"My service technician today was Ken and he was very professional and friendly! He gave me various quotes and fixed the toilet to my satisfaction. This was my second time having them come for repairs and I was extremely satisfied both times. Prices can be a little high but the work is impeccable and the technicians are always very professional! I would recommend them for any home repair or job that you have. I have actually scheduled a visit for another job as well. Thanks Ken! Great job!ð ð ð"

"Once again Derry Plumbing has met all my expectations for quality work and complete professional service. Mike and Christian just removed a tub unit and replaced with a walk-in shower unit. They were courteous, answered all my questions and kept everything spotlessly clean every day, I've used them for years and will continue to do so and will recommend them to friends!"

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

"It was a pleasure to work with this company! The plumber that came out to do the plumbing on our entire kitchen remodel was always on time, had a great work ethic, always had a smile on, and always asked what we wanted to do about specifics when there were different ways we could do things. (For instance if we wanted our kitchen sink faucet to match our outlet covers, they even asked us if we would be installing a dishwasher and a garbage disposal so that the pipe sizing was correct because the contractor we had hired would show up when he felt like it) The small details they covered are what made it a very pleasant experience. Any time we had questions they were willing to answer. They went above and beyond what other plumbing companies have done for us in the past! We are recommending them to friends and family, and anyone else who needs any plumbing work done! We are about to book them to do our bathroom remodel as well!"

"On all of the replacements or repairs there was a time period of 1 -3 weeks for the repairman. They were all professional . You have to read the contract , I missed the electric part and had to pay for it myself so read your warranty ."

FAQs for sewer main install, replace or repair projects in Dover, NH

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.
