$9,380 Subsidy for Flood-Resistant Garage Doors Offered by the City of Montréal

Do you live in Montréal and have a driveway that slopes downward toward your garage? Here’s some great news: Property owners in Montréal with below-grade garage entries can now benefit from a municipal subsidy of up to $9,380 through the RénoPlex Program for the installation of flood-resistant overhead garage doors. This initiative was validated through a pilot project involving the deployment of four AquaLOCK® flood doors in the Ville-Marie borough, confirming the system’s performance under urban flood conditions.

AquaLOCK® doors—widely implemented across Europe—offer robust flood mitigation by safeguarding vulnerable ingress points not only against surface runoff but also against more severe overland flood events. Engineered to withstand hydrostatic pressure, the doors provide certified protection against water ingress up to 1,190 mm in height for door openings measuring 2,100 mm (H) x 3,100 mm (W) and up to 500 mm for openings up to 5,000 mm wide.

Once secured, the AquaLOCK® system achieves 99.9% watertightness, significantly reducing flood risk while also enhancing physical security against unauthorized entry.

Code-Compliant Thermal Insulation

For enhanced thermal performance, a 40 mm rigid insulation panel may be installed on the door’s interior face, contributing to energy efficiency and improved indoor temperature control. This is especially advantageous in garages connected to conditioned spaces, such as basements with laundry facilities. The insulation also mitigates condensation and thermal bridging during the winter months.

Plumbing Scope Considerations

Depending on existing site conditions and the current plumbing infrastructure, installation may necessitate supplementary plumbing work to ensure full flood resilience. This may include the integration of backwater valves or sump systems. For project-specific requirements, consult Écohabitation’s resources or your local municipal code authority.

The RénoPlex subsidy also applies to standard entry doors (including residential front doors or basement-level access doors), with a funding allocation of up to $3,380 per qualifying installation. Full details, along with the pilot project video, are available on Écohabitation’s designated project page.

Pilot Project Outcomes in Montreal

An estimated 80,000 properties in Montreal feature reverse-sloped driveways, making them highly susceptible to urban flooding—particularly in topographical depressions. With climate-induced weather events becoming increasingly frequent and severe, flood mitigation has become a critical infrastructure priority.

 

The pilot project aimed to validate the technical viability and performance standards of AquaLOCK® flood doors in Montréal’s urban context. Four adjacent homeowners, each meeting eligibility requirements, replaced their existing doors with the AquaLOCK® system and completed plumbing retrofits as needed. Controlled flooding simulations were then conducted to assess system integrity and watertight performance under real-world flood scenarios.
