Your counter list
The items siding contractors buy every week, from the van stock on our tools list. Ask each supplier for a price on these first; they decide which account saves you the most.
| Item | Why it is on the list |
|---|---|
| Siding nails and trim screws | The right length for the panel |
| House wrap and seam tape | Water barrier repairs |
| Trim coil in your common colors | Wraps and small fixes |
| J channel, starter strip and corners | The pieces every wall needs |
| Sealant matched to siding colors | Finishing around fixtures |
| Spare panels in the colors you install most | Storm and damage repairs |
For the first order, price the starter kit too: extension ladder and ladder jacks or pump jacks; multi-position ladder; siding nailer and a compressor; aviation snips, left and right; siding removal tool (zip tool); snap lock punch and nail slot punch; circular saw with a fine-tooth blade; chalk line and a 4 ft level; utility knife, hammer and pry bar. Bigger purchases to price at a dealer or rental house: portable aluminum brake; fiber cement shears or a dust-collecting saw; pump jack system with planks; dump trailer; moisture meter.
Opening a trade account
Bring your business name, tax ID and license number, and a credit application if you want terms. The big-box programs are compared row by row on Home Depot Pro vs Lowe's Pro. For the tools themselves, the siding tools list has prices read on the makers' own sites (Little Giant, Delmhorst).
When supplier prices change
Update your siding price list the same week a supplier raises prices. In Koira, that price list is what your estimates are built from.
