Moreno Landscaping | Trusted Fence Installation in Livermore, CA

The main cause is our local soil composition—clay-heavy soil that expands when wet in winter and contracts in the dry summer. This movement, combined with water runoff, erodes the ground around posts. At Moreno Landscaping, we solve this by setting posts in concrete with drainage gravel at the base, and we can reinforce existing wobbly posts with a concrete collar to stabilize them.

A common early sign is when fence boards begin to cup, curl at the edges, or pull loose from their nails. You might also notice gaps between pickets that weren't there before. The sun's UV rays and dry conditions here cause the wood to shrink and twist. Our solution is to install properly treated, kiln-dried wood with spacing that allows for expansion, and we recommend a quality sealant to protect against future warping.

Absolutely. If the posts are still sound but the soil has washed out around them, we can add compacted gravel or install a small retaining wall feature along the fence line to redirect water flow and prevent further erosion. For severe cases, we may replace a few critical posts with deeper footings, saving you the cost of a full fence replacement.
