What is exterior wall cleaning…
Exterior wall cleaning is a 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 if the paint film on the exterior wall is in good condition, rain streaks, darkening, and moss can occur due to sunlight and structure.
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 is within reach, such as around the first floor, it may be possible to clean with a DIY 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?
“I painted 5 years ago, and while it’s not time for a repaint, 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 might discolor the exterior walls.”
If you have concerns like these, Kakeru Koumuten’s exterior wall cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior wall cleaning popular in Sumida-ku?
Here are the “7 Points” that make Kakeru Koumuten’s exterior wall cleaning well-received in Sumida-ku!
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 for about one-tenth 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 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!
※Caution is necessary with detergents that are strong against moss, as they can kill or affect plants and greenery if they splash. However, even if we can’t use a moss-resistant detergent, cleaning is still possible, so please 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 very little odor.
The machine used is electric and relatively quiet.
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 single-family home exterior cleaning, it often can be completed in just one day, even for full cleaning!
Since the work is primarily 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 can be done for areas other than the exterior!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (like parking lots)
・Carports
・Roofs and solar panels (some restrictions may apply.)
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 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 or 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 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 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 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 specialized agents to clean gently as much as possible. 
As shown above, even when using specialized chemicals on Jolly Pat finish walls, some rain streaks may remain, 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 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 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 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!
