What is exterior wall cleaning…
Exterior wall cleaning is a method of regular maintenance to keep the building’s appearance clean and to prolong the life of the exterior materials.
As seen in the photo above, even when the paint film on the exterior wall is in good condition, rain streaks, discoloration, and moss can occur due to sunlight and structure.
Typically, 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 might be possible to clean it yourself using a brush or sponge with a household cleaning machine, but it becomes quite difficult for the second or third floors.
Are you facing these issues with exterior wall stains?
“I painted 5 years ago, and while it’s not time for a repaint, I’m concerned about one area that looks 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.”
For those with such concerns, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning popular in Shinagawa-ku?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning well-received in Shinagawa-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 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 come into contact, 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 than using a hose directly!
The detergent used also has little to no odor.
The machine used is electric and relatively quiet.
That said, if the building is close, there may still be some inconvenience, so we always greet the neighbors before starting work.
If cars are nearby, we will protect them with car seat covers!
Point 4 Short construction period!!
For regular single-family home 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 construction photos 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)
・Concrete surfaces (such as parking lots)
・Carports
・Roofs and solar panels (there may be cases where this is not possible.)
Please consult us about any other areas of concern!
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 visit the site beforehand to confirm that the work can proceed smoothly on the cleaning day.
Point 7 Estimates can be provided using photos and drawings!
We can provide estimates through LINE or email by exchanging photos and drawings (floor plans and elevation plans)!
In cases where it is difficult to provide estimates 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 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 Jolly Pat finish.
If you try to forcibly remove black stains or rain streaks from Jolly Pat walls, it may cause discoloration or damage, so we will use specialized agents to clean as gently as possible. 
As shown above, even when using specialized chemicals, some rain streaks may remain on Jolly Pat finish walls, so caution is necessary.
Depending on sunlight and location, it is recommended to clean the walls every 3 to 5 years without leaving dirt!
Caution 3 If 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 spaces.
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 generators or tanks!

The exterior walls with plaster will be cleaned using a special cleaning method!
The cleaning method for plastered wall exteriors, such as Joripatto 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.
