Top Benefits of Basement Waterproofing Homes
In St. Catharines, basements are a necessity of homes. They provide the added storage space, additional living areas, and even
A sump pump is a mechanical pit pump installed at the lowest point of your basement or crawl space to automatically remove water that accumulates around your foundation. When groundwater, stormwater, or plumbing leaks threaten your home, the pump activates—sending water through a drainage pump discharge line away from your property. Proper sump pump installation in St. Catharines prevents flooding, mold growth, and structural damage. Pair this with our trenchless sewer replacement or clogged drain cleaning for complete protection.
Thorold’s mix of low-lying neighborhoods and clay-rich soils makes basements :
● Lake-Effect Precipitation: Heavy rains near Lake Ontario can overwhelm grading.
● Rapid Snowmelt: Spring thaw floods basements without adequate protection.
● Historic Foundations: Older homes near Allanburg and Rolling Meadows often lack modern waterproofing.
● Urban Runoff: Downtown Thorold and Pine Street corridors see rapid surface water flow — best managed with leaky basement repair solutions.
A professionally installed submersible pump system or crawl space pump keeps water at bay, safeguarding your home and belongings.

Posted on Mark Swan2025-08-28Trustindex 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 Abel2025-08-25Trustindex 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 Mansur2025-08-18Trustindex 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 Aslam2025-07-22Trustindex 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 Siciliano2025-07-07Trustindex 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!
