"The crew was absolutely amazing! Very impressed with how professional, polite, and personable they all were. The management and crews are top notch! Management answered all the questions I had, walked me through what steps they were going to take to get things done. Dustin was extremely thorough, knowledgable, and took time to explain the recommended systems. I will 100% be utilizing them in the future strictly based on the level of trust and quality he presented! His communication was fantastic, they always arrived on time. They were careful with the property, always cleaned up when they were done. I will absolutely hire them again to complete any future foundation/basement work and I will absolutely recommend this company without reservation or hesitation. They stand behind their work."

Basement Waterproofing questions, answered by experts

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.
