Pressure Treated Deck Washing, Cleaning, Stripping & Sealing, Repairs in MD, VA



Many homeowners with pressure treated deck structures have wood that contains a compound known as Chromate Copper Arsenate, CCA for short. Many decks built with pressure treated lumber contain CCA (arsenic) which has been found by the EPA to be a health hazard. Pressure treated deck washing services are an important part of maintaining your investment, but they need to be done properly. Properly cleaning and sealing decks, screened in porches, gazebos, fences, playsets, sheds, and other wooden structures helps to protect consumers against exposure to CCA. While the purpose of this treatment was well intended, the result was potentially toxic to those who would come into contact with it more than just occasionally.

The EPA’s December 12, 2001 report on this subject reads in part: “… Results of these studies as a whole support that surface coatings (applied after CCA treatment) are effective at reducing the quantities of dislogeable and leachable arsenic. Reductions of 70% to 90% in dislogeable arsenic were observed across the studies as CCA treated wood was subjected to natural weathering.”

What types of coatings are most effective? While available data are very limited, some studies suggest that applying certain penetrating coatings (e.g., oil-based, semi-transparent stains) on a regular basis (e.g., once per year or every other year depending upon wear and weathering) may reduce the migration of wood preservative chemicals from CCA-treated wood. Having your deck properly cared for using low pressure treated deck washing and sealed on a regular maintenance schedule is the best way to protect your investment in your deck, fence, screened in porch, gazebo, playset, furniture or shed.

In selecting a finish, consumers should be aware that, in some cases, “film-forming” or non-penetrating stains (latex semitransparent, latex opaque, and oil-based opaque stains) on outdoor surfaces such as decks and fences are not recommended, as subsequent peeling and flaking may ultimately have an impact on durability as well as exposure to the preservatives in the wood. Consumers also need to be aware of the VOC changes that went into effect in 2005. These changes have had an impact on the coatings industry, and on product performance.

Two of the most popular relatively new pressure treatments are ACQ-Alkaline Copper Quat, and CA-B copper azole, which contain fungicides and insecticides. Both ACQ and CA-B meet the requirements for wood that comes into ground contact, and provides protection from potential insect infestation.

Other types of new wood pressure treatments are available, but aren’t as widely produced. Pressure treated deck washing is important for all types of pressure treated lumber, to remove, mildew and algae growth. To find out which type your deck may have been built with, ask a See Dirt Run!™ Inc. representative when receiving an estimate for your maintenance needs.
