"Dean and his crew were professional, reliable, extremely neat/clean and went above and beyond, often, to make the sure work was completed to my satisfaction. They did small things not even required to make sure the entire basement area was much more than even expected. The basement has never been so dry in the 40 years I have lived here. I would hire them again in a heartbeat."

Basement Waterproofing questions, answered by experts

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

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.
