"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."

"When my sewer line backed up and couldn't be fixed due to its age (installed in 1942), I made enquiries and chose the company that was most highly rated and with a reasonable cost. Jake came out and explained everything to me. He obviously knew what he was talking about. He came and had the work done efficiently and well and on-time and I am very satisfied with the company and with Jake's service."

"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."

FAQs for sewer main install, replace or repair projects in Denver, 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.
