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 above photo, even if the paint film on the exterior wall is in good condition, rain streaks, discoloration, and moss can occur due to sunlight and structure.
When the exterior wall becomes discolored 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 it DIY with brushes, sponges, or household cleaning machines, but it becomes quite difficult for the second or third floors.
Are you facing these issues with exterior wall dirt?
“I painted 5 years ago, and while it’s not in need of painting, I’m concerned about one area that’s 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 will discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior wall cleaning can solve them!
Why is Kakeru Koumuten’s exterior wall cleaning popular in Shinjuku-ku?
Here are the “7 points” that make Kakeru Koumuten’s exterior wall cleaning well-received in Shinjuku-ku!
Point 1 Overwhelmingly low cost
Typically, exterior wall painting and high-pressure washing require scaffolding, which inevitably incurs high costs.
Kakeru Koumuten’s exterior wall cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior walls at about 1/10 the cost of exterior wall painting!
Point 2 Cleaning without damaging the exterior walls!
We use gentle water pressure instead of high pressure for cleaning. The brushes used are specialized and clean gently, removing dirt without damaging the exterior walls.
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! However, even if a strong moss detergent cannot be used, 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 machine used operates quietly 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 cars are nearby, we will protect them with car seat covers!
Point 4 Short construction period!
For regular residential exterior cleaning, it often can be completed in just one day, even for full cleaning!
Since the work is primarily done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed photos during the work and send them to you later.
Point 5 Can clean areas other than the exterior as well!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Ground (concrete parking lots, etc.)
・Carports
・Roofs and solar panels (some restrictions may apply.)
Please feel free to consult us about any other areas of concern!
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 greet the neighbors.
We will also confirm on-site before the cleaning day to ensure that the work can proceed without 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!
In some cases, it may be difficult to provide an estimate based on photos or drawings, and if that is the case, 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…
Black stains and rain streaks that have been left for many years may not come off even with 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 walls, it may cause discoloration or damage, so we will use special agents to clean them gently as much as possible. 
As shown above, even when using special 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 When the joints are severely deteriorated
If the joints of the siding exterior wall 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 the cleaning process, 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 with plaster will be cleaned using a special washing method!
The cleaning method for plastered wall exteriors, such as Jolly Pat finish, differs from that of siding and other materials.
As shown in the photos above, we apply specialized cleaning agents for plastered walls using rollers and other tools for cleaning.
By repeatedly applying the cleaning agents and washing, we gradually remove the dark stains!
Due to the increased number of processes, the costs may be higher compared to other exterior walls, and there may be cases where stains cannot be completely removed.
| Minimum Charge | 15,000 yen |
