Decking is typically measure and estimated based upon the square feet of deck that needs to be built or replaced.
Start by measuring the length and width of the deck to calculate the square footage. If your deck is not a perfect square or rectangle, break the deck down into small sections and then add each additional section together to calculate a total square footage.
To estimate your budget for your decking you will multiply your Total Decking Square Footage by your budgeted costs per SF pricing based upon the type of decking material used.
A decking crew can typically complete a 10x10 (100 sf) deck in 3 to 5 days. The first day will typically be used to layout the deck and dig and pour the concrete footers. On the second day the contractor will install the deck beams and joists and start installing decking. On the 3rd day the
Deck contractors will generally provide an all inclusive bid to 'furnish and install' all labor and materials on the project.
