LG Fence | Fence Installation & Repair in Greenbelt, MD

The main cause is the area’s high humidity and clay-rich soil that retains moisture. In Greenbelt, especially near low-lying spots like the Greenbelt Lake area, water can pool around post bases. Over time, this leads to rot, especially if the wood isn’t pressure-treated or if the posts are set directly in concrete without gravel for drainage.

Look for soft or spongy wood near the ground, discoloration, or a musty smell. Check if the fence leans or if the gate sags. In Greenbelt’s freeze-thaw cycles, cracked or splintered posts are early signs. You can also probe the base with a screwdriver—if it sinks in easily, rot has set in.

LG Fence recommends replacing affected posts with pressure-treated wood set on a gravel base for drainage, or switching to vinyl or aluminum which don’t rot. For existing fences, we can install post supports or concrete footings above ground level. We also advise grading the soil away from the fence line to reduce moisture contact.
