“Reasons why Kakeru Koumuten is chosen in Miura City”
For customers living in Miura City who are considering skylight replacements,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing when considering skylight construction is
“getting multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors
that cover the Miura City area!
Reasons why Kakeru Koumuten is chosen for skylight construction in Miura City

One reason why we are entrusted with skylight repairs in Miura City is that
“Kakeru Koumuten is a roofing company within Kanagawa Prefecture,”
but we also have “initiatives in skylight replacement construction 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 assemble scaffolding in-house.
By not outsourcing scaffolding work and using our own scaffolding team, we can reduce scaffolding construction costs and respond quickly in emergencies.
We have scaffolding materials for approximately 50 single-family homes!
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, 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 thermal insulation properties using a thermal 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 project.
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 completely in-house!
Since skylight installation involves dismantling or peeling off 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 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, 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 altitudes, we can utilize drones to assist!
During leak investigations, we can also conduct surveys using a thermal imaging camera, which helps identify 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 improve our skills, we create various roof models and conduct practical training.
Since different processing and techniques are required depending on the site, we regularly provide skill enhancement education to ensure that all staff can respond appropriately.
Subsidies and Grants That May Apply to Skylight Construction in Miura City
In Miura City, 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 Conservation Renovation Subsidy
Eligible Participants
The eligible participants for this subsidy are owners of existing homes located 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, the renovation must target existing homes in the prefecture and utilize products such as windows, glass, and insulation materials with specified insulation performance designated by the national government for energy conservation renovations. Additionally, the home must ensure seismic performance, and a prior application must be submitted before starting the construction, 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 conservation renovations are 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 “the maximum amount”.

Child-Rearing Green Housing Support Project
Eligible Participants
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 conservation performance, or energy conservation 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 conservation performance standards set by the government, such as ZEH standards or higher. For renovations, it is required to carry out work that improves the energy conservation performance of the home, such as insulation renovations or the introduction of energy-saving equipment. In both cases, it is necessary to contract with registered businesses and carry out the work within the specified period.
Subsidy Maximum Amount
For new constructions, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen depending on the housing performance category. For renovations, the maximum subsidy per unit is capped at 400,000 yen to 600,000 yen, depending on the scope of work. In either case, even if multiple projects are undertaken, 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, 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.
For more details, please click here!
Advanced Window Renovation Project
Eligible Participants
Homeowners of existing residences (single-family homes and multi-family dwellings) who are conducting 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 homeowners through discounts on construction costs.
Requirements
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 commence and be completed within the specified construction period.
Subsidy Maximum Amount
The maximum 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 capped at this maximum amount.
Subsidy Rate
The subsidy rate is approximately half of the construction costs. The actual subsidy amount is set as a fixed rate based on the type of window (interior, exterior, 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 abundantly, it creates a sense of openness, which I believe makes you feel good.
Energy Savings
This also contributes to high light transmission, as the presence of natural light allows you to save on electricity costs. Since you will reduce the need to turn on lights during the day, it is suitable for energy conservation.
Good Ventilation

By installing a skylight, you can open and close it, which improves ventilation.
Warm air rises, so airflow also improves.
High Privacy
In areas where houses are closely packed together, installing large windows can make the inside of your home visible. In such cases, skylights are installed on the roof, which helps 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 inevitably 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 surface can easily be transmitted indoors, which is a disadvantage. In particular, the sound may be quite noticeable during heavy rain or typhoons.
However, this is not something that is strongly felt with all skylights. By choosing double-glazed glass or products with high sound insulation, the noise from rain can be reduced.

7. Cleaning
This concludes the work.
How to Choose a Skylight Contractor
There are many skylight contractors in Miura City, 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:
● 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 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 showcasing their work history.
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 handle your request properly, choose one with ample repair experience.
It can also be 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 Roofing Work
Since skylights are installed on roofs, roofing work is often involved as well.
If the contractor lacks knowledge about roofs or cannot handle roofing work, there is a possibility of issues arising after installation, such as leaks or high construction costs.
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 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 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 after-sales services in addition to warranties, so be sure to check if the contractor you are considering has warranties andafter-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 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, the repair costs can vary by contractor, 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 of glass, etc.”
“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 construction. There may be cases where customers who want to keep costs down are suggested costly work like skylight replacement, even though partial repairs would suffice.
Additionally, since the contractor needs to investigate and then request a subcontractor, 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 work, one of the disadvantages is that response times during emergencies, such as post-construction troubles, can be inevitably slow.
