How to Keep Your Exterior Doors Mould Free

Mould on exterior doors not only looks unsightly, but it is a health hazard too. So how do you get rid of it when it appears? And what can you do to minimise the chances of encountering it in the first place? Stay tuned as we answer these questions and more in today's blog post, which is all about keeping exterior doors free of mould on a year-round basis.

What Causes Mould?

Mould loves moist conditions. It will only grow where moisture exists. Damp problems and condensation are the two primary causes of mould around the home, including exterior doors. Mould grows not just on timber doors but on uPVC doors as well. It can also affect painted metal doors in certain conditions.

Mould Prevention: What to Do to Retard the Growth of Mould on Exterior Doors

As with almost any household maintenance problem, taking preventative measures requires less time and effort than implementing a cure. With this in mind, we are going to examine a few ways in which you can retard or eliminate mould growth on your exterior doors before we discuss how to get rid of mould once it has established itself.

  • Apply Mould-Resistant Paint or Stain Blocker – One of the simplest and most effective ways to prevent mould from gaining a foothold on your exterior doors is to paint them or apply a quality stain blocker. Timber and metal doors are the best candidates for mould-resistant paint, while uPVC doors are best treated with a stain blocker.
  • Improve Airflow – Moisture tends to form in areas where airflow is poor. If you want to prevent mould from growing on your exterior doors, make sure the air is flowing freely around your property. If there are any fences, hedges or porches restricting the movement of air, consider removing them.
  • Clean Regularly – Mould needs oxygen, water and nourishment to survive. You can remove any potential sources of nourishment by cleaning metal and uPVC doors regularly. It won’t eliminate the possibility of mould in the future, but it will make it less likely.
  • Wipe Down in Wet Weather – If conditions are particularly humid or wet, wipe down your exterior doors now and then.

Try all these suggestions and the chances of mould growing on your exterior doors will be significantly reduced. Even if you can only implement 1 or 2 of these ideas, your efforts are sure to reduce the chances of mould making an appearance in the future. This is assuming that your property is free of any damp issues of course.

Mould Elimination: Removing Mould From Exterior Doors

If you already have mould on your exterior doors and you want to know how to get rid of it quickly, safely, efficiently and with a minimum of fuss, we suggest following these steps:

  • Pour 60 ml of bleach and 15 ml of dishwashing soap into an empty spray bottle.
  • Fill another spray bottle with a 1:1 mixture of white vinegar and water.
  • Wet the surface of the affected door with your garden hose, using a fine mist setting.
  • Use a broom to scrub the surface of the door while it is still wet.
  • Spray the door with bleach and dishwashing soap solution, and scrub the surface vigorously with the broom again. Be sure to spray and brush corners and crevices thoroughly.
  • Rinse the door with the hose. The bleach and soap solution will kill all live mould spores immediately, so there is no need to wait once you have finished scrubbing for the second time.
  • Spray the door with your vinegar and water solution, and then go over it one last time with your broom. This will remove any traces of the bleach and soap solution that may remain, after which you can rinse with water again. Your door should now be clean and, more importantly, free of mould.

This method works on almost all exterior doors, including timber, painted metal and uPVC doors. However, if you have any concerns about potential damage, we recommend consulting the manufacturer or supplier of your exterior doors before trying it. Of course, Rock Solid Doors can also help!

The fitters were very polite, thorough and clean during the installation. Very pleased with the purchase.The fitters were very polite, thorough and clean during the installation. Very pleased with the purchase.Just wanted to drop you a quick note to say thanks for the new door and to let you know how pleased we are with it. Kaye was delighted when she got home and saw the finished job, it really does look the bee’s knees and has transformed the appearance of the entrance. Its been a real pleasure dealing with you both and rest assured we’ll unreservedly recommend your company whenever we get the opportunity. The only problem I have now is that Kaye has started muttering about replacing patio doors and french windows at the back of the house. So unless I can rein her in pretty damn quick you may well be hearing from us again.Thanks again chaps for a great job at the right price and with the minimum of fuss and disruption. Best regards, Steve

100% recommend Paul and Harry a great father and son team! I'm so pleased that we used them to supply and fit our new front door. Straightforward to deal with from start to finish and communication throughout was excellent. They are extremely knowledgeable and were able to offer advice and suggestions when we were choosing the door we wanted. Nothing was rushed during the installation with great attention to detail. They took away our old door and frame and left everything clean and tidy at the end of the job. Thank you, Harry, for taking the time to go through everything with us at the end of the job, much appreciated. I would not hesitate in using Paul and Harry again. Thank you both so much, we are so pleased!

Had a door fitted by these very friendly chaps about 18 months ago. We're very happy with it. When an issue arose with the mechanism, they came out and fixed it in about 5 minutes and it's as it if is brand new again. Very pleased, would highly recommend.

Highly recommend. We had our front door fitted by this lovely team. They were friendly, helpful, willing to listen to me debate options and provided helpful advice for choosing the right door for us. When he had a slight issue (no fault of their own) they came out to us the very next day and sorted it. Such a good supplier to work with!

Brilliant service. No hidden costs or fees and no heavy sales tactics. Very open and clear from the start, and they worked really hard to fit a great new door in our thinner than average doorway! Great value and great result. Will be recommending to all.

Highly recommend Rock Solid doors. We have used this friendly family company several times and have recommended them to others who have been equally impressed with the high standard of work and the product. We have received quick service and found them to be very reliable knowledgeable with no hard sell. The installations have been carried out professionally and they go the extra mile to ensure you are happy with everything. The external doors are robust and we are impressed with the quality of the product.

Faultless customer service from a fantastic company to do business with. From start to finish it’s been a pleasure buying composite doors from Rock Solid Doors – in fact, we were so impressed with the front door and installation service they provided (we opted for a Solidor Ludlow 2 with 2 x fully glazed side lights) that we got them back to supply our utility door (Windsor Solidor – fully glazed) shortly afterwards. Paul dealt with our initial queries promptly, came to measure on site and provided a competitive quote very efficiently. These guys are first-rate craftsmen and know their stuff: evidenced by working around a couple of quirky construction issues without any problem – leaving us really impressed with the end product. It’s great to come across a local business that takes pride in what they do, going the extra mile for customer satisfaction – we cannot recommend Rock Solid Doors highly enough! Thank you Paul and Harry!

Brilliant service from Paul at Rock Solid; our letter box seal had gone causing a slight leak - he responded immediately, attended this week and fixed with a new gasket. Would highly recommend the product and the service.

I ordered my Vogue Rock door with the Ocean glass from Rock Solid Doors at the end of 2021. I had a number of criteria when searching for my new entrance door. It’s ability to insulate had to be A rated. I also wanted it to have a good quality locking mechanism that is smooth in action. My new door needed to be modern with a pane that lets plenty of light in and thus goes lower than the half line on the door, while leaving sufficient height for the letter box, so it is sufficiently high to be comfortably reached by our postman. The Vogue Rock door provided all that and more. I love sailing and the Ocean glass design evokes the lines of a sail in a beautifully minimalistic fashion. It also makes the door look unique, which is always a bonus. During my search for the perfect door I had lots of technical questions too. Only Paul and his colleague from Rock Solid Doors were able to answer all my questions and provide a door that offered what I was looking for. They supplied and fitted my new door in early 2022. My heating bill has gone down noticeably, as a result. With the golden oak wood grain on the outside, my door looks beautiful and elegant. Everyone who comes to the house for the first-time comment on it. The multi-locking mechanism has a smooth action and it is easy to use. The white wood grain on the inside finishes off the hallway like a designer window and door in one. Paul and his colleague went out of their way to make sure that I have the door and the finish just, as I wanted and that it worked seamlessly there on. We could not be happier. Thank You!
