"We just had David O'Neil Construction install a new septic system for our home. David and Matt were an absolute pleasure to work with. Everything they did was top notch and they paid attention to every small detail. They ended up doing a few extra small things at our request and they did them without issue or extra fees. Look - it's no fun spending hard earned money for a septic system but if you are going to it - these are the people you should be working with! Thank you for going above and beyond!!- John"

"They do good work, do not mess around. Our crews always like it when we are on a job together, the men and equipment show up on time and are prompt. Customers happy with the work and the pricing. Highly recommend. - Bart"

"Pat and I would rate O'Neil Construction 10 on a scale of 1-10 with 10 being excellent. We had our driveway regraded with more drainage along the sides and pipes placed under the driveway where water could be diverted. A good base of gravel was put down with a top layer of SurePac on top . The estimate was well detailed listing exactly what would be done. The estimate was discussed with Pat and I and explained well answering all of our questions. They were prompt in the estimate and when they came to do the job, the two men worked taking very little breaks, operated the equipment very well and were very professional toward us. As they worked, they suggested changes and discussed them with us. They did more than was on the contract. The men estimated that it would take about three days and they were done in a little over three. Based upon our experience, we recommend O'Neil Construction with no reservations. -Pat and Richard"

"These guys are top notch! Receptive, professional, timely and very personable they provided piece of mind and a timeline for doing the repairs. Their services will certainly be used when the time comes for my new septic field! Thank you!- Alicia"

"There is a reason these guys have a 5.0 rating! We just had our culvert replaced last year in Richmond by O’Neil excavation. With the recent heavy rain and flash floods our culvert held strong even with rain rushing up and over the culvert and washing out our entire road. In 20 years the town has never seen that much rain on our road and even mentioned how well the culvert was made to handle that much water. It took the town 4 days to repair the road but our culvert held strong. All thanks to the hard work from O’Neil excavation! I can’t thank you guys enough!- Andrew"

"What a great company to do business with! Everyone I spoke to, owner, staff or crew were friendly, helpful and pleasant. Right from the start they were very upfront about the extent of what needed to be done for our septic system. No sugar coating things and quoting a lower price, only to have to raise it later! Their honesty and integrity was very appreciated. They did the work with professionalism and quality. Buying a septic system is never fun, but if you have to do it, O'Neil Construction will do it right the first time. - Sue"

"David and his crew were very helpful in updating our forty+ year old system. Our need was urgent and they got a new system installed quickly. We expect it to last a long time. Thanks for a job well done! - Priscilla"

“Wow 2/13/17 Thank you, Thank you for a GREAT job opening my driveway to be very proactive against future storms. – Marianne (repeat plow customer)”

"Matthew and Jason came out to inspect our septic system. They were the most kind and respectful young men I have worked with in a very long time. - Brenda"

"David & Matthew, Thank you for your expertise & assistance with our septic inspection. We were disappointed to learn that the sellers of our home did not get their act together in time to use you for the system replacement. We would have preferred for you to do that work. I'm sure we will see you around town! Best, Erin & Dan"

"Thank you for your patience and quick response. -Renee & Eric"

"Hi Dave, Looks Great! I'll probably check in with you at some point to review the alarm and frequency of pumping the tank. Thanks again- Mary"

"Two years ago, the septic system at my lakeside home desperately needed to be modernized. David came to evaluate conditions, called in an engineer to design the proper system, and followed up with all required permits and inspections throughout the process. He and his son performed all the site work, including removal of a paved driveway which had delivered excess rainwater and snow melt-off into my basement for years (that project uncovered an additional ancient septic tank!) Matt recommended recycled asphalt for the new driveway surface, which is permeable and friendlier to the environment near water - no basement water problems since! They finished with a seeded spray lawn cover, and were even able to leave part of an old rock retaining wall by my garage to minimize the changed appearance overall. In spite of additional work and complications during the process, my final bill was not much higher than the original estimate. I trust and appreciate the quality of technical knowledge, service and attitude from this family business, including Janelle's office support. I highly recommend this team. - Donna"

"They are almost too good to be true. Honest, fair, and dependable. Don’t waste your time (and money) on other contractors for your septic/leach field needs, or for all of the other services they provide. - Brad"

"Dave and Matt, Thanks to both of you for another year of great service. -Toni" (repeat plow customer)

"We used David O'Neil Construction for several projects and were very pleased with the professional way he did each project, priced fairly and done in a timely fashion. One of the projects that we cannot thank him enough for is his consultation and working on stopping water from coming in our property. He installed the perfect drainage to keep the property from water seeping in from every rainstorm. - Maria"

"David, Thank you for another year of great service. Take care. - Enid" (repeat plow customer)

"David & Matt, You did a great job on the Peanut Row driveway. Thank you- Barbara"

"Long hours for all of you- We appreciate the great job you do. Thank you- Bob"

"David, Thank you for the great job. All good wishes. - John"

"Thanks for all you did. It looks great especially around the barn area. The grass is starting to show over the tank and field. Hope your summer goes well. - Cindy"

"David- Many thanks- the driveway looks terrific and the drainage work has done the job of drying up the area. Please let me know if I need to do anything to advance the work we'd like to do near the pond. Best regards! Lori"

"Thank you so much, David for your work at my house site following the fire. It was inspiring how people like you just stepped right up to help. Best wishes for your family in the New Year. - Mary" (This was from a neighbor in our community for full site work we did when her house bunt down. All work was donated.)

"We used David O'Neil Construction to install a cistern in Chesterfield N.H. . They did a great job with the work which passed inspection the first time on the prep work as well as the installed final inspection. They handled a great deal of the paper work which was needed as well . Janelle the office manager was pleasure to deal with , always willing to help out. They have a good team here. I would use they again without hesitation. You should too. - LCP"

"Dear Dave & Matt, Thank you for all the awesome hard work you've done for us at our place, and a huge thank you for doing us a solid on the price! - Mike & Sharri

"Matthew, We know that some people do not feel the same about their animals as we do, we are heartbroken! It meant a lot to us to bury Syb in the area that she loved to investigate each morning, to smell tracks and scents of any wild life that may have passed through during the night. She gave us so much joy and unconditional love. She continually made us smile from her antics…we miss her very much but her spirit is still with us. We want to thank you for coming Feb 23, 2011. You certainly have excellent skills operating the backhoe. The shovel for all its weight and size may as well have been a “feather” as you expertly placed it very gently where you needed it. Your mom & dad have every reason to be very proud of you. We not only appreciated your skill with the backhoe, but also the care and respect you showed. Thank you Matthew! - Sincerely Bob & Donna"

“Hi Dave! I just wanted to thank you for all that you did on our house. You did a great job and it was a pleasure to work with you and the guys! Thanks! – Dean”

“Dear David & Matt, Many thanks for your great work on our house at 102 Breed Road! Dell and I, and our whole family of cousins and friends appreciate it enormously! Kind regards – Lou”

“Dear David, We are very pleased with the work that you and Matt did on our garage floor, work bench and driveway. Each part of the job was done efficiently and professionally. Thank you for your services and responsiveness to what the “vision” was (even as it changed sometimes). Dad’s Harley is now in the garage, and he is also very pleased. Thanks again. Sincerely, Cameron”

“During the mid-winter of 1997, David O’Neil constructed a 20’ X 120’ storage warehouse for Belletetes Incorporated. He handled the job in a very professional manner and completed the project on a timely basis. I would not hesitate to contract him for future projects as they may surface. I would highly recommend him for carpentry projects because of his quality of craftsmanship and professionalism. – John”

“I recently had an addition constructed onto my home in Harrisville, NH. While selecting a contractor, I became acquainted with David O’Neil Construction. Hind sight is a wonderful thing and I am very happy with my decision to award the contract to David. He produced a very high quality project, on time and one budget. One of the most annoying things about building projects are contractors spreading themselves too thin and not showing up when they’re supposed to. In my experience David accepts only the amount of work that he can handle and goes about it in a diligent way. This coupled with his quality workmanship and fair dealing approach, make him in my opinion a very desirable contractor. I would recommend David O’Neil Construction without reservation. Yours truly- William”
