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 a special cleaning detergent 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, reaching even three-story buildings! Rain gutters and piping will also be cleaned together! 

For exterior wall cleaning, we use gentle water pressure instead of high-pressure washing. The brushes used are special brushes that 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 will not discolor the sashes or exterior walls!
We will 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 will thoroughly remove blackening and moss from the exterior walls!

3. Water Rinse


After completing the detergent cleaning of the entire exterior wall, we will rinse with water from the top down again.
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 dark stains, but after performing the exterior wall cleaning, the dark stains were beautifully removed, giving it a brighter overall impression!

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 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 exterior of the building becomes more attractive, the surrounding environment also appears brighter and cleaner.
Additionally, 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 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. There are certain costs involved

First, it should be noted that cleaning incurs certain costs.

If you hire a professional, the cleaning work, the detergents used, and any painting done will incur 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 may scatter, potentially dirtying nearby cars, plants, and the ground.

While professional contractors always take surrounding considerations into account during their work, if you are doing the cleaning yourself and are not experienced, it is even more crucial to be mindful of the surrounding environment when carrying out cleaning tasks.

Therefore, our company conducts preliminary on-site surveys and greetings to prevent any troubles!
If vehicles are nearby, we will protect them with car covers, ensuring maximum consideration!

3. Installation Not Possible on Severely Deteriorated Exterior Walls

If the paint film on the exterior wall is severely deteriorated, it may peel off.
If the sealing material in the joints is cut, it can also cause leaks, making installation impossible.
Kakeru Koumuten is a company strong in exterior renovations, so we thoroughly investigate the condition of the exterior walls and joints to confirm whether installation is possible!

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 cleaning and exterior cleaning!

Kakeru Koumuten can perform not only exterior wall cleaning but also carport and exterior cleaning!

For example, if you are thinking, “It’s not the right time for exterior wall painting yet, but I would like to request exterior wall cleaning and exterior cleaning…” this plan is recommended for you.

One reason why construction costs for roof and exterior wall painting can add up is that “scaffolding must be set up.” However, with Kakeru Koumuten’s exterior wall cleaning (exterior wall washing), there are no scaffolding costs because scaffolding is not required!!

Of course, partial cleaning such as exterior wall cleaning only, one side of the exterior wall cleaning only, or exterior cleaning only is also very welcome!

On-site surveys and estimates are free, so please feel free to consult Kakeru Koumuten!

Leave Your Exterior Wall Cleaning in Aoba-ku, Yokohama to Kakeru Koumuten!

Since our company is based in Aoba-ku, Yokohama, we have extensive experience in cleaning and washing exterior walls and exteriors throughout Kanagawa Prefecture, including Aoba-ku, Yokohama.

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!
