Specialty Contracting: Local Privacy Fence Installation Serving Derry, NH 3038

In Derry, the main cause is frost heave—the soil expands and contracts with freezing and thawing. This can shift posts, especially if they weren’t set deep enough. Moisture from snow and rain also leads to rot at the base. Signs include a visible tilt, loose gate, or wood decay. Our solution is to replace the post with a concrete-reinforced footing set below the frost line, ensuring stability year-round.

Look for signs like cracked or splintered boards, wobbly railings, or rusted fasteners. If only a few boards or railings are damaged, repair is often sufficient. However, if the ledger board (attached to your house) is rotted or the posts are sinking, a full replacement may be safer. We’ll inspect your deck and give you honest advice—repair if possible, replace only when necessary to keep your family safe.

Absolutely. Sagging gates are common in Derry due to frost heave and heavy snow. We use heavy-duty hinges, a diagonal brace, and set the posts in concrete. For gates that need to open over uneven ground, we can install a custom drop-rod or a tension cable. This keeps your gate swinging smoothly and closing tight, even after winter.
