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 reduce the costs associated with scaffolding work.
In cases where temporary scaffolding is needed for partial rain gutter repairs or replacements, it typically takes at least three days of construction time 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 one day!
Since everything is done in-house, we can significantly reduce costs by shortening the construction period!
We have scaffolding materials for approximately 50 detached houses!
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, since we always have rain gutter components in stock, we can 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 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担当者 (representative) does not change, whether it be sales or construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!

We have obtained construction industry permits and permits for industrial waste collection and transportation!
We also have nationally certified sheet metal workers and painting technicians on staff, and we are confident in our construction techniques.
We are capable of handling large-scale rain gutter projects, such as those for factories!

We will respond as quickly as the same day!
6. Human Resource Development

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

Rain Gutter is a facility that smoothly directs rainwater falling from the roof to the ground.
You may not pay much attention to it on a daily basis, but if there are issues with the rain gutter, 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.
Let me explain the main causes of problems related to rain gutters.
1. Clogging 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 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 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 continuously 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 replacements may be difficult or likely to break quickly, 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 exposure and location, if the building is within 15 to 20 years old, it may be possible to extend the life of the rain gutters with partial replacements or repairs!
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 visually apparent 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 Bunkyo-ku, Tokyo!
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 can choose a reliable contractor.
Confirm whether 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 a contractor who is experienced and trustworthy!
You should 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 can also be 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, the reviews are generally trustworthy.
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 defects or issues after construction, confirm whether they provide a “construction warranty”!
Contractors who offer warranties are generally 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 for smooth communication since it will be shortly after the work is done!
Obtain estimates from multiple contractors for rain gutter replacement (at least three 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.
Even for the same rain gutter replacement work, costs may vary between contractors, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request 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 finer 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 conducts an investigation and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there may be instances where your requests are not fully communicated to the subcontractor, leading to potential issues.
By having everything handled by one company, we can ensure prompt and cost-effective rain gutter work with accountability.
