Granite Built.

Websites, apps and AI automations for New Hampshire businesses.

Built in Stratham, NH. Websites start with a free homepage preview, so you see it before you pay anything.

The DP Renewed Finish homepage on a laptop: a dark blue hero over a Mustang, with Get a quote and View packages buttons.
The Detailo app on a phone: a detailer's booking page with prices by vehicle size and a paid booking notice.
Both live right now: dprenewedfinish.com and detailo.app

Three things we build, all in house.

Most small businesses need one of these. Some need all three. Either way you talk to the people doing the work.

Websites

A site that loads fast, works on a phone, and makes calling you one tap. Built from your own photos, services and prices.

  • Tap to call and a way to ask for a quote
  • Your services, prices, hours and the towns you cover
  • Online booking if you want it
  • Your Google listing matched to the site

From $900, one timeFree homepage preview first. Ready in a week. See prices

Apps

Web apps your customers use from their phone. They install to the home screen like a normal app, no app store needed.

  • Booking with card payments
  • Automatic text and email reminders
  • Customer lists and an admin dashboard
  • Monthly subscription products you sell yourself

Fixed quote up frontDeposit to start, the rest at launch. See Detailo

AI automations

Work that runs by itself every day, so the boring part of your morning is already done when you sit down.

  • Daily lead reports delivered as an Excel file
  • Finding and scoring new prospects
  • First drafts of emails, call scripts and DMs
  • Built around how you already work

Fixed quote up frontDeposit to start, the rest when it runs. See two we built

We loaded 3,123 Seacoast business websites on a phone. 747 are broken.

Not a survey and not an estimate. Every dot is one real business around here, checked in September. Anything we couldn't confirm by hand, we left uncounted rather than guess.

One mark per website. Seacoast New Hampshire and 40 miles around it. September 2026

Another 3,180 businesses nearby have no website at all. If yours is one of them, or one of the 747, that's exactly who the free preview is for.

We build your homepage before you pay anything.

Not a mockup and not a slide deck. A real page you can open on your phone, built for your business, with your services and your town on it. If it beats what you have, we finish the site. If it doesn't, delete the link and we're done.

  1. We check your site and tell you what we found

    One quick call or email, a few specifics, no meeting. If there's nothing wrong with yours we'll say so. It happens, and we'd rather tell you than sell you.

  2. We rebuild your homepage, free

    Usually the same day. You get a link, you open it on your phone, you decide. Nothing is owed and there's no pressure.

  3. If you want the rest, we build it in a week

    Half up front, half when it's done. You tell us what's wrong with the draft and we fix it until it's right.

  4. We hand it over

    The site goes on your domain, in your name. No monthly fee and no contract unless you want us to keep looking after it.

What a website costs. One price, and you own it.

$900

One page, done properly

What you do, where you work, photos of it, and three ways to reach you. Ready in a week.

Most people take this one

$1,500

Five pages

A page per service, plus your work and your reviews. Includes text-back on missed calls for the first month, so a call you couldn't take doesn't become a customer you lost.

$2,500

Five pages, booking, Google sorted

Customers book themselves in, and your hours, photos and service area on Google finally match the site.

Seven days or your deposit back

If the draft isn't right within seven days, you get your whole deposit back and the draft comes down. The free homepage preview is yours to keep. We'd rather refund you than argue with you.

Monthly care, if you want it

It's optional. If you'd rather not deal with hosting and updates, we can handle them for a flat monthly fee that we quote before you sign anything.

Apps and automations

Every one is different, so each gets a fixed quote before work starts: a deposit up front, the rest at launch, and an optional monthly fee to keep it running.

Four things we've built for real clients.

Two you can open today, and two that stay private because they run on a client's own data.

Website

DP Renewed Finish

A paint correction, ceramic coating and trim restoration shop. Their site lays out every package, shows the work on video, and takes quote requests. The owner also has a private page where he can type a change in plain English and have it made.

App

Detailo

Built for a local detailer who sells it to people starting their own detailing business. Each one gets a booking page with card payments, automatic text reminders and a beginner playbook, all run from their phone.

1to 100How likely each business is to buy, from five things
  1. Pain
  2. Activity
  3. Ability to pay
  4. Lack of software
  5. Likelihood to respond

AI automation

LeadScout

A private lead finder for a detailing business. It scouts prospects state by state, scores every one, and writes the first email, call script or DM so the owner just has to send it.

Private tool, so no public link

AI automation

The morning lead report

For a recruiting firm. Every morning an Excel file lands in their inbox with the new sales job openings at the companies they go after, plus two or three decision-makers at each one, with emails marked verified or assumed.

Those are real column headers from the report. The client's data stays private.

Who you'd be dealing with.

It's the two of us. No project manager, no discovery phase, and no call that could have been an email.

Rhys Cartwright

18, from Stratham. Rhys builds the websites, apps and automations, and he built the system that checked those 3,123 sites. That system is why a site takes a week instead of a month, and why $1,500 is the real price instead of five thousand.

Colin

Rhys's partner in Granite Built. Colin works with clients alongside Rhys.

An agency charges you for its hours. We'd rather point what we've built at twenty businesses around here than three, and hand each one something they own outright.

Tell us your business name. That's all we need to start.

For a website, we'll check what you have and build you a free homepage preview. For an app or an automation, tell us what's eating your time. Usually back the same day.

Rather text? Send us a text with your business name.
