\A patio has always been one of the favourite spots for a family, given the way it provides a calm and comfortable environment. Exposure to the elements makes a patio susceptible to various problems that are usually not found indoors. One of the most common problems that trouble people is their patio turning green. In a region like London, such issues are even more common because of many factors. Understanding the factors behind this issue is crucial before one chooses from the available patio cleaning services in London.
With the right cleaning methods and proper expertise, the green growth can be tackled pretty easily. Before going further, let’s take a look at what causes this issue.
What Causes This Issue?
The green colour that troubles people on such a large scale may result from several causes. Knowing the reason is important before getting started with the cleaning process; otherwise, the same issue will appear again. Algae growth is a pretty common cause. It is marked by a thin layer that turns darker when wet. Usually, this growth is seen on the surfaces of bricks, concrete, and sandstone. Then there is moss growth. Unlike algae, it develops in the joints or between the paving slabs. Moss has a denser, more noticeable texture than algae.
If moisture remains on the patio for long enough, it supports such growth. Moss may grow from adjacent garden areas or other such areas where water and organic matter accumulate easily, especially when there are trees nearby.
And this is one of the reasons why green growth appears along the garden walls or beneath the outdoor furniture. Increasing exposure to sunlight and improving airflow can help slow its return.
How to Remove Green Growth from Your Patio
There is no universal cleaning method that can be applied everywhere because the suitability of a method depends on the severity of the growth and the type of paving one has. Here’s a list of some effective ways to deal with this issue:
Start with Brushing and Basic Cleaning: For light green patches, start with a stiff-bristled broom and clean water For light green patches, start with a stiff-bristled broom and clean water. Before one starts scrubbing the affected areas, the leaves, dirt, and other forms of loose debris need to be swept away.
The moss from joints can be removed with a narrow paving brush. A wire brush should not be used on delicate stones or other finished surfaces because it may lead to scratches or even damage. Once the loosened material has been rinsed away, the patio should be left to dry. In case the green film returns, a more effective cleaning method is needed.
Use a Suitable Patio Cleaner: When the growth has become well established, it demands the right patio-cleaning product that works for your paving material. While using that product, one should follow the manufacturer’s instructions regarding dilution, application, and rinsing. No other cleaning chemical or household bleach should be mixed with it indiscriminately.
Consider Professional Washing: In case algae, moss and ingrained dirt have become too stubborn for normal cleaning methods, it is time to get professional help. Skilled operators can adjust their equipment and techniques to suit a particular surface and effectively remove the growth without causing any damage to the paving.
Some people think that using the professional tools and products themselves will produce the same results, which is not true. Excessive pressure can easily erode softer stone, remove the jointing materials, or damage some particular finishes. Professionals use the right nozzle and pressure setting and maintain an appropriate distance from the surface to ensure the best results without any damage to the surface.

FAQs
-
What should I do if my patio turns green a few weeks after cleaning?
Cleaning alone does not solve the underlying problem. Thoroughly check if shaded paving, standing water, damp joints, accumulated debris, or something else is causing the green growth. Start by checking the drainage, sweeping away debris and assessing airflow.
-
Should I use a pressure washer on block paving or sandstone?
This may be used, but not in every case. While using it, you must adjust the technique to suit the type of material being washed; otherwise, it may lead to damage.
-
Should I be worried about getting sick if green algae are present on my patio?
Such growth is not harmful in general, but a wet layer reduces grip. This increases the risk of a fall. Whenever you are cleaning it, algae present on steps and entrances should be prioritised.
-
When should I clean my patio for the best results?
Spring is regarded as a practical time. This is because it lets one remove the accumulated growth before one starts to use the garden more frequently.
-
How often should I have my patio professionally cleaned?
There is no fixed schedule for every patio because a well-drained patio that receives plenty of sunlight may need less professional care compared to one that is beneath trees or shaded by a wall.
