Sealing windows and doors

Sustainability Victoria has provided their best tips to sealing gaps under and around doors and windows. Sealing gaps that lead to the outside can help reduce air leakage by 12% so it is important to keeping your home toasty in winter. By stopping the any breeze from the outside getting in or and the warm air inside getting out, not only will it keep your house warm but will help reduce the cost of your heating bill.

Step 1

Check each room in the house for doors and windows leading to the outside. Don’t forget to check bathrooms, toilets and laundries as they often have small windows that can let in a breeze. Take note of whether doors open inwards or outwards and the type of flooring it opens over. This will help when it comes to choosing the right products for your home.

Step 2

The market is filled with products to help fix seal any doors or windows in your home. However a lot of products are designed to be fitted specifically to doors so it helps to do some research on the right products for you before going to your local hardware store.

If you need to seal around the edges of your doors (the door jamb), check how big the gap is so that you can choose a seal that will fill the gap. These seals are normally made from foam rubber or plastic and are available in rolls. Each door will use approximately 5 metres to seal, but it pays to measure and count your doors before going shopping.

Step 3

There are a number of different products for each situation and there usage is usually marked on the packaging. Before sealing any door or window, prepare the surface by ensuring it is clean and dry. Dirt and oily residue will prevent adhesive seals from sticking properly.

Tools needed

Although it is not a tough job, you may need some basic tools to seal your doors and windows. The seals may be wider than the door and may need to cut down to size before being attached. When attaching the seal to the door, it’s a good idea to screw the seal onto the door; don’t rely on the adhesive alone.
