i called valentin when i discovered water which turned out to be sewage in my basement which continued to back up in my basement every time i flushed the toilet or showered. he came ASAP and assessed the situation. he was very pleasant and professional. and he had a crew out the next day to remove to blocked pipe and install a new one, 11 feet under ground. the workers where quick, proficient, and completely cleaned up after the job was complete. i will definitely call him again for my plumbing issues and would recommend him to anyone looking for a great plumber.
