Diyarza Landscaping: Best Commercial Fencing Serving Brooklyn, NY 11218

Frost heave is the main culprit. As temperatures drop below freezing, water in the soil expands, pushing fence posts upward and sideways. This is common in Brooklyn’s clay-heavy soils. If posts aren’t set below the frost line (~36 inches) or lack proper drainage, they’ll shift after a few freeze-thaw cycles.

Look for orange or white rust on hinges, latches, or brackets. In coastal Brooklyn neighborhoods (like Red Hook or Coney Island), salt air speeds up corrosion. Also, check for stiff, squeaky gates or loose screws that won’t tighten—these are signs the metal has weakened and may soon fail.

We install posts with concrete footings extending below the frost line and use gravel bases for drainage to resist frost heave. For hardware, we use galvanized or stainless-steel components. We also offer adjustments to existing fences, such as adding post braces or replacing corroded hinges, to extend your fence’s life.
