Plumbing Repairs
Our licensed plumbers handle all residential and commercial plumbing needs, from emergency leak repairs to full system installations. We specialize in sump pump replacements, backflow prevention, and sewer line repairs using advanced diagnostics. With 24/7 availability, we ensure minimal disruption to your property while delivering durable solutions that meet local code requirements.
Basement Waterproofing
We provide comprehensive basement waterproofing solutions including exterior foundation sealing, sump pump installations, and French drain systems. Our team addresses water intrusion at its source, using proven methods to protect your property from flooding and structural damage. All waterproofing work comes with a 20-year transferable warranty for long-term peace of mind.
Sewer Cleaning
Our sewer cleaning services utilize high-pressure jetting equipment to clear blockages in lines ranging from 1.5" to 30" in diameter. We offer routine maintenance and emergency clearing for residential and commercial properties, using pipeline video inspections to identify root intrusions, cracks, or collapses. This non-invasive approach minimizes repair costs and downtime.
Hydro Vac Excavation
We employ Hydro Vac technology for precise, non-destructive excavation around underground utilities. This method uses high-pressure water and vacuum suction to safely expose pipes and cables without damage. Ideal for utility location, trenching, and debris removal, our Hydro Vac services reduce project timelines while maintaining site integrity.
Stormwater Management
Our stormwater management services include catch basin installation, dry well construction, and retention pond development. We design systems to prevent flooding and erosion while complying with municipal regulations. Regular maintenance programs ensure optimal performance of stormceptor systems and drainage infrastructure for commercial and municipal clients.

Report
I contacted Best Plumbing and Drainage Contractors in late summer 2020 to provide a quote for some drainage issues we had in our backyard. Shawn was able to come and provide a quote with a plan on how to add drainage to the yard with catch basins to provide drainage in the winter months. They were able to come and complete the work in late 2020. A year later, we have had no drainage issues and the small pond we used to get after rain no longer exists. I strongly recommend Best Contractors for their amazing work and also great support. Shawn is very knowledgeable and is a business owner who really

I had tree roots growing into my sewer line. I made the mistake of calling another plumbing company first, which did not fix the problem. Shawn returned my email quickly on the weekend and sent Tyler over to my house. Tyler did a fantastic job clearing the pipes & is a great guy. I highly recommend Best Plumbing and Drainage Contractors.

USE BEST FOR EVERYTHING!! Our basement flooded in July 2020. As part of the rebuild, the city of London has a grant program to assist in putting in a sump pump, backup system, and backwater relief valve. They require two quotes be submitted. I called around, and spoke to 6 plumbers, and obtained three quotes. I decided to use Best instead of the other companies because the owner Shawn came out personally to do the quote. He treated me with a respect not found in the other companies. He answered my questions, was patient with my subsequent emails, and never once did I feel like an inconvenience

I called to report a leak in my basement. Sean was over the next day, assessed the area and showed me the crack in the exterior concrete wall causing the water in my basement. He could have easily told me that they could start the job and pocket the money after they fixed the problem. Instead, he gave me another cheaper option and saved me thousands of dollars. He made nothing on his visit but referred me to someone else who could fix the problem for a portion of the price. I am very pleased to see that this type of honesty still exists today. Thanks Sean!

Had basement drainage blockage. Called Best Plumbing and drainage and they arrived as promised. Service man great to deal with and got the problem solved in a timely manner. Previously had work done by the same people and were always fair and good to deal with.
