No, it’s not too expensive. A cedar deck builder in Kirkland, WA will recommend maintenance at least once a year to extend their life span. Frequent moisture, freezing, and wet weather conditions will age your cedar—which is why you need the annual maintenance. Every autumn, take some time to get your deck washed. You can do it yourself or you can hire someone to do it. In addition to the annual washing, we recommend that you also reseal it every other year.
