Most people never look in their crawl space, so the problems down there announce themselves upstairs instead. Here are the seven signs we tell Halifax-area homeowners to watch for. If you've got two or three of these, the crawl space is almost certainly the cause.
1. A musty smell on the main floor
This is the big one. A persistent musty or damp smell that air freshener doesn't fix is usually crawl space air rising into your home. The smell is mold and damp, and you're breathing it.
2. Cold floors in winter
If your floors are cold no matter how high the heat is, there's probably a crawl space full of cold air sitting right underneath them. An unsealed, uninsulated crawl space is basically outdoors below your floorboards.
3. High humidity inside the house
Windows that sweat, a clammy feeling, or a hygrometer reading above 55 percent indoors often trace back to moisture rising from below.
4. Bouncy or sagging floors
Floors that flex, bounce, or slope can mean the joists or supports under them have been weakened by long-term moisture. That's a structural problem worth catching early.
5. The rest of the list
- Mold or a white, powdery growth visible on the floor joists
- Condensation or standing water under the house after rain
- Higher heating bills than a similar home should have
- More dust mites or worse allergies than you'd expect
What to do about it
Any one of these is worth a look. We offer a free crawl space assessment, we go under, check the moisture, the framing, and the insulation, and tell you straight what's going on. In newer Bedford homes especially, people are often surprised the crawl space was never sealed, and that it's the reason their floors are cold.
