Celina’s Historic Downtown Square dates to the early 1910s, its brick storefronts still anchoring Friday Night Markets and Christmas on the Square today. But almost everything around that square is new. Celina’s population was 16,739 at the 2020 census; by 2025 it had reached roughly 64,427, a jump of more than 143 percent in five years that made it the fastest-growing city in the country among places over 20,000 residents. Master-planned communities like Light Farms and Mustang Lakes have added thousands of homes in that span, which means most Celina households are living on tile that’s only a year or two old — brand-new, but rarely sealed the way it should be.
Short answer: new-build tile in Celina should get its first professional clean-and-seal within the first 12 to 18 months, not “eventually.” Production and custom builders almost never seal grout as part of construction, so light designer grout starts absorbing dirt and graying from day one unless a homeowner seals it separately.
Key Takeaways
- Celina’s Historic Downtown Square dates to the early 1910s and remains the city’s original core.
- Population grew from 16,739 in 2020 to roughly 64,427 in 2025, a 143-plus percent increase.
- Celina was ranked the fastest-growing U.S. city over 20,000 residents from mid-2024 to mid-2025.
- Light Farms and Mustang Lakes are among the master-planned communities driving that growth.
- Almost none of that new construction includes grout sealing as a standard builder step.
A Small Historic Core in a Sea of New Construction
The Downtown Square’s early-1900s buildings, including a former newspaper office now serving as a local history museum, are some of the oldest structures in Celina. Tile inside businesses and homes right around the square has had decades to age and, where it’s original, deserves gentle, low-pressure cleaning rather than aggressive scrubbing. But that core is a small fraction of the city today. The overwhelming majority of Celina’s housing stock — and its tile — has gone in within the last five to ten years as the population has quadrupled.
New-Build Grout: Sealed Late Is Better Than Never
Builders in fast-growing subdivisions are working on tight schedules, and grout sealing is one of the first finishing steps that gets skipped. Left unsealed, light-colored designer grout — a common choice in Light Farms and Mustang Lakes-era homes — starts absorbing everyday dirt and cooking residue almost immediately, and within a year or two it can look noticeably grayer than the day it was installed. The fix isn’t complicated: a professional clean-and-seal in the first year or two resets the grout to its original color and protects it going forward, and it’s far cheaper than trying to strip years of embedded staining out of unsealed grout later.

Frequently Asked Questions
Why does new tile in Celina already look dingy after a year?
Most new-construction grout is never sealed by the builder. Unsealed grout, especially light designer colors, absorbs dirt and moisture from day one and can look visibly grayer within 12 to 18 months of move-in.
Is Celina’s rapid growth actually as fast as it sounds?
Yes. The city’s population grew from 16,739 at the 2020 census to an estimated 64,427 by 2025, an increase of more than 143 percent, and it was ranked the fastest-growing U.S. city over 20,000 people from mid-2024 to mid-2025.
Does Celina have any older tile worth preserving?
A small amount, concentrated around the Historic Downtown Square, which dates to the early 1910s. That older tile is a small share of the city’s total housing stock compared with the past decade’s new construction.
How soon after move-in should new tile be sealed?
Within the first 12 to 18 months is ideal. Sealing early protects the grout before everyday dirt and cooking residue have a chance to set in permanently.
