Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage areas to provide low-cost, high-quality exterior renovations such as skylight installations.
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 installations, allowing us to assemble 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 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 canprocure materials at a lower cost!
Additionally, we always have stock available, allowing us torespond 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 thermal insulation properties using a thermal insulation testing machine!

Skylight installation involves dismantling or removing roofing materials, so by performing it simultaneously with roof replacement or cover work, you can significantly reduce costs!

Subsidies and Grants That May Apply to Skylight Work in Isehara City補助金、助成金

In Isehara City, there are potential subsidies available when carrying out skylight work!
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 Work and Conditions

To receive the subsidy, the following requirements must be met. First, it is necessary to carry out energy efficiency renovation work using products such as windows, glass, and insulation materials that meet the insulation performance specified by the national government, targeting existing homes within the prefecture. 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 renovation work includes insulation upgrades 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 limit 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 eligible for the new construction or purchase of energy-efficient homes, or for energy-efficient renovations of existing homes. For new constructions, the builder or purchaser is eligible, while for renovations, the contractor placing the order is eligible for the subsidy.

Requirements

For new homes, they must meet high energy efficiency standards set by the national 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-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 house. For renovations, the upper limit is between 400,000 yen and 600,000 yen per unit, depending on the type of work. In both cases, even if multiple works are carried out, the total 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, a predetermined “fixed subsidy” is granted according to the type of work and performance category. Therefore, in effect, the government covers part of the construction costs.

Advanced Window Renovation Project

Eligible Participants

Owners of existing homes (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 the homeowners through discounts on construction costs.

Requirements

Eligible works include window renovations 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 subsidies is 2,000,000 yen per unit. Even if multiple windows are renovated, the total subsidy received for the same house will not exceed 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 according to 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.

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, 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 is also enhanced.

High Privacy

In areas where houses are closely packed together, installing large windows can make the inside of your home visible. 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. After all, since it involves opening up the roof, there is 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 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. In particular, the sound can 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.

How to Choose a Skylight Contractor

There are many skylight contractors in Isehara City, and you may be unsure which one to choose.

Therefore, when requesting skylight replacement work or leak repairs, please check the following 5 points:

By checking 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 as a reference when you request repairs.

If you are concerned about whether the contractor you are about to hire will respond adequately, choose one with extensive repair experience.

It is also 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 as well.
If the contractor lacks knowledge about roofs or cannot handle roof 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 at the same time 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, 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 at no cost, providing peace of mind!
Additionally, companies that offer warranty periods 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 provide 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.
We also provide free support for simple repairs such as partial sealing.

Obtain estimates from multiple contractors (at least 3)

When requesting skylight work, let’s obtain 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 aftercare services offered.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at the best possible price, obtaining estimates from multiple contractors is essential.

When comparing estimates, be sure to look at more than just the costs,
“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 performed 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 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 construction. There are cases where customers who want to keep costs down are suggested to replace the skylight, even though a partial repair would suffice.

Additionally, since the contractor needs to investigate and then request a subcontractor, both time and costs can increase unnecessarily.
By having the knowledge and experience to perform 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 their response to emergencies or troubles after construction tends to be delayed.
