DIY skills to fix these problems with a big project like installing new doors, windows, or additional insulation. And that’s not always what’s needed, either. Window sealing and weather stripping tape can be very effective at closing small gaps in windows and door frames.
