What drives the price in Portsmouth

One of the densest stocks of 18th- and early-19th-century housing in the country downtown, with early-1900s neighborhoods beyond and post-war capes toward the edges. Pre-1900 work routinely involves timber framing, rubble foundations, and preservation-review constraints.

Cabinet tier: Cabinets are typically the single largest line item — often close to a third of the job. Moving from stock to semi-custom to full custom can double the cabinet line by itself.
Layout changes: Keeping sink, range, and refrigerator in place is the cheapest kitchen you can build. Moving the sink means new supply and waste runs; moving a gas range means a new gas line and often a new vent path.
Wall removal: Opening a kitchen to a living space usually means a load-bearing header, temporary shoring, and an engineer's letter for the permit. In older homes it also means finding out what is inside the wall.
Electrical service: Older homes frequently cannot support an induction range, a wall oven, and a microwave without a panel upgrade. That is a separate line item and a separate permit.
Countertop material: Laminate, butcher block, quartz, and natural stone span a wide range, and stone adds template and fabrication lead time between demo and finish.

Common Portsmouth neighborhoods where this work comes up: Downtown, South End, Little Harbor, Atlantic Heights, Elwyn Park.

Permits and rules in Portsmouth

Authority: City of Portsmouth Inspection Department

Building permit plus trade permits pulled by licensed trades. Much of the city falls inside the Historic District, where exterior changes require Historic District Commission approval before the building permit issues — plan that review into the schedule.

New Hampshire contract and licensing rules

New Hampshire does not license general contractors at the state level, so verification falls on the homeowner: confirm liability and workers' compensation coverage directly with the insurer, and confirm current state licenses for electricians and plumbers. With no statutory written-contract threshold, a written scope, payment schedule, and change-order clause matter more here, not less.

Timeline and season in Portsmouth

Coastal weather allows a slightly longer exterior season than inland, but salt air shortens exterior finish life. Historic-district review adds lead time in any season — winter is the time to design and permit, spring to build.

Typical duration: 8–14 weeks on site once materials are in hand.

1
Design and selections · 2–6 weeks
Layout, cabinet order, and every finish selection. Cabinet lead time drives the whole schedule — order before demolition.
2
Permitting · 1–4 weeks
Building permit plus separate electrical and plumbing permits. Historic-district review, where it applies, sits in front of this.
3
Demolition · 2–4 days
The scope-change window. Anything hidden — rot, old wiring, undersized framing — surfaces here.
4
Rough-in · 1–2 weeks
Framing changes, plumbing and electrical rough, inspections before anything is closed up.
5
Drywall and paint prep · 1 week
Board, tape, prime. Dust travels through the whole house during this phase.
6
Cabinets and counters · 1–3 weeks
Cabinets install, then counters are templated and fabricated — usually a 1–2 week gap before the stone arrives.
7
Finishes and punch list · 1–2 weeks
Backsplash, appliances, trim, lighting, final inspections, and the punch list.

What's included — and what usually isn't

A full kitchen remodel replaces cabinets, counters, appliances, flooring, and lighting, and usually touches plumbing and electrical. The spread between a modest refresh and a gut renovation with a moved wall is the widest of any room in the house.

Typically included

• Demolition and disposal of existing cabinets, counters, and flooring
• Cabinetry — stock, semi-custom, or custom, plus installation
• Countertops, backsplash, and sink cutouts
• Appliance rough-in and installation
• Plumbing fixtures and any supply or waste relocation
• Electrical: circuits for appliances, under-cabinet and ceiling lighting, code-required GFCI outlets
• Flooring, drywall repair, trim, and paint

Usually excluded

• Appliance purchase, when the contract lists it as an allowance rather than a supplied item
• Structural work to remove a wall (priced separately once an engineer sizes the beam)
• Panel upgrades required to add appliance circuits
• Asbestos or lead abatement discovered during demolition

What a complete Portsmouth estimate spells out

• Cabinet manufacturer, line, and door style — not just "new cabinets"
• Countertop material and a square-foot figure, with edge profile named
• Appliance allowance as a dollar figure, or the model numbers being supplied
• Who supplies and who installs each item
• Whether the price includes disposal, protection of adjacent rooms, and final cleaning
• A change-order clause with a stated markup

Full checklist: what should be in a contractor's estimate.

Kitchen remodel in Portsmouth — common questions

Should I order cabinets before demolition?

Yes. Cabinet lead times commonly run six to twelve weeks, and demolishing a working kitchen before the cabinets are in the shop turns a schedule gap into weeks without a kitchen.

Is a kitchen remodel worth it at resale?

Industry cost-versus-value data consistently shows minor and mid-range kitchen remodels recovering a larger share of their cost than high-end ones. A $30,000 refresh usually returns a better ratio than a $120,000 gut, even though the gut may be the right call for how you live.
