Before looking to remove the mould, you should find the cause as it will only keep coming back otherwise. When it comes to black mould around windows, a common cause is damage to the frame.
You should contact a professional to either repair the window frame or carry out a replacement, depending on how severe the case might be.
You can remove mould yourself but the NHS recommend to only do this if the mould covers an area smaller than 1 metre squared. If the mould has spread beyond this or the cause was found to be anything to do with sewage or contaminated water, always contact a professional.
Before starting, protect yourself by wearing goggles, rubber gloves and a mask that goes over your mouth and nose. It’s also a good idea to open up the windows for ventilation but keep doors closed to prevent spreading.
What you’ll need: A bucket, washing up liquid, rubber gloves, goggles, a mask, 2 rags, a plastic bag and either cleaning wipes or a hoover.
Step 1: Fill a bucket with water and washing up liquid
Step 2: Dip a rag into the soapy water and wipe. Don’t brush the mould around as this will cause it to spread.
Step 3: Once removed, use the dry rag to wipe the damp area of the wall and remove any moisture.
Step 4: Throw both rags away.
Step 5: Wipe down or hoover the surface where the mould had been.
If there were any clothes or soft furnishings in the area where the mould had spread, then you should put them into a plastic bag and take them to be professionally dry cleaned or throw them away if you’d rather.
When aiming to get rid of mould around your windows using vinegar, you should always wear gloves to avoid irritation.
Step 1: Fill a spray bottle with white vinegar. Alternatively, wet a cloth with the vinegar and wipe.
Step 2: Thoroughly spray the vinegar over the mould.
Step 3: The vinegar needs time to break up the mould so leave if for 1 hour.
Step 5: Use a scrubbing brush and warm water to scrub away the mould.
Step 6: Wipe the surface down using warm water and leave the area to dry out.
If the mould reappears, try the whole process again. You might also want to combine vinegar with other products such as baking soda or salt to increase your chances of successful black mould removal.
