What Lies Beneath: A Basement Story Every Homeowner Should Hear

A couple of years ago, I received a call from a potential seller who was thinking about putting their home on the market. During that conversation, he mentioned there had been some water damage in the basement that was being taken care of, but he wanted to get the process started.

About six months prior, in the middle of winter, his basement had flooded. The interior temperatures dropped, a pipe froze and burst, and unfortunately, no one realized it right away as he had been out of town.

By the time the issue was discovered, the basement had filled with three to four feet of water. What started with frozen pipes didn't just affect the basement. The damage extended throughout the home, impacting plumbing lines that ran all the way to the second floor.

The cleanup was extensive. Pipes had to be replaced, the basement had to be completely gutted, and the mechanical systems, including the furnace, were damaged beyond repair. Because the water had been sitting for months, mold had begun to set in, and the remediation process alone became a major project before any rebuilding could even begin.

Situations like this are rare, but they are a good reminder of how quickly water damage can escalate when no one is around to catch it early.

If you travel during the winter or leave your home for extended periods, it's worth putting a few safeguards in place. Have someone check on the house, consider a temperature monitoring system, and make sure your heating and plumbing systems are functioning properly before you leave.

Basements are often out of sight, which means problems can go unnoticed until they become much larger than they needed to be.

This month in the Home Series, I'm focusing on what homeowners should know about basement moisture, foundations, and early warning signs, along with how to stay ahead of issues before they escalate.

Because sometimes what lies beneath your home is just as important as what you see every day.

If you're ever unsure what you're seeing in your own home, I'm always happy to take a look or point you in the right direction.

Frequently Asked Questions

How do I know if my basement has a moisture problem before it becomes a bigger issue? The early signs are often subtle. Look for white chalky residue on concrete walls (called efflorescence), a musty smell that lingers even after the space is aired out, rust stains near floor drains or on metal components, and paint that's peeling or bubbling on foundation walls. In Vermont homes, especially older ones, a little dampness after a heavy rain isn't unusual, but if you're seeing recurring staining or smell mold, that's worth investigating before it progresses.

What temperature should I keep my home in winter if I'm away for an extended period? The general guidance is to keep the thermostat no lower than 55 degrees Fahrenheit when a home is unoccupied. That said, in a Vermont winter, heating system reliability matters just as much as the setting itself. If you're leaving for more than a few days, make sure someone is checking the house in person, not just relying on a thermostat app. A frozen pipe can happen fast, and a monitoring system that alerts you to temperature drops is a smart layer of protection.

If a home had water damage in the past, does that automatically make it a bad purchase? Not necessarily. Past water damage that was properly remediated, documented, and repaired can be a manageable part of a home's history. What matters is how it was handled. During a home purchase, a licensed inspector can assess whether the remediation was done correctly, whether there are lingering signs of mold or structural compromise, and whether the source of the water intrusion was actually resolved. I always encourage buyers to ask for documentation of any remediation work and to take their time with this part of the due diligence process.

Are Vermont basements more prone to moisture issues than homes in other regions? Vermont's climate, soil conditions, and older homes do create some specific considerations. Freeze-thaw cycles put stress on foundations over time, and many Vermont homes were built before modern waterproofing methods were common. Homes on hillsides or in low-lying areas may also experience seasonal groundwater pressure. None of this means a Vermont basement is a liability, but it does mean that understanding your specific property, its age, drainage, and foundation type, is part of being an informed homeowner here.

When should a basement concern be evaluated by a professional rather than handled as a DIY project? If you're seeing active water intrusion, significant mold growth, cracks in the foundation that are wider than a hairline or appear to be shifting, or any indication that a mechanical system was affected by water, those are situations for a licensed professional. A home inspector, structural engineer, or certified mold remediation specialist can give you an accurate picture of what you're actually dealing with. DIY fixes on surface symptoms without understanding the underlying cause can make the problem harder and more expensive to address later.
