"Tim was excellent to work with. He was quick to respond and quote. Tim handled all the details, coordinating with the Plumbers, Designers, and Permits. While installing the Septic system, he was also hired to do some grading of the property and install a foundation for a large addition. His quotes were fair, he stayed on budget, and his subcontractors were excellent. Most importantly he answered all of my concerns and questions throughout the job. I will definitely recommend his company. "

"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."
