It is important to keep your home's structure sturdy for it to last for a long period of time. Most homeowners, however, don't realize that their home is actually in great peril because of the humidity in their crawl space.

In order to keep a home's structure sound, it is important to always have a dry foundation. Homeowners can do so by using a dehumidifier to keep everything toast and dry. Here are a few FAQs about humidity in crawlspaces:

1. Why is Your Crawl Space So Wet?

A crawlspace may get wet because water found a way into it. Most humidity problems in crawlspaces are caused by cracks in the home's foundation or walls. These cracks actually let water inside your home and make it feel damp.

Some other causes may include improper ventilation, lack of regular maintenance and poor drainage systems. It is also important to take care of the dirt floor in crawl spaces by sealing it to avoid moisture from coming inside the home.

2. The Consequences That Caused by Wet Crawl Space

A wet crawlspace is always a bad sign about a house's structure. If you have a wet crawlspace, you can suffer consequences like mold and mildew growth. If the crawlspace is moist, the organic matter found in the moisture makes it perfect for mold and mildew to populate the space. As we all know, mold and mildew can bring about many health problems to homeowners.

Aside from mold buildup, the house's structure may also deteriorate because of moisture. If the structure of the house weakens, more cracks may appear on the walls and allow even more water accumulation into the home. Aside from that, it can also allow pests like rodents and other insects to enter the area.

Also, a large percentage of air that goes in and circulates the home comes from the crawlspace. The air below your home seeps through your floors and around your heating and air ducts. Thus, the air surrounding your home is going to be unsafe. Hence, if the air below the house is riddled with bacteria because of the mold and mildew buildup, the air you are breathing inside your home may not be safe for your health.

Some of the health problems related to this type of problem include headaches, respiratory complications as well as fevers. Hence, it is very important to keep your crawlspace dry and safe from mold or mildew buildup.

3. How Will A Crawl Space Dehumidifier Help?

The consequences mentioned above can easily be addressed by keeping the crawlspace dry. Moisture and water can cause a lot of problems. Wet insulation, as well as standing water must be extracted. There are various ways to do so, but experts believe that using a dehumidifier would be the best option.

Most homeowners use vents to keep their crawlspace dry. However, experts believe that this is not enough because it can add more damage to the already impaired walls. Installing a vent entails putting a hole in the wall for the vent to get into. This may cause even more cracks to the wall and collect even more water at the edge of your home.

Other homeowners put up gravel and vapor barriers to keep humidity levels low. This, however, does not consider the fact that moisture can still find a way into the crawlspace through the dirt floor. A vapor barrier cannot keep the water out because of the already existing cracks that continuously let water in. Therefore, it is important to get a dehumidifier that can do just that.

What to Look for in Buying Dehumidifier for Crawl Space

There are a lot of dehumidifiers in the market today. If you want to find one for your home, here is a list of things you should consider:

  • Price - Never go over your budget. Not all dehumidifiers come with a big price tag. If you do your research, you will surely find one that is within your living expense budget. It is harder to get into debt just because of your dehumidifier purchase. This product is aimed to protect your home and not be the cause for you to lose your home because you can no longer handle your living expenses upon its purchase.
  • Size - Dehumidifiers usually come in bulky sizes. So, it is best to choose a dehumidifier that will perfectly fit in your home and address your needs. It is also best to buy a portable dehumidifier because it can be easily transported from one place to another. A portable dehumidifier will be perfect if you need to change homes. You can easily ship it to your new address instead of living it behind your old home.
  • Other Features - Most dehumidifiers come with features like air filtration, automatic switch, remote control and alarms. It is best to look into the added features of the product before purchasing. Air filtration is best for highly humid basements to ensure that bacteria build up will be avoided in the space.
  • Energy Consumption - Dehumidifiers are big machines that can consume large amounts of energy. Again, it is better to stay within your means. So, if you buy a machine that consumes huge energy power, you may end up with bigger utility bills. Hence, it is important to check the energy consumption of the products you are looking into before buying.
