What should homeowners know about garage door maintenance?

Jason Carter: The springs are the most common part to break on a garage door. That's also the most common scam that's out there. A lot of companies will tell customers they need seven different parts in addition to the springs, and charge them $500 to $600. We charge $225 to replace springs on a two-car garage, and that includes tax, labor and galvanized springs.

Michael Dryer: Garage door springs are typically designed for only 10,000 cycles, so it depends how often you open and close the door. To replace and service the springs costs about $175, but that includes a full diagnostic check of the garage door system, including greasing the motor gears.

What are some repairs homeowners can do themselves?

John Edelen: Customers can lubricate the door and its components at least a couple of times a year.

Carter: Lubricate the door, or get a tuneup once in awhile. A tuneup costs about $69. I recommend using a silicone-based lubricant.

Do extreme cold or hot temperatures affect garage doors?

Dryer: If your garage door faces west out here in Phoenix, you can pretty much fry an egg on a steel garage door. Insulation keeps the heat and cold out.

Edelen: Not so much hot weather, but extreme cold affects a garage door's operation. We recently had a streak of days in single-digit temperatures, and our service-call volume increased considerably.

What types of garage doors are available and how much do they cost?

Carter: All garage doors in Florida are wind-loaded because of the hurricanes. The bracing on the back makes them heavier. The average weighs 300 to 400 pounds, but some can weigh as much as 800 pounds. It costs about $1,000 to replace a two-car steel garage door, or about $5,000 if it's made of wood. Some customized high-end doors can cost as much as $20,000 to $30,000.

Edelen: The carriage-style doors are becoming very popular. They're designed to look like carriage house doors from the days of old, but they work like a standard overhead door. To get into the true carriage house style, $2,500 to $2,600 will get you a very nice door. If you get into the higher-end wood products, it'd probably start at $6,000 to $7,000.
