1.Specialized Equipment for 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 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 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 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 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 licenses and permits for 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

In the unlikely event that water leakage is not improved after rain gutter cleaning or repair, we will take responsibility and respond accordingly!
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.

| Inquiry Details |
| We received an inquiry from a customer living in Tokyo who said, “Water leaks from the rain gutter when it rains.” The customer obtained estimates from four companies, including ours, and chose us because we were “the cheapest” 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 features internal brackets, making it more durable and less prone to warping compared to other rain gutters.
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 think about it often, but if there are issues 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.
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 by hindering drainage.
If you leave a blockage in the rain gutters unattended, it can lead to the sound of overflowing water becoming noise or deformation of the rain gutters 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 outside air, they are continuously affected by UV rays and rain and wind. This can lead to “cracks in the rain gutters,” “rust on the support brackets,” and “thermal deformation of the rain gutters”.
If aging is the cause, partial replacements may be difficult or prone to quick damage, so we strongly recommend full 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 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 replacements or repairs of the rain gutters!
4.Improper Installation at the Time of Setup
If the slope was not properly 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 Mitaka City, 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 conducts its own rain gutter repairs
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 construction defects during installation.
To prevent problems, it is essential to hire an experienced and trustworthy contractor!
You should refer to the company’s website for their construction achievements and 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 reviews on Google and review sites to find roof repair contractors!
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
To prepare for any construction defects or issues that may arise after the work is completed, confirm whether they offer a “construction warranty”!
Contractors who provide a warranty are usually confident 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 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 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, make 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 check 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 customer requests are not fully communicated to the subcontractor, which can lead to troubles.
By having everything handled by one company, we can ensure prompt and cost-effective responsible rain gutter work.
