Sump pumps don't last forever, and they rarely fail at a convenient time. If your pump is past its prime, running rough or has already failed once, planned replacement is far better than the emergency version — you choose the timing, the equipment and the level of backup protection, instead of taking whatever can be installed during a storm.
We replace sump pumps across Markham with quality equipment sized to your home's actual conditions. The pit, discharge line and check valve are all inspected as part of the job, because a new pump on a failed check valve is no upgrade at all.
Sump Pump Replacement Around Markham
Builder-grade pumps in Markham's 1990s and 2000s subdivisions are reaching the end of their lives in waves — whole streets in Cornell, Wismer and Berczy Village have pumps of the same age wearing out together. If yours is original and your basement is now finished, the replacement conversation is overdue.
Replacement is also the cheapest moment to add a battery backup, since the pit and discharge are already being worked on. Most of the backup systems we install go in during a pump replacement visit.
Signs You Need Sump Pump Replacement
It's time to plan a replacement when:
- The pump is seven to ten years old. That's the typical service life. A pump this age hasn't necessarily failed — it's living on borrowed time.
- It has failed or needed repair already. A pump that has been repaired once is telling you its components are wearing. Replacement ends the cycle.
- It runs louder or rougher than it used to. Worn bearings and impellers get noisier as they degrade. Noise is the pump's early warning system.
- It struggles during heavy rain. A pump that falls behind during storms is either worn or undersized. Either way, your basement is at risk exactly when it matters.
- You've finished the basement since the pump went in. The stakes are higher now. A basic builder-grade pump protecting a finished basement deserves an upgrade, ideally with backup.
- Visible rust or corrosion. Corrosion on the pump body or fittings means failure is a matter of when, not if.
How We Do It
- 1
Inspect the existing system
We assess the pump, pit, check valve, float and discharge line to see what can stay and what should go.
- 2
Recommend the right replacement
Pump capacity is matched to your pit's inflow rate and your basement's risk level — not just swapped like-for-like by default.
- 3
Quote clearly
You get the price for the pump and any related work — check valve, discharge repairs, backup system — before anything is removed.
- 4
Remove and replace
The old pump comes out, the pit is cleaned of sediment, and the new pump is set and connected with a new check valve.
- 5
Test the full cycle
We fill the pit and watch the pump start, pump and shut off correctly, and confirm the discharge line flows freely.
- 6
Discuss backup protection
If your basement is finished, we'll quote a battery backup alongside — the replacement visit is the cheapest time to add one.

Sump Pump Replacement FAQs
How long does a sump pump replacement take?
A straightforward replacement usually takes one to two hours, including pit cleaning and testing. If the discharge line or check valve needs work, plan for a bit longer.
Should I upgrade to a bigger pump while I'm at it?
Only if your conditions call for it. We measure how fast water enters your pit during wet conditions and size accordingly. An oversized pump short-cycles and wears out faster, so bigger is not automatically better.
What's the difference between pedestal and submersible pumps?
Submersible pumps sit in the pit, run quieter and handle higher volumes — they're what we install in most homes. Pedestal pumps sit above the pit and are easier to service but louder and less powerful.
Can I add a battery backup during replacement?
Yes, and it's the ideal time. The backup system shares the pit and discharge, so installing both together saves a return visit. If your basement is finished, we strongly recommend it.
Do I need a permit to replace a sump pump?
A like-for-like pump replacement generally doesn't require a permit, but new installations and changes to drainage connections do. If your project involves the City's rebate program, permit and inspection requirements apply — we'll confirm what your job needs.
