Ready to tackle the critical but often overlooked step in crawl space renovation? In week three of our Crawl Space Repair Challenge, we're diving deep into the proper installation of dehumidifiers and condensate pumps—essential components for creating a dry, healthy environment beneath your home.
Moisture control is the cornerstone of crawl space remediation, and this comprehensive guide walks you through everything from selecting the right commercial-grade equipment to determining optimal placement for maximum efficiency. I'm sharing professional insights on humidity targets (aim for 45-55%), wood moisture levels (9-15% is ideal), and how to interpret often misleading dehumidifier specifications. You'll discover why you can't actually "oversize" a dehumidifier and how larger units can save you money through improved efficiency.
For homeowners with larger or compartmentalized crawl spaces, I explain effective air circulation strategies using supplemental fans. We also explore various water discharge options suitable for different climate conditions, from simple exterior drainage to specialized dry wells below the frost line. Whether you're a DIY enthusiast or just want to understand what professionals should be doing in your crawl space, this episode provides the knowledge you need to make informed decisions about moisture control.
