Peterson's Contracting - Derry's Top-Rated Residential Fencing

The primary cause is the region's clay-heavy soil mixed with freeze-thaw cycles and frequent winds. Rain saturates the ground, then freezing expands the soil, pushing posts out of alignment. Our solution goes beyond standard installation: we dig deeper than the frost line, typically 36 inches, and use quick-drying concrete that stabilizes the post securely. We also recommend pressure-treated lumber or metal posts that resist rot and corrosion, ensuring your fence stays upright through Derry's seasonal changes.

Yes, it's very common here, especially on gates that experience strong gusts from open fields or near Chestnut Ridge. The sign is often a gap between the gate and latch, or scraping on the ground. We solve this by replacing hinges with heavy-duty strap hinges that distribute weight better, and adding a wheel or anti-sag kit if needed. We also check the gate frame for warping and can install a corner brace to keep it square. You'll get smooth operation even with the occasional Derry windstorm.

For homes near the Norfolk Southern line, we recommend a solid privacy fence, typically 6-foot vinyl or cedar, with overlapping boards to block sound and sight. The key is ensuring it's set deep and with reinforced corners to handle the vibration and wind. We also add a bit of space at the bottom (with a gravel strip) for drainage, since the soil there can be compacted. This gives you a quiet, private yard without the constant noise from the trains passing through Derry.
