I had an emergency plumbing issue that caused a flooding issues inside of my home. They responded out quickly and identified I needed to have 2-way clean out and backup prevention device installed. Mike was great in explaining what was needed to been done and why. The entire team was professional, courteous, and left the area clean and everything back in place when the job was finished. I appreciate their quick response and quality of work during this plumbing emergency. I would highly recommend them to anyone looking for a reliable plumbing company.

Reviews
We were under the gun to complete a lateral replacement in two weeks, Or we would have to leave money in escrow To complete the work. Myles and Sergio went out of their way to get this done on time, And got the certificate issued with the city also in time. They are great to work with, and they are efficient! Thank you, Pipe Spy!
Pipe Spy was awesome from start to finish. Thanks to an opening they even showed up hours earlier than the original scheduled time—huge win. They were easy to work with, negotiated the price fairly, which I really appreciated. The crew installed a brand-new sewer line in no time and had everything running smoothly without any hassle. I’d absolutely recommend Sergio the Production Manager and his crew to anyone who wants fast, professional service done right.
