Fiberglass Pool Resurfacing in Weir, Texas

Fiberglass pools in a town of 232 homes

Weir is small. The 2020 Census counted 699 residents and 232 housing units, and the Census Bureau's estimate for July 1, 2025 is 792. Its housing splits two ways in the Bureau's 2020–2024 survey: 50 of an estimated 154 units, about a third, went up in the 2010s, while 63, about 40.9%, date from before 1990, and the median home was built in 1995. Of those units, 85 are single-family detached houses and 69, about 44.8%, are mobile homes. The sample is very small, so every one of these shares is rough.

Williamson County's subdivision records show these recorded subdivisions inside the city limits: East Weir, the oldest, along with Country East Estates and its Section 2, Country Creme Estates, Katy Meadow, Meadowlarke Acres, the Leiv Subdivision, Weir Blocks 9, 10, 11 and 12, one recorded simply as Weir, and the one-lot C M Walker Subdivision of May 17, 2012.

The homes from the 2010s are 7 to 16 years old in 2026. Makers disagree on when fiberglass starts to show its age: River Pools says a pool is usually 20 or 30 years old before it needs refinishing, while ecoFINISH, which sells a refinishing coating, puts the first signs of wear at 10 to 15 years of regular use. The Census doesn't count pools, so a house's age only hints at its pool's.

Stains, scale and wear on gelcoat

Not every mark on a shell calls for a refinish. Tallman Pools, a fiberglass pool maker, sorts stains into organic ones, green, brown or tan from berries, dirt, pollen or algae, and metal ones: orange, brown or tan from iron, green, blue or teal from copper, and brown, black or purple from manganese. White scale comes in two kinds. Calcium carbonate foams under a drop of muriatic acid; calcium silicate shows no reaction and is best left to a fiberglass technician. Tallman says to use only stain removers made for fiberglass, and never to sand, polish or buff the gelcoat unless a fiberglass professional says to. A shell that has turned chalky and rough all over is the wear ecoFINISH describes as the gelcoat breaking down, and that is the point where resurfacing comes in.

Draining a fiberglass shell without lifting it

Groundwater is the risk. River Pools explains that water in the soil around a pool pushes up on the shell, and that with too little water inside, the shell can bulge, crack or even float. It adds that sand backfill can liquefy when it is saturated and press against the walls, which is why it recommends gravel. Tallman Pools warns that too much hydrostatic pressure can shift a shell, bulge it or make it fail, and it wants its written authorization before one of its pools is drained.

Weir sits mostly on Blackland Prairie clays. By our measure of the USDA's Williamson County soil survey, four soils mapped on 1 to 3 percent slopes cover most of the city: Austin silty clay 32.4% of the area, including the Census center point, Castephen silty clay 19.0%, Houston Black clay 9.7% and Krum silty clay 8.2%, with frequently flooded Oakalla and Tinn soils along the drainages. The survey rates the Austin and Castephen soils well drained, over soft bedrock typically about 29 and 16 inches down, and Houston Black, a clay that swells and shrinks a lot, moderately well drained. It maps at county scale, so it doesn't replace a check at the lot itself.

None of the 16 ordinances on the City of Weir's ordinance page is titled for stormwater, drainage, nuisances or swimming pools, and no City rule on draining a pool has turned up. The State's rules still cover the water: the Texas Commission on Environmental Quality counts pool drain water as alternative onsite water that an owner may reuse, for landscape irrigation for example, without its authorization. It may not be reused within five days of a shock or acid treatment, and it may not pond or run off across a property line or onto pavement.

A railroad stop named for an 1850s pioneer

The Handbook of Texas says Weir was founded around 1900 as a station on the railroad between Georgetown and Granger and named for Calvin Weir, a pioneer in the area in the 1850s, whose son Horace became the first postmaster. Residents of nearby Townsville moved in, and Townsville's post office followed in 1903, the year East Weir was platted with 42 lots, according to the County's records; part of it was replatted on November 14, 1905. Weir reached a peak of 300 people in 1930, fell to 100 by 1968, incorporated in 1987 and counted 591 in 2000. It is still growing at the edges: the Census Bureau's figure for its land area rose from 1.627 square miles in 2020 to 1.821 in 2025, and the City's ordinance list includes annexations adopted in September 2021 and March 2022.
