Reasons Why Kakeru Koumuten is Chosen for Rain Gutter Repairs in Aoba-ku, Yokohama
The reason customers in Aoba-ku, Yokohama trust us with their rain gutter repairs is
“Our Unique Strengths in Rain Gutter Repairs That Others Cannot Imitate”
which has received high praise from many customers.
In roof repairs in Aoba-ku, Yokohama,
“Cost,” “Quality,” and “Plans” are our absolute strengths,
so we would appreciate it if you could compare our estimates with those of other companies.
Because we are confident, we welcome competitive estimates!
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 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 cut 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 waste separation
In rain gutter repairs, various waste materials such as PVC and metal are generated. While most contractors dispose of them all together, 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 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 permits for construction work and industrial waste collection and transportation!
We have 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!
If you are curious about the warranty, please click the image above!
In the unlikely event that water leakage is not improved 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 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 these tasks.

| We received an inquiry from a customer living in Tokyo who said, “Water leaks from the rain gutter when it rains.” The customer obtained estimates from four companies, including ours, and chose us because we were “the cheapest” for the work! |
Our Proposal
Upon visiting the site, we found damage at the corners and joints of the rain gutter, which was causing water leakage. The existing rain gutter was a discontinued product, making partial replacements impossible, so we proposed a complete replacement of the rain gutter.
The Panasonic/PC50 used in this project features internal brackets, making it more durable and less prone to distortion compared to other rain gutters.
Common Issues Related to Rain Gutters

Rain Gutter is a facility that smoothly directs rainwater from the roof to the ground.
Although you may not think about it often, if there are issues 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.
Therefore, let’s explain the main causes of troubles related to rain gutters.
1. Clogging from Debris and 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, causing clogs that hinder drainage.
If you leave a blockage in the rain gutter unattended, it can lead to the sound of overflowing water becoming a nuisance or deformation of the rain gutter due to the weight of accumulated rainwater.
It is essential to regularly clean the rain gutters, or if you notice a blockage, prompt cleaning is necessary!
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 and there is a high likelihood of immediate damage, so we recommend complete 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 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 is inappropriate, it can lead to drainage issues or sagging. This may not be visually apparent and can go unnoticed for a long time.
If you are still within the warranty period, it is advisable to request adjustments or repairs promptly!
How to Choose a Rain Gutter Repair Contractor
There are many rain gutter repair contractors available in Higashimurayama City, Tokyo!
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 the presence of a warranty
● Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
● Check if the company conducts 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 repairs
About 10-20% of rain gutter issues are caused by poor workmanship during installation.
To prevent troubles, it is important to hire a contractor who is experienced and trustworthy!
You should refer to the company’s website for their track record and customer 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 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, the reviews are trustworthy.
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Confirm the presence of a warranty
In case of any construction defects or issues occurring after the work is completed, make sure to check if they provide a “construction warranty”!
Contractors who offer warranties are usually confident in their work, making them more trustworthy companies!
If rain gutter repairs or cleaning are performed, make sure to have before-and-after photos taken of areas that are not visible from below!
For rain gutter cleaning, request 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 for smooth communication since it will be shortly after the work is completed!
Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
Since the replacement of rain gutters 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 may vary between contractors, as well as the warranties and after-sales services they offer.
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 finer details such as “types of rain gutters” and “spacing of support brackets”!
Confirm whether the company performs rain gutter repairs and cleaning in-house
Finally, it’s important to check if the work is done by the company itself.
If a sales company conducts an investigation and then requests a subcontractor, it can lead to additional time and costs.
Moreover, there may be instances where customer requests are not fully communicated to the subcontractor, potentially leading to troubles.
By having everything handled by one company, we can ensure prompt and cost-effective responsible rain gutter work.
