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 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 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, 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 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 assist you from the estimate to the completion of the project.
Since the same person handles everything, including sales and construction management, smooth communication is possible.

We can fully handle everything from temporary scaffolding installation to exterior painting, roofing work, and exterior cover work with complete in-house construction!

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

3. Various Permits Obtained & Skilled Workers Available

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 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 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.

Possible Subsidies and Grants for Skylight Construction in Aotsugi City

In Aotsugi 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 Efficiency Renovation Subsidy

Eligible Applicants

The eligible applicants 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, it is necessary to target existing homes in the prefecture and carry out energy-efficient renovation work using products such as windows or glass with specified insulation performance and insulation materials designated by the national government. Additionally, the home must ensure seismic performance, and a pre-application must be submitted before the start of 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-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 amount.”

For more details, please see here!

Child-Rearing Green Housing Support Project

Eligible Applicants

This program targets child-rearing households (households with children under 18) and young couple households, focusing on those who are building or purchasing new homes with high energy efficiency performance, or renovating existing homes for energy efficiency. In the case of new construction, the builder or purchaser is eligible, while in the case of 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, 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 a registered business 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 classification of the house. For renovations, the maximum subsidy per unit is between 400,000 yen and 600,000 yen, 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 the 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.

Advanced Window Renovation Project

Eligible Participants

Homeowners of existing residential buildings (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 renovations include the installation of interior windows, replacement of exterior windows, and glass replacements 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 subsidies 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.

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 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. As a result, you will use less electricity during the day, making it suitable for energy savings.

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 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 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. 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.

How to Choose a Skylight Contractor

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

Therefore, when requesting skylight replacement work or leak repairs, make sure to check the following 5 points.

By checking the above 5 points, you will be able to choose a trustworthy contractor.

Have Extensive Experience in Skylight Work

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 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 Whether They Can Handle Roof Work

Since skylights are installed on roofs, roof work often comes into play.
If the contractor lacks knowledge about roofs or cannot handle roof work, there is a possibility of issues arising after construction, 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 after-sales maintenance

When choosing a skylight contractor, make sure to check for 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, companies that offer a warranty demonstrate confidence in their work, making it a key 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 and after-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)

When requesting skylight installation, make sure to obtain estimates from multiple contractors.

Even for the same repair or replacement work, the costs may vary 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 contractor at a lower price, it is essential to obtain estimates from multiple companies.

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 detailed comparisons! If the quality of auxiliary materials is low or if steps are skipped, costs can be reduced, so avoid making decisions based solely on price!

Check if the contractor 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 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 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 contractor will need to investigate and then request a subcontractor, both time and costs will increase.
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 drawbacks is that response times during emergencies, such as post-construction troubles, can be significantly delayed.
