Exterior Wall Cleaning (Exterior Wall Cleaning) Procedure

1. Preparation

If there are plants or vehicles nearby, we will prepare the area 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 specialized extendable brush!

The nozzle of the specialized brush sprays water and detergent, reaching even three-story buildings! Rain gutters and pipes will also be cleaned simultaneously! 

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 detergents used 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, 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 black stains and moss from the exterior walls!

3. Rinsing

After completing the cleaning with detergent on the entire exterior wall, we will rinse 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 black stains, but after performing the exterior wall cleaning, the black stains were beautifully removed, giving it a brighter overall impression!

Thank you for entrusting us with the project at Kakeru Koumuten Co., Ltd.!

What are the advantages and disadvantages of exterior wall cleaning?

Exterior wall cleaning is a highly cost-effective maintenance method to restore the aesthetics 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 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.

Moreover, with an improved exterior appearance, the surrounding environment will also look brighter and cleaner.
Additionally, unlike high-pressure washing, exterior wall cleaning can be done without damaging the exterior walls.

2. Low cost

Since cleaning can be done without setting up 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 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 involved

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

If you hire a professional contractor, 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 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 splash and dirty nearby cars, plants, or the ground.

While professional contractors will always consider the surroundings during their work, if you are doing the cleaning yourself, 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 there are cars nearby, we will protect them with car covers and take maximum care!

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 damaged, it may cause leaks, making cleaning impossible.
Kakeru Koumuten Co., Ltd. specializes in exterior renovations, so we will thoroughly investigate the condition of the exterior walls and joints to confirm whether cleaning can be performed!

As you can see, exterior wall cleaning has both advantages and disadvantages. However, regular cleaning can maintain the cleanliness of the building’s exterior and enhance its durability, so we recommend performing it at the appropriate timing!

Carport Cleaning and Exterior Cleaning Services Available!

Kakeru Koumuten Co., Ltd. not only offers exterior wall cleaning but also provides cleaning services for carports and exteriors!

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 only..” this plan is recommended for you.

One reason why construction costs for roof and exterior wall painting can become high is that “scaffolding needs to be set up.” However, with Kakeru Koumuten’s exterior wall cleaning, there is no need for scaffolding, so there are no scaffolding costs!

Of course, we welcome partial cleaning such as exterior wall cleaning only, cleaning one side of the exterior wall, 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 achievements in cleaning and washing 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 aesthetics without the need for painting or replacement.

Additionally, cleaning is generally more cost-effective compared to painting or replacement work, which is another advantage.

If dirt and black stains are left unattended, no matter how strong the chemicals used are, they may become impossible to remove, so we recommend early cleaning.

Also, there are various types of chemicals, and using the wrong ones for the substrate can lead to discoloration or fading, which can further diminish aesthetics.

Kakeru Koumuten Co., Ltd. has extensive experience in cleaning and washing various exteriors.

We specialize 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 services.

If you have any concerns such as “I want to remove moss from the exterior walls,” “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!
