Customers say: Quick response

"Overall I thought this project went pretty well.  Cliff Hott (owner) and Kevin (solid worker) quickly diagnosed the problem and told me exactly what they were going to do.   These to guys know what they are doing.  It was amazing watching Kevin...this guy did not slow down as he moved a thousand miles per hour.  I got tired just watching how fast he moved.  They showed up exactly when they said they would to do the repair.  The repair took about 2 hours to complete and then I had to wait an extra day for Loudoun County inspector to come out and sign off on the repair once it was completed.  This delay was NOT the fault of Loudoun Septic.  I take pretty good care of my lawn so I was concerned about them digging the trench and tearing up the back yard.  Cliff and Kevin did am excellent job.  Cliff went the extra mile to dig up solid rectangles of good grass and place them to the side so that they could be place back on trench once it was filled back in.  At the very end of the project, Kevin went above and beyond to make sure he replaced the sod back to the best of his ability.  I am pretty sure many of other of contractors would have just replaced the trench with dirt and not cared about the grass.  For this effort they get an A+.  Another item to note was the Cliff quickly pointed out to me that I had a cheap brand filter in my main septic tank.  He replaced it with a commercial grade heavy duty filter.  He and Kevin gave me a crash course on how to clean the filter and even rigged up a long handle for me to grab it out of the tank so that I would not have to reach way down in the tank to retrieve the filter.  The cost of the new filter and re-cutting of the "T" pipe was included in the total cost.  Laurie who is the office manager for Loudoun Septic was very friendly and was always available when I called to ask questions.

"Great Falls Septic pumped out our septic tank and they did a great job! Kurt was the service technician that came out and he was so polite and professional and called me before he headed our way and arrived right on time. He even took photos of where the tank head was located as we could not remember, and texted them to me. He gave us advice on things to do to help keep build up from occurring which I really appreciated. We had another company pump out our tank the previous time and they were terrible. Will be using Great Falls next time."

"Rick Aits not only answered my initial call at night; showed up the next morning before 8am and diagnosed my issues. My pumping station pump and parts were over 26 years old so Rick replaced everything including pump, check valve, float controls, wiring outside box, wiring conduit and other miscellaneous parts the day after I was able to get both tanks pumped out. I couldn't be more satisfied with a 40 year pro with helper (20 years himself). I knew immediately that Rick knew this system inside and out and he even visually inspected my septic field and researched it at the county records. And for all that parts, materials and expertise his price was super reasonable. Thanks Rick and Mike!"

"These guys do such great, quality work! They were here in the fall, then Charles was here in March to do the annual A/C tune up on both systems. The 14 year old A/C unit is as pristine as the 2 year old unit! No other company has been so meticulous. Charles also thoroughly explained everything to me when he was done. I highly recommend Snell HVAC."

"Owen and Adam arrived within the agreed time frame. They explained what needs to be done before having me signed the agreement. After cutting a portion of the ceiling it was found that the toilet above is leaking—video tape of the leak was shown to me. They then explained what needs to be done to fix the leak—I.e., the commode will need to be taken out, replace the wax and re-seal the toilet. The work was clean and efficient. Owen also gladly took out the bidet that I requested to be taken out and even replace the waterline with a new one. I was also glad that they gave me a senior discount when I presented my AARP card."

"Wow what the best experience I have had with a plumbing company ever. I needed some work done to my well and pump so I called redline. They responded within a quickly manner and were professional. I was there when they came to look at it and when they had to come to the work they came back and were very respectful and hard workers. Everything was done in a timely manner and trustworthy employees. I had to leave and left with them there and I felt that they were good and people I could trust in my house. I can’t thank you all enough. I’m very happy with the work and I appreciate it. I will call again when I need something done. If you need anything done plumbing these are your people to call!! Amazing thank you!!"

Septic Tanks FAQs, answered by experts

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

If you notice a septic smell in the house, you can either call a septic system repair company or a plumber. These professionals have the proper licenses and equipment to investigate the pipes and septic tank while keeping your family safe from sewage gas exposure and raw sewage leaks. They will be able to find the problem as soon as possible and get it fixed so that your home can get back to smelling fresh again.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.
