The average is between 2.00 and 2.50 a square foot. This includes powerwashing, detergent, and stain. Also, this is for your basic spindles on the railing.

Depends on how professionally you want it done. My company PressurePros, inc specializes in deck restoration. We apply a cleaning agent that emulsifies old stain, kills mold and softens grayed wood to allow us to use very low pressure to wash. After the deck is completely washed we follow with a pH balancing neutralizing agent. That gives the stain better bond and gives you an even finish. We then sand all handrails before applying two coats of tinted oil based, VOC compliant sealer.
Handrails will account for 6 s.f per linear foot of measurement. A 10x10 deck would be 100 s.f on the floor plus 210 s.f of rail. That does not include stairs or add-ons like trellises, planter boxes and benches. Our price is $1.60-$2.00 per s.f.

Most products like deck sealer will tell you on the can how many square feet it will cover.
The location of painting the exterior of a home isn't going to make a difference as far as cost. But to calculate how much you can anticipate spending to paint the outside of your home you take the cost of a gallon of paint you wish to purchase (different colors will cost different amounts, anywhere from twenty five dollars a gallon to forty a gallon) and multiply that number by the square footage that needs to be covered by paint divided 350 which is how much square footage a gallon will cover. So the final formula would look like this: CostPerGallon * (SquareFootage / 350) = TotalCost And then add in the labor which should be about two to three times the paint cost depending on the complexity of the job.
Yes.
Can you put stain in polyurethane to darken the color?
Paint covers a surface with a protective film, and stain will penetrate through the wood. Stains are generally considered to be lower maintenance than paint, so stain is a better choice for a deck.
