Replacing Exterior Door Weatherstripping
Have you noticed a chilly draft seeping around the front door as colder weather settles in? If so, there’s a good chance the weatherstripping needs to be replaced. As every home inspector will tell you, replacing worn or damaged weatherstripping is crucial to maintaining a warm and cozy wintertime home environment. Proper weatherstripping helps make your home feel comfortable, reduces energy use, and decreases the workload for your furnace. The home inspection experts at Sky Blue Inspections offer the following advice and encourage you to check and replace worn weatherstripping before the cold weather settles in.

Steps to replace your weatherstripping.
- Prepare the area
Remove as much dirt and debris as possible. Clean the area with hot, soapy water. Use sandpaper or stronger solvents to eliminate any residue that the hot, soapy water doesn’t remove.
- Tighten your door hinges.
People often overlook their door hinges. Pull on the door handle to check for any play or looseness. Tightening the hinges helps ensure the door sits properly in its frame and closes correctly.

- Take measurements and determine the type of weatherstripping you need.
Measure the width and height of your door opening to determine how much weatherstripping you’ll need. Many modern doors use similar products. Identify the required products and the quantities needed. Most big-box stores offer several options and kits for replacing popular and commonly used products. Different choices of weatherstripping have advantages and disadvantages but now is not the time to be cheap. Spend the money and buy the best products for your job.
- Remove the old weatherstripping and door sweep.
The weatherstripping and door sweep on most modern doors are usually installed by being pressed or inserted into a slot in the door frame or door itself. Most of the time, you can simply pull the old weatherstripping out with little effort, unless it has been glued in place with paint.
Door sweeps can sometimes be removed while the door is still in place. If this proves too difficult, it might be quicker to take the door off the hinges. You may need some extra assistance with this.

- Remeasure and cut the weatherstripping to length.
The pre-cut replacement weatherstripping is usually a bit longer than the actual door opening. Remeasure and cut the weatherstripping to the correct length. Check the length and make adjustments if needed for the best fit. Slide the new weatherstripping into the proper slot in the frame. Double-check the length of the door sweep and cut it as needed.
- Confirm fit and function
Open and close your door to ensure the fit and function of your new weatherstripping are correct. Keep in mind that the new weatherstripping may make your door harder to open and close at first. Over time, this will improve as the weatherstripping settles into place.
