"Josue met with me 3x during the bid process to help me come up with a plan to address all of my specific water issues. He really cared about meeting my needs. His crew was great, too. They were warm and friendly, showed up on time every day, completed the work timely, and cleaned up promptly. I felt they really cared about my property and my satisfaction. They did a great job and were worth every penny. I highly recommend this company!"

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

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.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
