What are the Signs of Dampness in a Crawl Space?

Recognizing dampness and humidity in a crawl space is easy when you know the signs. Condensation is a very strong sign that you have issues with moisture, but there are many others that you should be aware of.

Signs in Your Crawl Space

When inspecting your crawl space, there is a number of things that you should look for. First and foremost, the presence of standing or pooling water in any part of your crawl space is a warning sign. The amount of water, and where it is found, can also help in identifying the most likely cause. If you can see a steady drip or stream of water, for example, it is very likely that there is a plumbing leak nearby.

Condensation falls into this category, but you should also consider how the air in your crawl space feels. Most of us recognize the feeling of extreme humidity. The sticky, slightly thick feel to the air is instantly recognizable. Of course, you should also consider the smell of the space and look for the presence of fungal and bacterial growths. If you see mold of any kind, it is pretty much certain you have an issue with dampness and humidity.

Signs in the Rest of Your Home

You will also be able to find signs of crawl space dampness and humidity in your wider home. This is especially the case if you have a non-encapsulated or waterproofed crawl space. The stack effect will see to it that the humidity and dampness in your crawl space circulate with the air in your home. This means that you are likely to see mold, mildew, and stains spreading in your home when the humidity becomes incredibly high.

On a less tangible note, you are also likely to notice fluctuations in temperature and energy usage around your home. If there are leaks in your plumbing system contributing to your crawl space humidity, you may also notice changes in your water pressure and fluctuations in temperature. This can cause your energy bills to rise over time as your HVAC and water heating systems struggle to provide a consistent result.
