ROTO-ROOTER PLUMBING & DRAIN SERVICE REVIEWS

I've been using roto rooter for a property I manage for over a year now and have nothing but amazing things to say. They are prompt, available 24/7 and have competitive pricing. Dianna who handles appointment booking has been beyond accommodating. The work is always done in an efficient manner. Roto Rooter St Catharines is our go to for all plumbing and drain services and will continue to be for years to come.

Hunter was our tec from Roto-Rooter , he was very professional and personable, took care of our sewer blockage and explained everything in detailed to us, and finish the job off correctly , and gave a very comfortable feeling working on my house that I did not have to keep an eye on him. I would recommend this company and this tech anytime.

Saved us on good Friday when our main drain line backed up into our basement. Problem solved in an hour total! Thank you so much to Tavon who was kind, professional, and taught us so much! He is a great guy!!!.

GO GREEN PLUMBING LTD REVIEWS

Just had Steve from Go Green Plumbing fix a leak in our basement and he was fantastic! He was kind, efficient, clean and so personable and respectful… even our dog adored him haha! This was our first time using Go Green and they now have a lifetime customer! We recognize this is not an easy job and we are just so thankful to Steve and Go Green for their outstanding customer service, work ethic and knowledge. Thanks again.

We were referred to Go Green from our designer/contract coordinator and are very pleased with their professionalism, technical knowledge and work effort. We will definitely use them for any plumbing requirements both residentially and also for my commercial buildings.

We highly recommend Go Green Plumbing!! They were excellent to deal with from start to finish! We knew up front the cost and Aaron did a great job.

COMPLETE PLUMBING REVIEWS

Excellent service! Our home septic system backed up resulting in no functioning toilets, sinks or showers, so after googling a bit I came upon Complete Plumbing. To summarize, Jamie spent the better part of a day troubleshooting, locating, repairing and resolving a broken septic pipe beneath our outdoor deck. He maintained a calm, tireless demeanour throughout the process on a day of record-breaking heat and in less than ideal working conditions.

Worth every penny. These guys were prompt, well organized and clean. I had one minor concern and it was addressed immediately above and beyond my expectations. Id definitely recommend these guys.

Great service. Jordy quickly figured out the problem and gave options to fix it. The job was completed same day for a fair price.
