In this article, we will introduce the case studies, benefits, precautions, and costs of exterior wall cleaning in Nakahara-ku, Kawasaki!
Estimates and consultations are free!
We welcome comparative estimates!
What is exterior wall cleaning…
Exterior wall cleaning is a method of regular maintenance to keep the building’s beautiful appearance and prolong the life of the exterior materials.
As shown in the above photo, 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.
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 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 concerns with exterior wall dirt?
“It’s been 5 years since I painted, and while it’s not time for a new coat, I’m concerned about one area that’s 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 these, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning popular in Nakahara-ku, Kawasaki?
We would like to introduce the “7 points” that make Kakeru Koumuten’s exterior cleaning well-received in Nakahara-ku, Kawasaki!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs high 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 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.
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! However, even if we cannot use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Can clean the exterior without causing much inconvenience to neighbors!
By using a special brush to apply a gentle water flow, it is less likely to scatter than using a hose directly!
The detergent used also has little to no odor.
The machine noise is relatively quiet as it is electric.
That said, if the building is close, there may still be some inconvenience, so we always make sure to 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 construction photos 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)
・Concrete surfaces (such as parking lots)
・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 confirm that the work can be carried out without issues on the day of cleaning.
Point 7 Estimates can be provided using photos and drawings!
We can provide estimates based on photos and drawings (floor plans and elevation plans) exchanged via LINE or email!
However, if it is difficult to estimate 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” 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 won’t come off…
Stains from years of neglect, such as darkening and rain streaks, may not be removable even with cleaning.
In particular, rain streaks and darkening on plastered walls like Jolly Pat finish are difficult to completely remove.
If you try to forcibly remove darkening 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 on plastered walls like Jolly Pat finish, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean every 3 to 5 years without leaving dirt!
Caution 3 Severe deterioration of joints
If the joints of the siding exterior are severely deteriorated, it may lead to leaks, and there may be cases where we cannot 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!
