What Are Main Causes of Trim Rot?

Understanding Wood Trim Rot Causes

No matter what type of material the exterior of a home is, most commonly there is a trim. They also are typically made of wood.  Over time these areas of wood trim can rot and break down. While it may seem this would be a surface issue, rot on trim can actually affect some of the structure balances in a home.

Wood trim along doorways, windows, garages, and entryways can rot and cause cracking of the walls around the trim area as the wood begins to disintegrate.

This can cause more long-term problems for a homeowner because in addition to repairing the rot, you may find yourselves repairing the walls around the rot as well.

Primary Causes of Trim Rot

In general, there are usually three causes of trim rot on a home. They are weather, dry air and insect infestation. No matter what the cause is, it is advisable to tend to any wood trim rot as soon as it is noticed to avoid having any increased problems from arising.

Weather Trim Rot

If a window or door casing tends to have a water pooling problem, over time this will cause the wood to rot. Wood is not shielded from the effects of water damage. Just as tree trunks can rot in standing water, so can wood trim on a doorway or window if left with a constant exposure to a water leak situation.

Dry Air Rot

Wood that is not pressure treated properly has a better chance of being affected by arid conditions. Overly dry air and extreme sun can cause wood trim rot. Rot from high sun exposure is usually found when the wood trim on doorways or windows when there is extensive sun exposure on a daily basis over years of time.

Insect Infestation

This is actually a quite common problem no matter what the home’s exterior is. Wood boring insects can cause extensive damage to wood trim and sills.
