The reasons why our company is entrusted with rain gutter repairs by customers in Aoba-ku, Kawasaki include
“Having a base in Yokohama” as one of the reasons,
“Our unique strengths in rain gutter repairs that cannot be imitated by other companies”
which have received high praise from many customers.

1.Facilities Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has organized the following warehouses and material storage areas to provide more affordable and faster exterior renovations such as rain gutter repairs.
We have established five bases centered around Aoba-ku, Yokohama for material storage and showrooms.
In-House Scaffolding Materials


We own the scaffolding materials necessary for temporary scaffolding required for rain gutter repairs and replacements, allowing us to assemble scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also reduce the costs associated with scaffolding construction.
In cases where temporary scaffolding is required for partial rain gutter repairs or replacements, it typically takes at least “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling,” resulting in a minimum of three days of construction time.
The longer the construction period, the more “labor costs” and “transportation costs” will accumulate.
In our case, we can complete “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling” in as little as one day!
Since all work is performed by our own staff, we can significantly reduce costs by shortening the construction period!
We have enough scaffolding materials to cover approximately 50 single-family homes!
Storage of materials in our large in-house warehouse

We store roofing materials and rain gutter components.
By ordering a large quantity of materials at once, we can purchase materials at a lower cost!
Additionally, we always have rain gutter components in stock, allowing us to respond quickly to emergency rain gutter repairs!
In-house sorting of waste materials
In rain gutter repairs, various waste materials such as PVC and metal are generated.
Most contractors dispose of them all together, but by sorting and recycling the waste materials, significant cost savings on waste disposal can be achieved.
Exterior Renovation Dedicated Showroom


In our showroom, not only can you have meetings, but you can also
directly check the actual structure and colors of the rain gutters.
2.Complete In-House Construction
One of Kakeru Koumuten’s major strengths is complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd., allowing us to keep costs down while providing high-quality rain gutter work.
Additionally, one representative will assist you from the estimate to the completion of the work.
Since the担当者 does not change, such as sales and construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Acquisition of various permits and presence of skilled workers


We have obtained construction industry permits and permits for industrial waste collection and transportation!
We have certified sheet metal workers and painting specialists on staff, and we are confident in our construction techniques.
We are also capable of handling large-scale rain gutter projects for factories and other facilities!
4. Warranty and Aftercare
Rain gutter replacement work comes with a warranty!
If you have questions about the warranty, please click the image above!
In the unlikely event that water leakage is not resolved after rain gutter cleaning or repair, we will take responsibility and respond accordingly!
5. Flexible and Prompt Response
In case of emergencies, such as rain gutters being dislodged due to a typhoon or at risk of falling due to snow damage, we can provide temporary measures to ensure safety.
We will respond as quickly as the same day!
6. Human Resource Development
To enhance skills, we create various building models and conduct practical training.
Since rain gutter repairs and replacements require various modifications depending on the site, we regularly provide technical training to ensure that each staff member can respond effectively.

Our Proposal
Since there were issues with rain leaking from the roof and the distortion of the rain gutter, which hindered proper drainage, we proposed a rain gutter replacement project.
Common Problems Related to Rain Gutters

Rain Gutters are facilities that smoothly channel rainwater from the roof to the ground.
You may not pay much attention to them on a daily basis, but if there are issues with the rain gutters, rainwater can cause dirt and moss to accumulate on the exterior walls, accelerating the deterioration of the building.
Additionally, water leaking from damaged areas can create noise as it hits the ground, leading to troubles and stress with neighbors.
Here are the main causes of problems related to rain gutters.
1. Clogs from debris and leaves
Many issues with rain gutters stem from blockages.
Leaves, dust, and small branches that fall onto the roof can flow into the rain gutters, causing blockages by hindering drainage.
If you leave a blockage in the rain gutter unattended, it can lead to the sound of overflowing water becoming noise or warping of the rain gutter due to the weight of accumulated rainwater.
It is essential to regularly clean the rain gutters or to clean them promptly if you notice a blockage!
2. Aging and UV Damage
Since rain gutters are constantly exposed to the elements, they are continually affected by UV rays and rain and wind.
This can lead to “cracks in the rain gutter,” “rust on support brackets,” and “thermal deformation of the rain gutter”.
If aging is the cause, partial replacement may be difficult or may lead to quick damage, so we recommend a complete replacement of the rain gutters!
3. Damage from Snow Accumulation and Strong Winds
Rain gutters can sag under the weight of snow or break due to strong winds. In some regions, the impact of falling snow can also deform or damage the rain gutters.
Depending on sunlight and location, if the building is within 15 to 20 years old, it may be possible to manage with partial replacement or repair of the rain gutters!
4. Improper Installation
If the slope was not correctly set during new construction or renovation, or if the spacing of the brackets was inappropriate, it can lead to drainage issues or sagging. This may not be easily noticeable and can go unnoticed for a long time.
If you are still within the warranty period, be sure to request adjustments or repairs promptly!
How to Choose a Rain Gutter Repair Contractor
There are many rain gutter repair contractors available in Kawasaki City, Kawasaki Ward!
However, with so many contractors, you might struggle with “not knowing which one to choose..”.
For this reason, when requesting rain gutter replacement or repair, it is important to check the following four points.
● Have extensive experience in rain gutter repair and replacement
● Confirm whether a warranty is provided
● Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
● Check if the company performs rain gutter repairs in-house
By confirming the above four points, you will be able to choose a reliable contractor.
Check if they have extensive experience in rain gutter repair
About 10-20% of rain gutter issues are caused by poor workmanship during installation.
To prevent problems, it is crucial to hire an experienced and trustworthy contractor!
You need to refer to the company’s website for their track record and customer reviews to make a judgment.
Checking their achievements on social media platforms like Instagram can also be effective!
It is also effective to look at roof repair contractors based on reviews from Google and review sites!
A recommended review site is “Google”.
Since it is difficult to remove low ratings, it is a reliable source of reviews.
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Confirm whether a warranty is provided
To prepare for any potential issues or defects after construction, confirm whether they provide a “construction warranty”!
Contractors who offer warranties are usually confident in their work, making them more trustworthy!
If rain gutter repairs or cleaning are performed, make sure to take before-and-after photos of areas that are not visible from below!
For rain gutter cleaning, request a water flow test to ensure that rainwater does not overflow.
After rain gutter cleaning or repair, check for any leaks during rainy weather, and if there are any issues, contact the contractor immediately as it will facilitate smooth communication shortly after the work is done!
Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
Since rain gutter replacement requires the installation of temporary scaffolding, the costs can be high.
Therefore, when requesting rain gutter replacement, it is essential to obtain estimates from multiple contractors.
Even for the same rain gutter replacement work, costs can vary between contractors, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request services from your preferred repair contractor at a lower price, obtaining estimates from multiple contractors is indispensable.
When comparing estimates, be sure to check not only the costs but also the details such as
“the type of rain gutter” and “the spacing of support brackets” for a thorough comparison!
Check if rain gutter repairs and cleaning are performed in-house
Finally, this concerns whether the work is done in-house.
If a sales company investigates and then requests a subcontractor, it will take more time and incur additional costs.
Moreover, there are instances where customer requests are not fully communicated to the subcontractor, leading to potential troubles.
By handling everything with one company, we can ensure prompt and cost-effective rain gutter work with accountability.
