"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

"Excellent. I called Ferris Plumbing on a Thursday afternoon and left a message. Matt returned my call the next morning. After I explained the problem, Matt said he would try to get to me that day (Friday), but he may not be able to. Meanwhile, he suggested not using that toilet. He called later that day and said he couldn't make it, but would be able to on Monday. He called me on Monday morning to confirm that he would be coming and gave me a estimated time of arrival. Matt wasn't able to come himself, but two of his plumbers arrived mid-morning. I explain all of this because Matt's communication was OUTSTANDING. I always knew the status and I knew he would be arriving as soon as he could. His two plumbers were also excellent and efficient. They replaced the toilet flange and gasket, and remounted the toilet without needing to disturb the downstairs ceiling. I should mention that the toilet is the original installation of 48 years ago. The original gasket was completely disintegrated to the point that only few small fragments of it were left. They were also very careful to protect the carpet just outside the bathroom by placing a drop cloth to protect it. Their service and work was EXCELLENT. We are considering remodeling that bathroom and Ferris Plumbing will certainly be our first choice to do the work. I highly recommend (Matt) Ferris Plumbing."

We will come out and meet with you to discuss your ideas. Once we do this a detailed estimate will be emailed to you. A full contract will be prepared with a payment plan once you decide to go with DCR Building & Remodeling.

"The project went very well and we were extremely pleased with the quality of work done by DCR Building and Remodeling. Dave was always available to answer our questions and the project was done on time and budget. The installation of the handicapped accessible bathroom was especially challenging. There were 5 doorways including the bathroom entering to the same hall and everyone of them had a different height floor. Dave and his crew did a fantastic job of leveling all the floors so the Wedi waterproof flooring in the bathroom worked properly. It is obvious from their work that they are highly skilled and very detailed oriented. I would hire DCR again without hesitation."

Septic Tanks questions, answered by experts

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.

Your garbage disposal will only affect the health of your septic tank if you’re using it too frequently, or filling it with organic waste that doesn’t fully break down. If the tank fills up with too many solids, the bacteria won’t have enough time to consume it before more is added, which can lead to an overflow in the drain field. Your tank will need to be pumped more frequently with excessive or improper garbage disposal use.

Wells vary widely when it comes to lifespan, and there isn’t a way to exactly predict how long a well may last. Some wells can last well beyond 100 years, but they more commonly last between 25 and 50 years. Performing regular maintenance, such as replacing worn valves, can help prolong the life of your well.

If your septic tank is still within its expected lifespan and you need to relocate it on your property, it's possible to do so. However, because the task is so labor-intensive and costly, most homeowners simply choose to abandon the old tank if possible and install a new system in the new location. In either case, hiring a professional installation company will be necessary for the job. 

With regular servicing, a well pump usually lasts between eight and 15 years. Variables include level of usage, frequency of servicing, and pump quality. You may also be able to hire a local well pump repair service to fix your pump rather than replace it. 

However, often the cost to fix significant problems is as much as or greater than replacing the damaged pump with a new one.
