Septic Inspection in Duncan
Point-of-sale and maintenance septic inspections with the written report buyers and lenders need.
The short answer
A septic inspection in the Cowichan Valley typically costs $300 to $700 and is standard when buying or selling a rural home. Duncan Septic Systems inspects the tank, drainfield, and flow across Duncan, Shawnigan Lake, and Mill Bay and provides the written report that buyers, sellers, lenders, and insurers ask for.
Most Cowichan Valley septic inspections run $300 to $700 depending on system type and access.
What a septic inspection covers
A full inspection checks the tank for cracks, sludge and scum levels, and sound baffles; the drainfield for saturation and surfacing; and the flow through the system under water load. On treatment systems, the components and alarms are checked too. The result is a written report on the system's condition and remaining life.
Buying or selling a rural home
Most buyers, lenders, and insurers want a septic inspection as a condition of a rural sale, and for good reason — a failed field discovered afterward can cost the new owner tens of thousands. An inspection protects buyers from surprises and gives sellers a clean, documented system to point to.
Maintenance inspections
Owners also book inspections periodically to catch small problems early and confirm a treatment system is performing to its maintenance plan, which the Sewerage System Regulation requires for Type 2 and 3 systems.
What a septic inspection includes
- 1
Tank & components — The tank, baffles, and any treatment components and alarms are opened and checked.
- 2
Field & flow — The drainfield is checked for surfacing and saturation, and the system is run under water load.
- 3
Written report — A written report documents condition, any concerns, and what the buyer, seller, or owner should plan for.
Local conditions
Many Cowichan Valley systems date to the 1970s and 80s, so on an older Cobble Hill, Mill Bay, or Glenora property an inspection often finds a drainfield near the end of its life — exactly what a buyer needs to know before closing, and what the tight local soils tend to shorten.
In practice
- Situation
- A buyer was days from closing on an older Mill Bay acreage with an unknown septic system.
- Complication
- There were no records of the system's age, type, or last service, and the lender required confirmation it worked.
- Resolution
- The inspection located and opened the tank, ran the system under load, and documented a functional but aging field, giving the buyer a clear picture and a maintenance timeline before closing.
