which has 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 5 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 needed for partial rain gutter repairs or replacements, it typically takes at least “3 days of construction period” for “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling.” 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 1 day!
Since all work is done in-house, we can significantly reduce costs by shortening the construction period!
We have enough scaffolding materials for 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 waste separation
In rain gutter repairs, various waste materials such as PVC and metal are generated. While most contractors dispose of them all together, by sorting and recycling the waste materials, significant cost reductions 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 its complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd. in a consistent manner, 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 person in charge does not change, whether it’s the sales representative or the construction management representative, 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 permits for construction work and industrial waste collection and transportation!
We also have nationally certified sheet metal workers and painting specialists on staff, and we are confident in our construction techniques.
We are 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!

5. Flexible and Prompt Response

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.

Common Issues Related to Rain Gutters

Rain Gutters are facilities that smoothly direct rainwater falling from the roof to the ground.
You may not usually pay much attention to them, but if there are issues with the rain gutters, rainwater can run down the exterior walls, causing dirt and moss, and 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.
Therefore, let me explain the main causes of troubles related to rain gutters.
1. Clogs from Debris and Leaves
Many issues with rain gutters stem from clogs. Leaves, dust, and small branches that fall on the roof can flow into the rain gutters, obstructing drainage and causing blockages.
If you leave rain gutter clogs unattended, the sound of overflowing water from the rain gutter can become noise, and the weight of rainwater accumulated in the rain gutter can cause deformation.
It is necessary to regularly clean the rain gutters or to perform cleaning promptly if you notice a clog!
2.Aging and UV Damage
Since rain gutters are constantly exposed to the outside air, they continue to be 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 the cause is aging, partial replacement may be difficult or there is a high possibility of immediate damage, so we recommend complete replacement of the rain gutters!
3.Damage from Snow Accumulation and Strong Winds
The weight of snow can cause sagging, and strong winds can break the rain gutters. In certain regions, the impact of falling snow can deform or damage the rain gutters.
Depending on sunlight exposure 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 at the Time of Setup
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 it is 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 Hadano City, Kanagawa Prefecture!
However, with so many contractors, you might struggle with “not knowing which one to choose..”.
Therefore, when requesting rain gutter replacement or repair, let’s check the following four points.
●Having extensive experience in rain gutter repair and replacement
●Confirming the presence or absence of a warranty
●Obtaining estimates from multiple contractors for rain gutter replacement (at least 3 companies)
●Checking if the company performs rain gutter repairs in-house
By confirming the above 4 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 important to hire a contractor who is experienced and trustworthy!
You need to judge based on the company’s website showcasing their work and customer reviews.
Checking their achievements on social media platforms like Instagram can also be effective!
It is also effective to look at roof repair contractors by referring to reviews on 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 making a request.
Confirm the presence or absence of a warranty
To prepare for any potential defects or issues after construction, confirm whether they provide a “construction warranty”!
Contractors that offer warranties tend to have confidence in their work, making them more trustworthy companies!
If rain gutter repair or cleaning is performed, make sure to take before-and-after photos of areas that are not visible from below!
For rain gutter cleaning, have them perform a water flow test to check if rainwater overflows.
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 3 companies)
Since the installation of temporary scaffolding is necessary for rain gutter replacement, the costs can be high. Therefore, when requesting rain gutter replacement, it is essential to obtain estimates from multiple contractors.
The costs for the same rain gutter replacement can vary between contractors, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired 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 details such as “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Check if they perform rain gutter repairs and cleaning in-house
Finally, let’s discuss whether we perform the work ourselves.
When a sales company investigates and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there are cases where customer requests are not communicated 100% to the subcontractor, which can lead to troubles.
By handling everything in-house, we can provide responsible rain gutter work that is both quick and cost-effective.
Kakeru Koumuten Co., Ltd. conducts everything from existing rain gutter inspections to actual repairs in-house!
