Exterior Wall Washing (Exterior Wall Cleaning) Construction Procedure
1. Preparation
If there are plants or vehicles nearby, we will take precautions before starting the cleaning!
2. Exterior Wall Cleaning
We will spray a special cleaning solution for exterior walls from the top down using a machine that mixes the detergent and a specialized extendable brush!
The tip of the specialized brush sprays water and detergent, allowing us to reach 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 brush we use is specialized and cleans gently, removing dirt without damaging the exterior walls.
Since we only use electric machines, there will be no loud noises or disturbances during the work!
The detergent we use is 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 streaks, black stains, and moss!
* Detergents that are strong against moss can harm or kill nearby plants, so caution is necessary!
Even if we cannot use moss-resistant detergents, cleaning is still possible, so please rest assured!
We will thoroughly remove black stains and moss from the exterior walls!
4. Water Rinsing
After completing the cleaning with detergent on the entire exterior wall, we will rinse with water from the top down.
We will carefully rinse to ensure no detergent is left behind!
We will thoroughly wash away the detergent!
The exterior wall we cleaned this time had noticeable black stains near the slim duct, but after performing the exterior wall cleaning, the black stains were beautifully removed, giving it a brighter overall appearance!
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 beauty of a building at a low cost. Here are the advantages and disadvantages!
Advantages of Exterior Wall Cleaning
First, let’s introduce the benefits of exterior wall cleaning (exterior wall washing)!
1. The building maintains a sense of cleanliness and has a beautiful appearance
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 sense of cleanliness and a beautiful appearance.
Furthermore, as the building’s appearance becomes more attractive, the surrounding environment will also look brighter and cleaner.
Additionally, 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 (exterior wall washing) 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 a benefit of exterior wall cleaning!
Disadvantages of exterior wall cleaning
On the other hand, there are also disadvantages to exterior wall cleaning (exterior wall washing)!
1. Certain costs are involved
First, it should be noted that cleaning incurs certain costs.
If you hire a professional, the cleaning work, the detergents used, and any painting will incur costs, so it is necessary to plan your 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 impact the building or the surrounding environment. The detergents and water used for cleaning may splash, potentially dirtying nearby cars, plants, or 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 protect them with car seat covers, and we are committed to taking maximum care!
3. Cannot be performed on severely deteriorated 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 it impossible to proceed with the work.
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 the work can be carried out!
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 someone who thinks, “It’s not time for exterior wall painting yet, but I would like to request just exterior wall washing and exterior cleaning..” this plan is highly recommended for you.
One reason why the costs for roof and exterior wall painting work 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 inspections and estimates are free, so please feel free to consult with Kakeru Koumuten Co., Ltd.!

Leave Exterior Wall Cleaning in Hodogaya-ku, Yokohama to Kakeru Koumuten!
Our company is based in Aoba-ku, Yokohama, and we have extensive experience in cleaning and washing exterior walls and exteriors throughout Kanagawa Prefecture, including Hodogaya-ku, Yokohama.
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 are, 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 decrease the aesthetic appeal.
Kakeru Koumuten has a wealth of experience in cleaning and washing numerous exterior walls and exteriors.
We specialize 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.
“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!
We also have pricing plans for exterior wall and exterior work available, so please take a look if you’re interested!
