Health and Structural Dangers of a Wet Crawl Space
When the air in your crawl space stays damp for too long, it doesn’t just smell bad. It quietly damages everything above it. The Environmental Protection Agency and the American Lung Association both recommend keeping indoor humidity between 30–50% relative humidity. Once it climbs past 60%, mold spores multiply, wood begins to rot, and your air quality declines fast.
On Long Island, that’s a real challenge. Coastal humidity, year-round groundwater flooding, and older home designs mean your crawl space stays moist even when it’s not raining. That hidden dampness can creep upward into your floors, insulation, and HVAC system.
- Promotes Mold And Mildew Growth On Joists And Insulation
- Damages Wood Flooring And Causes Cupping Or Warping
- Attracts Pests, Termites, And Other Moisture-Seeking Insects
- Reduces Indoor Air Quality, Triggering Allergies Or Asthma
- Increases Heating And Cooling Costs By Making Your System Work Harder
If left unchecked, humidity from below can shorten your home’s lifespan and threaten your family’s comfort. Don’t let your crawl space silently destroy your investment.

Case Study: Crawl Space Encapsulation and Mold Prevention in Carle Place, NY
The Problem:
A homeowner in Carle Place, NY reached out to Zavza Seal after noticing musty odors and soft flooring above their crawl space. Upon inspection, our team found standing moisture, failing insulation, and visible mold growth caused by poor ventilation and high humidity.
The Solution:
Our crew performed a full crawl space remediation: cleaning and disinfecting contaminated surfaces, applying antimicrobial treatment, and encapsulating the entire area with a vapor barrier. We sealed vents and perimeter gaps, insulated rim joists, and installed a Santa Fe Advance2 dehumidifier to maintain consistent humidity below 50%.
The Outcome:
Within days, the crawl space was completely dry. Humidity readings dropped from 78% to 45%, and the musty smell was gone. The homeowner reported improved indoor comfort and noticeably fresher air inside the home.

Frequently Asked Questions About Crawl Space Dehumidifier Installation in Long Island and New York
Why do crawl spaces in Long Island homes stay damp even in winter?
Long Island’s coastal climate and high groundwater levels keep crawl spaces moist all year. Even during colder months, humidity seeps through the soil and foundation walls, leading to condensation, wood rot, and mold growth if not properly controlled.
How does a crawl space dehumidifier improve indoor air quality?
About half of the air inside your home comes from the crawl space. A high-capacity dehumidifier like the Santa Fe Advance2 removes excess humidity and filters out dust, allergens, and mold spores. This helps keep the air in your living spaces cleaner, healthier, and more comfortable.
What’s the ideal humidity level for a crawl space?
The EPA and American Lung Association recommend keeping indoor humidity between 30 and 50 percent. Once it rises above 60 percent, mold and mildew begin to thrive. Santa Fe systems automatically maintain safe levels to prevent moisture-related damage.
Can a regular household dehumidifier work in a crawl space?
Not effectively. Store-bought units are not designed to handle cool or enclosed areas like crawl spaces. The Santa Fe Advance2 and Santa Fe Classic are engineered specifically for these conditions and continue removing moisture even when temperatures drop below 50 degrees.
Do I need both encapsulation and a dehumidifier?
Yes, they work best together. Encapsulation seals out moisture from the soil and outside air, while a dehumidifier regulates humidity inside the space. Combined, they keep the crawl space dry, improve air quality, and protect the structure year-round.
How often does a crawl space dehumidifier need maintenance?
Santa Fe systems are built for low maintenance. Filters should be replaced every three to six months, and a yearly inspection keeps the system running efficiently. Zavza Seal provides routine service and detailed inspection reports to ensure long-term performance.
Will installing a crawl space dehumidifier lower my energy bills?
Yes. When your crawl space air stays dry, your HVAC system doesn’t have to work as hard to heat or cool your home. This added efficiency can reduce energy use by 10 to 20 percent and extend the life of your equipment.
What size dehumidifier is best for my crawl space?
The right size depends on the size of your home and moisture levels. The Santa Fe Advance2 removes up to 90 pints of water per day for spaces up to 2,200 square feet. The Santa Fe Classic handles 110 pints per day and covers up to 2,500 square feet.
How long does professional installation take?
Most installations take just one day. Our team inspects your crawl space, sets up drainage and ducting if needed, and ensures proper airflow and humidity control. You’ll notice a difference in comfort and air quality almost immediately.
Why should I choose Zavza Seal for crawl space dehumidifier installation in New York?
Zavza Seal specializes in Long Island’s unique moisture conditions. Our certified technicians bring years of experience in crawl space encapsulation, waterproofing, and air quality control. We’re licensed, insured, and trusted across Suffolk and Nassau Counties for reliable, lasting results.
