For us the contractor number itself didn’t really blow up. Resurfacing and a bit of deck repair landed pretty close to what we were told. What caught me off guard was everything that came after, once the pool actually looked new again. Suddenly every little issue you used to ignore feels louder. The first few weekends after the makeover we had friends over, higher bather load than normal, and the water went dull fast. Not green, just this annoying haze that made the fresh surface look kinda meh.
That turned into extra spending on chemicals and maintenance tweaks I hadn’t planned. Chlorine demand was higher, pH kept drifting up around 7.7, and the filter pressure was climbing quicker than before. I ended up using aquadoc flocculant after one busy weekend just to reset things. Shut the pump off overnight, vacuumed a pile of gunk the next morning, and the water finally matched how new the pool looked. It actually made me realize how much clean water matters once everything else is updated.
So yeah, the makeover cost stayed close on paper, but plan a buffer for the “now I can see everything” phase. New surfaces plus old habits equals extra chemistry until you get it dialed in. That part doesnt get mentioned in contractor quotes, but it’s real. Anyone else notice maintenance costs bump up right after a remodel?
