1.Specialized Equipment for Exterior Renovations
At Kakeru Koumuten Co., Ltd., we have organized the following warehouses and material storage areas to provide more affordable and faster exterior renovations such as rain gutter repairs.
We have a total of 5 bases for material storage and showrooms.
In-house Scaffolding Materials


We own the scaffolding materials necessary for temporary scaffolding required for rain gutter repairs or replacements, allowing us to assemble scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs on scaffolding work.
In cases where temporary scaffolding is needed for partial rain gutter repairs or replacements, it typically takes a minimum of “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling,” resulting in at least 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 in-house, we can significantly reduce costs by shortening the construction period!
We have enough scaffolding materials for approximately 50 detached houses!
Storage of materials in our large in-house warehouse

We store roofing materials and components for rain gutters.
By ordering a large quantity of materials at once, we can procure 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 same person will handle everything, including sales and construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Various Permits Obtained & Skilled Workers Available


We have obtained construction industry permits and permits for industrial waste collection and transportation!
We have certified sheet metal workers and painting technicians on staff, and we are confident in our construction techniques.
We are also capable of handling large-scale rain gutter work for factories and other facilities!
4. Warranty and Aftercare

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.

Case Study of Rain Gutter Repair in Chiyoda-ku, Tokyo
Our Proposal
During the on-site inspection, we found that the rain gutter was generally deteriorated, so we proposed a rain gutter replacement work.
Common Issues Related to Rain Gutters

Rain Gutter is a system that plays the role of smoothly directing rainwater that falls on the roof to the ground.
You may not usually pay much attention to it, but if there is a problem with the rain gutter, 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.
Let me explain the main causes of troubles related to rain gutters.
1. Clogging from debris and fallen 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, obstructing drainage and causing blockages.
If you leave a blockage in the rain gutter unattended, it can lead to the sound of overflowing water becoming a nuisance or deformation of the rain gutter due to the weight of accumulated rainwater.
It is essential to regularly clean the rain gutters, or if you notice a blockage, prompt cleaning is necessary!
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 there is a high chance of immediate damage, so we recommend a complete replacement of the rain gutters!
3. Damage from Snow Accumulation or Strong Winds
Rain gutters can bend under the weight of snow or break due to strong winds. In particular 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
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 can be difficult to notice visually and may 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 Chiyoda-ku, Tokyo!
However, with so many contractors, you may find yourself struggling with “not knowing which one to choose..”.
For this reason, when requesting rain gutter replacement or repair, be sure 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 can choose a reliable contractor.
Check for 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 assess 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 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 making a request.
Confirm whether a warranty is provided
In case of any construction defects or issues after the work is completed, be sure to check if they provide a “construction warranty.”
Contractors who offer warranties are usually confident in their work, making them more trustworthy!
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 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 promptly 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, be sure to obtain estimates from multiple contractors.
Even for the same rain gutter replacement work, costs may vary between contractors, and warranties and after-sales services may differ as well.
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 essential.
When comparing estimates, be sure to check not only the costs but also
the details such as “types of rain gutters” and “spacing of support brackets”!
Check if the company performs rain gutter repairs and cleaning in-house
Finally, it’s important to confirm whether the work is done in-house.
If a sales company investigates and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there may be instances where customer requests are not fully communicated to the subcontractor, leading to potential issues.
By handling everything with one company, we can ensure prompt and cost-effective rain gutter work with accountability.
