“Improves the aesthetics of the building at a lower cost compared to exterior wall painting”
That said, exterior wall cleaning is still a relatively unknown service.
In this article, we will introduce the case studies, benefits, precautions, and costs of exterior wall cleaning in Adachi-ku!
Estimates and consultations are free!
We welcome comparative estimates!
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 structural factors.
Typically, when the exterior wall becomes dark or mossy, 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 using a brush or sponge with a household cleaning machine, but it becomes quite difficult for the second or third floors.
Do you have these concerns about exterior wall stains?
“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 with just cleaning…?”
“I’m worried that the detergent will 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 so popular in Adachi-ku?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior cleaning highly praised in Adachi-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 gently clean 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 on them, so caution is necessary! 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 little to 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 cars are 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 generally done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed photos during the work and send them to you later.
Point 5 Cleaning can also be done for areas other than the exterior!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (like parking lots)
・Carports
・Roofs and solar panels (some restrictions may apply)
Please feel free to consult us about any other areas of concern!
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 and drawings!
We can provide estimates based on photos and drawings (floor plans and elevation drawings) through LINE or email!
In some cases, it may be difficult to provide an estimate based on photos or drawings, and if that happens, 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 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 darkening or rain streaks, may not be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from painted walls like Jolly Pat finish.
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 when using specialized chemicals on painted walls like Jolly Pat finish, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean 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!
