Editorial Review
Our Take on Harb Plumbing
The service list reads like a company that has genuinely done this for decades, covering the awkward jobs, main sewer lines, Kitec replacement, backwater valves, that plenty of firms would rather hand off. A 4.9 average across 581 Google reviews is a lot of feedback for one Mississauga address, and it points to consistency rather than a lucky run. Get after-hours rates and permit responsibility confirmed on the phone before the truck is dispatched, and this is a sensible shortlist entry.

About Harb Plumbing
Harb plumbing runs the kind of service list that tells you it has been around a while. Drains and main sewer lines sit at the front of it, alongside camera inspection, backwater valves and backflow preventers, sump and sewer pumps, hot water tanks, toilets, faucets, sinks, showers and tubs, basement rough-ins and pipe replacement in Kitec, PEX, copper, cast iron and lead. Then there is the renovation side, complete bathrooms and kitchens, supported by a design showroom on Dundas Street West that the website says is open by appointment only. That combination, emergency repair on one hand and planned interior work on the other, is not the norm among smaller plumbing firms.
The Mississauga context matters here. Housing stock across Cooksville, Erindale, Lorne Park and the older pockets near Dundas ranges from postwar bungalows with clay or cast iron laterals to 1990s and 2000s builds where Kitec was used for potable water and in-floor heating before the class action settlement. Those two eras produce very different calls. The older homes bring root intrusion, offset joints, sewer backups after heavy rain and basement drains that need camera work before anyone quotes a dig. The newer ones bring failing brass fittings and pinhole leaks in the grey or orange Kitec pipe, and a decision about whether to repipe the whole house or patch and wait. The company names both types of work directly, which is a reasonable sign that it deals with them regularly rather than referring them out.
Stormwater and basement flooding are the other Mississauga specialty. The City and the Region of Peel have run subsidy programs for backwater valve and sump pump installation in flood-prone areas, and that work involves a plumbing permit, an inspection and often a floor break in a finished basement. If that is the job you are calling about, ask directly whether the quote includes the permit, the concrete work and the restoration afterwards, and ask who handles the paperwork if you are applying for a rebate. Those details separate a fair price from a low one.
For emergency work, the published hours show open 24 hours every day of the week and the company markets a round-the-clock response. Treat the hours as a phone that gets answered rather than a promise of an instant truck. Reasonable questions before you agree to a night or weekend visit: is there a call-out or diagnostic fee, does it get credited against the repair, and what does the after-hours rate look like against the daytime rate. Any established plumber will give you a straight answer to that on the phone.
The review record is the strongest piece of independent evidence available. Its Google Business Profile carried a 4.9 average from 581 reviews when checked on September 18, 2026. Volume at that level, from one address, generally reflects years of steady residential work rather than a marketing push. The 1974 founding and the family ownership are claims made on the company's own website and should be read as such, though a five decade history in the same trade corridor is consistent with the review count.
Who it suits: homeowners in Mississauga and the neighbouring Halton towns who want one firm handling the drain emergency, the water heater swap and, later, the bathroom rebuild, with fixtures they can look at in person before committing. Landlords and small commercial properties are mentioned on the site too. Who it suits less: anyone chasing the cheapest possible clear of a kitchen drain, and anyone needing gas, HVAC or electrical work, which does not appear in the published list. If your job is a straightforward furnace or air conditioning issue, that is a different trade licence.
Compared with the alternatives in this market, Mississauga has no shortage of plumbers, from national franchise operations with flat-rate books and heavy advertising to one-van independents who answer their own phones. Harb plumbing sits between those poles: local ownership and a long trading history, but with the showroom, service plans and client portal you would normally associate with a larger outfit. Ask for the quote in writing, ask whether the technician attending is a licensed journeyperson or an apprentice, and confirm the warranty terms on both labour and any supplied fixture. On larger sewer or repipe work, a camera recording or photographs of what was found is worth requesting before anything gets covered back up.

Harb Plumbing FAQs
Does Harb Plumbing actually answer the phone at night?
Its published hours show open 24 hours, seven days a week, and the company markets a 24/7 emergency service. That means the line is staffed around the clock rather than guaranteeing a van at your door within a set time. Ask on the call what the expected arrival window is and what the after-hours rate will be.
What areas does it cover?
The website lists Mississauga, Oakville, Burlington, Milton, Hamilton, Etobicoke and Waterdown, with separate pages for Mississauga south. The physical address and showroom are at 2400 Dundas St W in Mississauga. If you are at the far edge of that range, confirm travel and response expectations before booking an emergency call.
Can it replace Kitec pipe?
Yes, Kitec replacement is named directly on its service list, along with PEX, copper, cast iron and lead. Kitec was installed in many Mississauga and Halton homes built roughly between 1995 and 2007, and the brass fittings are the usual failure point. Ask whether the quote covers a full repipe or targeted sections, and how drywall and restoration are handled.
Do I need a permit for a backwater valve or sump pump?
Backwater valve and sump pump installations in Ontario generally require a plumbing permit and an inspection. Confirm with the company whether the permit, the concrete cutting and the patching afterwards are inside the quoted price. Peel Region and the City of Mississauga have offered subsidies for this work in the past, so ask who handles that application.
How reliable are the reviews?
The rating is 4.9 from 581 reviews on its Google Business Profile as read on September 18, 2026. That is a large sample for a single-location plumber, which makes the average more meaningful than a high score built on a handful of reviews. Reading the most recent dozen is still worth the five minutes, particularly for comments on pricing and follow-up.
Can it handle a full bathroom renovation, not just repairs?
Yes. Complete bathroom and kitchen renovations are listed alongside the repair services, and there is a design showroom at the Dundas Street West address for choosing fixtures, open by appointment only. Brands named on the site include Moen, Riobel, Delta and Kohler. For a full renovation, ask about the scope of any tile, electrical or drywall trades involved and who coordinates them.
How long has Harb Plumbing been in business?
Its website states the business has been a local family-owned plumbing and drain service since 1974. That is the company's own claim rather than independently verified, though the volume of Google reviews is consistent with a long trading history in the area.
Is Harb Plumbing 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 Harb Plumbing serve?

Does Harb Plumbing 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?
