Selling a home is stressful enough without a surprise popping up in the eleventh hour. Yet for homes with a septic system, it happens more often than you'd think. A cracked pipe, a saturated drain field, or a missing baffle can turn a smooth closing into a renegotiation, a delay, or worse, a terminated contract.

We teamed up with Rebecca Quell, a real estate agent with Keller Williams Platinum Realty, to talk about how septic issues show up during home sales and what sellers can do to stay ahead of them. Her experience on the closing table, combined with our experience in the field, paints a clear picture: septic problems are common, but they are also preventable.

When Septic Issues Actually Surface

According to Rebecca, septic issues tend to show up at a very specific point in the process.

"Septic issues are most commonly discovered during the home inspection period, when the buyer has a separate septic inspection performed," she explained. An appraisal, on the other hand, is focused on value and marketability, not the condition of the system underground. That means a home can be appraised without anyone catching an unsatisfactory drain field or a cracked tank, only for the issue to surface once the buyer's inspector gets involved.

By then, the seller is often on the back foot, negotiating repairs or a price reduction under a ticking clock.

A Deal That Fell Apart

Rebecca has seen firsthand how serious this can get. In one transaction, a septic inspection turned up several significant concerns. Once the buyer weighed the cost and scope of the needed repairs, they decided to walk away from the deal entirely.

It's a reminder that septic issues are not just a paperwork problem. They can be the difference between a closed sale and a canceled one.

What Sellers Should Do Before Listing

The fix is simple, even if it's often overlooked. Rebecca recommends that sellers have their septic system professionally inspected before the home ever hits the market.

"This gives them an opportunity to address any legitimate concerns in advance and avoid unexpected issues once the home is under contract," she said. A recent inspection report also gives buyers useful information up front, even though many will still choose to have their own inspection done.

Getting ahead of the process means sellers control the timeline and the budget, instead of scrambling once a buyer's inspector finds something.

What We See in the Field

We asked our own team what actually turns up during a pre-sale septic inspection, and the list is fairly consistent from property to property:

Cracked or broken piping and manholes
Damaged or missing baffles
Drain field concerns, such as unusually lush grass or wet spots in the yard that signal a saturated drain field
Roots that have grown into the pipes or the tank itself

None of these are unusual, and none of them have to derail a sale, as long as they're caught early.

How Long an Inspection Takes

A typical septic inspection runs anywhere from an hour and a half to three hours, depending on the system. Some properties need a bit more digging, literally, if components are hard to locate.

Our advice is to schedule the inspection three to four weeks before closing. That window gives enough time to inspect the system, deliver a report, and complete any necessary repairs before the deal is set to close.

Red Flags Sellers Should Watch For

Some warning signs are visible long before an inspector ever shows up. Keep an eye out for:

Little to no record of maintenance or pumping
Lush, unusually green patches over the drain field
Sewage odors inside or outside the home
Slow draining sinks, tubs, or other appliances

If any of these sound familiar, it's worth getting the system checked before a buyer's inspector finds it for you.

What Repairs Actually Look Like

Not every septic issue means a major project. A general baffle repair, for example, is often a one-day fix. The tank is emptied and a technician enters the tank to secure the new baffle.

Drain field issues are a different story. Depending on severity, those repairs can take anywhere from several days to several weeks. If permitting is required, timelines can stretch further while waiting on township approval or availability from the Sewage Enforcement Officer.

Both Rebecca and our team agree on the same core piece of advice: don't overlook the septic inspection, on either side of the deal. As Rebecca put it, "Sellers should be proactive and transparent, because identifying and addressing concerns early can help prevent delays, renegotiations, or a terminated transaction."

A septic system doesn't have to be the thing that sinks your sale. With the right inspection at the right time, it can just be one more box checked on the way to closing.
