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 five bases including material storage and showrooms within Kanagawa Prefecture.
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 performing scaffolding work in-house rather than outsourcing it, we can also reduce the 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. This can lead to a longer construction period, which means higher “labor costs” and “transportation costs”.
In our case, since everything is done in-house, we can complete “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling” in as little as one day!
Therefore, it is possible to significantly reduce costs by shortening the construction period!
We have enough scaffolding materials for approximately 50 houses!
Storage of materials in our large in-house warehouse

This is the warehouse where we store roofing materials and rain gutters.
Since we have our own warehouse, we canpurchase materials at a lower cost by ordering a large quantity at once!
Additionally, we always have rain gutter materials in stock, allowing us to provideswift responses for emergency rain gutter repairs!
In-house waste separation
This is the storage area for waste materials.
In rain gutter repairs, various materials such as PVC and metal generate waste.
While most contractors dispose of them all together, by sorting and recycling waste materials, significant cost reductions on waste disposal can be achieved.
Exterior Renovation Dedicated Showroom


This is our 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 complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd., 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 warmly welcome competitive estimates!
3. Various Permits Obtained & Skilled Workers Available


We have obtained permits for construction work and 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 work for factories and other facilities!

Common Problems Related to Rain Gutters

Rain Gutters are facilities that smoothly direct rainwater falling 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 us 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 onto 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 noise and the weight of accumulated rainwater can cause distortion in the rain gutters.
It is essential to regularly clean the rain gutters or promptly clean them if you notice any clogs!
2. Aging and UV Damage
Rain gutters are constantly exposed to the outside elements, 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 prone to quick damage, so we strongly recommend a 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 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 replacement or repair of the rain gutters!
4. Construction Defects at Installation
If the slope was not properly set or the spacing of the brackets was inappropriate during new construction or renovation, 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, Sagamihara!
However, with so many contractors, you might struggle with “not knowing which one to choose..”.
Therefore, when requesting rain gutter replacement or repair, make sure 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 they perform rain gutter repairs in-house
By confirming the above four points, you will be able to choose a reliable contractor.
Check for Extensive Experience in Rain Gutter Repair
About 10-20% of rain gutter troubles are caused by construction defects during installation.
To prevent issues, it is important to hire a reliable contractor with experience!
You should refer to the construction results and reviews on the company’s website to make your judgment.
Checking 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 serves as a trustworthy review source.
If there are many negative reviews or no reviews at all, it may be wise to refrain from making a request.

Check for warranty availability
In case of construction defects or issues after installation, make sure to confirm whether they provide a “construction warranty”!
Contractors who offer warranties are usually confident in their work, making them more trustworthy companies!
If you have rain gutter repairs or cleaning done, 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 repairs, check for 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!
Get 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-service may vary between contractors.
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 details such as
“types of rain gutters” and “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 handle the work in-house.
If a sales company investigates and then requests a subcontractor, it will take more time and cost.
Moreover, there may be cases where customer requests are not fully communicated to the subcontractor, leading to potential troubles.
By having everything handled by one company, responsible rain gutter work can be done quickly and cost-effectively.
Kakeru Koumuten conducts everything from existing rain gutter inspections to actual repairs in-house!
