How to Bid on a Siding Job

by Gracie Sprouse - Updated September 26, 2017
Bid forms should include all aspects of the work to be done.

For a contractor, submitting the bid for a job is almost as important as doing the work. There are standard contractor bid proposal forms that can be purchased from office supply stores and home improvement stores, including Office Depot, Staples, Home Depot and Lowes. All aspects of the work that is going to be performed must be outlined on the proposal form. Only the work outlined is to be completed; if the client wants something different done, an additional form must be completed.

Fill in the name, address and other information for the person who is receiving the bid. Enter the address where the work will be performed.

Complete the information for the name of the architect if there is one, and the date the plans were created.

Explain in complete detail exactly what work will be performed in the third section of the form. This includes describing the type of siding (including the colors, brand and model number) and a description of the building.

Indicate the materials that you will purchase to complete the siding job.

List the timeline for the work to be done. Show the start date and the estimated ending date.

Write in payment terms between the customer and the contractor. This is usually shown as 50 percent down and the balance upon completion.

Sign the form and indicate the number of days you will wait to receive their acceptance of the bid. Since the cost of materials and labor can change, the bid proposal should have a future date after which the bid becomes invalid.


  • Contractors need to have an excellent understanding of the building trade to properly prepare a bid. The current cost of materials must also be checked, as these can fluctuate. A contractor could lose money on a job if he does not correctly estimate his costs.
