What are the pros and cons of steel versus wood versus fiberglass garage doors for Ottawa's climate?

Steel is the best all-around choice for most Ottawa homeowners, but each material has legitimate strengths and weaknesses worth understanding before you commit.

Steel doors dominate the Ottawa market for good reason. They handle the temperature swings from plus 35 in summer to minus 30 in winter without warping, cracking, or expanding significantly. A quality insulated steel door with polyurethane foam gives you R-16 or higher insulation in a package that requires almost no maintenance. You wash it once a year and touch up any paint chips to prevent rust, and that is about it. Steel doors are also the most affordable option, with a standard insulated single door running $1,500 to $2,500 installed. The main downside is dent susceptibility. A stray hockey puck, a bicycle handlebar, or a chunk of ice knocked off your car will leave a dent that cannot be easily repaired. Steel doors also have a more uniform, manufactured look that some homeowners find plain, although modern stamped patterns and woodgrain finishes have improved the aesthetics considerably.

Wood garage doors are beautiful. There is no getting around the fact that a real wood carriage house door looks stunning on the right home. Cedar and hemlock are the most common species used in Ottawa. They offer natural insulation, can be stained or painted any colour, and bring a warmth and character that no other material can match. However, wood is high maintenance in Ottawa's climate. The freeze-thaw cycles, combined with road salt spray and humidity changes, mean you need to refinish a wood door every two to three years to keep it from cracking, warping, or rotting. A quality wood door starts around $3,500 for a single and $5,000 or more for a double, installed. Over a 20-year lifespan, the maintenance costs can add another $3,000 to $5,000 on top of that. Wood doors are also heavier, which means heavier-duty springs and opener systems.

Fiberglass doors offer some unique advantages for Ottawa. They do not rust, they do not rot, and they do not dent as easily as steel. They resist salt corrosion well, which matters if your garage faces the street and gets hit with road salt spray all winter. Fiberglass can be molded to look like wood grain, giving you something close to the wood aesthetic with much less maintenance. The downside is that fiberglass becomes brittle in extreme cold. At minus 25 or below, a fiberglass door is more likely to crack on impact than a steel door would be. It could be something as simple as a delivery person bumping it with a heavy package. Fiberglass doors also tend to yellow over time with UV exposure, though this is a slower process in Ottawa than in sunnier climates. Pricing falls between steel and wood, typically $2,200 to $3,800 for a single door installed.

For most Ottawa homes, an insulated steel door with a woodgrain finish gives you the best balance of performance, appearance, durability, and cost. If curb appeal is your top priority and you do not mind the upkeep commitment, wood is a beautiful choice. Fiberglass works well in specific situations, particularly for homes near busy roads where salt exposure is heavy.
