Hello, I am writing…read morethis message to share my wonderful experience with a recent service performed at my home. I had an excellent experience with GAP Mountain Drilling, LLC, a small, family-owned company founded by Garth Dubois and headquartered in Franklin, New Hampshire. They came highly recommended by a trusted family friend, Andy Davis, and I am truly grateful for that recommendation. I first contacted GAP Mountain Drilling at 8:30 a.m. and left a message. To my surprise, I received a call back within just 10 minutes, at 8:40 a.m., from Ms. Yasmine, who handles and filters all new potential jobs. From the very beginning, she was incredibly kind, professional, and attentive. She listened carefully to my situation, responded promptly, and immediately made me feel confident that I was in good hands. Within just a few hours of that initial call, Ms. Yasmine provided clear and detailed information that allowed us to move forward with repairing my well pump. She was completely transparent and honest about the costs and walked me through the entire job process step by step, which I truly appreciated. Once we agreed to proceed, she followed up promptly with confirmed ETA arrival times for the technicians, keeping communication clear and consistent throughout. The technicians David (Senior) and his son Zak (Junior) arrived right on time. This father-and-son team immediately assessed the situation, quickly troubleshooting and confirming that my well pump needed to be replaced. Both were extremely professional, knowledgeable, and reassuring. They put me at ease right away and assured me that everything would be taken care of. In just two and a half hours, they successfully replaced my well pump. Their efficiency, expertise, and teamwork were truly impressive. They provided exceptional value for the level of service delivered, treated my property with great respect, and left the work area clean, organized, and spotless once the job was complete. If I had to rate GAP Mountain Drilling, LLC from start to finish on a scale of 1 to 5, I would confidently give them a 5+. From the initial phone call to the completion of the work, this was truly one of the best service experiences I have ever had. Their professionalism, honesty, responsiveness, and quality of workmanship reflect the old-fashioned way of doing business where customer care and doing the job right truly matter. I highly recommend GAP Mountain Drilling to all New Hampshire Seacoast families. When it comes to wells, pumps, or geothermal systems, they are without question the clear and trusted choice.

Not good business.

I'm not a water expert. I can, however, tell when water isn't right (smell, color, pressure) and I…read morecan read lab reports. We bought a house and, after local recommendations, turned to Gilford Well for help. Amazing job. They were on time, way under budget and fixed everything! Water clarity (Iron)- perfect; Smell (sulfur)- perfect, Pressure(low)- perfect, Contaminants (Bacteria)- perfect, Well head (below ground) -fixed. Gilford and their team of Dave, & Chris and others did more than we planned, and only what we needed. The results were far better than expectations- which is what happens when you hire experts!

We had only lived in our new home for 24 hours when the dug well dried up. (Seller misrepresented…read morethe situation) Contoocook Well responded immediately and drilled an artesian well for us. Now, 47 years later, the original pump gave out. Contoocook Well responded immediately again, sending a competent, courteous technician. The troubleshooting and replacement were done in one afternoon, and instructions as to how to manage shock treatment of the well after opening the well were thorough. We're very grateful this excellent water service company is so close by, and so capable of responding. (And the price was reasonable.)

I called Contoocook well first thing Monday morning and spoke with Katelyn. She was quick to get back to me within and hour to tell me that a crew could be at our house sometime later that day. Mark and his brother had the pump replaced and flowing water again by noon time. Now that is prompt and professional service.

My residential well was originally drilled to approximately 425 feet and had been functioning…read morenormally. Over the course of several months in 2025 and early 2026, I repeatedly contacted Capital Well requesting service to inspect the well system, measure water levels, and repair a well cap. My goal in making these requests was to proactively prevent system problems. Despite numerous attempts to schedule service, the company did not respond to my requests. Eventually, my well system failed when the well pipe froze. When I contacted Capital Well again, they indicated that a "system glitch" had prevented them from receiving my earlier service requests. They subsequently came to the property to replace the well pump. During installation of the replacement pump, their technician informed me that a piece of shale likely slipped during the installation process, preventing the pump from being lowered further into the well. As a result, the pump could only be installed at approximately 160 feet, leaving more than 250 feet of the original well depth unusable. This effectively eliminated access to the majority of the well's water column and significantly compromised the reliability of my household water supply. Even the owner of the company, publicly stated that a well pump at my depth has had this year in New Hampshire. They are trying to claim "act of God" language. When I raised concerns about this outcome, the company informed me that they would not accept responsibility for the obstruction and advised me to simply continue using water normally. No remediation plan was offered. The situation has created significant financial hardship. I was required to take out a second mortgage to cover the cost of the pump replacement and related work already performed. they breached their contract multiple times and there are ethical standards that have been broken. They wanted to charge me $13,000 to repair what they broke taking zero responsibility for their workmanship. I have requested documentation multiple times with no response. I have requested formal mediation multiple times with no response. I have file a claim insurance with no response. I had offered to speak to the president directly to work through this, but became aggressive and rude. Once I filed a complaint. This company is very much unprofessional And overpriced.
