Reasons Why Kakeru Koumuten is Chosen for Rain Gutter Repairs in Konan-ku, Yokohama
One reason our company is trusted with rain gutter repairs by customers in Konan-ku, Yokohama is
that we have a base in Yokohama City,
and we have unique strengths in rain gutter repairs that cannot be imitated by other companies,
which have received high praise from many customers.
We have absolute confidence in our “costs,” “quality,” and “plans” for roof repairs in Konan-ku, Yokohama, so we would appreciate it if you could compare our estimates with those of other companies.

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 performed by our own team, 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 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 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 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 welcome competitive estimates!
3. Acquisition of various permits and presence of 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
Our rain gutter replacement work comes with a warranty!

5. Flexible and Prompt Response
In case of emergencies, such as rain gutters being dislodged due to a typhoon or 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 the tasks.

Common Problems Related to Rain Gutters

Rain Gutter refers to the equipment that smoothly directs rainwater falling from the roof to the ground.
While it may not be something you think about often, 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 troubles and stress with neighbors.
Let me explain the main causes of problems related to rain gutters.
1. Clogging 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 you leave the clog in the rain gutter unattended, the sound of overflowing water from the rain gutter can become a noise nuisance and the weight of the rainwater accumulated in the rain gutter can cause it to warp.
If you regularly clean your rain gutters or notice a blockage, early cleaning is necessary!
2. Aging and UV Damage
Rain gutters are constantly exposed to the outside air, and are continuously affected by UV rays and rain and wind.
This can lead to “cracks in the rain gutters,” “rust on the support brackets,” and “thermal deformation of the rain gutters”.
In cases of aging damage, partial replacement can 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
Rain gutters can bend under the weight of snow or break due to strong winds. In some regions, the impact of falling snow can also deform or damage the rain gutters.
Depending on sunlight and location, if the building is within 15 to 20 years old, it may be possible to maintain the gutters with partial replacement or repairs!
4. Improper Installation
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 bending. This may not be noticeable at first 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 Konan-ku, Yokohama!
However, with so many options, you might struggle with “not knowing which one to choose…”.
Therefore, when requesting rain gutter replacement or repair, be sure to check the following four points:
● Have extensive experience in rain gutter repair and replacement
● Confirm whether a warranty is available
● 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 4 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 contractor who is experienced and trustworthy!
You need to refer to the contractor’s website for their work achievements and reviews to make a judgment.
It may also be effective to check their achievements on social media platforms like Instagram!
It is also effective to look at reviews on Google and review sites when considering 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 making a request.

Check for the presence of a warranty
In case of poor workmanship or defects occurring after the installation, make sure to confirm whether they provide a “work 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 check if rainwater overflows.
After rain gutter cleaning or repairs, 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, 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 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
“the type of rain gutter” and “the spacing of support brackets” for a thorough comparison!
Check if 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 requests a subcontractor, it can lead to additional time and costs.
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 carried out quickly and cost-effectively.
