When a pipe bursts in an Ottawa January, the best plumbers are licensed, insured, and on the way fast. Beyond emergencies, they handle drains, water heaters, fixtures, and rough-ins for renovations, and they know the local code and permit requirements. The companies below cover repairs, drain cleaning, water heater and sump pump replacement, and full renovation plumbing across the city. Each is a currently-operating Ottawa business with public reviews you can read, so you can confirm the licence, insurance, and pricing approach before a small leak becomes a flooded basement.

What separates a great plumber from a cheap quote, and the questions worth asking before you sign.
Plumbing is a licensed trade in Ontario. Ask for the licence number and confirm liability insurance before any work starts, especially for gas water heaters.
Some plumbers charge flat-rate per job, others by the hour plus parts. Ask which, and get any diagnostic or trip fee confirmed before they arrive.
Ottawa's spring melt tests every sump pump. Have yours checked, and ask about a battery backup so it keeps running through a power outage.
Before any emergency, have the plumber show you where the main water shutoff is. Knowing it can save your home from a burst-pipe flood.
