Your foundation is one of the most important parts of your home. It keeps everything level, stable, and safe. But over time, things can go wrong, and the signs aren’t always obvious.
If you live in Boston, you know that older homes, freezing winters, and heavy rains can all take a toll on your foundation. So how do you know when it's time to take action?
This guide will walk you through the warning signs and help you decide when to call a Boston foundation repair expert like JMS Masonry.
TLDR: Some signs that your foundation could use a professional assessment include cracks near windows and doors, long zigzag cracks in drywall, doors and windows that don’t close/open properly, or tilted or uneven floors.
Why Your Foundation Matters

The foundation is what your house is built on. It supports the walls, floors, and everything else. If it starts to shift or crack, it can lead to big problems.
Some signs are easy to miss or seem harmless at first. But catching these early can save you money and protect your home from serious damage.
Cracks in Walls or Floors
What to Look For:
Cracks near doors or windows
Long or zigzag cracks in drywall
Cracks in basement floors or outside brick
Small hairline cracks are usually not a problem, but larger cracks or ones that grow over time could mean the foundation is moving.
At JMS Masonry, we inspect cracks to see if they are harmless or signs of deeper issues. If you're unsure, it's better to get a second opinion than to wait. Reach out today!
Doors and Windows That Stick
What to Look For:
Doors that don’t close right
Windows that are hard to open
Gaps between frames and walls
When your foundation shifts, it can cause your doors and windows to go out of alignment. If you start noticing this in more than one area of your home, it’s time to take a closer look.
Uneven or Sloping Floors
What to Look For:
Floors that tilt or feel uneven
Furniture that rocks or rolls on its own
Boston homes, especially older ones, often settle over time. But if your floors start to slope suddenly or you feel like you’re walking downhill in your house, there could be a bigger issue.
Water in the Basement

What to Look For:
Wet spots or puddles in the basement
Mold or musty smells
Cracks that let water in
Water is one of the biggest threats to your foundation. Boston weather can bring heavy rain and melting snow, and if water isn’t draining properly, it can cause cracks or even shift your foundation.
Gaps Around the House
What to Look For:
Space between walls and the ceiling
Separation between the chimney and the house
Gaps between bricks or concrete blocks
These are all signs that something might be shifting beneath your home. It’s especially important to pay attention to these if you live in a historic or older Boston property.
