What is exterior wall cleaning…
Exterior wall cleaning is a 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 structure.
When the exterior wall becomes dark or moss grows, the common options were “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 becomes 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 in need of painting, 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 is it possible to clean without scaffolding…?”
“Will this dirt come off just with 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 so popular in Fussa City?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Fussa City!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs significant costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior at about one-tenth 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 specialized brushes that 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 on them, so caution is necessary! However, even if we cannot use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Can clean exterior walls with relatively less inconvenience to neighbors!
By using a special brush with a gentle water flow, it is less likely to scatter than spraying water directly with a hose!
The detergent used also has very little odor.
The machine used is electric and 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 there are cars nearby, we will cover them with car seat protection!
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 Cleaning other areas is also possible!
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.)
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 confirm whether the work can proceed smoothly on the day of cleaning before the construction.
Point 7 Estimates can be provided using photos and drawings!
We can provide estimates through LINE or email by using photos and drawings (floor plans and elevation drawings) of the building!
In cases where it is difficult to provide estimates based on photos or drawings, we will visit the site for an on-site survey.
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” when it comes to 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 be removed even with cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from textured wall finishes like Jolly Pat.
If you try to forcibly remove black stains 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 textured wall finishes like Jolly Pat, 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 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 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!
