Job completed for How We Turned a Damp Crawlspace into a Dry, Sealed Space

Completion date: June 6, 2025

Location: Harvest, AL

Why did the customer contact us?

A homeowner reached out to us after noticing musty odors and rising energy bills, and he suspected the insulation in his crawlspace had failed. When we talked through what he’d been seeing—uneven floors above, damp air, and insulation hanging down in spots—it became clear the existing fiberglass had been compromised by moisture and air movement. He wanted a lasting fix, not a quick patch, so we scheduled a crawlspace evaluation to confirm what was going on and outline the best way to remove the damaged material and replace it with insulation that would actually perform in that environment.

Solutions provided:

After our inspection confirmed the insulation had been damaged by ongoing moisture and uncontrolled air exchange, we tackled the crawlspace as a complete system instead of just swapping material. We started with full insulation removal to eliminate the wet, sagging fiberglass and any trapped contaminants. Next, we installed a partial-perimeter drainage pipe to intercept water at the foundation and direct it to a new 1/3 HP sump pump, then routed the discharge line safely away from the home so water couldn’t cycle back into the crawlspace. To stop outside humidity from constantly feeding the problem, we blocked the foundation vents and sealed the ground with a durable 9 mil vapor barrier. From there, we added a Sierra Watchdog NXT 85-pint dehumidifier to maintain consistent, dry conditions year-round. Finally, we finished the enclosure with a custom-built PVC crawlspace door for a tighter, longer-lasting seal—creating a clean, dry crawlspace where new insulation and the home above can actually perform the way they should.
