Wood Treatment Services


The longevity of quality lumber starts with good, well cared-for logs. Protect your timber and other construction components from pests, cracks, checks, water abrasion and fire damage. Choosing the right treatment to go on your timbers can make the life of them go for 1-2 years to 10-20 years depending on the final use. All of our treatment options are done to order, so you can get exactly what you need and can leave out what you don't. We treat everything from crane mats to wedges.

Incising & Staining

Incising hard-to-treat species such as Douglas Fir, provides the depth of penetration that is necessary to adequately provide a proper treatment. Treatment stains are available in a variety of colors and can stand out or blend with your landscape. Call to go over your custom treatment options today.
