What is wall cleaning…
Wall cleaning is one method of regular maintenance to keep the building’s appearance clean and to prolong the life of the exterior materials.
Are you facing these issues with dirty walls?
“I painted 5 years ago, and while it’s not time for a repaint, I’m concerned about one side being dirty…”
“Painting is expensive, so I’m not planning to do it yet, but I want to clean the exterior at a lower cost…”
“I have a three-story building, but can it be cleaned without scaffolding…?”
“Will this dirt come off with just washing…?”
“I’m worried that the detergent will discolor the exterior walls.”
If you have concerns like this, Kakeru Koumuten’s exterior wall cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior wall cleaning so popular in Nakagun, Kanagawa (Oiso Town and Ninomiya Town)?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior wall cleaning highly regarded in Nakagun, Kanagawa (Oiso Town and Ninomiya Town)!
Point 1 Overwhelmingly cost-effective
Typically, exterior wall painting and high-pressure washing require scaffolding, which inevitably incurs significant costs.
Kakeru Koumuten’s exterior wall cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior walls at about 1/10 the cost of exterior wall painting!
Point 2 Cleaning without damaging the exterior walls!
We use gentle water pressure instead of high pressure for cleaning. The brushes we use are specially designed to gently clean, removing dirt without damaging the exterior walls.
The detergents we use 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 onto them, so caution is necessary! Even if we cannot use a moss-resistant detergent, cleaning is still possible, so please rest assured!
Point 3 Exterior wall cleaning can be done with relatively little 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 will also have little to no odor.
The sound of the machinery used is relatively quiet as it is electric.
That said, if the building is close by, there may 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 The construction period is short!!
For regular residential exterior wall 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 Cleaning of areas other than the exterior walls 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 lot concrete)
・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 the site beforehand to confirm that the cleaning can be carried out without any issues on the day of the work.
Point 7 Estimates can also be provided using photos and drawings!
We can communicate via LINE or email, and we can 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 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 or rain streaks that have been left for many years may not come off even after cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jolly Pat finish.
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 special agents to clean gently as much as possible. 
As shown above, even when using special chemicals, some rain streaks may remain on Jolly Pat finish 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 If 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 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 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!

The cleaning method for plastered wall exteriors, such as Joripatto finish, differs from that of siding and other materials.

As shown in the above photo, we apply specialized cleaning agents for plastered walls using rollers and other tools.
By repeating the application of the cleaning agents and washing, we gradually remove the dark stains!
Due to the increased number of processes, the costs may be higher compared to other exterior walls, and there may be cases where stains cannot be completely removed.
