Editorial Review
Our Take on Connolly's Plumbing Ltd
A tight, residential focused service list and a 4.9 rating from 751 Google reviews is a combination that usually means the basics are handled well. We like that the company publishes what it does rather than claiming everything, though that also means you should confirm scope if your job involves heating systems or anything commercial. Licensing and insurance are not stated in the public material, so ask.

About Connolly's Plumbing Ltd
Older houses on the northeast Avalon tend to fail in predictable places. Galvanised and early copper supply lines on Hamilton Avenue and around the downtown slope give up at the joints, cast iron stacks in mid century Mount Pearl bungalows scale up until a kitchen sink backs into a basement floor drain, and hot water tanks in unheated crawl spaces work harder than the manufacturer ever planned for. That is the ground connollys plumbing ltd works on, and the service list reflects it: water line repair from a pinhole leak up to a whole house repipe, water pressure diagnosis, hot water tank removal and installation, and drain cleaning with camera inspection when the cause is not obvious.
The company is based on Hamlyn Road and lists St. John's, Mount Pearl, Paradise, Conception Bay South and surrounding areas as its service territory. That is a sensible radius for a residential outfit. It covers the bulk of the metro population without stretching crews out along the Southern Shore or the Bay Roberts corridor, which usually means a shorter window between the call and the van arriving.
On the repipe side, the company says it will diagnose the problem first and recommend a course of action rather than defaulting to the largest possible job, and it offers free quotes for water line replacement. That distinction matters in St. John's, where a partial repipe of the visible basement runs is sometimes enough and sometimes a waste of money because the buried service line from the street is the actual culprit. Ask which it is, and ask whether the city side of the shutoff is involved, because responsibility and permitting change at that line.
Water heater work is described in plain terms: drain and pull the old tank, install the new one to current code, and hand over a six year warranty on the tank. The company also says it walks customers through maintenance that extends tank life, which in practice usually means flushing sediment and checking the anode rod. Anyone who has replaced a tank twice in a decade in a hard water area will understand why that conversation is worth five minutes.
Drain work is the third pillar. The equipment list covers mainlines, toilets and individual fixtures, and the company offers camera inspection for recurring blockages. Recurring is the key word. A snake clears a line; a camera tells you whether roots have found a clay joint, whether there is a belly holding water, or whether the problem is simply grease. In neighbourhoods with mature trees and older laterals, that footage is the difference between an annual call and a one time repair.
The Google Business Profile carried a 4.9 average from 751 reviews as read on September 27, 2026. Volume at that level, in a city of roughly 110,000, points to a company doing a high number of small to mid sized residential jobs. It is not proof of a good outcome on your particular job, but it does suggest the office side works, because companies that drop calls and miss appointment windows rarely hold a score that high across that many reviews. The company keeps active Instagram and Facebook pages, and it takes bookings online as well as by phone at 709-770-1331.
Who it may not suit: the published material is residential in tone and says nothing about commercial contracts, new construction rough in, boiler or hydronic heating work, oil fired systems, or septic. Homes outside the metro area are not listed either. If your job involves an oil boiler, a large commercial building or a rural well and septic setup, confirm scope before booking rather than assuming.
Before hiring anyone here, get the quote in writing with the parts spelled out, ask whether the visit carries a diagnostic or call out fee and whether it is credited against the repair, and ask about after hours rates, because a burst line in February at eleven at night is priced differently everywhere. Confirm the tradesperson's licensing status and the company's liability insurance directly, since neither is stated in the material reviewed here. For tank work, ask what the six year warranty covers and whether labour is included in a later replacement.
Compared with the alternatives in the market, connollys plumbing ltd sits in the middle band: bigger and more systematised than a one van operator, smaller and more specialised than the multi trade firms that bundle plumbing with heating and electrical. If you want a single contractor for a full mechanical renovation, the bundled firms may fit better. If you want a plumber who does supply lines, tanks and drains and does them often, this is the right shape of company.

Connolly's Plumbing Ltd FAQs
What areas does Connolly's Plumbing cover?
St. John's, Mount Pearl, Paradise, Conception Bay South and surrounding areas, according to the company's own contact page. The business is based on Hamlyn Road in St. John's. If you are further out on the Avalon, call 709-770-1331 first and confirm before booking, since the published territory is the metro area.
How good are the reviews?
The Google Business Profile showed 4.9 stars from 751 reviews when read on September 27, 2026. That is a large review count for a residential plumber in a city this size, and a high average across that many entries generally indicates consistent scheduling and communication as well as the work itself.
Do they do full house repipes or only small leak repairs?
Both. The service list runs from a small leak repair up to a whole house repipe, and the company says it diagnoses the issue before recommending a fix. Free quotes are advertised for water line replacement, which is worth using if you are unsure whether you need a partial or a complete repipe.
Can they find out why a drain keeps clogging?
Yes, they offer camera inspection of the plumbing system for ongoing drain problems. A camera run tells you whether you are dealing with roots at a joint, a sagging section holding water, or simple grease buildup, which determines whether clearing the line is a fix or just a delay.
What warranty comes with a new hot water tank?
The company states a six year warranty on new tanks it installs, with the old tank drained and removed and the new one fitted to current code. Ask directly what the warranty covers and whether labour on a future replacement is included, as tank warranties often cover the unit only.
How do I book?
By phone on 709-770-1331, by email through the address on the contact page, or through the online booking link on the website. Online booking is useful for non urgent jobs like a tank replacement quote. For an active leak, phone.
Do they handle boilers or commercial plumbing?
The published service list does not mention either. It covers water lines, water pressure, hot water tanks and drains, all in a residential context. If your job involves an oil fired boiler, in floor hydronics or a commercial property, confirm scope before you book rather than assuming.
Is Connolly's Plumbing Ltd licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does Connolly's Plumbing Ltd serve?
St. John's. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Connolly's Plumbing Ltd offer emergency service?
Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
Can a business pay to improve its profile?
A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
