"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."

Hi I am Darryl Ames, Owner of Kacena Site Work Support Services, LLC. I have been doing Site work and septic systems for over 40 years. I used to own KIB Excavators, but due to the economy in 2008, I chose to sell my equipment and work for the guy I sold them to. Recently, I decided to go back out on my own, and see if I can help some people solve their septic and drainage issues. I believe in doing the job right the first time, giving the customer more than they expect, and try to do it at a reasonable price. "It's never wrong to do the right thing"

"Great price and great service!! Definitely would recommend Daryl to anyone looking for a company that communicates and committed!!!!"

FAQs for septic system installation and replacement projects in Exeter, NH

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.
