Most of the time the origin of musty smells in a home is the basement or crawl space (subfloor)
In most cases subfloor ventilation is what is used to control the humidity in a basement or subfloor, in some cases though a ventilation system is not enough, this could be in cases such as really damp spaces due to lateral moisture ingress, groundwater seepage or in a climate where the natural outdoor environment has extended periods of high humidity.
In these cases Zenith Ventilation can install a dehumidifier for the basement, this would ensure that the humidity levels remain at the desired levels to prevent all of the things that high humidity causes such as mould, musty smells, timber or, termites etc
We strategically select a dehumidifier from our quality dehumidifier suppliers for each basement
