Onelios is a free plumber website builder: its AI drafts your site from your business name, trade and city for you to review and publish, and the site collects quote and appointment requests in one inbox and publishes reviews your customers write.

What Onelios does for you
- Your website: Type your business name, pick Plumbing and type your city or service area. The AI drafts a headline, the line under it and your services, and you preview it in desktop and mobile views before making an account. Generation time varies.
- Service pages: Ask for a page for a job — water heater replacement, drain cleaning, repiping — and it is written, published and linked from your site: an introduction, what’s included, common questions and a Request a quote button.
- One inbox: Quote and appointment requests are saved in your dashboard, and an email alert to you is attempted for each one. When the customer left an email address, replying to that alert answers them directly.
- Reviews: Pick a customer after a job and Onelios emails them a private link. They write the review themselves and it publishes on your site. Email only: no text messages, and no replying to reviews from Onelios.
- Monday email: What came through your website that week — quote requests, appointment requests, new reviews — a count of that week’s requests still unanswered after 48 hours, if any, and one thing to post by hand on your Google Business Profile. Phone calls and texts are not counted, and it says so.
What should a plumbing website include?
A plumbing website needs a phone number to press, your license number where your state requires it, the jobs you take, a page for each big one, where you go, honest hours, photos of your work, reviews customers wrote, and a quote form. The Federal Trade Commission tells homeowners to confirm a contractor’s license and ask for proof of insurance.
Here is the checklist, with how each item is done in Onelios.
1. A phone number people can press, and two buttons on the first screen. Someone with water coming through a ceiling wants to call, not read; someone planning a repipe wants to send details. Type your number into the phone field and your homepage shows a Call button at the top and a Request a quote button on the first screen, on a phone as well as a computer, and the quote form repeats the number. Leave it blank and that button points to the quote form or appointment requests instead.
2. Your license number, where the law expects it. California, Texas, Florida and Washington all require a license or registration number in advertising; the next section has the exact rules. There is no license field, so you type it in yourself.
3. The jobs you take, in the words customers use. A new plumbing site starts with emergency repairs, drain cleaning, water heaters, fixture installation, repiping and leak detection. Remove what you do not do and add what you do, so nobody calls about work you turn down.
4. A page for each big job. Water heater replacement, repiping, sewer lines and drain cleaning are worth a page of their own, because the Federal Trade Commission tells homeowners to get multiple estimates, so your page is read beside other plumbers’ pages. In Onelios, type a page title of up to 80 characters, such as Water heater replacement, and the page is written, published and linked from your site, up to ten new pages an hour. These are service pages: Onelios does not make a page for each city you serve.
5. Where you go. Onelios asks for a city or service area, not a street address, and your site shows the area you typed. Name the towns you actually drive to in the line under your headline, which holds 240 characters. Google’s Business Profile guidelines use a plumber working from a home address as their example of a business that should hide its address, and say a service area generally should not extend farther than about two hours’ driving time from where the business is based.
6. Hours that are true. “24/7” on a plumbing site is a promise someone has to keep at 3 a.m. The AI is instructed not to write response times such as 24/7 or same-day unless you give them, so if you do answer at night, say it in your own words.
7. Photos of your own work: a water heater with neat piping, a finished bathroom, a crawlspace before and after a leak repair. Upload JPEG, PNG or WebP photos from your phone or computer; they are resized before upload, and a gallery appears on your site. Until you add one there is no gallery; Onelios does not fill it with stock pictures.
8. Reviews your customers wrote, sent for by email after the job. The customer writes it through a private link and it appears on your site. Once you have reviews, the rating markup search engines read is added to your site, and not before: Onelios never puts a star rating on a site with no reviews.
9. A quote form. Onelios’s form asks for a name, a phone number or email, the service and a message of up to 2,000 characters. It has no photo upload. If a photo would help you price the job, reply to the alert email — when the customer left an email address, your reply goes straight to them.
10. What a visit costs, if you charge for one. If you have a trip or diagnostic fee and want callers to know it before you arrive, write it in yourself. The AI is instructed not to add prices you did not give it, and nothing on the site prices a job for you.
11. Insurance, stated carefully. The Federal Trade Commission tells homeowners to ask for proof of insurance, so if you carry it, say you will show proof. In California, do not write that you are bonded: the Contractors State License Board’s advertising guide says the law prevents contractors from saying so in advertising.
12. Your own domain. The free onelios address is kept out of Google on purpose. Connect a domain you already own — connecting is free, we do not sell domains, and it stays with your registrar — and the same site can appear in Google, when and where Google decides.
13. Check it on a phone. The preview at /start shows desktop and mobile views before you make an account; switch to Mobile and check that the Call button sits at the top and your number is right, as in the phone picture above. Do the same after any rewrite you ask for.

Do plumbers have to put a license number on their website?
In several states, yes. California requires a contractor’s license number in all advertising, and its contractors board counts websites. Texas requires the Responsible Master Plumber’s license number in advertisements for plumbing work, whatever the medium, with narrow exceptions such as radio. Florida and Washington have similar rules. Check your own state’s board, then type the number onto your site yourself.
California. Business and Professions Code section 7030.5 says every licensed contractor must include the license number in all construction contracts, subcontracts and calls for bid, and in all forms of advertising. The Contractors State License Board’s advertising guide lists “any website or post that solicits business on the Internet” as advertising and puts the civil penalty for a first offense at $100 to $1,000. Plumbing contractors (the C-36 license) have a stricter vehicle rule than most trades: business name, address and license number on each side of every commercially registered vehicle, in letters at least 1½ inches high.
Texas. The State Board of Plumbing Examiners’ rule 22 TAC §367.10 makes the Responsible Master Plumber (RMP) of record and the company owner responsible for stating the RMP’s license number in all advertisements designed to solicit plumbing business, “regardless of the type of media used.” The board’s penalty guideline for leaving it out is $1,000. Service vehicles carry the number on both sides, preceded by “M,” “MPL” or “RMP,” in letters at least two inches high. The first page of every written or electronic estimate, invoice or contract needs the RMP’s name and license number, the phrase “regulated by the Texas State Board of Plumbing Examiners,” and the board’s mailing address, phone number and website.
Florida and Washington. Florida Statutes section 489.119, which covers plumbing contractors among other construction contractors, says the registration or certification number must appear in each offer of services, bid, contract or advertisement, “regardless of medium”; the board issues a notice for a first offense and may fine a contractor who has not corrected it within 30 days. Washington’s RCW 18.27.100 says all advertising that shows a contractor’s name or address must show the current registration number.
Other states set their own rules and we have not checked them; your state’s plumbing or contractor licensing board publishes its own. In Onelios, type the number into the line under your headline in the site editor, which holds up to 240 characters. The AI is instructed not to add licenses or other credentials you did not give it, so it will not write one for you. It can still make mistakes, so read that line again after any rewrite you ask for.
How should a plumbing website handle emergencies and planned jobs?
Differently. An emergency visitor needs a Call button on the first screen of a phone and nothing in the way. A customer planning a water heater replacement or a repipe has time to compare photos, reviews and license details. Online appointment requests suit planned work; a burst pipe needs a phone call.
Appointment requests in Onelios start once you save your working days, hours and time zone; until then the site offers the quote form. Customers pick a start time up to two weeks ahead. The request holds that start time, so a second customer cannot ask for the same one, and it lands in your inbox for you to confirm. Overlapping jobs, travel time and appointments in an outside calendar are not checked, so look at your week before you confirm.
When a request arrives, it is saved in your inbox and an email alert to you is attempted; check the inbox even if no email comes. If the customer left an email address, replying to the alert answers them, and a verified account can send a confirmation email with the Confirm the time by email button. A customer who left only a phone number is yours to call. There are no text messages and no automatic reminders.
Service pages you add, such as burst pipes or drain cleaning, have a Request a quote button and a link back to your homepage. For a planned job, the page that does the work is the one with your own photos, your license number and reviews from customers you actually served.
Which service pages are worth adding for a plumbing business?
Pages for the jobs you most want: water heater replacement, drain cleaning, leak detection, repiping. Ask for one in plain words and Onelios writes it, publishes it and links it from your site, with an introduction, what’s included, common questions and a Request a quote button. If a page gets something wrong, remove it and ask again.
Water heaters. If you install heat pump water heaters, leave the federal tax credit off the page. The IRS says its Energy Efficient Home Improvement Credit, 30% of the cost up to $2,000 a year for a heat pump water heater, covers improvements made through December 31, 2025. Mention a state or utility rebate only after reading its own page, and say when you read it.
Repiping and sewer lines. The Federal Trade Commission tells homeowners to get multiple estimates, so a repiping or sewer-line page is read beside other plumbers’ pages. Read it as that homeowner would: if it names a price, a material or a promise that is not true of your business, remove the page and ask for it again.
Leak detection. The EPA’s WaterSense program says the average household’s leaks can waste more than 9,300 gallons of water a year, and that nine percent of homes have leaks wasting 50 gallons or more a day; worn toilet flappers, dripping faucets and other leaking valves are the common ones it names. It runs Fix a Leak Week every March (it ran March 16 to 22 in 2026), so a leak-check page is worth having ready before next March.
City pages. Onelios does not write a page for each town you serve; its pages are service pages, and your service area is the line you typed. If you want a list of towns on the site, put it in the line under your headline.
The AI is instructed not to invent prices or credentials on these pages either, and it can still make mistakes, so open each new page on your phone and read it the way a customer would.

Common questions
Is there a free website builder for plumbers?
Onelios is free right now: building the site, publishing it, connecting a domain you already own and every tool, with no card. A small “Site by Onelios” line stays at the bottom. We do not sell domains; if you want your own address, buy it from any registrar and connect it free.
What is the best website builder for plumbers?
It depends on what else you need. For invoicing and payments with the site, Jobber includes a generated website in every plan (Core, $49 a month, read September 23, 2026). For a site built for you, Housecall Pro’s team does it from $99 a month plus a $99 setup fee. For a free site with a quote form, appointment requests and reviews, and no card, Onelios; it has no invoicing or staff logins.
Do plumbers have to show a license number on their website?
In several states. California requires it in all advertising (Business and Professions Code §7030.5), Texas requires the Responsible Master Plumber’s number in advertisements for plumbing work (22 TAC §367.10), Florida requires it in advertisements “regardless of medium” (§489.119), and Washington in advertising that shows a contractor’s name or address (RCW 18.27.100). Check your own state’s board.
Do I need a website for my plumbing business?
No law says so. The Federal Trade Commission tells homeowners to confirm a contractor’s license, ask for proof of insurance, search the company’s name with words like “review” and get multiple estimates before hiring, and a website is where you answer all of that at once: your license number, your photos, reviews your customers wrote and a quote form that works at night. With Onelios the cost is your time, not money.
Can customers book a plumber online through the site?
They can request a time once you save your days, hours and time zone. The start time is held and the request lands in your inbox for you to confirm; outside calendars and overlapping jobs are not checked. It suits planned work such as a water heater replacement. For a burst pipe, the Call button matters more.
Will the AI write that we offer 24/7 emergency service?
Not unless you tell it. It is instructed not to write response times such as 24/7 or same-day, or licenses, guarantees, prices or years in business, that you did not give it. It can still make mistakes, so read the draft before publishing. If you really answer at night, add it in your own words.
Should a plumbing website show prices?
Only prices you will stand behind, such as a trip or diagnostic fee, or a flat rate for a job you always price the same way. Write them in yourself: the AI is instructed not to add prices you did not give it, and nothing on the site prices a job for you. Leave work that depends on what you find, such as a repipe, to a quote.
Should a plumbing website mention the federal water heater tax credit?
Not as a current offer. The IRS says the Energy Efficient Home Improvement Credit, which covered 30% of the cost of a heat pump water heater up to $2,000 a year, applies to improvements made through December 31, 2025. Check any state or utility rebate on its own page before you mention it.
How much does a plumbing website cost?
Nothing with Onelios right now. Elsewhere, on each vendor’s own page on September 23, 2026: Siimple $10 a month for one page, Webtricity $49 a month (plus $599 if they build it), Butternut from $20 a month, Housecall Pro’s website from $99 a month plus a $99 setup fee, and Jobber’s Core plan, which includes a generated website, $49 a month with no commitment. Wix is free to create and needs a Premium plan to connect your own domain.
How long does a plumbing website take to build?
With Onelios, the AI drafts your site as soon as you give three answers (generation time varies), you review it in desktop and mobile views, and publishing needs an email address you control. Each service page you ask for is written and published when you ask. A built-for-you site takes longer: Housecall Pro says its typical build time is four to six weeks from purchase to publish.
