Crawl Space Waterproofing


Introduction to Crawl Space Waterproofing

Waterproofing your crawl space involves closing off the area so that water and other contaminants can't seep in. Your home's plumbing and electrical systems may be accessed through the crawl space, making it a crucial component of the building's structure. One of the most common causes of water damage and mold growth is negligence in this area.


Your home's structural safety and your family's health are both dependent on the quality of the work done to waterproof the crawl space. It can also help you save money on energy costs and enhance the quality of air within your home by reducing the amount of moisture in the air.


Crawl space waterproofing can be accomplished through the use of a variety of methods, including the installation of vapor barriers, drainage systems, sump pumps, and dehumidifiers. The size, location, and severity of the moisture problem in your crawl space will all play a role in determining the best method for your property.


Below, we'll break down each method and give you some pointers on how to use them to waterproof your crawl space and maintain a healthy, dry environment in your home.

Benefits of Crawl Space Waterproofing in Charleston, SC

Crawl space waterproofing provides several benefits for homeowners, including:

  • Protection from Water Damage: Crawl space waterproofing protects your home from water damage caused by heavy rainfall, snowmelt, or groundwater. It prevents moisture buildup, which can cause mold growth, wood rot, and foundation issues.

  • Improved Indoor Air Quality: Moisture in the crawl space can lead to the growth of mold and mildew, which can cause respiratory issues and other health problems. Crawl space waterproofing eliminates moisture, improving indoor air quality and reducing the risk of health hazards.

  • Energy Efficiency: A damp crawl space can affect your home's energy efficiency, causing your heating and cooling system to work harder. Crawl space waterproofing can help reduce energy bills by preventing dampness and humidity in your home.

  • Increased Home Value: Crawl space waterproofing can increase the value of your home by providing a dry, healthy, and structurally sound foundation.

  • Prevent Pest Infestations: Damp crawl spaces are a breeding ground for pests such as termites, rodents, and insects. Crawl space waterproofing can help prevent these pests from entering your home, reducing the risk of damage and potential health hazards.


In summary, crawl space waterproofing is a wise investment for homeowners looking to protect their home's structural integrity, improve indoor air quality, and reduce energy bills. It provides numerous benefits that not only improve the quality of life in your home but also increase its value.

Types of Crawl Space Waterproofing

Waterproofing a crawl space can be done in a number of ways, and the method that works best for your home will be determined by the extent of the moisture problem and the construction material of your home's foundation. Common methods of waterproofing a crawl area include:

  1. Vapor Barriers: A vapor barrier is a plastic sheet installed on the crawl space floor and walls to prevent moisture from entering your home. It is a cost-effective solution and relatively easy to install. The vapor barrier also helps to keep the crawl space clean and reduces the risk of pests infestation.
  2. Drainage Systems: If your home is located in an area with heavy rainfall or high groundwater levels, a drainage system may be necessary. A perimeter drain system collects water from the walls and floor and directs it to a sump pump, which pumps the water out of your crawl space.
  3. Sump Pumps: A sump pump is a device that collects and removes water from your crawl space. It is usually installed in a sump pit and activated by a float switch. Sump pumps are essential if you have a high water table or if your crawl space is prone to flooding.
  4. Dehumidifiers: Dehumidifiers help to reduce humidity levels in your crawl space, preventing mold growth and improving indoor air quality. They are especially useful in humid areas or crawl spaces with poor ventilation.
  5. Exterior Waterproofing: Exterior waterproofing involves excavating around the foundation of your home and applying a waterproof coating to the walls. This technique is more expensive and time-consuming but provides the most effective long-term solution for waterproofing your crawl space.


In conclusion, there are a number of considerations that go into settling on the best method for waterproofing a crawl space. If you want your house to be a healthy, dry place to live for you and your family, you should talk to an expert about the best course of action.

Preparing for Crawl Space Waterproofing

There are a few crucial things that homeowners need to do before starting the waterproofing process in their crawl space:

  1. Inspect the crawl space: Conduct a thorough inspection of your crawl space to identify any signs of moisture, water damage, mold growth, or pest infestation. It is also essential to check the foundation for any cracks or gaps that could allow moisture to seep in.
  2. Clean the crawl space: Remove any debris, mold, or mildew from the crawl space. This will allow the waterproofing material to adhere correctly and prevent the growth of mold or mildew in the future.
  3. Address any plumbing or electrical issues: If there are any plumbing or electrical issues in the crawl space, such as leaky pipes or faulty wiring, address these issues before beginning the waterproofing process.
  4. Determine the best waterproofing technique: Based on the inspection of your crawl space and the severity of the moisture problem, determine the best waterproofing technique for your home.
  5. Hire a professional: While some homeowners may choose to DIY crawl space waterproofing, it is often best to hire a professional. A professional can assess your crawl space's unique needs and ensure that the waterproofing process is done correctly and efficiently.


Homeowners can increase the likelihood that their crawl space waterproofing project will be a success by following these procedures before getting started. Homeowners can have a dry, healthy house for years to come if they take the necessary precautions.

  2. Drainage Systems: The cost of installing a perimeter drainage system ranges from $2,000 to $6,000, depending on the size of the crawl space and the complexity of the installation.
  3. Sump Pumps: The cost of installing a sump pump ranges from $1,000 to $5,000, depending on the size of the pump and the difficulty of the installation.
  4. Dehumidifiers: The cost of installing a dehumidifier ranges from $1,500 to $3,000, depending on the size and capacity of the unit.

DIY Crawl Space Waterproofing

Even though it's best to have a professional handle crawl space waterproofing, some homeowners may try it themselves. For those that want to do it themselves, here are some suggestions for waterproofing a crawl space:

  1. Clean the crawl space: Remove any debris, mold, or mildew from the crawl space. Ensure that the area is dry and clean before proceeding with the waterproofing process.
  2. Seal any cracks and gaps: Use caulk or expanding foam to seal any cracks and gaps in the crawl space walls or foundation. This will prevent moisture from seeping into your home.
  3. Install a vapor barrier: Lay a plastic vapor barrier on the crawl space floor and walls, overlapping the seams by at least 6 inches. Secure the barrier to the walls using adhesive tape or mechanical fasteners.
  4. Install a dehumidifier: Purchase a dehumidifier and place it in the crawl space to reduce humidity levels and prevent mold growth. Ensure that the dehumidifier is appropriately sized for your crawl space.


Waterproofing a crawl space on your own can save money, but it's important to remember that it's also a difficult and time-consuming project. And if the waterproofing isn't done properly, it can cause more issues and cost more money in the long run. This is why it is best to get an expert's opinion and make sure the job gets done right.

Common Crawl Space Waterproofing Issues

There are certain frequent concerns that homeowners may encounter even though waterproofing their crawl space can avoid moisture problems and enhance indoor air quality. Crawl space waterproofing problems typically include the following:

  1. Insufficient Drainage: If the crawl space has poor drainage or is not graded correctly, water may accumulate in the crawl space, leading to moisture problems and potential damage to the foundation.
  2. Inadequate Vapor Barrier: If the vapor barrier is not installed correctly or is not thick enough, it may allow moisture to seep into the crawl space, leading to mold growth and poor indoor air quality.
  3. Improper Sealing: If the crawl space walls or foundation are not properly sealed, moisture can seep into the crawl space, leading to mold growth and structural damage.
  4. Improper Ventilation: If the crawl space is not adequately ventilated, moisture can accumulate and lead to mold growth and poor indoor air quality.
  5. Inadequate Dehumidification: If the dehumidifier is not appropriately sized or is not maintained correctly, it may not effectively reduce humidity levels in the crawl space, leading to moisture problems and potential damage to the foundation.


If you run across any of these problems, fixing them quickly will save you money and hassle down the road. The best way to find a permanent solution to moisture concerns in your home is to consult with a professional contractor to inspect your crawl space, identify any problems, and then implement a waterproofing system.
