How to Remove Damp and Mold From a Garage


The garage is one of the most important rooms in every homestead. It is the home to your car(s), where you store your power tools, and serves as a workshop when you need to do various chores.

However, it is one of those areas that people neglect a lot, and they tend to focus much on the lawn, driveway, and the home garden.

Like any other rooms in the house, the garage can accumulate moisture and humidity that leads to unwelcome mold growth on wood rafters, concrete, drywall, and metal shelving

There are many risks associated with mold growth. Mold spores can cause asthma, pneumonia, and other health complications if not taken off immediately.

Molds also produce mycotoxins that may find their way into the main house. The good news is that having molds and dampness in your garage is not a death sentence.

Let us explore different approaches to prevent and get rid of these challenges:

Inspect your garage

A thorough inspection of your garage will indicate the areas that are likely to attract mold build-up. Some of the areas of focus should be the drainpipes and the gutters.

Ensure that there are no leakages in the garage. Water spillage can cause serious damages to your valuables.

Another focus area should be the windows and the roof. Ensure that water does not sip through any of the openings and find its way to the garage.

If you have a solid garage structure with a proper drainage system and lacks cracks, then mold will never be a challenge to you.

Keep the garage organised

This is the place where you will keep most of the stuff that you do not use frequently. You need to ensure that this place is organised and get rid of anything that may lead to mold build-up.

Have some shelves where you can store your stuff instead of dumping them on the floor. Some garages are prone to flooding or leaking water challenges.

Storing your stuff in a raised area prevents them from dampness if this happens.

Ventilate your garage

Molds and dampness thrive in dark and stuff environments. Ensure that your garage has enough natural light and good ventilation.

You can install extractor fans that will keep the air clean and fresh. The idea behind this is to keep the air in your garage dry, warm, and circulating, making it hard for mold to build up.

If you are working on a project, you can leave the garage door open for a few hours during the dry, warm, and sunny days. Avoiding leaving wet clothes or shoes in the garage as they increase humidity levels.

Keep humidity in check

There are many tools that you can use to keep humidity in check. A dehumidifier is a portable device that decreases dampness in a room after pulling moisture from the air.

The ideal humidity in a home should be between 30 and 60%. It is this relative humidity that lowers the chances of illness and also increases comfort in your home.

The normal dehumidifiers may not be that effective when it comes to fighting molds in a garage. The good news is that you can bank top rated desiccant dehumidifiers for this task.

A desiccant dehumidifier has a rotating desiccant wheel where silica gel absorbs moisture in the air.

The wheel then retains about 25% of the air as ‘reactivation air’ while the rest 75% is released back into the room as processed-dry air.

Such a unit heats the air at high temperatures between 90 and 140 degrees Celsius, which drives the moisture out of the silica gel.

Clean your garage

You do not have to wait until molds build-up to start working on your garage. However, when this happens, you can still salvage the situation with a thorough cleaning exercise.

Scrubbing is the best approach to contain mold from spreading.

Spray the affected area with warm water to prevent mold spores from spreading as you clean. You can then use a commercial cleaner that is designed to neutralize molds or bleach.

Some of the most effective bleach options are hydrogen peroxide or white vinegar; however, you should never mix the two.

Let the cleaning agent sit briefly on the affected area and then scrub with a brush. Rinse with clean water and repeat the process if you can still see traces of mold.

Dry the affected area after you have successfully scrubbed and removed the mold. Your garage should be well-ventilated when using bleach as your cleaning agent.

Keep the surrounding clear

The presence of stagnant water and overgrown bushes near your garage could be the reason for the dampness. Drain the stagnant water pools near your garage and reduce the chances of the water getting to your garage.

If you are like most people hiding their garages behind trees, you are setting yourself up for trouble. Plants that are too close to the garage can cause cracks in the wall and eventually allow moisture into the garage.

The roots are also likely to penetrate the garage structure and eventually create an excellent environment for molds to grow.

Involve an expert


If you follow are the above steps, and you still can’t get rid of the mold, then it is time that you involve an expert. Such an expert will assess the situation and even alert you of any mold that you cannot see.

Such people are trained to work with various tools and chemicals that are handy in mold removal process.

You will note that these experts have different mold removal approaches for different parts of your garage, such as the roof, walls, door, and wooden parts.

Follow their advice on how to keep your garage mold-free once they are done with the exercise.

Preventing and removing mold from your garage is easy when you follow the above tips. Ensure that you inspect your garage regularly and know when to involve an expert on the same.

Have a cleaning schedule that will deal with the basic dirt but also have a professional cleaning experience regularly.
