Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Exterior Wall Cleaning (Exterior Wall Cleaning)
Using a machine to mix the detergent and a special extendable brush, we apply the exterior wall cleaning detergent from the top down!
The tip of the special brush sprays water and detergent, reaching even 3-story buildings!
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 is no loud noise or disturbance during the work!
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 can’t use a moss-resistant detergent, cleaning is still possible, so please rest assured!
We thoroughly remove blackening and moss from the exterior walls!
2. Water Washing

After completing the detergent wash 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!
The green moss has been beautifully removed!
We will thoroughly rinse out the detergent!
Concrete Floor Cleaning Procedure
1. Cleaning
We will perform concrete floor cleaning using an all-purpose cleaner!
The all-purpose cleaner we use is equipped with a cleaning gun, allowing the nozzle to rotate inside the cover and perform powerful concrete floor cleaning without scattering around!
We will thoroughly wash with high-pressure cleaning!
2. Cleaning Up
We will return items that were moved for the concrete floor cleaning and properly remove any debris around the floor before finishing up!
Both the exterior wall cleaning and concrete floor cleaning were greatly appreciated by our customers!
Thank you for trusting Kakeru Koumuten!

What are the Advantages and Disadvantages of Exterior Wall Cleaning?
Exterior wall cleaning is a highly cost-effective maintenance method to restore 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 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 building’s exterior becomes more attractive, the surrounding environment will also appear 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 painting and high-pressure washing!
3. Short Construction Period
Unlike high-pressure washing or exterior painting, exterior cleaning (exterior washing) can generally be completed in just one day!
4. No Noise
Using only electric machines means that there is no loud noise or disturbance, which is another advantage of exterior cleaning!
Disadvantages of Exterior Cleaning
On the other hand, there are also disadvantages to exterior cleaning (exterior washing)!
1. Certain Costs Incurred
First, it should be noted that cleaning incurs certain costs.
If you hire a professional, the cleaning work, the detergents used, and painting will all incur costs, so it is necessary to plan a budget in advance.
Kakeru Koumuten offers free estimates, so please feel free to consult with us!
2. Consideration for Surroundings is Necessary
During the cleaning process, there may be impacts on the building and surrounding environment. The detergents and water used for cleaning can splash and potentially dirty nearby cars, plants, and the ground.
While professional contractors will always consider the surroundings during their work, 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 providing maximum consideration!
3. Not Applicable for Severely Deteriorated Exteriors
If the paint film on the exterior is severely deteriorated, there is a possibility that it may peel off.
If the sealing material in the joints is cut, it can also lead to leaks, making it unsuitable for cleaning.
Kakeru Koumuten is a company strong in exterior renovations, so we will thoroughly investigate the condition of the exterior and joints to confirm whether cleaning is possible!
As you can see, exterior cleaning (exterior washing) has both advantages and disadvantages. However, regular cleaning can maintain the cleanliness of the building’s appearance and enhance durability, so we recommend doing it at the appropriate timing!
We also offer carport cleaning and exterior cleaning!

Kakeru Koumuten Co., Ltd. not only offers exterior wall cleaning but also provides cleaning services for carports and exteriors!
For example, this plan is recommended for those who are thinking, “It’s not the right time for exterior wall painting, but I would like to request exterior wall cleaning and exterior cleaning..”
One reason why costs can add up for roof and exterior wall painting projects 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 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!

Leave Your Exterior Wall Cleaning in Aoba-ku, Yokohama to Kakeru Koumuten!
Our company has extensive experience in cleaning and washing exterior walls and exteriors in Aoba-ku.
If the building is relatively new or if there are only surface stains, cleaning (washing) alone can often 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 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 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.
