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"

Family owned & operated. Financing available. Credit cards. All work done by experienced professionals to ensure consistent high quality. Award winning company at your service.

"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

FAQs for septic system installation and replacement projects in Fairfax, VA

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.
