What Homeowners Say About DrainCom

The Sump Pump Services We Install and Repair

Open sump pit with a submersible pump, vertical float switch and twin PVC discharge lines during a sump pump installation

New Sump Pump Installation

Groundwater builds up in Mississauga basements during heavy rain and spring snowmelt. We install a reliable sump pump that clears water before it reaches your floor, so flooding stops being a worry every storm.

Sump Pump Replacement Service

An aging or failing pump lets you down at the worst possible moment. We swap out tired old units for modern, high-performance sump pumps built to run reliably for years.

Battery Backup Sump Pump Installation

Storms knock out power right when you need the pump most. A battery backup keeps your system running through an outage, so a blackout during a downpour doesn’t turn into a flooded basement.

Dual Sump Pump Installation

For extra peace of mind, we install dual systems with a primary and backup pump. If one pump quits or the rain really comes down, the second one takes over without missing a beat.

Sump Pump System with Weeping Tile

A pump works best tied into a healthy weeping tile system. We install complete drainage that collects groundwater and routes it away from your foundation, feeding the sump pit the way it should.

Sump Pump Plumbing and Discharge Line Installation

A good discharge line carries water well away from the house. We install and repair sump pump plumbing to improve drainage and stop water from circling right back into the pit.

Emergency Sump Pump Installation

If your pump dies mid-storm or the basement’s already taking on water, our team moves fast — often same-day — to install a replacement and get your protection back before the damage spreads.

Sump Pump Repair

Runs constantly, makes odd noises, or won’t clear the water? We inspect the system, find the fault, and complete the repair, whether it’s a stuck float switch or a worn-out motor.

Commercial Sump Pump Installation

We install sump pump systems for commercial buildings, warehouses, and multi-unit properties. Each one is designed for dependable groundwater management and long-term performance.

Sump Pump Maintenance Service

Routine service extends the life of your pump and heads off surprise failures. We inspect, clean, and test the system so it’s ready to work the day you actually need it.

What a Reliable Sump Pump Lets You Do

A dependable sump pump isn’t just insurance against a flood — it’s what makes the space downstairs usable and worry-free. Here’s what it protects and unlocks:

  • Finish the basement with confidence — build a family room, office, or gym knowing a storm won’t ruin it.
  • Add a rental or in-law suite — a dry basement is the foundation for a legal apartment where permitted.
  • Store without worry — keep furniture, documents, and seasonal gear safe from groundwater and mould.
  • Sleep through storms — a battery-backed system keeps working even when the power doesn’t.
  • Protect your foundation — clearing groundwater eases the pressure that cracks walls over time.
  • Sell with confidence — a documented flood-protection system and transferable warranty reassure buyers.

How Much Sump Pump Installation Cost in Mississauga

Sump pump installation cost comes down to the type of system, whether you need a new sump pit, and how involved the discharge plumbing is. Here’s a realistic price guide for Mississauga homeowners.

Service Price Range (CAD) Notes
Sump Pump Unit Only $900 – $1,200 Replacement only, no sump pit work required
Sump Pump + Tank (Complete System) $2,200 – $3,500 Includes sump pit, plumbing, and discharge line
Battery Backup Sump Pump $1,280 – $1,600+ Installed alongside an existing primary pump
Dual Sump Pump System $3,500 – $5,500+ Primary pump with battery backup system
New Sump Pit Installation $800 – $1,500 Includes excavation, sump basin, liner, and cover
Discharge Line Repair / Reroute $400 – $900 Code-compliant plumbing and discharge line
Commercial Sump Pump Installation Call for quote Sized for the building’s drainage requirements
 

These are approximate ranges for typical residential projects. You get a detailed written estimate after your free inspection, and the price you’re quoted is the price you pay.

💰 City Rebate Alert — up to $7,500: The City of Mississauga’s Basement Flooding Prevention Rebate Program covers a sump pump up to $6,000, with a total ceiling of $7,500 per property once you add measures like a storm-lateral backwater valve or weeping tile capping. A sanitary-lateral backwater valve may qualify for a separate Region of Peel rebate. Two things matter here: as of February 12, 2025, the City must pre-approve the work before it’s installed — skip that step and you lose the rebate — and the job has to be done by a licensed contractor. We’re licensed, we handle the pre-approval and the paperwork, and we keep your rebate protected from day one. Rebate amounts and rules change, so we confirm the current figures during your inspection. Details: mississauga.ca basement flooding prevention rebate.

What Affects Your Sump Pump Installation Cost

Every home drains differently, so the final number depends on the system and the work involved. We’ll walk you through it during your free inspection.

Installation type

 A brand-new system costs more than swapping out an existing unit.

Sump pit requirements

No pit yet? That means concrete cutting, excavation, and a new basin.

Pump capacity

Bigger homes or high groundwater call for a higher-capacity pump.

Discharge plumbing

Installing or rerouting the discharge line moves the total.

Battery backup

Adding a backup protects you through outages but raises the cost.

Additional drainage work

Tying into weeping tile or upgrading drainage adds labour and materials.

Why Mississauga Homes Need a Sump Pump

Plenty of Mississauga homes sit at real risk of basement flooding, thanks to our weather and the ground underneath. Mississauga sits on heavy Peel clay, with pockets of clay and shale near the Credit River and a high water table close to the Lake Ontario shoreline. That combination pushes water at your foundation harder than in many parts of Ontario.

  • Peel clay and shale — dense local soil holds water and pushes it hard against your foundation after rain.
  • Lake Ontario water table — homes closer to the shoreline deal with groundwater sitting high beneath the slab.
  • Heavy rainfall — intense storms saturate the ground and overwhelm home drainage fast.
  • Spring snowmelt — melting snow raises groundwater and the risk of seepage right along with it.
  • Hydrostatic pressure — trapped water forces moisture through cracks and weak points.
  • Older homes — many Mississauga homes were built before modern flood protection was standard.
  • Powerful storms — severe weather overwhelms drainage, and a pump clears water before it's a problem.

A properly installed sump pump is one of the most effective ways to cut your flood risk and protect the foundation from long-term water damage. The July 2024 storms that swamped basements across the GTA were a hard reminder of that — the City later opened its rebate program partly in response to that flooding.

Warning Signs You Need a New Sump Pump

A failing pump won’t protect you when the rain arrives. Spot any of these? Book an inspection before the next storm.

  • Runs constantly — a pump that never shuts off may be undersized, worn out, or fighting a drainage problem.
  • Strange noises — grinding, rattling, or heavy vibration usually means worn internal parts.
  • Frequent cycling — turning on and off repeatedly points to a faulty float switch or wrong sizing.
  • Rust or corrosion — visible corrosion drags down performance and shortens the pump’s life.
  • Basement flooding — water around the pit or on the floor means the system isn’t keeping up.
  • More than 10 years old — most pumps have a limited lifespan and get less reliable with age.
  • No battery backup — without one, the system sits dead during a storm-driven power outage.
  • Never been serviced — a pump that’s never been tested is a pump you can’t count on.

How We Install Your Sump Pump, Step by Step

Free inspection and site assessment

We check the basement, look over any existing pit, review the floor area, and confirm the best discharge route, along with your groundwater conditions.

Pump sizing

We use moisture detection tools, a drain camera when needed, and a close visual assessment to find exactly where the water is getting in. We never guess.

Sump pit installation (if required)

No pit? We cut the concrete, excavate to depth, set a durable basin, and backfill with clean gravel to improve drainage.

Sump pump installation

The pump goes in the pit and the float switch is set for proper operation. On dual systems, each pump is calibrated to trigger at a different water level.

Check valve installation

A check valve on the discharge pipe stops water flowing back into the pit after the pump shuts off, which cuts wasteful cycling.

Discharge line plumbing

We install or replace the discharge line, properly sloped and terminated to the Ontario Building Code, so water exits well away from the foundation.

Electrical connection

The pump connects to a dedicated GFCI-protected outlet. Battery backups are wired to their charger and tested.

Full system test

We fill the pit and test everything — pump activation, discharge flow, check valve, and backup functions.

Sump alarm installation

On request, we add an alarm that warns you when water rises above normal, giving you early notice if the pump ever falls behind.

Why a Professional Sump Pump Installation Pays Off

A sump pump does more than move water. Installed right, it protects the whole home.

  • Battery backup protection — keeps the basement covered when a storm cuts the power.
  • Eligible for municipal rebates — a sump pump can qualify for the City of Mississauga rebate (up to $6,000 toward the pump), and we manage the mandatory pre-approval so your rebate stays intact.
  • Works with interior and exterior waterproofing — the pump completes a full flood-protection system.
  • Removes groundwater — clears water from beneath the slab and eases hydrostatic pressure.
  • Protects your foundation — less standing water means fewer cracks, settlement, and structural damage.
  • Helps prevent basement flooding — reliable protection through heavy rain, snowmelt, and severe storms.

Frequently Asked Questions

 It depends on the system, whether you need a new sump pit, and the installation requirements. You get a free inspection and a detailed written estimate before any work begins.

Most installs are done in a single day. A new sump pit or more complex drainage work may take longer.

 It’s highly recommended. A backup keeps the pump running during the power outages that so often hit mid-storm, exactly when you need protection most.

 Most sump pumps last 7 to 10 years, depending on the unit, how often it runs, and regular maintenance.

 Yes. We swap old, damaged, or unreliable pumps for modern, high-performance systems that deliver dependable basement flood protection.

 It depends on your basement, groundwater levels, drainage system, and how much water your home collects. We size it correctly during the inspection.

Not always, but many Mississauga homes benefit from one because of heavy rainfall, Peel clay, and spring snowmelt. It’s protection in place before flooding ever becomes a problem.

 We recommend an inspection and test at least once a year, so it’s ready to work when you need it.

A properly installed pump clears groundwater before it reaches your basement. No system is bulletproof, but it dramatically lowers your flood risk.

 Yes. We provide emergency installation and replacement when your system fails or your basement is at immediate risk.

 Fast. We offer 24/7 emergency waterproofing service and work across Mississauga daily, so we can usually get a technician to you quickly, even on short notice.

We do, and it’s more important than most homeowners realize. The City of Mississauga rebate covers a sump pump up to $6,000 (up to $7,500 per property with other measures), but as of February 12, 2025 the work must be pre-approved before it’s installed — install first and you forfeit the rebate. We’re a licensed contractor, we handle the pre-approval and the paperwork, and we confirm the current amounts during your inspection.

Often, yes. The City allows a renewal rebate if your previous sump pump was installed 10 or more years ago. We’ll confirm your eligibility and manage the pre-approval as part of the job.

Worried About Flooding? Let's Talk

Don’t wait for the next storm to find out your pump can’t keep up. Our team will assess your basement, recommend the right system, and install it to protect your home year-round.
