To protect the finish on your windowsills, we begin by gently removing away the masonry surface around the crack.

Next, clean any dust from the windows to be mended. A clean line surface will guarantee that your new caulk will last longer.

Then, using a quality sealing product, repair the space you’ve shown in your sill. Fill the gaps with a good quantity of sealant using a caulk gun. Remove any overhangs with a putty knife and spread the extra caulk.

Lastly, polish the seams for an airtight seal and a clean look.
