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 structural factors.
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 might 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 these issues with dirty exterior walls?
“I painted 5 years ago, 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 at a lower cost…”
“It’s a three-story building, but can it be cleaned 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 Edogawa-ku?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Edogawa-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!
※Detergents that are strong against moss can harm or kill plants if they splash on them, so caution is necessary! 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 neighbors!
By using a special brush with a gentle water flow, it is less likely to splash compared to using a hose directly!
The detergent used has little to no odor, and the machines used are relatively quiet.
That said, if the building is close, there may still be some inconvenience, so we always 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 a typical 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 photos of the work, and we will send the pictures 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)
・Ground (concrete parking lots, etc.)
・Carports
・Roofs and solar panels (there may be cases where this is not possible.)
If you have 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 visit the site before the cleaning day to confirm that the work can be carried out 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) through LINE or email!
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” during exterior wall cleaning!
Caution 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar exterior 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…
Black stains and rain streaks that have been left for many years may not come off even after cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jolly Pat finish and similar plastered surfaces.
If you try to forcibly remove black stains or rain streaks from Jolly Pat exterior 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 plastered exterior walls like Jolly Pat finish, 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 When the joints are severely deteriorated
If the joints of the siding exterior 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 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!
