Welded work like grease duct
If the duct is welded to a kitchen's drawings, its price depends on the welds, the slope, and the access openings. A person prices those from the drawings.

WHAT YOU CAN PRICE ON WEBDUCT AND WHAT GOES TO A QUOTE
WebDuct prices any duct or fitting whose price depends only on its sizes. A piece goes to a quote when its price depends on more than that.
You can order ductwork online through WebDuct, our ordering portal, once your company has an account. Straight duct and the fittings we build, from elbows and offsets to transitions, takeoffs, and plenums, are listed with instant prices. Pieces whose price depends on more than their sizes start with a quote. That covers grease duct, lined duct, curbs, kitchen stainless, and anything installed. This guide shows which route each piece takes, what to have ready, and what happens once you submit.

The route depends on whether the sizes alone set the price. Find each piece on your list below.

|---|---|---|
| Straight rectangular duct | WebDuct | It's priced by its width, height, and length |

| Curbs and curb adapters | A quote | They're sized to the unit's model number |

WebDuct is the online portal we use to price and take duct orders. Knowing who sets it up explains what you'll find in it.
Because the order goes straight to us, nobody retypes your sizes. That takes one chance of a mistake out of the job. Your company needs a WebDuct account before anyone can order, so call or send a request and say it's for WebDuct.
Ordering online works best with the duct list in front of you. Each piece is built from its sizes.

Submit the order. It goes straight to our computer.
How to measure ductwork for a custom fitting shows how to take sizes the right way round. How to specify a duct fitting covers the joints and bends beyond the sizes.
A piece goes to a quote when its price depends on more than its sizes. These projects usually need a quote:
If the duct is welded to a kitchen's drawings, its price depends on the welds, the slope, and the access openings. A person prices those from the drawings.
If a curb or curb adapter has to fit a unit, we need the model number and sizes. Then we price it to match.
If you need counters, sinks, or shelves, they're made to your specs. Each is priced based on its size, sink count, and edge details.
If your spec calls for lining, we buy it in and fit the type you need for the duct. The lining changes the price, so it's quoted.
If you want the duct installed, the site sets the price. Access, height, and parking all change the hours.
If your fitting isn't in the list, send a drawing or sketch with sizes. If we have to draw it, a drawing fee applies, credited when you order.
Site conditions that change a ductwork installation cost explain what moves an install price. Shop drawing fees and design assist explains the drawing fee.
Most jobs use both routes at once. Typical lead times count from the approved order or drawings and any deposit, and depend on the size of the order.
| Piece | Route | Typical lead time |
|---|---|---|
| Straight duct | WebDuct | 1 to 2 days |
| Listed fittings | WebDuct | 1 to 2 days |
| Grease duct | A quote | 1 to 2 days |
| Stainless kitchen pieces | A quote | 1 to 2 weeks |
| Curbs and anything installed | A quote | Confirmed when it's quoted |
Pricing both routes together keeps the job on one schedule. Sheet metal fabrication lead time explains when a lead time starts.
An online order is only as good as the sizes typed into it. These are the slips that send one back.
| What happened | What it causes | What to do instead |
|---|---|---|
| Outside sizes entered where inside was meant | The fittings come out the wrong size | Check inside or outside before you submit |
| Width and height swapped | The fitting turns the wrong way on site | Label width and height as the drawing does |
| Kitchen stainless steel searched for on WebDuct | It isn't listed, and the order waits | Send made-to-spec pieces for a quote |
| Duct ordered online and the quoted pieces requested days later | The pieces arrive on different days | Send the quote request with the online order |
| Sizes entered before the space was final | A piece is remade after the site changes | Measure once beams and ceilings are in |
Your order reaches us the moment you submit it. From there, it runs the same way every time.
We check it before it's cut. If something looks off, we ask before cutting.
Work starts once the order is approved and any deposit is in. That's when the lead time begins.
Duct and fittings typically take 1 to 2 days. The time depends on the size of the order.
Pick it up or have it delivered. We deliver by our van or a delivery service.
If the mistake was ours, we remake it. There's no charge for fixing our own error.
Our custom duct fittings and HVAC ductwork fabrication pages cover what we build for these orders.
WebDuct suits a duct list you can size yourself. A call suits anything you're not sure of.

If you're unsure about a size, call before you submit. A two-minute check costs less than a fitting made twice.
With these in hand, a duct package can be priced in one sitting. Anything left over goes on the quote request.
More guides on ordering duct sit in HVAC Ductwork and Fittings. Stock duct fittings or fittings made to size help you decide which pieces need making at all.
A duct list in any form is enough to start. Price what WebDuct lists online, send the rest, and we'll say what's missing.
