“Reasons why Kakeru Koumuten is chosen in Hiratsuka City”
If you are considering a skylight replacement and live in Hiratsuka City,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing when considering skylight construction is
“multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors covering Hiratsuka City!
Reasons why Kakeru Koumuten is chosen for skylight construction in Hiratsuka City

One reason why we are entrusted with skylight repairs in Hiratsuka City is that
“being a roofing company in Kanagawa Prefecture” is one of the reasons,
“our unique approach to skylight replacement construction 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
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 performing 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 houses!
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, by separating and recycling the 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 installations.
Additionally, one representative will handle everything 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 the installation of temporary scaffolding to exterior painting, roofing work, and exterior cover work completely in-house!
Skylight installation involves dismantling or peeling off 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 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 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
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 all staff can respond effectively.
Possible Subsidies and Grants for Skylight Construction in Hiratsuka City
In Hiratsuka City, there are potential subsidies available when conducting skylight construction!
For details, please contact our company or your 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 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 work must target existing homes in the prefecture and utilize products with insulation performance specified by the national government, such as windows, glass, and insulation materials for energy-efficient renovations. Additionally, the home must ensure seismic performance, and a pre-application must be submitted before starting the construction, with construction commencing only after receiving a grant decision. Eligible renovation work includes insulation improvements 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-efficient 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 provided will be “up to the maximum limit.”

Child-Rearing Green Housing Support Project
Eligible Applicants
Households with children (households with children under 18) and young couples are the primary targets for new construction or purchase of homes with high energy efficiency performance, as well as for energy-efficient renovations of existing homes. In the case of 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 efficiency performance standards set by the government, such as exceeding ZEH standards. For renovations, the work must improve the home’s energy efficiency performance through insulation improvements 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.
Subsidy Upper Limit
For new constructions, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen depending on the performance classification of the housing. For renovations, the upper limit is 400,000 yen to 600,000 yen per unit, depending on the nature of the work. In either case, even if multiple projects are undertaken, the total subsidy cannot exceed this upper limit.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of construction costs; instead, it offers a predetermined “fixed subsidy” based on the type of work and performance classification. 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) that are undergoing insulation renovation work on windows and openings are eligible. The actual application process for the subsidy is carried out by registered “Window Renovation Contractors” recognized by the government, and the granted subsidy is fully refunded to the homeowners through discounts on the 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 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 capped at this upper limit.
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 classification, resulting in a total that is approximately 50% of the construction costs.

[Hiratsuka City] Hiratsuka City Existing Housing Insulation Renovation Subsidy
As part of its efforts to combat global warming, Hiratsuka City offers a program that subsidizes part of the costs associated with insulation renovations for existing homes that residents currently occupy or plan to occupy.

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 comes into the room, it creates a sense of openness, making it feel pleasant.
Energy Savings
This also contributes to high light transmission, allowing you to save on electricity costs due to the presence of natural light. As a result, the need to turn on electric lights during the day decreases, 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.
High Privacy
In areas where houses are closely packed together, installing large windows can make the interior visible. However, with skylights, since they are installed on the roof, 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, the risk can be minimized significantly.
Regular Maintenance Required
Skylights need to be maintained 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, which is a disadvantage. This sound can be particularly noticeable during heavy rain or storms.
However, this is not the case for all skylights. Choosing double-glazed glass or products with high sound insulation can reduce the noise from rain.

7. Cleaning
This will conclude the work.
How to Choose a Skylight Contractor
There are many skylight contractors in Hiratsuka City, and you may be unsure which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, it is important to check the following 5 points:
● Have extensive experience in skylight construction
● Confirm whether they can also handle roof work
● Check for warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether they perform roof renovations in-house
By checking the above 5 points, you will be able to choose a reliable contractor.
Have Extensive Experience in Skylight Construction
Skylight contractors often have websites showcasing their construction achievements.
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 extensive repair experience.
It is also effective to refer to reviews on Google and review sites to look for skylight contractors!
If there are many negative reviews or no reviews at all, it may be wise to refrain from making a request.
Kakeru Koumuten Co., Ltd. specializes in exterior work, so we receive many requests for skylight replacement work.
Confirm Whether 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 problems such as leaks after construction 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-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, 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 typically ranges from 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 services at no charge.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting skylight installation, be sure to obtain estimates from multiple contractors.
Even for the same repair or replacement work, the costs may differ 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, it is essential to obtain estimates from multiple contractors.
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 making judgments based solely on price!
Check if the company performs the work 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 repairs, 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 costly projects like skylight replacement, even though partial repairs would suffice.
Additionally, since the investigation is followed by a request to 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 completely, one of the drawbacks is that responses to emergencies or troubles after construction tend to be delayed.
