What is exterior wall cleaning…
Exterior wall cleaning is one method of regular maintenance to keep the building’s beautiful appearance and prolong the life 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.
When the exterior wall becomes dark or moss grows, the common options have been “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 yourself with a brush or sponge using a household cleaning machine, but it becomes quite difficult for the second or third floor.
Do you have any concerns about dirt on your exterior walls?
“It’s been 5 years since I painted, and while it’s not in need of painting, 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 with just washing…?”
“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 popular in Katsushika-ku?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning well-received in Katsushika-ku!
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 1/10 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 we use are specially designed to 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 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 directly spraying water with a hose!
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 the work begins.
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 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 not only the exterior but also other areas together!
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 any 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 greet the neighbors.
We will confirm on the day of cleaning that there are no issues for the work to proceed smoothly.
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 cases where it is difficult to provide an estimate based on photos or drawings, 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 aware of when cleaning exterior walls?
Next, we will explain the “5 points to be cautious of” when it comes to 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 darkening and rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from exterior walls with a Jolly Pat finish.
If you try to forcibly remove darkening or rain streaks from Jolly Pat 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 agents, some streaks from rain may remain on Jolly Pat finished or plastered exterior walls, so caution is necessary.
Depending on sunlight and location, it is recommended to clean 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 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!

・We will wash off moss, stains, and rain streaks from the exterior walls using a special brush!
We will clean plastered exterior walls using a special cleaning method!
The cleaning method for plastered exterior walls with Joripatto finish differs from that of siding and other materials.
As shown in the above photo, we apply specialized cleaning agents for plastered walls using rollers and other tools for cleaning.
By repeating the application of the cleaning agent and washing, we gradually remove the black 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 |
|---|---|
| Concrete for Parking Lots and Other Areas | 500 yen–550 yen/㎡ |
| Exterior Cleaning of Walls and Fences | 500 yen–600 yen/㎡ |
