01
Dry It
4–6 weeks with a dehumidifier
Mold regrows anywhere humidity climbs above 60%. We install a dehumidifier first and let the crawl space dry for four to six weeks — the step most contractors skip.

The Raleigh Ninja Standard
Dry It. Remove It. Seal It.
A crawl space isn't fixed by spraying something on the mold and calling it done. Here's exactly how we do it — the same order, every project.
02
Remove It
Soda blasting at 150 psi
We physically remove visible mold by soda blasting with non-hazardous Arm & Hammer baking soda. The EPA calls for removal — not just spraying a chemical over the surface.
03
Seal It
Vapor barrier + conditioned air
A sealed vapor barrier goes across the floor, walls, and piers. A dehumidifier and exhaust fan hold negative pressure so moisture and radon stay out of the living space above.

FAQs
Crawl space questions, answered.
The questions Triangle homeowners ask us most often about mold, moisture, encapsulation, drainage, and dehumidifiers.
How do I know if my Triangle NC crawl space has a moisture problem?
The everyday signs are a musty smell on the first floor, cupped or springy hardwoods, condensation on ductwork, rusting metal supports, and higher-than-expected humidity readings in the house. In the Triangle, our summer dew points sit in the 70s for weeks at a time, which pushes most vented crawl spaces above 70% relative humidity. If you haven't looked under the house in a few years, a free assessment tells you where you actually stand.
What does professional crawl space mold remediation actually involve?
Three steps, always in this order. We dry the space with a properly sized dehumidifier for four to six weeks so the wood and soil are no longer feeding mold. We physically remove the mold by soda blasting with Arm & Hammer baking soda at 150 psi, then treat the wood with a hydrogen peroxide product. Finally we encapsulate and keep the humidity around 50% so the problem does not return. Follows EPA and IICRC published guidelines.
Why do you insist on a four to six week dry-out before remediation?
Mold regrows any time relative humidity climbs above roughly 60%. If we blast or spray a damp crawl space and seal it back up, the moisture trapped inside the wood keeps feeding new growth within months. Running a dehumidifier for four to six weeks pulls that bound water back out so the remediation actually holds. It is the step most competitors skip because it slows the schedule down.
What is crawl space encapsulation and what does the finished system include?
Encapsulation turns a vented dirt crawl space into a sealed, conditioned one. A heavy vapor barrier covers the floor, walls, and piers. Foundation vents are sealed. A right-sized dehumidifier holds humidity near 50% year-round, and an exhaust fan creates slight negative pressure so any leakage moves out of the house rather than up into it. The wrap by itself is not the system — the dehumidifier and airflow are what keep the space dry.
How does crawl space drainage work when there is standing water?
Standing water is a separate problem from humidity and has to be handled first. Depending on where the water is coming from we may regrade a small area, add an interior perimeter drain that catches groundwater at the footing, and pipe it to a sump pump with a sealed lid. Once the bulk water path is controlled, then the vapor barrier, dehumidifier, and encapsulation can do their job. Skipping the drainage step means the dehumidifier fights a losing battle.
