If you’ve noticed a damp feeling in the house, moldy closets, or musty odors, you probably have crawl space moisture. Up to half of the air in your house can come into the house from the crawl space due to the Stack Effect.
Stack Effect – aka the chimney effect – as warm air rises it pulls the air upward and creations a suction, whereby sucking air from the lower extremities of the house, including the crawl space, floor vents, doors, windows or other minor openings.
Once you have high moisture, a crawl space dehumidifier might be necessary. In Virginia and North Carolina, we have warm humid summers with high outside humidity, making for wet crawl spaces and fertile grounds for mold growth. By installing a crawl space dehumidifier, you’re protecting your crawl space from high moisture and mold growth. For a free crawl space dehumidifier installation quote, click here.
There are over 20+ distinctions you need to get right in order to properly install a dehumidifier. Our recommendation is ALWAYS, Trust the Experts. Get it done right, the first time.
If you hire a handyman vs. hiring a professional contractor, you’re risking an incomplete and ineffective result that is really important to achieve, the first time. You don’t want to assume everything is working, when it’s really not, because most people don’t regularly check their crawl spaces.

The price for a Santa Fe Compact 2 dehumidifier (most popular) sells for $1,118.99 at Sylvane.com. This unit was the replacement for the Santa Fe Compact 2 dehumidifier with new branding.
The price for a Santa Fe Advance90 dehumidifier (2 fans) sells for $1379.99 while the Advance100 sells for $1798.99 on the Sylvane website. These units are great for big crawl spaces that benefits from it’s ‘Dual Fan’ feature. It dispenses dry air in multiple directions.
The price for a Santa Fe Classic dehumidifier (basement) sells for $1,699.99. For large basements, we recommend this unit as the best basement dehumidifier available. It has a large capacity to control moisture in your wet basement. It is a standup unit, not applicable for crawl spaces because of it’s 36” height.
We have also installed over 1,000 Santa Fe brand crawl space dehumidifiers. We don’t have many problems with these units but we switched to Aprilaire for the superior technology and warranty. The warranty for the Santa Fe compact dehumidifier (most common unit) is only 1 year on parts and labor, with a limited 5 year warranty. This warranty isn’t great.
The best thing about the Santa Fe crawl space dehumidifier is it’s super easy operation. The controls for the dehumidifier are simple. Set the dehumidifier to ‘Fan Auto’ and change the dial to ‘Normal / Dry’ and your crawl space should dry up IF it is properly sealed.
