What is exterior wall cleaning…
Exterior wall cleaning is one method of regular maintenance to keep the building’s appearance clean and to prolong the lifespan of the exterior materials.
As shown in the photo above, even when the paint film on the exterior wall is in good condition, rain streaks, darkening, and moss can occur due to sunlight and structure.
Typically, when the exterior wall darkens or moss grows, the common options are “exterior wall painting” or “high-pressure washing of the exterior wall”.
If it’s within reach, such as around the first floor, it may be possible to clean using a household cleaning machine with brushes or sponges as a DIY project, but it becomes quite difficult for the second or third floors.
Are you facing these issues with dirty exterior walls?
“It’s been 5 years since I painted, and while it’s not urgent, I’m concerned about one side being dirty…”
“Painting is expensive, so I don’t plan to do it yet, but I want to clean the exterior at a lower cost…”
“It’s a three-story building, but is it possible to clean without scaffolding…?”
“Will this dirt come off with just washing…?”
“I’m worried that the detergent might discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior cleaning can solve them!
Why is Kakeru Koumuten’s exterior cleaning popular in Tsurumi-ku, Yokohama?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Tsurumi-ku, Yokohama!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs significant costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior at about 1/10 the cost of exterior painting!
Point 2 Cleaning without damaging the exterior!
We use gentle water pressure instead of high pressure for washing. The brushes used are specialized and clean gently, removing dirt without damaging the exterior.
The detergents used are formulated to prevent discoloration of the sashes and exterior walls!
We also differentiate the detergents used based on the type of dirt, such as rain stains, blackening, and moss!
*Please note that detergents strong against moss can harm or kill plants if they splash onto them, so caution is necessary! Even if a strong moss detergent cannot be used, cleaning is still possible, so rest assured!
Point 3 We can clean the exterior without causing much inconvenience to the neighbors!
By using a special brush to apply a gentle water flow, it is less likely to splash compared to using a hose directly!
The detergent used also has very little odor.
The sound of the machinery used is relatively quiet as it is electric.
That said, if the building is close by, there may still be some inconvenience, so we always make sure to greet the neighbors before starting the work.
If there are cars nearby, we will protect them with car seat covers!
Point 4 The construction period is short!!
For a typical house exterior cleaning, it is often completed in just one day, even for full cleaning!
Since the work is mainly done outdoors, cleaning can be done even if you are not at home!
Of course, we will take detailed photos of the work, and we will send the pictures to you later.
Point 5 We can clean more than just the exterior!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (such as parking lots)
・Carports
・Roofs and solar panels (there may be cases where this is not possible.)
If you have other areas of concern, please feel free to consult with us!
Point 6 We will conduct a site survey before the work!
Before the work, we will check the condition of the exterior walls and joints, and we will greet the neighbors.
We will also check before the cleaning day to ensure that the work can be carried out without any issues.
Point 7 Estimates can be provided using photos or drawings!
We can provide estimates based on photos and drawings (floor plans and elevation drawings) through LINE or email!
However, there may be cases where it is difficult to provide an estimate based on photos or drawings, in which case we will visit the site for an inspection.
Estimates will be sent within 1 to 2 business days after receiving the photos or drawings!
What should you be careful about when cleaning exterior walls?
Next, we will explain the “5 points to be cautious about” during exterior wall cleaning!
Caution 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar walls with many cracks may not be able to be cleaned.
This is to prevent leaks and peeling of the paint film.
Caution 2 Some stains may not come off…
Black stains and rain streaks that have been left for many years may not come off even after cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jollypat finishes.
If you try to forcibly remove black stains or rain streaks from Jollypat exterior walls, it may cause discoloration or damage, so we will use specialized agents to clean gently as much as possible. 
As shown above, even when using specialized chemicals on exterior walls with Jollypat finishes, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean the exterior walls every 3 to 5 years without leaving dirt!
Caution 3 If the joints are severely deteriorated
If the joints of the siding exterior walls are severely deteriorated, it may lead to leaks, and therefore, we may not be able to perform the work.
Note 4 There may be cases where work cannot be performed due to the structure of the building.
It may be difficult to work in areas such as above eaves, above bay windows, or extremely narrow spaces.
We will confirm this during the inspection.
Note 5 We will need to use electricity and water!
During cleaning, we will borrow electricity and water.
If there is no electricity or water outside, additional costs may be incurred, but we can also provide a generator or tank!

The exterior walls of plastered surfaces will be cleaned using a special washing method!
The cleaning method for plastered exterior walls with Jolly Pat finish differs from that of siding and other materials.

As shown in the above photo, we apply specialized chemicals for plastered walls using rollers and other tools for cleaning.
By repeatedly applying the chemicals and washing, we gradually remove the dark stains!
Due to the increased number of processes, the cost may be higher compared to other exterior walls, and there may be cases where stains cannot be completely removed.
