Garland’s tap water is hard, and most of its housing is old enough for that hardness to have had decades to work on the grout. The city buys treated water from the North Texas Municipal Water District, which it helped found in 1951, and Garland reports hardness averaging about 161 mg/L — roughly 7 to 10.5 grains per gallon. That is noticeably harder than water in many neighboring cities, and it lands on homes built during one of the fastest growth spurts in DFW history: Garland’s population went from 10,571 in 1950 to about 38,500 in 1960 and 81,437 by 1970. The result is a city full of 50- to 70-year-old tile that has been exposed to mineral-heavy water its whole life.
The short answer: most Garland homes should have tile and grout professionally cleaned every 12 months — a little sooner than the typical 12–18 month DFW baseline — because hard water leaves mineral film on shower tile and glass quickly, and older grout is porous enough to hold that film. Sealing after cleaning matters more here than in softer-water cities.
Key Takeaways
- Garland buys treated water from the North Texas Municipal Water District, whose sources include Lavon Lake, Lake Chapman, Lake Tawakoni, Lake Texoma, and Bois d’Arc Lake.
- The city reports hardness averaging about 161 mg/L (7.0–10.5 grains per gallon), which is classified as hard.
- Population grew from 10,571 (1950) to about 38,500 (1960) to 81,437 (1970), so much of Garland’s housing is 1950s–1970s construction with aging grout.
- Downtown Garland, around the historic square and the Plaza Theatre, holds older commercial buildings, while Firewheel Town Center is a nearly one-million-square-foot open-air shopping district with heavy commercial tile traffic.
- Standard interval: about every 12 months for homes; quarterly for restaurants and retail entry tile.
Why Garland’s Water Is Harder on Grout
Garland became one of the original member cities of the North Texas Municipal Water District in 1951, and the city began drawing from Lake Lavon after a serious drought between 1950 and 1954 strained the well water it had relied on. Today’s supply blends several NTMWD lakes, and the city’s own figures put average hardness around 161 mg/L. In practical terms, that means white scale on shower doors and faucets within weeks, and a chalky film across shower and tub tile that settles into grout lines. Once minerals bond with soap residue in porous grout, ordinary household sprays won’t lift them — hot-water extraction with a hand-brushed grout pass and a descaling step will.
The Boom Years: 1950s–1970s Homes and 60-Year-Old Grout
Garland shifted from a farm-and-mill town to a Dallas suburb after World War II, helped by industrial employers like the Byer-Rolnick hat factory (the Resistol brand) and the wartime aircraft plants that came before. Its population nearly quadrupled in the 1950s and roughly doubled again in the 1960s, and the homes built to house those workers are now well into their sixth or seventh decade. Original ceramic bathroom tile, cement-based grout, and worn sealers are common. In those homes, cleaning is less about surface dirt and more about lifting years of embedded soil and mineral buildup, then re-sealing joints that have lost their protection entirely.
Historic Downtown and Firewheel: Two Kinds of Commercial Tile
Garland’s downtown square has a long history of rebuilding — the Plaza Theatre building started life as a hardware store in 1918 before it burned and was reconstructed as a theater in 1941, and the Santa Fe Depot dates to 1901. Older downtown storefronts often combine original floors with decades of renovations, and they benefit from gentler methods. Across town, Firewheel Town Center, a nearly one-million-square-foot open-air shopping and dining center at the President George Bush Turnpike and State Highway 78, generates the opposite need: constant traffic across restaurant and retail entry tile that stays cleaner on a quarterly schedule, like the hospitality work we do throughout DFW’s tile and grout cleaning service area.

Frequently Asked Questions
Is Garland’s water hard?
Yes. The city reports average hardness around 161 mg/L, about 7.0 to 10.5 grains per gallon, which is classified as hard. It comes from the North Texas Municipal Water District.
How often should Garland homes have tile and grout cleaned?
About once a year is a good rule, slightly more often than the usual 12–18 months elsewhere in DFW, because hard water builds mineral film quickly on shower tile and in porous grout.
Why does grout in older Garland homes stain so easily?
Much of Garland was built between 1950 and 1970, and grout that age is porous and often unsealed. Soil and mineral scale soak into the joint, so it needs hot-water extraction and hand-brushing rather than a surface cleaner, followed by a fresh sealer.
Do Garland restaurants and retail spaces need a different schedule?
Yes. High-traffic entry tile in restaurants and retail centers such as Firewheel Town Center holds up best with quarterly professional cleaning.
