Trench-less technology is designed to address these issues with minimal impact on your property and maximum efficiency.






At McDowell Drain & Waterproofing, we utilize advanced hydraulic equipment and innovative techniques to replace your sewer line quickly, cleanly, and efficiently.
Pipe Inspection and Diagnosis
A high-resolution camera is inserted into the existing pipe to assess its condition, pinpoint damage, and determine the best solution.
Hydraulic Equipment Setup
Two small access points are created at the start and end of the damaged sewer line. This eliminates the need for large trenches or extensive digging.
Old Pipe Removal
The damaged pipe is broken apart using a hydraulic bursting head, which creates space for the new pipe.
Pipe Replacement
A brand-new, durable pipe is pulled into place simultaneously as the old pipe is removed. The new pipe is seamlessly installed, ensuring proper alignment and flow.




Comprehensive Assessment
Our technicians conduct an in-depth inspection using advanced camera technology to assess the extent of the damage and recommend the best solution.

We had some drainage issues and called McDowell Drain & Waterproofing. It was GREAT service, he called me right back and was here within 2 hours. Solved the problem and haven’t had any issues since. On top of great service, Stuart was very friendly, helpful and knowledgeable! I would highly recommend and will certainly be calling him for any plumbing issues we may have in the future!:)

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.

Stuart McDowell and his team deserve the five star rating! In the aftermath of the two deluges north St. Catharines experienced in August 2026 we were left reeling. Stuart responded promptly to our call for a site visit and estimates. He helped us develop and put in place a water mitigation plan for both our interior and exterior needs. Despite being run off his feet with calls across the affected region of the city, Stuart kept us in the loop. We love our 1952 vintage cottage home and McDowell Drain and Waterproofing have helped us make it able to resist the storms that will surely come in the future.Posted on Google![]()

Stu came by after we noticed hydrostatic pressure and water in the basement. He spent over an hour of his own time making sure he had the right diagnosis of what was causing the pressure and came up with the most effective and cost efficient solution. He is honest, thorough and explained his solution. Crew came by within a few days right before a major storm and they were clean and quick. No more water and we can sleep easy at night knowing we don’t have to wake up to any more surprises in the basement. Give Stu a call for any waterproofing services, I’m happy we did.Posted on Google![]()

Exceptional Service and True Professionalism! We had an outstanding experience with McDowell Drain and Waterproofing. The owner, Stuart McDowell, came out to our house personally to look at our water issue. What impressed us right from the start was his thoroughness—he took the time to completely investigate and determine the root cause of the problem before offering any recommendations. Stuart was incredibly determined to find the right, long-term solution for us. It is rare to find someone so dedicated to their craft. Beyond his technical expertise, he is a true gentleman and a consummate professional. It’s also very clear that he runs his business with high integrity; he is incredibly fair to both his clients and his workers. If you are looking for an honest, professional, and highly skilled waterproofing company, I cannot recommend Stuart and his team highly enough!Posted on Google![]()

I am writing this review to commend Stuart for his honesty. My neighbour and I had an issue with draining from our window wells. Stuart explained how the drain works and it was probably a matter of water overload rather than a plugged drain. With our lack of knowledge Stuart could have convinced us to engage in an expensive excavation. He values his integrity and we value businesses with this type of leadership.Posted on Google![]()
