A toilet that runs all night, rocks on the floor, or overflows into the bath is a small fixture with a messy bill. Underwood repairs and installs toilets across Collin, Grayson, Fannin, Hunt, and Lamar counties from offices in McKinney, Bonham, and Sherman.
Shut the valve on the wall behind the tank if you can, then call. We’ll get a plumber on the schedule, evenings included.
Call or request a quote: Tell us if it’s running, leaking at the base, or backing up. We pick up nights and evenings.
Find the cause: Fill valve, flapper, wax ring, flange, or a clog past the bowl. We don’t guess and sell a new toilet first.
Explain the options: A rebuild, a flange repair, or a new toilet. You hear the difference before any work starts.
Fix it in one trip: Vans carry the common fill valves, flappers, wax rings, and supply lines, so most toilet repairs finish on the first visit.
Test the flush: We fill the tank, flush more than once, and check the base and the supply for leaks.
Leave it clean: The bath floor gets wiped down before we head out.
Repairs, flange and wax-ring replacement, supply lines, and full toilet installs. If the clog is past the bowl, we treat it as a drain, not a flapper problem.
Not always. A running tank is often a fill valve or flapper. We’ll say so if a rebuild is the cheaper fix, and we’ll say so if the bowl or the flange is done.
McKinney, Allen, Prosper, Sherman, Denison, Bonham, Greenville, Paris, and the towns between, out of four offices in McKinney, Bonham, and Sherman.
Same-week scheduling on routine installs, and evenings when a toilet is the only one in the house. Call (903) 449-1677 and we’ll put a plumber on the schedule.
Yes, on larger installs, subject to credit approval. Ask the plumber or see the Financing page.
Why Underwood
01
You get a person, not a queue. Nights and evenings included, we pick up and tell you when the plumber is actually coming.
02
The parts for a running tank and a leaking base ride on the van, so a toilet repair usually ends on that visit.
03
If the toilet is backing up because of the line or the tank in the yard, we handle that too. One company, not a second call.
04
State-board licensed plumbers, TCEQ registered, with years of fixture work across DFW and Northeast Texas.
What We Fix
We set and repair toilets for homes in McKinney, Allen, Prosper, Sherman, Denison, Bonham, Greenville, Paris, and the towns in between.

I needed a sewer tank cover replaced due to it being hit by the lawnmower. These guy fixed it in less than 30 minutes. Chad also suggested putting landscaping stuff around the 4 tanks to prevent this happening again. Totally happy with their service.![]()
