Why choose a pre-purchase septic inspection?

If you are buying or selling a home or cottage, a pre-purchase septic inspection is an effective way to limit your risk before the transaction is completed.

The reason is simple: an inspection makes it easy to spot a clogged, damaged, or faulty septic system that may create unexpected expenses for the new property owner.

As part of most real estate deals, the buyer hires a building inspector to look for any unpleasant surprises. Inspections include visual assessments of the building structure, plumbing, electrical, insulation, ventilation, and more.

The problem is that conventional inspection services do not take an in-depth look at a property’s wastewater treatment system.

Without a pre-purchase septic inspection, it is difficult for a buyer to determine which technologies are installed, how the system has been operated, and how frequently it has been maintained. There is also no way of knowing if the septic drain field is in good condition, if wastewater is being treated effectively, or if the system protects the environment.

That is why we strongly recommend that you invest in the services of an inspector who specializes in wastewater treatment.

It is their job to protect your peace of mind!
