Choosing The Right Seal

They work well in busy places. Foam seals are cheap. They are easy to replace. Each type has its own benefits. Choose wisely based on your needs. For more door hardware guides like this, see our full door hardware and locks hub.
Measuring for a Proper Fit is key to success. Use a tape measure. Measure the door’s bottom width. Then measure the height from the floor. Write down these numbers. Check them twice to be sure. A good fit stops drafts. It also keeps out dirt. Always get the correct size for the best results.
Preparing The Area
Begin by removing the old seal carefully. Use a screwdriver to loosen screws. Gently pull the seal away from the threshold. If the seal sticks, use a knife to cut it free. Avoid damaging the door frame. Check for nails or staples holding the seal. Remove them with pliers if needed. The threshold should be clean and clear. If the threshold itself is damaged rather than just the seal, see our guide on repairing a door threshold.
Once the old seal is gone, clean the threshold well. Sweep away dirt and dust. Use a damp cloth to wipe it down. Make sure no debris remains. A clean surface helps the new seal stick better. Dry the area with a towel. Check for any damage or rot. Repair problems before adding a new seal.

Testing The Seal

Regular checks ensure the seal remains effective against moisture and air leaks. If drafts persist after the swap, see our guide on sealing under an exterior door threshold.
Checking For Gaps
Look closely at the door threshold seal. Are there any visible gaps? Gaps can let air and water inside. Use a flashlight to check for gaps. Shine the light through the seal. If you see light, there is a gap. Gaps mean the seal isn’t tight. They might need fixing.
Ensuring Proper Function
Press down on the seal lightly. It should feel firm. A soft seal might not work well. Test the seal by closing the door. Listen for noise. A good seal keeps noise out. If you hear wind or noise, the seal may be loose. Check if the seal is damaged. Look for cracks or wear. A broken seal can’t protect well. Replace it if needed.
