"I had a new HVAC system installed by ( remove company name) which is now Heritage. I called Heritage about a service plan. They said a service needs to be done. I said your company just changed my filter and cleaned the system (literally a week ago). They said only the tech can sign you up so we need to do another service. I said I did not need another service. They insisted. I talked to Chris, one of the service managers and he would not budge. I called again and explained situation. Never heard back. Will not be doing business with a company that does not return phone calls when a customer is begging them to take money for a service plan. Such a poorly run company. So done with them. "

Grady Consulting LLC is a family owned and operated professional Civil Engineering Company serving Massachusetts since 1998.

"I was looking for a surveyor to do some work on our property. As a long time member I've used Angie's list in the past, but haven't had occasion to do so in quite some time. I looked at the companies that were available in our area and considered Grady Consulting. I was somewhat surprised to see that they only had one, brief review. I made the decision to call after viewing their web site. I first spoke with Marianne at Grady Consulting in late June. I mentioned to her that I had found them on Angie's list and was somewhat concerned that they only had one review. She told me that they were not an Angie's list member. Since everyone I had hired was a member, I appreciated that she informed me that they were not. Since we have never had a survey done of our property, I was unfamiliar with how things worked but told her that we wanted to have our property surveyed and the lines staked. We also wanted a plan showing the elevations and location of the house on our lot. I also mentioned that we wanted this information so that we could have an architect draw up plans for a possible, future addition. Marianne was my first contact and thus my first impression of the company came from her. I found her to be a good listener and very knowledgeable. She both asked and answered my questions and responded to all my concerns. She also asked me about my future plans. She was able to pull up our lot on her computer and to let me know that our property had some wetlands in one corner and said that they would also be able to have their botanist walk the property and mark any necessary areas of concern. She repeated back all that I told her I would like to have done and said she would work up a proposal for us. Then, after reviewing the proposal we could decide on what and how much we wanted to do at this time. After speaking with her, I felt that they were very professional in their approach and was comfortable in taking the next step. We received an email that showed our property on a map and were able to see the small area of wetlands that were mentioned. Also, a very comprehensive proposal that listed the scope of services, the estimated fee schedule, the payment schedule and a rate schedule. Out of the 13 listed services we decided to do the first 4. We decided to wait until the late fall, when they would be less busy, to have the work done. In mid November I called and gave the required retainer and said I would bring the signed proposal to their office because I wanted to show them some old plans we had showing a few changes that had been made over the years to bordering properties. I met with Mr Grady who was very polite and professional. He listened to my concerns, answered my questions and then made copies of the old plans. The next day the botanist came and flagged the wetland areas. He spoke with my husband who told me that he was very knowledgable and personable. Two days later two men came and spent a few hours working and then marked the corners of the property with stakes. The rest of the work on the property took place after the Holidays. My husband did have occasion to speak with the surveyor and mentioned that he was very professional and quite jovial considering the extreme, cold weather on that day. We received the progress invoice for the completed work and it was structured so that you could easily see what was done, who did it, how much time it took, what the rate was and how much we were billed for each service provided. The estimated fee given for this job was somewhat higher than the end cost. An envelope containing two copies of the existing conditions plan arrived a week or so later. Since we received a list of 13 services and decided only to do 4, we now have the information for future work we might decide to do."

FAQs for well pump repair or service projects in Merrimack, NH

A standard well inspection begins with a visual inspection of the pump, casing, storage tank, and wiring, followed by flow rate tests and laboratory-based water sampling. The goal is to confirm that every part meets safety standards and to identify any necessary repairs before they become expensive. An inspector will also test your water quality for substances such as volatile organic compounds and any local containment concerns.

Book a licensed, insured well specialist for your inspection. Many well‑pump contractors also hold inspection credentials. They’ll bring the right tools to assess the pump, wiring, and water quality, and provide you with a clear report on any necessary fixes. Before you hire, confirm their license, insurance, and recent customer reviews.

Plan on a full well inspection every year. You’ll also want one any time the cap comes off, after septic repairs, or if flooding occurs. Annual tests look for total and fecal coliform; every two years, the lab should screen for metals and nitrates, and every five years for VOCs and pesticides. If you’re buying a home with a private well, it’s essential to schedule a pre-purchase inspection.

With routine care, most wells supply clean water for up to 40 years. Lifespan depends on the type and how well you protect it. To help it reach the maximum lifespan, keep hazardous products far from the casing, ensure the cap stays sealed, schedule yearly inspections, and address problems as soon as they appear. Good habits keep the system healthy and the water safe.

The average cost of well repairs ranges from $100 to $2,800. Your final bill depends on which part—pump, pressure tank, casing, or piping—needs attention and the level of complexity involved in the repair. A thorough inspection identifies the problem, allowing you to budget accurately and avoid paying for unnecessary parts or services.
