What a siding estimate includes, line by line
A siding quote usually arrives as one number, sometimes with a price per square foot next to it. Both look like answers. Neither tells you what the crew will actually do to your house, and that is the part that decides whether two quotes can be compared at all.
The clearest way to see it is to read a full estimate line by line. Below is one: a facade estimate GetFacade generated for a two-story house in the US Midwest, with the siding replaced by fiber cement, new windows and entry door, a rebuilt porch and new gutters. It has 16 lines, 9 for materials and 7 for labor, and a schedule of 21 days.
The dollar total is left out on purpose. Totals move with your region, your contractor and the season. The shares below hold up much better, because they describe how the job is built.
Labor is more than half of this estimate
In this estimate, labor is 55% and materials are 45%. The siding itself, the thing the homeowner spends weeks choosing, is a smaller line than the work of putting it on.
| Line | Section | Share of the estimate |
|---|---|---|
| Installing fiber cement lap and vertical siding | Labor | 31% |
| Fiber cement lap siding and vertical accent panels | Materials | 16% |
| New double-hung windows | Materials | 11% |
| Window and door installation, with flashing and sealing | Labor | 6.5% |
| House wrap and seam tape | Materials | 5.5% |
| Removing and hauling away the old vinyl siding and gutters | Labor | 5% |
| Painting trim, foundation and stairs | Labor | 4.5% |
| Porch railing system | Materials | 3.5% |
| Porch rebuild: column wraps and railing mounting | Labor | 3.5% |
| Scaffolding, site protection and permit handling | Labor | 3% |
| Fiberglass entry door | Materials | 3% |
| Seamless gutters and downspouts | Materials | 2.5% |
| Exterior paint for trim and foundation | Materials | 1.5% |
| Column wraps and post sleeves | Materials | 1.5% |
| Gutter and downspout installation | Labor | 1.5% |
The estimate lists lap siding and vertical accent panels as two lines; the table joins them into one. Shares are rounded to the nearest half percent, so the column adds up to roughly 100%.
Two numbers from this table are worth remembering. Installing the siding costs almost twice as much as the siding boards themselves. And the siding, boards plus installation, is less than half of the whole job. The other half is windows, the door, the porch, gutters, paint, wrap, removal and setup.
The labor rates in this estimate are the model's figures for a Midwest residential contractor, not published statistics. Your own quotes will carry different rates. What stays useful is the structure: which lines exist, and how large each one is compared with the others.
The lines that come before the first board
Three lines in this estimate describe work the homeowner never sees on the finished house:
- Removal of the old siding and gutters, about 5%. Tearing off and hauling away the old cladding is a job of its own, priced by area.
- House wrap and seam tape, about 5.5%. The weather barrier goes on the wall before any siding does. In this estimate it costs about a third as much as the siding boards.
- Scaffolding, site protection and permit handling, about 3%.
Flashing is not a separate line here. It sits inside window and door installation, together with sealing around the openings.
Together, removal, wrap and setup come to around 14% of this estimate. A quote that leaves them out looks cheaper, and it is also a quote for a different job. So the first question to ask about any siding quote is simple: is the tear-off in it, and is the wrap?
Time is part of the price
The estimate gives 21 days, and the reasoning behind the number matters as much as the number. The work runs in order: old siding comes off, the wall is wrapped, windows are fitted and flashed, siding goes on, then trim and foundation are painted. Paint on the foundation and trim needs 48 to 72 hours to dry, and those days cannot be squeezed out by adding people.
A schedule built only from labor hours comes out shorter than the real one. When a quote gives a duration, ask whether it counts from the first day of tear-off to the day the scaffolding leaves, drying time included.
Why two quotes for the same house differ
With the table in front of you, the usual reasons become visible:
- Different scope. One quote covers siding only. Another includes windows, the door, gutters and the porch. On this house those extras are more than half the estimate.
- Removal priced in, or assumed away. Some quotes treat the old siding as someone else's problem.
- Wrap and flashing named, or folded into "installation". If a quote does not name them, ask.
- Paint and trim. The fiber cement in this estimate comes prefinished, and trim, foundation and stairs still get their own painting line.
- The crew's rate. The same line, done by a local crew or by a specialist contractor with a warranty, carries two different prices.
Compare the lists of lines first. Compare the totals only once the lists match.
How it looks on a real house
Read the two frames as a list of work rather than a change of style. The siding stays close to the same shade. What appears is a porch with column wraps, a railing system, a roof, steps and a finished base. On the estimate above, the porch alone takes about 9%, more than twice the gutters with their installation.
This is why an estimate is worth building from a picture of the house you actually plan to change. A generic cost per square foot does not know you are adding a porch.
The order that saves the most
- Decide the look first. Half the lines in an estimate depend on what the finished house will have: a porch, new windows, a different trim color.
- List everything that changes, not only the wall. Gutters, windows, doors, railings, steps and foundation paint are all separate lines.
- Ask for tear-off, wrap and flashing by name. They are the lines a shorter quote can quietly leave out.
- Ask for the schedule with drying time. From first day of tear-off to the day the scaffolding leaves.
- Compare line lists before totals. Two totals only mean something when they price the same work.
