I don’t usually write reviews, but I felt this one was deserved. Our kitchen sink backed up late in the evening and it really worried us. At our age, these things feel overwhelming. When I called, the person on the phone was kind and patient and didn’t make me feel rushed. The plumber came out, was very respectful, explained what he was doing, and fixed the problem properly. He made sure everything was working before he left. We were very relieved and thankful for the help, especially so late at night. I would happily recommend them to anyone.Posted on Nimmy Nim NimTrustindex verifies that the original source of the review is Google. I don’t usually write reviews, but I felt this one was deserved.

Bruce was very knowledgeable and quick to diagnose the issue. Upon calling, the response is incredibly quick and arrived fast. Got a clogged kitchen drain where it is clogged at the main in the basement. Solved the problem right away and made suggestions on how to prevent it in the future. There wasn't enough for the hydrojet so they came back the next day. Brian came the next day to flush the line to make sure its clear. Very quick on picking up the history of events and is very knowledgeable. Once the flushing is done. Cleaned up really well. Pricing is good.Posted on Jeremy BaltazarTrustindex verifies that the original source of the review is Google. Bruce was very knowledgeable and quick to diagnose the issue.

We had BOS Plumbing come in for a sump pump issue at our place in Mississauga, and honestly, I’m really glad we called them. They showed up on time, explained what was wrong in simple terms, and didn’t try to scare us or upsell anything. The work was done cleanly and efficiently, and they made sure everything was working properly before leaving. It’s such a relief knowing the sump pump is now doing what it’s supposed to do, especially with all the rain we get here. Overall, very professional, friendly, and easy to deal with. I’d definitely recommend BOS Plumbing to anyone in Mississauga who needs sump pump installation or repair.Posted on Parneet JOSANTrustindex verifies that the original source of the review is Google.

Bruce got the job done but I was disappointed that he hired another company to do the work essentially taking a slice of the pie for doing absolutely nothing. And the men he hired did not speak English, they yelled and screamed at each other and were very disrespectful of our home leaving mud and dirt all over the place.Posted on kshitiz jainTrustindex verifies that the original source of the review is Google.
