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. Exterior Wall Cleaning (Exterior Wall Cleaning)

We will spray the specialized cleaning solution from the top down using a machine that mixes the detergent and a special extendable brush!
The nozzle of the special brush sprays water and detergent, reaching even three-story buildings! Rain gutters and pipes will also be cleaned!
For exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes used are specialized and clean gently, removing dirt without damaging the exterior wall. Since we only use electric machines, there will be no loud noises or disturbances during the work!
The detergent used is safe and will not discolor the sashes or exterior walls!
We also differentiate the detergents used based on the type of dirt, such as rain stains, 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 the black stains and moss from the exterior walls!
3. Rinsing
After completing the cleaning with detergent on the entire exterior wall, we will rinse it with water from the top down.
We will rinse carefully 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, but after the exterior wall cleaning, the black stains were beautifully removed, giving it a brighter overall impression!
Thank you for entrusting us with the work at 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 clean appearance and looks beautiful
Over time, 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, a beautiful exterior enhances the surrounding environment, making it look 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 appearance 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 is generally completed in one day!
4. No Noise
Since we only use electric machines, the absence of loud noises or disturbances 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 are 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 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 us!
2. Consideration for Surroundings is Necessary
During the cleaning process, there is a possibility of affecting the building and the surrounding environment. The detergents and water used for cleaning may splash and dirty nearby vehicles, plants, or the ground.
While professional contractors will ensure consideration for the surroundings during their work, if you are doing the cleaning yourself without experience, 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 there are vehicles nearby, we will cover them with car sheets, ensuring maximum consideration!
3. Cannot be Performed on Severely Deteriorated Exterior Walls
If the paint film on the exterior wall is severely deteriorated, it may peel off during cleaning.
If the sealing material in the joints is cut, it may cause leaks, making it impossible to perform the work.
Kakeru Koumuten Co., Ltd. is strong in exterior renovations, so we will thoroughly investigate the condition of the exterior walls and joints to confirm whether the work can be performed!
As you can see, exterior wall cleaning has both advantages and disadvantages. However, regular cleaning helps maintain the cleanliness of the building’s exterior and enhances durability, so we recommend performing it at the appropriate timing!
We also offer Carport 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 thinking, “It’s not time for exterior wall painting yet, but I would like to request exterior wall cleaning and exterior cleaning…“, this is a recommended plan for you.
One reason why construction costs for roof and exterior wall painting can increase is the need to “set up scaffolding.” However, with Kakeru Koumuten’s exterior wall cleaning, there are no scaffolding costs!
Of course, we welcome partial cleaning such as exterior wall cleaning only, one side of the exterior wall cleaning only, or exterior cleaning only!
Site surveys and estimates are free, so please feel free to consult Kakeru Koumuten Co., Ltd.!

Leave Exterior Wall Cleaning in Tama City, Tokyo to Kakeru Koumuten Co., Ltd.!
Our company is based in Machida City, Tokyo, and we have many successful cleaning and washing projects for exteriors in nearby Tama City.
If the building is relatively new or if the only issue is dirt on the exterior walls, cleaning alone can often restore its appearance without the need for painting or replacement.
Additionally, cleaning is one of the advantages of being able to keep costs lower compared to painting or replacement work.
If dirt and black stains are left unattended, no matter how strong the chemicals used, they may become impossible to remove, so we recommend cleaning as soon as possible.
Also, 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.
Kakeru Koumuten Co., Ltd. has extensive experience in cleaning and washing exteriors.
Our company specializes in exterior renovations, so we are happy to assist with not only cleaning but also exterior wall painting, exterior painting, waterproofing work, and other partial painting jobs.
If you have any concerns such as “I want to remove moss from the exterior wall,” “I just want to know the estimate,” or “I want to know if this stain can be removed,” please feel free to contact us!
We also have pricing plans for exterior wall and exterior work, so please take a look if you are interested!
