Wood rot, also referred to as the cancer of homes with wooden siding or trim, can destroy a beautiful wooden structure quickly. Siding, soffits, railings and more can be affected by rain and water pooling against them causing damage. Is the exterior of your home rotting? Professional exterior wood home repairs might be in order.

Whether the water comes from rain and snow melting or failing paint and caulking, the outcome remains: rotten wood. Addressing the issue quickly will save you time and heartache.
Because water damage on wood can spread quickly, it requires immediate attention. If left untreated rotting wood could impact the structural integrity of your home.


So what causes rotting wood?

Moisture lingering on wood will ultimately cause the fibers of the wood to deteriorate. Unprotected wood, or wood with imperfections in the protective coating is susceptible to rot.


How do I find rotten wood?

To find spots of rotting wood, get a screwdriver and start inspecting the boards on the exterior of your home. Start by checking boards lowest to the ground and along your roof line. Also, check the seams where two boards meet. Most rot is visible in plain site, but often will be hidden. Remember that as you inspect, wood should never be soft when pressed. Use the tip of a screwdriver to press into questionable areas. If it gives, you should repair. Cracks that appear to be folding in are a clear sign of rot.


What are the most common carpentry repairs for wood rot?

Trim boards that have chipping paint and loose caulking are the most common place to find rot. Typically these will be cedar boards or LP SmartSide trim boards. These are the most common trim building materials here in Indianapolis. With cedar you will see splitting and deterioration, with LP trim you’ll see the board getting thicker from the moisture intake. Homeowners who do not repaint their exterior regularly are likely to discover these trim rot issues.

If you notice discoloration, flaking or chipping of wood, or punctures in trim , it is a good idea to perform carpentry repairs and replace the wood. Make it a habit to inspect the exterior of your home once or twice a year to check for these types of problems.
