We welcome comparative estimates!
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 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 structural factors.
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 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 becomes quite difficult for the second or third floors.
Do you have these concerns about exterior wall dirt?
“I painted 5 years ago, and while it’s not time for a repaint, 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 will 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 Bunkyo-ku?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior cleaning well-received in Bunkyo-ku!
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 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!
*Please note that detergents strong against moss can harm or kill plants if they come into contact, so caution is necessary! Even if a moss-resistant detergent cannot be used, cleaning is still possible, so rest assured!
Point 3 Can clean the exterior without causing much trouble 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 is electric and relatively quiet.
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 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 can be done for areas other than the exterior!
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 (some restrictions may apply)
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 confirm that the work can proceed smoothly on the day of cleaning.
Point 7 Estimates can be provided using photos or drawings!
We can communicate via LINE or email, and provide estimates based on photos or drawings (floor plans and elevation drawings)!
In cases where 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 aware of when cleaning exterior walls?
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 or rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from painted walls like Jolly Pat finishes.
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 finishes, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean 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 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 spaces.
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!
