We welcome comparative estimates!
What is exterior wall cleaning…
Exterior wall cleaning is a method of regular maintenance to keep the building’s beautiful appearance and prolong the life of the exterior materials.
As shown 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 structure.
Typically, when the exterior wall darkens or moss grows, the common options are “exterior wall painting” or “high-pressure washing of the exterior wall”.
If it’s 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 becomes quite difficult for the second or third floors.
Are you facing these issues with dirty exterior walls?
“I painted 5 years ago, and while it’s not in need of painting, I’m concerned about one area that’s dirty…”
“Painting is expensive, so I don’t plan 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 with just washing…?”
“I’m worried that the detergent might discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior wall cleaning can solve them!
Why is Kakeru Koumuten’s exterior wall cleaning popular in Arakawa-ku?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior wall cleaning well-received in Arakawa-ku!
Point 1 Overwhelmingly low cost
Typically, exterior wall painting and high-pressure washing require scaffolding, which inevitably incurs high costs.
Kakeru Koumuten’s exterior wall cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior walls at about 1/10 the cost of exterior wall painting!
Point 2 Cleaning without damaging the exterior walls!
We use gentle water pressure instead of high pressure for washing. The brushes we use are specially designed to 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!
※Detergents that are strong against moss can harm or kill plants if they drift onto them, so caution is necessary! 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 neighbors!
By using a special brush to apply a gentle water flow, it is less likely to scatter than spraying directly with a hose!
The detergent used also has very little odor.
The machine used is electric and relatively quiet.
That said, if the building is close, there may still be some inconvenience, so we always greet the neighbors before starting the work.
If cars are 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 basically done outdoors, cleaning can be done even if you are not at home!
Of course, we will take detailed photos of the work and send them to you later.
Point 5 Can clean areas other than the exterior all at once!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Ground (concrete parking lots, etc.)
・Carports
・Roofs and solar panels (there may be cases where this is not possible.)
If there are other areas of concern, please feel free to consult with us!
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 confirm on-site before the cleaning day to ensure that the work can proceed without 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) via LINE or email!
In cases where it is difficult to estimate based on photos or drawings, we will visit the site for an on-site survey.
Estimates will be sent within 1 to 2 business days after receiving the photos or drawings!
What should you be aware of when cleaning exterior walls?
Next, we will explain the “5 points to be cautious about” during exterior wall cleaning!
Caution 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar walls with many cracks may not be cleanable.
This is to prevent leaks and peeling of the paint film.
Caution 2 Some stains may not come off…
Black stains and rain streaks that have been left for many years may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jolly Pat finish.
If you try to forcibly remove black stains or rain streaks from Jolly Pat exterior walls, it may cause discoloration or damage, so we will use special agents to clean gently as much as possible. 
As shown above, even when using special chemicals, some rain streaks may remain on Jolly Pat finish and other plastered exterior walls, so caution is necessary.
Depending on sunlight and location, it is recommended to clean every 3 to 5 years without leaving dirt!
Caution 3 If the joints are severely deteriorated
If the joints of the siding exterior wall are severely deteriorated, it may lead to water leakage, and there may be cases where construction cannot be performed.
Note 4 There may be cases where construction is not possible due to the structure of the building.
It may be difficult to perform construction in areas such as above eaves, above bay windows, or extremely narrow locations.
We will confirm this during the inspection.
Note 5 We will need to use electricity and water!
During cleaning, 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!
