1.Equipment 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 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 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 canprocure materials at a lower cost!
Additionally, we always have rain gutter components in stock, allowing us torespond 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 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. Various Permits Obtained & Skilled Workers Available


We have obtained construction industry permits and industrial waste collection and transportation permits!
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 Minami-ku, Yokohama, Kanagawa Prefecture
Rain Gutter Replacement Work (Only for Damaged Eaves Gutter)
Our Proposal
Since only the eaves gutter was damaged and the vertical gutter was intact, we proposed to replace only the damaged eaves gutter!

Common Troubles Related to Rain Gutters

Rain Gutters are facilities that play a role in smoothly directing rainwater that falls on 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.
Here are 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 clogs.
If you leave rain gutter blockages unattended, the sound of overflowing water from the rain gutter can become a nuisance, and the weight of accumulated rainwater can cause distortions in the rain gutter.
It is essential to regularly clean the rain gutters or to perform cleaning promptly if you notice any blockages!
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”.
In cases of aging damage, partial replacements may be difficult or prone to quick failure, 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 certain areas, the impact of falling snow can deform or damage the rain gutters.
Depending on sunlight exposure and location, if the building is 15 to 20 years old, it may be possible to manage with partial rain gutter replacements or repairs!
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 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 Minami-ku, Yokohama!
However, with so many options, you might find yourself struggling with “not knowing which one to choose..”.
Therefore, when requesting rain gutter replacements or repairs, be sure to 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.
Confirming 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 important to hire an experienced and trustworthy contractor!
You should assess their work history and reviews on their company website.
Checking their achievements on social media platforms like Instagram can also be effective!
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 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.
Confirming the presence or absence of a warranty
To prepare for any potential issues or defects 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 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, as it will facilitate smooth communication shortly after the work is done!
Obtaining estimates from multiple contractors for rain gutter replacement (at least 3 companies)
Since rain gutter replacement requires the installation of temporary scaffolding, 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, warranties, and after-sales services may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request the 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 like “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Confirming whether the company performs rain gutter repairs and cleaning in-house
Finally, let’s discuss whether we conduct our own construction work.
When a sales company investigates and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there are instances where customer requests are not fully communicated to the subcontractor, which can result in troubles.
By handling everything in-house, we can ensure prompt and cost-effective rain gutter work with accountability.
