We are a small family own business. Our services include Septic tank cleaning, repairs and installation and grease trap, cleaning, maintenance and small repairs.

"I got a call from R & E Chief Septic llc after contacting Angi’s List, they asked if I knew the location of the tank and I said yes but it was buried, the woman on the line said they would get the drawings from the county, that same day I got a call from Juan one of the employees and he said he was going to stop buy and mark the location, I was not home but when I got home I could see white flags in the yard. They also recommended installing an above ground cover for the next pump out. I got 2 more estimates and they were all higher and neither company offered to come out and mark the tank. We went with R & E Chief because of the great up front customer service. Need to give a shout out to Juan, Fredy and Paco they did an excellent job. And also the woman who answered the phone. So if you need septic work done, put this company at the top of your list. Ron Welch"

ADDITIONAL CONTACT-HEATHER ADDITIONAL SERVICE AREA- .LAUREL. BOWIE FAMILY OWNED & OPERATED.

"Two-person crew arrived on time Tuesday, June 28. Attempted to clear the obstruction for 15 minutes, but they failed. Crew said they would contact my home warranty company to see if my coverage allowed a replacement. Crew said they'd get back to me in 3-4 hours. Didn't happen. Tuesday afternoon and evening, no call. Wednesday, no call. Thursday, no call. Friday, I left a message in the early morning -- no return call. I called again Friday afternoon at 3:30 p.m. Dispatcher said all technicians were unavailable until NEXT Tuesday (July 5). One week with the problem unresolved is not optimal."

FAQs for septic system installation and replacement projects in Gaithersburg, MD

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.
