Q: Is a pier and beam the same as a crawl space?

• <div><p>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 &ldquo;crawl space foundations,&rdquo; but the crawl space itself is separate from the foundation. </p></div>

Q: What preventative measures can reduce the risk of future water or storm damage?

Q: When should you not finish a basement?

• <div><p>Basements with persistent moisture problems or flooding shouldn&rsquo;t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. </p></div>

Q: Where should I avoid using a dehumidifier?

• <div><p>One handy thing about whole-house dehumidifiers is, once installed, you don&rsquo;t have to worry about placement or changing the dehumidifier&rsquo;s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.</p></div>

Jeff is an amazing craftsman. We have a 127-year-old house. We don’t think any real work has ever been done to the foundation. He came in when we had a big leak after a snowfall. His solution was innovative and effective. We ended up using it throughout the basement! Great work, Jeff!

Basement Waterproofing questions, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

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.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
