Toilet repair and installation

A toilet that runs all night, rocks on the floor or clogs every week usually has a clear cause. We find it, then tell you whether a repair will do or a new toilet makes more sense.

Does this sound familiar?

  • The toilet keeps running or refills on its own
  • Water shows up around the base after a flush
  • It clogs often or the flush has gone weak
  • The bowl or tank has a visible crack
  • The toilet rocks when you sit on it

Repair it or replace it?

A running toilet is often a worn flapper or a fill valve that no longer shuts off. Those are repairs. A cracked bowl or tank is different, because cracked porcelain can leak or give way.

Replacement also makes sense when a toilet keeps running after repairs, clogs again and again, or flushes weakly for no reason we can find. We explain what we found and what each option involves before you decide.

Check for a hidden tank leak

Put a few drops of food colouring in the tank and leave the toilet alone for a while. If colour reaches the bowl without a flush, water is leaking through. It wastes water all day, even when nothing looks wrong.

When it is more than the toilet

If one toilet is clogged, the problem is usually in that toilet or just past it. If other fixtures are slow too, or water comes up a basement floor drain when you flush, the shared line may be blocked. Stop using water and see drain cleaning or sewage backup.

This page covers toilet installation and toilet repair.

We serve homes in Etobicoke, Mississauga, North York and nearby Toronto communities.
