What is exterior wall cleaning…
Exterior wall cleaning is one 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.
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 is within reach, such as around the first floor, it may be possible to clean using a brush or sponge with a household cleaning machine, but it becomes 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 need of painting, I’m concerned about one side being dirty…”
“Painting is expensive, so I don’t plan to do it yet, but I want to clean the exterior while keeping costs down…”
“It’s a three-story building, but can it be cleaned without scaffolding…?”
“Will this dirt come off with just washing…?”
“I’m worried that the detergent might discolor the exterior walls.”
If you have such concerns, Kakeru Koumuten’s exterior wall cleaning can solve them!
Why is Kakeru Koumuten’s exterior wall cleaning popular in Kiyose City?
Here are the “7 points” that make Kakeru Koumuten’s exterior wall cleaning well-received in Kiyose City!
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 cleaning. The brushes used are specialized and clean gently, removing dirt without damaging the exterior walls.
The detergents used are formulated to avoid 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!
*Please note that detergents strong against moss can harm or kill plants if they splash on them, so caution is necessary! However, even if a moss-resistant detergent cannot be used, cleaning is still possible, so please rest assured!
Point 3 Can clean exterior walls with relatively little inconvenience to neighbors!
Since we use a special brush to apply a gentle water flow, it is less likely to scatter compared to using a hose directly!
The detergent used also has very little odor.
The machine noise is relatively quiet as it is electric.
That said, if the building is close by, there may still be some inconvenience, so we always make sure to greet the neighbors before the work begins.
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 home!
Of course, we will take detailed construction photos and send them to you later.
Point 5 Cleaning can be done for areas other than the exterior walls as well!
In addition to exterior walls, 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.)
Please consult us about any other areas you are concerned about!
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 communicate via LINE or email, and provide estimates based on photos and drawings (floor plans and elevation drawings)!
In some cases, it may be difficult to provide an estimate based on photos or drawings, and in such cases, 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 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…
Stains from years of neglect, such as darkening or rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from textured wall finishes like Jolly Pat.
If you try to forcibly remove darkening or rain streaks from Jolly Pat walls, it may lead to discoloration or damage, so we will use specialized agents to clean gently as much as possible. 
As shown above, even when using specialized chemicals, some rain streaks may remain on textured wall finishes like Jolly Pat, 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 unattended!
Caution 3 When the joints are severely deteriorated
If the joints of the siding exterior walls are severely deteriorated, it may lead to leaks, and there may be cases where we cannot 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 spots.
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!

By repeating the application of the cleaning agent and washing, we gradually remove the dark stains!
