Example figures for a typical railing replacement job. Not a quote. Every line on the estimate came from the notes above. Nothing was added.

What to spell out on a railing replacement bid

  • Linear feet, height, and the product and color.
  • Post count and how they are mounted, with blocking in the frame.
  • Gates, by count, with latches.
  • Stairs, both sides or one, and that the code height is met.

Composite versus wood changes the price by thousands. Put both as packages on one bid when the customer is undecided, and say what the railing is.
