The reasons why our company is entrusted with rain gutter repairs by customers in Aoba-ku, Yokohama include
“Having a base in Yokohama” as one of the reasons,
“Our strengths in rain gutter repairs that cannot be imitated by other companies”
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 exterior renovations such as rain gutter repairs more affordably and more quickly.
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 ourselves.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can reduce the costs associated with scaffolding work.
In cases where temporary scaffolding is needed for partial rain gutter repairs or replacements, it usually takes at least “scaffolding setup,” “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 setup,” “rain gutter repair,” and “scaffolding dismantling” in as little as one day!
Since everything is done in-house, we can significantly reduce costs by shortening the construction period!
We have scaffolding materials sufficient 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 can purchase 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 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 color 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 project.
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 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 work for factories and other facilities!
4. Warranty and Aftercare
Rain gutter replacement work comes with a warranty!

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 partially detached 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.
Since rain gutter repairs and replacements require various modifications depending on the site, we regularly provide skill enhancement training for all staff to ensure they can handle different situations.

Common Issues Related to Rain Gutters

Rain Gutter refers to the system that smoothly directs rainwater falling from the roof to the ground.
You may not often think about it, but if there is a problem with the rain gutter, rainwater can cause dirt and moss to accumulate on the exterior walls, accelerating the deterioration of the building.
Additionally, water leaking from damaged areas can create noise as it hits the ground, leading to potential disputes or stress with neighbors.
Let us explain the main causes of issues 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 clogs in the rain gutter are left unattended, the sound of overflowing water can become a nuisance, and the weight of accumulated rainwater can cause the rain gutter to warp.
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 air, which means they are 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 the cause is due to aging, partial replacement may be difficult and 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 bending, and strong winds can crack the rain gutters. In some regions, the impact of falling snow can deform or break the rain gutters.
Depending on sunlight 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 the time of installation
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 and sagging. This may not be obvious at first glance 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 Tsuzuki-ku, Yokohama!
However, with so many contractors, you might struggle with “not knowing who to trust…” when it comes to choosing a contractor.
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 the existence of a warranty
● Obtain multiple estimates for rain gutter replacement (at least three companies)
● Check if they perform rain gutter repairs in-house
By confirming these four points, you will be able to choose a reliable contractor.
Check if they have extensive experience in rain gutter repairs
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 experience!
You should refer to the construction achievements and reviews on their official website to make a judgment.
Checking their achievements on social media platforms like Instagram can also be effective!
It can also be 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 remove 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 hiring them.
Confirm whether there is a warranty
In case any defects or issues occur after construction, make sure to check if they provide a “construction warranty”!
Contractors who offer warranties are usually confident in their work, making them more trustworthy!
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, request a water flow test to ensure that rainwater does not overflow.
Check for any leaks from the rain gutters during rainy weather after cleaning or repairs, 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, 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-sales services may vary by contractor.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To hire your desired repair contractor at a lower price, obtaining estimates from several companies is indispensable.
When comparing estimates, be sure to check not only the costs but also
the “type of rain gutter” and “spacing of support brackets,” and compare these details!
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 additional time and costs.
Moreover, there may be cases where customer requests are not fully communicated to subcontractors, leading to potential issues.
By handling everything with one company, responsible rain gutter work can be done quickly and cost-effectively.
