Your details go to New England Garage Door Pros only, so we can reply. We would share them with a contractor only if one becomes available for your area and you agree. Privacy

How your request is handled: it comes to New England Garage Door Pros. We review it and reply by the next business day. No participating garage door company covers this area yet, so we can't promise a contractor introduction. If a spring or cable has snapped or the door is hanging crooked, leave it closed or open as it is, keep people and cars clear of it, and do not try to release or adjust it yourself. Federal safety guidance says a door that is unbalanced or binding should be serviced by a professional.

Permits

Permits for garage door work in Londonderry

What the town names. Londonderry's residential building permit page covers "additions, remodels, renovations, sheds, decks, porches, garages" and carports, with a $25 application fee on each residential building permit (Residential Building Permits). Overhead doors and openers never come up on that page or in the building FAQ, so the town has not said whether a straight door swap is permit work. Building & Zoning Enforcement, at 268B Mammoth Road and open weekdays 8:30 to 5, is the office to ask (Building & Zoning Enforcement).

When rot is the real job. The building FAQ lets owners re-shingle or re-side without a permit "provided there is no structural work involved," but replacing framing damaged by moisture brings a permit and a follow-up inspection (Building FAQ). Water that has sat against a garage door for decades often ruins the jambs and the bottom of the header, and by the FAQ's logic that framing repair is the part an inspector will want to see.

Paper and portal. Electrical permits, including a new ceiling outlet or circuit for an opener, are filed on the town's eSuite portal; the department notes that "Building permits are not available through our portal," so a widened or reframed opening goes in on a paper application (Building & Zoning Enforcement).

Posted fees. Under the fee schedule effective 11/4/25, residential additions, alterations and renovations run $8 per $1,000 of value with a $50 minimum, residential electrical additions and alterations cost $100 plus $3 per device, a reinspection is $50, and permits taken out after the work has started are doubled (fee schedule).

State rules, briefly. Under RSA 155-A:2 the town, not the state, issues permits and collects their fees. New Hampshire moved to the 2024 codes on July 1, 2026; through December 31, 2026 either edition is accepted, and from January 1, 2027 only the 2024 set applies (state code summary). Door companies hold no state license, which leaves the vetting to you; the Attorney General suggests references, proof of insurance and a signed contract before any money changes hands (NH AG). The rest is on our New Hampshire rules page.

Opener safety. Since 1993, federal rules have required residential openers to start reversing within 2 seconds of striking something and to carry entrapment protection such as a photo-eye or edge sensor (16 CFR 1211). The CPSC asks owners to inspect the door and opener every 30 days, to run a reversal test with a 2x4, and to leave a door that binds, sticks or is out of balance to be "serviced by a professional" (CPSC guide).

Historic review

Historic review and garage doors in Londonderry

The Town Common. Londonderry's Heritage/Historic District Commission works under state law and the Historic District section of the zoning ordinance (Heritage/Historic District Commission). Its business includes Certificates of Approval for work on the Town Common: the November 16, 2023 agenda, for example, took up a post-and-rail fence on a lot "Zoned AR-1 & Historic Overlay District" (Nov 16, 2023 agenda). The town's posted material does not say how the commission treats a new garage door or a changed opening, so if the property is on the Common, ask the commission before the door is chosen.

Outside the overlay. A 2007 Historic Properties Preservation Task Force judged 141 of more than 200 sites eligible for recognition and mapped 85 barns, and it recommended that any new protections be opt-in for owners (task force report). Elsewhere in town we found no design review of garage doors.

Weather and flood

Weather, wind and flood in Londonderry

Frost. The town posts no wind speed or snow load, but it is specific about depth: footings for a shed of 200 square feet or more go down 48 inches (Building FAQ), and deck footings at least 4 feet (Deck Construction Application). Nothing posted gives a separate depth for garage slabs or frost walls, so settle the foundation of a new detached garage with the building office.

Floodplain and brooks. The Hazard Mitigation Plan adopted May 19, 2025 states that within the floodplain district no new development that would increase flood levels in a 100-year flood is allowed without a variance, calls for an Elevation Certificate on substantial improvements in a known flood zone, and names Beaver, Todd, Little Cohas and Shields Brooks as streams where debris or ice jams threaten bridges (Hazard Mitigation Plan). A garage near one of those brooks deserves a look at the flood map before anything is added or enlarged.

Londonderry's homes

Connected farmhouses, barns and a suburb of single-family homes

The state's community profile counts 8,847 housing units in Londonderry, 7,346 of them single-family (NHES community profile, ACS 2009–2013, older data). The 2007 task force's definition of historic properties names Colonial, Federal and Victorian houses and the New England connected farmhouse, where the barn joins the house, alongside those 85 barns (task force report). Barn bays and carriage-style openings rarely match a stock door size, which is why older properties here often need a custom door or a reframed opening.

Room for a new garage. The zoning ordinance counts accessory structures and covered porches in building coverage, so a detached garage uses up part of the lot's allowance (Zoning Ordinance). In the AR-I district the FAQ gives setbacks of 40 feet in front and 15 feet at the sides and rear (Building FAQ).

FAQ

Londonderry garage door questions

Do I need a Londonderry permit to replace a garage door?

The town does not address garage doors in what it posts. Its residential permit page lists garages, remodels and renovations, and its FAQ says re-roofing or re-siding needs no permit unless structural work is involved. Ask Building & Zoning Enforcement before you order, especially if the opening will change.

What if the wood around my old door is rotted?

Londonderry's FAQ treats replacement of moisture-damaged framing as permit work with an inspection afterward. A soft jamb or header behind a garage door is framing, so expect the office to want a permit for that part of the job.

How much is the electrical permit for a new opener outlet?

On the fee schedule effective November 4, 2025, residential electrical additions and alterations are $100 plus $3 for each device, and work started before the permit is issued pays double. Electrical permits are filed through the town eSuite portal.

Can I build a detached garage in the floodplain?

Check with the town first. Londonderry's Hazard Mitigation Plan, adopted May 19, 2025, states that within the floodplain district no new development that would increase flood levels in a 100-year flood is allowed without a variance, and substantial improvements in a known flood zone need an Elevation Certificate.

What does it cost me to use New England Garage Door Pros?

Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
