Step 2: Get the Caulk Gun Ready

Get the Caulk Gun Ready

This step doesn’t take much of your time. If you don’t have a caulk gun and tube, you can head to any local store nearby to get them.

Once you get them, before you begin the process, put the tube into the caulk gun. Ensure both items are a good match or fit perfectly so the caulk would spray equally on the leaks.

Afterward, cut off the tip of the caulk nozzle, but if the leaks passage is not quite big, cut out a little with a few inches. That will work great for the most significant cracks.

If you want the caulk to come out more, you can cut the nozzle further.

Step 3: To Break the Seal

It is essential to create a hole through its seal to determine how the caulk overflows. For you to be able to cut open the nozzle, you can insert the tip of a nail inside.

After that, push it down until notice it has to break through the seal.

Step 4: Apply the Caulk

Apply the Caulk

This step is an important part you must not miss – it’s time to apply and seal the leak. Use the gun to spray the caulk, move it at a slow pace along the crack area. Do not apply much pressure on the trigger when carrying out this task.

After you have sealed the leaks, you should apply the caulk at the frame part to prevent any future damages.

Once you have done everything mentioned above, use a spatula to smoothen the caulk. This measure is to make it flat on the window surface and unnoticeable.

Step 5: Clean Up the Left Over caulk

After you are done, use a clean paper towel to wipe out the caulk on the nozzle and around the tube as well before it dries up. Doing this will keep the equipment safe for use next time without hassles.

How to Fix Leaking Window Frames

Repairing a window frame can also prevent window leaks. But you need to identify if the window is leaking from the window frame. To pinpoint this, you need someone to spray the window with water while you take a closer look to know where it leaks.

Use a putty knife to take out any damaged woods, and then use epoxy wood filler to fix the open space. Then replace the damaged trim, and attach it back with a nail to the window frame. Ensure to do this carefully.

Get a waterproof caulk, apply it to the edges, and then leave it for some time to dry. Afterward, paint the window frame with a matching color as the previous one.
