WE CAN HELP!
Drain, sewer, plumbing, and basement water issues can go from “small problem” to “major damage” very quickly. A slow drain can become a complete blockage. A small foundation leak can turn into a flooded basement after heavy rain. A sewer backup can create an unsafe and stressful situation for the whole household.
That is why McDowell Drain & Waterproofing provides emergency services for homeowners, property managers, and businesses throughout the Niagara Region. When you need urgent help, our goal is simple: respond quickly, diagnose the issue properly, and give you the right repair before the damage spreads.
Blocked or damaged drains are one of the most common reasons customers call for emergency help. If water is not draining properly, it can back up into sinks, tubs, floor drains, laundry areas, or basements.
Our emergency drain services can help with:
A clogged drain is not always just a surface blockage. In many homes, especially older properties in Niagara, the real issue may be deeper in the drainage system. McDowell Drain & Waterproofing uses professional inspection and repair methods to identify what is happening and recommend the best solution.
A sewer backup is one of the most urgent drainage problems a property owner can face. It can bring wastewater into the home, create odours, damage flooring and walls, and expose your family or tenants to unhealthy conditions.
Call McDowell Drain & Waterproofing right away if you notice:
Sewage backing up into a basement drain
Gurgling toilets or drains
Multiple drains clogging at the same time
Strong sewer smells inside or outside
Water pooling near the foundation
A toilet that will not flush properly
Wet areas in the yard near the sewer line
Our sewer services include sewer camera inspection, drain and sewer repair, trenchless sewer replacement, and backwater valve installation. We focus on finding the cause, not just clearing the symptom, so the problem is less likely to return.
Plumbing problems often happen at the worst possible time. A sudden leak, burst pipe, backed-up fixture, or failed drainage connection can cause immediate stress and expensive property damage.
McDowell Drain & Waterproofing helps with urgent plumbing-related problems connected to drainage, sewer lines, sump pumps, and water entering the home. If your plumbing issue is causing flooding, backups, water damage, or drainage failure, our team can inspect the situation and guide you toward the right repair.
Common emergency plumbing issues include:
A wet basement should never be ignored. Water entering through walls, floors, window wells, foundation cracks, or weeping tile systems can damage finished spaces, create mould concerns, and weaken the long-term protection of your home.
McDowell Drain & Waterproofing provides emergency basement waterproofing support when water is actively entering your property or when repeated leaks keep coming back.
We can help with:
Our team looks at the full water problem, including grading, drainage, sump pump performance, foundation condition, and waterproofing needs. The goal is not only to dry the basement today, but to help prevent future water damage.
When you are dealing with water, sewage, or a flooded basement, you need a company that understands the urgency and knows how to solve the problem properly.

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.
