1.Facilities 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 set up scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs associated with scaffolding construction.
In cases where temporary scaffolding is needed 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 to cover 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 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 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 on waste disposal can be achieved.
Exterior Remodeling Dedicated Showroom


In the 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 ensured.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Obtaining Various Permits & Skilled Workers Available


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, such as those for factories!
4. Warranty and Aftercare
Rain gutter replacement work comes with a warranty!

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
In case of emergencies, such as rain gutters being dislodged due to a typhoon or being 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.

Our Proposal
Since the existing rain gutter was a discontinued product, we had to replace all of the rain gutters. However, because the damage was caused by wind, we suggested utilizing fire insurance.
The Panasonic/PC50 used in this project has a feature where it contains metal fittings inside, making it more durable and less prone to distortion 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.
Although you may not pay much attention to it on a daily basis, if there are issues with the rain gutter, it can cause rainwater to run down the exterior walls, leading to dirt and moss, and accelerate the deterioration of the building.
Additionally, water leaking from damaged areas can create noise as it hits the ground, potentially causing troubles or stress with neighbors.
Therefore, we will explain the main causes of problems 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 gutter, obstructing drainage and causing clogs.
If you leave the clogging of the rain gutter unattended, it can lead to the sound of overflowing water from the rain gutter becoming noise and deformation of the rain gutter due to the weight of accumulated rainwater.
It is necessary to regularly clean the rain gutters or to perform cleaning promptly if you notice any clogging!
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 the support brackets,” and “thermal deformation of the rain gutter”.
In cases of aging damage, partial replacement may be difficult or there is a high possibility of immediate damage, so we recommend complete replacement of the rain gutters!
3.Damage from Snow Accumulation and Strong Winds
The weight of snow can cause sagging, and strong winds can break the rain gutters. In particular 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 replacement or repair 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 noticeable at first glance and can 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 Aikou-gun, Kanagawa Prefecture (Aikawa Town and Kiyokawa Village)!
However, with so many contractors, you might struggle with “not knowing which one to hire..”.
Therefore, when requesting rain gutter replacement or rain gutter repair, let’s 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 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 delete low ratings, it is a trustworthy 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
Make sure to check if they provide a “workmanship warranty” in case any defects or issues arise after the installation!
Contractors who offer warranties are usually confident in their work, making them more trustworthy companies!
If rain gutter repairs or cleaning are performed, make sure to have before-and-after photos taken 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 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.
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 indispensable.
When comparing estimates, be sure to check not only the costs but also details such as “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Confirming if the company performs rain gutter repairs and cleaning in-house
Finally, let’s talk about whether we perform the work in-house.
When a sales company investigates and then requests a subcontractor, it can lead to extra time and costs.
Additionally, there are times when customer requests are not communicated 100% to the subcontractor, which can lead to troubles.
By handling everything in-house, we can provide responsible rain gutter work that is quick and cost-effective.
