"The company was very fast, efficient, and very professional. I had to have my sewer pipe replaced, so they had to dig up my laundry room and bedroom floor. About a 1’1/2” wide of concrete floor They fixed the pipe and repaired the cement floor and cleaned up all of there mess. The workers were very nice and did a great job. And very far price. I’m very happy with their work. Would highly recommend this company."

"Plumber was professional, polite, and excellent. Price is outrageous. $600 for 1 hour, which includes a few Inexpensive parts. I was told it would be cheaper to buy a new toilet and have it replaced. I proxies it out: would have cost me $300-400 for a new toilet including installation. I’ll definitely do that next time."

"Tyco is simply the BEST. A company and people who are genuinely good. I couldn't ask for a better or more honest plumber. Tyler is fantastic, and Rich and Mike are outstanding. Seriously, they're there when you need them and you never have to worry about if they're being honest. This is a company that values their customers and the relationships built. Tyco has done multiple jobs for us. They've installed a tankless water heater, cleaned out drains, fixed faucets, installed toilets, and more. Seriously, if you are reading this, you're in need of a plumber. Stop looking and just call Tyco. You'll never have to search for a plumber again. Thank you, Tyco!!"

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"Waldo and his guys were honest and straightforward in evaluating my sewer problem: they told me what needed to be done and as importantly, what didn't need to be done. Another company came out and stated that the entire line had to be replaced, even though most of it is PVC since a remodel in the 90s. Waldo answered my questions directly, telling me how they would approach it and what could happen that would involve more work and therefore most cost. Even with these caveats their bid was anywhere from 20 to 60% cheaper than other bids we got. They sent me a video of the completed work showing replacement of the broken pipe as well as the rest of the sewer line. With the five year warranty, I feel peace of mind and confidence that they will stand by their work. If there is any downside, it's that they are very busy so sometimes it takes a bit to get back to you. But I never felt put off or neglected. Definitely will use them in the future for any plumbing work that comes up."

FAQs for sewer main install, replace or repair projects in Boulder, CO

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
