Factors that affect the final price
Door brand and model
Brands like Novatech, Alumicor, or Kolbe use standardized parts that are readily available. Imported or obsolete models may require special-order parts, increasing cost and lead time.
Glass dimensions
A large double-door thermos (1.8m x 2.4m) costs more than a standard single panel. Low-E, tinted, or UV-treated glass also carries a 15-30% premium.
Accessibility and floor height
A ground-floor door is faster to service than a 3rd-floor balcony without a service elevator. Difficult access can add 30-60 minutes of labor.
Age and overall condition
A 25-year-old door with corroded frame and worn mechanisms often needs multiple simultaneous interventions, which is more economical as a package than separate visits.
Repair vs Replace: the economics
A new mid-quality sliding patio door, installed, costs $2,000 to $5,000 in Montreal in 2025. If your door is under 20 years old and the frame is in good condition, repair is almost always the better economic choice. For example, replacing rollers ($150-300) + thermos ($350-750) + weatherstrip ($100-250) totals $600-1,300 — roughly 3 to 4 times less than a new door. Plus, repair preserves your home's existing aesthetic and avoids finishing work (drywall, paint, flooring) associated with full replacement. Our approach is simple: we only recommend full replacement when the frame is corroded, multiple mechanisms are simultaneously defective, or you want to change styles. In all other cases, we prioritize targeted, piece-by-piece repair with transparent quoting before every intervention.
