Sump pump installation that keeps up.
A pump sized for code minimums will not keep up with clay soil in a spring storm. We size for the ground you actually have.


Sump systems we install and rescue.
Most of the pumps we replace failed because something behind them was already failing. We check the whole system first.

New Sump Pit & Pump
Where none exists
Breaking the slab, excavating and setting the liner, connecting the weeping tile, and routing the discharge. Generally a full day.
Pump Replacement & Upgrade
Into a sound existing pit
Most pumps last seven to ten years, and less on clay where they cycle constantly. A straight swap into a good pit takes a few hours.
Battery Backup Systems
For when the power goes
The storm that needs the pump is the storm that cuts the power. A primary pump alone is a system that fails exactly when it matters.
Discharge Line Routing
Away from the foundation
A line emptying beside the house recirculates the same water and runs the pump continuously. On tight lots this is the hard part.
High-Water Alarms
Warning before the flood
A float sensor that sounds when the pit rises above where the pump should have cleared it, while there is still time to act.
Whole-System Assessment
Pit, tile, grading, pump
Often the pump is fine and the pit is undersized, the weeping tile is silted, or the grading is feeding it. We look before selling one.
Pump running constantly, or silent in a full pit? We respond across the GTA around the clock.

Written assessment first
Sized for the soil
Slow-draining clay across Peel and York delivers water to the pit faster than a minimum-spec pump can eject it.
Battery backup as standard
The night a pump is needed most is the night the power goes out. A pump without backup is a pump that fails on cue.
Discharge routed properly
A discharge line that empties beside the house returns the same water to the pit. We route it to somewhere it can go.

Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

Sump pump questions.
A new pit, pump, discharge line, and battery backup runs $1,500 to $3,500 installed. Swapping a pump into a sound existing pit is usually $600 to $1,500. The difference is the pit and the plumbing rather than the pump.
The night a pump matters most is frequently the night the power goes out, because the same storm causes both. On any property where flooding means finished space, we treat backup as part of the system rather than an extra.
Seven to ten years, and properties on slow-draining clay through Peel and York sit at the shorter end because the pump cycles far more often. A pump working through every spring melt wears out on that schedule.
No. Toronto and the surrounding municipalities prohibit connecting a sump discharge to the sanitary sewer, because it overloads the system during exactly the storms that need capacity. It goes to grade or to a storm connection.
For a new pit, yes, a section of slab comes out to excavate and set the liner, and we patch it afterwards. If a sound pit already exists, no slab work is needed. We establish which before you commit.
What GTA Homeowners Ask About Sump Pumps.
From sizing for clay soil to battery backup, answered by the crews who install and replace them.
A new pit, pump, discharge line, and battery backup runs $1,500 to $3,500 installed across the GTA. Swapping a pump into an existing, properly built pit is considerably less, usually $600 to $1,500. The gap is the pit and the plumbing rather than the pump itself.
Far cheaper, and it solves a different problem. Waterproofing stops water reaching the foundation; a sump ejects water that has already arrived at the weeping tile. Interior waterproofing runs $100 to $250 per linear foot against $1,500 to $3,500 for a sump system. They are complements rather than alternatives.
Only with a specific endorsement. Standard Ontario home policies exclude water backup and sump failure by default, and the coverage is sold as an add-on that many owners do not realise they lack until a claim is refused. It is worth checking your policy before the next spring melt rather than after it.
It depends on how fast water reaches the pit, not on the size of the house. On the slow-draining clay through Peel and York, a sustained storm delivers water faster than a code-minimum pump was ever specified to eject, which is why so many of the pumps we replace were technically compliant and still overwhelmed.
- How much does sump pump installation cost in Toronto?
- A new pit, pump, discharge line, and battery backup runs $1,500 to $3,500 installed across the GTA. Swapping a pump into an existing, properly built pit is considerably less, usually $600 to $1,500. The gap is the pit and the plumbing rather than the pump itself.
- Is a sump pump cheaper than waterproofing a basement?
- Far cheaper, and it solves a different problem. Waterproofing stops water reaching the foundation; a sump ejects water that has already arrived at the weeping tile. Interior waterproofing runs $100 to $250 per linear foot against $1,500 to $3,500 for a sump system. They are complements rather than alternatives.
- Does home insurance cover sump pump failure in Ontario?
- Only with a specific endorsement. Standard Ontario home policies exclude water backup and sump failure by default, and the coverage is sold as an add-on that many owners do not realise they lack until a claim is refused. It is worth checking your policy before the next spring melt rather than after it.
- What size sump pump does my Toronto basement need?
- It depends on how fast water reaches the pit, not on the size of the house. On the slow-draining clay through Peel and York, a sustained storm delivers water faster than a code-minimum pump was ever specified to eject, which is why so many of the pumps we replace were technically compliant and still overwhelmed.
- Do I actually need a sump pump, or is my basement fine?
- If your foundation has weeping tile, a sump is usually the other half of that system, since the tile has to discharge somewhere. Older homes built without weeping tile sometimes have no pit at all. We check what drainage already exists before recommending a pump, because installing one where nothing feeds it achieves nothing.
- Pedestal or submersible pump for a Toronto home?
- Submersible pumps sit in the pit, run quieter, and handle more volume, which suits the duty cycle on clay soil. Pedestal pumps sit above the pit, cost less, and are easier to service, but they move less water and are noticeably louder in a finished basement. We specify submersible for most GTA installs.
- Do I need a battery backup sump pump in Toronto?
- The night a pump matters most is frequently the night the power goes out, because the same storm does both. A primary pump without backup is a system that fails at precisely the moment it is needed. On any property where a flooded basement means finished space, we treat backup as part of the install rather than an upgrade.
- How long does a sump pump battery backup run during an outage?
- A typical deep-cycle battery carries a backup pump through several hours of intermittent cycling, and considerably less if the pit is filling continuously. That is usually enough for a summer storm outage. It is not enough for a multi-day winter outage, which is where a generator connection becomes the better answer.
- What is a high-water alarm and is it worth having?
- It is a float sensor that sounds when water in the pit rises above the level the pump should have cleared. It costs very little and it tells you the system is failing while there is still time to act, rather than after the water reaches the slab. On a finished basement it is among the cheapest protection available.
- How long does a sump pump last in a Toronto basement?
- Seven to ten years is the normal range, and properties on slow-draining clay sit at the shorter end because the pump cycles far more often. A pump that runs through every spring melt and every heavy storm is doing several times the work of one in a dry-lot home, and it wears out on that schedule.
- How do I know if my sump pump is failing?
- Watch for cycling that runs longer than it used to, a pump that hums without moving water, visible rust or debris in the pit, and any change in the sound it makes. The most common silent failure is a float switch that has stuck, which leaves a working pump sitting in a full pit doing nothing.
- How often should a sump pump be tested?
- Twice a year is sensible, before the spring melt and before the autumn storms. Pour a bucket of water into the pit and confirm the pump starts, moves water, and shuts off cleanly. If it does not start, you have found that out in March rather than during the storm that would have flooded the basement.
- My sump pit was full but the pump was silent. What happened?
- If the basement flooded during a storm and the pit was full with no sound from the pump, the pump did not fail, the power did. That is the single most common flooding scenario we attend, and it is entirely preventable with a battery backup that costs a fraction of the interior repairs that follow.
- How long does a sump pump installation take?
- A straight pump replacement into a sound existing pit is a few hours. A new installation, which means breaking the slab, excavating and setting the pit, connecting the weeping tile, and routing the discharge, is generally a full day. We give you the realistic figure before starting rather than partway through.
- Where does the sump pump discharge line go?
- Far enough from the foundation that the water cannot return to the pit, and to somewhere it can actually drain. A discharge that empties beside the house recirculates the same water and runs the pump continuously. On tight urban lots that routing is the hardest part of the job and the part most often done badly.
- Can a sump pump discharge into the sanitary sewer in Toronto?
- No. Toronto and the surrounding municipalities prohibit connecting a sump discharge to the sanitary sewer, because it overloads the system during exactly the storms it needs capacity for. Discharge must go to grade or to a storm connection where one exists, and we route accordingly.
- Will installing a sump pump mean breaking up my basement floor?
- For a new pit, yes, a section of slab has to come out to excavate and set the liner, and we patch it afterwards. If a pit already exists and is sound, no slab work is needed at all. We establish which situation you are in during the assessment so the disruption is known before you commit.
