Job costing for siding and gutter contractors
Siding jobs are bid by the square, but the trim, flashing, and wall surprises under the old siding are what decide whether the job pays. JobMargin keeps siding, trim, and gutters on separate lines and shows labor against progress while the crew is still on the house.
What siding and gutter contractors track in JobMargin
- Siding, trim, and gutters separately. Each gets its own budget, so a trim-heavy house doesn’t look fine until the last day.
- Tear-off and disposal. Dumpster swaps and dump fees post to the job, so you learn what tear-off really costs per square.
- Quotes homeowners accept online. Send a private link; the homeowner types their name and taps Accept, and the bid turns Won.
- Rot and repairs as change orders. Sheathing repair found under the old siding goes in as a change order, with photos in the daily log.

Bid line items use the units siding actually bid in: squares (SQ), square feet (SF), linear feet (LF), each (EA), and lump sum (LS).
Example: what a siding job looks like mid-way
Tear off vinyl, then install 32 squares of fiber cement, new trim, and 280 linear feet of seamless gutter on a two-story home. The siding is about 75% hung; gutters go on last.
| Cost category | Budget | Spent so far |
|---|---|---|
| Siding Materials | $15,500 | $15,200 |
| Labor | $14,000 | $11,800 |
| Trim & Flashing | $3,800 | $2,900 |
| Gutter & Downspout | $2,600 | $0 |
| Disposal | $1,200 | $1,050 |
| Equipment Rental | $1,000 | $800 |
| Other | $800 | $150 |
| Total | $38,900 | $31,900 |
The siding was delivered all at once, so 98% spent there is expected. Labor is the warning: 84% spent with the siding about 75% hung and the gutters still to go. At this pace, siding labor alone finishes around $15,700 against a $14,000 budget, before the gutters go on.
