Reasons Why Kakeru Koumuten is Chosen for Rain Gutter Repairs in Chuo-ku, Tokyo
The reason our company is entrusted with rain gutter repairs by customers in Chuo-ku, Tokyo is
“Our Strengths in Rain Gutter Repairs That Other Companies Cannot Imitate”
which has received high praise from many customers.
We are absolutely confident in “Cost,” “Quality,” and “Plans” for roof repairs in Chuo-ku, Tokyo, so we would appreciate it if you could compare our estimates with those of other companies.

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 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 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 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 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担当者 does not change, such as 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 on Staff


We have obtained construction industry permits and industrial waste collection and transportation permits!
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 projects for factories and other facilities!
4. Warranty and Aftercare
Rain gutter replacement work comes with a warranty!
If you have any questions about the warranty, please click the image above!
In the unlikely event that water leakage does not improve 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 snow damage threatening to drop the rain gutters, 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 processing depending on the site, we regularly provide skill enhancement training for all staff to ensure they can respond effectively.
Subsidies and Grants That May Apply for Rain Gutter Cleaning and Repair in Chuo-ku, Tokyo補助金、助成金

Common Problems with 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 is a problem 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.
Let me explain the main causes of troubles related to rain gutters.
1. Clogs 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 cause blockages by hindering drainage.
If clogs in the rain gutter are left unattended, the sound of overflowing water can become noise and the weight of rainwater accumulating in the rain gutter can cause it to warp.
It is essential to regularly clean the rain gutters or promptly clean them if you notice any clogs!
2. Aging and UV Damage
Rain gutters are constantly exposed to the outside air, which means they are continually 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”.
If deterioration is due to aging, partial replacement may be difficult and there is a high possibility of immediate damage, so we strongly recommend complete replacement of the rain gutter!
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 replacement or repair of the rain gutters!
4. Improper installation during setup
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 Chuo-ku, Tokyo!
However, with so many contractors, you might struggle with “not knowing which one to choose..”.
Therefore, when requesting rain gutter replacement or repair, be sure to check the following 4 points.
● Have extensive experience in rain gutter repair and replacement
● Confirm the existence of a warranty
● Obtain multiple estimates for rain gutter replacement (at least 3 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 repair
About 10-20% of rain gutter troubles are caused by poor workmanship during installation.
To prevent troubles, it is important to hire a reliable contractor with experience!
You should refer to the construction results and reviews on our company website to make your decision.
Checking achievements on social media platforms like Instagram can also be effective!
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 might be safer to refrain from hiring them.
Check for warranty availability
In case of any poor workmanship or defects after construction, make sure to confirm whether they provide a “construction warranty”!
Contractors that offer warranties are usually confident in their work, making them more trustworthy!
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 leaks during rainy weather, and if there are any issues, contact the contractor immediately, as it will be easier to communicate shortly after the work is done!
Get estimates from multiple contractors for rain gutter replacement (at least 3 companies)
Since rain gutter replacement 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, warranties, and after-service may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To hire your desired repair contractor at a lower price, obtaining estimates from several contractors is indispensable.
When comparing estimates, be sure to check not only the costs but also the details such as
“types of rain gutters” and “spacing of support brackets” for a thorough comparison!
Confirm whether they perform rain gutter repairs and cleaning in-house
Finally, check if they perform the work in-house.
If a sales company investigates and then requests a subcontractor, it can take more time and cost.
Moreover, there may be instances where your 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 done quickly and cost-effectively.
Kakeru Koumuten conducts all work from existing rain gutter inspections to actual repairs in-house!
