Old Homes, Harsh Weather, and Foundation Damage—Welcome to I-95 Living

The stretch of I-95 from Maine to Massachusetts winds through some of New England’s most charming and historic towns—from Falmouth, ME, and Portsmouth, NH, to Andover, MA. While the area is known for its natural beauty, it also sees some of the worst basement issues in the Northeast. 

Many environmental factors mean water in basements for coastal Northern New England isn’t just a possibility—it’s a regular occurrence.

At Groundworks, we’ve repaired thousands of wet basement issues through expert basement waterproofing solutions. If your home sits along this heavily traveled corridor, here are the top basement issues along I-95 from Maine to Massachusetts you need to watch for.

Top 5 Basement Issues Along I-95 from Maine to Massachusetts

1. Water Intrusion & Flooded Basements 

In southern Maine towns like Falmouth and Yarmouth, the proximity to the coast, combined with frequent rain and spring snowmelt, makes wet basements a constant concern. Many homes here were built decades ago and lack modern drainage or waterproofing systems, leading to frequent water in basement situations during even moderate storms.

Signs You Might See:

2. Humidity and Mold Growth

In Stratham and Portsmouth, many basements and crawl spaces stay damp year-round due to poor ventilation and a naturally humid climate. The result is musty odors, mold growth, and indoor air quality issues that affect the rest of the home.

Why It’s Common Here:

3. Foundation Cracks & Structural Shifts 

The historic charm of Newburyport comes with a trade-off: many homes are over 100 years old and built on stone or brick foundations that naturally deteriorate over time. These materials are especially vulnerable to freeze-thaw cycles and shifting ground, resulting in horizontal, vertical, or stair-step cracks in basement walls.

What to Look For:

4. Sump Pump Failures 

Sump pumps are essential in communities like Andover and the surrounding North Shore, MA, area, but many homeowners learn the hard way that one pump isn’t enough. During major storms, power outages are frequent, and a failed sump pump can lead to a flooded basement in hours. That’s why reliable backup systems and expert sump pump service in North Shore, MA, are so important.

Common Triggers:

  • Power loss during Nor’easters
  • Pump is overwhelmed by water volume
  • Float switch failure or mechanical failure

5. Wet Crawl Spaces

Crawl spaces are common in Yarmouth, Stratham, and Newburyport and often neglected. They collect moisture and contribute to wood rot and pests.

Warning Signs:
