Why Specialized Inspections Matter
A general home inspection generally does not provide complete well and septic evaluation.
Frequently Asked Questions
Does clear water mean the well is safe?
No. Water quality requires appropriate testing.
Does a recently pumped septic tank mean the system is healthy?
No. Pumping does not evaluate every component or long-term function.
Can I add bedrooms to a septic property?
System capacity and local approvals may restrict expansion.
Well and septic issues can affect daily use, future construction, health and repair costs.
