Siding Installation Licensing in Quebec

Siding installation in Quebec requires contractors to hold the appropriate RBQ licence for construction work. On regulated construction sites, workers may need a CCQ competency certificate. Building permits may be required for re-siding, especially if existing siding is being removed. The Quebec Construction Code specifies requirements for moisture barriers, air barriers, and insulation behind siding. CNESST safety regulations apply for working at heights.

Ask for the contractor's RBQ licence number and verify it on the online Licence Holders' Registry.

(1) Installs siding over old damaged siding without addressing underlying rot or moisture issues (2) Skips housewrap or moisture barrier installation (3) No proper flashing around windows and doors - leading cause of water infiltration (4) No WSIB coverage for workers at height on scaffolding

(1) Will you remove the old siding and inspect the sheathing underneath? (2) What moisture barrier and flashing details are included? (3) Do you carry liability insurance and WSIB coverage? (4) What siding brand do you recommend, and what is the manufacturer warranty? (5) What is your workmanship warranty, and does it cover issues like buckling or warping?

While not legally required, it is strongly recommended that siding installations carry liability insurance. Ask for proof of coverage before hiring.
