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:
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.

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.
