Pool Replastering in El Lago, Texas

Replastering pools behind homes from the 1960s
El Lago was started in the 1950s and incorporated in 1961, and by the Handbook of Texas's account it grew from 750 people in 1967 to 3,550 by 1975 as workers came to the nearby Johnson Space Center. The housing still shows it. In the Census Bureau's 2020–2024 survey, about 693 of El Lago's 1,268 housing units (54.7%) were built before 1980 and about 469 (37.0%) in the 1960s alone, with a median year of 1977 from a small sample (±7 years). About 70.0% are single-family detached houses and about 23.4% sit in buildings of 20 or more units, and owners live in 79.5% of the occupied homes. For July 1, 2025, the Bureau's estimate is 2,984 residents.
What a new coat of plaster does
The National Plasterers Council notes that a pool's interior finish has no structural rating and isn't considered part of the pool structure, while its Technical Bulletin 7 says a pool's watertightness comes from the concrete or shotcrete structure and the finish together. Replastering renews the finish half of that pairing.
The current plastering standard
A revised national standard for that work came out on April 14, 2025: ANSI/PHTA/NPC/ICC-12 2025, issued jointly by the plasterers' council, the International Code Council and the Pool & Hot Tub Alliance. It sets out the materials for a cement-based finish on home and public pools and spas and the ways of applying and finishing it, drawn from common accepted trade practice.

(281) 694-4352Permits and fences for a pool replaster
The City of El Lago handles all the permitting for swimming pools in town, its water district confirms, and the district allows no construction on its own or other utility easements. The City's permit procedures, as of March 18, 2020, require a permit for swimming pools and spas with two sets of construction plans, and inspections of the pool and equipment locations and the plumbing, gas and electrical connections. They also call for permits for remodeling and for any change to a structure's form or integrity, and they say a general contractor's permit is required for "ALL work (cosmetic included)" worth $20,000 or more.
None of that names replastering, so check with the El Lago Building Department before a replaster is booked. Work done without a permit is halted and fined double the permit fee, and every contractor registers with the City each year. The City's list of current codes carries the 2018 international building, residential, plumbing, fuel gas, mechanical and energy codes, the 2015 fire code and the 2020 National Electrical Code, and it names no swimming pool code.
The fence stays up
El Lago requires a four-foot fence around every pool at least 24 inches deep, with every gate self-closing and self-latching, and a spa needs the same permit and fence.

(281) 694-4352Draining and refilling a pool for replastering
El Lago's water comes from Harris County WCID No. 50, a district created in 1955 whose roughly 457 acres all lie in El Lago, Taylor Lake Village or Seabrook. Its drought plan, in force since August 23, 2024, counts filling or topping up a pool as recreational use. In Stage 1, new pools may be filled and existing pools topped up only once a week, during set hours, on Fridays for even-numbered addresses and public pools and on Saturdays for odd ones, and draining a pool onto hard surfaces is discouraged. In Stage 2, filling a new pool is prohibited and so is draining onto hard surfaces. In Stage 4, filling or topping up an existing pool is prohibited.
The plan doesn't say whether refilling an existing pool after a replaster counts as a fill or a top-up, and no current stage was posted when we read the district's pages on October 4, 2026, so ask the district before a drain date is set. It recommends reusing drained pool water, for example to irrigate landscaping.
Fill water from two directions
WCID 50 buys treated surface water from the City of Seabrook for customers east of Taylor Lake and from the Clear Lake City Water Authority for customers west of it. Both start as City of Houston Southeast Water Purification Plant water from Lakes Livingston, Conroe and Houston, and three backup wells reach the Gulf Coast Aquifer at about 600 feet. The water is chloraminated, at a 2025 average of 2.0 ppm, and the district's 2025 report prints no hardness figure. Water that is soft, meaning low in calcium hardness, pulls calcium out of the surface of fresh plaster, the National Plasterers Council warns, and the harm ranges from heavy discoloration to a weaker cement binder and a finish that wears out sooner. A test of the fill water comes first for that reason.
Ground and flood zones
At El Lago's Census centre point the USDA maps Verland soil mixed with urban land. Verland's subsoil reaches a linear extensibility of 6.8 percent, in the high class for shrink-swell, and the USDA rates it very limited for house foundations for that reason. The City's flood zones lie in the Armand Bayou and Clear Creek watersheds, which drain to Clear Lake and out to Galveston Bay, and since Hurricane Harvey the water district has cleaned and repaired storm drain pipes and proposed a multi-million-dollar project to enlarge the drainage system.

(281) 694-4352How a pool replaster goes on, from shell to fill
General practice, drawn from the plaster makers' and the Council's own instructions; your pool's own details come at the estimate.
Permit question and drain date
The Building Department answers the permit question, WCID 50's current stage sets the drain date, and the drained water goes where the plan allows.
Chip-out or bond coat, then the dig-outs
Loose plaster comes off. Where old plaster was cut back around a pipe or fitting, the Council wants that hollow filled level with the shell first, in a cement material that shrinks little or not at all, and left to cure, since extra finish thickness over a dig-out can discolor.
A cool, damp shell
SGM, a plaster maker, wants the shell cool and damp but not dripping when its finish goes on: standing water weakens the plaster in spots, and a hot, dry shell makes it set too fast, causing check cracking and delamination.
Scratch coat, then the finish coat
SGM's order puts a scratch coat on the deep-end bowl first, since it sets last and the crew has to walk on it, then the walls from the shady side toward the sunny side, then a finish coat over the whole pool troweled to 3/8 to 1/2 inch.
Hairline checks before the fill
The Council says every cement-based finish develops some shrinkage or check cracking before the pool is filled, meaning cracks that form during application or within 24 hours of final set, and that they typically reseal underwater as the cement keeps hydrating.
Fill and the first 28 days
NPT, a finish maker, says plaster starts hydrating as soon as it is mixed and 86 percent of the cement cures within the first 28 days, which is why the fill starts promptly and the start-up is followed closely.

(281) 694-4352Quartz, pebble and tile options alongside a replaster
White plaster is the classic finish, but a replaster can move up to quartz or pebble, and waterline tile and coping are often replaced in the same drain-down. Typical Houston-area figures for 2026, from one builder's baseline for a pool holding 12,000 to 18,000 gallons, start standard white plaster around $4,500 to $6,000, with quartz blends at $6,000 to $8,000 and pebble at $7,500 to $10,000, and the pool's size and the state of its shell shift those figures. Those are published figures, not prices from League City Pool Resurfacing.

(281) 694-4352El Lago pool replastering questions
Does an El Lago homeowners association have to approve a replaster?
Ask yours before the job is booked. The City lists three active homeowners associations: the El Lago Committee for the original section between NASA Road One and McNair Park, the El Lago Estates Civic Corps between McNair Park and the Taylorcrest neighborhood, and the Taylorcrest Community Association, each of which runs its own boat ramp. Its list of condominium and townhome associations includes the Lakeshore Condominium Complex, the Yacht Club Condominium Association, Marina Bay Condominiums and El Lago Point. The City says the HOAs are responsible for maintenance guidelines, so your association's own guidelines are the place to check.
Does El Lago have a public pool?
Yes. The City runs a pool and sprayground at the Community Center for members, with season memberships sold at City Hall or handed to the lifeguards during pool hours, and the pool can be booked for parties. Lifeguards, the manager and City staff enforce the City's pool rules.
