A plumbing website has one job and it is not to win a design award. It has to be found by someone with water on the floor, load fast on a phone with one bar of signal, tell them you cover their town, and put a tappable phone number where their thumb already is. Most plumbing sites fail at least two of those, usually because they were designed for a laptop screen by someone who never watched a customer use one. This guide covers what to demand from a designer, what the work should cost, and how to check the result yourself without hiring a second expert to grade the first.
What the site actually has to do
Start from the customer. Most emergency plumbing searches happen on a phone, often at an awkward hour, and the person searching wants three facts fast: do you cover my area, can you come now, and what is the number. So the design brief is short and strict. The phone number belongs at the top of every page and it must be a tappable link, not an image. The service areas belong in text a search engine can read, not on a map widget that loads after everything else. Emergency availability, if you offer it, belongs above the fold. Beyond the emergency case, you need a page per service you want to be found for: drain cleaning, water heater replacement, repiping, sewer line, boiler work. One crowded services page cannot rank for all of them, because search engines rank pages rather than businesses, and a page that covers six trades in six paragraphs is a weaker answer than a page that covers one properly.
Speed and structure are design decisions, not fixes
Whether a site is fast is decided at design time, by image weight, font loading, script bloat and the habits of whoever assembles the theme. Google publishes Core Web Vitals as its measures of loading, interactivity and visual stability, and a heavy page cannot be made light afterwards without rework. Before you hire anyone, take the three most recent sites in their portfolio and run them through a free page speed test on a mobile setting. If their existing work is slow, yours will be too. The second structural check is just as easy: open a delivered page and view its source. Your headline, your service copy, your town names and your phone number should be present in the raw HTML. Google can render JavaScript but its own documentation treats rendering as a complication to manage, and there is no reason for a plumbing site to take that risk. Put both a speed target and a source-visible content requirement into the contract as acceptance criteria.
Design and search are the same purchase
The single most expensive mistake in this trade is buying a site and buying search visibility as two separate purchases, months apart, from two firms who each blame the other. A site laid out without a page plan has to be partly rebuilt for the pages to exist at all, and you pay twice. Ask the designer, before the deposit, which pages the site will have and which search phrase each one is meant to answer. If the answer is a five page brochure, that is a brochure, not a lead source. Many owners end up buying design and search together as one engagement for exactly this reason, and it is usually cheaper than sequencing them. It also removes the argument about who is responsible when the finished site does not appear for the town next door.
What it costs and what protects you
Pricing in this trade covers an enormous range, from a few hundred dollars for a template with your logo dropped in to five figures for a custom build with booking integration. What you are really paying for is pages, copy, photography and the hours to make it fast, so ask for the quote broken down that way and compare like with like. Then protect yourself with four contract terms. You own the domain, registered in your name, not the designer's. You own the hosting account or can move it. You own the content and the images, including the licence to any stock used. And you get the site files if the relationship ends. Agencies holding a domain hostage is the single most common horror story in local trades, and it is entirely preventable with one clause and five minutes at a registrar.
Questions people ask about web design for plumbers
How many pages does a plumbing site need?
One page for every service you want calls for, plus one for each significant town or service area, plus the usual home, about, reviews and contact pages. That commonly lands between ten and thirty pages for a single-van operation. Fewer pages means fewer things you can be found for, and that is the whole point of the site.
Do I need a custom design or is a template fine?
A well built template is fine for most plumbing businesses and often faster and cheaper to maintain. What matters is speed, mobile behaviour, page structure and the copy on the page. Spend the money you save on more service and town pages, which will do more for the phone than a bespoke layout will.
Should the designer also write the content?
Someone has to, and it should not be filler. Good copy in this trade comes from your actual jobs: what goes wrong, what it costs to fix, what a customer should do before you arrive. If the designer writes it, review it for accuracy. Generic plumbing prose ranks poorly and converts worse.
How do I check the finished site myself?
On a phone: tap the number and confirm it dials, load the site on mobile data rather than wifi and time it, and read the whole home page without pinching. On a laptop: view source and confirm your services and towns are in the HTML. Then search your business name and confirm the site appears with a sensible title and description.
