I called Ara to replace a worn out cartridge in my shower and replace my bathroom sink drain. Despite the fact that these were very small jobs, Ara took my call and booked a time to come see the jobs right away. He was very professional, personable and ensured that the jobs were done quickly and correctly. All work was checked for leaks prior to him leaving and I was also told that should there by chance be a problem he would come back and fix it immediately. Ara was also willing to teach me a little bit about what he was doing and answered any questions I had about the job in case I ever wanted to attempt to tackle a similar project in the future. I have used CSI's services in the past and am a return customer. I have no problem recommending their services and would also encourage others to use their services should they be required.
