Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Preparation
If there are plants or vehicles nearby, we will prepare the area before starting the cleaning!
2. Cleaning of Exterior Walls, Wooden Decks, Carports, and Balconies
We will sequentially perform cleaning (washing) of exterior walls, wooden decks, carports, balconies, and more!
Using a machine that mixes detergents and a specialized extendable brush, we will spray the exterior wall cleaning detergent from the top down!
The tip of the specialized brush sprays water and detergent, allowing us to reach even three-story buildings! We will also clean the rain gutters and piping!
For exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brush we use is specially designed to clean gently, ensuring that dirt is removed without damaging the exterior walls.
Since we only use electric machines, there will be no loud noises or disturbances during the work!
The detergents we use are formulated to avoid discoloration of sashes and exterior walls!
We also differentiate the detergents used based on the type of dirt, such as rain stains, blackening, and moss!
*Caution is necessary as detergents strong against moss can harm or kill plants if they splash onto them!
Even if we cannot use moss-resistant detergents, rest assured that exterior wall cleaning is still possible!
We will thoroughly remove blackening and moss from the exterior walls!
3. Water Washing
After completing the detergent wash of the entire exterior wall, we will proceed with water washing from the top down again.
We will rinse carefully to ensure no detergent is left behind!
We will thoroughly rinse away the detergent!
The exterior wall we cleaned this time had noticeable blackening and green moss, but after the exterior wall cleaning, the blackening and moss were beautifully removed, giving it a brighter overall impression!
Thank you for trusting Kakeru Koumuten Co., Ltd.!

What are the advantages and disadvantages of exterior wall cleaning?
Exterior wall washing is a cost-effective maintenance method that restores the aesthetic appeal of buildings at a low cost. Here are the advantages and disadvantages!
Advantages of Exterior Wall Cleaning
First, let’s introduce the advantages of exterior wall cleaning!
1. The building maintains a sense of cleanliness and has a beautiful appearance
As time passes, dirt, mold, and moss tend to accumulate on the exterior walls, but regular cleaning can remove these stains. By performing exterior wall cleaning, the entire building will have a sense of cleanliness and a beautiful appearance.
Furthermore, when the exterior of the building becomes beautiful, the surrounding environment also appears brighter and cleaner.
Unlike high-pressure washing, exterior wall cleaning can be done without damaging the walls.
2. Low cost
Since cleaning can be done without setting up temporary scaffolding, it is possible to restore aesthetics at a lower cost compared to exterior wall painting or high-pressure washing!
3. Short construction period
Unlike high-pressure washing or exterior wall painting, exterior wall cleaning can generally be completed in one day!
4. No noise
Since only electric machines are used, the lack of loud sounds or noise is also an advantage of exterior wall cleaning!
Disadvantages of Exterior Wall Cleaning
On the other hand, there are also disadvantages to exterior wall cleaning!
1. Certain costs are involved
First, it should be noted that cleaning incurs certain costs.
If you hire a professional contractor, the cleaning work, the detergents used, and any painting will incur certain costs, so it is necessary to plan a budget in advance.
Kakeru Koumuten Co., Ltd. offers free estimates, so please feel free to consult with us!
2. Consideration for the surroundings is necessary
During the cleaning process, it is possible that the work may affect the building and the surrounding environment. The detergents and water used for cleaning may splash and dirty nearby cars, plants, and the ground.
Professional contractors will always take care to consider the surroundings during their work, but if you are doing the cleaning yourself and are not experienced, it is even more important to be mindful of the surrounding environment during the cleaning process.
Therefore, our company conducts preliminary site surveys and greetings to prevent any troubles!
If cars are nearby, we will cover them with car sheets and ensure maximum consideration!
3. Cannot be performed on severely deteriorated exterior walls
If the paint film on the exterior wall is severely deteriorated, there is a possibility that the paint film may peel off.
If the sealing material in the joints is cut, it can also cause leaks, making construction impossible.
Kakeru Koumuten Co., Ltd. is a company strong in exterior renovations, so we will thoroughly investigate the deterioration of the exterior walls and joints to confirm whether construction is possible!
As mentioned above, exterior wall cleaning (exterior wall washing) has its advantages and disadvantages. However, regular cleaning can maintain the cleanliness of the building’s appearance and enhance its durability, so we recommend doing it at the appropriate time!
We also offer carport cleaning and exterior cleaning!

Kakeru Koumuten Co., Ltd. can perform not only exterior wall cleaning but also carport and exterior cleaning!
For example, if you are someone who thinks, “It’s not time for exterior wall painting yet, but I would like to request just exterior washing and exterior cleaning..” this plan is recommended for you.
One reason why the costs for roof and exterior wall painting can add up is that “scaffolding must be set up.” However, with Kakeru Koumuten’s exterior wall cleaning (exterior wall washing), scaffolding is not required, so there are no scaffolding costs!!
Of course, partial cleaning such as exterior wall cleaning only, cleaning of one side of the exterior wall only, or exterior cleaning only is also very welcome!
On-site surveys and estimates are free, so please feel free to consult with Kakeru Koumuten Co., Ltd.!

Leave your exterior wall cleaning in Suginami-ku, Tokyo to Kakeru Koumuten!
Our company is based in Aoba-ku, Yokohama, and has extensive experience in cleaning and washing exteriors and outer structures in Kanagawa, Tokyo, Chiba, Saitama, and Shizuoka.
In cases where the building is relatively new or if there are only surface stains, cleaning (washing) alone can often restore the appearance without the need for painting or replacement.
Additionally, one of the benefits of cleaning is that it can be done at a lower cost compared to painting or replacement work.
If dirt and discoloration are left unattended, there is a possibility that no matter how strong the chemicals used, the stains may become impossible to remove, so we recommend early cleaning.
Moreover, there are various types of chemicals, and using inappropriate ones for the substrate can lead to discoloration or fading, which can actually lower the aesthetic appeal.
Kakeru Koumuten has rich experience in cleaning and washing numerous exteriors and outer structures.
“I want to remove moss from the exterior wall,” “I just want to know the estimate,” “I want to know if this stain can be removed,” if you have any concerns or questions, please feel free to contact us!
