5 Signs Your Crawl Space Needs A Dehumidifier

Did you know that the air from your crawl space moves up and into your home? That means that any issues your crawl space is having - from air quality to mold - can affect your living spaces as well.

What’s worse is that, when left untreated, crawl space issues can affect the structural integrity of your home, which can lead to untold costs to fix.

What do all of these issues have in common? Too much moisture in your crawl space.

A dehumidifier can help. If you’re experiencing any of the following issues in your home, it’s a good sign that you need a crawl space dehumidifier.

Here are 5 signs your crawl space needs a dehumidifier:

  1. Poor air quality

  2. Visible condensation

  3. Mold

  4. Musty smells

  5. Structural damage

1. POOR AIR QUALITY

Remember that air from your crawl space moves up and into the living spaces in your home, so any poor air quality in your crawl space amounts to poor air quality in your home too!

Poor air quality can cause any number of issues for you and your family, including asthma development, allergic reactions, and even flu-like symptoms.

A crawl space dehumidifier will help alleviate moisture, which will help improve overall air quality. 

2. CONDENSATION

Seeing obvious condensation in your crawl space is not uncommon for those spaces that have an HVAC system or other equipment in them. However, that’s a recipe for other issues down the road (as you’ll read more about soon).

Dehumidifiers alleviate the moisture buildup and condensation from these systems so you don’t end up experiencing any other issues from your crawl space.

3. MOLD

It’s no secret that humid, dark environments are the perfect recipe for mold to thrive. And of course, mold is the last thing any homeowner wants to see within their walls - or within their crawlspace.

It’s key to first professionally mitigate any mold you have, so that it doesn’t reoccur. Then, keep your crawl space dry with a dehumidifier, which will drastically decrease the chance of mold and mildew growth in the future.

4. MUSTY SMELLS

A musty odor in your crawl space (and often extending into your home too) can be caused by mold, mildew, and the toxins they release, but is ultimately a result of excess moisture in the crawl space. 

If you start smelling musty odors and can’t find the culprit, then look to your crawl space.

Then, install a dehumidifier to ensure a dry crawl space and no more musty smells.

5. STRUCTURAL DAMAGE

The most extreme sign you need a dehumidifier is if you start to see signs of structural damage. Whether due to mold growth or pest infestation, dark, damp crawl spaces provide an opportunity for extraordinary damage to your home if left unchecked.

You might see rust on metal fittings or support beams, sagging and moist insulation, buckling floors, rotting or damaged wood, or swelling in doors and windows.

Again, all of these issues start with too much moisture in your crawl space. That’s why using a dehumidifier to take care of excess humidity is so critical for the longevity of your home.
