The most critical concern while installing the ledger board should be how to prevent water from entering the seams into the building. Installing flashing known as a drip edge to act as a barrier to keep water out should be on every deck structure. If water can penetrate into the buildings framing it can result in structural issues, severe mold, decay, and overall serious and expensive damage.
Foundations consist of concrete poured over steel because concrete will naturally crack if given enough time. Even the strongest and most supported concrete foundation will eventually crack to some degree.
Moisture ants in Washington State and the risk they pose to building damage.
These ants thrive in damp environments and are attracted to wood that is decayed or damaged by moisture. Wood near bathtubs and areas damaged by water from plumbing leaks are popular nesting sites. Homes with outdoor access to attics and crawl spaces are at risk for infestations since moisture ant swarmers and workers may also enter through open doors or windows searching for sweets and a suitable moist habitat.
What the Heck is a Nailing Pattern?
For those who are uninitiated in the world of fasteners, a nailing pattern or fastener schedule is the national, state or regional building code allowances for fastening specific materials. There are hundreds of different nailing patterns for tons of building materials ranging from drywall to trusses and everything in between.

Facts about wood decay and decay fungi:
- According to Ohio State University, replacement materials needed to repair damage caused by decay account for nearly 10% of U.S. annual wood production.
- Carpenter ants, termites and other wood-destroying insects do not cause wood decay. These insects are, however, attracted to wood that has been softened by decay.
- Decay fungi are active in temperatures between 77° F to 90° F, and need water, oxygen and a food source to survive.
- Fungi that cause wood decay are called saprophytic, a term also applied to other organisms that consume decayed material. Many species of fungi, along with saprophytic beetles, worms, protists and bacteria are essential components of the decomposition and nutrient cycles.
