That little joint between your pool deck and coping?
It matters more than you think.
Pool mastic creates a flexible seal that allows your pool and concrete decking to naturally move without constantly pushing against each other.
When it starts cracking, separating, or deteriorating, it may be time to have it replaced.
It’s one of those maintenance items that’s easy to overlook — until it becomes a bigger problem.
If yours is looking rough, Blue Vista can help.
