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.
Are you facing these concerns about dirty walls?
“I painted 5 years ago and it’s not time for repainting, but I’m worried 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 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 Saitama Prefecture?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior wall cleaning highly regarded in Saitama Prefecture!
Point 1 Overwhelmingly cost-effective
Typically, exterior wall painting and high-pressure washing require scaffolding, which inevitably incurs high 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 clean gently, removing dirt without damaging the exterior walls.
The detergents we use are formulated to prevent discoloration of the frames 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 can’t use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Exterior wall cleaning with minimal disturbance to neighbors!
Since we apply gentle water flow from a specialized brush, it is less likely to splash compared to directly spraying water with a hose!
The detergents we use also produce little to no odor.
The machinery we use operates relatively quietly as it is electric.
That said, if the buildings are close together, we may cause some inconvenience, so we always make sure to greet the neighbors before starting the work.
If there are cars nearby, we will protect them with car seat covers!
Point 4 Short construction period!!
For regular single-family home exterior wall cleaning, it is often completed in just one day even with full cleaning!
Since the work is generally done outdoors, cleaning can be done even if you are not at home!
Of course, we will take detailed photos of the work, and we will send the photos 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 any 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 we will greet the neighbors.
We will visit the site before the cleaning day to confirm 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 or drawings (floor plans and elevation drawings) of the building!
There may be cases where it is difficult to provide an estimate using photos or drawings, in which case we will conduct a site survey.
Estimates will be sent within 1 to 2 business days after receiving the photos or drawings!
What should you be careful about when cleaning exterior walls?
Next, we will explain the “5 points to be cautious about” during exterior wall cleaning!
Note 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar exterior walls with many cracks may become impossible to clean.
This is to prevent leaks and peeling of the paint film.
Note 2 Some stains won’t come off…
Black stains and rain streaks that have been left unattended for many years may not come off even with cleaning.
In particular, it is difficult to completely remove rain streaks and black stains from exterior walls with Jollypat finishes.
If you try to forcibly remove black stains or rain streaks from Jollypat exterior walls, it may cause discoloration or damage, so we will use specialized agents to clean as gently as possible. 
As mentioned above, even when using specialized chemicals, some rain streaks may remain on Jollypat finishes and other plastered exterior walls, so caution is necessary.
Depending on sunlight and location, it is recommended to clean every 3 to 5 years without leaving dirt unattended!
Note 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 Work may not be possible depending on the structure of the building.
It may be difficult to perform work in areas such as above eaves, above bay windows, or extremely narrow spots.
We will check during the investigation.
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 generators or tanks!

We perform cleaning of plastered exterior walls using a special cleaning method!
Cleaning methods for plastered exterior walls with a Jolly Pat finish differ from those for siding and other materials.

As shown in the photos above, we apply specialized chemicals for plastered walls using rollers for cleaning.
We gradually remove the dark stains by repeating the application of chemicals and washing!
Due to the increased number of processes, the cost may be higher compared to other exterior walls, and there may be cases where dirt cannot be completely removed.
