Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure
1. Preparation
If there are plants or vehicles nearby, we will cover them before starting the cleaning!
2. Application of Special Detergent
We will apply a special detergent for Jolly Pat using a roller or brush before proceeding with the cleaning!
Dirt that has adhered to the Jolly Pat is difficult to remove, so we will apply the special detergent and clean repeatedly until it gradually becomes clean.
3. Exterior Wall Cleaning (Exterior Wall Cleaning)
Using a machine to mix the detergent and a special extendable brush, we will spray the exterior wall cleaning detergent from the top down!
The nozzle of the special brush sprays water and detergent, allowing us to reach even three-story buildings! As shown in the above photos, we will also clean the rain gutters and piping!
It is difficult to completely remove rain stains from Jollypat, and trying to forcefully remove the dirt may cause discoloration or damage to the Jollypat, so there may be some residual rain stains as shown in the photo!
Exterior wall cleaning is done not with high-pressure washing, but with gentle water pressure. The brushes used are specialized brushes that clean gently, allowing us to remove dirt without scratching the exterior wall.
Since we only use electric machines, there is no loud noise or disturbance during the work!
The detergents used are formulated to avoid discoloration of the sashes and exterior walls!
We also differentiate the detergents used depending on the type of dirt, such as rain streaks, black stains, 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 black stains and moss from the exterior walls!
4. Water Washing


After completing the cleaning with detergent on 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 rinse out the detergent!
The exterior wall we cleaned this time had noticeable black stains, but after performing the exterior wall cleaning, the black stains were beautifully removed, giving it 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 high-cost-performance 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 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 building’s exterior looks beautiful, 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 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 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, the cleaning work, the detergents used, and any painting will incur costs, so it is necessary to plan a budget in advance.
Kakeru Koumuten Co., Ltd. offers free estimates, so please feel free to consult with us!
2. Consideration for Surroundings is Necessary
During the cleaning process, it is possible that the work may affect the building or the surrounding environment. The detergents and water used for cleaning may splash, potentially dirtying 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 troubles!
If cars are nearby, we will cover them with car seats and ensure maximum consideration!
3. Cannot Be Performed on Severely Deteriorated Walls
Exterior walls with severely deteriorated paint may risk peeling off the coating.
If the sealing material in the joints is cut, it may also cause leaks, making it impossible to perform 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 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 appropriate time!
We also offer carport cleaning and exterior cleaning!

Kakeru Koumuten Co., Ltd. not only provides exterior wall cleaning but also offers carport and exterior cleaning services!
For example, if you are thinking, “It’s not time for exterior painting yet, but I would like to request exterior 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, so you won’t incur 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!

If your building is relatively new or if the only issue is dirt on the exterior walls, 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 black 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 the wrong ones for the substrate can lead to discoloration or fading, which can actually decrease the aesthetic appeal.
