Pool Resurfacing in Costa Mesa, CA, From Mesa Verde to the Eastside
Aqua Creations provides pool resurfacing in Costa Mesa, CA, for backyard pools, spas, and the pools at apartment buildings and HOAs on both sides of the 405 and the 55. Most of the city drinks Mesa Water District groundwater, and the shared pools here go through the Orange County Health Care Agency.

Coastal air and a dry summer on Costa Mesa pools
Costa Mesa sits a few miles inland from Newport Harbor, so its pools live in coastal air. NOAA’s Newport Beach Harbor station, about 5 miles south of central Costa Mesa, has a normal August high of 73.3°F. At the Tustin Irvine Ranch station, about 9 miles inland to the east, the normal August high is 87.3°F.
Costa Mesa falls between those two numbers and leans toward the coast. That means milder water temperatures than inland Orange County, but salt in the air and sun that still adds up over a dry summer.

Salt settles on everything
Ocean air leaves a fine salt film on coping, rails, and ladders. It ends up in the water too, and a worn, porous plaster surface is the part that soaks it up.
Mild water, slower to dry
Cooler coastal days keep the pool comfortable, but a damp deck and shaded corners give algae more time on a rough surface.
A dry, sunny summer
The harbor station averages well under half an inch of rain from May through September. Months of sun on the water fade an older finish.
A customer review
Our pool was resurfaced with Aqua Creations fiberglass process. Kyle, Eric and the whole crew were great. Emptied the pool on Monday and they finished on Friday. Pool is beautiful. Highly recommend.
Costa Mesa’s neighbors, and how their pools differ
Three cities touch Costa Mesa on the coast side and inland. Same county process for shared pools, different air and water.
Newport Beach
Home of the NOAA harbor station, where the normal August high is 73.3°F. Pools on the harbor sit right in the salt air.

Mesa Water’s groundwater, and what it does to a pool surface
Moderately hard on average, harder at the top of the range
Mesa Water District serves most of Costa Mesa from local groundwater, supplemented by the Mesa Water Reliability Facility, which uses nanofiltration to strip the amber tint out of deep source water. Its 2026 report puts average hardness at 113 mg/L, which the USGS scale calls moderately hard, with readings from 20.6 to 293 mg/L.
On plaster, those minerals find the pores and build into scale, most of all at the waterline where water evaporates and gets topped off. A smooth, non-porous fiberglass surface gives scale much less to hold on to, so what forms wipes away more easily. Parts of Costa Mesa are served by Irvine Ranch Water District instead, whose water runs harder; the Irvine card above has those figures. Plaster is still the most common finish, and our plaster, gunite, and pebble pool resurfacing page explains when an existing plaster pool is a good candidate for a new surface. For the fiberglass side, read about fiberglass pool resurfacing.

Resurfacing an apartment or HOA pool in Costa Mesa
A public pool in Costa Mesa goes through the Orange County Health Care Agency. Its replaster page says the work needs an application, agency approval, and a scheduled inspection before it begins, with one application for each pool and each spa.
The county lists white plaster, fiberglass, or other approved finishes for this work. Public pools follow the county’s approved finish list, so we do not offer custom colors on hotel, apartment, or HOA pools. For property managers, our apartment pool resurfacing page covers the rest.
