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 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 to providequick responses for 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 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!

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

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.

Common Issues Related to Rain Gutters

Rain Gutters are facilities that serve the purpose of smoothly directing rainwater from the roof to the ground.
You may not think about them often, 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.
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 clogs.
Leaves, dust, and small branches that fall on the roof can flow into the rain gutters, obstructing drainage and causing clogs.
If clogs in the rain gutters are left unattended, the sound of overflowing water can become a nuisance, and the weight of accumulated rainwater can cause warping in the rain gutters.
It is essential to regularly clean the rain gutters or to clean them promptly if you notice any clogs!
2. Aging and Deterioration from UV Rays
Rain gutters are constantly exposed to the outside air, which means they are continually 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”.
If deterioration is due to aging, partial replacement may be difficult or there is a high possibility of immediate damage, so we strongly 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 crack the rain gutters. In particular regions, the impact of falling snow can deform or break 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 replacement or repair of the rain gutters!
4. Improper installation during construction
If the slope was not correctly set during new construction or remodeling, or if the spacing of the brackets was inappropriate, it can lead to drainage issues or sagging. This may not be noticeable at first 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 Saiwai-ku, Kawasaki!
However, with so many contractors, you might struggle with “not knowing who to hire…” when it comes to choosing a contractor.
Therefore, when requesting rain gutter replacement or repair, be sure to check the following four points:
● Have extensive experience in rain gutter repair or replacement
● Confirm whether a warranty is available
● Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
● Confirm whether they conduct rain gutter repairs in-house
By checking these 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 troubles are caused by poor workmanship during installation.
To prevent issues, it is important to hire a reliable contractor with ample experience!
You should evaluate 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 can be beneficial to look at roof repair contractors using reviews from Google and review sites as references!
A recommended review site is “Google”.
Since it is difficult to remove low ratings, it serves as a trustworthy source of reviews.
If there are many negative reviews or no reviews at all, it might be wise to refrain from hiring that contractor.
Confirm Whether a Warranty is Provided
In case of any workmanship issues or defects after installation, make sure to confirm if they provide a “workmanship warranty”!
Contractors who 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, have them perform a water flow test to ensure that rainwater does not overflow.
After cleaning or repairing the rain gutters, 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 3 companies)
Since replacing rain gutters 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 and warranties or after-service may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To hire your preferred repair contractor at a lower cost, obtaining estimates from several companies is indispensable.
When comparing estimates, be sure to check not only the costs but also the details such as
“the type of rain gutter” and “the spacing of support brackets” for accurate comparison!
Confirm Whether They Perform Rain Gutter Repairs and Cleaning In-House
Finally, it is important to confirm whether they perform the work in-house.
If a sales company investigates and then hires subcontractors, it can lead to increased time and costs.
Moreover, there may be instances where customer requests are not fully communicated to subcontractors, leading to potential issues.
By having everything handled by one company, it allows for prompt and cost-effective responsible rain gutter work.
