Louisville toilet repairs range from tank parts and wax seals in older downtown homes to adjustments on the newer fixtures in houses rebuilt after the 2021 Marshall Fire. Either way, most problems are fixed without replacing the toilet. Call the number on this page to be connected with a local plumber in Louisville.

What happens when you call
The number on this page connects you with an independent plumber who works in Louisville. Expect questions about what the toilet is doing, whether water has reached the floor or a ceiling below, and whether any other drain is slow or gurgling. If your home is one of the post-fire rebuilds, mention it; newer toilets can have different tank parts than older ones, and the plumber can bring the right kind.
At the house, the plumber typically checks the flapper, fill valve and flush valve first, then the supply line and shutoff, and finally the seal at the floor.
What affects the price
- Type of toilet: some newer dual-flush or pressure-assist models use specific parts.
- The fault: a tank part is quicker than lifting the toilet to replace the ring.
- Older fittings: in downtown homes, a worn flange or shutoff may need replacing.
- Floor condition: a slow leak may have reached the subfloor.
- Drain trouble: a clog past the toilet calls for more equipment.
- Timing: after-hours service costs more.
Louisville's housing and utilities
Louisville is a former coal-mining town in southeastern Boulder County that became a suburban community around its historic downtown and Main Street. The December 2021 Marshall Fire destroyed hundreds of homes, and the rebuilt houses have much newer plumbing. That leaves the city with an unusual mix: older homes near downtown whose toilets may sit on aging flanges, alongside rebuilt neighborhoods where fixtures are only a few years old and problems are more likely to be installation details or worn first-generation parts.
The city runs its own water and sewer utility. Water comes from South Boulder Creek, stored in Marshall Lake, Harper Lake or Louisville Reservoir, plus Colorado River basin water, treated at two city plants with chlorine. The report doesn't list hardness. Wastewater goes to the city's plant, built in 2017, on the east side of town. For sewer backups, Public Works Operations takes calls at (303) 335-4750 on weekdays until 3:30 p.m., and the on-call line is (303) 489-2301 after that. The city's Building Safety Division handles plumbing permits and inspections.
Before the plumber arrives
- Close the valve behind the toilet if it turns easily
- Locate the main shutoff in case you need it
- Keep from flushing a toilet that's backing up
- Note the toilet's brand if it's a newer model
- Clear space around the base
