1 Cleaning is often done in conjunction with sealing or staining the deck. 2  Hiring someone to clean and seal a deck can cost $1-$5 a square foot ($320-$1,600 for 16'x20'. 3  Having someone clean and stain a deck typically costs $0.50-$7 or more a square foot ($160-$2,240 for 16'x20').
On average most deck stains cover 150-300 sq. ft. per gallon depending on the age, condition, and porosity of the wood. To figure how much deck stain you should buy, start by measuring the deck floor. Take its width times length and write that number down. Besides the main deck floor, be sure to add in any smaller decking areas like a second tier deck or stair landing platforms.
