FAQs
What are the height and placement rules for a fence on my property line?
Londonderry zoning sets a 4-foot height limit for front yards and 6 feet for rear yards. The 0-foot setback regulation allows building directly on your line. For corner lots, you must maintain a clear 'sight triangle' for traffic safety, especially near high-speed corridors like I-93. Installing a solid fence in this triangle is a zoning violation.
Can I have a smart gate if I also have a pool?
Yes, but integration is critical. A smart gate system must mechanically comply with IBC 2021 Appendix AG for pools, requiring a self-closing mechanism and a latch at 54 inches minimum. The IoT controller must not override these physical safety features. Properly integrated systems meet modern liability standards for New Hampshire homeowners.
Am I legally required to tell my neighbor before I replace our shared fence?
Yes. Under New Hampshire's Good Neighbor Fence Law (NH RSA 476:1), you must provide written notice to adjoining property owners before altering a shared boundary fence in Londonderry. This 2026 legal requirement helps define cost-sharing and prevents disputes. Failure to notify can impact your ability to recover costs.
How soon can a consultant visit my property for an estimate?
A structural consultant can typically be dispatched within 48 hours. From our central reference point near Mack's Apples, the route via I-93 to most Londonderry Village locations allows for a 25-35 minute travel time. We schedule consultations to assess wind exposure, frost depth, and zoning compliance in a single site visit.
What fencing materials hold up best in Londonderry's soil?
Material compatibility is key. With moderate soil corrosivity and termite risk, pressure-treated wood with G90 galvanized or stainless steel fasteners is standard. Inferior fasteners cause rust streaks. Vinyl or composite materials are also suitable but require specific UV stabilizers. Avoid untreated wood in direct ground contact.
Is a standard 8-foot post spacing strong enough for our wind?
No. Londonderry's 115 MPH V-ult wind speed rating dictates engineering. For a solid-panel fence, 8-foot spacing often fails. ASCE 7-22 standards require closer post spacing (6 feet or less) and reinforced concrete footings with anchor brackets to resist peak storm season gusts, particularly in exposed areas.
What is required before digging fence post holes?
You must contact Dig Safe 811 at least three business days before excavation. Hitting a buried utility line in Londonderry Village is a major liability involving repair costs and fines. We manage the permit paperwork with the town, ensuring the plot plan and footing details meet current 2026 stormwater permeability requirements.
Why do so many fence posts in Londonderry Village heave out of the ground after winter?
The IRC requires footings below the local frost line to prevent frost heave. Londonderry's 48-inch frost line depth means any post set shallower will be lifted by expanding soil. Posts near Mack's Apples, with its open fields, are especially vulnerable. Proper concrete footings extending below 48 inches are non-negotiable for stability.
