"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"I am a big fan of Heritage. We needed to replace our broken furnace and I got quotes from five different HVAC companies, all of which had many 5-star reviews. Heritage was the best, by far, for a few reasons: Dexter, the HVAC project manager from Heritage, was professional and patient. He answered all of my questions, applied no sales pressure, helped me customize the job to my budget and needs, and even brought us space heaters to keep the house warm since we had no heat in winter. Heritage was one of only two companies to actually take detailed measurements of my home before recommending a furnace size and submitting an estimate. Three of the companies just eye-balled it and recommended furnaces that were twice the size of what Heritage recommended. Some of them told me I had to replace my entire heating and cooling system or I would have major problems (which Dexter debunked). If an HVAC project manager does not bother to measure your house before recommending a furnace size, you should be concerned. Dexter helped me every step of the way with the HEAT loan and furnace rebate process. Dexter worked around my busy work schedule and communicated in person, phone, email, and text, depending on what was best for my workday. After the furnace was installed, the house got uncomfortably dry and we realized we needed to add a whole-house humidifier (which Dexter had recommended originally). Heritage was able to come out the morning after we called and put in a humidifier and the house was comfortable within a day. The Heritage install and service guys (Fran, Bob) were professional, patient, and courteous from start to finish. The installation site was clean and well-labeled. They checked in with me and explained important items along the way. The Heritage office staff are always reachable and helpful with any scheduling, billing, or follow-up questions. The only drawback is they are definitely a premium brand and charge on the higher end for their work. They quoted higher than any of the other four companies. That said, I was able to negotiate the price and I was happy to pay a little extra for a job well done, a strong warranty, and professional service. Honestly, Heritage won me over and I will only use them in the future for my HVAC needs. They were transparent and professional and I never felt like I was getting hustled (unlike a few other big-name brands). Now I recommend Heritage to everyone I know."

"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!"

"A friend of mine referred me to Viper Drain Cleaning. I couldn’t get the tub to drain properly so after trying a few remedies I called them to help me out. The guy who showed up was friendly and professional. He wore plastic wraps over his boots and thoroughly cleaned the tub afterwords. After checking the whole system he showed me what looked like a leaking pipe in the basement. He kept me updated, showed me photos of the work and made sure I approved before proceeding. I would certainly recommend this company to others having plumbing or draining problems."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"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!"

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