WHAT EVERYONE IS SAYING
EXCELLENT Based on 1280 reviews Posted on Google Ted UrbanowiczTrustindex verifies that the original source of the review is Google. Excellent service and competencePosted on Google Gord BirnieTrustindex verifies that the original source of the review is Google. I had a leaking galvanized pipe in my basement, I called Birnie plumbing and spoke with Tim. He was very polite and professional. The next day Chad, the technician came and gave me a suggestion on how to resolve the problem. Once I chose which option to use he gave me a quote that was acceptable. Chad was professional and educated me on the procedure that he was undertaking. He explained and showed me how and why he was doing the job that way. This was our second experience with Birnie plumbing and both times the service was exemplary. Their professionalism is second to none. Thanks for the easing us through the experience.Posted on Google Noor STrustindex verifies that the original source of the review is Google. I contacted staff to have a plumber come check our wall ceiling to confirm that there is no water leak from the washroom. Staff assigned Tim the professional plumber to come next morning and he was at my place at 9 30pm. He investigated the level 1 and concluded that there's no issues at all and when I asked for a written report of his inspection, it was sent my way within the hour. I am very pleased with their customer service and the professional work. Thank you Tim and all the staff I highly recommend their businessPosted on Google Shirley DelaneyTrustindex verifies that the original source of the review is Google. I was in a panic over water in my basement. I called Birnie and right from Don, who set up the appointment, to Monica who called to confirm, and then technician Jamie completing the work it was such a positive experience! Jamie took the time to explain everything and made sure I was satisfied with the work every step of the way. Highly recommend the Birnie team!!Posted on Google DeniseTrustindex verifies that the original source of the review is Google. 5 stars for Dylan at Birnie Plumbing & Drains! He was incredibly helpful and took the time to give super thorough explanations of everything he was doing. It’s rare to find that kind of honesty in the trade. Best of all, once the job was done, we were finally left in peace. Highly recommend asking for him!Posted on Google Alexandra HibbardTrustindex verifies that the original source of the review is Google. Birnie’s is always fantastic! I had a slight back up, coming up from my basement floor drain on Sunday night and they were there first thing Monday morning! Special shoutout to the technicians Eric and Jamie, they were friendly, and informative. They explained exactly what was going on and had it sorted in no time! Highly recommend them!Posted on Google Tricia Minor-BretonTrustindex verifies that the original source of the review is Google. After many years of our sewer backing up and multiple plumbing companies coming in and out. I finally called Birnie and sons. Rob came out explained and showed me what was going on with our main sewer line. He was the first person after many headaches that told us we had a shared sewer line. After dealing with the city to do their part so we could have our own sewer line put in, Rob kept me up to date with everything. Had his locates ready to go, once the city finished they started asap. He said it would be a 3-4 day job. Done in 3. It was a huge job!!!! Very professional, communicated and left the job site as clean as it could be. (basement had to be dug up). I am so glad I called this company and would highly recommend them. I will never call another plumbing company again! Thank you Rob, Birnie & son's!!!!Posted on Google John GTrustindex verifies that the original source of the review is Google. We had a sewer back up and called Thos R Birnie Lake Ave Hamilton. Service rep, Jamie cleaned brush and weeds from pipe and followed through with a video of the pipe from the house to the city connection. He was courteous and knowledgeable. Ensured the blockage was clear and provided printed costs for that service. A follow up visit was made by Robert who gave us a printed detail with costs of our options going forward. Very professional. Can't say we were happy about the cost to repair, but the details were provided for us to review.Posted on Google Graham DavidsonTrustindex verifies that the original source of the review is Google. Chad D showed up right on time, diagnosed our issue quickly, set out an easy and fair pricing plan for the job, and fixed a leak that was causing a lot of damage. Really appreciated his work and explaining what needed to get fixed. We’re all set and leak free now. Highly recommendPosted on Google Jacqueline FraserTrustindex verifies that the original source of the review is Google. Mike was so professional and he had everything done right on time.

Thorold Local Infrastructure & Plumbing Systems
Understanding Thorold’s history, escarpment geography, and infrastructure helps explain the plumbing and drainage challenges many homes experience today.
Historic Canal City & Escarpment Infrastructure
Thorold is one of Niagara’s oldest communities, shaped heavily by the Welland Canal, escarpment geography, and decades of residential expansion. The city features a mix of historic homes, established neighborhoods, and newer developments with varying plumbing and drainage conditions.
- Older cast iron and clay sewer systems
- Aging copper and galvanized water services
- Drainage challenges tied to escarpment elevation changes
- Stormwater concerns near lower-lying areas
- Tree root intrusion in mature neighborhoods
Homes throughout downtown Thorold, Confederation Heights, Allanburg, and established residential areas often experience sewer backups, slow drains, and underground infrastructure wear related to aging systems and soil movement.
Escarpment Soil Movement
Clay-heavy soils and elevation changes near the Niagara Escarpment can place stress on underground sewer and water lines over time.
Historic Neighborhood Infrastructure
Older areas throughout Thorold often still rely on aging plumbing systems that may now be approaching the end of their service life.
Canal & Groundwater Conditions
Areas near the Welland Canal and lower elevations can experience higher groundwater levels and increased drainage system pressure.
Modern Residential Expansion
Newer subdivisions feature updated plumbing systems, though grading, sump pumps, and stormwater management remain important considerations.
Tree Root Intrusion
Mature trees throughout established neighborhoods frequently contribute to root intrusion in sewer laterals and underground drainage systems.
Basement Water Protection
Heavy rainfall and varying elevation levels make sump pumps, waterproofing, backwater valves, and weeping tile systems important for many homes.
