David O'Neil Construction

I live on Granite Lake, and learned that my septic pump had stopped working. I called David O'Neil Construction and actually spoke to a person immediately, who put me in contact with Matt - Matt came out that afternoon, assessed the problem, and was back at the house in 2 days to install a new pump. Given my situation, timing was of the essence, and DOC came through with flying colors. I much appreciated their speed and quality of work, and they are now my "go to" for any future issues that they can handle.

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!!

It is such an amazing company for any and all your septic issues. They are also responsible for the annual christmas tree lighting in the heart of Harrisville. They are who I will always call for all my septic needs, and they should be your go-to as well

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.

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.
