How to dehumidify a Garage?

How to dehumidify a garage:

We’ve dealt with a few damp garages recently.  These particular cases were caused by external floor drainage issues or from plumbing leaks in the colder weather.

A typical domestic garage, such as found attached to a detached or semi-detached house may be of concrete floor construction, with block or brick walls.  These walls may be covered with plasterboard or a different finishing sheet material.

  • Equipment used to dry a typical garage may be an industrial dehumidifier together with one or two industrial fans to circulate dry air around all of the floor. In addition, we find garages often are unheated therefore it may be necessary to add a portable heater in order to boost the temperature and enhance the performance of the dehumidifier.
  • Drying environment required for a garage, as best with all rooms, is as closed-air as possible. If a garage has a barn or up-and-over type door, attention should be paid to possible air gaps that let in too much air from outside.  It may be necessary to sheet/tape over these gaps in order to close off the outside air as best as possible.
  • Floor preparation would mainly be removal of any floor coverings that may be restricting the evaporation of moisture out of the concrete, particularly removing linoleum floor covering if present.
  • Wall preparation may be required if surface finishes are affected by water damage. Plasterboard wall finish for example may need to be cut away in order to expose the structural material behind.
  • Drying time for dense materials such as concrete and brick/concrete block could be around 4 weeks depending on degree of saturation.
  • Disinfecting/cleaning may be required particularly for flooding from a drainage issue, in order to decontaminate and help reduce the likelihood of any adverse health affects taking hold in the property.
