"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."

"literally the worst. we decided to go with this company, pay a little more, to ensure we would be provided a seamless installation of our new HVAC system and it has been nothing but issues for the past 2 weeks. we’ve had a total of 5 technicians come out on 3 separate occasions, only to leave our house with 3 separate issues that are still not all resolved. the communication has essentially bee nonexistent. i still havent received a call for follow up on the issues we experienced last Wednesday. Do yourself a favor and go with another more reliable, trustworthy company that will listen to their customers and put their customers first."

FAQs for septic system installation and replacement projects in Allentown, 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.
