"Within a few hours of submitting my search in Angie's List for a company to empty my septic tank, R&E Chief Septic called to schedule the appointment and provide me with the cost. I was surprised at the quick response and immediately set up an appointment. They were on time and quickly went to work. I will definitely use them from now on!"

"The plumber was scheduled to come on 4/23 between 1:00 and 3:00p.m. At 1:00p.m. I got a call saying that the plumber would not be able to come until 4/24 as he was delayed at a previous call. He arrived promptly at 9:00a.m. the next morning. One toilet would not flush properly. He repaired that toilet. The other toilet ran on occasion. He replaced the fill valve. On occasion it still runs."

"Patrick was able to correct all of my problems.  He was quick, provided excellent work, explained to me what he was doing and showed me what he discovered.  Once he found the fracture in the toilet, he was able to order and install the new toilet the next day.  He gave me a fair price on the toilet and labor and even replaced some of the connecting plumbing.  I am more than happy with his work and would recommend his service to anyone needing plumbing work.  He recommended eventually replacing my other two toilets and recommended which to replace first.  I appreciate his work, professionalism and efficiency.  I will definitely use him for the replacements and any other plumbing needs that I have.

"We were having problems with our septic. 1 st we had the tank pumped. Continued to have problems with backing up. Zack and his helper came out and snaked the clean out pipe. Worked for a couple weeks backed up again. Bryan and his helper came out and snaked the pipe again and ran the camera in the pipe which showed tree roots clogging up the pipe. He then ran a root cutting tool in the pipe. As Bryan was doing all of this he explained everything he was doing and why. I was very impressed with his knowledge. He was excellent. He advised we need a crew to dig up the pipe to the tank. Jay and Cody came out and dug up the pipe and inlet access and found clog mixed with tree roots. They cleaned everything up and all is working. Thank all of you guys for your help. I would recommend all them !"

"The service person arrived on time assessed that my water heater (original to the house) should be replaced and help find one that would service the whole house and family going forward. The installation was quick and professional. The service person walked us through diy tips to keep the unit going for years to come. A+ Service."

"Glenn was quick to respond. I was lucky that he was available on the day I called him. He called me for heads-up on his way that he could not arrive on time, which was good to me as I could do something else until the rescheduled time. The requested work was a simple one, so that a big plumbing company on Angie’s list didn’t even respond to my request:( It was nice that Glenn took care it."

Septic Tanks FAQs, answered by experts

Before starting septic tank service in Gaithersburg, confirm permit requirements and review any neighborhood restrictions. Arrange for utility line marking to prevent accidental damage. Check your property’s soil type and drainage, especially if you have mature landscaping or tight access. Gather past septic inspection reports and system diagrams, and plan work for drier months to minimize weather-related delays.

Helpful?

In Gaithersburg, you’ll find septic contractors specializing in pumping, septic inspection, and system repairs. Some focus on installing new tanks or alternative systems for properties with high water tables. Others handle drain field restoration or emergency septic repairs. Environmental consultants are also available to address unique soil or groundwater challenges common in the area.

Helpful?

In Gaithersburg, septic tank service can impact your well water, sump pump, and landscaping, especially if your property has clay-rich soil or mature trees. Heavy equipment may disturb underground utility lines or cause foundation shifts in older homes. Before starting, review your property layout and consider how septic pumping or repairs might influence drainage patterns and nearby water management systems.

Helpful?

In Gaithersburg, persistent soggy patches, foul odors near the drain field, or lush grass over the septic area often signal past septic tank service issues. Slow drains, gurgling toilets, or sewage backups—especially after heavy rain—are warning signs. If you lack septic inspection records or notice work was done without permits, it’s wise to schedule a professional evaluation.

Helpful?

In Gaithersburg, septic pumping or routine septic inspection typically takes 2-4 hours, while minor repairs may require a full day. Larger projects, such as tank replacement or new drain field installation, can extend from several days to a few weeks, depending on weather and soil conditions. Emergency septic services are available, but permanent repairs still follow standard timelines.
