Cold weather doesn’t just affect the surface—it affects everything beneath it.
At first, nothing seems wrong. The pool looks the same. The structure feels solid. But once freezing temperatures set in, things begin to change… quietly.
Water expands. Materials shift. Small weaknesses become larger ones.
And in many cases, the first visible signs appear around Pool Coping, where exposure to moisture and temperature changes is constant.
If you’re in Waltham, MA, freeze-thaw cycles throughout the winter can significantly impact pool structures over time.
What Is Freeze Damage in Pools?
Freeze damage happens when water enters small cracks or gaps, freezes, and expands.
As water freezes, it increases in volume—putting pressure on surrounding materials.
When this cycle repeats (freeze → thaw → freeze again), the stress builds up, gradually weakening the structure.
This is especially common around Pool Coping and joints where water can easily seep in.
