About 603 Websites
A New Hampshire web design partner, not a faceless agency
603 Websites designs, builds and manages websites for owner-led New Hampshire service businesses, then helps them get found, generate leads and keep improving online.
What we do
The website first, then everything that helps it bring in work
We design, build and manage websites for local service businesses. The site comes first because everything else depends on it: it has to be fast on a phone, say plainly what you do and where you work, and make it easy for someone to reach you before they try the next company on their list.
Once that foundation is right, we help it bring in more: getting found in search and on the map, keeping reviews coming, running Google Ads when they earn their keep, and setting up simple automation so a lead is answered while you are still on the job.

How we are set up
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.
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.
Why 603
The name is an area code, not decoration
603 is New Hampshire’s area code. We work in the same state and the same time zone as the businesses we build for, and the person who answers the phone already knows your site, instead of a queue or a rotating account manager.
We work with owner-led businesses across the state, whether you cover a few zip codes or drive an hour for the right job.
What to expect
How we work with owners
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.
How it works
Five steps, no mystery
Every step has a person attached to it and an answer in plain English.
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.
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.
