Are you battling against moisture and mold in your crawlspace? Don’t let your home’s lower level fall victim to dampness, extreme humidity, or foul odors. Regional Foundation & Crawl Space Repair is here to arm you with the most powerful and efficient dehumidifying systems available – SaniDry™ Dehumidifiers.

What Is a Crawl Space Dehumidifier and How Does It Work?

A crawl space dehumidifier is a device designed to reduce moisture levels in the crawl space beneath a house or building. This area is often damp and prone to mold and mildew growth, making it a prime breeding ground for pests. A dehumidifier works by drawing in the humid air and passing it over a refrigerated coil, causing the moisture to condense and collect in a reservoir. The dry air is then discharged back into the crawl space, effectively reducing the overall humidity levels.

Apart from preventing mold and mildew, a crawl space dehumidifier can also help to lower energy costs by reducing the load on the air conditioning and heating systems. When the air is too humid, it can be difficult to regulate the temperature effectively, leading to increased energy consumption. A dehumidifier can also help to improve the air quality in the home, reducing the risk of respiratory issues and allergies.

When choosing a crawl space dehumidifier, it is important to consider the size of the space and the amount of moisture present. A larger unit may be required for larger crawl spaces or those with particularly high humidity levels. Additionally, it is important to choose a unit with a built-in pump or drainage system to prevent the reservoir from overflowing and causing water damage.

What Are the Benefits of Controlling Crawl Space Humidity?

Controlling crawl space humidity has numerous benefits that shouldn’t be overlooked. First and foremost, excessive humidity in crawl spaces can lead to mold and mildew growth, which can be a serious health hazard. Mold can trigger respiratory issues, allergies, asthma, and other health problems. Additionally, mold can also cause structural damage to homes and buildings, leading to costly repairs.

Maintaining low crawl space humidity levels can also help prevent pest infestations, including termites, cockroaches, and rodents. These pests can cause damage to homes and spread diseases, posing a threat to human health and property.

Controlling crawl space humidity levels can also help reduce energy consumption and lower utility bills. During the summer, high humidity levels can make homes feel warmer, making air conditioning systems work harder and longer to maintain comfortable indoor temperatures. The same thing happens during the winter. High humidity levels can make your home feel colder. By controlling crawl space humidity, air conditioning and heating systems can work more efficiently, leading to energy savings.

In addition to the health, structural, and financial benefits, controlling crawl space humidity can also improve indoor air quality. High humidity levels can lead to musty odors and unpleasant smells, affecting the comfort and well-being of occupants. By maintaining low humidity levels, indoor air quality can be improved, leading to a more pleasant and healthier living environment.

How to Choose the Right Dehumidifier for Your Crawl Space

Calculate the size of your crawl space

Before you purchase a dehumidifier, you need to determine the size of your crawl space. This will help you decide what capacity dehumidifier you need. To calculate the size of your crawl space, measure the length, width, and height of the space and multiply them together. For example, if your crawl space measures 20ft x 10ft x 3ft, the total volume is 600 cubic feet.

Choose the right capacity

Once you have calculated the size of your crawl space, you need to choose the right capacity dehumidifier. The capacity of a dehumidifier is measured in pints per day, and it refers to the amount of moisture the dehumidifier can remove from the air in a 24-hour period. As a general rule, you should choose a dehumidifier that can remove at least 70 pints of moisture per day for a crawl space that measures up to 1500 square feet.

Consider the humidity level

The humidity level in your crawl space will also determine the type of dehumidifier you need. If the humidity level is above 60%, you need a dehumidifier that can handle high humidity levels. Look for a dehumidifier that has a built-in humidistat, which will allow you to set the desired humidity level and have the dehumidifier automatically turn on and off to maintain that level.

Look for energy efficiency

Dehumidifiers can be energy hogs, so it’s important to choose an energy-efficient model. Look for a dehumidifier that has an Energy Star rating, which means it meets strict energy efficiency guidelines set by the Environmental Protection Agency.

Consider the noise level

If your crawl space is located near living spaces, you’ll want to choose a dehumidifier that is quiet. Look for a model that has a noise level of 50 decibels or lower.

Choose a durable model

Your crawl space is a harsh environment, so you need a dehumidifier that is built to last. Look for a model that is made of durable materials, has a sturdy construction, and comes with a warranty.

How Are Crawl Space Dehumidifiers Installed?

Step 1: Assess the Crawl Space

The first step in installing a dehumidifier in a crawl space is to assess the area. We will inspect the crawl space to determine its size, layout, and moisture level. We will also check for signs of mold, water damage, or structural issues that need to be addressed before installing the dehumidifier.

Step 2: Choose the Right Dehumidifier

Once the crawl space has been assessed, we will choose the right dehumidifier for the job. Factors to consider include the size of the space, the level of moisture, and the budget.

Step 3: Prepare the Crawl Space

Before installing the dehumidifier, the crawl space needs to be prepared. This may involve removing any debris, sealing any gaps or cracks, and laying down a vapor barrier to prevent moisture from seeping in from the ground.

Step 4: Install the Dehumidifier

With the crawl space prepared, it’s time to install the dehumidifier. We will mount the unit in a central location, making sure it’s accessible for maintenance and repairs. They will also connect the unit to a power source and any necessary drainage systems.

Step 5: Test and Monitor

Once the dehumidifier is installed, we will test it to make sure it’s working properly. We also install a hygrometer to monitor the humidity level in the crawl space and adjust the dehumidifier as needed.
Installing a dehumidifier in a crawl space isn’t a suitable DIY project. It is a complex process that requires expertise and experience.

Other Ways to Help Maintain Optimal Humidity Levels in a Crawl Space

Aside from using a dehumidifier, there are several other ways to help maintain optimal humidity levels in a crawl space. These include the following:

  • One of the most effective methods is crawl space encapsulation. This involves sealing the vents and covering the crawl space floor and walls with a strong, moisture-resistant material such as a polyethylene vapor barrier. This will prevent moisture from seeping into the crawl space and keep the area dry.
  • Another way to keep a crawl space dry is to install a drain tile system. This involves digging a trench around the perimeter of the crawl space and installing a perforated pipe that will drain water away from the foundation. The pipe is then covered with gravel and soil, allowing water to flow freely and preventing it from accumulating in the crawl space.
  • Regrading the yard can also be an effective way to maintain optimal humidity levels in a crawl space. This involves changing the slope of the ground so that water flows away from the foundation instead of towards it. This will help prevent water from seeping into the crawl space and causing moisture problems.
  • Using downspout extensions is another effective way to keep a crawl space dry. Downspout extensions are installed at the end of a downspout to direct water away from the foundation and prevent it from pooling near the crawl space. This will help keep the crawl space dry and prevent moisture problems.
  • Lastly, cleaning gutters regularly is an important step in maintaining optimal humidity levels in a crawl space. Clogged gutters can cause water to overflow and seep into the crawl space, so it’s important to keep them clean and free of debris. Cleaning gutters at least twice a year can help prevent moisture problems in the crawl space.

Proven Success: Case Studies and Testimonials

Hear from our satisfied customers who attest to the quality and durability of our crawl space dehumidifier installation services:

I am extremely satisfied with the foundation repair work and the crawlspace encapsulation done by Regional. I could not be happier with the final results. The crawlspace is clean as a whistle and dry as a bone now. The humidity levels in the house have already dropped significantly, and the crawlspace dehumidifier and sump pump have only been in place for 48 hours. The air circulating in the house no longer has the old musty, damp, mildew smell it used to have - the air is so much cleaner now. The foreman Bernard and his crew of Damien, Juan, and Cameron were extremely hard-working and efficient. They were professional in every way. They completed the job in the specified time frame, and they cleaned up the area completely when the job was finished. They were respectful of my property and they took pride in their work. Bernard kept me updated on each day's progress, and when the job was done he thoroughly explained how everything worked. I can't believe how they transformed my old crawlspace!
