Mastic Replacement

Mastic Replacement - Caulking Between Coping And Pool Decking

Mastic is the caulking between your pool decking and the coping (brick or stone) around the perimeter of your pool. Maintaining good mastic prevents water from seeping down under your pool decking and behind the shell of your pool. This is especially important to correct before the winter arrives and freezing temperatures turn water into ice, causing damage to your pool.

Signs You Need Mastic Replacement:

  • Visible cracks or separation between pool and deck
  • Pool deck shifting or lifting near the edge
  • Water collecting in the expansion joint
  • Mold or mildew growth along the joint

Pool Mastic FAQs

What happens if I don’t replace my pool mastic?

If damaged or missing mastic isn’t replaced, water can seep between the pool and the deck. Over time, this can cause soil erosion, deck cracking, coping damage, and even pool structure issues. Replacing the mastic helps prevent costly repairs down the line.

How often should pool mastic be replaced?

On average, pool mastic should be replaced every 5 to 10 years, depending on weather conditions, pool usage, and material quality. If you notice cracks, gaps, or water pooling in the expansion joint, it’s a good idea to schedule an inspection.
