Job Stories From Block Island, RI
Block Island, RI Dehumidification

Robin called DryZone because her second home in Block Island, RI was having some humidity issues in the basement and she wanted to be able to use the space without worrying about her belongings getting damaged or moldy. She had seen our trucks while we went to the island to do services and wanted to get on our radar for the next time we were there for a free estimate.

At the estimate, James used his trusty hygrometer to read the humidity in the basement and saw it was reading a shocking 80%! He let Robin know that was very high and he seriously recommended a SaniDry dehumidifier to help get that to a reasonable level. After some discussion about the details of the system, she knew she wanted that in her home and wanted to go through with installing the system. A great part of the SaniDrys is that they are self-draining systems and could empty right into her pump without someone needing to be there to empty it each day.
