Dry Rot Repair Contractor Lafayette, CA

In scenic Lafayette, where mature trees and seasonal moisture are part of the charm, dry rot can quietly creep into old and new homes. All it takes is the combination of wood, moisture, and warmth for dry rot to develop. Over time, the wood begins to shrink, darken, crack, and soften, potentially leading to serious structural issues. Exterior trim is usually the first area to show signs of damage and can deteriorate quickly if left untreated.

Fortunately, dry rot in trim is typically easy to repair. But the repairs can become much more involved when it spreads to key structural areas like mud sills or framing. Dry rot only affects damp wood—generally with a moisture content of over 20% %—so the first step is always identifying and addressing the source of that moisture.

In Lafayette homes, interior sources like leaky showers, sinks, dishwashers, or washing machines are common culprits. Outside, water often seeps in through cracks in siding or stucco, damaged roofing, or poorly sealed windows and doors. Once the moisture source is eliminated, drying out the affected area is essential to stop the rot from spreading.

After proper drying, all damaged wood should be removed and replaced with pressure-treated or pre-treated lumber. Ensuring the correct installation of trim, framing, and metal flashing is key to preventing future water intrusion. To finish the job right, any vulnerable remaining wood should be treated with a high-quality fungicide to prevent the return of rot.
