Yes. Hamilton's Protective Plumbing Program pays up to $2,000 toward a backwater valve on a single family home with a basement, on City sewers, built before January 1, 2012. The full amount needs a City pre-qualified contractor; with any other contractor it is at most $500. A home adding a secondary dwelling unit cannot apply. JDT Construction is not on the City's list, so this page says where the list is.

## What does the grant cover?

The City “offers property owners of single-family residential homes a grant (subsidy) of up to $2000 for the installation of a backwater valve and other eligible works that help to reduce the risk of basement flooding.” Eligible work is a backwater valve with its assessment, disconnecting downspouts, and a sump pump installed with a backwater valve [(City of Hamilton, Protective Plumbing Program, read November 5, 2026)](https://www.hamilton.ca/home-neighbourhood/house-home/basement-flooding/protective-plumbing-program). A loan of up to $2,000 more is available where the work costs more than the grant.

**What Hamilton's Protective Plumbing Program pays**

| Item | Amount |
| --- | --- |
| Grant with a City pre-qualified contractor | Up to $2,000 |
| Grant with any other contractor (backwater valve) | Up to $500 |
| Loan where the work costs more than the grant | Up to $2,000 |
| City permit for a backwater valve on its own | $291 |

## Who qualifies?

All of these have to be true, in the City's list:

- “You own a single family residential home.”
- “Your home has a basement.”
- “Your home is connected to the City of Hamilton sewer system.”
- “Your property taxes are up to date.”
- “Your home was built before January 1, 2012.”
- “You are not currently in the process of adding a secondary dwelling unit.”

The City answers eligibility questions at 905-546-2489 [(City of Hamilton, Protective Plumbing Program, read November 5, 2026)](https://www.hamilton.ca/home-neighbourhood/house-home/basement-flooding/protective-plumbing-program).

## Why does the contractor matter?

Because the full grant depends on the City's list. The City: “Property owners who choose a contractor outside of the list will only be eligible for a maximum of $500 for the installation of a backwater valve.” The City's list has five pre-qualified contractors. JDT Construction Inc. is not one of them, so for this job on its own, the City's list is the way to the full $2,000.

## What permit does it need?

A building permit; the City notes “Backwater valve installations require building permit”, and its fee schedule sets a backwater valve on its own at $291 [(City of Hamilton, Building Permit Fees, read November 5, 2026)](https://www.hamilton.ca/build-invest-grow/construction-renovation/residential-building-renovation/building-permit-fees). On the program, the contractor gets the permit and the City inspects the work. When a backwater valve is part of a bigger job, like a basement [renovation](https://www.jdtconstruction.ca/builds/renovations/), it goes on that job's permit and plumbing inspections; see [the inspections on a build](https://www.jdtconstruction.ca/guides/inspections/). Adding a unit at the same time rules the grant out, which [money for an ADU in Hamilton](https://www.jdtconstruction.ca/guides/adu-grants/) covers.
