A properly installed sump pump system is the single most effective defence against basement flooding from groundwater. If your Markham home has no sump pump, or has a pit but no reliable system in it, installation is one of the highest-value protection upgrades you can make — especially with the intense summer storms this region gets.
We install complete sump systems: the pit where needed, the pump sized to your home's groundwater conditions, the discharge line routed safely away from the foundation, and the check valve and fittings that make it all work quietly and reliably. The City of Markham's Private Plumbing Protection Rebate Program can help offset the cost of this work. Two things matter most: you must get pre-approval from the City's Environmental Services department before any work begins, and the work requires a permit and a City inspection. Rebate amounts change, so confirm current amounts with the City before you plan your budget.
Sump Pump Installation Around Markham
Many Markham homes built before the 1990s have weeping tile draining into the sanitary sewer and no sump pit at all — the norm for that era, and the reason the City's rebate program exists. Newer subdivisions usually have a pit roughed in, but we've seen plenty where the builder's pump failed years ago and was never replaced.
If you're planning to apply for the City's rebate, remember the sequence: pre-approval from Environmental Services comes first, then the permit, then the work, then the City inspection. Starting work before pre-approval disqualifies the application, so call us before anyone cuts concrete.
Signs You Need Sump Pump Installation
Your home likely needs a sump pump installation if:
- Your basement has flooded or taken on water. Water entry during storms or spring melt means groundwater is finding a way in. A sump system intercepts it before it reaches your floor.
- You have a sump pit but no working pump. Many homes have a pit roughed in by the builder but no pump, or a pump that died years ago and was never replaced.
- Dampness or efflorescence on basement walls. White mineral deposits and damp spots show that water is pressing against the foundation regularly.
- Your weeping tile drains to the sanitary sewer. Older Markham homes often have foundation drainage connected to the sanitary sewer — a flood risk and a candidate for disconnection with a sump pump.
- You're finishing the basement. Putting drywall and flooring over an unprotected foundation is a gamble. Install the protection first.
- Neighbours have flooded. Groundwater conditions are shared across a street. If homes around you have taken water, yours is at the same risk.
How We Do It
- 1
Assess your foundation drainage
We determine where water enters, whether weeping tile is present and where it drains, and the best location for the pit and discharge.
- 2
Discuss the rebate program
If your project qualifies for Markham's Private Plumbing Protection Rebate Program, we explain the process: pre-approval from Environmental Services must be in hand before work begins.
- 3
Permit and planning
Sump pump installation requires a permit and a City inspection. We plan the work around that process so everything is documented and approved.
- 4
Install the pit and pump
The pit is set at the right depth, the pump is sized for your conditions, and a sealed lid keeps odours and humidity out of the basement.
- 5
Run the discharge line
The discharge is routed to a proper outlet away from the foundation, with a check valve to prevent water flowing back.
- 6
City inspection and testing
The work is inspected as required, and we test the full system with water so you see it working before we leave.

Sump Pump Installation FAQs
Does Markham offer a rebate for sump pump installation?
Yes — the City's Private Plumbing Protection Rebate Program covers qualifying flood protection work, which can include sump pumps. The critical rules: you need pre-approval from Environmental Services before any work starts, and the work requires a permit and City inspection. Amounts change, so confirm current amounts with the City.
Do I need a permit to install a sump pump in Markham?
Yes. Sump pump installation requires a permit and a City inspection — and if you're applying for the rebate, both are part of the program requirements. We build the permit and inspection into the job.
Where does the discharged water go?
The discharge line carries water to a proper outlet on your property, away from the foundation, in line with City requirements. It must not drain to the sanitary sewer or onto a neighbour's property.
How long does installation take?
A straightforward installation where a pit already exists takes part of a day. Cutting a new pit into a concrete floor and running a new discharge line typically takes a full day, plus inspection scheduling.
Should I get a battery backup at the same time?
If your basement is finished or stores anything valuable, yes — it's far cheaper to add during installation than later. Storms that flood basements are the same storms that knock out power.
