How long will I need the dehumidifier for?

27th Apr 2015 | |

It sounds obvious but this depends on what is wet and how wet it is. On delivery of drying equipment we can offer some free advice on this. If requested, we can also undertake moisture sampling throughout the drying process to monitor progress.

For rooms with humidity issues, and for general use such as mitigating mould, we would recommend running a dehumidifier on a schedule, eg 6-12 hours per day. Keeping the humidity at 30 – 60% reflects an adequately dry atmosphere and will help reduce the likelihood of mould and other humidity damage.

More intense use is required for drying water damaged building materails after a leak or flood. We would generally find that with equipment running constantly, lightweight materials such as single-sheet plasterboard (eg ceilings and stud walls) can dry in a week or so, however dense materails such as bricks and concrete take considerably longer.

Flood and water damage drying often is best undertaken with preparation work such as removal of floor coverings to expose strctural floor; removal of plaster from solid walls; opening of stud walls where wet insulation may be within. This removal of water damaged materials will quickly remove water from the building, then allow more direct exposure of structrual materials to dry air from the dehumidifiers.

Do please send us a photo of your flood/water damage with an explanation and we can come back to you with some advice.
