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

What to spell out on a patio slider replacement bid

  • Full frame, and why: the flashing and sill pan are new.
  • Trim inside and out, replaced and painted, or reused.
  • Operating panel on the left or the right, viewed from outside.
  • Lead time from the deposit.

Lead times on custom windows are long and the deposit is what starts the clock. Say that on the bid so nobody is surprised at week six.
