Questions

Common questions.

Does Black Rock flood?

Yes. In April 2025 the Black River was expected to crest at 30 feet, one foot shy of the record, and in May 2017 a shelter for flood evacuees opened at the old Black Rock School cafeteria.

Why is mold such a concern in Arkansas homes?

Arkansas has hot, humid summers. NOAA's 1991-2020 normals put Little Rock's average yearly precipitation at about 50 inches and its July average temperature at about 81 F. EPA advises keeping indoor humidity below 60 percent, ideally 30 to 50 percent. Warm, damp air is why moisture problems show up in Arkansas attics, crawlspaces and bathrooms.

Why do crawlspaces matter in Arkansas houses?

EPA notes that crawl spaces with high humidity are common sites of hidden mold growth, especially over bare soil, and that soil moisture raises the humidity in the air above it. Arkansas summers are humid, so crawlspace moisture is a common thing buyers ask about. EPA also advises grading the ground away from the foundation so it does not stay wet.
