There are many different treatments or preservatives on the market today. some are effective on some species of wood, while not effective on others. The way the treatment is applied and the condition of the wood makes a big difference in how good the wood will ultimately be treated. Pressurized treating is by far the most popular. Some treatments are water-based and some oil-based. They each have particular advantages and disadvantages. The most popular treatments for Doug Fir is ACZA and ACQ which are water-based and Creosote and Penta which are oil-based.

There are lots of buzz words and phrases like “ground contact” and “treated to refusal” used in the marketplace that lead you to believe that you are looking at a quality treated product. Unfortunately, the unaware customer ends up paying in the end with premature product failure and high replacement costs.

We deal only with wood treating companies that follow AWPA (American Wood Preservers Association) guidelines to assure that our products are properly treated to the highest standards. Only by meeting these guidelines are you guaranteed that you will get the longest lasting wood available.

It may cost more for our product initially, however, when you look at the yearly cost spread over the first 10 to 20 years (after most posts have failed) it pays to go with Doug Fir. If you look at the cost over 40+ years (the usable lifespan) you will see that your cost is considerably less.
