5 Unusual Causes of Dampness in a Home

5 Unusual Causes of Dampness in a Home


It’s the middle of winter, and yet you find yourself shivering in your home that has been closed up all day while you were at work. Why can’t your house seem to stay warm? If you’re suffering from mildew, humidity, or musty smells in your home, then it’s likely that your home suffers from an excessive amount of moisture that has built up over time.


1) Condensation

When warm air hits cold glass, condensation occurs. While you may love a foggy windshield when it’s 75 degrees outside, most people don’t like their windowpanes doing an impression of a wading pool. Condensation is typically found on windows and screens, but can also appear on walls or light fixtures. The fix is simple: wipe down your windows!


2) Moisture from Above

If you’re suffering from an unusual degree of damp or condensation, check your roof for leaking gutters and downpipes. If you find any problems, it could be time to call in a professional. Similarly, water penetration can come from leaks at external walls as well as poorly fitted doors and windows.


3) Mold or Mildew

Too much moisture is a common culprit for causing dampness, but mold and mildew can also lead to it. Mold thrives on water and can cause health issues if you have mold growing inside your home. When most people think about mold, they think about bathroom grout or roof shingles—but that’s far from the only place you can find it.


4) Reticulation Overflow Water

When your drains get blocked, it’s usually easy to tell what caused it: a clogged toilet or sink drain. But reticulation overflow water looks and smells just like standing water, which means that when your drains start overflowing for no apparent reason, you can’t necessarily point at a clog and say there! I knew it!


5) Roof Leaks into Downpipe, Gutters or Downspouts

Leaks from gutters and downspouts on to your home’s exterior can cause dampness, which is why it’s important to make sure your gutters are checked for debris and leaves at least twice a year. Also, check your roof for potential leaks—like chips or cracks—and be sure that shingles aren’t worn out or missing.
