From the President: “I was negotiating a merger between a plumbing parts supplier and a service company, intending to create a national franchise. When the parts supplier withdrew, I joined the service company to enhance its financial performance.” President Myles O’Dwyer shares that his favorite aspect of working with sewer lines is the unique challenges each job presents. “Pipe work varies greatly from one location to another—even if they are adjacent—so it requires thorough investigation and problem-solving to determine the best solutions. We encounter challenges every day, which is what makes this work so fascinating. Some believe that replacing a sewer line requires digging a large trench in the yard, but our trenchless technology allows us to burst and replace an entire pipe without disturbing the surface. “Our clients truly value having that option.”

Recommended Customer Reviews

DO NOT USE THESE GUYS. They provided an estimate for a sewer lateral repair, submitted the plans to the city then did different work than what they submitted to save money. They didn't pass inspection and then wanted more money to finish the job properly. The city inspector forced them to finish the job and adjusted the plan so we could pass because they were taking so long to finish (over 2 months with open trenches). When we paid the bill they wanted 2k more than what the estimate was simply because they screwed up. This company is a total bait and switch. They city is considering not allowing them to do any more work because of their poor work, time to completion, & the bait and switch. Use Trenchless Titans. Did 2 other sewers with Gerry Hardiman and he was great, on time and on budget. Save yourself some time and grief.

My house serves as the corporate headquarters for my business, CelebriDucks (www.CelebriDucks.com). Because we returned the whole rubber duck industry back to the USA where it was invented to be the only ones making them in America once again and also now making the safest PVC free rubber ducks in the world for babies to teethe on, we get a lot film crews, reporters, clients, etc., visiting here.
So when our pipes went down and had to be replaced, we had to find a very reputable firm as the image of our company is so important to us. I did my research and I felt Pipe Spy was one of the best out there. And I was right! Their crew was just amazing. I would have to say that James, Andy, and his brother Hugo were some of the most conscientious workers I have ever met. They were just a joy to be around. They were so professional, gave us very fair pricing, and did a great job. I think anyone working with these folks will be very happy!

Pipe Spy replaced our 300+ ft. Lateral line . This was a difficult job with some very steep terrain. The crew spent some long hours using the pipe bursting system and did minimal excavation on our property. The inspector arrived with Pipe Spy walking them thru the installation approving the job. What more can you ask. Also very fair pricing compared to our other bids. Highly recommended!

Miles showed up on time and with every thing he need. Ran a camera down the line and found that a large section of 100 year old Terra cote line had been cracked by trees growing on my neighbors property and the sewer line runs through that property. They dug up the both ends of the line and ran a new plastic pipe inside to old line. Problem solved.
Very fair pricing and excellent work. Of course the pipe was most the way down a hill side so access was miserable and every thing was hand carried down to the job site..Highly recommended

Needed a trenchless lateral sewer line estimate and DVD made, Pipe Spy was very professional, on-time, and knocked $50 off the bill for early payment. Couldn't be happier.

Don't waste your time, these guys are awful.
Call others and skip this one! Do NOT believe
what they tell you either.

I am updating my review. After the issues with the video recording of my lateral line, the owner came back out, revideoed the line and returned my check. They gave me a reasonable quote to replace part of the line and shortly thereafter scheduled and completed the work. I am satisfied with the work.
I purchased an older home that needs quite a bit of updating of systems. Compared to other contractors I have hired to replace the roof, the furnace, and like work, this was not the greatest experience. But they did ultimately complete the job at a fair price.

Typically, when obtaining bids from contractors, there are many unknowns about the final costs - will the actual expenses match the bid?, will the project be completed on time?, - will the company representative be available and responsive to my phone calls and inquiries?, - will the contractor's work pass the city inspector's review?
James B. at Pipe Spy fulfilled these requirements and provided good services with excellent communication throughout the project. We had obtained other bids, but James B. was the most attentive and consistent with his work from the beginning of the job to its completion. I was impressed by his follow up after payment to verify that our landscape features had been restored to our satisfaction. Also, he was on time for all appointments.
For these reasons, I strongly recommend James B. at PipeSpy for sewer pipe inspection and upgrades.

After being told my clogged sewer line was broken and would require an $8,000 replacement, I called Pipe Spy to ask them to video the line. They said to call SF Sewer Dept. first to see if they could clear the line for free. They did so, solving the problem. Pipe Spy made no money on this. Afterwards, I asked them to video the now cleared line. They showed me a few offset joints which might over time cause a clog, but no breaks in the pipe and nothing which requires immediate attention. Thanks to them I didn't spend $8,000 on a new sewer line. Honesty, skill, and integrity are in short supply in this business, so I'm happy to have encountered Pipe Spy.

We had a sewer lateral replacement on our old Victorian with Pipe Spy last month. They were efficient, professional, dealt with all the permits in a timely way. They have a very hard-working crew who got the job done within the time we were counting on with no inconvenience to us. They stuck with their original estimate even though it took longer than they had estimated; our plumbing was old and challenging. Great customer service!
