The reasons why our company can be entrusted with rain gutter repairs by customers in Nishi-ku, Yokohama

“Our unique strengths in rain gutter repairs that cannot be imitated by other companies”
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 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 sorting of waste materials
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 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 person in charge does not change, whether it’s the sales representative or the construction management representative, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Acquisition of various permits and presence of skilled workers


We have obtained construction industry permits and industrial waste collection and transportation permits!
We have nationally certified sheet metal workers and painting specialists 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!
4. Warranty and Aftercare

In the unlikely event that water leakage is not resolved 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.

Common Problems Related to Rain Gutters

Rain Gutters are facilities that smoothly direct 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.
Let me 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 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
The weight of snow can cause sagging, and strong winds can crack the rain gutters. In some regions, 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
If the slope was not properly set during new construction or remodeling, or if the spacing of the brackets was inappropriate, it can lead to drainage issues and 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 Nishi-ku, Yokohama!
However, with so many contractors, you might find yourself struggling with “I don’t know who to hire…”.
Therefore, when requesting rain gutter replacement or rain gutter repair, 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 if 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 a contractor who is experienced and trustworthy!
You should assess their track record 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 on Google and review sites to find roof repair contractors!
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 requesting their services.
Confirming the presence or absence of a warranty
To prepare for any potential issues or defects after installation, confirm whether they provide a “workmanship warranty”!
Contractors who offer warranties tend to have confidence in their work, making them more trustworthy!
If rain gutter repair or cleaning is 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 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, the costs can be high.
Therefore, when requesting rain gutter replacement, it is essential to obtain estimates from multiple contractors.
The costs for the same rain gutter replacement can vary between contractors, as can the 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 details like “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Confirming if they perform rain gutter repairs and cleaning in-house
Finally, let’s discuss whether we perform the work in-house.
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 communicated 100% to the subcontractor, which can lead to troubles.
By handling everything with one company, we can ensure prompt and cost-effective rain gutter work with accountability.
