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 photo above, 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.
When the exterior wall becomes dark 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 it yourself 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 issues with dirty exterior walls?

For those with such concerns, Kakeru Koumuten’s exterior cleaning can solve your problems!

Why is Kakeru Koumuten’s exterior cleaning so popular in Hachioji City?

We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning highly praised in Hachioji City!

Point 1 Overwhelmingly low cost

Typically, exterior painting and high-pressure washing of the exterior walls require scaffolding, which inevitably incurs significant costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior walls at about one-tenth the cost of exterior painting!

Point 2 Cleaning without damaging the exterior!

We use gentle water pressure instead of high pressure for washing. The brushes used are specialized and 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, so caution is necessary! 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 inconvenience to neighbors!

By using a special brush with a gentle water flow, it is less likely to splash compared to using a hose directly!
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 always make sure to greet the neighbors before starting the work.
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 primarily done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed photos of the work and send them to you later.

Point 5　Can clean areas other than the exterior as well!

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 (some restrictions may apply.)

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 greet the neighbors.
We will also confirm that everything is in order for the cleaning on the day of the work.

Point 7　Estimates can be provided using photos and drawings!

We can provide estimates based on photos and drawings (floor plans and elevation drawings) through LINE or email!
In cases where it is difficult to estimate from 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 cleanable.
This is to prevent leaks and peeling of the paint film.

Caution 2 Some stains may not come off…

Long-standing black stains or rain streaks may not be removed even after 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 walls, it may lead to 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 rain streaks may remain on Jollypat finished 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 are severely deteriorated, it may lead to leaks, and therefore, 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 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 exterior walls with plaster will be cleaned using a special cleaning method!
