Comments: Kosta was both very professional and very personal. Gave me a call 30 minutes before arriving. Took a look at my problem, walked around the house a bit, and instantly diagnosed my issue. He is like the Doctor House of plumbing! He was upfront with what my costs would be, and after I approved them he went to work. He successfully snaked both an outdoor drain and one of my tubs. I am a new home opener so this was my first experience with a plumber. I had read some horror stories. Happy to say my experience was so positive I have told him will hire him again.

Comments: Arrived when he said he would, explained what he would do, did the job quickly, maybe too quickly for the price, but probably more because he knew what he was doing. Would hire again but hope I don’t need to.

Comments: Costa was very professional. He knew I needed someone right away, he gave a time when he could come and he arrived when he said he would. He told me the price up front, and though expensive, he did everything he said he would do in a timely fashion. He kept me apprised of what he was doing but kept calming my fears. He was kind and efficient, with a big smile! Thank you!

Comments: Kosta is the best plumber I have ever dealt with – and I’ve seen a few. Naturally, he does a very good and thorough job – but then, there are lots of good plumbers out there. What stands him apart is the willingness to go an extra mile – he does not assume anything, he asks, and he does lots of little things he does have to do. He also has a great spence of humour and a nice demeanor, is intelligent, upbeat, prompt, polite, and very, very clean. Not to mention, his rates are very reasonable. Overall, it has been a pleasure. I cannot recommend Kosta highly enough. I found my go-to plumber!

 

Nice Guy, Comes through as promised.  Price is little on the high side, but considering the fact that he came through in this nasty weather and is working on the pipes at 11 pm it is premium worth paying for.

I would recommend him to my clients. Not a bad way to impress a mortgage lender.

Thank you Kosta.

    We just had Kosta install new faucets in our kitchen & one bathroom. He did a great job for a reasonable price. He is also tidy, which I appreciate.
    Once again, I highly recommend him.

    Kosta is the Doctor House of Plumbing!

    Kosta was both very professional and very personal. Gave me a call 30 minutes before arriving. Took a look at my problem, walked around the house a bit, and instantly diagnosed my issue. He is like the Doctor House of plumbing! He was upfront with what my costs would be, and after I approved them he went to work. He successfully snaked both an outdoor drain and one of my tubs. I am a new home owner so this was my first experience with a plumber. I had read some horror stories. Happy to say my experience was so positive I have told him I will hire him again. He even cleaned up after himself! I have noticed not all contractors do this.

    So if you are like me and need some plumbing help, call Kosta. No need to suffer through different plumbers when you have one right here who will get the job done the first time. I am very happy.
