Green Mountain Landscaping: Local Fence Contractors Serving San Bruno, CA 94066

In San Bruno, the most common cause is soil shifting from minor earthquakes or seasonal moisture changes. The ground can soften, causing fence posts to tilt. Additionally, strong winds near the Bay can push against older fences, accelerating leaning.

Signs include posts that are no longer vertical, gaps between fence panels, cracks in concrete footings, or nails and screws that have popped out. If your fence looks uneven or sags, it may have been affected by seismic activity.

We recommend a thorough inspection first. For minor leans, we re-set the posts with additional concrete and bracing. For major damage, we replace rotted or broken posts with stronger materials and use flexible connectors to allow movement without collapse during future quakes.
