New England winters can be bone-chilling. That kind of cold doesn’t just leave you shivering; it can put your home’s plumbing at risk, too. Frozen pipes are a common winter headache, and a burst pipe can lead to costly water damage.

One simple way to stay ahead of it? Consider adding water sensors or an automatic shut-off system. Homes with in-line shut-off systems have seen a 96% drop in water-leak claims and a 72% reduction in claim severity.

Placing sensors near your water heater, under sinks, or along main lines can help catch leaks early and save you from major winter stress. A little prep now can go a long way when the temps really drop.

The current weather conditions—including freezing temperatures, bright sunlight, and heavy snowfall—set the stage for ice dams. A cycle of melting snow during the day and refreezing at night can cause a dam to form, leading to significant structural damage to your roof and water backing up and seeping into your property.

To help property owners mitigate this risk, we have developed a comprehensive resource outlining preventive measures to avoid this winter hazard and protect their property.

Did you know water damage can be one of the costliest home emergencies? An inexpensive water sensor or water shut-off system can offer strong protection.

A recent U.S. study found that homes equipped with in-line water shut-off systems experienced a 96 percent decrease in paid water leak claims and a 72 percent reduction in claim severity compared to homes without the systems.

By detecting leaks early or shutting off water automatically, sensors and shut-off systems help homeowners minimize damage before it spreads. Placing sensors in key areas, such as near water heaters, under sinks, or along main lines, adds an extra layer of protection and peace of mind.

Meet Dan Valeri, our dedicated Field Representative serving New Hampshire. For 35 years, Dan has been a steady presence at The Andover Companies, building strong relationships and assisting our agency partners across the Granite State.

Dan began his career as an Assistant Personal Lines Underwriter in 1989. After working in Underwriting for a few years, he knew he wanted a job in the Andover Field Department. “I thought it was a perfect match for me and something that could last. To get the New Hampshire job was a bonus.”

What makes Dan’s 35 years especially meaningful are the relationships he’s built. He appreciates the number of close friends he has among his NH agents: "I trust them, and they trust me. I wish I could list a bunch of names, but my buddies know who they are.”

When asked what he values most about Andover, Dan points to the company’s loyalty. During tough times in New Hampshire, especially the devastating ice storms, he recalls strong support from company leadership. That support meant a great deal, especially at a time when he had three young children at home.

Outside work, Dan enjoys life in Portsmouth, which he considers a tremendous town filled with great bars and restaurants. He particularly likes Portsmouth's "incredible spontaneous vibe," saying that often, he and his wife Robin will take a walk into town on a Saturday afternoon with no plans and return several hours later after bumping into friends all day.

He also enjoys traveling, walking, and tackling home projects. “I know this sounds crazy, but I enjoy painting. Not painting art, but interior painting. I’m currently working at my boys’ townhouse in Dover and plan to paint every single room in their home. When I’m done with a room, it gives me tremendous satisfaction seeing what I’ve accomplished."

And if he could plan his perfect day? “The perfect day would be for me and Larry Bird to go to a Red Sox Game with great seats right above the Sox dugout and talk all day and enjoy beers together!”

After 35 years, Dan continues to bring dedication, insight, and a personal touch to everything he does. We’re proud to celebrate this work anniversary with him and grateful to have him on our team.
