No matter what size or shape your opening, there's a door to fit your budget and taste.
What to measure. Before you shop for a sectional door, the only type that comes in stock sizes, measure the height and width of the opening to see if you need an off-the-shelf or a custom size. Most stock sectional doors cover openings 7 to 8 feet high and 9 to 16 feet wide. Doors for much bigger openings and nonsectional doors are custom built, so have a pro do the measuring.
Where to buy. Find stock and semicustom doors for standard openings at home centers, window-and-door retailers, and garage-door distributors. The salesperson can recommend an installer, who should double-check everything before you place the order. Order custom doors directly from a manufacturer or through its distributors.
How long it takes. Stock steel doors can be delivered as soon as the following day or up to two weeks after the order is placed. Semicustom steel takes three to six weeks; a custom wood door, eight to nine weeks. Professional installation takes about half a day, regardless of type.
What's included. New tracks, rollers, spring, and hinges are typically part of the door's purchase price. Installation and removal of old doors are not. Expect to pay $100 to $500 to have the new door put in and $75 to $200 for the old door to be taken away.
