Reasons Why Kakeru Koumuten is Chosen for Rain Gutter Repairs in Tachikawa City, Tokyo

“Our Unique Strengths in Rain Gutter Repairs That Others Cannot Imitate”
which has received high praise from many customers.
In roof repairs in Tachikawa City, Tokyo,
“Cost,” “Quality,” and “Plans” are our absolute strengths,

1.Facilities Specialized in Exterior Renovation
At Kakeru Koumuten Co., Ltd., we have prepared 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, including 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 performing 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 procure 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 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. 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 can also handle 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 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 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 technical training to ensure that each staff member can respond effectively.

| Inquiry Details |
| We received an inquiry from a customer living in Tokyo saying, “When it rains, water leaks from the rain gutter.” The customer obtained estimates from four companies, including ours, and chose us because we offered the “lowest price” 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 leaks. The existing rain gutter was an obsolete product, with both the eaves gutter (horizontal gutter) and vertical gutter no longer in production, making partial replacement impossible. Therefore, we proposed a complete replacement of the rain gutter.
For this project, we used Panasonic’s PC50, which has metal fittings inside, making it more durable and resistant to deformation compared to other rain gutters.
Common Issues Related to Rain Gutters

Rain Gutter is a system that plays a role in smoothly directing rainwater from the roof to the ground.
You may not think about it often, 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 fallen leaves
Many issues with rain gutters stem from blockages. Leaves, dust, and small branches that fall onto the roof can flow into the rain gutters, obstructing drainage and causing clogs.
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 to clean them promptly if you notice a blockage!
2.Aging and UV Damage
Since rain gutters are constantly exposed to the outside air, 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 or prone to quick 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 crack due to strong winds. In some regions, the impact of falling snow can deform or damage 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 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 was inappropriate, it can lead to drainage issues or 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 Tachikawa, Tokyo!
However, with so many contractors, you might find yourself struggling with “not knowing who to hire..” when it comes to choosing a contractor.
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 whether a warranty is provided
● Obtain estimates from multiple contractors for rain gutter replacement (at least three companies)
● Check if the company performs rain gutter repairs in-house
By confirming the above four points, you can choose a reliable contractor.
Check for 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 crucial to hire a contractor with extensive experience and reliability!
You should refer to the company’s website for their track record and customer reviews to make your judgment.
Checking their achievements on social media platforms like Instagram can also be effective!
It is also effective to look at reviews on Google and review sites to find roofing repair contractors!
A recommended review site is “Google”.
Since it is difficult to remove low ratings, the reviews are generally trustworthy.
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Confirm whether a warranty is provided
In case of any construction defects or issues occurring after the work, make sure to check if they offer a “construction warranty”!
Contractors who provide a warranty are usually confident in their workmanship, making them more trustworthy!
If rain gutter repairs or cleaning are performed, ask for before-and-after photos of areas that are not visible from below!
For rain gutter cleaning, ensure they perform a water flow test to check if rainwater overflows.
After rain gutter cleaning or repairs, check for any leaks during rainy weather and contact the contractor immediately if there are any issues, as this will facilitate smooth communication shortly after the work is done!
Obtain estimates from multiple contractors for rain gutter replacement (at least three 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.
Even for the same rain gutter replacement work, costs may vary between contractors, and warranties and after-sales services may differ as well.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred 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 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 confirm whether the work is done in-house.
If a sales company investigates 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 issues.
By handling everything with one company, we can ensure prompt and cost-effective rain gutter work with accountability.
