“Reasons why Kakeru Koumuten is chosen in Aoba-ku, Yokohama” and more
For customers living in Aoba-ku, Yokohama, who are considering skylight replacements,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing to consider when planning skylight construction is
“multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors covering Aoba-ku, Yokohama!
Reasons why Kakeru Koumuten is chosen for skylight construction in Aoba-ku, Yokohama
Regarding why we can be entrusted with skylight repairs in Aoba-ku, Yokohama,
one reason is that “Kakeru Koumuten is a roofing company in Tokyo,” but
“Our unique approach to skylight replacement work that cannot be imitated by other companies”
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 in-house.
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 approximately enough scaffolding materials for 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 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 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 project completion.
Since the same person is responsible for sales and construction management, smooth communication is possible.
We can fully handle everything from temporary scaffolding installation to exterior painting, roofing work, and exterior cover work in-house!
Since skylight installation involves dismantling or removing roofing materials, it can significantly reduce costs when done simultaneously with roof replacement or cover work!
3. Various permits obtained and skilled workers on staff
We have obtained permits for construction work and industrial waste collection and transportation!
We have qualified professionals such as national certified sheet metal workers and painting technicians, and we are confident in our construction techniques.
We are also capable of handling large-scale roofing projects for factories and other facilities!
We have qualified asbestos supervisors and asbestos surveyors on staff, allowing us to handle asbestos-containing roofing materials and conduct pre-investigations.
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 all staff can respond effectively.
Subsidies and Grants That May Apply to Skylight Construction in Kita-ku, Tokyo補助金、助成金
In Kita-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 homes with high energy-saving performance, or energy-saving renovations of existing homes. For 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-saving performance standards set by the government, such as ZEH standards. For renovations, the work must improve the energy-saving performance 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 carry out the work within the specified period.
Maximum Subsidy Amount
For new construction, the maximum subsidy amount ranges from 400,000 yen to 1,600,000 yen per unit, depending on the performance category of the home. For renovations, the maximum subsidy amount 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 amount cannot exceed this maximum limit.
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 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 application process for the subsidy is carried out by registered “window renovation contractors” with the government, and the granted subsidy is fully refunded to the homeowners through discounts on construction costs.
Requirements
The eligible renovations include installing interior windows, replacing exterior windows, and glass replacements 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 half of the construction cost. 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 cost.

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 is also related to high light transmission, as the presence of natural light allows for savings on electricity bills. Since the need to turn on lights during the day decreases, it is conducive to energy conservation.
Good Ventilation
By installing a skylight, it can be opened and closed, improving ventilation.
Warm air rises, enhancing airflow.
High Privacy
In areas with closely spaced houses, installing large windows can expose the interior of the home. In such cases, skylights, being installed on the roof, help maintain privacy.
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 water leakage.
However, with proper installation and regular maintenance, the risk can be minimized significantly.
Regular Maintenance Required
Skylights need maintenance approximately every 5 to 10 years to prevent leaks. While maintenance may seem bothersome, it is recommended to perform 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 protection 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 carefully install it to avoid breaking, just as we did during the 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 held the glass in place.
It is important to ensure that the installation method matches the type of skylight used, as improper installation can lead to leaks. We will check that the fasteners are securely in place.
Waterproofing treatment will be done 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, please check the following 5 points.
● They 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)
● Confirm if they perform roof renovations in-house
By confirming 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 where they showcase their work experience.
Additionally, if they provide detailed explanations of repair work with photos, it can give you peace of mind when you actually request repairs.
If you are concerned about whether the contractor you are about to hire will respond properly, 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 hiring them.
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 a 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, replacing or removing a skylight may require partial dismantling of the roof or restoration of the roof, so 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 a warranty demonstrate confidence in their work, which can serve as a criterion for selecting a contractor!
The warranty period varies by contractor and the nature of the work, but it is generally set between 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 support at no charge.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting skylight work, be sure to obtain estimates from multiple contractors.
Even for the same repair or replacement work, the repair costs may vary between contractors, as well as the warranties and after-sales services offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, obtaining estimates from multiple contractors is essential.
When comparing estimates, consider not only the cost but also
“Items in the estimate”
“Materials and quality such as glass”
“Confirmation of the process”
and make a detailed comparison! If the quality of auxiliary materials is low or if processes are skipped, costs can be reduced, so avoid judging solely based on price!
Confirm whether 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 outsources skylight repair work, they may lack knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary construction. There are cases where customers who want to keep costs down are suggested to replace the skylight, which can be expensive, even though a partial repair would suffice.
Additionally, since the contractor will investigate and then request a subcontractor, both time and costs will inevitably increase.
By having knowledge and experience and performing the work in-house, we can provide responsible construction while keeping costs down.
Moreover, with contractors that outsource work, one of the drawbacks is that response times during emergencies or post-construction issues can be significantly delayed.
