Connecticut does not require a septic inspection to sell a house, but a failing system can cost tens of thousands of dollars to replace. A camera inspection before closing tells you the condition of the tank, pipes and field. Drainworks Level 1 inspections start from $450 with a written report.
Why it matters
A septic system is the most expensive part of a house that nobody can see. A new leach field in Connecticut can cost more than $16,000, and a buyer who skips the inspection inherits whatever is buried in the yard.
What the inspection covers
- Opening the tank to check the baffles, walls and liquid level
- An underground camera through the lines to find cracks, roots and blockages
- A visual check of the interior plumbing that drains to the system
- Up to 2 feet of hand digging to reach components
- A written report with the condition and recommendations
Deeper systems may need our Level 2 inspection, which adds machine excavation and a flow and dye test when needed.
When to book it
Book in the first days of your inspection window. Inspections need dry access to the lids, and spring and fall fill up fast. Pumping on the same visit lets us see the whole tank and saves 10% on both.
If the inspection finds a problem
You get a written price for the repair, which you can use in negotiations. Common fixes like an outlet baffle (from $850) or a distribution box (from $750) are far cheaper than a new field, and the report tells you which one you are facing.
