"John is very responsive and professional when it comes to dealing with the customer. He does what he says he will do. His team was on time to do the diagnose and assess the problem. The septic pump install went without a hitch. He even let me borrow a loaner pump so we can live normally while the new pump was being ordered,"

"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."

FAQs for septic system repair projects in Ashburn, 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.
