No plumber in Hamilton has collected more Google reviews this year than JT Carter Plumbers: 134 by 1 November, seven more than Optiplumb. Yet in a desktop search for “plumbers in hamilton nz” that morning, JT Carter appeared below several plumbers from Hamilton, Ontario. Google’s copy of its home page calls it “Plumbers Te Aroha”, after its other branch. And almost one review in four mentions a washing machine, a dishwasher, an oven or another appliance. We read all 438 reviews of the Hamilton profile and 54 of the Te Aroha one for the third review in our series that follows the guide to plumbers in Hamilton.
The short version
- JT Carter Plumbers works from Frankton in Hamilton and from Te Aroha: plumbing, gasfitting, drainage, roofing, heating, chimney cleaning and kitchen and laundry appliance repairs.
- Hamilton profile: 4.9 from 438 Google reviews, 149 in the last 12 months. Customers praise speed (177 of 393 written reviews), friendly staff (112) and appliance repairs (89).
- The business started replying to reviews on 31 December 2025 and has answered almost every review since, after more than 300 went unanswered.
- Rare for the trade: a published price list, with every rate before GST and separate lines for the vehicle fee, the jetter, travel and the appliance technician.
- SEO4 Audit Score: 18 out of 30. Reviews 6, search 4, marketing 8. Six checks scored 0 only because the website’s security check blocked our browser.

What 438 reviews say
The Hamilton profile’s first review is from November 2020, but the record really starts in 2022, with 81 reviews. Then 66, 65 and 90, and 134 so far in 2026. Nine in ten give five stars. Speed comes first in the written reviews (177), often “under an hour” or the same day, then friendly staff (112), communication (60) and professional work (54). Price comes up in 45, mostly as fair.
Until the end of 2025 nobody answered. The first reply from the business is dated 31 December 2025, after 303 reviews had gone without one. Since then it has replied to 128 of the 134 reviews written in 2026, and the replies read like a person wrote them: the customer’s name, the job (“the leak under the basin”, “your repeat chimney clean”) and sometimes the technician. The six without a reply are all from the last nine days.
One thing is missing from the reviews: names. Thomas appears in 22, more than anyone else, but fewer than one review in ten names a person at all. In a team this size, that is a lot of good work nobody can ask for again by name.
The appliance side
Eighty-nine written reviews mention an appliance, and 60 of them a washing machine. Dishwashers (19), ovens and cooktops (14), dryers and fridges follow. Washing machines are by far the biggest single job in the reviews, and appliance work hasn’t slowed: in the last 12 months, 28 of 134 written reviews were about appliances.
JT Carter has an appliance repair page and separate pages for kitchen and laundry appliances, and its price list has an “appliance technician charge”. Among the Hamilton plumbers in our guide, no other business’s reviews lean towards appliances like this.
Both ends of the hose
A plumber who also fixes washing machines is the only tradie who can blame the leak on the appliance and then fix the appliance.
The low ratings
Five of 438 reviews give three stars or fewer, and two of them don’t seem to mean it. A one-star review from August 2026 reads, in short, “always awesome service”, and a two-star review from June praises a knowledgeable technician. Both look like a mis-tap on the stars. The business thanked both, which is polite, but a short note inviting the customer to fix the rating would help them and the average.
One complaint is real. In June 2026 a customer paid $143 for an appliance assessment that took minutes, then waited seven working days for a short written report and had to chase it; the reply said the business had reviewed its communication. A three-star review from 2024 calls the service great but the part “more than my machine”. The last is a three-star rating without text. A four-star review from May describes a booking made on the phone on the office’s assurance about which washing machine brands it repairs. The pattern points at the appliance desk, not the plumbing: what the assessment costs, which brands are covered and when the report arrives.
A price list, at last
Here JT Carter does something none of the other Hamilton plumbers we have reviewed does. It publishes a price list. As Google shows it, the page sets out standard rates, all before GST, for plumbing and drain laying and for gas fitting, then an after-hours call-out and other charges: a service vehicle and admin fee, drain unblocking with a jetter, out-of-town travel and an appliance technician charge.
Google’s top question for this trade is what a plumber charges per hour, and this page answers it. Two small changes would make it work harder. Show the GST-inclusive figure next to each rate, because that is what customers compare. And put a typical appliance assessment, with the time to a written report, on the appliance page, where the one real complaint started.

JT Carter Plumbers publishes a price list, with every rate before GST and separate lines for extras. Choose your job and see a budget at Hamilton market rates, and which lines of the list to read before you ring.
Budget: market rates from SEO4’s guide to plumbers in Hamilton (October 2026), not JT Carter prices. Weekday first hour $130 to $145, extra hours $90 to $105; after hours first hour $200 to $260, extra hours $160 to $220; all plus GST, parts extra. The headings of JT Carter’s price list (plumbing and drain laying, gas fitting, after-hours call-out, service vehicle and admin fee, drain unblocking with a jetter, out-of-town travel and an appliance technician charge) are as Google showed them on 1 November 2026. The $143 appliance assessment is from one customer’s review in June 2026. A guide, not a quote.
How the check works
The budget uses the published rates in our guide to plumbers in Hamilton, not JT Carter’s own figures, because our browser couldn’t open its price list on 1 November 2026. The price list’s headings are as Google showed them. Read the list itself before you book: every rate on it is before GST.
How it compares in Hamilton
On review numbers, JT Carter and Optiplumb are the two big names in Hamilton plumbing. Over the last 12 months they added 149 and 151. Nobody else comes close: KZN Plumbing added 47 and iPlumber 12. JT Carter has the most reviews written in 2026 of any plumber in our data.
The map doesn’t reflect that. On 31 October a desktop search for “plumbers in hamilton nz” put Optiplumb, KZN Plumbing and iPlumber at the top of Google’s list. On 1 November JT Carter appeared further down, below several Canadian plumbers with +1 numbers. On 23 October it wasn’t in the map’s top three either. Reviews are only one signal. Google also reads the website, and JT Carter’s home page title is about Te Aroha.
Two profiles, two speeds
The Te Aroha branch has its own Google profile, “JT Carter Plumbers & Hardware”, with 54 reviews averaging 4.54. It collected four reviews in the last 12 months and answered none; its last reply is from 2025. The same business runs both, so the same habit of asking and replying would lift the smaller branch.
SEO audit
This part is mostly for the business and other tradies. If you need a plumber, jump to the common questions.
The brand search
Type “jt carter” and Google’s suggestions mix the plumbers with a baseball player, an actor and a singer who share the name. Add “plumbers” and they become useful: “jt carter plumbers hamilton”, “jt carter plumbers te aroha”, “jt carter plumbers & hardware reviews”, “jt carter appliances”. People search for the appliance side by name. For “jt carter plumbers” the website comes first, then Facebook (more than 1,000 followers), Instagram and directories. No competitor advertises on the name.
The Google profiles
The Hamilton profile is “JT Carter Plumbers Hamilton”, category Plumber, with real photos of finished laundries and bathrooms, the 0800 582 278 number and weekday hours, closed at weekends. Two things don’t match. A JT Carter Facebook page, as Google shows it, lists 0800 572 278, one digit different, and says 24/7. Several reviews describe Saturday, Sunday and public holiday call-outs. One phone number and one honest answer about weekends, in every place, would stop people ringing the wrong number or the next plumber.
The website
We couldn’t look at jtcarterplumbers.co.nz ourselves. On 1 November 2026 a Cloudflare security check stopped our browser, and we don’t try to get around those. Google’s index of the site shows a lot to like:
- Service pages for Hamilton: plumbing, gasfitting, backflow prevention, roofing and solar hot water, plus drainage, water tanks, heating, chimney cleaning and appliance repairs.
- The price list, a warranties page and a page on the Master Plumbers Guarantee, which the site says covers up to $20,000 including GST.
- A team page, a history page and careers pages advertising for a plumber and a roofer in Hamilton.
And a few things to fix:
- The home page title, as Google shows it, is “JT Carter Plumbers | Plumbers Te Aroha”. Most of the reviews and searches are about Hamilton.
- If the security check that stopped us ever reaches real customers or Google’s own tools, such as PageSpeed Insights, it costs visits. It is worth checking how strict it is set.
- We couldn’t check the H1, meta description, schema, tap-to-call or speed for this reason. We will add them if the business lets us know.
Spare key
Reviews say JT Carter also cuts keys. Handy, if the plumber ever needs to let himself back in.
SEO4 Audit Score: 18 out of 30
The same thirty checks we use for every business we review. They measure what customers and Google can see online, not the plumbing. Six checks scored 0 only because we couldn’t open the website or confirm recent social posts, so the real score is probably higher. Optiplumb and iPlumber scored 21. This is a different scale from the Local Score in our guide.

A plan for more jobs
JT Carter has the review pace and the price list. Turning that into map visibility in Hamilton is mostly about telling Google where the work is.
| What | Why | Effort | Likely effect |
|---|---|---|---|
| “Plumbers Hamilton” in the home page title and heading | Google shows the home page as “Plumbers Te Aroha” | Very low | High |
| Check the security wall lets Google’s tools and every customer through | It stopped our browser on 1 November | Low | High |
| One phone number and one answer on weekends: Google, website, Facebook | 0800 582 278 against 0800 572 278; “closed” against 24/7 | Very low | High |
| An appliance page built for “washing machine repair Hamilton” | 89 reviews mention appliances; people search “jt carter appliances” | Medium | High |
| Ask the two mis-tap reviewers to correct their stars | A one-star and a two-star with glowing text | Very low | Medium |
| Publish the assessment fee and report turnaround for appliances | The one real complaint | Low | Medium |
| Ask and reply on the Te Aroha profile too | Four reviews and no replies in a year | Low | Medium |
| Name the technicians on the team page and in the booking text | Fewer than 10% of reviews name anyone | Low | Low to medium |
Ideas that fit this business
- Sell the double visit. “Plumber and appliance technician, one call” is a promise no Hamilton competitor makes; put it in the first line of the home page and the Google description.
- Write up the save-or-replace question. A short guide on when a washing machine is worth repairing, with the assessment fee, would rank, answer the price complaint and bring appliance jobs.
- Show the price list off. Few tradies dare to publish rates; a line on Google posts and Facebook saying “our prices are online” is free trust.
- Keep the review habit going. The 2026 replies are good; asking for a name in the review (“Who came to you today?”) would build the team’s reputation as well as the company’s.
