Exterior Wall Cleaning (Exterior Wall Cleaning) Construction Procedure
1. Exterior Wall Cleaning (Exterior Wall Cleaning)
Using a machine to mix the detergent and a special extendable brush, we spray the exterior wall cleaning detergent from the top down!
The nozzle of the special brush sprays water and detergent, reaching even a 3-story building!
For exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes used are specially designed to clean gently, removing dirt without damaging the exterior wall.
Since we only use electric machines, there will be no loud noises or disturbances during construction!
The detergent used 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 stains, blackening, and moss!
* Detergents that are strong against moss can harm or kill plants 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 thoroughly remove black stains and moss from exterior walls!
2. Water Washing


After completing the detergent cleaning of the entire exterior wall, we proceed to rinse with water from the top down.
We carefully rinse to ensure no detergent is left behind!
The green moss has been beautifully removed!
We thoroughly rinse out the detergent.
After the exterior wall cleaning, our customers were extremely satisfied!
Thank you for trusting Kakeru Koumuten!

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 exterior walls, but regular cleaning can remove these stains. By performing exterior wall cleaning, the entire building maintains a clean and beautiful appearance.
Furthermore, as the building’s exterior 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 aesthetic appeal 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 is generally 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, exterior wall cleaning also has its disadvantages!
1. It incurs a certain cost
First, it is important to note that there are certain costs associated with cleaning.
If you hire a professional contractor, the cleaning work, the detergents used, and painting will incur certain 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, 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 take surrounding considerations into account 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 when carrying out cleaning tasks.
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 providing the utmost consideration!
3. Work Cannot Be Done on Severely Deteriorated Exterior Walls
Exterior walls with severely deteriorated paint may risk peeling off the paint layer.
If the sealing material in the joints is cut, it can also lead to leaks, making it impossible to proceed with the work.
Kakeru Koumuten Co., Ltd. specializes in exterior renovations, so we will thoroughly investigate the condition of the exterior walls and joints to confirm whether work can be done!
As mentioned above, exterior wall cleaning (exterior wall washing) has both 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 timing!
We Also Offer Carport and Exterior Cleaning!

Kakeru Koumuten Co., Ltd. can provide not only exterior wall cleaning but also carport and exterior cleaning!
For example, if you are thinking, “It’s not time for exterior painting yet, but I would like to request exterior wall cleaning and exterior cleaning…” we have a recommended plan for you.
One reason why the cost of roofing and exterior painting work can add up is that “scaffolding must be set up.” However, at Kakeru Koumuten Co., Ltd., our exterior cleaning (exterior washing) does not require scaffolding, so there are no scaffolding costs!!
Of course, we also welcome partial cleaning such as exterior cleaning only, cleaning of just one side of the exterior, or exterior structure cleaning only!
The on-site inspection and estimate are free, so please feel free to consult with Kakeru Koumuten Co., Ltd.!

Leave Your Exterior Wall Cleaning in Kohoku-ku, Yokohama to Kakeru Koumuten!
Our company has extensive experience in cleaning and washing exterior walls and exteriors in Kohoku-ku.
If the building is relatively new or if the exterior walls are only dirty, often cleaning (washing) alone can 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 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 decrease 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 painting projects, even if it’s just partial painting.
“I just want to know the estimate for now” or “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!
