See what Clients are Saying About Us

u0022Our parking lot was flooding and eroding over the bank into a brook, with pressure from the town to remedy the situation, our communities landscaper attempted to stabilize the embankment but was unable to identify the cause. NESS arrived with specialized equipment and knowledgeable staff to clean the storm sewer, pinpoint a collapsed section of pipe and repair it quickly and affordably. We now contract with them annually to inspect, evaluate and clean our entire stormwater system and keep us up to date with the new DEEP regulations.u0022

Kathy L; Self-managed condominium board member

u0022All of our other quotes included digging up and replacing the stormwater conveyance piping that lead from one of the buildings roof gutter system to a storm sewer across the finished lawn which was costly and disruptive, NESS suggested jetting and vacuuming the underground piping to remove almost 40 years of deferred maintenance and in just a few hours had the system cleaned and functioning properly; they ran a camera and also performed a dye test to verify the system was completely clear. We are currently scheduling an annual cleaning of all of our buildings, Thank you NESS!u0022

Michael; Property Manager

u0022We just completed a year-long project with NESS building a private road and large detention pond for a four lot subdivision. A complicated project with difficult topography and specific engineering. Their in depth knowledge and decades of excavating experience made them a good choice for me as we navigated challenges together. Good communication, regular explanations kept me comfortable and confident through the duration of the project. Peace of mind goes a long way in the construction business; NESS will be my first call on all of my upcoming development projects.u0022

A properly maintained septic system can last 20–40 years or more. The lifespan depends on factors such as soil conditions, system design, maintenance, water usage, and the quality of the original installation.
