FAQs – and answers – about wood rot in your home’s exterior
Unlike a hurricane or some other natural disaster, wood rot isn’t a scene stealer. But if left unchecked, rot could slowly – and silently – be compromising the integrity of the wood in your home. Fortunately, wood rot can be controlled if detected early and treated effectively.
What causes rotten wood?
If wood is untreated, moisture is the #1 enemy. If a porous wood surface comes in contact with enough water for enough time, the result is usually some kind of deterioration. This could be caused by leaks, flooding or excessive rain or snow.
What is the difference between wet rot and dry rot?
As the name indicates, wet rot (also called white rot) occurs when water permeates untreated wood. As the moisture seeps from the outside in, the wood becomes weak. Dry rot (also called brown rot) is a fungus that also starts with moisture, but can live and grow inside the wood even after it’s “dried out.”
What is the difference between rot and mold?
Mold is related to rot, in that it is fungi that grow from moisture. While there are health risks associated with a mold problem, mold doesn’t directly cause wood decay.
What areas are especially prone to rot?
The exterior of your home is especially prone to rot because of t’s exposure to the elements. Places to keep an eye on include:
- Window sills
- Trim around doors and windows
- Exterior wooden doors (including garage doors)
- Decking, including posts and railings
- Roofs and eaves
- Areas around gutters and downspouts
How do I check my home for rot?
It’s a good idea to check your home for rot every few months, especially if you live in a coastal area like Cape Cod. Rot can often be detected just by looking at and touching the wood. A discoloration or spongy feel unually indicates wet rot. If areas of the wood are split across the grain into cube-like sections, you probably have dry rot.
