Why Your Neighbor Paid $180 and You Paid $280 for the Same Repair
The final price depends on concrete factors, not the technician's mood. Here is what makes the difference between the low and high end of each range:
Brand and model
Rollers for a Novatech or Gentek door (most common in Quebec) cost $35-55 per unit. Those for an imported or obsolete brand can cost $80-120 and require 3-5 days to order. We tell you during the video diagnosis.
Glass dimensions
A double door thermos at 180x240 cm costs nearly double a standard single panel at 76x213 cm. Low-E glass (recommended for gas-heated homes) has a 15-30% surcharge, but reduces heating bills by 10-15% annually.
Accessibility
A ground-floor door in Brossard: 45-minute intervention. A 3rd-floor balcony without elevator in Verdun: 90 minutes with safety equipment. Extra time is reflected in the price.
Age and general condition
A 25-year-old door with frame corrosion often requires repairing several components simultaneously (rollers + rail + weatherstripping). But we apply a 10% discount when multiple interventions are done in one visit. Result: you pay less than if you called us 3 times.
Repair vs. Replace: The Calculation Your Real Estate Broker Will Make
If you plan to sell your home within 3 years, know this: a defective patio door reduces the perceived value of your property by $2,000 to $4,000 in buyers' eyes. They see a door that grinds, a fogged thermos, or a stuck lock as a "problem to fix" — and they reduce their offer accordingly.
A new sliding patio door installed costs $2,500 to $5,500 in Montreal in 2025. But if your door is less than 20 years old and the aluminum frame is intact, repair is almost always the best economic option.
Take Robert, a homeowner in Repentigny whose door was 12 years old. Worn rollers ($220) + fogged thermos ($480) + hardened weatherstripping ($150) = $850 total. We applied the 10% multi-service discount: $765. His door works like new. Full replacement would have cost $3,200. He saved $2,435 — and his home retains its value.
Our golden rule: we only recommend full replacement when the frame is corroded beyond repair, or when you want to change the style/model. In 85% of cases, repair is the smart choice.
Our Transparency Guarantee: The Quoted Price = The Price Paid
All our prices are communicated in writing before any intervention. The free video diagnosis gives you a precise quote adapted to your specific situation. If unexpected issues arise during the work — for example, a more corroded frame than anticipated — we consult you BEFORE adding anything. You have the right to say no, with no fees.
Beware of abnormally low rates (under $100 for roller replacement). They usually hide generic hardware-store parts that last 6 months, or technicians without RBQ certification. A good certified technician in Montreal charges $80-120 per hour plus quality parts. If it's too good to be true, it is.
Our commitment: the price we quote is the price you pay. No "surprise travel fees", no "tooling surcharges", no "additional taxes". Fixed. Clear. No surprises.
