If you have a vented crawlspace and are having issues with humidity, a Smartvent Ventilation system could be the answer to your troubles.

Crawlspace ventilation is still a controversial subject among building scientists because allowing air to flow around non-insulated water pipes, HVAC ducts, and exposed wood floor joists can lead to moisture issues and mold. But an unvented crawlspace could produce the same results if trapped air is moister than the air outside.

The Smartvent Ventilation System solves the dilemma by offering a compromise solution. The system’s onboard computer monitors the interior and exterior air and provides ventilation when the air outside is drier than the air inside the crawlspace.

Costing less than $400, the Smartvent System can be installed in about an hour, depending on the conditions of the crawlspace.

It is secured in place with mortar, very similar to the installation technique for metal, louvered vents, and is conveniently designed to be slightly smaller than the size of a typical cinderblock.

The vent is installed in the same manner as any other foundation vent and is cemented or caulked (with long-life, clear outdoor caulk) in place prior to making electrical connections.

The system, which comes with a cord and plug, requires a standard electrical receptacle and the unit has a 40-watt draw but is only activated when ventilation is required.
