Very professional, courteous and knowledgeable. Did a great job and takes time to explain the work. Would highly recommend Alex and his company.

Learn moreWhy local matters
A real Niagara plumber answers the phone — every time.
When you call Ottr Plumr, you reach a local technician — not a national call centre. We live in the Niagara Region, our shop is at 187 King St in Welland, and we know the housing stock here cold: century homes in St. Catharines, post-war bungalows in Welland and Port Colborne, lakeside cottages in Crystal Beach, vineyard properties in Lincoln, and new builds in Grimsby.
That local knowledge changes how we work. We know which neighbourhoods have clay sewer laterals fighting tree roots every spring, which lakeshore streets need battery-backup sump pumps, and which 1990s subdivisions are hitting the 25-year mark on their original water heaters.
Diagnose first, quote in writing, do the work clean. Every job warrantied. Every price upfront. Same-day service for most calls, 24/7 emergency response when something can't wait.

Customer love
Don't take our word for it
We were extremely happy with the excellent service we received from Alex. My wife and I called him after hours later in the evening when we were afraid of water backing up from our drains and he went above and beyond arriving quickly.

Alex is awesome, fixed everything for a great price. Will use again and highly recommend him. Thanks!
King Mike
Alex was easy to contact. With our leaking faucet and bath tub he diagnosed the problems and sourced the necessary parts quickly. The repairs were done and he made sure there were no further issues. Very satisfied with the work and will go to him for any other work we need done.
John Macpherson
Great service by Alex. Outstanding job on the replacement of the kitchen faucet. Thank you for the care and the expertise for doing a great job. Alex was amazing and friendly.

Alex came out to fix my plumbing issue (complete loss of water in house due to failing pressure tank) on short notice late in the afternoon on a Monday. He was patient, explained what was happening, provided a reasonable estimate, and did the work quickly with top quality. He also ensured he kept the work area clean and dry. I highly recommend.
