There’s one place in a home that’s more prone to mould than any other; the garage. So this ‘how to remove mould’ is all about the dank and dingy garage. It’s often the forgotten space. We know a home needs proper ventilation to prevent black mould growth, but because of their big opening doors, garages are often left to look after themselves.
However, if you’re one of those people who park their car in the garage, then you’re just looking for trouble. Just think of wet or snowy weather, driving your car into the garage, and all that excess moisture you’re bringing in on the vehicle. With a warm engine and high humidity, you have everything you need to promote black mould growth.
How To Remove Mould From Your Garage Proven Tips To Stay Mould Free
All About Mould Dangers
Mould can be a pretty common problem, and unfortunately, a lot of people are unaware of the danger to self care untreated mould can cause. It can lead to some severe health problems.
- Other respiratory disorders
- Allergic reactions
- Migraine headaches
As we don’t spend much time in the garage on average, it’s safe to assume it’s likely to pose less of a risk than mould in the living spaces. However, if your garage is attached to the home, we need to be extra careful.
Garages are not airtight. We’ve been warned about running a car in the garage without adequate ventilation, as deadly carbon monoxide can seep into the home, the same can be said for mould spores.
The black mould spores and the harmful chemicals they produce are called mycotoxins and can quickly make their way from the garage into your home if you’re not careful and endanger your family.
How To Remove Mould from a Garage
The main problem when removing mould from anywhere in the home is stirring up the spores during the cleaning process. That’s why in more sensitive areas of the house it’s recommended to use professional mould removal experts to do the job.
However, black mould removal from a garage is less complicated and can be successfully achieved by a competent handyman or DIYer.
Important Things To Remember:
The critical point with black mould removal and the biggest headache is making sure all of it is removed. so it doesn’t have a chance to return. Mould spores are brought into the home on our clothing from the outside, and look to grow in dark areas, where there are warmth, humidity and little ventilation.
Apart from the health issues associated with mould, depending upon the construction of your home it can cause severe structural problems over time if not treated promptly. The mould fungi will spread in just a few days if you are not careful even if you’re using cleaning hacks.
How To Remove Mould From Wood
The first thing you must do when removing mould from the garage is to isolate the contamination. If the mould has been growing for a while on any wood or composite, it may be damaged. If it’s the garage door, it may no longer be structurally sound. Thus, it may need to be repaired or replaced.
How To Remove Mould from Brickwork
Mould will not grow on untreated concrete or brickwork, but it can thrive there if the surface gets wet. The water then dries leaving mineral deposits. You can notice these as stain patches on the concrete or brick. The mould can then grow on the mineral deposits, not the surface itself.
Not everyone likes bare concrete or bricks, so we often choose to paint garage floors, making them easier to clean when unsightly oil or fluid drips from a vehicle.
By doing this, we are making it easier for mould to grow on the floor. Depending upon the colour, it’s harder to see if there’s a problem. If you intend to paint your garage floor, check out the mould-resistant paints available at your local home improvement store.
You’ll need a bit of elbow grease to get rid of mould entirely from your concrete garage floor. If you have mineral deposits and mould, the experts recommend tackling it with a stiff wire brush.
Before getting down the job, make sure you have the correct mould removal products, a respirator mask, long protective gloves and disposable overalls so you don’t become exposed to the spores which can make you ill.
How To Remove Mould from the Floor
If the floor is painted, use a scraper to remove the paint layer at the same time. To pick up the debris, you will need a vacuum cleaner fitted with a HEPA filter to ensure the spores are not transferred.
#1 best rated Hepa vacuum cleaner, according to Spotless Vacuum:
Once the area is cleared of the apparent mould deposits, it needs to be disinfected with an antifungal cleaner. You can try a commercial mould remover or one of the regular household cleaners that can do the job just as well.
Harsh Chemicals & A Natural Solution To Remove Black Mould
- White Vinegar (Claire’s favourite natural method)
- Tea Tree Oil
- Hydrogen Peroxide
When handling these chemicals always wear gloves and eye protection. Experts recommend you spray the affected area and let it sit for an hour before scrubbing with hot water. If the black mould infestation is severe, you may have to repeat this process two or three times.
How To Remove Mould from Walls
Removing from brick or concrete walls can be done similarly. However, if the wall is made of wood or another porous material such as drywall, it may need to be removed entirely and replaced.
With porous materials, it may look clean on the outside, but the mould may have travelled through the material and cause damage to the structure beyond. If the wall has been painted, you may be able to avoid removal if treated quickly.
Preventing Mould in a Garage
Once you’ve cleaned all the mould from your garage, you’ll want to make sure it doesn’t return. There are some simple steps you can take to avoid mould returning.
One of the simplest things is to keep your garage doors open for a few hours every week. This will help circulate the air in the garage. If the air inside your garage has a lot of moisture, you could consider running a small dehumidifier regularly to cut down on the water in the atmosphere.
You could purchase garage doors which have ventilation louvres or windows to give extra sunlight. As we discussed earlier mould does survive in areas which have direct sunlight or proper ventilation. Here are some practical tips on mould prevention.
Seal your Garage Door
Stopping water from entering your garage is very important. If your driveway is on a slope towards the house, even a light shower can send water into your garage if there is not a proper seal on the bottom of the door. Any standing water in the garage can increase the humidity level enough to promote the growth of black mould.
Check out the structure of your garage regularly. If it detached from the house, it’s even more important to look for any leaks in the roof, windows, or doors. Small puddles in the garage after a rainstorm are a sure indication some part of the structure needs urgent attention.
Allowing water to accumulate in the garage will only make the onset of black mould more certain. If your garage is located where it will always be susceptible to water entering, make sure there is adequate drainage. Some owners have a pit in their garage for excess water that can be pumped out regularly.
Try and keep as much off the floor of your garage as possible. Most of us want to use it as an additional storeroom, and it’s easy to pile stuff in there, but try and keep everything raised. As soon as some moisture gets into things like paper or cardboard boxes, black mould can start to grow. If you aren’t used to organisation, why not try using a planner!
Keep Plants Away from the Garage
There’s a tendency for us to hide the garage behind lots of planting because it’s just a box shape that can detract from the look of a house. However, plants too close to a garage can cause problems by creating cracks in walls that will allow in moisture. The roots can penetrate the structure of the building also and again help black mould to grow.
Making a Garage Mould-Proof
Unfortunately, most garages are unheated, and without a window, which means they can have high humidity, be dark, and unventilated, all the conditions black mould thrives on. If you want to stop mould ever getting into your garage, then make sure there is plenty of light, ventilation, and if it can be heated all the better.
That should take care of the issues which promote black mould growth. If you live in an area of high humidity, consider constructing your garage out of metal, at least using metal studding, and then aluminium or vinyl siding. It is much easier to remove mould from these surfaces that porous materials like wood and drywall.
