WE CAN HELP!

When it comes to drain repairs, sewer work, plumbing-related drainage issues, and basement waterproofing, the company you choose matters. These are not small cosmetic jobs. They often involve your home’s foundation, underground pipes, sewer connections, sump pump systems, water management, and structural protection.
Hiring a licensed and insured contractor helps protect you from unnecessary risk. It gives you confidence that the work is being handled by trained professionals who understand proper procedures, safety expectations, and local property conditions.
At McDowell Drain & Waterproofing, we know homeowners are not just looking for a quick fix. They want a company they can trust inside and around their home. That is why our licensed and insured team focuses on doing the job properly, explaining the issue clearly, and recommending solutions that make sense for your property.
Drain and sewer problems can be stressful, messy, and expensive if they are not handled correctly. A clogged drain may seem simple at first, but the real problem can often be hidden deeper in the system. Tree roots, cracked pipes, collapsed drains, grease buildup, old sewer lines, and poor drainage can all cause recurring backups.
McDowell Drain & Waterproofing provides professional drain and sewer services across Niagara Region, including:
As a licensed and insured company, we approach each job with care. We inspect the issue, explain what is happening, and help you choose the right repair instead of guessing or offering temporary shortcuts.






Basement water problems need experienced attention. Water entering your basement can damage flooring, drywall, furniture, electrical systems, insulation, and personal belongings. Over time, moisture can also lead to mould concerns and foundation damage.
McDowell Drain & Waterproofing provides interior and exterior basement waterproofing solutions designed to protect your home from water intrusion. Our team can help with:
Leaky basement walls
Foundation cracks
Wet basement floors
Weeping tile issues
Sump pump installation
Window well drainage
Exterior waterproofing
Interior waterproofing
Foundation drainage solutions
Because waterproofing work often involves excavation, foundation preparation, drainage systems, and water control, it should always be handled by qualified professionals. Our licensed and insured team brings the experience needed to protect your home properly.


Whether you own a single-family home, commercial building, rental property, townhouse, or condo complex, hiring a licensed and insured contractor gives you peace of mind.

Choosing a licensed and insured drain and waterproofing company means you are working with a contractor that takes the job seriously. It helps protect your home, your investment, and the people on your property.

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!:)
Sara Swayze
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![]()
