Wood Siding and Trim
Cedar shingles, horizontal lap siding, logs and textured plywood are all common types of wood siding. Trim boards are usually made from kiln dried redwood or cedar. These are the most rot and insect resistant of the woods and perfect for exterior applications
Wood siding is considered a durable, natural material. Painting or staining is required on a regular basis to protect it from weather damage and to achieve its full expected life.
Minor visible imperfections are normal in wood siding material and not considered a defect. Painted trim boards should be knot free.
Extreme temperature changes can cause expansion and contraction cracks that may be necessary to correct. If cracks or joints appear that may allow water to enter the framing of the home they should be immediately caulked and repaired.
In general, if exterior trim or siding materials are split wider than 1/8 of an inch they should be repaired. Use caulking and touch-up paint. Siding or exterior trim material with bows or twists that exceed 3/8 inch in 8 feet should be refastened or replaced. Exterior trim board cupping exceeding 3/16 inch in 5 1/2 inches should also be repaired or replaced.
- Note any obvious cracks, joint separations. Warps or twists in the wood siding and trim and plan to make repairs.
