Prices come from the Long Island price survey. Most published figures are “starting at”, so options push totals higher.
What drives the price
- Size. Non-standard openings, common in older Nassau garages, mean special-order doors.
- Insulation. Polystyrene or polyurethane cores. Insulated doors are quieter and stiffer.
- Windows and hardware. Decorative glass, handles and hinges on carriage styles.
- Wind rating. Coastal homes may need a wind-load-rated door. See wind-rated garage doors.
- What’s replaced with it. New tracks, springs and weather seals come with most new doors. Ask if the opener is included.
Permits and design review
A garage door installation that changes the size of the opening or the header needs a building permit everywhere on Long Island. For a same-size door, the answer depends on who issues permits for your address. Incorporated villages run their own building departments, and some, like Garden City’s Architectural Design Review Board and Southampton Village’s Architectural Review & Historic Preservation Board, review exterior changes. Find your office in the Long Island garage door permit guide.
Wind-load testing
New York’s Residential Code (Section R609.4 in the 2020 edition) requires garage doors to be tested for wind load to ASTM E330 or ANSI/DASMA 108. New doors carry a label with their design pressure rating. On the South Shore, the barrier islands and the East End, ask the installer which rating your address needs. More in wind-rated garage doors.
Repair or replace?
Replace when panels are cracked, rusted through or rotted, when the door is too heavy to balance, or when you’re changing the style. Repair when it’s springs, cables, rollers or one damaged panel: a panel replacement or spring job costs a fraction of a new door.
What the installation day looks like
- Release spring tension and remove the old door, tracks and springs.
- Check the jambs and header. Soft or rotted wood is common in older garages and needs repair first.
- Install the new sections, tracks, springs and cables, then balance the door.
- Reconnect or install the opener and test the auto-reverse.
- Haul away the old door (ask whether that’s included).

Frequently asked questions
How much does a new garage door cost on Long Island?
Published Long Island prices: single-car steel $1,550 – $1,995, two-car steel $2,500 – $2,950, carriage-house from about $2,500, and wood or full-view aluminum and glass $3,600 – $3,900, installed.
How long does garage door installation take?
Removing the old door and installing a new sectional door is usually a one-day job. Custom sizes, wood doors and full-view glass doors are made to order, so the wait is for the door, not the install.
Do I need a permit for a new garage door on Long Island?
It depends on the town, village or city. Changing the opening size needs a permit. A same-size replacement varies, and villages such as Garden City and Southampton have design review boards. See our permit guide for the office that covers your address.
Is an insulated garage door worth it?
For an attached garage, a garage under a bedroom, or a garage you use as a workshop, usually yes. Insulated doors are also stiffer and quieter. On published LI prices the insulated single-car steel door cost a few hundred dollars more than non-insulated.
What size garage door do I have?
Measure the opening width and height inside the garage. Common sizes are 8x7 and 9x7 for single doors and 16x7 for doubles. Older Long Island garages often have smaller or non-standard openings, and headroom above the opening limits which track systems fit.
Should I replace the opener at the same time?
If the opener is old or a chain drive under a bedroom, replacing both at once saves a second visit. New openers installed ran $250 – $875 on published LI prices.
