You might be surprised how much dirt and mildew can accumulate on a deck during the winter months, and you should get in the habit of cleaning it routinely to preserve the quality and life of the deck. To clean a deck, you can either pay a cleaning service or rent or buy a pressure washer and do it yourself.
You'll pay a cleaning service $165 to clean a 15-foot-by-20-foot (approximately 300 square feet) one-level deck. You can rent a pressure washer for the afternoon for $80 or buy an electric pressure washer with a pressure range of 1500-2000 PSI (pounds per square inch) for about $175 and do the job. No matter who does the work, you should take the time to inspect the deck looking for loose fasteners and split or damaged boards, and repair them. For added protection, apply a water sealer, which runs about $30 for two gallons and is best applied with a paint/stain pad on an extension pole.
The payback on the investment in the washer isn't immediate, but if you're looking for a good excuse to buy one, this is it. We use ours to clean the deck, the siding, the shed and picnic table and even our boat, and it's been on loan for countless other uses.
