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 above photo, even when the paint film on the exterior wall is in good condition, rain streaks, darkening, and moss can occur due to sunlight and structure.
Typically, when the exterior wall darkens or moss grows, 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?
“It’s been 5 years since I painted, and while it’s not time for a repaint, I’m concerned about one area 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 with just washing…?”
“I’m worried that the detergent will discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior wall cleaning can solve them!
Why is Kakeru Koumuten’s exterior wall cleaning popular in Sakae-ku, Yokohama?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior wall cleaning well-received in Sakae-ku, Yokohama!
Point 1 Overwhelmingly low cost
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 washing. The brushes used are specially designed to clean gently, removing dirt without damaging the exterior walls.
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 onto them! However, even if we can’t use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Can clean the exterior without causing much trouble to the neighbors!
By using a special brush with 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 by, 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 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 home!
Of course, we will take detailed photos of the work, and we will send the photos to you later.
Point 5 Cleaning can be done for areas other than the exterior!
In addition to the exterior walls, cleaning can also be done for 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)
If there are 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 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 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 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 suitable for cleaning.
This is to prevent leaks and peeling of the paint film.
Caution 2 Some stains may not come off…
Stains such as blackening or 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 blackening from exterior walls with Jollypat finishes.
If you try to forcibly remove blackening or rain streaks from Jollypat 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, some streaks from rain may remain on Jollypat finishes and similar plastered 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 When the joints are severely deteriorated
If the joints of the siding exterior are severely deteriorated, it may lead to leaks, and in such cases, we may not be able to carry out 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 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!

・We will wash off moss, black stains, and rain streaks from the exterior walls with a special brush!
The exterior walls with plaster will be cleaned using a special washing method!
The cleaning method for plastered wall exteriors, such as Jolly Pat finish, differs from that of siding and other materials.

As shown in the above photos, we apply specialized cleaning agents for plastered walls using rollers and other tools.
By repeatedly applying 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.

| Concrete for Parking Lots and Other Areas | 500 yen–550 yen/㎡ |
