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 darkens or moss grows, the common options are “exterior 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 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 issues with dirty exterior walls?
“I painted 5 years ago, and while it’s not in bad shape, I’m concerned about one area that’s dirty…”
“Painting is expensive, so I don’t plan to do it yet, but I’d like 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 might discolor the exterior…”
If you have concerns like these, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning popular in Totsuka-ku, Yokohama?
Here are the “7 points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Totsuka-ku, Yokohama!
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 1/10 the cost of exterior painting!
Point 2 Cleaning without damaging the exterior!
We clean using gentle water pressure instead of high pressure. The brushes used are specially designed to clean gently, removing dirt without damaging the exterior.
The detergents used are formulated to prevent discoloration of the sashes and exterior walls!
We also vary the detergents used depending on the type of dirt, such as rain stains, blackening, and moss!
※Caution is necessary with detergents that are strong against moss, as they can harm or kill plants if they splash onto them! However, even if a moss-resistant 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 compared to using a hose directly!
The detergent used also has very little odor.
The sound of the machinery used is relatively quiet as it is electric.
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 a typical house 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 construction and send them to you later.
Point 5 Cleaning of areas other than the exterior is also possible!
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.)
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 check before the cleaning day to ensure that the work can proceed without any issues.
Point 7 Estimates can be provided using photos or drawings!
We can communicate via LINE or email, and provide estimates based on photos and drawings (floor plans and elevation drawings)!
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 cautious about during exterior wall cleaning?
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 textured wall finishes like Jolly Pat.
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 required.
Depending on sunlight and location, it is recommended to clean the walls every 3 to 5 years without leaving dirt!
Caution 3 If the joints are severely deteriorated
If the joints of the siding exterior walls 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 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!
