The air you breathe and the floors you walk on both depend on what’s happening under your feet. We take you beneath the house to reveal the three real reasons homeowners choose crawl space encapsulation: healthier indoor air, a stronger structure, and smoother real estate transactions. Along the way, we cut through common myths, explain why quick patches often backfire, and share the steps that turn a damp, musty spac...
Cold air can fool you. A basement can feel crisp at 60 degrees while humidity sneaks past 70% and turns prized gear into mold bait. We bring on Alex Hamilton from Aprilaire to demystify why HVAC systems are built to control temperature, not moisture, and how that gap leads to musty smells, surface mold, and ruined finishes in basements and crawl spaces.

When homes are buil...
Neglect is the silent killer of home mechanical systems. Michael Church and Stephen Malpass dive deep into a shocking discovery at a beach house where a never-maintained dehumidifier had developed what professionals call "zooglea" - a foul-smelling bacterial growth that resembles "the jelly from a Costco chicken bag, but four times nastier."
