Why do basements take longer to dry?

Sub-grade spaces stay cooler and the surrounding soil holds moisture against the walls. Cool air holds less moisture than warm air, so dehumidifiers work harder for less yield. We use LGR dehumidifiers built for low-grain conditions and supplement with heat where it makes sense.

Will the foundation crack be a problem long-term?

If the cause was groundwater intrusion through cracks, the foundation needs to be evaluated by a structural professional and waterproofed before the rebuild. Drying alone won't stop the next storm. We coordinate with foundation repair and waterproofing partners.
