Privacy Fence Installation Palmer AK | Call Kopplin Kustoms Fabrication and Repairs

The main cause is frost heave, where water in the soil freezes and expands, pushing posts upward. In Palmer’s silty soils, this is very common. We prevent shifting by digging post holes below the frost line, adding 6–8 inches of gravel for drainage, and using concrete collars or helical anchors. These measures keep posts stable even during the spring thaw.

Yes, it’s a classic sign. When posts heave unevenly, the rails attached to them separate or break. We repair this by first realigning the posts (adjusting or resetting them), then reinforcing the joints with sturdy metal brackets or replacing damaged rails. If the heaving is recurring, we may recommend deeper footings or a different post-setting method.

We offer weatherproofing services using exterior-grade stains and sealants that resist moisture, UV, and temperature swings. For metal gates, we recommend a rust-inhibiting primer and powder-coat finish. For wood, we apply a penetrating oil-based stain that flexes with the wood. Proper sealing and annual inspection of joints and hinges will extend the life of your fence or gate significantly.
