New Hampshire website design
Websites built to grow New Hampshire businesses
For owner-led service businesses across the state — HVAC, roofing, landscaping, plumbing, electrical, auto shops, and the appointment-based experts people book by phone.
- New Hampshire based
- Owner-led local businesses
- One point of contact
Local accountability, plain English, and ongoing support
Based in New Hampshire
When your site needs attention, the person responsible for it is in the same state and answers for the work.
Plain English, always
We explain what your site needs the way you would explain a quote to a homeowner standing in their driveway.
One point of contact
The same person takes your first call and every change request after launch. No rotating support desk.
Support that continues after launch
Launch day is when a service website starts earning, so the updates, fixes and improvements keep going.
About 603 Websites
A New Hampshire web design company for service businesses
603 Websites builds and manages websites for local service businesses. The website is the foundation: fast on a phone, clear about what you do and where you work, and built so someone who finds you at nine at night can reach you before they call the next company on their list.
A good site is the start, not the finish. From there comes the growth layer — getting you found in search and on the map, keeping reviews coming in, running ads when they earn their keep, and using simple automation so a lead gets answered while your crew is still on a roof or under a truck.
Behind all of it is one accountable local partner. Specialist production help happens quietly in the background, but you are never handed off. The same contact plans the work, reports on it, and picks up when you call.
What we do
Web design first, then the growth layer
Two services build the foundation. The rest grow what it brings in. Most owners start with the website, get it right, and add the growth work as the season allows.
The foundation
Website Care
Hosting, maintenance, backups and security handled while you are out on jobs.
The growth layer
SEO & Content
Show up in search for the work you actually do, with reporting you can read.
Local SEO
A Google Business Profile that pulls calls from the areas you already drive to.
Paid Growth
Google Ads aimed at the jobs you want. Media spend is billed separately.
Reputation & Leads
Review management, faster follow-up, and a clear read on who is calling.
AI & Automation
Website chat, forms and simple automations that answer people after hours.
When you need more
Branding, e-commerce, calculators and portals when a standard build is not enough.
Every service has its own page with what is included and how it runs. Or call and we will tell you plainly which ones you do not need yet.
See all servicesWho we build for
Local service businesses we build for
If a call, a quote request or a booked appointment is what turns into revenue, your website has one job. Most of the people looking for you are holding a phone while they decide.
Trades and home service contractors
Your year swings with the weather. Your site has to turn a search into a call while the problem is still fresh.
HVAC, roofing, landscaping, painting, plumbing, electrical, fencing, excavation and cleaning
Automotive and specialty shops
The person looking for you is usually stranded, late, or both. Say plainly what you handle and keep the call button in thumb reach.
Repair, detailing, towing, transport and specialty shops
Professional and appointment-based businesses
People often hear about you before they ever open your website. It has to back that up and make booking the next step feel simple.
Legal, financial, wellness and consulting practices
Established owners who outgrew what they have
You built the first site yourself, inherited one nobody has touched in years, or hired a freelancer who stopped replying. The company kept growing and the website stayed put.
DIY site builders, outdated websites and unreliable freelancers
Where we work
Local to New Hampshire, working statewide
The 603 in our name is an area code, not decoration. Same state, same time zone, and the same person answering the phone — someone who already knows your site instead of a queue or a rotating account manager.
One name, one number
You get a direct line to the person responsible for your website, and they know your business without being re-briefed.
Specialists, managed by us
Some work calls for a specialist. We bring the right one in and manage them, so the responsibility stays local.
The whole state
We work with owner-led businesses across New Hampshire, whether you cover a few zip codes or drive an hour for the right job.
How it works
How a website project works with us
Five steps, no mystery. Every one of them has a person attached to it and an answer in plain English. You should not have to chase your web guy between jobs.
Book a call
We spend a call on your trade, the work you want more of, and how people find you right now.
Plan and scope
You get the pages, the scope and the timeline in plain English before the build starts.
Build the site
We build a fast, mobile-first site around the way people actually hire a service business.
Launch and check
We test it on a phone the way your customers hold one and confirm leads land where a person answers.
Growth and care
Hosting, updates and security keep running, and we add visibility, reviews or ads when you want the phone ringing more.
Projects are quoted after a call, not from a price list. When we run Google Ads, the media spend is billed separately and stays yours. Contracts, hosting billing, who owns the site, and timelines are all covered in the FAQ.
By industry
What we build, by industry
Every build is shaped by how people actually hire that kind of business. Completed New Hampshire projects get their own write-up on the portfolio page as they go live.
The shape of a build
Roofing and exteriors
A phone-first site so a homeowner with water coming through a ceiling can tap once to call and see the area you cover.
Electrical and mechanical trades
Service pages that say plainly what you handle, with quote requests that reach the phone someone actually answers.
Automotive and specialty shops
Built around the only two questions a driver has: do you work on this, and how soon can you get to me.
Appointment-based practices
A quieter site that explains who you help and what a first visit involves, so people book instead of closing the tab.
What you can hold us to
No quotes we wrote ourselves
Plenty of agency sites carry a wall of glowing quotes from people you cannot call. We would rather hand you the terms of the relationship and let you judge those instead.
You talk to the person accountable
Specialist production help happens behind the scenes, but the relationship stays with one local contact. You are never handed off to someone you have not met.
Plain English, including the bad news
No reports full of terms you have to look up. If something is not worth your money before your busy season, we will say so on the call.
We are still here after launch
Hosting, maintenance, updates, backups, security and ongoing improvements are part of the relationship, not a separate project you have to chase.
Ad budget stays yours
When we run Google Ads, the media spend is billed separately and stays your money. We manage the campaigns, not your card.
Next step
Book a call about your website
Talk to the person who would build it.
A short call, no pitch deck. You tell us what you have now, what is getting in the way, and the work you want more of. If a new site is not the thing your business needs this year, we will say so on the call.
If we are not the right fit, we will tell you that too.
Not ready to talk yet? The common questions cover contracts, how hosting and care are billed, who owns the site and the codebase, and how long a build takes.
