I Recommend That You Break Bids Down
When pricing wood restoration, you hear all kinds of numbers that don't seem to jive. Here are some simple guidelines I used to get several hundred jobs each season:
Price the floor by square foot - usually around $1.25 in our area (including materials and labor)
Price the railings by square foot or running foot: usually around $1.25 per square foot or $7.50 per running foot (there are 6 square feet per running foot when you think about both sides).
About $18.75 per step, including the railing on each side of the step).
By pricing this way, you automatically compensate for the differences between bidding large decks vs. small ones. At these bid prices, that deck would have come in closer to $900 to $1000.
For fencing, which is seldom judged as critically as a deck, I tended to stretch the sealer a little and not be quite as fussy on the wash. In addition, since there were no ladders involved in the work and very little protection/prevention steps necessary (and lots of square feet per job) I dropped my prices down for fences to the 60-cent range per square foot. A 310' privacy fence has 3720 sq ft. which I would have bid at $2232.
When trying to figure out your bidding plan, consider this. In the wood restoration business, the products are your key. They determine the speed you can work at and the kind of results that you will get. I used products (sealer, stripper/cleaner, brightener) that end up costing around 24 cents per square foot to buy and use (including an allowance for freight costs). If your materials run 24 cents, and you want to keep your material cost percentage at around the 20% range, then you have to charge around $1.20 per square foot. Remember that you are being paid as much for what you know as what you do in Wood Restoration. Charge accordingly.
When you read numbers like $2 per square foot, these nubers include a factor for the railing along with the floor. The problem with using a number like that is that a 100 sq ft deck (10 x 10) has 30' of railing while a 200 sq ft deck (10 x 20) only has 40' of railing. The ratio of railing to floor changes dramatically from deck to deck. Smaller decks tend to run higher per-sq-ft that larger decks for this reason only. Breaking the bid process into small pieces (floor, rails, steps) gives you better results in bidding.
NOTE: On the fence portion, your materials may only cost you 20 cents per sq ft, but your percentage Cost Of Goods is closer to 33% than 20%. Dangerously high, caused by charging too little. I figured that I saved so much time doing the fence that everything would balance out.
Of course I left out all of the subtle details like PITA factors. I always charged more for height, lousy access, fish ponds nearby, a retired homeowner who would likely be stopping me and asking questions all day, etc.
Good luck in your career!
