Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Preparation
If there are plants or vehicles nearby, we will take precautions before starting the cleaning!
2. Exterior Wall Cleaning (Exterior Wall Cleaning)
Using a machine to mix the detergent and a special extendable brush, we will spray the dedicated cleaning detergent from the top down!
The nozzle of the special brush sprays water and detergent, reaching even three-story buildings! As shown in the photo above, we will also clean the rain gutters and piping!
For exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes used are specially designed to clean gently, ensuring that the exterior walls are not scratched while removing dirt.
Since we only use electric machines, there will be no loud noises or disturbances during the work!
The detergents used are formulated to prevent discoloration of the sashes and exterior walls!
We also differentiate the detergents used based on the types of dirt, such as rain stains, blackening, and moss!
*Caution is needed as detergents that are strong against moss can harm or kill nearby plants!
Even if we cannot use moss-resistant detergents, cleaning is still possible, so please rest assured!
We thoroughly remove black stains and moss from the exterior walls!
3. Water Washing
After completing the detergent cleaning of the entire exterior wall, we will proceed with water washing from the top down.
We will rinse carefully to ensure no detergent is left behind!
We will thoroughly rinse out the detergent!
The exterior wall we cleaned this time had noticeable black stains, but after performing exterior wall cleaning, the black stains were beautifully removed, giving it a brighter overall impression!
Rain Gutter Repair Work
This time, we also performed repair work on the vertical rain gutter for our customer!
The materials used were Panasonic S30!
Thank you for trusting Kakeru Koumuten Co., Ltd.!

What are the Advantages and Disadvantages of Exterior Wall Cleaning?
Exterior wall cleaning is a cost-effective maintenance method that restores the aesthetic appeal of a building 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 clean appearance and looks beautiful
Over time, dirt, mold, and moss can easily accumulate on the exterior walls, but regular cleaning can remove these stains. By performing exterior wall cleaning, the entire building will have a clean and beautiful appearance.
Furthermore, as the exterior of the building becomes more attractive, 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 the appearance at a lower cost compared to exterior painting and high-pressure washing!
3. Short construction period
Unlike high-pressure washing or exterior painting, exterior cleaning (washing) can basically 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 cleaning!
Disadvantages of exterior cleaning
On the other hand, there are also disadvantages to exterior cleaning (washing)!
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 painting will all incur costs, so it is necessary to plan a budget in advance.
Kakeru Koumuten Co., Ltd. offers free estimates, so please feel free to consult us!
2. Consideration for the surroundings is necessary
During the cleaning process, there may be impacts on the building and the surrounding environment. The detergents and water used for cleaning may splash, potentially dirtying nearby cars, plants, and the ground.
Professional contractors will always consider the surroundings while working, 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 troubles!
If cars are nearby, we will protect them with car seat covers, and we are committed to taking maximum care!
3. Cannot be applied to severely deteriorated exteriors
If the paint film on the exterior is severely deteriorated, it may peel off during cleaning.
If the sealing material in the joints is cut, it can also cause leaks, making it impossible to proceed with the work.
Kakeru Koumuten Co., Ltd. is a company strong in exterior renovations, so we will thoroughly investigate the condition of the exterior and joints to confirm whether work can be done!
As you can see, exterior cleaning (washing) has both advantages and disadvantages. However, regular cleaning can maintain the cleanliness of the building’s appearance and enhance durability, so it is recommended to perform it at appropriate times!
We also offer carport cleaning and exterior cleaning!

Kakeru Koumuten Co., Ltd. offers not only exterior wall cleaning but also carport and exterior cleaning services!
For example, if you are thinking, “It’s not the right time for exterior wall painting, but I would like to request exterior wall cleaning and exterior cleaning…” this plan is highly recommended for you.
One reason why the costs for roof and exterior wall painting can add up is that “scaffolding needs to be set up.” However, with Kakeru Koumuten’s exterior wall cleaning (exterior wall washing), there is no need for scaffolding, so you won’t incur 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!
Since on-site surveys and estimates are free, please feel free to consult with Kakeru Koumuten!

Leave Your Exterior Wall Cleaning in Tama-ku, Kawasaki to Kakeru Koumuten!
Our company has extensive experience in cleaning and washing exterior walls and exteriors within Kawasaki City.
If the building is relatively new or if there are only surface stains, cleaning (washing) alone can often restore the aesthetic 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 unsuitable 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 exterior walls and exteriors.
Our company specializes in exterior renovations, so we are happy to assist not only with cleaning but also with exterior wall painting, exterior painting, waterproofing work, and other partial painting projects.
