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.
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 it yourself using a brush or sponge with 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’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 Nishitokyo City?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Nishitokyo 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 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! However, even if we can’t use a moss-resistant detergent, 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 greet the neighbors before starting the work.
If cars are 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 basically 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 areas other than the exterior as well!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete floors (such as parking lots)
・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 to confirm that the work can be carried out without issues on the cleaning day.
Point 7 Estimates can be provided using photos and 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 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 long-term neglect, such as blackening or rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and blackening from exterior walls with Jolly Pat finish.
If you try to forcibly remove blackening or rain streaks from Jolly Pat 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 on exterior walls with Jolly Pat finish, some rain streaks may remain, 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 Severe deterioration of joints
If the joints of the siding exterior wall are severely deteriorated, it may lead to leaks, and in such cases, we may not be able to perform the work.
Note 4 There may be cases where construction is not possible due to the building’s structure.
It may be difficult to perform 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 the cleaning process, 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!

The exterior walls of plastered walls will be cleaned using a special cleaning method!
The cleaning method for plastered exterior walls with Jolly Pat finish differs from that of siding and other materials.

As shown in the above photo, we apply a special cleaning agent for plastered walls using a roller or similar tool.
By repeating the application of the cleaning agent and washing, we gradually remove the dark stains!
Due to the increased number of processes, the cost may be higher compared to other exterior walls, and there may be cases where stains cannot be completely removed.

| Concrete for Parking Lots and Other Areas | 500 yen–550 yen/㎡ |
