Pool renovation in Houston

What a pool renovation usually includes

• Resurfacing (replastering). A new interior finish: plaster, quartz or pebble. Angi’s Houston resurfacing page (updated April 2026) puts the average at $10,846, with most homeowners spending $5,916–$14,790.^[1] See pool resurfacing in Katy for a finish-by-finish breakdown.
• Waterline tile and coping. A Houston plastering company’s FAQ puts retiling at $3,000–$8,000 and coping replacement at $3,000–$10,000.^[2] More on the Woodlands tile & coping page.
• Deck resurfacing. A Houston pool company lists spray-texture coatings from about $4 per sq ft and stamped overlays from about $8.50 per sq ft, plus prep.^[3] See pool remodel & deck resurfacing in Cypress.
• Equipment upgrades. Pumps, filters, heaters and automation. One Houston-area remodeler’s cost guide puts equipment upgrades at $500–$5,000.^[4] See Sugar Land resurfacing & equipment.

What a full remodel costs

A Houston pool builder’s 2026 price table puts a full remodel (surface, tile, coping and deck) at $15,000–$50,000, adding a tanning ledge at $5,000–$10,000 and adding a spa at $8,000–$25,000 or more.^[5] These figures come from companies’ own websites and Angi’s estimates. They’re planning ranges, not quotes. Your price depends on pool size, shell condition, materials and access.

For comparison, a new pool in Houston is a much bigger budget. See the Houston pool cost guide.

Permits: what Houston’s pool code says

Inside City of Houston limits, the city’s amendments to the 2021 International Swimming Pool and Spa Code say anyone who wants to “alter, repair” a pool or spa, or replace a system the code regulates, must first apply for and get the required permit.^[6] Whether your specific scope needs one (for example, a finish-only job versus new plumbing, electrical or a reshaped pool) is a question for your builder and the Houston Permitting Center. Outside the city, your county or suburb sets the rules. See the local pages below.

Draining the pool: where the water goes

Most renovations start with a full drain. Houston’s storm water ordinance bans non-storm-water discharges to the storm sewer, with an affirmative defense for dechlorinated swimming pool discharges.^[7] Texas pool rules also say draining water must go out through an air gap, with no hard connection to the sanitary sewer.^[8] Ask every bidder how they’ll drain, dechlorinate and dispose of the water, and whether that’s in the price.

Questions to ask before you sign

• Will you sound the empty shell for hollow spots before final pricing? How are surprise repairs priced?
• Which finish brand and product are you quoting, and what’s the written warranty?
• Does my scope need a permit? Who pulls it, and is the fee in your bid?
• Are tile, coping, deck and equipment itemized separately?
• Who does any electrical work, and are they licensed for it in Texas?
