Most cost guides answer this with a range so wide it helps nobody. Here are the real brackets, what changes the number, and our own fixed prices in full.
A plumbing website costs a few hundred dollars a year if you build it yourself on a site builder, $500 to $3,000 from a freelancer working off a template, and commonly $3,000 to $15,000 from an agency building it custom. Our own plumbing website cost is fixed and published: $799 for a five-page site, $1,999 once you need a page per service and per town, and $3,999 and up for multi-branch work.
Those first three brackets come from pricing guides published by agencies selling the work, which is worth knowing when you read them. The last one is ours, and you can check it on our pricing page right now.
Not the feature list. These four answers move the price more than everything else combined.
How many services need their own page?
Drain cleaning, water heaters, boiler repair, and emergency callouts are four different searches. One page listing all four ranks for none of them properly. Each service that needs to rank on its own is a page that needs writing, and writing is the slow part.
How many towns do you actually serve?
A town page only works if it says something true about that town. Ten genuinely different town pages cost real money. Ten pages with the town name swapped cost less and are treated by Google as doorway pages, which is worse than not having them.
Does the site need to book jobs, or just take calls?
A click-to-call number costs nothing to add. Online scheduling that writes into your existing dispatch or CRM system is an integration, and integrations are where quotes separate. Be clear which one you need before you compare prices.
Who is writing the content?
If you supply the copy, the build is cheaper and usually better, because you know what customers actually ask. If the agency writes it, that is real hours. Quotes that seem unusually low often assume you are supplying everything.
Most cost guides never say what the company writing them charges. Here is ours, in full. Fixed, itemized, and agreed in writing before any work starts.
Starter
$799
A single-location plumber who needs to look credible and take calls.
Professional
$1,999
A growing firm that wants each service and each town to rank on its own.
Enterprise
$3,999+
Multi-branch operators and firms with dispatch or CRM systems to connect.
All three are fixed prices, not starting points. Terms are a 50% deposit on start and the balance on launch, and delivery runs 2 to 8 weeks depending on how many service and town pages the build needs.
Hosting and domain
Roughly $50 to $200 a year for a site this size. Pay it directly to the provider. Anyone marking it up is charging you for forwarding an invoice.
Keeping the software patched
A WordPress site left unpatched is the single most common way small business sites get defaced. Our care plan covers updates, backups, and monitoring from $99 a month, and you are free to do it yourself instead.
Search work
Optional, ongoing, and genuinely open-ended. It belongs in its own budget line, not folded into a build price where it becomes impossible to judge.
Content changes
Adding a service or a town later is a small job on a well-built site and an expensive one on a template that was never structured to grow.
A note on one-page sites
People search for the cost of a one-page plumbing website often enough that it is worth answering directly. It usually runs $300 to $1,500.
We do not sell them. One page can only rank for one thing, so drain cleaning, boiler repair, and every town you serve all end up competing against each other from the same URL. If the budget only stretches to one page, a five-page Starter build at $799 will do more for the same money over a year.
A share of the people searching this are not plumbers. They are designers and developers trying to price a job. Since the question keeps getting asked, here is a straight answer.
Price the structure, not the page count
A plumbing site earns its money through click-to-call placement, service-area schema, a page per service, and a page per town. Quote those as the deliverable and the number defends itself. Quote hours instead and you will lose the job to whoever guessed lower.
Use a published benchmark
Our own fixed prices sit at $799, $1,999, and $3,999 and up, and we publish them precisely so nobody has to guess. If your quote lands far below that, check what you have left out rather than assuming you are simply cheaper.
For most plumbing firms, somewhere between $799 and $3,999, plus about $100 a year for hosting and a domain. Anything below that range is a template you will outgrow, and anything far above it is usually paying for account management rather than for the site. The number that matters is the one written into a fixed quote before work starts, which is the only kind we send.
The questions plumbing firms ask us most often before a project starts, answered without a sales pitch. These cover what a build actually costs at each level, why two quotes for the same site can differ by thousands, what you should budget for after launch, how payment is staged, and whether a cheap template is ever the right call. If your question is not here, ask and we will answer it directly.

Building client websites since 2015
Last reviewed 1 August 2026. Outside figures used on this page are listed here with their source, so you can check them yourself instead of taking our word for it.
Published agency pricing guides put a custom plumbing website in the $3,000 to $15,000 range, and a fully bespoke coded build at $15,000 to $50,000. These are quoted ranges from agencies selling the work, not neutral survey data.
“This can range from $3,000 to $15,000+, depending on complexity and the agency’s expertise.”
Shopify Basic is $25 a month billed monthly, or $19 billed yearly. Grow is $65 and Advanced is $399. These platform fees sit outside any build cost.
Google treats a page as fast on three measures. Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. All three are read at the 75th percentile of real page loads.
“LCP should occur within 2.5 seconds of when the page first starts loading.”
