What is Crawl Space Encapsulation?

Crawl space encapsulation is a green, environmentally sensible solution, helping you and the planet at the same time. It is the process of preventing moisture from entering the crawl space either from the dirt below or from the outside. This process then closes the vents and completely seals it ensuring a clean environment. A seven-layer barrier, installed over walls and floor, prevents mold and bacteria growth. The white covering makes the area brighter, cleaner, and healthier.

Together with crawl space insulation and vapor barrier installation, crawl space encapsulation has continuously become popular in the past few years. Many people are turning to the realization that taking care of such spaces has more than one benefit, despite the installation costs that might be involved. To respond to this new realization, the maintenance, and repair industry has continued to grow by leaps and bounds to ensure that this service is occurring more frequently.

Crawl Space Moisture

The crawl space of your home is often a neglected area of concern, yet moisture buildup, mold and bacteria growth, and mustiness are all very real problems affecting the health and energy efficiency of the house. If you see any drywall cracks or unevenness on the floor of your crawl space (or any basement with a dirty floor) or smell any musty or foul odors, you may need some repair work such as crawl space encapsulation. If you have heightened allergy or asthma symptoms during the warm weather season, you could probably benefit from a sealed crawl space solution.

Furthermore, homes with crawl spaces are very similar to homes with a basement, but with one major difference – the floor is dirt. As if a home had a dirt floor basement, wet crawl spaces can cause odors and serious health issues.

Compared to professional foundation and waterproofing contractors, homeowners are not experienced when it comes to crawl space moisture problems and taking preventative measures to properly waterproof the area. Unfortunately, the effects of dampness and moisture can damage your health, crawl space, above ground living areas and your home's overall structure.

Most homeowners are inexperienced and believe that doors, windows, and vents are responsible for all moisture problems in your home, but that isn't always the case. Factors such as humidity, moisture, and wetness in your crawl space are the source and can cause structural problems.

Moisture Causes Structural Integrity

Are you having questions or concerns about the structural integrity of your home due to moisture? If you fall into this category, do not fear. In fact, routine examinations can protect your home from structural problems. Below are some signs to look for:

  • Uneven floor
  • Warped floors
  • Cracks in interior walls
  • Damaged floor joists

Uneven floors, caused by moisture in your crawl space, are very common problems among homes. If you believe these describe your situation, make sure to take action immediately with a professional foundation contractor. It’s more cost-friendly to make small repairs than to wait and be forced to replace an entire foundation.

Mold and Mildew

There are several different forms of mold that can quickly invade all living areas. A majority of the time when a home is occupied with bad smells and odors, it is a sure sign your crawl space has a hidden problem with mold.

A damp environment is perfect for wild animals, insects, and pests to thrive making for some extremely unhealthy and destructive conditions. A crawl space that isn’t sealed and protected against moisture can develop mold and mildew issues. Black mold and dry rot can even develop!


Simply put, the best and most effective way to rid your home and crawl space of bad smells and odors is to schedule an appointment with a waterproofing or foundation expert. It is also a good idea to perform routine inspections looking for mold, dry rot or damaged wood. By taking measures to protect your home and crawl space from these elements, you will protect your family’s health. A waterproofing expert will identify the source of the water intrusion. Then provide the necessary repairs and seal the crawl space.

Crawl Space Encapsulation

The best and most effective way to protect your home from moisture, structural weakening, bad smells, and odors is to contact a professional crawl space contractor. A professional foundation contractor will complete an on-site inspection, provide professional consultation, provide a free estimate and recommend the best and most cost-efficient way to solve the problem. Whether it requires a full crawl space encapsulation or a simple drainage system you need a solution now.
