Mastic replacement is an important part of pool maintenance that helps protect your pool and deck from water damage. Over time, the sealant (mastic) between your pool’s coping and deck can crack, shrink, or separate, allowing water to seep in and cause structural issues like shifting, cracking, or erosion. Our professional mastic replacement service ensures a watertight seal that keeps moisture out and extends the life of your pool deck. With clean lines and a durable finish, your pool will not only be protected—it will look great too.
