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 life of the exterior materials.
As shown in the photo above, even if the paint film on the exterior wall is in good condition, rain streaks, darkening, and moss can occur due to sunlight and structure.
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 is within reach, such as around the first floor, it may be possible to clean with a household cleaning machine using brushes or sponges as a DIY project, but it becomes quite difficult for the second or third floors.
Do you have any concerns about dirt on your exterior walls?
“It’s been 5 years since I painted, and while it’s not time for a repaint, 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 can it be cleaned without scaffolding…?”
“Will this dirt come off just with cleaning…?”
“I’m worried that the detergent will discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning so popular in Aoba-ku, Yokohama?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Aoba-ku, Yokohama!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs high costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior at about one-tenth the cost of exterior painting!
Point 2 Cleaning without damaging the exterior!
We use gentle water pressure instead of high pressure for cleaning. The brushes used are specially designed to clean gently, removing dirt without damaging the exterior walls.
The detergents we use 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 on them, so caution is necessary! However, even if we can’t use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Can clean the exterior without causing much inconvenience to neighbors!
By using a special brush with a gentle water flow, it is less likely to splash compared to using a hose directly!
The detergent used also has little to no 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 Short construction period!!
For a typical house exterior cleaning, it often can be completed in just one day, even for full cleaning!
Since the work is generally done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed photos of the work, and we will send the pictures to you later.
Point 5 Can clean areas other than the exterior all at once!
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 construction!
Before construction, 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 and drawings!
We can communicate via LINE or email, and provide estimates based on photos and drawings (floor plans and elevation drawings)!
In some cases, it may be difficult to provide an estimate based on photos or drawings, and in such cases, we will visit the site for an inspection.
We will send the estimate within 1 to 2 business days after receiving the photos or drawings!
What should you be aware of when cleaning exterior walls?
Next, we will explain the “5 points to be cautious of” 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…
Stains from years of neglect, such as blackening or rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and blackening from exterior walls with Jollypat finishes.
If you try to forcibly remove blackening 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, some streaks from rain may remain on Jollypat finishes, 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 When 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 construction is not possible due to the structure of the building.
It may be difficult to perform work in areas such as above eaves, above bay windows, or extremely narrow spots.
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 apply, but we can also provide a generator or tank!

As shown in the photos above, we apply special chemicals for plastered walls using rollers and other tools for cleaning.
