Basement Waterproofing questions, answered by experts

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

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.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

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.
