Why Choose Crawl Space Encapsulation?

Your home may be more affected by its crawl space than you realize. Up to 50% of the air in your home can originate from the crawl space. This contamination of mold and black mold spores can severely threaten your family’s health.

Crawl space encapsulation is the solution. It prevents moisture from seeping in and significantly improves indoor air quality. The process typically involves installing a dehumidifier to maintain low moisture levels and sealing off all seams with plastic.

Crawl space encapsulation is crucial for those living in humid regions near bodies of water. Increased moisture in the soil around your home and higher humidity create ideal mold and mildew growth conditions in enclosed, dark crawl spaces.

When to Consider Crawl Space Encapsulation?

It’s time to consult our crawl space encapsulation experts if you notice any of these signs:

  • Presence of mold or mildew in your home.
  • A musty mildew smell indoors.
  • Rising heating and cooling costs.
  • Damp insulation.
  • Windows that appear to sweat.
  • Pest infestations.

Benefits of Crawl Space Encapsulation

Here are the various advantages of opting for complete crawl space encapsulation in your home:

1. Improved Air Quality: Proper crawl space encapsulation promotes clean air circulation throughout your home, creating a healthier environment for your family and guests. Encapsulated crawl spaces prevent moisture growth, ensuring that humid air isn’t circulated throughout your home.
2. Pest Prevention: Insects like termites thrive on moisture. Encapsulating your crawl space eliminates conditions that attract pests, protecting your home from infestations and the damage they can cause.
3. Enhanced Quality of Life: A healthy home is essential for well-being. Enclosing your crawl space eliminates moisture issues, preventing mold and mildew problems that can lead to health concerns.
4. Structural Integrity: Keeping moisture out of your crawl space is vital for the long-term stability of your home’s foundation. By protecting this area, you also safeguard the soil surrounding your house’s foundation.

Annette Casatelli

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.

Ellen Szuchmacher

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.
