Resurfacing or replacing your pool deck
Resurfacing keeps the slab you already have and only pays for a new top, so I always look at it first. The catch is that a new surface only lasts as long as the slab under it. On a deck that's heaving or sinking, you'd be paying twice. If the slab is solid, I'll tell you to resurface. If it's moving, I won't sell you a coating to hide it, because the cracks come back through.
What sets the price of a pool deck
Size is the starting point. After that, the cost depends on tear-out and haul-off, any base repair, the finish, drains and how easily we can get into your backyard. Upkeep counts too, since some finishes cost less now and need redoing sooner. If the budget's tight, I'd rather you cut back on a fancy finish than on the base. Nobody sees the base on day one, but it's what keeps the deck flat and draining for years.
