1.Facilities Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has prepared 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 “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 performed by our own team, 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. Most contractors dispose of them all together, but by sorting and recycling the waste materials, significant cost reductions in 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 color 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. 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 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. 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 technicians, and we are confident in our construction techniques.
We are also capable of handling large-scale rain gutter installations for factories and other facilities!
4. Warranty and Aftercare
Rain gutter replacement work comes with a warranty!

5. Flexible and Prompt Response
In case of emergencies, such as if the rain gutter is about to come off due to a typhoon or if it is 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.

| Inquiry Details |
| We received an inquiry from a customer living in Tokyo, stating that “water leaks from the rain gutter when it rains.” The customer obtained estimates from four companies, including ours, and chose us because we offered the “lowest price” for the work! |
Our Proposal
Upon visiting the site, we found damage at the corners and joints of the rain gutter, which was causing water leakage. The existing rain gutter was a discontinued product, making partial replacements impossible, so we proposed a complete replacement of the rain gutter.
The Panasonic/PC50 used in this project has a metal frame inside, which makes it more durable and resistant to distortion compared to other rain gutters.
Common Issues Related to Rain Gutters

Rain Gutter is a system that smoothly directs rainwater falling from the roof to the ground.
While you may not think about it often, issues with the rain gutter can cause rainwater to run down the exterior walls, leading to dirt and moss accumulation, and accelerate the deterioration of the building.
Additionally, water leaking from damaged areas can create noise as it hits the ground, potentially causing disputes or stress with neighbors.
Therefore, let’s explain the main causes of troubles 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 that hinder 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 conduct cleaning 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 replacements may be difficult or prone to quick damage, so we recommend a complete replacement of the rain gutters!
3.Damage from Snow Accumulation and Strong Winds
Rain gutters can bend under the weight of snow or crack due to strong winds. In some regions, the impact of falling snow can 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 replacements or repairs 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 obvious at first glance 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 Nishitama-gun, Tokyo!
However, with so many contractors, you might find yourself struggling 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.
● Ensure they 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 they perform rain gutter repairs in-house
By confirming the above four points, you can 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 a contractor who is experienced and trustworthy!
You should refer to the contractor’s website for their work history and customer reviews to make a judgment.
It may also be effective to check their achievements on social media platforms like Instagram!
It is also effective to look at reviews of roofing repair contractors on Google and review sites for reference!
A recommended review site is “Google”.
Since it is difficult to delete 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 requesting their services.
Confirm whether a warranty is provided
In case of any defects or issues after construction, make sure to check if they provide a “construction warranty”!
Contractors who offer a warranty tend to have confidence in their work, making them more trustworthy companies!
If rain gutter repairs or cleaning are performed, ask them to take before-and-after photos of areas that are not visible from below for confirmation!
For rain gutter cleaning, ensure they 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 three companies)
Since the installation of temporary scaffolding is necessary for rain gutter replacement, 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 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 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”!
Confirm whether the company performs rain gutter repairs and cleaning in-house
Finally, it’s important to know if the work is done by the company itself.
If a sales company investigates 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, which can lead to troubles.
By having everything handled by one company, we can provide prompt and cost-effective responsible rain gutter work.
