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 if 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 it yourself with a brush or sponge using a household cleaning machine, but it becomes quite difficult for the second or third floors.
Are you facing any of these issues with exterior wall dirt?
“It’s been 5 years since I painted, and while it’s not time for a repaint, I’m concerned about one area that looks 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 cleaning…?”
“I’m worried that the detergent will discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning so popular in Minato-ku?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Minato-ku!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs significant 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 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 splash onto them, so caution is necessary! However, even if a strong moss detergent cannot be used, cleaning is still possible, so 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 directly spraying water with a hose!
The detergent used also has very little odor.
The sound of the machinery used is relatively quiet and electric.
That said, if the building is close, there may still be some inconvenience, so we always make sure to 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 a typical house 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 photos of the work, and we will send the photos 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)
・Concrete surfaces (such as parking lot concrete)
・Carports
・Roofs and solar panels (there may be cases where this is not possible)
If you have any 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 we will visit to greet the neighbors.
We will confirm that the work can be carried out without issues on the cleaning day during our pre-construction visit.
Point 7 Estimates can be provided using photos and drawings!
We can communicate via LINE or email, and provide estimates based on photos and drawings (floor plans and elevation drawings)!
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” during exterior wall cleaning!
Caution Point 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 Point 2 Some stains may not come off…
Stains from years of neglect, such as darkening or rain streaks, may not come off even after cleaning.
In particular, rain streaks and darkening on painted walls like Jolly Pat finish are difficult to completely remove.
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 with the use of specialized chemicals, some streaks from rain may remain on painted walls like Jolly Pat finish, so caution is necessary.
Depending on sunlight and location, it is recommended to clean the walls every 3 to 5 years without leaving dirt!
Caution Point 3 If the joints are severely deteriorated
If the joints of the siding exterior walls are severely deteriorated, it may lead to leaks, and therefore, we may not be able to carry out the work.
Note 4 There may be cases where construction is not possible due to the structure of the building.
It may be difficult to carry out 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 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!
