Handyman's Tip - #1 {Pressure Treated Lumber for Decks}

A popular trend in deck building - especially for do-it-yourself-ers, is the use of "pressure treated wood". It is often the first choice for a variety of reasons, it's inexpensive - both upfront and in the future because of it's extremely long life span. It retains a new appearance for years, often with as little maintenance as an annual pressure wash. Finally, it is easily accessible and comes in all the same sizes as standard dimensional lumber. 


So what, you ask, is the problem? This product sounds like a miracle!


The problem is this, prior to 2003 all pressure treated lumber was manufactured using CCA (chromated copper arsenate). The presence of this chemical has been proven not to reduce in toxicity over time, and I always recommend that when children are involved, all pressure treated decks and floor space be replaced. After 2003, the dangerous chemical was replaced with other, less toxic chemicals and copper based pesticides, however for my family, I wouldn't take the risk. 


Wikipedia shares a similar explanation:
"On December 31, 2003, the US wood treatment industry stopped treating residential lumber with arsenic and chromium (chromated copper arsenate, or CCA). This was a voluntary agreement with the United States Environmental Protection Agency. CCA was replaced by copper based pesticides, with exceptions for certain industrial uses. During the Industrial Revolution wood preservation became a corner stone of the wood processing industry. Inventors and scientists such as Bethell, Boucherie, Burnett and Kyan made historic developments in wood preservation, with the preservative solutions and processes. Commercial pressure treatment began in the latter half of the 19th century with the protection of railroad crossties using creosote. Treated wood was used primarily for industrial, agricultural, and utility applications, where it is still used, until its use grew considerably (at least in the United States) in the 1970s as homeowners began building decks and backyard projects."

Pressure treated lumber, comes in a variety of stains and finishes, and looks similar to standard lumber. Make sure to read the tags! Or speak to the salesperson at your local Sleggs, Rona or Home Building Centre.

My recommendation for outdoor decking is Cedar, for it's natural ability to preserve itself. While more expensive upfront, a few simple design modifications can aid in it's preservation, such as aeration and drainage in wet climates. It simply can't be beat for it's distinctive look and feel, it's weathered appearance after several years can be chalked up to "character", and you will never have to worry about the potential negative health effects on children and pets, or yourself during hot barefoot summers. A little maintenance every few years, such as pressure washing and staining will only aid to it's life and appearance, however it can be done at your discretion. 

Beautiful cedar, natural and long lasting, always adds a rich look and feel.

Thanks for reading, and if deck building isn't your forte, I also recommend calling a local contractor for advise and/or assistance.
