Best General Contractors in New Hampshire 2026
Finding a reliable general contractor in New Hampshire takes more legwork than in states with strict licensing requirements. New Hampshire does not have a state-level general contractor license — anyone with a business registration can call themselves a contractor, which means the range in quality is enormous. The best GCs in the state carry proper insurance, employ skilled tradespeople, pull permits without being asked, and manage projects on timeline and budget. The worst will take your deposit and disappear, or deliver work that fails inspection. We evaluated contractors across the state based on licensing and insurance verification, client reviews, project quality, warranty coverage, and financial stability. These are the top general contractors in New Hampshire for 2026 — vetted for homeowners planning renovations, additions, or new construction.

1. Northpoint Construction — Manchester/Southern NH
Northpoint Construction has been building and renovating homes in southern New Hampshire for 16 years, with a portfolio that spans kitchen and bath remodels, whole-house renovations, and custom additions. Use our renovation ROI calculator for detailed numbers. Owner Brian Kelley runs a crew of 14 full-time employees (not subcontractors for core work), which gives him better quality control than outfits that sub out everything. Northpoint carries $2M in general liability and full workers’ comp. Their specialty is renovating pre-1960 homes in Manchester and Nashua — dealing with the old wiring, plaster walls, and structural quirks that come with New England housing stock. Average project size is $45,000-$180,000, and they maintain a 2-year workmanship warranty beyond manufacturer warranties on materials.
Service Area: Manchester, Nashua, Concord, Bedford, surrounding towns
Specialties: Whole-house renovation, historic homes, additions
Insurance: $2M general liability, full workers’ comp
Warranty: 2-year workmanship

2. Seacoast Builders Group — Portsmouth/Dover/Exeter
Seacoast Builders Group dominates the high-end renovation and custom building market along the NH coast. Founded in 2008, the firm has completed over 200 projects ranging from $80K kitchen remodels in Portsmouth’s historic district to $1.2M waterfront homes in Rye. Their team includes a full-time project manager for every active job, which keeps communication consistent and prevents the “where’s my contractor?” problem that plagues so many renovation projects. They’re particularly skilled at navigating the historic district requirements in Portsmouth and the Shoreland Protection Act regulations that affect coastal properties. Lead times are longer than average — typically 3-4 months from contract to start — but the project execution is consistently on schedule.

Specialties: Custom homes, high-end renovation, historic preservation

3. Granite State Remodeling — Statewide
Granite State Remodeling is the largest dedicated remodeling company in New Hampshire, with offices in Manchester and Concord and crews working from the seacoast to the Lakes Region. Their strength is mid-range renovations — $25K-$85K kitchen and bath projects where they’ve streamlined the process with preferred material suppliers, in-house design consultation, and a fixed-price contract model that eliminates the dreaded “change order creep.” They complete roughly 350 projects annually, which means their supply chain relationships keep material costs competitive. The trade-off for their scale is less customization — they work from a defined palette of materials and finishes rather than sourcing custom everything. For homeowners who want a quality renovation without the custom-build price tag, they’re hard to beat.

Owner Mark Provencher grew up in Laconia and knows the local building departments, soil conditions, and subcontractor networks that make lakefront projects succeed or fail. They handle everything from dock and retaining wall construction to full lakefront home builds, with particular expertise in winterization and energy efficiency upgrades for homes that take a beating from Winnipesaukee weather.

What New Hampshire Doesn’t Require (But You Should)
New Hampshire’s lack of a general contractor license means the state doesn’t verify competence, financial stability, or insurance for GCs. This puts the vetting burden on you. Here’s what to verify before signing any contract:
- General liability insurance: Minimum $1M, preferably $2M. Ask for a certificate of insurance naming you as additional insured. Call the insurance company to verify it’s active — certificates can be forged or expired.
- Workers’ compensation: Required for any contractor with employees. Without it, you could be liable if a worker is injured on your property. No exceptions.
- Trade licenses: While GCs don’t need a license, electricians and plumbers must be licensed by the state. Verify that the subcontractors your GC uses hold current NH trade licenses.
- Business registration: Verify the contractor is registered with the NH Secretary of State’s office. This doesn’t guarantee quality, but an unregistered contractor is operating illegally.
- BBB and AG complaints: Check the Better Business Bureau and NH Attorney General’s Consumer Protection Bureau for complaints. A pattern of unresolved complaints is a deal-breaker.
- References: Get at least 5 references from projects completed in the past 12 months. Actually call them. Ask about timeline adherence, communication, cleanliness, and how the contractor handled problems that arose.

Frequently Asked Questions
Does New Hampshire require contractors to be licensed?
No — New Hampshire does not have a state-level general contractor license. Anyone can legally operate as a GC with just a business registration. Electricians and plumbers must hold state licenses, and gas fitters need certification. This lack of GC licensing means you must do your own vetting — check insurance, references, and complaint history before hiring anyone. The absence of licensing is one reason why asking for proof of insurance and workers’ comp is non-negotiable in New Hampshire.
How much should I pay upfront to a contractor?
Never pay more than 30% upfront, and 10-20% is standard for reputable contractors. Structure payments as milestones — a deposit at signing, payments at defined completion stages (demo complete, rough-in complete, finish work complete), and a final payment of 10-15% held until a final walkthrough and punch list items are resolved. Any contractor demanding 50%+ upfront is a red flag. For larger projects, use an escrow arrangement through your bank or attorney. Budget planning starts with our mortgage calculator if you’re financing the work.
How far in advance should I book a contractor?
For major projects (kitchen/bath remodel, addition), book 2-4 months ahead during the building season (May-October). The best contractors are scheduled out even further — 4-6 months is not uncommon for top-tier firms. Winter interior projects can often be scheduled with shorter lead times (4-8 weeks) because demand dips. Start getting bids in January for a spring/summer project. Waiting until April means you’re competing with everyone else who just had the same idea.
What should be in a contractor’s written contract?
A proper contract includes: detailed scope of work (not just “remodel kitchen” but specific materials, brands, and finishes), total price with line-item breakdown, payment schedule tied to milestones, start date and estimated completion date, change order process and pricing, warranty terms, permit responsibility (contractor should pull all permits), insurance certificates, and cancellation/dispute resolution terms. If a contractor won’t put it in writing, don’t hire them. Period.
How do I handle disputes with a contractor in New Hampshire?
Start with direct communication — most disputes stem from miscommunication about scope or expectations. If that fails, send a written demand letter outlining the issue and requested resolution. The NH Attorney General’s Consumer Protection Bureau accepts contractor complaints and can mediate. For disputes over $10,000 or less, small claims court is an option. For larger amounts, you may need an attorney. Having a detailed written contract with dispute resolution terms makes this process much smoother. Always document issues with photos and written correspondence.
Should I hire a contractor or do the renovation myself?
DIY works for cosmetic projects — painting, flooring installation, simple landscaping. Anything involving structural changes, electrical, plumbing, or load-bearing walls should be done by a professional. In New Hampshire, electrical and plumbing work requires a licensed tradesperson regardless. The cost savings from DIY on a kitchen remodel are typically 30-40%, but the risk of errors, code violations, and safety issues is real. A good middle ground: hire a GC for the skilled work and handle demo, painting, and cleanup yourself to save $2,000-$5,000. Our home services directory can connect you with vetted professionals.
What’s the average cost of hiring a general contractor in NH?
GCs in New Hampshire typically charge either an hourly rate ($65-$95/hour for management time) or a markup on total project costs (15-25% above the combined cost of materials, subcontractors, and labor). On a $50,000 kitchen remodel, the GC’s fee would be roughly $7,500-$12,500. This covers project management, scheduling, permit coordination, quality control, and warranty backing. Some GCs offer fixed-price contracts that include their fee in the total — this is usually the cleanest arrangement for homeowners because the price is the price, absent change orders.
