“Reasons why Kakeru Koumuten is chosen in Nakaguni (Oiso Town and Ninomiya Town)”
For customers living in Nakaguni (Oiso Town and Ninomiya Town) who are considering skylight replacements,
this information will surely be helpful, so please take a look!
To conclude, the most important thing to consider when planning skylight work is
“comparing estimates”!
Let’s obtain at least three estimates from skylight repair contractors covering Nakaguni (Oiso Town and Ninomiya Town)!
Reasons why Kakeru Koumuten is chosen for skylight work in Nakaguni (Oiso Town and Ninomiya Town)
One reason why you can trust us with skylight repairs in Nakaguni (Oiso Town and Ninomiya Town)
is that “Kakeru Koumuten is a roofing company within Kanagawa Prefecture,”
but also because of our “efforts in skylight replacement work that cannot be imitated by other companies”
, which have received high praise from many customers.
“cost, quality, and plans” 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 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, 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 installation.
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 handle everything from temporary scaffolding installation to exterior painting, roofing work, and exterior cover work completely in-house!
Since skylight installation involves dismantling or peeling off roofing materials, performing it simultaneously with roof replacement or cover work can significantly reduce costs!
3. Various Permits Obtained & 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
The skylight replacement work comes with a warranty!
Aftercare is available every year, and we will send out a 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 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 techniques and skills, we regularly provide technical training to ensure that all staff can respond effectively.
Subsidies and Grants That May Be Applicable for Skylight Construction in Nakaguni (Oiso Town and Ninomiya Town)
In Nakaguni (Oiso Town and Ninomiya Town), there are potential subsidies available when conducting skylight construction!
For details, please contact our company or the respective local government!
Kanagawa Prefecture Existing Housing Energy Efficiency Renovation Subsidy
Eligible Applicants
The eligible applicants for this subsidy are owners of existing homes in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible properties 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 with specified insulation performance such as windows, glass, and insulation materials designated by the national government for energy-efficient renovation work. Additionally, the home must ensure seismic performance, and a preliminary application must be submitted before starting the work, with construction commencing only after receiving a grant decision. Eligible construction work 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 for implementing eligible energy-efficient renovation work, 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 limit of 200,000 yen, the amount granted will be “up to the maximum limit.”

Child-Rearing Green Housing Support Project
Eligible Applicants
This program targets child-rearing households (households with children under 18) and young couples, focusing on the construction or purchase of new homes with high energy efficiency performance, or energy-efficient renovations of existing homes. In the case of new construction, the builder or purchaser is eligible, while for renovations, the contractor placing the order is eligible for the subsidy.
Requirements
For new homes, it is necessary to meet high energy efficiency standards set by the government, such as ZEH standards or higher. For renovations, the work must improve the home’s energy efficiency through insulation renovations 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.
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 between 400,000 yen and 600,000 yen, depending on the nature of the work. In both cases, 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 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.
For more details, please click here!
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 subsidy application process is carried out by registered “window renovation contractors” recognized by 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 equivalent to half of the construction costs. The actual subsidy amount is set at 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.

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 that can be opened and closed, ventilation improves.
Warm air rises, enhancing airflow.
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 the roof is opened 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 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 the case for all skylights. By choosing double-glazed glass or products with high sound insulation, the noise from rain can be reduced.

This concludes the work.
How to Choose a Skylight Contractor
In Nakaguni (Oiso Town and Ninomiya Town), there are many skylight contractors, and it can be confusing to choose the right one.
Therefore, when requesting skylight replacement work or leak repairs, it is important to check the following 5 points:
● 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 checking these 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 about to hire will respond properly, choose one with extensive repair experience.
It can also be effective to refer to reviews on Google and 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 Handle Roof Work
Since skylights are installed on roofs, roof work is often involved.
If the contractor lacks knowledge about roofs or cannot handle roof work, it may lead to issues such as leaks after installation 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 together 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-service 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, a company that offers a warranty is a sign of 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-service maintenance separate from warranties, so be sure to check if the contractor you are considering has warranties andafter-service maintenance.
Kakeru Koumuten Co., Ltd. sends out annual DM for after-service 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 companies)
When requesting skylight work, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, the repair costs may vary by contractor, as well as the warranties and after-service maintenance 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 rank 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 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 outsource completely, one of the disadvantages is that their response to post-construction issues or emergencies tends to be slow.
