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.

Gaithersburg homes: what we see

Across Gaithersburg, we install everything from basic round-front models to one-piece and wall-hung toilets.

Most Gaithersburg 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

If the toilet is leaking, turn the shutoff valve behind it clockwise. If there's water on the floor around the base, don't use it — the wax seal may be broken.
