Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Preparation
If there are plants or cars nearby, we will cover them before starting the cleaning!
2. Exterior Wall Cleaning (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 special extendable brush!
The tip of the special brush sprays water and detergent, allowing us to reach even three-story buildings! As shown in the photos above, we will also clean the rain gutters and piping!
In our exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes we use are specially designed to clean gently, ensuring that the exterior walls are not scratched while removing dirt.
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 greenery 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 application for 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 away the detergent!
The exterior wall we cleaned this time had noticeable moss on the rain gutters and exterior walls, but after performing the exterior wall cleaning, the moss and blackening were beautifully removed, resulting in a brighter overall impression!
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, we will introduce the advantages and disadvantages!
Advantages of Exterior Wall Cleaning
First, let’s discuss the advantages of exterior wall cleaning!
1. The building maintains a sense of cleanliness and has a beautiful appearance
Over time, dirt, mold, and moss can easily accumulate on exterior walls, but regular cleaning can remove these contaminants. By performing exterior wall cleaning, the entire building will have a sense of cleanliness and a beautiful appearance.
Furthermore, by enhancing the appearance of the building, the surrounding environment will also appear brighter and cleaner.
Unlike high-pressure washing, exterior 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 (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 (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 your 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 the surrounding environment. The detergents and water used for cleaning can splash, potentially dirtying nearby cars, plants, and the ground.
While professional contractors will always take surrounding considerations into account, 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 on-site surveys and greetings to prevent any troubles!
If vehicles 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
Walls with severely deteriorated paint may have the paint film stripped away.
If the sealing material in the joints is damaged, it can also lead to leaks, making it impossible to perform the work.
Kakeru Koumuten is a company strong in exterior renovations, so we will thoroughly investigate the condition of the walls and joints to confirm whether the work can be performed!
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 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 exterior structures!
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 structure cleaning…” this plan is highly recommended for you.
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!!
Of course, partial cleaning such as exterior wall cleaning only, cleaning of one side of the exterior wall only, or exterior structure 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 Odawara City to Kakeru Koumuten!
Our company is based in Aoba-ku, Yokohama, Kanagawa Prefecture, and we have extensive experience in cleaning and washing exterior walls and exteriors throughout Kanagawa Prefecture, including Odawara City.
In cases where 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 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.
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!
