Sump pump installation, sized to your home.
Sump pits, pumps and battery backups sized for your home and water table, installed properly.
Signs you need a new sump pump
- No sump pump, or one older than 10 years
- Pump runs constantly, or never
- Power goes out during storms
- Water pooling around the pit or floor drain
New pit, replacement or backup?
| Job | When you need it | Typical cost |
|---|---|---|
| New sump pit and pump | No sump at all, and water at the floor or under the slab | $1,500 to $3,500 |
| Pump replacement | The pump is failing, noisy, or older than about 7 to 10 years | $500 to $1,400 |
| Battery backup | Power outages in storms, or a finished basement you can't risk | $800 to $1,800 |
| Water-powered backup | No batteries, but it connects to your water supply, so it needs a plumber and a backflow preventer. Not eligible for Halton's subsidy. | $800 to $1,500 |
Typical Hamilton-area ranges before tax. A dedicated circuit, a long discharge line or a deep pit add to the cost.
A new pit means cutting the basement floor, setting a sealed basin where water actually collects, connecting the weeping tile, and running the discharge outside. Read our guide to adding a sump pump for the full process.
Subsidies that can pay for it
Depending on where you live, a municipal program may pay for some or all of it. Halton Region covers 100% of disconnecting your weeping tile and installing a sump pump, up to $6,500, for homes in Burlington, Oakville and Milton. Hamilton's Protective Plumbing Program pays up to $2,000 plus the permit cost toward a new sump pump and pit installed with a backwater valve, when a City pre-qualified plumbing or drain contractor does the work, so ask whoever quotes it whether they're on the City's list.
Each program has rules about permits, licensed trades and timing, and Halton doesn't cover water-powered backups. Check our basement flooding subsidies guide before you book.
Where the water goes
A sump is only as good as its discharge. We route it well away from the foundation, add a check valve so water doesn't run back into the pit, and make sure the line won't dump water against your neighbour's house or freeze shut in January.
Weeping tile water belongs out of the sanitary sewer. Halton's subsidy requires weeping tile to be disconnected from the sewer, Brantford's requires it on sump projects, and Grimsby's proposed program would too. Disconnecting it is often exactly what a new sump does.

Install
Sealed pit, quality pump, check valve, discharge routed well away from the foundation.
- 03
Back it up
A battery backup so a storm outage doesn't flood you. We explain the water-powered option too, and when it doesn't qualify for a subsidy.
