If you walk around the perimeter of your home only to notice that your crawl space has open vents, chances are you may have a moisture problem on your hands. Past beliefs of installing crawl space vents to let air circulate throughout this space were later found to cause problems with moisture and pests. When outside moisture infiltrates your crawl space, it can cause a slew of issues underneath your home such as mold and mildew, and poor indoor air quality. Having open vents is also an easy entryway for pests to get in and out and cause damage. If this is the case at your home, it may be time for crawl space repair and encapsulation services from AquaGuard.

Is Crawl Space Repair and Encapsulation the Right Solution for Me? 

Nothing is worse than walking into an area of your home only to find damage has ensued. Since your crawl space is usually a part of your home that is rarely visited, any damage that occurs is likely to go unseen for quite a while. If you inspect your crawl space only to find a damp, musty, and humid environment, crawl space encapsulation is the solution for you. AquaGuard’s multi-step solution of encapsulating your crawl space will transform this once nasty and damp environment into a clean, dry, and usable space for storage. 

When moisture finds its way in, it can cause a series of problems throughout your home, some being more detrimental than others. Mold and mildew growth, poor indoor air quality, and excessive humidity can cause energy bills to skyrocket and create an unhealthy living environment for anyone in your home. In severe cases, moisture can also cause structural damage to your foundation, ruin the paint on your walls, and lead to condensation forming on windows and other surfaces.  

It’s important to clean up any water in your crawl space, but by encapsulating your crawl space with a high-quality, durable vapor barrier, you’ll improve your overall air quality and have a more energy-efficient home. At AquaGuard Foundation Solutions, we have over two decades of experience in engineering superior crawl space solutions for your home. Our 20-mil thick vapor barrier, combined with our state-of-the-art sump pumps, dehumidifiers, and interior drainage systems will ensure your home is protected against any moisture that tries to find its way in.  


Installing a dehumidifier is a crucial part in controlling crawl space moisture. A dehumidifier alone won’t fix all crawl space water and moisture issues, but in conjunction with a crawl space moisture barrier, a dehumidifier can ensure your crawl space is protected from mold damage. 

A moisture barrier, sometimes referred to as a vapor barrier, is just part of a complete crawl space encapsulation system. It is a durable liner used to prevent moisture from entering through exposed dirt floors and walls. Our crawl space moisture barrier is a crisp white, 20-mil, 7-layer poly-reinforced liner and is mold resistant, giving you the opportunity to transform your crawl space into usable storage space. 

Crawl space encapsulation refers to the process of waterproofing, insulating, sealing, and conditioning the crawl space to eliminate moisture and high humidity issues. The combination of installing an effective drainage system, insulating the crawl space, sealing floors and walls, and adequately dehumidifying the air not only prevents groundwater or wall moisture from entering the crawl space, but it also regulates crawl space humidity and temperature, often making it the most regulated and climate-controlled area in your home!

Though most crawl spaces are seldom used, a wet crawl space could mean problems for the floors above. It’s important to manage crawl space moisture levels to prevent rotting wood, mold growth, high humidity, pests, and other symptoms of a wet crawl space. Luckily, this is easy thanks to a number of crawl space repair and waterproofing solutions provided by AquaGuard Foundation Solutions.

Why Crawl Space Repair and Encapsulation Are Needed 

For the most part, if your home is newer, chances are it has some degree of crawl space waterproofing or encapsulation products in place. If it’s older, it may have exposed crawl space vents that can cause a multitude of moisture-related problems. In any case, it’s best to make sure your crawl space stays dry and clean. Here are a few reasons for needing your crawl space repaired and encapsulated.

Water Damage  

If you notice signs of moisture, it’s likely you already have problems with water damage in your crawl space. Things such as open crawl space vents, an exposed dirt floor, plumbing leaks, and foundation damage can all lead to your crawl space being inundated with water. Such damage can lead to mold growth, dry rot on your floor joists, elevated humidity in your home, and other damage. Before moving forward with an encapsulation solution, any prior damage needs to be addressed and repaired.

Mold and Mildew Growth 

As mentioned, any water in your home will likely lead to mold and mildew developing. In some cases, black mold can form, which is a particularly toxic strain of mold. This can lead to respiratory issues such as asthma and allergies and be especially harmful. It’s important to encapsulate your crawl space with a vapor barrier and install a dehumidifier to control the levels of humidity in your home.  

Musty damaged crawl space


Just like most home appliances, any waterproofing and encapsulation products have a point when they start becoming less effective. This is a natural process but can be detrimental to your home once it begins. It’s important to regularly have your home inspected for any signs of wear and tear and damage that could be harmful to its structure. This will protect your home and ensure it stays in good condition. 

Common Crawl Space Repair and Encapsulation Tips & Mistakes 

Over the years, we have seen and heard many repair and encapsulation myths for crawl spaces. If you’ve decided that your home can benefit from crawl space encapsulation, it’s important to consult a professional beforehand to determine the best solutions. Here are some helpful tips and mistakes to avoid when considering crawl space repair.  

Helpful Tips for Encapsulating Your Crawl Space 

  • Although your crawl space may be encapsulated with a high-quality vapor barrier, moisture can still find its way in and lead to mold growth. By combining a vapor barrier with an energy-efficient, self-draining dehumidifier, you can be sure that the humidity levels in your crawl space and home stay under control.  
  • By repairing and encapsulating your crawl space, you can save loads of money on your energy bills. During the summer, your HVAC systems usually go into overdrive due to the high temperatures outside, and the same goes for the wintertime. Many homes’ HVAC systems are located within their crawl spaces and by encapsulating yours, you will ultimately stabilize the temperature and reduce energy usage. This also decreases the wear and tear on your HVAC system. 
  • Many older homes have vented crawl spaces which allow moisture and pests to enter freely. This can lead to damage and mold and mildew growth which can be toxic for people in your home. It’s important to seal any open crawl space vents with durable, airtight covers to prevent this from happening.  

Mistakes to Avoid When Repairing Your Crawl Space 

  • Having a sump pump installed in your home is a great step towards protecting it from water damage such as a plumbing leak or flood. But, since these machines run off your home’s electricity, any power failure or device malfunction can render it useless. It’s important to install a battery-powered backup sump pump to ensure your home is still protected if something happens.  
  • Any waterproofing measures installed in your home is a step in the right direction to protect it from water damage. Although waterproofing solutions are important, fully encapsulating your crawl space will give you the ultimate peace of mind that your home doesn’t experience any moisture-related problems. Just installing a sump pump, or interior drainage system is not enough to fully combat water or mildew and mold growth.  
  • There are many home repair projects that get the green light to DIY, but crawl space repair and encapsulation isn’t one of them. As your crawl space is a very delicate part of your home, any mishaps could lead to further and costlier damage. Although many big box retail stores offer crawl space solutions, the products we offer at AquaGuard guarantee that your crawl space is protected with our long-term warranties.
