Reasons why Kakeru Koumuten is chosen for skylight work in Aoba-ku, Yokohama
The reasons why we are entrusted with skylight repairs in Aoba-ku, Yokohama
include the fact that “Kakeru Koumuten is a roofing company in the Tokyo area,”
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 plan” are our absolute strengths,
1. Equipment Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage areas to provide low-cost, high-quality exterior renovations such as skylight installations.
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 installations, allowing us to assemble scaffolding in-house.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can cut costs on scaffolding work and respond quickly in emergencies.
We have scaffolding materials for approximately 50 detached houses!
Storage of Materials in Our Large Warehouse
We store materials used for exterior renovations.
By ordering a large quantity of materials at once, we can purchase materials at a lower cost!
Additionally, we always have stock available, allowing us to respond 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, by separating and recycling waste materials, we can significantly cut down on waste disposal costs.
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 inquiries 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 project completion.
Since the same person is responsible for sales and construction management, smooth communication is possible.
We can handle everything from temporary scaffolding setup to exterior painting, roofing work, and exterior cover work completely in-house!
Since skylight installation involves dismantling or removing roofing materials, it can be done simultaneously with roof replacement or cover work, significantly reducing 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 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 roofing projects, such as those for factories!
We have qualified asbestos supervisors and asbestos surveyors on staff, so we can 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 use 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.
Subsidies and Grants That May Apply for Skylight Construction in Shinjuku-ku, Tokyo
In Shinjuku-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 couple households are eligible for new construction or purchase of energy-efficient homes, as well as energy-saving renovations of existing homes. In the case of new construction, the builder or purchaser is eligible, while 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 exceeding ZEH standards. For renovations, the work must improve the energy efficiency of the home through insulation upgrades or the introduction of energy-saving equipment. In both cases, it is required to contract with a registered business and complete the work within the specified period.
Maximum Subsidy Amount
For new construction, the maximum subsidy ranges from 400,000 yen to 1,600,000 yen per unit, depending on the performance classification of the home. For renovations, the maximum subsidy ranges from 400,000 yen to 600,000 yen per unit, 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 amount subsidy” is provided based on the content of the work and performance classification. Therefore, in effect, the government covers part of the construction cost.
For more details, please click 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 conducted by registered “window renovation contractors” with the government, and the granted subsidies are fully refunded to the homeowners through discounts on the construction costs.
Requirements
The eligible work includes window renovation aimed at improving insulation performance, such as installing interior windows, replacing exterior windows, and replacing glass 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 about 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 abundantly, it creates a sense of openness, making it feel pleasant.
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 suitable for energy conservation.
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 spaced houses, large windows can expose the interior of your home. However, with skylights, since they are 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 for installation, there is always some risk of leaks.
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 bothersome, 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 Procedure
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.
This is to ensure that no debris falls inside.
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 around the glass using butyl tape and other materials.
6. Restoration of Materials and Sealing
We will reattach the covers and fasteners that were holding the glass in place.
It is important to confirm that the fasteners are securely in place, as improper installation can lead to leaks.
We will also perform waterproofing treatment around the frame with sealing.
How to Choose a Skylight Contractor
There are many skylight contractors in Tokyo, and it can be confusing to decide which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, let’s check the following 5 points.
● They have extensive experience in skylight work.
● Confirm if they can also handle roofing work.
● Check for warranties and aftercare services.
● Obtain estimates from multiple contractors (at least 3).
● Confirm if they perform roof renovations in-house.
By checking the above 5 points, you will be able to choose a reliable contractor.
They have extensive experience in skylight work.
Skylight contractors often have websites that showcase their work experience.
Additionally, if they provide detailed explanations of repair work with photos, it can give you peace of mind when you decide to request repairs.
If you are concerned about whether the contractor you are about to hire will respond properly, choose one with rich repair experience.
It is also effective to refer to reviews on Google and review sites to look for skylight contractors!
If there are many negative reviews or no reviews at all, it may be wise to refrain from hiring them.
Kakeru Koumuten Co., Ltd. specializes in exterior work, so we receive many requests for skylight replacement work.
Confirm if they can handle roofing work.
Since skylights are installed on the roof, roofing work is often involved as well.
If the contractor lacks knowledge about roofs or cannot handle roofing work, it may lead to leaks after installation or result in high construction costs, leading to potential troubles.
Moreover, since skylight replacement or removal may require partial roof dismantling or restoration, performing roof overlay work or re-roofing simultaneously 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 aftercare services
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 are often confident in their work, which can serve as 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.
Furthermore, some contractors offer aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties andaftercare services.
Kakeru Koumuten Co., Ltd. sends out annual direct mail as part of our aftercare maintenance, allowing for yearly inspections.
We also provide free support for simple repairs such as partial sealing.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting skylight work, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, the repair costs can vary between contractors, as well as the warranties and aftercare services offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at the best possible price, obtaining estimates from multiple contractors is essential.
When comparing estimates, be sure to look at more than just the cost,
“Items in the estimate”
“Materials and quality such as glass”
“Confirmation of the process”
and make detailed comparisons! If the quality of auxiliary materials is low or if steps are skipped, costs can be reduced, so avoid making decisions based solely on price!
Check if the work is performed 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 subcontracts 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 who want to keep costs down are suggested to replace the skylight, which can be expensive, even though partial repairs would suffice.
Additionally, since they investigate and then request subcontractors, both time and costs can increase unnecessarily.
By having knowledge and experience and performing the work in-house, we can provide responsible construction while keeping costs down.
Moreover, with contractors that subcontract completely, one of the disadvantages is that response times during emergencies, such as post-construction troubles, can be inevitably slow.
