Crawl Space Humidity Solutions For Your Home

Have you ever thought about crawl space humidity? You're very likely to have never thought about crawl space humidity. Who would? Crawl spaces are not dinner table conversations. Humidity is also not a good idea unless it is extremely cold. What happens when you combine the two? Crawl spaces and humidity don't make a good combination.

Humidity can cause damage to your health and your home

But humidity in crawl spaces can cause serious health problems and even damage to your home's structure. Mold can be a serious problem when there is humidity. Mold can lead to asthma attacks and allergy symptoms. Mold could be the cause of your symptoms, especially if you have been coughing or sneezing quite often. It can also cause skin irritation.

This is bad enough. But mold can also be a sign that there is an even greater problem: excessive humidity. The air is saturated with water, which is what excess humidity means. Mold can lead to wood rot and metal rust. These conditions can cause serious damage to a living space, as well as impair the functionality of metal or wood-based home products. Have wooden beams? They could rot and collapse. Are metal-air conditioners available? They could be easily damaged by rust.

Pests can also be caused by excess humidity and mold. Love Your Space Termites call rotting wood their home. They can cause severe damage to wood, causing serious structural problems.

Your crawl space is the problem

Humidity is bad, and crawl spaces make it worse. Although crawl spaces can be found anywhere in a house, they are most often located in basements or attics. Crawl spaces are rarely inspected by the general public. Unless you have a specific repair request for your crawl space, it will likely go uninspected for many months, years, or even decades.

Therefore, if there is a humidity problem, it is very likely that it will go unnoticed. It won't matter if a mold problem is added to the mix.

You should know if there is a problem with your refrigerator. It is easy to see the problem and throw away the infected item.

Mold found in an unidentified area will not be visible, and the conditions that lead to it won’t be corrected.

Every six months, it's a good idea to conduct a walk-through inspection of your house. This is a common home inspection that includes checking pipes, faucets, and roofs. Almost nobody inspects crawl spaces. It is a good idea for them to be added to the list.


What if you have symptoms similar to an allergy? Or if you find yourself in a crawl space with moldy spores? There are two things you can do. The first is to understand the causes of mold growth. Learn how to stop it.


Why does an area develop mold?

In areas with too much water, mold can grow. This is the easy part.

Why is your crawl space flooded? There are four possible reasons why your crawl space has too much water:

  1. Humidity
  2. Leakage of water from one location. Make sure to check pipes and drains. Even a small leak in a pipe could cause enough moisture to clog pipes, allowing mold to thrive.
  3. The ground is losing moisture. This is especially true in basement crawl spaces. Every night, moisture evaporates from the soil. Mold can develop if your crawl space is in a vulnerable area.
  4. The outdoor air is condensing and becomes moisture when it reaches the crawl space.

Reassuring, isn't it? Mold can only be caused by a few things, but they are all easily fixed.

How to Fix the Issue

To prevent mold growth, you need to address the problem at its source. Here's how:

  1. A dehumidifier can be a great idea if you live in a humid environment. Regular home maintenance should include a crawl space inspection every six months to look for signs of mold.
  2. Conduct a thorough inspection of pipes and drains. Repair any leaks that you find. A thorough inspection of your pipes and drains at least once every six months is a good way to prevent problems from happening.
  3. The crawl space can be encapsulated and the vents sealed. Professionals are best to do this so moisture doesn't get into the crawl space.
  4. Condensation can occur when outdoor air is allowed to enter through windows located near the crawl space. It will be fixed by closing the windows.

Although crawl space humidity is not something most people consider a problem, it can lead to mold. Mold can cause serious illness and property damage. Check your crawl space regularly for mold and excess moisture. After all, prevention is better than cure.
