Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Preparation
If there are plants or vehicles nearby, we will cover them before starting the cleaning! In this case, we covered the nearby plants of the neighbor!
2. Exterior Wall Cleaning (Exterior Wall Cleaning)
We will spray the special cleaning solution from the top down using a machine that mixes the detergent and a special extendable brush!
Water and detergent are sprayed from the tip of the special brush, allowing us to reach even three-story buildings! As shown in the photos above, we will also clean the rain gutters and piping!
In exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes we use are specially designed to clean gently, allowing us to remove dirt without damaging the exterior walls.
Since we only use electric machines, there is no loud noise or disturbance during the work!
The detergents we use 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!
※ Detergents that are strong against moss can harm or kill plants and trees if they splash, so caution is necessary!
Even if we cannot use a moss-resistant detergent, cleaning is still possible, so please rest assured!
We will thoroughly remove the blackening and moss from the exterior walls!
4. Water Washing
After completing the detergent washing of the entire exterior wall, we will proceed to rinse with water from the top down.
We will rinse carefully to ensure no detergent is left behind!
We will thoroughly wash away the detergent!
The exterior wall we cleaned this time had noticeable blackening, but after performing the exterior wall cleaning, the blackening was beautifully removed, resulting in a brighter overall impression!

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 sense of cleanliness and has a beautiful appearance
As time passes, dirt, mold, and moss tend to accumulate on 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, when the exterior of the building looks beautiful, the surrounding environment also appears brighter and cleaner.
In addition, 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 painting or high-pressure washing!
3. Short Construction Period
Unlike high-pressure washing or exterior painting, exterior wall cleaning can generally be completed in just 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 Incurred
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 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 us!
2. Consideration for 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 can splash, potentially dirtying nearby cars, plants, and the ground.
Professional contractors will always consider the surroundings during their work, but if you are doing the cleaning yourself and are inexperienced, 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 Performed on Severely Deteriorated Exterior Walls
Exterior walls with severely deteriorated paint film may have the paint film peeled off.
If the sealing material in the joints is cut, it can also lead to leaks, making it impossible to perform the work.
Kakeru Koumuten Co., Ltd. is strong in exterior renovations, so we will thoroughly investigate the condition of the exterior walls and joints to confirm whether work can be performed!
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 right 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 thinking, “It’s not the right time for exterior wall painting, but I would like to request exterior wall washing and exterior cleaning…” we have a plan that is perfect 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!!
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!

Leave Exterior Wall Cleaning in Hino City, Tokyo to Kakeru Koumuten!
Our company has extensive experience in cleaning and washing exterior walls and exteriors in Tokyo, including Hino City.
If the building is relatively new or if the exterior wall is only dirty, often cleaning (washing) alone can restore its 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 stains 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 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.
