We had leaking coming from our basement bathroom ceiling which we found out was due to an improperly installed powder room toilet. Iniitally, we got one of the big plumbing companies to give us a quote, but they thought it would be a big job, needing to cut and extend the pipe, and charged well over $400, so we balked at this. The person left our home in a huff, stating we couldn't get a better price.
Instead, we called Valentin up. It took a few days to get a hold of him, but he answered our after 4pm call. He asked me to send pictures of the problem by e-mail and within a few hours replied, stating he could do the job for almost half the price of the other company.
He was very prompt, friendly and efficient. He arrived when he said he was going to, fixed our problem in under an hour, and stuck to his quoted price. Also, he took a quick look at a couple of other minor plumbing concerns we had for no extra cost (something which the big company was reluctant to do).
It's obvious Valentin has a passion for his work and for providing the best possible service to his customers. I would strongly recommend anyone with any plumbing concerns to give him a call. It may take a few tries to get a hold of him (probably because he's very busy), but it will be DEFINITELY worth any wait!
