Q: Can a damp basement affect upstairs?

• <div><p>Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement. </p></div>

Q: Can you make a crawl space liveable?

• <div><p>Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable. </p></div>

Q: Can you finish a basement with no windows?

• <div><p>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.</p></div>

"They completed it in 2 days and I havent had an issue since the basement was waterproofed. However, they did forget to plan the initial inspection prior to the work as part of the permit. The city I live in ended up reaching out near the end of the permit date and I didnt know about it until then. I reached out to the project manager for my project at Acculevel about it and they did handle that issue promptly."
