Crawl spaces are one of the most overlooked areas of a multifamily building. Yet the moisture, debris, pests and mold that build up below the floor can affect odors, air quality, floors and even the structure of the units above.
Regular crawl space cleaning and moisture control protect the units above. As the EPA explains in its guide to mold and moisture, the key to mold control is moisture control.
Most newer Florida buildings sit on concrete slabs, but many older buildings, raised structures and some garden-style communities have crawl spaces that need regular attention.
Why Crawl Spaces Matter in Multifamily Buildings
- Air quality. Air from the crawl space can move up into living spaces, carrying odors and moisture with it.
- Moisture and wood rot. Damp framing and subfloors weaken over time.
- Pests. Termites, rodents and insects thrive in dark, damp spaces.
- Hidden leaks. Plumbing leaks and duct condensation below the floor often go unnoticed.
- Insulation. Wet or fallen insulation stops insulating and holds moisture against the structure.
Florida Crawl Space Challenges
Heat, humidity and heavy rain make moisture control the biggest challenge in Florida. The EPA recommends keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent, to limit mold growth, and a damp crawl space makes that harder for the units above. Florida is also home to subterranean termites, so wood debris and moisture under a building deserve prompt attention.
Warning Signs Your Crawl Space Needs Cleaning
- Musty odors in ground-floor units.
- High humidity or condensation in the units above.
- Soft, sagging or uneven floors.
- Standing water or damp soil after rain.
- Signs of rodents, termites or other pests.
- Insulation hanging down or lying on the ground.
- Debris, trash or old materials left from past repairs.

What Professional Crawl Space Cleaning Includes
- Inspection with photos of moisture, pests, plumbing, ducts, insulation and structure.
- Debris removal, including trash and old construction materials.
- Removal of wet or damaged insulation.
- Cleaning and sanitizing of affected surfaces.
- Clearing blocked vents and checking drainage around the building.
- Reporting leaks, wood damage or pest activity so repairs can be scheduled.
- Documentation of every visit. At AMB Services, reports and photos are available in the AMB App.
A note on mold: in Florida, mold assessment and mold remediation of areas larger than 10 square feet must be performed by professionals licensed by the Department of Business and Professional Regulation. If significant mold is found, bring in licensed specialists before cleaning continues.
How to Keep Crawl Spaces Clean and Dry
- Keep gutters, downspouts and grading directing water away from the foundation.
- Repair plumbing and AC condensate leaks quickly. Learn the warning signs in our pipe repair guide.
- Install or repair a vapor barrier over exposed soil.
- Keep crawl space vents clear and screened against pests.
- Consider encapsulation or dehumidification for chronically damp spaces.
- Inspect at least once a year and after major storms as part of your preventive maintenance program.

Frequently Asked Questions
How often should a crawl space be inspected?
At least once a year and after major storms or flooding, and more often in buildings with a history of moisture, plumbing or pest problems.
Can a dirty crawl space affect the units above?
Yes. Moisture, mold and pests below the floor can affect odors, humidity and indoor air quality in the units above, which is why crawl spaces should be kept clean and dry.
What is crawl space encapsulation?
Encapsulation seals the crawl space with a heavy vapor barrier on the ground and walls, often combined with a dehumidifier, to keep moisture out. It is usually considered for chronically damp crawl spaces after cleaning and repairs.
Does AMB Services clean crawl spaces in Florida?
Yes. AMB Services is based in Davie, Florida and cleans and inspects crawl spaces for apartment communities and condominiums in Broward, Palm Beach and Miami-Dade counties and throughout Florida.
