Sump Pump Installation & Repair in Scarborough

Your Basement’s Best Defence

For many Scarborough homeowners, a sump pump is not optional — it’s essential. The combination of clay-heavy soil, a high water table in some neighbourhoods, and increasingly intense rainfall events means groundwater regularly finds its way into basement foundations. A sump pump collects that water in a pit before it can spread across your basement floor and automatically pumps it safely away from the house.

Bluffs Plumbing Co. installs, repairs, and replaces sump pumps throughout Scarborough, and we’ll make sure your system is ready before the next heavy rain.

What to Expect

1. Call us — Tell us whether you’re dealing with a failed pump, a new installation, or an inspection before storm season. We’ll assess your situation and book an appropriate appointment.
2. Free estimate — We inspect the existing pump or sump pit, assess the discharge line, and give you a written quote. If a backup system makes sense for your home, we’ll explain the options.
3. We do the work — Installation or replacement is typically completed in a half day. New pit excavation takes longer. We route the discharge line away from your foundation and test the system under load before we leave.
4. Walkthrough — We demonstrate how to test the pump manually, explain what warning signs to watch for, and confirm the City subsidy documentation if applicable.

Pricing Transparency

Sump pump costs in Scarborough depend on whether you’re replacing an existing pump or starting from scratch:

• Pump replacement (existing pit): $800–$1,200 installed
• New installation (existing pit, new pump): $1,000–$1,500
• New pit excavation and pump: $2,000–$3,500
• Battery backup system addition: $600–$1,000
• City of Toronto subsidy: up to $1,750

Many homeowners combine a sump pump with a backwater valve for comprehensive flood protection — the two systems address different flooding risks and together provide significantly better coverage.

Understanding Sump Pump Failures

Power Outages During Storms The cruel irony of sump pump failures is that they most often happen during the exact conditions when you need the pump most: a major rainstorm that knocks out power. A battery backup system solves this problem. The backup unit is connected to a dedicated battery and activates automatically when the primary pump fails or loses power. For homes with any flooding history, a backup system is one of the wisest investments you can make.

Float Switch Problems Most sump pump failures aren’t mechanical — they’re float switch failures. The float switch is what tells the pump to turn on when water rises. If it gets stuck, tangled, or fails, the pump never activates. During our service calls, we always check the float switch operation alongside the pump itself.

Discharge Line Freezing Scarborough winters can cause sump pump discharge lines to freeze, particularly lines that run along exterior walls or discharge close to ground level. A frozen discharge line causes water to back up into the pit and potentially overflow. We can inspect your discharge line routing and recommend adjustments to reduce freeze risk.

Knowing When to Replace vs. Repair If your sump pump is older than 8–10 years and fails during a storm, repair often doesn’t make sense — the motor has already lived most of its useful life. Bluffs Plumbing Co. gives you an honest assessment: we’ll tell you when a repair is the right call and when replacement is the smarter investment.
