We are general mechanical electrical contractors specializing in residential and commercial applications your one stop shop for all your needs

"We hired this contractor almost a year ago to do various projects. The work was supposed to be finished in 10 days according to the contract. We are here almost a year later and there is still work that is unfinished. I paid Martin before all of the work was completed, and I can’t get ahold of him to finish the work now. The pipe still hasn’t been cut, and there is still a huge piece of concrete in our side yard. I’m not sure what to do now."

Ask about an Angie's List discount. Additional DBAs - Always Dry Basement Waterproofing, Media Waterproofing.

"Coulter Systems installed a french style drainage system in the basement/part of the garage of the house. The paperwork indicates a transferable lifetime warranty. After we bought the house in 2018 we had continued flooding in the basement where the drain system was installed (muddy water). They came out to the house to try to clean it and informed us to reach out if it happened again. Every few months we have called and left messages but nobody returns our call. We have sent emails since 2018, most of which have gone unanswered. The basement continues to flood where the drainage system is with thick, muddy water but we have been unsuccessful in having anyone come out to look at or rectify this issue. The only part of the basement that floods in excess is where this drainage system has been installed. We want the company to come and repair/redo the faulty drain system to prevent our basement from continued flooding."

FAQs for septic system installation and replacement projects in Williamstown, NJ

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
