What is Crawl Space Encapsulation?

Your home might suffer more than you realize if constructed over a crawl space. Your crawl space may contribute up to 50% of the air in your house. Therefore, your family’s health may be in danger if that crawl area is contaminated with mildew and black mold spores.

Encapsulating the crawl area beneath your home prevents moisture from getting in and improves the air quality. This often entails installing a dehumidifier in the crawl space to maintain low moisture levels and covering the area in plastic to seal off all the seams.

But those who live in humid regions close to major bodies of water should pay particular attention to the importance of crawlspace encapsulation. Since more moisture may naturally exist in the earth around your home, and higher air humidity will facilitate the growth of mold and mildew in enclosed, dark spaces like a crawl space.

When to Get Crawl Space Encapsulation?

If you observe any of the signs below, it’s time to call the crawl space encapsulation experts:

  • Presence of mold or mildew in the home
  • A musty mildew smell inside the home
  • Increased home heating and cooling costs
  • Wet insulation
  • Windows that appear to sweat
  • Pest infestation in the home

Advantages of Crawl Space Encapsulation

Following are the various benefits of getting complete crawlspace encapsulation in your home.

Better Air Quality

Best crawl space encapsulation encourages clean air circulation throughout your house, making it better for your family and guests to breathe. Crawl areas that aren’t sealed allow moisture to grow. As a result, humid air is no longer circulated throughout your home after water is removed.

No Insect Infestation

Termites and other insects require moisture to survive. Encapsulating crawl spaces prevents the possibility of fostering conditions that attract pests like termites. By taking care of your crawl space needs with professional encapsulation, you can eliminate the risk of insect infestation, significant damage, and inconvenience pests cause.

Improvement of the Quality of Healthy Living

No one wants to get sick while they’re at home. However, a home is healthier for living and breathing when the crawl space is enclosed. Eliminating moisture from under your home will prevent mold, mildew problems, and other undesirable moisture problems.

Prevention of Structural Damage

It’s critical to keep moisture from building up in your crawl space for the long-term stability of your home’s foundation. When you keep water out of your crawl space, you also keep it out of the soil surrounding your house’s foundation.

I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.

They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.

Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.

Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
