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, dark spots, and moss can occur due to sunlight and structure.
Typically, when the exterior wall becomes dark 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 concerns with dirty exterior walls?
“I painted 5 years ago, and while it’s not in need of painting, 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 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 Tachikawa City?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Tachikawa City!
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 washing. 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 splash on 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 with a gentle water flow, it is less likely to splash than using a hose directly!
The detergent used also has almost no odor.
The machine used is electric and relatively quiet.
That said, if the building is close, there may still be some inconvenience, so we will always 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 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 at home!
Of course, we will take detailed photos during the work and send them 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)
・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 the work!
Before the work, we will check the condition of the exterior walls and joints and greet the neighbors.
We will confirm before the cleaning day whether the work can be carried out without any issues.
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)!
There may be cases where it is difficult to provide an estimate based on photos or drawings, in which case we will visit the site for an inspection.
We will send the estimate 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…
Black stains and rain streaks that have been left for many years may not come off even with cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jollypat finish.
If you try to forcibly remove black stains or rain streaks from Jollypat exterior 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 Jollypat finish and other plastered exterior walls, 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 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 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!
