What happens in the crawl space doesn't stay there. A large share of the air on your main floor rises from below, so a damp, dirty, or poorly insulated crawl space means cold floors, higher energy bills, and worse indoor air upstairs.
Cube Restoration cleans out the debris, removes damp or damaged insulation, seals the gaps that let outside air and moisture in, and installs insulation that keeps your floors warm and your foundation protected.
We also handle the moisture side of the job — vapor barriers, encapsulation prep, and dehumidification — so your new insulation stays dry and effective instead of becoming a magnet for mold.

Crawl Space Insulation FAQs
Much of the air on your first floor rises from the crawl space, so its condition affects your comfort, energy bills, and indoor air quality.
Yes. Wet or moldy insulation loses its effectiveness and can affect air quality, so we remove it and address the moisture source.
Usually, yes. Insulating and air sealing the crawl space is one of the most effective fixes for persistently cold floors.
In most cases, yes — insulation alone won't last in a damp crawl space, so a vapor barrier keeps it dry and effective.
Yes — it dampens sound transfer along with improving comfort and energy efficiency.
Most crawl spaces are completed in a day or two, depending on size, cleanup, and any moisture work needed.
