I hired them to bat-proof my attics, clean up all the debris, and put down new insulation. From start to finish, they were professional, thorough, and respectful of my home. Dan Jones, the salesperson, really stood out—he actually took the time to get up into the attics himself before making any recommendations or giving an estimate. That attention to detail gave me a lot of confidence in moving forward. The crew, led by Roberto, did an excellent job. They worked efficiently, explained what they were doing along the way, and left everything cleaner and more secure than before.

Moisture barrier encapsulation is the process of sealing off areas—like crawl spaces or basements—with a moisture-resistant barrier (usually heavy-duty plastic sheeting or vapor barriers) to prevent water and vapor intrusion. This creates a controlled environment, reducing the risk of moisture-related issues.
Moisture barrier encapsulation is important because it:
Prevents mold, mildew, and wood rot caused by excess moisture
Protects your home’s structural integrity
Improves indoor air quality by limiting the spread of allergens
Enhances energy efficiency by reducing humidity and HVAC load
Encapsulation is typically installed in:
Crawl spaces
Basements
Under floors in homes built over damp or poorly ventilated ground
These areas are most vulnerable to moisture infiltration from the ground.
Common materials used in encapsulation include:
Heavy-duty polyethylene vapor barriers (6 to 20 mil thickness)
Seam and edge sealing tape
Mechanical fasteners or anchors
Spray foam or rigid foam insulation (optional)
Dehumidifiers for climate control
Drainage systems such as sump pumps or French drains, if needed
