Commercial Door Quote Calculator

Give your commercial door company a quote form that works like your estimator. Facility managers and contractors choose between insulated sectional, rolling steel, high-speed fabric, fire-rated rolling and full-view aluminum doors priced per square foot of opening, then enter the opening in feet with the headroom and side room in inches, and the form tells them which track fits: standard lift, low headroom, high lift or vertical lift. Operators are sized to the traffic (chain hoist, trolley, jackshaft or heavy-duty three-phase) with loop detectors, motion sensors, timers, traffic lights and safety devices. Loading dock positions get levelers, seals, bumpers and vehicle restraints; hollow metal man doors, tear-out, permits, lift rental, after-hours work and freight-only orders are all covered. The estimate comes as a range with a volume discount from three doors, and the request collects the company, contact and facility address needed for a purchase order, with a downloadable PDF estimate.

Expect $5,200 – $6,600 (±12%): the range covers what the site survey usually turns up. Planned maintenance: $325/yr under a separate agreement, not part of the order.
An estimator calls with a door proposal and sets up a free site survey within 3 business days. After the survey you get a firm quote, and the door is installed about 6 weeks later.

Frequently Asked Questions

Can I change the price per square foot for each door type?

Yes. Every rate is a named constant at the top of the calculator code: the per-square-foot price of each door type and insulation level, the percent surcharges for custom color, wind rating, wide doors and lift type, and the fixed prices of operators, controls, dock equipment, man doors and installation. Change the numbers and the whole estimate follows.

How does the calculator decide which track fits the opening?

From the headroom the customer enters in inches. With at least 18 inches above the opening standard-lift track fits; between 9 and 18 inches the door needs a low-headroom kit; from 36 inches high lift becomes available, and vertical lift when the headroom exceeds the door height plus 12 inches. Below 9 inches the form says the survey has to settle it. All thresholds are constants you can change.

Is dock equipment priced per door?

Yes. When the customer marks the opening as a loading dock, the leveler, seal or shelter, bumpers and vehicle restraint are added for every door on the request, because each dock position is outfitted separately. If only some of the doors are docks, the customer says so in the notes and your estimator adjusts the quote.

Why is the estimate shown as a range?

A site survey almost always changes something: the exact opening, the side room, the power at the door. The calculator computes one number and shows it with a configurable ±12% range so the customer has realistic expectations and your estimator has room to finalize after the survey. You can narrow the range or show the exact figure.

What information does the lead include?

The company name, the contact's name and title, phone, email and the facility address, plus everything that went into the estimate: door type and finish, opening dimensions, track, operator and controls, dock equipment, man doors, installation scope, permit and timing. A PDF estimate with the same breakdown can be downloaded by the customer and attached to your follow-up.
