Reasons Why Kakeru Koumuten is Chosen for Rain Gutter Repairs in Aoba-ku, Yokohama
The reason our company is trusted with rain gutter repairs by customers in Aoba-ku, Yokohama is
“Our Unique Strengths in Rain Gutter Repairs That Cannot Be Imitated by Other Companies”
which has received high praise from many customers.
We have absolute confidence in terms of “Cost,” “Quality,” and “Plans” for roof repairs in Aoba-ku, Yokohama,
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 prepared 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 set up scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs on scaffolding work.
In cases where partial rain gutter repairs or replacements require temporary scaffolding, 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. 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 its complete in-house construction.
By having Kakeru Koumuten Co., Ltd. handle everything from inquiries to project completion in a consistent manner, we can 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 sales and construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Various Permits Obtained & Skilled Workers Available


We have obtained permits for construction work and industrial waste collection and transportation!
We have 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
Rain gutter replacement work comes with a warranty!
If you are curious about the warranty, please click on 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 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 conduct skill enhancement training for all staff to ensure they can handle these tasks.

Our Proposal
Since the existing rain gutter was a discontinued product, it was necessary to replace all of the rain gutters. However, because the damage was caused by wind, we suggested utilizing fire insurance.
The Panasonic/PC50 used in this construction has a feature where it contains metal fittings inside, 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 falling from the roof to the ground.
You may not usually pay much attention to it, but 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, we will explain the main causes of troubles related to rain gutters.
1. Clogs from Debris and Leaves
Many issues with rain gutters are due to 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 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 necessary to regularly clean the rain gutters or to perform cleaning promptly if you notice a blockage!
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”.
If the cause is aging, partial replacements may be difficult and there is a high possibility of immediate damage, 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 particular regions, the impact of falling snow can deform or break the rain gutters.
Depending on sunlight exposure and location, if the building is within 15 to 20 years old, it may be possible to manage with partial rain gutter replacements or repairs!
4.Improper Installation at the Time of Setup
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 or sagging. This may not be easily noticeable and can go unnoticed for a long time.
If it is 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 Atsugi City, Kanagawa Prefecture!
However, with so many contractors, you might struggle with “not knowing which one to choose..”.
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.
Check 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 an experienced and trustworthy contractor!
You need to judge based on the construction achievements and reviews on their company website.
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, 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 requesting their services.
Confirm the presence or absence of a warranty
In case of any defects or issues after construction, let’s check if they provide a “construction 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, request a water flow test to check if rainwater overflows.
After rain gutter cleaning or repair, check for any leaks during rainy weather, and if there are any issues, contact the contractor immediately as the communication will be smoother shortly after the work is done!
Obtain 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, warranties, and after-sales services can vary between contractors even for the same rain gutter replacement work.
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 “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Check if they perform rain gutter repairs and cleaning in-house
Finally, let’s discuss whether we conduct our own construction work.
When a sales company investigates and then requests a subcontractor, it can lead to extra time and costs.
Additionally, there are times when customer requests are not communicated 100% to the subcontractor, which can lead to troubles.
By handling everything in-house, we can provide prompt and cost-effective rain gutter work with accountability.
Kakeru Koumuten Co., Ltd. conducts everything from existing rain gutter inspections to actual repairs in-house!
