How To Seal Sliding Patio Doors

Sliding patio doors are a great way to let in natural light and fresh air, but if they're not properly sealed, they can also let in drafts and pests. This can lead to higher energy bills, as well as discomfort for you and your family. Fortunately, there are a few simple steps you can take to seal sliding patio doors and prevent these problems.

First, inspect the weatherstripping around the door. Weatherstripping is a type of seal that helps to keep air and water out. Over time, weatherstripping can become worn or damaged, which can reduce its effectiveness. If you find any damaged weatherstripping, replace it with new weatherstripping. You can purchase weatherstripping at most hardware stores.

In addition to weatherstripping, you can also apply caulk around the door. Caulk is a type of sealant that helps to fill in gaps and cracks. Apply caulk around the edges of the door, as well as around any screws or nails. Make sure to smooth out the caulk with your finger or a putty knife.

If you have a sliding patio door that is particularly drafty, you can install a door sweep. A door sweep is a type of seal that attaches to the bottom of the door. When the door is closed, the door sweep will create a barrier against drafts. You can purchase door sweeps at most hardware stores.

By following these simple steps, you can seal sliding patio doors and prevent drafts and pests. This will help to reduce your energy bills and make your home more comfortable.

Here are some additional tips for sealing sliding patio doors:

Use a silicone-based caulk. Silicone caulk is more durable and weather-resistant than latex caulk.

Apply caulk in a continuous bead. Do not skip any areas.

Smooth out the caulk with your finger or a putty knife. This will help to create a tight seal.

Allow the caulk to dry completely before opening the door.

By following these tips, you can ensure that your sliding patio doors are properly sealed and will keep out drafts and pests for years to come.
