What reviewers think

Most calls go smoothly: technicians arrive on time, explain work clearly, and finish jobs quickly. Staff like Adam, Matt, Gavin, and Tom earn repeated praise for politeness and know-how, with some customers returning multiple times over decades. The rare friction arises when diagnostic work (camera, cable machine) runs high before a customer fully understands the scope, and pricing sits at the market's upper end, though reviewers note the quality often justifies it.

Emergency calls, sump pump repairs, hot water tank swaps, and toilet replacements all see strong execution. One customer had Harb solve a tight shower install others refused, and another praised a no-charge follow-up visit and warranty replacement. A small minority flag that they wish the plumber had consulted before starting expensive diagnostic runs on what turned out to be a landlord's responsibility.

Questions people ask

How quick are they for emergencies?
Reviews note rapid response and same-day scheduling. One customer reported a technician called 20 minutes prior to confirm arrival time.
Do they work on rentals or complex spaces?
Yes. Staff solved a tight crawl-space hot water tank replacement that other firms refused, and worked within tight shower spaces to avoid costly drywall or tile work.
Will they charge for a follow-up visit if the problem returns?
One customer reported a no-charge follow-up visit and warranty replacement for a sump pump that recurred; however, this may vary by situation.

For 30 years, families and businesses in Oakville and surrounding areas have called Harb back for kitchen faucets, burst pipes, and backed-up drains because staff like Gavin, Christian, and Parker arrive on time with clear estimates, finish the job fast, and leave the site spotless. The tension: skill and speed come at a price. Some pay $2100 for multiple visits to fix flooded basements; others report bills for no work done. Yet 93% of reviewers rate five stars, and the company answers emergency calls at midnight when 11 others won't.
