which have received high praise from many customers.

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 centered around Kanagawa Prefecture 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 usually 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 canpurchase materials at a lower cost!
Additionally, we always have rain gutter components in stock, allowing us to provideswift responses for emergency rain gutter repairs!
In-house waste separation
During 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 ensured.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Obtaining various permits and having skilled workers


We have obtained construction industry licenses and permits for industrial waste collection and transportation!
We have certified sheet metal 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!

Common Issues Related to Rain Gutters

Rain Gutter is a system that plays the role of smoothly directing rainwater that falls on the roof to the ground.
You may not usually pay much attention to it, but if there is a problem 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.
Let me explain the main causes of troubles related to rain gutters.
1. Clogs from debris and fallen leaves
Many issues with rain gutters stem from blockages.
Leaves, dust, and small branches that fall on the roof can flow into the rain gutters, obstructing drainage and causing clogs.
If you leave a blockage in the rain gutter unattended, it can lead to the sound of overflowing water becoming noise or deformation of the rain gutter 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 elements, they are continually 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”.
If aging is the cause, partial replacement may be difficult or may lead 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 also 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. Improper Installation
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 Chuo-ku, Sagamihara!
However, with so many contractors, you might find yourself struggling 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 performs rain gutter repairs in-house
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 crucial to hire an experienced and trustworthy contractor!
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 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, the reviews are generally trustworthy.
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Confirm whether a warranty is provided
In case of any construction defects or issues after the work is completed, make sure to check if they offer a “construction warranty”!
Contractors who provide warranties tend to have confidence in their work, making them more trustworthy!
If rain gutter repairs or cleaning are performed, ask for 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 cleaning or repairing the rain gutters, check for any leaks during rainy weather, and if there are any issues, contact the contractor immediately for smooth communication since it is shortly after the work was 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 services from your preferred repair contractor at a lower cost, obtaining estimates from multiple contractors 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 a thorough comparison!
Confirming Whether Rain Gutter Repairs and Cleaning Are Done In-House
Finally, this is about whether the work is done in-house.
If a sales company investigates and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there are cases where customer requests are not 100% communicated to the subcontractor, which can lead to troubles.
By having everything handled by one company, we can provide responsible rain gutter work that is quick and cost-effective.
