“About the costs of skylight repairs and replacements”
“Reasons why Kakeru Koumuten is chosen in Aoba-ku”
These will definitely be helpful for customers living in Aoba-ku who are considering skylight replacements,
so please take a look!
To conclude, the most important thing to consider when planning skylight work is
“multiple estimates”!
Let’s obtain estimates from at least three skylight repair contractors that cover Aoba-ku!
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 is that
“Being a roofing company in Yokohama” is one of the reasons, 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 plan” are our absolute strengths,
1. Equipment Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage to provide low-cost, high-quality exterior renovations such as skylight installations.
We have established 5 bases centered around Yokohama City 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 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 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 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, 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 heat insulation testing equipment!
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 person in charge does not change, whether it’s sales or construction management, smooth communication is possible.
We can fully handle everything from temporary scaffolding setup to exterior painting, roofing work, and exterior cover work in-house!
Since skylight installation involves dismantling or removing roofing materials, it can be significantly more cost-effective to carry out this work simultaneously with roof replacement or cover work!
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 technicians, 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 annual notification DM.
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 altitudes, 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 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 to ensure all staff can respond effectively.
Possible subsidies and grants 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!
Kanagawa Prefecture Existing Housing Energy Efficiency Renovation Subsidy
Eligible Persons
The eligible persons for this subsidy are owners of existing homes in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible homes must be residences where the owner themselves lives, regardless of whether they are single-family homes or apartments.
Eligible Construction and Conditions
To receive the subsidy, the following requirements must be met. First, it is necessary to target existing homes within the prefecture and carry out energy efficiency renovation work using products with insulation performance specified by the national government, such as windows, glass, and insulation materials. Additionally, the home must ensure seismic performance, and a prior application must be submitted before starting the work, with construction commencing only after receiving a grant decision. Eligible construction includes insulation renovations for windows, floors, walls, and ceilings.
Subsidy Amount
The maximum amount for this subsidy is up to 200,000 yen per residence. This is the total subsidy provided when eligible energy efficiency renovation work is carried out, and no more than this amount can be received.
Subsidy Rate
The burden ratio for the subsidy is **one-third (approximately 33%) of the eligible construction costs**. However, even if the calculated amount based on the subsidy rate exceeds the maximum of 200,000 yen, the amount granted will be limited to “up to the maximum amount.”
For more details, please see here!
Child-Rearing Green Housing Support Project
Eligible Persons
This program targets child-rearing households (households with children under 18) and young couples, focusing on new construction or purchase of homes with high energy efficiency performance, or energy-efficient renovations of existing homes. For new constructions, the builder or purchaser is eligible, while for renovations, the contractor is the eligible party.
Requirements
For new homes, it is necessary to meet high energy efficiency performance standards set by the government, such as exceeding ZEH levels. For renovations, it is required to carry out work that improves the energy efficiency of the home, such as insulation renovations or the introduction of energy-efficient equipment. In both cases, it is necessary to contract with registered businesses and carry out the work within the specified period.
Subsidy Upper Limit
For new constructions, the maximum subsidy per unit is between 400,000 yen and 1,600,000 yen, depending on the performance category of the housing. For renovations, the upper limit is between 400,000 yen and 600,000 yen per unit, depending on the scope of work. In both cases, even if multiple works are carried out, the subsidy cannot exceed this upper limit.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of the construction costs; instead, it offers a predetermined “fixed subsidy” based on the type of work and performance category. Therefore, in effect, the government covers part of the construction costs.
Please see here for more details!
Advanced Window Renovation Project
Eligible Participants
Homeowners of existing residences (single-family homes and apartment buildings) who are conducting 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 the construction costs.
Requirements
Eligible works include window renovation projects aimed at improving insulation performance, such as installing interior windows, replacing exterior windows, and exchanging 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.
Subsidy Upper Limit
The upper limit for the subsidy is 2,000,000 yen per unit. Even if multiple windows are renovated, the total subsidy that can be received for the same residence is limited to this upper 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 (interior window, exterior window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction costs.

Customer Testimonials
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 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. 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, improving ventilation.
Warm air rises, enhancing airflow as well.
High Privacy
In areas where houses are closely packed together, 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, there is always some risk of water leakage.
However, with proper installation and regular maintenance of modern skylights, this 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 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, which is a disadvantage. This sound can be particularly noticeable during heavy rain or storms.
However, this is not the case for all skylights. By choosing double-glazed glass or products with high sound insulation, the noise from rain can be reduced.

Skylight Glass Replacement Work – Construction Procedure
1. Remove the materials around 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. Preparation
We will prepare 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 held the glass in place.
It is important to ensure that the installation method matches the type of skylight being used, as improper installation can lead to leaks. We will check that the hardware is securely fastened.
We will perform waterproofing treatment around the frame with sealing.
How to Choose a Skylight Contractor
There are many skylight contractors in Yokohama, and it can be confusing to decide which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, it is important 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).
● 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 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 decide to request repairs.
If you are concerned about whether the contractor you are considering will respond adequately, choose one with rich repair experience.
It is also effective to refer to reviews on Google or review sites when looking for skylight contractors!
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 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.
Moreover, since skylight replacement or removal may require partial dismantling of the roof and 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 for roofing work associated with skylight installation tailored to our customers’ needs.
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 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!
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 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 for aftercare maintenance, allowing for yearly inspections.
For simple repairs such as partial sealing, we provide services free of charge.
Obtain estimates from multiple contractors (at least 3)
When requesting skylight installation, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, the costs and warranties or aftercare services can vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired 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 of 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 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 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 who want to keep costs down are suggested to replace the skylight, which incurs higher costs, 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 outsource completely, one of the disadvantages is that response times during emergencies, such as post-construction issues, can be delayed.
