Why Mold Grows On Windows
Mold develops around windows because of the difference in temperature from the inside to the outside and this causes condensation.
Mold loves damp warm places to breed and grow, your windows are the ideal place.
We’ve created this problem for ourselves, we have a need to seal up our homes to reduce the potential of any energy loss.
This is why mold on window sill from condensation is important to take care off. It means there is no ventilation to prevent the mold from setting up their home on your window sills.

The problem starts with not ventilating our homes and not allowing any moisture to escape.
When the air laden with water hits the window, it forms window condensation, and this provides an ideal environment for mold to grow.
We have created homes with no air flow, we need this air flow to circulate around our home to prevent mold spores taking hold and starting up their own breeding grounds.

If you are looking for how to get rid of mold on window sills then you need to consider how the mold is taking hold. Are you providing it with the perfect environment in which to live?
As we’ve just discussed we need to make air flow, this will help to stop the mold from forming. You need to supply some sort of ventilation to the room with the problem.
Some windows come with ventilation built-in. This is something that we had to ask for when replacing our windows, it’s something that’s offered but not something they ask when they are designing your windows.
You might wonder why and that’s because it will cause a draft and make the room less energy efficient.
How To Improve Air Flow In Your Home
If you don’t have vents on your windows consider opening your windows, or having some sort of air movement, a dehumidifier is good, even a fan causes air flow and this might be enough to reduce the potential for mold to grow.
But you will need to do something, it’s not going to get better unless you take action.
What about a plant?
Plants are a great way to help improve the air quality, some plants are really good at making the air in our homes better and is something you might want to consider.
I have a lot of plants in my home and they do make a difference as to how much moisture there is in the air.
But the most important tip is not to seal up your home, let the air flow. When the air can’t flow any spores of mold won’t be blown away. Here’s an article on improving the ventilation in your home.
This simple tip might help prevent some mold growth in your home.
Tackle This Mold Now
Getting rid of any mold is important, mold spreads by releasing microscopic spores into the environment and these spores can cause ill-health as well as new mold patches; it is not healthy to live with mold.
How you treat the mold will depend on how quickly it returns.
It’s very difficult to kill the roots of mold and most products just remove the surface colour and spores but leave the roots behind which means the mold will just re-grow and allowing the problem to start again.

However, if you don’t aim to tackle the problem properly you will have to continue to deal with mold, spending money on cleaning products, whereas if you addressed the problem the mold should go away.
But you do need to address the issue that caused the problem in the first place.

How To Clean Mold From Window Sills
Finding the right product to kill mold: I’m often asked: Will bleach kill black mold ?
- Bleach will not kill the mold on contact and is not an effective way to treat mold on any surface. If the surface is porous, the bleach is not an effective method to kill mold because it can’t penetrate the surface to kill the roots. Using bleach is great at removing the mold colour but you will have to keep reapplying regularly as it regrows. So, whilst it gets rid of the surface colour of the mold it doesn’t penetrate and kill the roots, allowing it to re-establish and re-grow.
- Borax is supposed to be great for cleaning mold but you do need to scrub the surface, and this will release the spores into the atmosphere and can spread the mold. I’ve been told that leaving the borax on until it is completely dry should eliminate the mold. However, this product isn’t widely available and in some countries, it’s banned, and for this reason I’ve never personally used it.
- White Vinegar is a popular cleaning product for those people who are trying to avoid chemicals in the home, unfortunately, it doesn’t kill all forms of mold and this means it isn’t really an effective cleaner if you are looking to remove and kill all mold growth. This is a shame as I like using a natural product to clean with.
- Ammonia is not able to penetrate a porous surface and so some of the mold could survive and continue to grow. Whilst, it’s good for surface cleaning it’s not going to solve the problem long-term. It is important that you don’t mix ammonia with bleach as this creates a poisonous gas, this combination of chemicals makes a chemical warfare.
- Hydrogen peroxide is an anti-fungal product, which will kill the bacteria that it meets and is a safer product to use than bleach. Being anti-fungal it will kill the mold. This is good news as this product is relatively cheap to buy.
- Hot soapy water is the most ineffective way to kill mold, it can remove some of the mold, but it won’t kill the mold at all; what it will do is allow the mold to spread to new surfaces as spores are released into the atmosphere.
- Baking soda is a great cleaning product for lots of different cleaning tasks and one of those tasks is killing mold and absorbing the moisture too. This makes it a great treatment for mold as mould needs moisture to grow. However, it’s a very mild disinfectant and in some cases it might not be strong enough to completely remove the mold.
- Tea tree oil is the best treatment for killing and tackling mold on window sills, unfortunately, it is the most expensive option too. However, it can penetrate into the roots of the mold and can kill and remove all traces of mold. This is just one property of tee tree oil and is something you should have on-hand at all times. Use about I teaspoon of tea tree oil to 1 cup of water.
Products Purchased For Mold Removal
If you were to look for cleaning products that remove and clean away mold you won’t go home empty handed.
But, do they work and how?
I’ve looked at a few products especially when it comes to mold as it seems to be a common problem but one that seems difficult to resolve.
If there was a simple remedy, then so many products wouldn’t be available.
I tried Astonish mold removal spray and I must admit it seems to work, the mold does go away but the product smells bleachy and this tell me that in some places the mold will come back.
It’s relatively cheap and if you are looking for a quick fix this might be the solution that you go for.
This company doesn’t test on animals and the product is vegan friendly.
Another product that is highly recommended but one I haven’t tried is HG Mould spray, this product is not tested on animals. I’ve been told is very good at removing mold, but it’s not one that I’ve tried.
There are other variations on the market of similar products but again I’ve not tried them, but beware if they contain bleach it might just be masking the problem rather than removing it completely.

How To Remove Black Mold
Sometimes it might be appropriate to call in professional help especially if the mold is bad, there are some types of mold that are really dangerous to your health and you might need to ensure that this isn’t the case with the mold you have.
There are different ways and options for treating mold, all with varying results, but with all of them it’s important to follow the instructions and not to mix products. Mixing products is dangerous.
Choosing The Right Mold Product For You
You need to choose a product that will remove the mold, if you opt for a product that might not completely destroy it remember it’s going to come back. So, be prepared to tackle the mold again in the future.
Whatever product you are using protecting your health is key. So, if the product recommends wearing gloves then follow these instructions. A face-mask might also be required to prevent mold spores entering your body.
Protecting The Area Around Your Window
Before you start cleaning the mold around the window sill protect the area around the window. You don’t want the product damaging anything else and you want to catch as many spores as you can.
Something that can be rinsed or thrown away is an option to consider. Depending on the product you are using you will want to let the product do it’s work before wiping and cleaning the area down.
It’s so important to read the instructions of the mold removing product so you know what you need to do.
How To Clean Mold And Mildew From Windows
I don’t want you to think that this is an easy project, especially if the mold has taken hold of the area. When you have a really bad patch of mold in reality it’s going to take more than one session to get rid of it.
If you don’t address the problem as to why you have mold in the first-place chances of it coming back are very high. If it’s around your window, often this is a ventilation problem and unless you take steps to address the issue it’s just going to come back.
How To Actually Clean The Mold
Whatever product you are using I would wear protective gloves as a minimum. The first thing I do is spray the cleaning product onto the cloth. I don’t want the spray to allow the spores a chance to fly away.
Then slowly and carefully remove the surface mold. I swap cloths before going over the area a second time because I don’t want to re-infect the area with the fungus that is in the first cloth.
Wash all your cloths in hot water and I would add a drop of tea tree oil in to kill any spores that might still be lurking on the cloths.
How To Prevent Mold On Window Sills
Often, I’m asked ‘how to stop condensation and mold on windows?’ the answer is simple, mold loves damp warm places, and this is something that we create when creating sealed homes.
The condensation forms on windows because of the different temperatures and mold simply sees this as an ideal home and quickly takes hold.
To prevent mold growth you need to remove the potential new home, this means proper ventilation, and tackling any mold as soon as it’s seen.
Plants are a great way to improve the quality of the air in your home, check out this list of 20 plants that can improve air quality.

How To Remove Mold From Window Sills
You will need your mold removing product, read the instructions and iradicate the mold.
However, as with all concepts of mold removal the most important thing to do once the mold is gone is to clean the widow sills on regular basis.
This will help ensure you can spot any potential problems before they take hold and are difficult to remove.
What I Did To Remove Mold Around Windows
We had windows without vents and mold was a constant, I couldn’t keep on top of it, it drove me mad.
We had new windows installed and I insisted on vents on every window and we’ve had no mold. I know this isn’t a solution for everybody, but ventilation is the only way to prevent mold taking hold.
How To Get Rid Of Mold From Sealant?
If the mold has entered a porous substance like sealant it’s more difficult to kill as you need to get into the root structure.
If you choose a bleach based product you won’t see the mold but you will need to keep reapplying so the mold stays away. But you won’t have actually killed the mold.
Sometimes it’s easier to remove the sealant and to clean the area and reapply fresh sealant.
Preventing Mold Growth
Mold is a living organism and is looking for the most ideal place to live and grow. Prevention is so much better than dealing with the problem.
Ventilation is the most important thing that you can do, air flow prevents the perfect conditions from forming. If you still have a damp environment, then you need to think of other ways to dry out the area.
A dehumidifier is a good option, it allows the moisture to be removed from the air and this dries up the potential for having a damp room and can slow down the regrowth of mold.
Do You Know How To Remove Mold From Window Sills?
If you have mold on your windows already you need to find a product to get rid of the mold.
Think about buying plants to help combat moisture in the air.
Soap and water isn’t going to get rid of this, you will need a product that can get in and destroy the mold including the roots.
You have options, tea tree oil is amazing, but it is expensive. Hydrogen peroxide is another option that will kill the mold. Don’t use bleach on mold, it doesn’t kill it. The mold will grow back.
Prevention is always better than curing the problem, look at the room and decide if there are any ways in which you can reduce the potential of mold.
Can you ventilate the room? Can you reduce the amount of water in the atmosphere to reduce the potential of creating the prefect home for mold?
Oh, we have SO had a problem with this. Thanks for sharing 🙂 Stopped by from Fellowship Friday
Thank you for visiting 🙂
We have this problem in a huge way during the winter. We have standing puddles of water in the window sills on cold winter mornings, and lots of mold to follow. I thought it was a problem with our windows (it’s a new house).
Bleach diluted in a heavy duty spray bottle works perfectly and easily to kill the mold, though I wish it never formed in the first place. I spray it on and leave it for a while, then wipe it all off. No more mold…at least not for a while.
Thank you for visiting, I think a lot of time the mould happens because we seal our homes up too well, we forget the airflow that prevents the mould growth. I think it is something that many of us have to deal with on a regular basis unfortunately. Thanks for taking the time to comment 🙂
Was going to read the article, but something kept bothering me…. Oh, yes, it is MOLD not mould.
Hi Mary, Mould is the English spelling of the word and is therefore correct 🙂 But thanks for pointing this out I am only too happy to clarify any point in an article 🙂
Thanks for the tips, very useful at this time of year, especially!
You are welcome! Thanks for visiting and taking the time to comment! 🙂
It’s “too” happy, not “to” in your sentence above. Spelling counts when writing for others. 🙂
Thank you for noticing! I have corrected it! Spelling is very important but sometimes an odd error slips through! 🙂
i moved in to a newly built home 2 years ago in the month of november and had awful mold by christmas. been fighting it until i discovered dehumidifiers are a marvel!!!! the one in my living room at my french doors i empty every 6 days of over a pint of water! and the master bedroom one next to the french doors there i empty it every 7 days of over a pint of water too! no more mold! gee wiz no wonder we had a mould problem all that water. dehumidifiers are the way to go.
I do love dehumidifiers but if the home has enough circulation of air then mould shouldn’t be a problem. It is a buy product of insulated homes! We have used and still do use dehumidifiers around the home but I want a more cost effective option! 🙂 Have a great week!
at the cost of 22p a week its a snip. my time is worth so much more. have a nice week:}
It’s by-product, not buy product
Thanks for noticing I will update the post! 🙂
how do you use/apply the baking soda? I also have black mould/mold on my bathroom ceiling.
I just make it into a paste and spread it onto the mould, if you can leave it for a few minutes to work its magic the better results you will get. If you make a thick paste (use less water) and use a cloth to apply to the mould. Hope this helps!
How do you use the tea tree oil?
Hi Susan, I just dilute a few drops in water in a spray bottle, shake well and apply. Nothing technical in my methodsI like to keep things simple! 🙂
Hello, Susan,
The caulking, paint and window casing of some of my windows are stained with mold. During the cold months they definitely produce condensation so I open the blinds & draperies, turn on the heat and the ceiling fans in those rooms to no avail. I’ve applied a paste of baking soda, hydrogen peroxide, five different essential oils known to be antifungal: 2 different tea tree oils (Melaleuca alternifolia & Melaleuca quinquenervia), rosemary essential oil, clove essential oil and cinnamon essential oil and have allowed it to sit then scrub with a toothbrush. Some of the staining is removed but not all. Would you suggest I use bleach for the staining then apply a light mist of the essential oils diluted in water or hydrogen peroxide to kill it?
Thank you in advance!
-Sarah
Sometimes I really hate caulking it is a nightmare for getting clean! You have certainly tried to tackle the problem and you have opted for some great products! Bleach should work for the staining, but it might damage the caulking! I would use a very mild bleach to remove the staining and rinse well before using a tea tree oil to kill the mold. To keep this from coming back I do fear that it is going to be something you will have to keep a very close eye on!
Sharon, I love the way you deal with people! Set them straight in the nicest way possible. 🙂 And I love all the information on mould/mold killer.
Thanks,
Lindsey
Thank you for your kind words! I’m glad you liked the information too! 🙂 Thanks for taking the time to read and comment!
I never knew that to stop the mold from forming you need to supply some sort of ventilation to the room. I had to get remediation done to my windowsill after mold piled up on it. Thanks for the tips for tackling mold on windows.
It’s such a simple tip but it works! Thanks for stopping by and commenting! ?
Hi I have mold on the back of a vinyl poster. How can I clean it off so the rare poster is not damaged? Yes the wall is what caused the mold. Thank you
With anything that is delicate or rare is to take extreme caution. Because I can’t see the poster I would really be cautious as to how you tackle this problem! I would try to wipe it off with a cloth, if it doesn’t come off I suggest looking into a specialist to see what they say!
I can’t believe how rude people are. This is a page with cleaning tips- not political opinions or slandering or anything even remotely malicious. It’s like a bunch of 13 year olds stumbled onto this page after their mother’s scolded them. Thank you, Sharon, for taking the time to post a page full of great tips and being very gracious and diplomatic when dealing with people. Let’s hope they learn a bit of humility.
Thank you for your kind words! ?
Thank you so much for these wonderful tips! We are currently renting a small farmhouse that was built in 1960 and it still has the original windows that slide sideways to open. All of the windows collect moisture and we have been struggling with mold issues. We have 3 small children (one of whom has asthma) so we have been looking for effective ways to rid our home of the mold.
I’m so glad you found these tips helpful! ?
People do make spelling mistakes so quit complaining about how it’s supposed to be spelled, were interested on how and what to use to get rid of it not the way it is spelled!
I agree people come on these sites just to criticize those that are trying to give helpful information to others. They need to zipper there mouths up and take a class on HOW TO SHOW CONSIDERATION AND RESPECT to others. They must be very unhappy people so get a life and be happy!
I appreciate you helping me learn more about mold. I didn’t know that bleach doesn’t kill mold. I wouldn’t any mold to come back. I might need to rethink what I sometimes use to clean up mold.
The main reason behind the increasing the mold is moisture. Once mold comes in house people try to remove it by itself with bleach and another chemical. But they forget about all this thing contains water and when you remove it by bleach it gives more power to mold. So always avoid the bleach and other chemicals for the mold removal. You should take proper inspection of the house by mold inspector and start following step by step advice by the mold inspector which help to goodbye mold forever. If you take the right step then a mold isn’t a big problem. Cheers!!!
the facts have been discussed is really important. Thank you so much for sharing a great post.
Thanks for sharing the ways to protect window sills from molds. I was not sure what products to use and how to do it effectively.
