Replacing a toilet in Cabin John is one of the best small upgrades you can make — better flushing, less water, and a more comfortable height. We handle removal, install, and haul-away.

Signs it's time to replace your toilet
- Old 3.5+ gallon-per-flush model
- You want a comfort-height or elongated bowl
- Cracks in the bowl or tank (even hairline)
- Frequent clogs despite normal use
- Toilet rocks or leaks at the floor
- Constant repairs to the flush mechanism
What's included
Shut off and drain, remove the old toilet, inspect the flange and subfloor, new wax ring (or wax-free seal), new closet bolts, new braided supply line and quarter-turn shutoff if needed, install and level the new toilet, caulk the base, and haul away the old one.
Cabin John homes: what we see
Older Cabin John homes often have cast-iron flanges and 10" or 14" rough-ins. We measure before you buy so the new toilet fits.
Most Cabin John homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program.
The flange is the hidden piece
A broken or low flange is the most common reason a toilet leaks at the base or rocks. We check it every time and repair it with a spacer or repair ring, or replace it when needed — before the new toilet goes in.
Choosing a toilet
WaterSense-labeled toilets use 1.28 gallons per flush or less and still flush well. Comfort height (about 17") is easier on knees and a favorite with older homeowners. Measure the rough-in distance (wall to bolt center) — most are 12", but older homes sometimes have 10" or 14".

Until we arrive
