“Reasons why Kakeru Koumuten is chosen in Koto-ku, Tokyo” and more
For customers living in Koto-ku, Tokyo, who are considering skylight replacement,
this will definitely be helpful, so please take a look!
To conclude, the most important thing to consider when planning skylight work is
“multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors covering Koto-ku, Tokyo!
Reasons why Kakeru Koumuten is chosen for skylight work in Koto-ku, Tokyo
The reasons why our company is entrusted with skylight repairs in Koto-ku, Tokyo
include the fact that “Kakeru Koumuten is a roofing company in Tokyo,”
but also “our unique approach to skylight replacement work that cannot be imitated by other companies”
, which has received high praise from many customers.
“cost, quality, and plans” are our absolute strengths,
1. Equipment Specialized in Exterior Renovation
At Kakeru Koumuten Co., Ltd., we have prepared the following warehouses and material storage areas to provide low-cost, high-quality exterior renovations such as skylight installation.
We have established five bases for material storage and showrooms.
In-house Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for skylight installation, allowing us to set up scaffolding ourselves.
By not outsourcing scaffolding work and using our own scaffolding team, we can cut costs on scaffolding work and respond quickly in emergencies.
We have scaffolding materials for approximately 50 single-family homes!
Storage of Materials in Our Large In-house Warehouse
We store materials used for exterior renovations.
By ordering a large quantity of materials at once, we canprocure materials at a lower cost!
Additionally, we always have stock available, allowing us torespond quickly in emergencies!
In-house Waste Separation
During skylight construction, various waste materials such as roofing materials, glass, and wood are generated.
While most contractors dispose of them all together, we can significantly cut waste disposal costs by separating and recycling the waste materials.
Showroom Dedicated to Exterior Renovations
In our showroom, not only can you have meetings, but you can also
directly check the actual roofing materials and colors.
You can also perform color simulations for exterior painting and check heat insulation properties using a heat insulation testing machine!
2. Complete in-house construction for skylight installation
One of Kakeru Koumuten’s major strengths is our complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten in a consistent manner, allowing us to keep costs down while providing high-quality skylight installations.
Additionally, one representative will handle everything from the estimate to the completion of the work.
Since the person in charge does not change, whether it’s the sales representative or the construction management representative, smooth communication is possible.
We can handle everything from temporary scaffolding setup to exterior painting, roofing work, and exterior cover work with complete in-house construction!
Since skylight installation involves dismantling or removing roofing materials, doing it simultaneously with roof replacement or cover work can significantly reduce costs!
3. Various permits obtained and skilled workers on staff
We have obtained construction industry licenses and permits for industrial waste collection and transportation!
We have nationally 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 roofing projects such as those for factories!
We have qualified asbestos supervisors and asbestos surveyors on staff, allowing us to handle asbestos-containing roofing materials and conduct preliminary surveys.
4. Warranty and Aftercare
The skylight replacement work comes with a warranty! Aftercare is available every year, and we send out notification DM each year.
5. Flexible and Prompt Response
Our company is equipped to handle various troubles and situations related to skylights.
Even if you cannot access the roof at high places, we can respond using a drone!
During leak investigations, we can also conduct surveys using a thermal imaging camera, which helps in identifying the cause of leaks!
We will respond according to your wishes.
We also accept emergency measures for sudden leaks from skylights!
6. Human Resource Development
We are creating various roof models to improve our skills and conducting practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education to ensure that all staff can respond effectively.
Possible subsidies and grants for skylight construction in Koto-ku, Tokyo
In Koto-ku, Tokyo, there are potential subsidies available when carrying out skylight construction!
For details, please contact our company or your local government!
Child-Rearing Green Housing Support Project
Eligible Participants
Households with children (households with children under 18) and young couples are eligible for new construction or purchase of energy-efficient homes, or energy-efficient renovations of existing homes. For new construction, the builder or purchaser is eligible, and for renovations, the contractor who orders the work is eligible for the subsidy.
Requirements
For new homes, it is necessary to meet high energy efficiency standards set by the government, such as ZEH standards. For renovations, the work must improve the energy efficiency of the home through insulation upgrades or the introduction of energy-efficient equipment. In both cases, it is necessary to contract with a registered business and carry out the work within the specified period.
Maximum Subsidy Amount
For new construction, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen, depending on the performance category of the home. For renovations, the maximum subsidy per unit ranges from 400,000 yen to 600,000 yen, depending on the content of the work. In either case, even if multiple works are carried out, the total subsidy cannot exceed this maximum amount.
Subsidy Rate
This project does not provide a subsidy based on a certain percentage of the construction cost; instead, a predetermined “fixed subsidy” is provided based on the content of the work and performance category. Therefore, in effect, the government bears part of the construction cost.
For more details, please see here!
Advanced Window Renovation Project
Eligible Participants
Owners of existing homes (single-family homes and apartment buildings) who are carrying out insulation renovation work on windows and openings are eligible. The actual subsidy application process is carried out by registered “window renovation contractors” with the government, and the granted subsidies are fully refunded to the homeowners through discounts on construction costs.
Requirements
The eligible renovations include the installation of interior windows, replacement of exterior windows, and glass replacement aimed at improving insulation performance in existing homes. It is necessary to use products that meet the insulation performance standards set by the government and to enter into a construction contract with a registered window renovation contractor. Additionally, the total subsidy amount must be 50,000 yen or more, and the work must start and be completed within the specified construction period.
Maximum Subsidy Amount
The maximum subsidy is 2 million yen per household. Even if multiple windows are renovated, the total subsidy that can be received for the same residence will be up to this maximum amount.
Subsidy Rate
The subsidy rate is approximately equivalent to half of the construction costs. The actual subsidy amount is set at a fixed rate based on the type of window (inner window, outer window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction costs.

Customer Feedback
Advantages and Disadvantages of Skylights
Advantages of Skylights
High Light Transmission
First, the advantage of skylights is their high light transmission.
When natural light enters the room, it creates a sense of openness, making you feel more comfortable.
Energy Savings
This also contributes to high light transmission, allowing you to save on electricity costs due to the presence of natural light. It reduces the need to turn on lights during the day, making it energy-efficient.
Good Ventilation
By installing a skylight, you can open and close it, improving ventilation.
Warm air rises, enhancing airflow as well.
High Privacy
In areas with closely built houses, large windows can make the interior visible. However, with skylights installed on the roof, your privacy is maintained.
Disadvantages of Skylights
Risk of Leaks
The biggest concern when installing a skylight is the risk of leaks. Since it involves opening up the roof, there is always some risk of water leakage.
However, with proper installation and regular maintenance, the risk can be minimized significantly.
Regular Maintenance Required
Skylights need maintenance every 5 to 10 years to prevent leaks. While maintenance may seem troublesome, it is recommended to do it regularly to avoid damage to the interior and wooden parts caused by leaks.
Noise from Rain
Since skylights are installed directly on the roof, the sound of raindrops hitting the glass can easily be transmitted indoors. This can be particularly noticeable during heavy rain or storms.
However, this is not strongly felt with all skylights. By choosing double-glazed glass or products with high sound insulation, the sound of rain can be reduced.

Skylight Glass Replacement Work – Construction Steps
1. Remove the surrounding materials of the skylight
First, we will remove the cover materials and securing materials around the skylight. These materials will be reused, so we will take them off carefully.
2. Protection
We will protect the area around the skylight indoors.
We will take precautions to ensure that no debris falls indoors.
3. Removal of Existing Glass
Next, after removing the cover materials, we will take out the existing glass.
4. Installation of New Glass
Once the existing glass is removed, we will install the new glass. We will be careful to ensure that the glass does not break during installation, just as we were during removal.
5. Waterproofing Treatment
When replacing the skylight glass, waterproofing treatment may be necessary.
We will perform waterproofing treatment around the glass using butyl tape and other materials.
6. Restoration of Materials and Sealing
We will reattach the covers and fasteners that held the glass in place.
It is important to confirm that the fasteners are securely in place, as using the wrong installation method for the skylight can lead to leaks.
We will perform waterproofing treatment around the frame with sealing.
How to Choose a Skylight Contractor
There are many skylight contractors in Tokyo, and you may be unsure which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, let’s check the following 5 points.
● Have extensive experience in skylight work
● Confirm if they can also handle roof work
● Check for warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm if they perform roof renovations in-house
By confirming the above 5 points, you will be able to choose a reliable contractor.
Have Extensive Experience in Skylight Work
Skylight contractors often have websites where they showcase their work experience.
Additionally, if they provide detailed explanations of repair work with photos, it can give you peace of mind as a reference when you actually request repairs.
If you are worried about whether the contractor you are about to hire will respond well, choose one with extensive repair experience.
It is also effective to look at reviews of skylight contractors on Google and review sites!
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Kakeru Koumuten Co., Ltd. specializes in exterior work, so we receive many requests for skylight replacement work.
Confirm if They Can Handle Roof Work
Since skylights are installed on roofs, roof work is often involved.
If the contractor lacks knowledge about roofs or cannot handle roof work, it may lead to leaks after installation or high construction costs, resulting in potential troubles.
Moreover, since skylight replacement or removal may require partial dismantling of the roof and restoration, performing roof overlay work or re-roofing at the same time can significantly reduce costs!
Our company specializes in roofing work, so we can propose the optimal plan tailored to your needs for roofing work associated with skylight installation.
Check for warranties and after-sales maintenance
When choosing a skylight contractor, let’s confirm the availability of warranties.
If a leak occurs after the skylight installation, having a leak warranty from the contractor ensures that repairs can be made at no cost, providing peace of mind!
Additionally, companies that offer warranty periods demonstrate confidence in their work, making it a criterion for selecting a contractor!
Warranty periods vary by contractor and the nature of the work, but typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Moreover, some contractors offer after-sales services in addition to warranties, so be sure to check if the contractor you are considering has warranties and after-sales services.
Kakeru Koumuten Co., Ltd. sends out annual DM for after-sales maintenance, allowing for yearly inspections.
For simple repairs like partial sealing, we provide services free of charge.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting skylight installation, obtain estimates from multiple contractors.
Even for the same repair or replacement work, costs and warranties or after-sales services may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, it is essential to obtain estimates from multiple companies.
When comparing estimates, consider not just the costs, but also
“Items in the estimate”
“Materials and quality of glass”
“Verification of processes”
and make a detailed comparison! If the quality of auxiliary materials is low or if processes are skipped, costs can be reduced, so avoid making decisions based solely on price!
Check if the contractor performs the work in-house
There are various construction methods for skylight repair plans, including full replacement, roof overlay (cover method), and partial repairs!
The plan details will vary depending on the actual state of deterioration and the customer’s preferences.
If you choose a contractor that completely outsources skylight repair work, they may lack knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary work. There are cases where customers wanting to keep costs down are suggested to replace the skylight instead of a partial repair that would suffice.
Additionally, since they need to investigate and then request a subcontractor, both time and costs can increase unnecessarily.
By having the knowledge and experience to perform the work in-house, we can provide responsible construction while keeping costs down.
Moreover, with contractors that outsource completely, one disadvantage is that their response to emergencies, such as post-construction troubles, tends to be slow.
