Steel, wood or fiberglass? How to choose a replacement garage door
Updated · KeystoneProGuide editorial team
How do you choose a replacement garage door?
Start with the material, because it sets both the price and the upkeep. Then decide whether insulation is worth paying for in your garage, confirm the size with a measurement on site, and make sure the price covers everything that goes with the door: track, springs, removal of the old one and the installer's warranty. Steel is the most common choice and among the cheapest. Wood costs the most to buy and to keep.
What does each material cost, and how does it hold up?
Two publishers print prices by material. Angi's are replacement costs per door. HomeGuide's are for a single door without installation.
| Material | Angi, per door | HomeGuide, door only | Points the publishers make |
|---|---|---|---|
| Steel | $650 to $3,200 | $250 to $2,500 | Most common; single-layer steel dents easily and insulates poorly |
| Aluminum | $600 to $2,900 | $250 to $1,400 | Resists rust; dents easily; light on the springs |
| Wood | $900 to $4,500 | $1,000 to $4,000 | Needs regular staining or painting; can warp and rot |
| Composite | $650 to $4,800 | $300 to $4,000 | Wood look over a metal frame; resists warping and moisture |
| Vinyl | $800 to $2,500 | $300 to $2,500 | Very little maintenance; can crack on impact in extreme cold |
| Fiberglass | $800 to $2,700 | $350 to $3,500 | Resists rot and rust; can crack on impact in extreme cold |
A few of those notes deserve a sentence more. On steel, Angi says aluminum is rust-proof but steel is not, while HomeGuide says galvanized or coated steel resists corrosion and that steel doors come in one, two or three layers, the triple-layer kind being the strongest and the best insulated. On wood, HomeGuide warns that a heavy wood door needs heavy-duty tracks and a stronger opener. Angi sums up the budget view: steel and aluminum are the least expensive, and vinyl is a mid-priced choice that some owners pick for its low upkeep.
How long a door lasts is less clear. HomeAdvisor and HomeGuide both give 15 to 30 years for doors in general, but they disagree about wood: HomeAdvisor says wood doors often reach 20 to 30 years, and HomeGuide's table gives solid wood 8 to 12. Neither explains the gap.
Is an insulated door worth paying for?
It depends on the garage more than the door. The prices: Angi gives $1,100 to $4,200 for an insulated door, HomeGuide $600 to $3,000 or more, and Fixr $700 to $2,300 installed. Insulation is rated by R-value, on a scale that Angi puts at 0 to 20.
The publishers agree on when it pays.
- When the garage is attached. HomeAdvisor says an insulated door can save on heating bills if the garage is attached to the house. Fixr says most homeowners with an attached garage benefit, while a detached garage might do just as well without.
- When the rest of the garage is insulated. HomeGuide is the strictest: an insulated door is only worth it if the garage walls, ceiling and windows are properly insulated too, with weatherstripping around the door.
- When you use the space. Angi says insulation is worth considering if you work in the garage or store things there that are sensitive to temperature.
Insulated doors have two side benefits that HomeGuide mentions: they resist dents better and they run more quietly. No government or university source on garage door insulation could be read for this guide, so these are the cost publishers' views.
What size and style do you need?
The opening decides the size. Angi describes the standard single door as 7 to 10 feet wide and 7 to 8 feet tall, and HomeGuide prices a single door at 9 by 7 feet and a double at 16 by 8. By size, Angi gives $500 to $3,000 for a one-car door and $800 to $5,000 for one double door on a two-car garage.
On style, the sectional door, made of panels that roll up on a track, is the most popular, and Angi prices it at $500 to $1,800. A carriage house door runs $1,200 to $8,000. The one-piece tilt-up door is still sold, but HomeGuide describes it as less safe than a sectional door and notes that it relies on extension springs.
Whatever you choose, HomeGuide says a contractor must measure in person before giving a final estimate and ordering the door.
What does installation add to the price?
HomeGuide breaks an installed door into parts: $400 to $1,100 for the door, tracks and hardware, $150 to $700 for labor, $50 to $250 to remove the old door where that is not included, and $200 to $1,000 or more if the opening has to be resized. Angi puts labor at $200 to $500 and removal at $50 to $200.
Three things should come with the door.
- Its own track. DASMA, the manufacturers' trade association, says an old track may not fit a new door, and that the track designed for the door should be used.
- Springs matched to its weight. HomeGuide notes that heavier insulated doors need stronger springs.
- A working opener connection. Ask whether the existing opener suits the new door. HomeGuide lists "requires a new opener system" among the questions to put to an installer.
HomeAdvisor says a replacement takes three to six hours.
Do you need a permit, and does old paint matter?
In most of Pennsylvania a like-for-like door is unlikely to need a permit, but your municipality decides. The state's construction code regulation leaves alterations that make no structural change outside the code, and says a minor framing change needed to replace existing windows or doors is not a structural change. Local ordinances can add requirements. Enlarging the opening is different: cutting a structural beam or a load-bearing wall is not an ordinary repair under the regulation. Angi says a permit, where one is required, typically costs $40 to $120 and that the installer normally obtains it.
Philadelphia has two rules of its own. The city says a building permit is often not needed to replace doors and windows in a one- or two-family dwelling, unless the property is on the historic register. For registered historic properties, the city's list of work that needs Historical Commission review names garage doors.
Old paint matters in an old house. The Environmental Protection Agency requires any firm paid to do work that disturbs painted surfaces in a home built before 1978 to be certified in lead-safe practices. If a painted wooden door or its frame is coming out of an older house, ask the installer about that certification.
What should you get in writing?
HomeGuide's list is the practical one: warranties on both the door and the installation labor, a written copy of the contract, an estimate with costs and materials by line item, and a payment schedule that leaves money owing until the installation is complete. It says a standard door carries a 10-year manufacturer warranty. Angi adds that manufacturers may void a warranty if the door is not installed by a certified professional, which is worth asking the installer about.
Pennsylvania law requires a written, signed contract for a home improvement over $500, and limits the deposit on a job over $5,000. The Pennsylvania rules guide has the details, repair or replace helps with the earlier decision, and installers are on the garage door repair directory page.
