Septic System Installation & Repair FAQ for St. Louis Homeowners

How often should St. Louis homeowners get septic system installation & repair?
Given St. Louis's severe tornado and hail risk in spring and fall along i-44 and i-70 corridors, most homeowners benefit from septic system installation & repair at least once a year. Ice storm branch and gutter damage (Dec–Feb) often makes spring or fall the optimal time to schedule service.
What home types in St. Louis most need septic system installation & repair?
Red brick bungalows and two-stories throughout St. Louis County and Victorian homes in Lafayette Square and Compton Heights are the most common home types in St. Louis and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How long does a septic system last?
A properly designed and maintained septic system lasts 25–30 years. Drain fields can last 25–50 years. Premature failure is usually caused by improper use (flushing non-biodegradables, using garbage disposals heavily) or lack of pumping.
How much does a new septic system cost?
A conventional gravity system typically costs $5,000–$15,000. Alternative systems (mound, aerobic, drip irrigation) cost $15,000–$30,000 or more due to site constraints and added complexity.
What causes a drain field to fail?
The most common causes: solids overflow from an unpumped tank clog the drain field, hydraulic overload from too much water, root intrusion, and physical damage. Failed drain fields usually cannot be rehabilitated and must be replaced.
Can I add a bathroom or bedroom to a house with a septic system?
Additions may require a system upgrade if the existing system isn't sized for the additional load. A septic evaluation is typically required for permits involving additions.
