When to replace rather than repair?
A patio door over 25 years old with a wood frame rotten from water infiltration or catastrophic energy performance generally does not deserve repair. Complete replacement with a modern model costs between $2,000 and $4,500 depending on dimensions and chosen options. Obsolete patio doors compromise your home security with outdated locks and zero thermal insulation. RBQ partner glaziers evaluate free of charge whether replacement is the best option.
New patio door: long-term savings
A modern patio door with Low-E glazing and triple pane reduces heat loss by 40% compared to a 1985 door. Depending on your opening dimensions, return on investment is achieved in 7 to 12 years thanks to winter heating savings. In addition, certain new Energy Star certified patio doors are eligible for Quebec government Rénoclimat subsidies. RBQ partner glaziers advise on the best glazing based on your facade orientation.
Repair vs replacement: when to replace your patio door?
Patio door repair (/en/patio-door-repair/) suits occasional breakdowns (rollers, lock, track). Complete replacement is recommended when the frame is damaged, the door is over 25 years old, or energy performance is obsolete.
When to replace your patio door in Quebec?
Patio door 25+ years old out of service
Beyond 25 years, parts become scarce and thermal insulation no longer meets current Quebec standards. Replacement with a new Low-E model is often more cost-effective.
Rotten frame (wood door)
A wood frame rotten from water infiltration cannot be durably repaired. The RBQ glazier partner replaces the complete door + frame with a resistant aluminum or vinyl model.
Energy performance too low
Old single-pane door or defective thermos? Replacement with a triple-glazed Low-E argon model reduces your heating bill by 20 to 30%.
Security compromised (obsolete locks)
Outdated lock, non-tempered glass or failing locking mechanism? Your family's safety comes first. The RBQ glazier partner installs a new door compliant with standards.
Aesthetic renovation
Change the look of your living room or kitchen with a modern patio door: custom finishes, large glass, minimalist frame. The RBQ contractor partner advises on current trends.
