How to Estimate Vinyl Siding Costs for New Construction and Re-siding
Vinyl siding estimates go wrong in a predictable place: contractors measure the walls, price the siding panels, and leave money on the table because they forgot the accessories. Starter strips, J-channel, corner posts, undersill trim, and drip cap can add 25–40% to the material cost of a job - and they're invisible in a fast takeoff because they don't show up in square footage. You price 2,000 square feet of premium siding and discover on delivery day that you're short $1,800 in trim pieces you never quoted.
