Moisture is the root cause behind most crawl space problems. Ground water and humidity rise into the space, feeding mold, rotting structural wood, attracting pests, and pushing damp, musty air up into your living areas.
Cube Restoration builds a complete moisture control system tailored to your home — vapor barriers, sealing, drainage, sump pumps, and dehumidification — so the crawl space stays dry and your foundation stays protected for the long haul.
Controlling moisture at the source does more than prevent damage. It improves your indoor air, helps your HVAC run more efficiently, and protects the value of your home.
What’s Included
Vapor Barrier Installation
Blocks ground moisture from rising into the crawl space.
Crawl Space Encapsulation

Problems Caused by Crawl Space Moisture
Left unchecked, a damp crawl space causes problems that reach well beyond the space itself:
Mold & Mildew
Damp conditions that feed growth and harm indoor air quality.
Wood Rot
Moisture weakening joists, beams, and subfloor over time.
Pest Attraction
Damp, dark spaces that draw rodents and insects.
Poor Indoor Air
Musty, humid air rising into your living areas.
Higher Energy Bills
Humidity that makes your HVAC work harder.
Lost Property Value
Structural and moisture issues that hurt resale.

Moisture Control FAQs
Usually a mix of ground humidity rising through bare soil, poor drainage around the foundation, and unsealed vents and gaps.
Often both work together — the barrier blocks ground moisture while the dehumidifier manages the humidity already in the air.
Controlling moisture removes what mold needs to grow, which is the most reliable way to prevent it from returning.
Musty odors, visible mold, standing water, or condensation in the crawl space all point to a moisture problem worth addressing.
Often, yes — drier air is easier for your HVAC to condition, which can reduce energy use.
Yes — we can check and service your system over time to keep it working as it should.
