A drafty window can be not only uncomfortable but also expensive, as it allows cold air to seep into your home, increasing your heating costs. While replacing the window entirely may be a solution, it’s not always necessary or cost-effective. Here are three ways to fix a drafty window and keep your home warm and energy-efficient.

1. Weatherstripping

Weatherstripping is an effective and affordable way to seal gaps around your windows. It involves applying a flexible material, such as adhesive-backed foam tape or V-strip tape, around the window sash to reduce drafts. To start, clean the area where you plan to apply the weatherstripping, then measure and cut the appropriate length of material. Remove any adhesive backing and press the material firmly into place, making sure it is properly aligned with the window sash. Replace any worn weatherstripping as needed.

2. Draft Stoppers

Draft stoppers are designed specifically for reducing drafts from windowsills or other sources. They are made from various materials, such as fabric or plastic tubes filled with insulating materials like sand or polyfill. Typically, they are placed along the bottom edge of the window where drafts are likely to enter. These stoppers can be purchased pre-made or can be easily DIYed using fabric and filling at minimal cost.

To make a draft stopper at home, measure and cut a length of fabric to fit your window sill’s length. Fill the fabric tube with your chosen insulating material, such as rice or polyfill, ensuring that it is densely packed to provide proper insulation. Sew or glue the open ends of the tube closed and press it against the base of your drafty window.

3. Caulking and Sealing

Caulking is another method to create an airtight seal around your windows’ frames in order to minimize drafts. High-quality silicone caulk should be used for this purpose, as it is flexible, resistant to water, and adheres well to various surfaces. Before applying the caulk, clean the window frame thoroughly and remove any old caulking that might prevent proper adhesion. Load the caulk into a caulking gun and apply a continuous bead around the window frame’s edge, smoothing it with a caulk-shaping tool or your finger for a neat finish.

Using these three methods, you can effectively address drafts in your windows without the need to replace the entire window unit. Not only will these fixes help you maintain a comfortable indoor environment, but they can also help reduce energy consumption and overall heating costs.
