Wood Rot

06 Apr Wood Rot

Have you checked your home’s exterior for wood rot recently? Do you know how to check for it and what to do if you find it? Unless you have previous experience and good knowledge of wood rot, leaving it to reputable paint professionals to detect and address this insidious problem is probably best. In Northern Virginia, spring is the perfect time to check for wood rot.

What is Wood Rot and What Causes It?

Wood rot is the deterioration and decay caused by a particular fungus which attacks the part of the wood which binds it and gives it strength. With enough time, the wood crumbles and can no longer function with strength or integrity. If the wood is part of your home, the effects of that decay can be serious.  If left unchecked, the damage of rot can range into the thousands if not tens of thousands.

There are four conditions necessary for wood rot to occur:

1. Wood
2. Oxygen
3. Warmth
4. Moisture

Preventing Wood Rot:

There are four steps you can take to prevent wood rot:

1. Keep your house well painted. The paint creates a barrier and protects those areas vulnerable to fungi and moisture.
2. Avoid standing water. If water pools by any wood, then it’s more likely to begin seeping into joints and cracks leading to rot. Inspect your home several times a year, especially after heavy rains, to ensure there’s no standing water touching wood on your home’s exterior.
3. Air circulation is important. It allows the wood to dry out faster when it does become moist. Make certain shrub and trees are cut back several feet from touching any part of your house so that there is good airflow.

Detection:

It isn’t always easy to detect wood rot. Like termite damage, it can start where it’s not visible to the naked eye and work its way to becoming more apparent. By then, the serious damage has begun. A trained professional knows to look for certain evidence that wood rot is present.  Lastly, it is important to properly treat and correct the area to avoid it becoming infected again.  

Spring is a good time to check your home’s exterior for any wood rot before summer’s humidity and moisture set in.  Contact us, if you’d like to schedule a wood rot inspection of your home and a free estimate.

FAQ

1. What is wood rot and what causes it in homes?

Wood rot is a form of decay in wood caused by fungi that thrive in moist conditions. For wood rot to develop, it requires oxygen, the right temperature, and moisture. These conditions allow wood-eating fungi to break down healthy wood fibers, often leading to rapid deterioration if not addressed.

2. Where is wood rot most commonly found around the house?

Wood rot most frequently occurs in areas exposed to moisture, such as exterior trim, siding, window sills, doors, decks, railings, soffits, and even basements or crawl spaces. Poorly sealed windows, cracks around doors, and any wooden surfaces near the ground are especially vulnerable.

3. How can I identify signs of wood rot before painting?

Common signs of wood rot include wood that feels soft, spongy, brittle, or crumbling; damaged or peeling paint; powdery residue; mold growth; and a musty odor. It is important to inspect all exposed wood surfaces regularly, especially before starting any painting project.

4. Should I paint over wood rot or does it need to be repaired first?

Painting over wood rot is not recommended. The paint will not adhere properly to rotted wood, leading to cracking, bubbling, and premature paint failure. Additionally, the underlying rot will continue to spread, potentially causing structural damage and attracting pests. All rotted wood should be repaired or replaced before painting for long-lasting results.

5. What steps can I take to prevent wood rot in the future?

To prevent wood rot, ensure all exterior wood is properly sealed with paint or stain, and keep up with regular maintenance. Inspect caulking and painted surfaces annually for signs of wear or failure, and address any issues promptly. Keeping wood surfaces dry and well-protected from moisture is the most effective way to avoid rot.
