DIY Weatherization For A Greener Home

Creating a greener home involves many steps, one of which is weatherization. Weatherization is the process of sealing air leaks in your home that allow warm air to escape during the winter and cool air to escape during the summer. By sealing these leaks, your home can maintain a more consistent temperature, thus reducing your energy bills and your environmental impact. In this article, we will explore some DIY weatherization techniques to help you create a more energy-efficient home.

Understanding Air Leaks

Before you get started with weatherization, it is important to understand where air leaks occur in your home. Windows and doors are the most common culprits, but air can also leak through walls, the roof, and the foundation. A common way to detect air leaks is to use a candle or smoke stick. Light the candle or smoke stick and hold it near potential leak areas. If the flame flickers or the smoke moves, you have an air leak.

Sealing Windows and Doors

Sealing windows and doors is the most effective way to reduce air leaks in your home. Here’s how to do it:


Weatherstripping is a material that seals gaps around doors and windows. It is made from foam, rubber, or vinyl, and comes in rolls. Weatherstripping is easy to install and can help to reduce your energy bill by up to 15%.

To install weatherstripping, simply measure the length of the gap you want to fill and cut a piece of weatherstripping to that length. Then, peel off the backing and press the weatherstripping into place.


Caulking is a material that is used to fill gaps around windows and doors. It is made from silicone, latex, or acrylic and comes in a tube. Caulking is more permanent than weatherstripping and is ideal for gaps that are too large for weatherstripping.

To apply caulking, first, clean the area around the gap with soap and water. Then, cut the tip of the caulking tube at a 45-degree angle and insert it into a caulking gun. Apply the caulking to the gap, using a steady hand to ensure the caulking is applied evenly.

Draft Stoppers

Draft stoppers are a simple and effective way to reduce air leaks from doors and windows. They are essentially a tube of fabric filled with insulation, usually made of foam. Simply place them against the bottom of your door or window, and they will create a seal.

Sealing Other Areas

Windows and doors are not the only areas where air can escape from your home. Here are some other areas you may need to seal:

Attic Hatches

Attic hatches are often overlooked when it comes to weatherization, but they can be a significant source of air leaks. To seal your attic hatch, first, measure the length and width of the hatch opening. Then, cut a piece of foam board insulation to fit the opening and glue it to the back of the hatch with construction adhesive.

Outlets and Switches

Outlets and switches can also be sources of air leaks. To seal them, first, turn off the power to the outlet or switch. Then, unscrew the cover plate and use foam gaskets to seal the gaps around the edges.


Chimneys can be a significant source of air leaks, especially when they are not in use. To seal your chimney, first, close the damper. Then, cut a piece of foam board insulation to fit the opening and place it over the damper.


Weatherizing your home is a simple and effective way to reduce your environmental impact and save money on your energy bills. By sealing air leaks in your home, you can create a more comfortable living space for you and your family while reducing your carbon footprint.
