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 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 it yourself with a brush or sponge using a household cleaning machine, but it would be quite difficult for the second or third floors.
Do you have any concerns about dirt on your exterior walls?
“It’s been 5 years since I painted, and while it’s not time for a repaint, 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 at a lower cost…”
“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 will discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior cleaning can solve them!
Why is Kakeru Koumuten’s exterior cleaning popular in Kawasaki City, Kawasaki Ward?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning well-received in Kawasaki City, Kawasaki Ward!
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 specialized and clean gently, removing dirt without damaging the exterior.
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! Even if a moss-resistant detergent cannot be used, cleaning is still possible, so rest assured!
Point 3 Can clean exterior walls with minimal inconvenience to neighbors!
By using a special brush with a gentle water flow, it is less likely to scatter than using a hose directly!
The detergent used also has very little 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 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 at home!
Of course, we will take detailed construction photos and send them to you later.
Point 5 Can clean not only the exterior walls but also other areas!
In addition to the exterior walls, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (such as parking lots)
・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 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 provide estimates based on photos and drawings (floor plans and elevation drawings) exchanged via 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 of” during 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…
Black stains and rain streaks that have been left for many years may not come off even after cleaning.
In particular, removing rain streaks and black stains from textured wall finishes like Jolly Pat is difficult.
If you try to forcibly remove black stains 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, 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 walls every 3 to 5 years without leaving dirt!
Caution 3 Severe deterioration of joints
If the joints of the siding exterior walls are severely deteriorated, it may lead to leaks, and therefore, we may not be able to 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 perform 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!
