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:
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.

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.

Posted on Mark SwanTrustindex verifies that the original source of the review is Google. I had a sewer backup and pipe failure (the pipe is exposed in the basement, so we had sewage all over our basement). I called McDowell Drain Services based on other reviews, and he had sewerline camera equipment. Stuart McDowell, the owner, was at our house the next day to do a temporary fix on the pipe. The pipe had to be replaced, including a section of pipe outside of the house. He showed me the camera view from inside the pipe that confirmed the extent of the outside repair/replacement, to about 1.5m from the face of the building. His team came on the agreed-upon day and time. The team worked very hard and did an excellent job, including cleanup, all in a day, thus limiting downtime for our use of the sewer. I recommend McDowell Drain Services based on our experience.Posted on Antal AbelTrustindex verifies that the original source of the review is Google. Stuart and his team are the best. They are the only plumbers in all of Niagara to offer trenchless drain replacement saving me thousands on digging up my front lawn. He has also installed a sump pump system in my basement as well as a full bathroom rough-in and waste pump. The work was done professionally and in a timely manner. Stuart is quick to respond to my queries and takes pride in his work. There is no question- Stuart is the first guy I call if I ever have a plumbing issue, big or small!Posted on Chris MansurTrustindex verifies that the original source of the review is Google. McDowell Drain & Waterproofing is my go-to company for any drainage issues. I wouldn’t call anyone else. This is now the second time I’ve used their services and both times the service was exceptional. Stuart is one of the nicest and most honest, knowledgeable, and reliable professionals I’ve ever dealt with. Both times that I had flooding issues, he was quick to respond, gave very reasonable quotes, finished on time, and provided services that exceeded my expectations. He also ensured I was happy with the service at the end. I’ve even had other contractors on unrelated issues tell me how good the quality of work is with the water mitigation system that he installed. 5/5 stars!Posted on Adina AslamTrustindex verifies that the original source of the review is Google. Stuart was so helpful form the start. He not only gave me an accurate quote over the phone, but also followed through and charged me the exact amount that was quoted initially while other companies would charge a service fee to even come out and look at the issue. He provided same day service. He spent several hours in fixing the kitchen drain and cleaning it out, but charged a very low amount for his labour. He sent me photos of the issue, kept calling me throughout the process to explain the steps he was taking to fix it and then cleaned up before he left. It was a really tough mess stuck in the pipes that would’ve cost me twice to get it cleaned by someone else. I appreciate the honesty and excellent customer service he provided me with throughout the process. I can’t say enough good things about him. I will for sure be calling Stuart for any of the future plumbing needs. Thankyou for resolving this issue promptly and doing it so professionallyPosted on Ryan SicilianoTrustindex verifies that the original source of the review is Google. We had a sewage issue and Stuart quickly answered the call and cleared the pipes. He then quickly located the problem. He assured me that he would soon have a crew out to resolve the issue. He told me I could call him if anything came up before workers arrived. Contacted me on which was a Sunday and said a crew would be out Monday morning which they were! Where the sewer needed to be replaced was below my porch into the basement. The crew Alek and Igor dug by hand. This was even more laborious job due to the thick clay in our area. The job was completed and work site cleaned up impeccably. I am thankful to Stuart for his immediate attention and honest assessment! Also for the great crew he provided. They were professional, respectful and cheerful through the duration of the grueling and unpleasant work they have to deal with. Thank you so much!! Update...Called Stuart as having sewer smell in basement. He came over immediately and found the issue. There was no cap on a drain from a previous installation that he hadn't done. Stuart went out to Home Depot purchased a drain cover, returned and replaced it! His immediate responses and kindness go above and beyond! I am so very grateful! Gaye SicilianoPosted on Lynn HarrisTrustindex verifies that the original source of the review is Google. RESPONSIVE. KNOWLEDGEABLE. AFFORDABLE. AMAZING. I chose McDowell Drain and Waterproofing based on reviews, and I am happy to say I had the same great experience as many others! Stuart is a true pro - responded to our request right away, and came out the next day. He explained everything and showed images of the issue, and within the week his crew was working on our drain repair. His crew was amazing and went above and beyond our expectations. Highly recommended!Posted on Prabh SandeepTrustindex verifies that the original source of the review is Google. Highly recommend this waterproofing team in Niagara!
