We had our waterline break Thursday night, and these guys answered our call on Friday afternoon Mike firmed up for a Saturday repair. Slava and his crew showed up promptly at the agreed upon time and got to work. They were courteous and very respectful of our home and property. They not only made the repair, they removed the hazardous original lead service. No easy job in the middle of a storm! Clean up was impeccable. This is without a doubt one of the best Contractor experiences we've ever had. Heavily recommend this company!

Mike and his team at WaterGuard helped me as a first time home owner upgrade and renovate my home. Sump pump and backwater valve install, trench-less main water line replacement, roughing in 2 bathrooms and a laundry room! His crews are efficient and hard working, and really do a great job. I wouldn’t hesitate recommending them for any job small or large!

These guys are freaking amazing. They came on short notice to replace my lead water intake line to the house in Hamilton. Got the job done basically half a working day and the worksite looks as if no one just dug a 4 by 4 foot hole. I’m not kidding when I mean things looked undisturbed it was literally spotless. Great work guys and thanks for the getting everything done just in time for Christmas. Highly highly recommend these guys. I will be using them again to water proof my basement as well. Yes they do that too!

I cannot give enough praise for Michael and his team. I was dealing with a major leak from the main water line and I was so fortunate to find Waterguard Plumbing. Michael and his team were very professional and reliable. Michael recognized the severity of the issue and was able to prioritize my work and had a crew on site immediately. Michael showed genuine concern by staying in contact with me from start to finish. Despite the work taking over 10 hours to complete, Michael and his team worked the entire time and did not walk away from the job without first ensuring that the work was performed beyond expectations and at the highest quality. Their pricing was very reasonable and they did not add on extra cost for having a crew on site in short notice to address the emergency service. I would highly recommend Waterguard for your plumbing and drainage needs. I have already started recommended them to my family and friends for any future plumbing needs.

This company is fanstastic and I highly recommend them. I found Waterguard on Homestars cause I had a leak problem in our basement and the plumber who did the work for the renovation was not giving me a date to come and do the work. I am so happy that I found Mike and his team. It was easy to get everything started with Mike and he came when he said he would come, same with his guys. They worked very hard and clearly explained their findings as they went along. I felt that I was given the information to make an informed decision. They did the work as promised at a reasonable price. They guys were respectful of working in our house and left the site clean. Besides a good job well done, I appreciate that Mike did not string me into any more work than what was needed, but still gave me a full assessment all the pipes in our basement and how they worked with the new ones installed.

I would highly recommend Water Guard Plumbing! Michael and his crew replaced all of the clay pipes/drains in our basement, installed a new backwater valve and upgraded our water supply line. Within 3.5 days, all of the work was completed. The crew was efficient and clean, and the best part was the price. Our quote was significantly less than other companies we had in to quote. Michael understood the strange conditions of our old Toronto neighbourhood plumbing and nothing surprised him! I would not hesitate to recommend Michael and Water Guard Plumbing to anyone that needs their drains replaced!

SEWER LINE REPLACEMENT AT MY HOMEIt is with great pleasure that I write this review for Water Guard and their dedicated team of hard workers. After a lengthy search to find the best and most reliable plumbers to replace severely tree-damaged clay sewer line pipes outside and under my basement floor, I am eagerly and happily writing this review to notify potential Water Guard customers.This team of remarkable hard workers (not to mention very considerate and kind) did an ABSOLUTELY INCREDIBLE replacement of the sewer line pipes at my home.All this work was done seamlessly during a summer heatwave. They never stopped and skillfully did the job without interruption facing the challenges of excavating through the irregular circumstances of rock-filled ground conditions, resulting in even more laborious work. They completed the entire replacement on the second day and proceeded to clean up a huge mess of rocks, roots, clay pipes, neatly re-cemented my basement floor, leaving no trace of the extensive excavation that was required. All took only 2 ½ days. Unbelievable.Mike was always approachable even throughout his busy schedule and very fair in making this cost affordable to me.This company is relentless in pleasing the customer! The GREAT reviews you read about Water Guard, Vasyl, Mike and his team are true! I give them 10 STARS!! There are many plumbers out there, but I can assure you that Water Guard is the BEST!Thanks Mike! Great guy with a meticulous team!

I have got multiple jobs done from Water Guard Plumbing so far and always received the best. Mike and crew are amazing. Patient, reliable and always delivered quality work. Talking to Mike is reassuring and you feel at ease.They replaced the water line for city requirements. Later installed weeper and valve when my basement flooded. When I needed the waterproofing, I again hired them. They leave the site clean after their work. Professional job, clear communication and well documented pictures/videos.I will always recommend them to everyone. Absolutely 5 star!
