They installed backwater valve and replaced drain in my house. Stu is very knowledgeable person and did a perfect job in a quick time at a very reasonable price. I would def recommend Mcdowell Drain Services to everyone in the niagara region without a doubt. Thank you Stu and team Jim Naar2025-04-01Trustindex verifies that the original source of the review is Google. Can't say enough about the quality of the experience from beginning to end. We arranged to have Stuart come out to re-assess why my parents drain had backed up before Christmas. The drain had been cleared by another company. Stuart was very thorough, kind and knowledgeable. Through the camera he sent down the sewer drain, he explained exactly what needed to be done and the time frame he could have it done. We had him over on Friday afternoon and by late this afternoon (the following Tuesday). The work was done. A section of drain had to be replaced just outside the house. The two Ivan's arrived this morning, as planned. Hand dug over eight feet down to the issue, made the repair, took pictures and closed it up. Except for the clean-out they installed, you wouldn't know that work was done that day. All the soil was piled on a tarp, and all debris taken away. Both Ivan's were very pleasant and worked hard. If we could give more stars we would. Terrific experience. Quality work. Kimberley2025-03-28Trustindex verifies that the original source of the review is Google. We had 3 drains installed and a back flow valve. From estimate to completed work, everything was completed with professionalism and was quality work. Thank you. Nancy Heckman2024-12-04Trustindex verifies that the original source of the review is Google. We recently hired McDowell Drain & Waterproofing, to repair our sewer lateral in the house. I can't praise them enough. From the first time we met with Stuart 2 weeks ago, he assured us that he would make sure that everything was fixed properly for us and at a reasonable price. We knew from speaking with him, that he was someone who stood by his word. We were blown away with the qoute, since we had a couple previous outrageous estimates. Stuart's workers were very thorough at making sure that everything was plasticed off, drop cloths laid down and all the debris removed. Very kind and respectful gentleman. Thank you Stuart , we would not hesitate to recommend your company. Thank you Stuart Howard & Nancy John McLaughlin2024-09-03Trustindex verifies that the original source of the review is Google.

David North2024-05-24Trustindex verifies that the original source of the review is Google. Professional from first contact to job completion. Job was to install a sewer backwater valve but once the floor was opened, it was evident that a sump pump installation was also required. Quickly pivoted to accommodate the additional work scope and still meet the timeline completion. Stuart, the owner is knowledgeable, professional and puts you at ease. Alex the installer did great work and paid attention to details. He was always receptive to any questions or concerns. Would not hesitate to recommend them for your plumbing needs. Lynn McDonald2024-05-03Trustindex verifies that the original source of the review is Google. We recently had basement crack leakage in two areas and a sewer backup from an obstructed sewer pipe. We called McDowell Drain & Waterproofing and it was all repaired within two weeks. Both the company and the work was efficient, professional and fair with pricing. We have had no issues since this work was completed. Extremely professional service. Highly recommend for an accountable and trustworthy repair.
