Reliable Fencing Company in Oswego, IL 60543 - J&L Services

In Oswego, frost heave is the primary cause. During freeze-thaw cycles, moisture in the soil expands, pushing posts upward or sideways. If posts aren't set deep enough (below the frost line, roughly 42 inches here) or drainage is poor, movement is nearly guaranteed. We can reset posts to the proper depth and add gravel drainage to minimize future frost heave.

Look for soft, spongy wood at ground level or a greenish tint, which indicates moisture damage. In Oswego's humid summers and wet springs, ground-contact posts rot faster if not treated or set in concrete or gravel. The solution is to replace the affected posts with pressure-treated or rot-resistant materials and ensure the base stays dry.

Yes. We handle deck construction, repair, and replacement in Oswego. Often, homeowners with fence issues also need deck work—like replacing rotted boards or reinforcing railings. We can combine a fence post replacement with a deck inspection to address both structures, saving you time and coordinating the look of your outdoor space.
