Causes Of Dampness In Your Basement

Dampness and mold growth in basements is a common problem but unfortunately is one that is often misunderstood and not treated in the right way. The first thing you need to do is work out why your basement is damp – where is the water coming from? If it is something as simple as a leak or a blown seal in double glazing, then sometimes a quick repair is all you need.


But for most homes excess humidity in a basement is as a result of either humid air coming into the basement and condensing in the cooler atmosphere or on cold surfaces like metal or too much moisture internally from wet clothes, cooking or even bathrooms.

What To Look For

Once you know what is causing your excess humidity, you can start looking for the best dehumidifier for basement mold. A humidity level above 50% is generally a sign you need to reduce the moisture.

Choosing The Right Dehumidifier For Your Basement

So what do you need to look for when you’re searching for the best basement dehumidifier? There are so many makes and models out there that all have different settings, capacities and claims. Basement dehumidifier reviews can be confusing, so here are a few things to bear in mind when you are looking for a new unit.

Assess Your Room

The most important thing to do when you are buying a dehumidifier for your basement is look at the temperature of the room. A lot of people don’t realise that most dehumidifiers are only capable of working at 65 degrees or above. Any lower than that, and you risk the metal coils of the dehumidifier icing up as the water hits them which will stop your unit working.

There are specific low-temperature dehumidifiers which work well in basements. Check the top temperature the dehumidifier can work well at and compare it to the temperature in your room.


Capacity is one of the easiest things to work out. Look at the size of your basement and then calculate how much capacity and power your dehumidifier will need. Dehumidifiers are rated by their pint capacity per day and you should choose a unit with a higher capacity if you have a large basement. Using a hygrometer, a tool that measures air temperature and humidity, will give you a good idea of how humid your room is as well as telling you what the current temperature is.


Knowing the size of your room in cubic feet is also useful. This will tell you how much air in the room you need to dehumidify. Read here for more information on sizing.


Added extras, some top quality models of dehumidifiers come with digital humidity readout with a 24-hour timer and control lock. This makes it even easier to control the level of humidity in your room and adjust it as you need to the recommended basement dehumidifier setting.

As energy prices get more and more expensive, looking at how efficient your basement dehumidifier is also important. Most good units come with an energy efficiency rating and to get the best energy efficient basement dehumidifier you should judge the rating against the Energy Star website.

Getting The Most From Your Basement Dehumidifier

When deciding what the best dehumidifier for the basement will be, look at where you can put it. If you are looking for a fixed unit it will need to be mounted on a wall and be near a drain so the hose can take water directly outside. The air intake vent on your dehumidifier should be at least six inches from any wall so air can flow into it freely.


For portable units, make sure you’ve got a clear space as near to the centre of the room as you can. This will make sure the dehumidifier is working to clear your entire room.

Other Things You Can Do

As mentioned above, fixing problems in your home like leaking windows or clogged gutters, can also help to reduce the humidity in your basement. By tackling these small tasks and making your basement more watertight you will reduce the work a dehumidifier has to do and make it work more efficiently – drying out your home quicker.


Dehumidifiers can be noisy but in a basement this isn’t usually a problem as most spaces are used for storage or laundry. But if you are converting your basement into somewhere you will spend time, such as a workshop or lounge area, it is worth making sure you pick a unit with a lower noise output.
