Pool Resurfacing in San Antonio: Finishes, Costs and Timing

Most San Antonio pools need a new interior surface every 8 to 25 years, depending on the finish and how the water has been kept. When the surface starts to feel rough on your feet, shows gray or brown stains that brushing will not lift, or flakes into the water, resurfacing is usually the fix. This guide covers how to tell your pool is ready, which finishes hold up best in local conditions, what the work costs, and how to plan the project.

Signs your pool needs resurfacing

The clearest signs are a rough or sandpaper-like surface, stains that come back right after you clean them, small chips or hollow-sounding patches, and exposed gray plaster or rebar rust spots. Some owners also notice they are adding more chemicals than they used to, because a porous surface makes the water harder to balance.

Fine surface cracks are common and are usually repaired as part of the job. Long cracks that grow, or walls that have shifted, should be checked before any new finish goes on, because a new surface will not hold over a moving shell.

How San Antonio water and weather affect your surface

San Antonio draws much of its water from the Edwards Aquifer, which is hard, with calcium levels that often run above 200 mg/L. Hard water leaves scale at the waterline and can etch or stain plaster faster than in cities with softer water. Long, hot summers and strong sun add to the wear, and the expansive clay and limestone soils around Bexar County can move a pool shell over time.

In practice, that means finishes with aggregate (quartz or pebble) tend to last longer here than plain white plaster, and keeping calcium, pH and alkalinity in range matters as much as which finish you choose.

Choosing a finish

White plaster (marcite) is the most affordable option and gives a bright, classic look. It is the shortest-lived finish in hard water and needs the most careful chemistry.

Quartz aggregate mixes colored quartz into the plaster. It is harder, resists staining and scale better than plain plaster, and is a strong middle-ground choice for many San Antonio homeowners.

Pebble aggregate (such as PebbleTec or PebbleSheen) is the most durable option and handles hard water and heat well. It costs the most upfront but often has the lowest cost per year of use.

What pool resurfacing costs in San Antonio

For a typical residential pool with about 400 to 600 square feet of interior surface, these are common price ranges:

Crack repair, new waterline tile and coping are usually priced separately. Crack repair often runs a few hundred dollars to about $1,500, and waterline tile replacement commonly adds $2,000 to $4,500. Larger pools, attached spas and lots of steps or benches add surface area and cost.

How the project works

A standard resurfacing job runs about one to two weeks from draining to swimming:

• Inspection and quote: the contractor measures the surface, checks for cracks and hollow spots, and talks through finish options.
• Drain and prep: the pool is drained, the old surface is chipped or ground so the new finish can bond, and cracks are repaired.
• Tile and fittings: waterline tile, coping and lights are addressed if they are part of the job.
• Application: the new finish goes on in a single day so it cures evenly.
• Fill and start-up: the pool is refilled right away, then the water is balanced and the surface is brushed daily during the first weeks.

Mild weather, roughly fall through spring, is the easiest time to schedule. Peak summer heat makes curing harder and puts the pool out of use when you most want it.

Questions to ask before you hire

Ask each contractor how they prepare the old surface, what finish brand and thickness they use, how they handle start-up chemistry, what the written warranty covers, and how they deal with cracks they find after draining. Getting two or three detailed quotes for the same finish makes them much easier to compare.
