Recommended Customer Reviews

Honestly this company and the people working for them are just great. We recently had a lateral sewer replacement done by Hardiman. The company owner responded to my emails directly and they were super clear and detailed with answers to our concerns and questions. The guys who come out and do the work/ permitting etc were all so polite, professional and on it. I don't know how they find their people but they are the best!
I think the whole process from quote to work and certification took just over 1 month and with many competitors workloads and permitting processes backed-up by months that is VERY impressive.
Work took 2 days and certification happened in the afternoon of the last day. The Quote was also the lowest!
It was nice to support a local company. Thank you!

These guys went the extra mile to help me. They did the sewer lateral job well and passed inspection the first time. Then I noticed the patch on the street was crumbling. so I emailed and they had it fixed before I even had an email response!
Finally, I had a backup that turned out to be unrelated, but they came out and scoped it for me, no charge. They were amazing. Highly recommend them.

If you want a vendor who makes you feel like they're doing you a favor working on your job, look no further. You should just accept at the outset that every step of the way, from scheduling the inspection, getting a written quote, scheduling the work, confirming they are coming, finding out what exactly they are going to do, and confirming the city inspection is done and their work is finished, you will have to call them three or four times and leave messages in their black hole voicemail system. You should also accept that the only time you will hear from anyone other than their receptionist is when it's time to get paid.

I just met with technicians from Trenchless Titan. After asking a few questions I found their story interesting. The Larkspur based Company is a family owned business. The husband and wife who started it has a few young sons in their employ and has taken in other young men training them the art of Trenchless Plumbing. According to Chris the lead investigator He has been like family. He says it took many early mornings and late afternoons to learn the trade. Alex his young assistant was very polite and knowledgeable. They came with a camera snake ( free with inspection) and were able to isolate the problem and mark it out on the ground using the camera and sonar equipment to mark out the depth of existing sewage pipes. They were able to show me the video and explained the problems very clearly. The roots have intruded in the old clay pipes in various areas. This type of service, replacing old sewage pipes by threading new ones inside is a technique other companies may try to copy. Trenchless Titan has it down to a science. Another plumber told me over the phone he subcontracts them out to other clients and I should just call them. They have different teams doing different things. After the job is done they have a clean up crew who comes and can meet with inspector and put fresh gravel down when they are finished. Estimate includes County Inspection fees if they are necessary. Great company.

Getting your sewer repaired is the kind of job you want to get done once and done right. That was my logic and what drove my research when looking to have our sewer lateral repaired. I wanted to find a contractor that was very experienced and didn't cut corners (no pun Intended :)
I highly recommend Hardiman Construction (Trenchless Titan). They're an excellent outfit: very experienced, professional, and they kept to their schedule. Our sewer work was complicated but the Gerry the owner was able to speak knowledgeably about the job. We found contractors that were somewhat lower price but it's worth paying to have the job done properly and to have the peace of mind that we won't have to think about the sewer ever again.

These guys are pros and run a smooth, competent shop. They are not the least expensive bid, but they are tight, they are real people, and they do really good work. Sewer lateral replacement is a highly specific, overly regulated, and stupid expensive operation - but you gotta do it if you gotta do it. Ours was a $10k+ job up a hill with limited access and oak trees we'd rather not murder. This shop handled all with precision and care.
They also work seamlessly with, and have a good reputation with our local building/permitting agency - which is not nothing.

Cannot recommend these folks highly enough. The County had recommended that everybody in our area get their sewer laterals checked so we would not have to tear up the streets for future repairs after planned paving. I actually called another firm for the sewer lateral check (camera in the line) and they could not find the ""clean-out' spot in our unusual hilly situation, so couldn't do the check. I had already called Trenchless to get a competitive bid, and their guys found it in a matter of minutes, did a camera inspection,and found roots clogging it a bit. They drove up to get the necessary device to clear the roots, came back and did that - and ran the camera down again. They then determined our relation to the neighbors' easement &c -
The entire bill was a fraction of what the competitor had estimated to install a new clean-out.
These guys really know this subject, which is their specialty. Have recommended them to my neighbor and anybody else in earshot!

Trenchless Titan put in a new lateral to the street at our place last week. I was extremely pleased. They communicated with the City as necessary, arrived promptly, and the whole crew was very pleasant and cooperative. Most impressive, there was a glitch, and they came out ASAP and did a good job of fixing it, brick sidewalk and all.

If I could give them 10 stars I would! Trenchless Titan pulled off the impossible and replaced our sewer lateral just in time for the close on our house. Melissa was wonderful and Luke and his team worked quickly and efficiently to get the job done. I highly recommend using them!!

These guys are amazing. Wonderful family run business. We had some really bad flooding during the hard rains this winter and they came in and unclogged our drains and helped us out on very short notice. Would strongly recommend them! Thank you guys so much for helping us out.
