For customers living in Aoba-ku, Yokohama who are considering skylight replacement,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing when considering skylight work is
“getting 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 work in Aoba-ku, Yokohama
One reason why we are entrusted with skylight repairs in Aoba-ku, Yokohama is
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”
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 conducting scaffolding work with our own scaffolding team instead of outsourcing, 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, separating and recycling waste materials can significantly cut waste disposal costs.
Exterior Renovation Dedicated Showroom
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 assist you from the estimate to the completion of the work.
Since the same person handles everything, including sales and construction management, smooth communication is possible.
We can handle everything from temporary scaffolding installation to exterior painting, roofing work, and exterior cover work completely in-house!
Skylight installation involves dismantling or removing roofing materials, so by performing it simultaneously with roof replacement or cover work, you can significantly reduce costs!
3. Various permits obtained and skilled workers on staff
We have obtained permits for construction work and 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, so we can handle asbestos-containing roofing materials and conduct preliminary surveys.
4. Warranty and Aftercare
Roof window 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.
If you are unable to access the roof at high altitudes, we can utilize drones to assist!
During leak investigations, we can also conduct inspections using a thermal imaging camera, which helps in identifying the cause of leaks!
We will respond according to your wishes.
We also accept emergency repairs for sudden leaks from skylights!
6. Human Resource Development
To enhance our skills, we create various roof models and conduct practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education for all staff members.
Subsidies and Grants That May Be Applicable for Skylight Construction in Aoba-ku, Yokohama
In Aoba-ku, Yokohama, 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-saving renovations of existing homes. For new construction, the builder or purchaser is eligible, while for renovations, the contractor ordering 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, it is required to carry out work that improves the energy efficiency of the home, such as insulation upgrades or the introduction of energy-saving equipment. In both cases, it is necessary to contract with a registered business and complete 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 program 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 conducted by registered “window renovation contractors” recognized by the government, and the granted subsidies are 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 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, which I believe makes you feel good.
Energy Savings
This also contributes to high light transmission, allowing you to save on electricity costs due to the presence of natural light. You will reduce the need to turn on electric lights during the day, making it suitable for energy conservation.
Good Ventilation
By installing a skylight, you can open and close it, which improves ventilation.
Warm air rises, enhancing airflow as well.
High Privacy
In areas where houses are closely built, installing large windows can expose the interior of your home. In such cases, skylights are installed on the roof, ensuring 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 the roof for installation, there is a certain risk of leaks.
However, with proper installation and regular maintenance, the current skylights can minimize this risk significantly.
Regular Maintenance Required
Skylights need maintenance 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 surface can easily transmit into the room. 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.
We will take measures 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 install it without breaking the glass, just as we were when removing it.
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 being used, as improper installation could lead to leaks. We will check that the fittings are securely fastened.
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, be sure to 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 companies).
● Confirm if they perform roof renovations in-house.
By checking these 5 points, you will be able to choose a reliable contractor.
They have extensive experience in skylight work.
Skylight contractors often have websites showcasing 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 request repairs.
If you are concerned about whether the contractor you are about to hire will respond properly, choose one with ample repair experience.
It can also be effective to look at reviews of skylight contractors on Google or 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 also handle roofing work.
Since skylights are installed on roofs, roofing work is often involved.
If the contractor lacks knowledge about roofs or cannot handle roofing work, it may lead to leaks after installation or high construction costs, resulting in potential troubles.
Furthermore, since skylight replacement or removal may require partial dismantling of the roof 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, make sure to check for warranties.
If a leak occurs after the skylight installation, having a leak warranty from the contractor ensures that repairs can be done free of charge, 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!
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 aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties and aftercare services.
Kakeru Koumuten Co., Ltd. sends out annual DM for aftercare maintenance, allowing for yearly inspections.
For simple repairs like partial sealing, we provide support free of charge.
Obtain estimates from multiple contractors (at least 3)
When requesting skylight installation, be sure to get estimates from multiple contractors.
Even for the same repair or replacement work, repair costs may differ between contractors, as well as warranties and aftercare services.
Additionally, obtaining multiple estimates makes price negotiations easier.
To request your desired repair contractor at the best possible price, it is essential to obtain estimates from multiple contractors.
When comparing estimates, consider not just the costs, 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 the auxiliary materials is low or if processes are skipped, costs can be reduced, so avoid making decisions based solely on price!
Check if the work is done in-house
There are various construction methods for skylight repair plans, including full replacement, roof overlay (cover method), and partial repairs!
The content of the plan will vary depending on the actual state of deterioration and the customer’s wishes.
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 who want to keep costs down are suggested to replace the skylight, which incurs higher costs, even though a partial repair would suffice.
Additionally, since the contractor will investigate and then request a subcontractor, it will take extra time and cost.
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, such as post-construction troubles, can be delayed.
