Instant Doors Estimate for Long Island Homes
Six questions, one ballpark, no obligation. We built this because every other contractor makes you fill out a form, wait 3 days, and then calls you with a "special offer." Ours is a calculator.
How big is the exterior?
Exterior wall area in square feet
Not sure? Multiply your house perimeter (in feet) by its wall height. A 35 x 28 ft ranch = 126 ft perimeter x 10 ft = ~1,260 sqft. A 2-story colonial might be closer to 2,000+.
How our door estimate works
This calculator uses real pricing data from 2800+ door installation jobs across Nassau and Suffolk County since 2011. It accounts for house size, number of stories, material choice, and condition of the existing exterior.
The result is a ballpark range, not a fixed quote. It gets most homeowners within 15% of the final number. The gap comes from variables we cannot see remotely: the condition of the sheathing behind the old doors, how many corners and angles your house has, window and door trim complexity, and whether there is asbestos underneath that needs professional abatement.
To get the real number, schedule a free walk-through. James or Ryan will come out, take measurements, show you physical material samples, and discuss any site-specific factors. You get a written quote within 48 hours. No deposit to hold a date, no follow-up pressure, no expiration date on the quote.
Every quote includes: full tear-off of existing door, Tyvek house wrap, new door installation, all trim and flashing, permits (we pull them), debris hauling and dumpster, daily jobsite cleanup, and our 10-year workmanship warranty.
