Battery backup sump pump installed in Riverside South, what price range?

A sump pump with battery backup runs about $2,000 to $4,000 in published 2025–26 Ontario contractor pricing where an existing pit is already in place. If a new pit needs to be constructed, add the published range of about $500 to $1,500 for that work.

Ask what the quote assumes about the existing pit, the discharge line, and whether the primary pump is being replaced or kept.

A few things to confirm before the work starts. The City of Ottawa says a building permit is required to install a sump pump as a protective plumbing device, and the permit application must include floor plans and the device's location, type, make and model. Ask the contractor whether a licensed plumber does or signs off the plumbing part of the installation, since plumber is a compulsory trade in Ontario. The City's Residential Protective Plumbing Program offers a rebate of up to $1,500 for a primary or secondary sump pump with battery backup power installed in an existing pit, or up to $3,000 where a new pit is also constructed. The City rebates the lesser of that maximum or the actual cost of the work, the application must be received within 18 months of the permit's issue date (the City changed this from 12 months on July 1, 2026), and the program is listed as currently under review, so check ottawa.ca before relying on it. Rebates are not available for maintenance, repair or replacement of an existing protective plumbing device, so if your pump is already there and you are replacing it rather than adding to it, ask the City whether your job qualifies.

The most useful thing to have in writing before signing: the make and model of both the primary pump and the battery backup unit.
