How much does it cost to replace a garage door spring in Fredericton NB?

Replacing a garage door spring in Fredericton typically costs between $200 and $450 for a single spring, or $350 to $600 if both springs are replaced at the same time, which is the recommended approach since springs installed together tend to wear at the same rate and the second one usually fails shortly after the first.

The cost breaks down into two main components: the spring itself and the labour to install it. A standard torsion spring for a residential garage door runs $50 to $150 for the part, depending on the wire gauge, length, and cycle rating. Higher-cycle springs (rated for 20,000 to 50,000 cycles rather than the standard 10,000) cost more upfront but last significantly longer, which is worth considering in Fredericton where the door gets heavy seasonal use — think of how many times you open and close it during winter alone. Extension springs, which are found on some older or lighter single-car doors, are generally less expensive at $30 to $80 per spring, but torsion springs are the industry standard for most modern installations because they provide smoother, more balanced operation.

Labour is the larger portion of the bill, and for good reason. Garage door torsion springs are under extreme tension — enough to cause serious injury or death if they release unexpectedly. This is one job that should never be a DIY project regardless of your mechanical aptitude. A qualified garage door technician in Fredericton will typically charge $150 to $250 for the service call and labour, which includes removing the old spring, measuring and installing the replacement, balancing the door, lubricating all moving parts, and testing the safety mechanisms. Most technicians in the Fredericton area can complete the job in under an hour.

What Affects the Price in Fredericton

Several factors influence where your cost falls within that range. Door size and weight are the primary variables — a heavy insulated double door (16 feet wide, R-16 rated) requires beefier springs than a lightweight single non-insulated door, and those springs cost more. The height of the door also matters because taller doors require longer springs with different winding specifications. If your garage door hardware is older and the technician discovers worn cables, rollers, or bearing plates during the spring replacement, addressing those items at the same time adds $50 to $200 but prevents a second service call down the road.

New Brunswick's Maritime climate does affect spring longevity. The combination of cold winter temperatures, road salt tracked into the garage, and humidity accelerates corrosion on uncoated springs. In Fredericton, where winter temperatures regularly drop below -20 degrees Celsius, the metal in garage door springs contracts and becomes more brittle, which is why most spring failures in NB happen during the coldest months of the year. Investing in galvanized or powder-coated springs adds $20 to $50 per spring but significantly extends their lifespan in this climate.

A typical garage door spring in New Brunswick lasts 7 to 12 years with standard-cycle springs, or 15 to 20 years with high-cycle springs, assuming regular lubrication. Applying a silicone-based lubricant to the springs, hinges, and rollers twice a year — once in spring and once before winter — reduces friction, prevents corrosion, and extends the life of all the door's moving components.

When you need a spring replaced, get two to three quotes from local garage door companies or general contractors who service overhead doors. Most will provide a firm quote over the phone once you tell them your door size, type, and whether it uses torsion or extension springs. If you are unsure about your spring type, a photo of the hardware above the door is usually enough for a technician to identify what you need.
