Henrys Quality Underlayment | Expert Fencing Company in Hillsboro, OR

The primary cause is the constant exposure to moisture from rain and damp soil in our area. Over time, water seeps into untreated or poorly sealed wood, leading to fungal decay and rot. This is especially common in neighborhoods like Orenco Station and Tanasbourne where clay-heavy soils retain water.

Look for visible cracks, soft or spongy wood near the base, leaning sections, or mushrooms growing around the post. If your gate sags or the fence wobbles when pushed, it's likely a sign that the post has rotted underground. Catching it early saves you from a full replacement.

We typically replace the affected post with a pressure-treated or rot-resistant wood like cedar, set in a concrete base with proper drainage. For metal posts, we ensure they are galvanized and installed above the soil line to prevent moisture wicking. Our goal is a long-lasting repair that withstands Hillsboro's wet winters.
