Drain Field Services in Southern Maine
Protect Your Property with Expert Drain Field Repair & Replacement
Your drain field (also called a leach field) is the final stage of your septic system, responsible for filtering and dispersing treated wastewater into the soil. In Maine's climate, freeze-thaw cycles, heavy rainfall, and soil conditions can take a toll on drain fields, leading to failure if not properly maintained or replaced.
At Septic Advisor, we provide comprehensive drain field services throughout Southern Maine — from inspections and repairs to full drain field replacements — ensuring your septic system meets Maine DEP standards and functions efficiently year-round.
Service Area
Portland, Westbrook, South Portland, Cumberland County, and the greater Cumberland County area (will travel to other locations upon request).
Signs You May Need a Drain Field Replacement
Standing Water or Soggy Ground Over the Drain Field — Saturated soil above the leach field is one of the most common signs of drain field failure.
Foul Odors in the Yard — Persistent sewage smells near the drain field indicate wastewater is not being properly absorbed and filtered.
Slow Drains Throughout the Home — When the drain field can't accept more water, it backs up through the entire plumbing system.
Lush, Green Patches Over the Drain Field — Unusually green or fast-growing grass over the leach field suggests excess nutrients from surfacing wastewater.
Septic System is 20+ Years Old — Maine's soil conditions and freeze-thaw cycles can accelerate drain field deterioration over time.
