What’s specific to Gatineau windows

Gatineau's winters make triple glazing worth pricing, and ENERGY STAR is the threshold both for Rénoclimat's per-opening assistance and for a quote worth comparing. Québec makes much of the country's windows, which keeps local prices competitive against Ottawa-side quotes, and the tax and licence differences are the same as for any Gatineau job: GST + QST rather than HST, and an RBQ licence for the installer. Visible changes in the Hull heritage areas get a review.

• The same job quoted across the river is taxed differently: 13 % HST in Ottawa against 14.975 % GST + QST in Gatineau, about $200 more per $10,000 on the Québec side. A contractor working in Gatineau also needs an RBQ licence, which an Ontario-only contractor may not hold. Agence du revenu du Canada (taux TVH) et Revenu Québec (TPS + TVQ)

Permits and rules in Gatineau

• In Gatineau, work under $26,000 on an existing building generally needs no permit, except anything touching the foundation, the structure or interior walls, which always does. Above that amount a building permit applies. The URBAIN assistant on gatineau.ca tells you which case you are in. Ville de Gatineau
• Gatineau does not commit to a processing time: it depends on the type of request and the volume of files in progress, and the clock starts only once the file is complete and the fees are paid. Ville de Gatineau
• A contractor doing renovation work for a client in Québec must hold an RBQ licence in the relevant subcategory, whatever the size of the job. Only an owner-occupant doing the work alone is exempt. Check the licence in the RBQ register before signing. Régie du bâtiment du Québec
• Contractor invoices in Québec carry GST 5 % plus QST 9.975 %, 14.975 % in total. Revenu Québec
• The Office de la protection du consommateur advises a written contract that describes the work, the materials by type and quantity, the start and end dates, the total price and the contractor’s liability insurer, a small deposit only, and no final payment before the work is finished to your satisfaction.

• Health Canada says a home built before 1960 probably contains lead-based paint, and one built between 1960 and 1990 may on the exterior. Disturbing it releases lead dust: no sanding, heat guns or blowtorches on old paint without a test, and keep children away from the work. Santé Canada
• In a divided co-ownership, work on common elements (roof, façade, balconies, party walls) goes through the syndicate, which since 14 August 2025 must hold a reserve-fund study renewed every five years by an independent professional; a special assessment may be how your share of a major job gets paid.

What to ask the contractor before you sign

• Check the contractor’s RBQ licence in the online register: the number, the subcategories, and that it is active. No licence, no contract.
• Ask for proof of liability insurance and, where it applies, workers’ compensation coverage, dated within the year.
• Get a written contract that lists the scope, the materials by brand and grade, the schedule, and what is excluded.
• Agree on a deposit that matches materials ordered, not a share of the whole job, and tie further payments to milestones you can see.
• Ask who pulls the permit, who schedules inspections, and whether the quote includes the permit fee.
• Compare three quotes on the same written scope; the cheapest one usually left something out.
• Ask for two recent references for the same kind of job, and call them.
