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![]()

It depends on the severity and method (excavation vs trenchless). After inspection, we give you a transparent quote.
Yes, many properties qualify for trenchless methods, saving time and landscape damage.
Small repairs can be done same-day. Full trenchless replacements usually take 1-2 days.
Not usually! We specialize in trenchless repair wherever possible to avoid major surface damage.
Our drain camera inspection will reveal the pipe condition, so you’ll get expert advice based on real evidence — no guesswork.
Basement flooding during rain indicates drainage failure or hydrostatic pressure. Professional waterproofing and drainage correction are required to prevent structural damage.
Recurring leaks mean the underlying drainage or foundation issue was never properly resolved. Permanent interior or exterior waterproofing systems are required.
Yes. Water-leaking foundation cracks worsen over time and can compromise structural integrity if not professionally repaired.
Sewer backups occur when municipal systems overload. Installing a backwater valve or repairing drainage lines is the only permanent solution.
A failed sump pump leaves your basement vulnerable to flooding. Immediate repair or replacement is required to restore protection.
Cove joint leaks occur where the wall meets the floor and require an interior drainage system—not surface patching.
Yes. Persistent musty smells signal trapped moisture and potential mold growth that must be addressed through waterproofing.
Exterior water pooling increases pressure against foundation walls and leads to leaks. Drainage correction is required.
Yes. Insurers and home inspectors often require documented waterproofing repairs before approving claims or home sales.
Finished basement damage requires immediate waterproofing to stop repeat losses and protect the home’s value.
