Everything you need to know about patio door repair in Montreal

Most common repairs (rollers, lock, handle, weatherstripping) are completed in 45 to 90 minutes. Thermos replacement requires two visits: measurements (20 minutes) and installation (60 minutes per panel), with 5 to 10 business days between them for custom glazing fabrication.

We serve all of Greater Montreal, including Montreal (all boroughs), Laval, Longueuil, Brossard, West Island, South Shore, North Shore, Terrebonne, Repentigny, Saint-Bruno, Boucherville, Chambly, Dollard-des-Ormeaux, Kirkland and more than 40 other cities. Our average response time is less than 3 hours in all these zones.

Yes, we offer emergency service 7 days a week, from 7am to 9pm. For security issues (blocked lock, door that won't close) or significant water infiltration, we prioritize same-day interventions in most areas. A surcharge of $50 to $100 applies for evening or weekend emergencies.

All our repairs are covered by a complete 1-year warranty on parts and labor. If the same problem reappears within 12 months, we come back for free and repair at no extra charge. For replaced thermos, the warranty against internal condensation is 10 years.

Price differences are explained by part quality (standard vs premium OEM), technician experience, warranty offered, and travel fees. Beware of abnormally low rates (less than $100 for roller replacement) which often hide generic hardware store parts or technicians without RBQ certification. Our pricing grid is transparent and published on our website.

Yes. If we perform multiple interventions on the same visit (for example: rollers + weatherstripping + adjustment), travel fees are shared and we apply a 10% discount on the total. This often represents a saving of $100 to $300 compared to three separate visits.

Absolutely. Our video diagnosis is 100% free and without commitment. You receive a precise quote by email or SMS, based on your video and your exact door configuration. You are free to accept, decline, or compare with other companies. No credit card is requested at the time of diagnosis.

Technically yes, but practically it's risky. The door panel weighs 40 to 150 kg. Lifting it without industrial suction cups and proper supports is dangerous. Also, alignment must be precise to the millimeter — a 2 mm error makes the door drag or prevents the lock from working. We recommend our free video diagnosis to evaluate if your case is suitable for DIY.

Sometimes condensation is less visible in summer because the temperature difference between the two panes is smaller. However, the thermos seal remains defective and moisture continues to penetrate. The problem systematically reappears the following winter, often worse. White mineral deposits that form over time become irreversible. Glass replacement is the only durable solution.

On-site measurement takes 20 minutes. Custom glazing is fabricated in a specialized workshop on the South Shore and delivered in 5 to 10 business days. Installation itself takes about 60 minutes per panel. The entire process, from diagnosis to finishing, is typically completed in 7 to 12 days.

We master the main brands installed in Quebec: Novatech, Gentek, Ostaco, Alumipro, Alumicor, Kolbe, and many others. We maintain a stock of parts for the most common models. For rare or imported brands, we order specific parts with a 3 to 5 business day delay. Our free video diagnosis allows us to identify the exact brand and model before any intervention.

Ideally in October or November, before the first sustained freezes. This leaves time to order parts if necessary and to intervene in comfortable conditions. Preventive maintenance in autumn avoids 80% of winter breakdowns. We offer free pre-winter inspections by video diagnosis in September and October.

No, absolutely not. De-icing salt (calcium chloride) rapidly corrodes the aluminum of the frame, rollers, and track. In 2 to 3 seasons, you can transform a slightly oxidized track into a completely corroded one requiring costly replacement. Use diluted white vinegar (1:1 with warm water) or pure warm water to de-ice without damaging components.

Annual preventive maintenance extends roller lifespan by 30 to 50%. A well-maintained patio door in Montreal can last 25 to 30 years, compared to 12 to 15 years for a neglected one. The 20 minutes of seasonal maintenance (cleaning, lubrication, inspection) represents one of the best returns on investment for your home.

Yes, all our technicians are bilingual French-English. Whether you are in Montreal, West Island, or elsewhere in the region, you will be served in the language of your choice. Our website, quotes, and warranties are available in French and English.

Replace the entire door only if the aluminum frame is corroded beyond repair, if several critical mechanisms fail simultaneously, or if you want to change style. In 85% of cases, repair (rollers + thermos + weatherstripping) costs $600 to $1,300 — that is 3 to 5 times cheaper than a new door ($2,500 to $5,500). Our free video diagnosis gives you an honest assessment of your door's condition.
