Your business depends on having reliable, durable plumbing to withstand rigorous, day-to-day use. Whether you have a small office with a single bathroom or a massive facility with specialized equipment that depends on a flowing water connection, there many not be a more often-utilized yet underappreciated plumbing device than your drains. While drains may last for years without any issues or problems, there may come a time where drains need to have a problem repaired or be replaced completely.

Thousands of Happy Customers

Was very happy with the quick response to my call for help. It was a very good experience even though it was a stressful situation. They worked with me and were empathetic to my problem and my limitations. They were very thorough in explaining the situation and what needed to be done, explaining and showing me the problem. Once it was decided what I had to do they were quick to get to work and completed the job in a very timely manner. All in all it was a stressful but good experience

– Susan C.

All Pro was awesome we called and they came the same day when our shower drain was leaking into our downstairs ceiling…..the service person was so nice and was very fast and very professional. The price was very reasonable and affordable. They did an outstanding job and we would recommend this company for all your servicing needs. This is the second time using this company, the first was for our water heater and they replaced it fast and very affordable the same day. They came at around 5 and was here until around 9 fixing not only our leaking shower drain but our water pressure value needed to be replaced. They did both and I do not think we would have gotten a better deal or a nicer person to come and do the repairs. All Pro is definitely the people we will be calling for all our plumbing, heating and air conditioning needs from now on.

They came to our rescue on January 8, 2018. we had a clogged toilet that overflowed all the way to the downstairs bathroom it was a horrific scene that day. That is when we decided to call All Pro Plumbing. Talked to a nice lady on the phone gave her our info and told us would call back to ensure us someone would come out to help. Within minutes gave us a response time and told us someone will be there within the hour. Sure enough that is when they showed up and quickly diagnosed the problem, went to work, and unclogged whatever was in there that needed to be unclogged. They were efficient, respectful, and professional. They also checkout out other things to make sure that toilet was working fine before they left. Great customer service!

– Vincent M.

Gary was absolutely amazing today. He was friendly, knowledgeable! It seemed a little pricey but our problem needed to be addressed immediately. Great customer service. I would definitely recommend!

– Danielle O.

I would recommend ALL PRO Plumbing to anyone that is looking for good professional service. They installed a sink and garbage disposal for me and did a great job. Their response time is quick. Always either the same day, or the next day

Drain Repairs

Drain lines can become damaged for a number of different reasons. The most common reason is a clog, which causes pressure to build up in a line that causes cracks and leaking. In addition to removing clogs and clearing drain lines, we can also repair leaks to keep your drain lines sealed and moving smoothly. Even a small drain line issue can be devastating for your property, and we want to prevent this serious damage from happening. We even offer maintenance services like commercial drain cleaning, video camera inspections, and more.

Drain Replacements

Over time, your drains will eventually wear out and need replaced. While a drain line may stay in place for decades without a problem, over time metal pipes can corrode, land shifting or settling can cause bends or cracks, and heavy rains or natural disasters can cause lines to collapse or fall apart completely. Replacing a drain line can be a big job—one that requires the help of a professional, so it’s best to leave it in the hands of an Ontario plumber who understands the demands of a commercial drain installation.

Commercial drain excavation is the process of digging up your drain line and replacing it with an entirely new pipe. Depending on where your drain line is located, this may involve digging up your property or even potentially breaking into the foundation of your business. While we try to avoid this option as much as possible, our skilled Ontario commercial plumbers can handle jobs of this magnitude as well if your drain line conditions dictate that it’s necessary.

All Pro Plumbing, Heating, Air & Electrical can help you take care of all your commercial drain needs! Contact us and schedule your repair or replacement today.
