Step 3. Remove Old Caulk:

Use your putty knife to scrape away any old caulk from the area carefully you’ll be caulking. Be sure to remove any paint chips as well. As you scrape, use a rag to wipe away any debris. Don’t forget to wear your gloves as you do this!

Step 4. Sand Down Uneven Areas:

Once all of the old caulk is gone, use some sandpaper to smooth out any uneven areas or cracks in the door frame that may have caused water to get inside in the first place. You can also use the sandpaper to smooth down any sharp edges from where you scraped away old caulk. Carefully sand around the edges of the caulked area.

Step 5. Apply Masking Tape:

To keep your freshly applied caulk from getting all over the place, use masking tape to cover the area around it. This will make it easier to clean up any excess caulk later on. Another tip is to use a lighter to help the tape stick better.

Step 6. Apply New Caulk:

Once you’ve prepped the door frame, apply a bead of new caulking along the cracks and seams. Use your finger or an old rag to spread evenly and smooth out any air bubbles that may have formed. You can also use a damp sponge to help create a more uniform look.

Step 7. Remove Masking Tape:

Once you’re done applying the new caulk, carefully remove the masking tape before it dries. Make sure there aren’t any air bubbles left and that the caulk is evenly distributed. If any fixings are required, now is the time to add them.

Step 8. Allow to Dry:

Allow the new caulk to dry for at least 24 hours before touching or applying anything else on top of it. You can use a fan to speed up the drying process. Just make sure that the fan isn’t blowing directly onto your door, as this could cause the caulk to dry unevenly.

Step 9. Clean Up:

Once the caulk has dried, you can use a damp rag to clean up any residue from around the door frame and window sills. Use a putty knife to scrape away any excess caulk that may have dried on the surface. Don’t forget to remove the drop cloth or newspaper that you have used to protect your floor.

5 Things You Should Avoid

1. Don’t ignore the issue. If you don’t fix a leaky door now, it will only cause more damage down the road.

2. Don’t use duct tape or other quick fixes to try and patch the gap. These are unreliable long-term solutions and can often worsen the problem when they fail.

3. Avoid using too much caulk. This can be counterproductive as it can create a gasket effect that prevents water from draining away from your door properly and actually creates a bigger leak instead of fixing it!

4. Try not to paint over any cracks in the wood of the door or frame, as this could cause them to worsen over time due to moisture buildup beneath the paint layer.

5. Don’t try and fix a leaky door yourself if you don’t know what you’re doing. It’s always best to hire a professional for large or complex projects, as they have the right tools and experience to get the job done correctly. This will save you time, money, and potential stress in the long run!
