G & G Tree Expert: Expert Fencing Company Serving Fort Washington, MD 20744

The main cause is the area's high humidity and proximity to water, like the Potomac River. Many homes in Fort Washington have clay-heavy soil that holds moisture against the wood. Over time, this constant dampness leads to fungal rot, especially at the ground level where the post meets the soil.

Look for signs like leaning sections, cracked or splintered wood, and soft, spongy spots near the base of the posts. If you see mushrooms growing on the wood or notice the fence wobbles when pushed, the posts are likely rotted. A quick inspection by our team can confirm whether a simple repair or full replacement is needed.

The most effective solution is using pressure-treated lumber and ensuring proper installation. We set posts in gravel at the bottom of the hole for drainage, rather than concrete, which traps moisture. We also recommend weatherproofing the wood with a high-quality sealant every two to three years. For automatic gates, we use galvanized hardware to resist rust.
