TL;DR
Ten companies sell plumbing SEO seriously, and as of October 15, 2026, seven publish a price. Skill Mammoth (ours) runs $750 and $1,500 a month, month to month, no setup fee. Plumbing & HVAC SEO prints the fullest rate card in the trade: $2,495 a month plus a $5,000 setup on a 12-month term. Built-Right Digital publishes flat tiers at $1,499, $2,499 and $4,999 sorted by your revenue. Hook Agency starts SEO at $2,800. 1Digital runs $899 to $4,499 on a six-month term. CI Web Group starts at $1,000. Thrive says $500. Plumbing Webmasters says "$99 to start" with a setup fee and a fixed monthly rate it names on the phone, RYNO and LeadHub quote on the call, and Blue Corona, now inside RYNO, says $5,000 and up. A one-to-three-truck residential plumber should expect $750 to $1,500 a month for a program with service and city pages, Google Business Profile work and a review system. Emergency keywords move faster than remodel keywords, so the first 90 days should name a suburb and a date.
Disclosure first: Skill Mammoth sells plumbing SEO and we are ranked first below, so read our entry with the skepticism you would bring to anyone's. Every other agency here is a real competitor, named, linked and screenshotted, with its price quoted from its own page. Hook and Built-Right both publish lists like this with themselves at number one, and both rank for plumbing searches. So do we. What we can offer is a table where every row carries a published number or the words "not published," and a "best for" column that is the honest answer, which in four rows is not us.
If you want the strategy before the shortlist, the plumber SEO guide covers the emergency-versus-remodel keyword split, the service and city pages and the 90-day plan every agency here sells a version of. The wider picture, ads included, is in best plumber marketing agencies. This page is for the owner who has decided to hire out the search work and wants to know what the money buys before the discovery call.
How we ranked them
Four things, in order. Whether the price is published, because an agency that prints its number is telling you how it sells. Whether the shop knows plumbing, meaning the difference between "water heater repair near me" at 11 p.m., which is a map-pack and click-to-call problem, and "bathroom remodel plumber," which is a content and reviews problem. The contract, because a 12-month term on a plan under $2,000 should make you ask what happens at month four if nothing has moved. And the revenue band each agency is built for, which two of the ten state outright and the rest reveal in their prices.
The ten plumbing SEO companies, compared
| Company | Published price (Oct 15, 2026) | Contract | Best for |
|---|---|---|---|
| Skill Mammoth (ours) | $750 or $1,500 a month with SEO; no contract | Month to month | Residential shops to about $5M that want a flat fee with AI search included |
| Plumbing & HVAC SEO | $2,495 a month plus $5,000 setup; LSA management from $549; Google Ads $1,500 | 12 months | Established multi-truck shops in one metro that want a specialist with a printed menu |
| Built-Right Digital | $1,499 (new), $2,499 (to $1M revenue), $4,999 (to $5M), custom above | Not stated on the pricing page | Owners who want a flat tier matched to revenue and paid ads from the same team |
| Hook Agency | SEO from $2,800 a month; AEO $4,000 or $2,000 added; sites $12,000 to $24,000 | Not stated | Bigger budgets buying the name-brand contractor agency |
| 1Digital Agency | Local SEO $899 to $4,499 a month; WorkspaceCMS local campaigns $499 to $999 plus site from $89 | Six-month initial term, then monthly | Owners who want a platform and a menu instead of a retainer |
| CI Web Group | SEO, AEO and GEO agent from $1,000 a month; websites $500 to $50,000 | No contracts, 30 days' notice | Owners who want AI tooling over a team, and manufacturer co-op programs |
| Thrive Internet Marketing | SEO "starting at $500 a month"; local SEO $500 to $1,500 | Month to month | Every channel under one large roof |
| Plumbing Webmasters | "$99 to start," one-time setup fee, fixed monthly rate not published | No long-term contracts; billing starts at site launch | Owners who want a plumbing-only production shop |
| RYNO Strategic Solutions (with Blue Corona) | Not published; Blue Corona's page says "$5,000 per month and above" | No long-term contracts | $3M-plus, multi-market operations with a marketing hire |
| LeadHub | Not published | Not stated | Shops that want cost-per-lead management and SEO from one team |
| Verdict | One to three trucks: us, Thrive's local tier, 1Digital's platform or Built-Right's Essentials, and the program is the profile, the service pages, the reviews and a handful of city pages. Four to ten trucks: Plumbing & HVAC SEO, Hook or Built-Right's Launch and Scale tiers, and ask what the setup fee buys. Multi-market: RYNO. Ask the three silent ones for the number in writing before the demo. | ||
1. Skill Mammoth (ours)
Ours, so weigh it. The SEO + AI Search program comes in three published tiers, all month to month with no setup fee. Local at $750 a month covers weekly Google Business Profile management, citations on Yelp, Angi, BBB and 20-plus local directories, LocalBusiness and Service schema, two answer-first posts a month, an automated post-job review request system with responses to every review, and a baseline ChatGPT, Perplexity and AI Overviews visibility setup. Authority at $1,500 adds up to five new city and neighborhood pages a month, curated authority placements, four to six posts, a competitor gap analysis and a monthly strategy call. Pro at $3,000 adds full topic clusters, original research and digital PR. Every line item is on the pricing page so you can hold any other quote against it.
The fit is a residential plumbing company from owner-operator to about $5 million that wants local SEO, a review engine and a website built by the same team that ranks it. The site is $3,000 (or $150 a month on Easy Start), owned outright and included with every plan, which runs from $350 a month. The honest limitation is size: we are a small team with a residential focus, and a $20 million multi-market operation with an in-house marketing director belongs with RYNO or Built-Right's Pro tier. If you need the plumbing-specific site first, the plumber website design guide reviews seven real sites and what they cost.
2. Plumbing & HVAC SEO
The trades-only shop that publishes its whole rate card, fifteen years in one industry, and it deserves credit for it. The core program is $2,495 a month for one trade in one location, defined as your primary city plus ten surrounding towns, with a $5,000 one-time setup that covers competitive research, tooling, hosting and the website build. Add-ons are printed too: Local Services Ads management from $549 a month and Google Ads management at $1,500. The term is 12 months, which is the longest on this list and the thing to weigh against the transparency.
For an established multi-truck shop in one metro that wants a specialist with a published menu, this is a strong fit. For a two-truck company, the $5,000 setup alone is more than six months of a cheaper program, and the 12-month commitment means you are in for $35,000 before you can walk.
3. Built-Right Digital
A Chicago home-services agency that publishes the clearest tier ladder on this list and sorts it by your revenue. Essentials at $1,499 a month is "for new businesses" and covers listing management, core on-page and technical SEO, tracking and web management. Launch at $2,499 is "for up to $1M revenue businesses" and adds off-page SEO and a marketing support team. Scale at $4,999 is for companies up to $5 million and is the first tier with paid ads management and a monthly strategy review. Pro is custom for $5 million and up. The comparison grid underneath prints blog output per tier, 500, 800, 3,200 and 6,400 words a month. Stand-alone plans are printed too: SEO at $999 a month or $3,499 for SEO Plus, an SEO plus AEO package at $2,999, Google Ads management at $999, Meta at $1,999 and Local Services Ads at $299, with websites at $5,750, $9,590 or $14,390 one time or $599 to $1,499 a month over twelve payments.
Built-Right also runs the most aggressive content program in the category, with a page for nearly every trade-by-service combination, and their plumbing lists rank for the searches that likely brought you here. The $1,499 tier has no off-page work, so ask what moves a map pack at that price. Our Built-Right comparison has the fuller picture.
4. Hook Agency
The loudest brand in contractor marketing, Minneapolis-based, trades-only, and one of the few that prints a rate card. Local SEO starts at $2,800 a month. AEO, their AI-search product, is $4,000 standalone or $2,000 added to an SEO package. PPC starts at $2,000, Meta ads at $3,000, and websites run $12,000 for a standard build or $24,000 for custom, split over 12 months. The content team is large and their own plumbing roundups rank. The fit is a contractor with the budget who wants the shop its competitors already know by name; the setup fee and contract term are not on the page, so ask. The structural differences between Hook and us are in our Hook comparison.
5. 1Digital Agency
A different model, and the most detailed menu here. Standard local SEO retainers run Launch $899, Essential $1,599, Pro $2,499, Plus $3,299 and Premium $4,499 a month, on a six-month initial term that goes month to month afterward, with no setup fee. One-time on-site SEO comes in hour buckets at $1,699 for five hours and up. For local businesses on its WorkspaceCMS platform, local campaigns run $499, $699 or $999 a month on top of a site plan from $89, also on a six-month commitment. The fit is an owner who wants to pick from a menu and pay a platform fee rather than negotiate a retainer. The trade-off is that the platform campaigns tie the site to the vendor, so ask what you take with you.

Fifteen minutes on your trucks, your service area and your current rankings, and we will tell you which three of the ten above fit and what each should cost you, including when it is not us.
6. CI Web Group
An AI-first "marketing operating system" for the trades, plumbing included, that sells its work as agents on its own Hydra OS platform. The published numbers are scattered across the homepage: websites "from as low as $500 up to $50,000," a $600-a-month entry tier for daily blogging, an SEO, AEO and GEO agent from $1,000 a month, and marketing "up to about $3,000 per market and service category." No contracts, 30 days' notice, and no paid advertising. The fit is an owner comfortable with tooling-heavy delivery, and plumbers on a manufacturer or franchise co-op program whose sites have to follow co-op rules. Ask who touches your account weekly.
7. Thrive Internet Marketing Agency
The full-service generalist, Arlington, Texas, since 2005, month to month, with a dedicated plumber SEO page. The pricing page says SEO costs "$500 to $10,000+ per month," small businesses start "at $500 a month," and local SEO runs $500 to $1,500 with Basic, Advanced and Premium plans that carry no printed price. Plumbing is one of roughly a hundred verticals. The fit is an owner who wants every channel managed by one large vendor more than a trades specialist watching the map pack every morning. Our Thrive comparison covers the pattern.
8. Plumbing Webmasters
The pure specialist out of Fort Worth, Nolen Walker's shop, plumbers only, with its own DataPins software posting geo-tagged job check-ins to your site. The page is more forthcoming about structure than most: "our service begins with a one-time setup fee," "our fixed monthly rate does not vary by market," "there are no long-term contracts," and monthly billing starts once the site goes live, typically two to three weeks after signup, with the option to cancel before launch without paying the monthly fee. What it does not print is the setup fee or the monthly figure; the front door is a "$99 to Start! Call for Details" banner.
The depth is real after hundreds of plumbing accounts, and so is the production-line model: your site and strategy will look like other clients' sites, occasionally in your own metro. Ask about exclusivity by market.
9. RYNO Strategic Solutions, with Blue Corona
The enterprise tier. Blue Corona merged into RYNO in October 2025, so the two biggest home-services SEO brands of the 2010s now operate as one Phoenix-based shop with serious reporting infrastructure and deep plumbing case history. RYNO does not publish a price; Blue Corona's surviving pages say services "can run anywhere from $5,000 per month and above," with no long-term contracts and full ownership of everything built. The fit is $3 million and up, multi-truck, multi-market, with someone in-house to read the reports. Below that size the machinery is built for a company you are not yet, and the RYNO comparison covers what the merged shop looks like from the client side.
10. LeadHub
A San Antonio home-services agency serving plumbing, air conditioning, electrical, roofing and pest control, with SEO sitting next to a cost-per-lead management service, PPC, web development and CRM integration. The homepage leads with client results and a free discovery call, and publishes no price, minimum or plan. The fit is a shop that wants one team managing SEO and paid leads against a cost-per-lead target. Ask for the number in writing before the demo, and ask which plumbing client in your revenue band ranks today.
What plumbing SEO should cost by shop size
The published numbers sort into three bands, and the band should match your competition. One to three trucks in one metro: $750 to $1,500 a month, and the program is a correct and complete Google Business Profile, a page per service including emergency, water heaters, drains and repipes, pages for the suburbs you drive to, a review system that outpaces the two competitors above you, and schema. That band is us, Thrive's local tier, 1Digital's platform campaigns or Built-Right's Essentials. Four to ten trucks with a commercial division: $2,500 to $5,000, which adds commercial pages, more cities, authority links and a monthly call, and that is Plumbing & HVAC SEO, Hook, Built-Right's Scale tier or our Pro tier. Multi-market with five figures a month to spend: RYNO, and the question becomes reporting and attribution rather than page count. Ahrefs' survey of 439 SEO providers puts the most common retainer at $501 to $1,000 a month, so most plumbers buy the first band, and how much SEO costs has the full market ranges to check any quote against.
Five questions that expose a weak proposal
Which suburb's map pack moves first, and by when; emergency terms should move inside 90 days. What the fee is, in writing, before the demo, including the setup fee that three of the ten above charge or do not print. Who owns the website, the content and the analytics when you leave, because two platforms on this list tie the site to the vendor. Whether the agency already serves a plumber within 25 miles of you, because two clients cannot both hold the top map-pack spot for the same suburb. And what the agency does about AI search, because "plumber near me" is increasingly answered by a paragraph naming three companies. The plumbing leads guide ranks the channels SEO competes with, and Google Ads for plumbers covers the paid side of the same decision.
Frequently asked questions
How much does plumbing SEO cost?
Published prices on October 15, 2026 run from $500 a month at Thrive and $750 at Skill Mammoth, through $899 to $4,499 at 1Digital, $1,000 and up at CI Web Group, $1,499 to $4,999 at Built-Right Digital, $2,495 plus a $5,000 setup at Plumbing & HVAC SEO and $2,800 at Hook, to $5,000 and up at Blue Corona inside RYNO. Plumbing Webmasters and LeadHub price on the call. A one-to-three-truck residential shop should expect $750 to $1,500 a month.
Who are the best plumbing SEO companies?
For a residential shop that wants a flat published fee: Skill Mammoth, Built-Right Digital or 1Digital. For an established multi-truck company: Plumbing & HVAC SEO, Hook Agency or Built-Right's Scale tier. For a plumbing-only production shop: Plumbing Webmasters. For multi-market enterprises: RYNO with Blue Corona. For every channel under one roof: Thrive.
Should a plumber hire a niche agency or a generalist?
Niche shops bring pattern recognition from hundreds of contractor accounts and win on speed to competence; the failure mode is templated sameness, sometimes in your own metro. Generalists win when you want every channel managed by one vendor; the failure mode is being vertical number 37. Either way, ask who touches your account weekly and which plumbing client in your revenue band ranks today.
How long does plumbing SEO take to work?
Map pack and service-page movement in 90 to 120 days in a typical metro, compounding through months six to twelve. Emergency keywords such as "water heater repair near me" often move faster than remodel keywords because the results are more local and the competition thinner on the page. Anyone promising page one in 30 days is describing a keyword nobody searches.
Do plumbing SEO companies require contracts?
Plumbing & HVAC SEO requires 12 months and 1Digital six months. Skill Mammoth, Thrive, CI Web Group, Plumbing Webmasters and RYNO state no long-term contracts. Built-Right, Hook and LeadHub do not state a term on their pricing pages, so ask before signing, and ask who owns the site and the Google Business Profile if you leave.
Is it a problem if an agency works with my competitors?
It can be. High-volume specialists take multiple plumbers per metro more often than they advertise, and two clients cannot both hold the number one map-pack spot for the same suburb. Ask directly: do you have exclusivity by market, and who do you already serve within 25 miles of me? A shop with a good answer will give it fast. The plumbing page shows how we handle it.
