If you are looking for an exterior wall cleaning contractor in
Mitaka City, Tokyo, contact Kakeru Koumuten
Kakeru Koumuten is engaged in many exterior wall cleaning and washing projects in Mitaka City, Tokyo!
The two major benefits of exterior wall cleaning are as follows!
“No need for temporary scaffolding”
“Enhancing the appearance of the building at a lower cost compared to exterior wall painting”
That said, exterior wall cleaning is still a relatively unknown service.
In this article, we will also introduce case studies, benefits, precautions, and costs of exterior wall cleaning in Mitaka City!
Estimates and consultations are free!
We welcome competitive quotes!
What is exterior wall cleaning…
Exterior wall cleaning is one method of regular maintenance to keep the building’s appearance clean and to prolong the life of the exterior materials.
As seen in the photo above, even when the paint film on the exterior wall is in good condition, rain streaks, darkening, and moss can occur due to sunlight and structural factors.
When the exterior wall becomes dark or moss grows, the common options were “exterior wall painting” or “high-pressure washing of the exterior wall”.
If it is within reach, such as around the first floor, it may be possible to clean using a household cleaning machine with brushes or sponges as a DIY project, but it would be quite difficult for the second or third floors.
Are you facing these concerns with dirty exterior walls?
“I painted 5 years ago, and while it’s not in bad shape, I’m concerned about one area that’s dirty…”
“Painting is expensive, so I’m not planning to do it yet, but I want to clean the exterior at a lower cost…”
“It’s a three-story building, but is it possible to clean without scaffolding…?”
“Will this dirt come off just with cleaning…?”
“I’m worried that the detergent might discolor the exterior walls.”
For those with such concerns, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning popular in Mitaka City?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning well-received in Mitaka City!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs high costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior at about 1/10 the cost of exterior painting!
Point 2 Cleaning without damaging the exterior!
We use gentle water pressure instead of high pressure for cleaning. The brushes used are specialized and clean gently, removing dirt without damaging the exterior walls.
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, blackening, and moss!
※Caution is necessary as detergents strong against moss can harm or kill plants if they splash on them! However, even if we cannot use a moss-resistant detergent, cleaning is still possible, so please rest assured!
Point 3 Can clean the exterior without causing much inconvenience to the neighbors!
By using a special brush to apply a gentle water flow, it is less likely to scatter than using a hose directly!
The detergent used also has little to no odor.
The machine used operates quietly as it is electric.
However, if the building is close by, there may still be some inconvenience, so we will definitely greet the neighbors before the work begins.
If there are cars nearby, we will protect them with car seat covers!
Point 4 Short construction period!!
For regular single-family home exterior cleaning, it often can be completed in just one day even for full cleaning!
Since the work is generally done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed construction photos and send them to you later.
Point 5 Cleaning of areas other than the exterior is also possible!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (like parking lots)
・Carports
・Roofs and solar panels (there may be cases where this is not possible.)
Please feel free to consult us about any other areas of concern!
Point 6 We will conduct a site survey before construction!
Before construction, we will check the condition of the exterior walls and joints, and greet the neighbors.
We will also check before the cleaning day to ensure that the work can proceed without any issues.
Point 7 Estimates can be provided using photos or drawings!
We can provide estimates based on photos and drawings (floor plans and elevation drawings) exchanged via LINE or email!
However, if it is difficult to provide an estimate based on photos or drawings, we will visit the site for an inspection.
Estimates will be sent within 1 to 2 business days after receiving the photos or drawings!
What should you be cautious about during exterior wall cleaning?
Next, we will explain the “5 points to be cautious about” when it comes to exterior wall cleaning!
Caution 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar walls with many cracks may not be able to be cleaned.
This is to prevent leaks and peeling of the paint film.
Caution 2 Some stains may not come off…
Stains from years of neglect, such as darkening and rain streaks, may not come off even after cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from painted walls like Jolly Pat finish.
If you try to forcibly remove darkening or rain streaks from Jolly Pat walls, it may cause discoloration or damage, so we will use specialized agents to clean gently as much as possible. 
As shown above, even when using specialized chemicals on painted walls like Jolly Pat finish, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean the exterior walls every 3 to 5 years without leaving dirt!
Caution 3 Severe deterioration of joints
If the joints of the siding exterior are severely deteriorated, it may lead to leaks, and therefore, we may not be able to perform the work.
Note 4 There may be cases where work cannot be performed due to the structure of the building.
It may be difficult to work in areas such as above eaves, above bay windows, or extremely narrow spaces.
We will confirm this during the inspection.
Note 5 We will need to use electricity and water!
During the cleaning process, we will borrow electricity and water.
If there is no electricity or water outside, additional costs may be incurred, but we can also provide a generator or tank!
