"I can’t emphasize enough how complicated this project was, it was far more complicated than moving a couple of boxes and reconnecting them. The previous owner had paved over the top of both boxes making it impossible to service them without tearing up the driveway. Additionally the leach field was on the other side of the driveway which meant all of the header lines had to be ran underneath a driveway and be able to withstand the pressure of being driven over. All of this required several months of prep work and permitting from the county before we got started. The Project was started and took about 3 days to complete. I have to say that Rick and his crew were consummate professionals and absolutely know their trade. This was an expensive but necessary project. I have about 20 years experience in commercial construction and know very well that under a person with less expertise this project would have cost even more and would have been a disaster. It is my humble opinion that for the money you pay and the work that you get there is no better septic repair company in this area. Rick is absolutely the best at his field and is very fastidious with the quality of the work done and the cleanup of the job site afterwards. If you only want to do a repair once and do it right A &A septic repair is who you need to call bar none!"

"I hired this company for an initial inspection of the septic system because their prices were lower than other companies. However, after the issues a failure certificate for the septic system, their charges to make repairs were almost double those of other companies. And they recommended repairs that were not necessary, increasing the price. I brought in two other contractors in the region to offer estimates of what work needed to be done. Both were significantly lower in price and did not pad the bill. I ended up getting the work done by another company and the septic system passed the county's inspection."

"Expected Snell to be one of the higher bids, based on all of the good things I head heard/read. They came back with very competitive pricing for Lennox gas furnace and air conditioning systems which they installed quickly and professionally. Great experience."

"They were remarkable. First, they excavated the minimum needed to repair our drain and install the CIPP liner. They saved our front cement and brick staircase (directly over the main house sewer line). They only removed one section of the sidewalk that was over the main house sewer line. When done, they filled and compacted the dirt, covered the lawn with straw (i.e., ready for me to add seed and to avoid erosion) and replaced the damaged sidewalk section. The workers were polite and respectful of both us and our property. There was truly minimal disruption to the household. We could not flush toilets or run water down the drains for about 3 hours each day they worked on the line. We contracted for repair of the pipe that was on our property. They completed this work in two days. We then added re-lining the pipe under the road to the county connection. The team added people for and worked late on the second day. Job done on day 3. The job took 3 days (as promised)."

"Work performed on a leaking toilet. Arrived when he said he would, provided advice in the event of a similar issue with any other toilets, and let me know the condition of the toilet since it is old and probably installed when the house was built (1977). Very reasonably priced. I plan to use them for any future plumbing requirements/issues."

"Their technician mason Craig was obviously very well trained. He diagnosed the problem within just a few minutes and thoroughly checked the rest of the AC unit components and HVAC system. Clover services was Great about getting someone out to the house late on a Friday afternoon. Mason was good about explaining everything he was going to do and how the AC system worked and he gave me an estimate for a future upgrade of the system as mine is getting older. I would highly recommend this company they are very professional and well trained"

"We bought the whole water system from these guys. The issue has been the water supply because it is a well and it is low pH and acidic. The corrosion was constantly eating through the part of the system where it neutralizes the pH. So everything after the neutralizer was okay because the pH had been neutralized. Prior to that, it was subjected to being corrosive so I was pushing for years, because they were putting sub standard parts in and we were getting mini floods, to put stainless steel in there. It cost a little extra, but this time they came in and put some stainless steel or whatever he could find, because it was less likely to corrode. Even though it is a challenging system, we did spend a lot of money six years ago on this water system, the pump, the units, then on top of that, we have already been through two water heaters because of the corrosiveness. I can't hold all of it against them, but the part where it's getting corroded, they did come out and fix it. We know what the problem is, but they need to find something creative to fix it before there's another flood."

FAQs for septic system repair projects in Alexandria, VA

You should have your septic tank inspected at least once every one to three years. Regular inspections help catch minor issues before they become major problems, ensuring your system operates efficiently and extends its lifespan. You can also have your pro take care of routine septic system maintenance tasks at the same time as your inspection.

A septic tank must be inspected before buying a home to ensure the system is sound and compliant with local regulations. A comprehensive inspection evaluates all critical components and detects hidden faults that could lead to expensive repairs. This detailed review protects your investment by verifying the system’s integrity and reliability.

A septic tank's leach field fails when it encounters system overload and deteriorating conditions. Excess water usage beyond the field’s capacity and environmental stress lead to hydraulic failure. Aging infrastructure and insufficient maintenance further contribute to failure. Distributing water use evenly and scheduling regular maintenance, including enzyme treatments when necessary, preserve the leach field’s integrity.

A septic system lasts between 20 and 30 years. Steel tanks function for 15 to 20 years, concrete tanks operate for 20 to 40 years, and fiberglass or plastic tanks remain durable for 30 to 40 years. Consistent maintenance, including regular pumping and inspections, extends these lifespans by preventing buildup and structural damage, ensuring reliable long-term performance.

A failing septic system presents clear signs such as slow-draining fixtures, foul odors at or around the leach field, and overly green patches of grass. Additional indicators include persistent toilet flushing problems, standing water near the system, and noticeable gurgling noises from pipes. These symptoms reveal blockages, structural damage, or leaks. Immediate professional evaluation is essential to address these issues and prevent extensive repair costs.
