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 reduce the costs associated with scaffolding work.
In cases where temporary scaffolding is needed for partial rain gutter repairs or replacements, it typically takes at least “3 days of construction period” for “scaffolding assembly,” “rain gutter repair,” and “scaffolding dismantling.” 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 1 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 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.
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 specialists on staff, and we are confident in our construction techniques.
We are also capable of handling large-scale rain gutter installations for factories and other facilities!
4. Warranty and Aftercare Maintenance
Rain gutter replacement work comes with a warranty!

5. Flexible and Prompt Response

We will respond as quickly as the same day!
6. Human Resource Development
To enhance skills, we create various building models ourselves and conduct practical training.

Our Proposal
Since the existing rain gutter was a discontinued product, we had 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 Problems Related to Rain Gutters

Rain Gutter is afacility that smoothly directs rainwater falling from the roof to the ground.
You may not pay much attention to it on a daily basis, but if there is a problem with the rain gutter, it can cause rainwater to run down the exterior walls, leading to dirt and moss, and accelerate the deterioration of the building.
Additionally, water leaking from damaged areas can create noise as it hits the ground, which can lead to troubles and stress with neighbors.
Therefore, let me explain the main causes of troubles 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 and obstruct drainage, causing clogs.
If you leave rain gutter clogs unattended, the sound of overflowing water from the rain gutter can become a nuisance and the weight of accumulated rainwater can cause deformation in the rain gutter.
It is necessary to regularly clean the rain gutters or to perform cleaning promptly if you notice a clog!
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 the support brackets,” and “thermal deformation of the rain gutter”.
In cases of aging damage, partial replacement may be difficult or 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 15 to 20 years old, it may be possible to manage with partial replacement or repair of the rain gutters!
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 and 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 Miura 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, make 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 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 assess based on the company’s website showcasing their work and customer reviews.
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 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 “work warranty”!
Contractors who offer warranties tend to have confidence in their work, making them more trustworthy companies!
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, request 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 promptly 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 installing temporary scaffolding is necessary for rain gutter replacement, 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, warranties, and after-sales services may vary between contractors.
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, check not only the costs but also details such as “type of rain gutter” and “spacing of support brackets” for a thorough comparison!
Checking if the company performs rain gutter repairs and cleaning in-house
Finally, let’s talk about 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 provide responsible rain gutter work that is quick and cost-effective.

Features of Miura City, Kanagawa Prefecture
Miura City, Kanagawa Prefecture, is located at the southern tip of the Miura Peninsula and is a nature-rich city surrounded by the sea on three sides. To the west is Sagami Bay, to the east is the Uraga Channel (Tokyo Bay), and to the south faces the Pacific Ocean, with Jogashima floating at the southern end. The Miura Hills spread throughout the city, characterized by plateaus at an elevation of 40 to 60 meters and a hilly terrain.
The climate is warm throughout the year due to the influence of the Kuroshio Current, with relatively cool summers and mild winters, making it a comfortable environment. Compared to Tokyo, summer and winter temperatures are about 1 degree lower, and snowfall is rare, allowing for a pleasant living experience.
For transportation access, the Keihin Kyuko Electric Railway Kurihama Line runs through the city, with two stations: Miura Kaigan Station and Misakiguchi Station. Since Misakiguchi Station is the starting station, there is the advantage of being able to sit during morning commutes and school trips. It takes about 70 minutes to reach Shinagawa Station and about 50 minutes to Yokohama Station from Miura Kaigan Station. Additionally, Keihin Kyuko buses operate within the city, making it convenient to travel to major tourist spots and living hubs.
