Siding in Concord

What's different about siding in Concord

Concord's siding challenge is the building science of a cold New England winter. The city runs months of sub-freezing temperatures, deep snow, ice damming at the eaves, and many freeze-thaw cycles each season. Moisture that gets behind the cladding can freeze, expand, and progressively damage sheathing and framing. A Concord re-side should be planned around the full wall assembly — weather-resistive barrier, air sealing, flashing, and ideally a rainscreen drainage gap — not just the panel that shows. Get the water management right and the cladding lasts decades; get it wrong and the wall rots from the inside out.

Concord's housing stock is old and varied. The neighborhoods around downtown, the South End, and the West End hold dense stretches of 19th- and early-20th-century homes — Greek Revival, Victorian, foursquare, and Cape forms — many still in original wood clapboard or wrapped in mid-century aluminum or early vinyl. Removing old cladding on these homes regularly exposes original wood, soft sheathing, or hidden rot near windows and sills. A Concord re-side is rarely a clean swap; the condition behind the old surface is what sets the real price.

Material choices here run the full New England range. Wood clapboard remains common on historic homes; fiber cement is popular as a durable, low-maintenance look-alike; and vinyl and insulated vinyl are widely used on more modest housing. Energy performance carries real weight in a climate with this many heating-degree-days, which makes insulated vinyl and exterior insulation worth serious consideration. Our siding-comparison article walks through how those materials trade off on cost and durability.

Concord permits: where to file

A residential re-side inside Concord requires a building permit from the city, and the permit ties your new wall assembly to the code Concord enforces.

Inside the City of Concord, siding replacement is permitted through the Code Administration office, which houses the Building Division. A like-for-like re-side does not require stamped plans — the contractor files a building permit application describing the wall area, scope, and material. New Hampshire enforces a statewide building code based on the International codes, and Concord administers and inspects it locally. Inspections confirm the weather barrier and fastening are correct, so keep the permit accessible on-site through the job.

If your address is outside the city line — in unincorporated territory or a neighboring town such as Bow, Pembroke, Loudon, or Penacook's surrounding area — the Concord permit does not apply, and the relevant town's building office handles the work with its own fees and inspectors. New Hampshire towns vary considerably in how they administer permits. Ask your contractor to name the exact permitting jurisdiction on the written contract before any siding is removed.

• New Hampshire state building code
  New Hampshire adopts a statewide building code based on the International Residential Code, administered locally by Concord. A re-side must meet the weather-barrier and fastening provisions of the enforced edition — make sure your contractor's scope references current code, not an outdated one.
• Historic district review
  Concord has locally designated historic areas and a Heritage Commission. Exterior work on a contributing structure in a designated district can require review before a permit issues. An in-kind replacement that preserves material, profile, and trim is the simplest path through.
• Lead-paint precautions on older homes
  Much of Concord's housing predates 1978, so lead paint under old clapboard and trim is common. Disturbing it triggers federal RRP lead-safe work practices. A reputable contractor contains dust and debris rather than dry-scraping old paint into the yard.

Typical siding replacement cost in Concord

Concord's cost of living runs near or slightly above the national average, and siding labor reflects both that and the demands of working on older homes in a short building season. The biggest budget variables are home age and hidden condition — a century-old home with trim work and surprise rot costs well above a straightforward suburban job. Treat the figures below as directional ranges.

Neighborhoods where siding looks different

Concord's neighborhoods differ in age and architecture. A few specifics worth knowing before bidding:

• Downtown and the historic core
  The streets around Main Street and the State House hold Concord's oldest and most architecturally significant homes. Re-sides here are detailed and may involve Heritage Commission review; matching original clapboard and trim is the expectation.
• South End
  An established residential neighborhood of 19th- and early-20th-century homes on tree-lined streets. Re-sides lean toward in-kind wood or fiber-cement look-alikes; budgets should anticipate finding original wood and possible rot behind aluminum.
• West End and Penacook
  Mixed older housing including former mill-village stock in Penacook to the north. These are common re-side candidates, often budget-driven, with vinyl and insulated vinyl widely used.
• Newer subdivisions on the city edges
  Mid-century and later ranches, capes, and colonials on flatter ground away from the old core. These are more standard re-side projects, though cold-climate flashing and insulation detail still matter.

Concord weather events siding contractors still reference

Concord's siding perils are cold-climate New England weather, not coastal storms. These are the events local crews still cite.

• 2008
  December 2008 Ice Storm

  A severe ice storm coated central New Hampshire in heavy ice, downing trees and power lines and leaving widespread, days-long outages. Ice loading and falling limbs are a recurring Concord peril that can crack and tear cladding and trim.
• 2017
  October 2017 windstorm

  A powerful October wind event downed trees and caused extensive power outages across New Hampshire. High straight-line winds are the metro's main wind peril for siding, driving debris into walls and stripping panels.
• 2006
  Mother's Day flood

  Heavy May 2006 rainfall flooded parts of New Hampshire along the Merrimack and other rivers. Rising water is a flood-policy matter, not a homeowners claim — a distinction river-adjacent Concord homeowners should keep clear.

Concord siding FAQ

• Do I need a permit to replace siding in Concord?
  Yes. A residential re-side inside Concord city limits requires a building permit from the city's Code Administration office. A like-for-like replacement does not need stamped plans, but the permit must be pulled and kept on-site for inspection. Skipping it leaves no inspection record, which can complicate a sale or future claim.
• What siding works best in Concord's cold climate?
  All the mainstream materials can perform here, but the wall assembly matters more than the panel. Proper weather-resistive barrier, air sealing, flashing, and ideally a rainscreen drainage gap protect against ice damming and freeze-thaw damage. Insulated vinyl and exterior insulation also improve energy performance, which is a real concern in this climate.
• What's usually hiding under my old aluminum or vinyl siding?
  On a typical older Concord home, mid-century aluminum or early vinyl was installed over original wood clapboard. Beneath it you may find sound sheathing, soft or rotted sheathing near windows and sills, or worn original wood. A good contractor inspects representative areas before quoting and writes hidden-repair allowances into the contract.
• My home is in a historic district — can I re-side it?
  Yes, but exterior work on a contributing structure in a designated district can require Heritage Commission review before a permit issues. An in-kind replacement that preserves the original material, profile, and trim is the simplest path. Changing material or visible character is more likely to need review.
• Should I add insulation when I re-side?
  A re-side is the ideal moment to improve a Concord home's energy performance. Adding continuous exterior insulation and air sealing during the project costs far less than doing it separately and pays back through lower heating bills over New Hampshire's long winters. Discuss insulation and air-barrier detail with your contractor up front.
• Will my homeowners policy cover storm-damaged siding?
  Wind damage from a windstorm or severe thunderstorm, and damage from ice and falling limbs, are generally homeowners claims. Damage from rising river water is not — that falls to a separate flood policy. Know which peril caused the damage before you file.
• How long does a Concord re-side take?
  A straightforward vinyl re-side often runs four to seven working days; a detailed older home in wood or fiber cement can take two to four weeks once trim work is involved. New Hampshire's short building season concentrates demand from spring through fall, so book well ahead.
