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 set up scaffolding in-house.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can reduce scaffolding costs 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 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 complete in-house construction.

From inquiry 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 the sales representative or the construction management representative, smooth communication is possible.

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

Since skylight installation involves dismantling or removing roofing materials, it can be significantly cost-effective to carry it out simultaneously with roofing replacement or covering 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 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

We are creating various roof models to improve our skills and conducting practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education to ensure all staff can respond effectively.

Subsidies and Grants That May Apply for Skylight Construction in Chuo-ku, Tokyo

In Chuo-ku, Tokyo, there are potential subsidies available when conducting skylight construction!
For details, please contact our company or your local government!

Child-Rearing Green Housing Support Project

Eligible Participants

Households with children (households with children under 18) and young couples are eligible for new construction or purchase of energy-efficient homes, or energy-saving renovations of existing homes. For new construction, the builder or purchaser is eligible, while for renovations, the contractor ordering the work is eligible for subsidies.

Requirements

For new homes, it is necessary to meet high energy efficiency standards set by the government, such as 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-saving equipment. In both cases, it is necessary to contract with a registered business and complete the work within the specified period.

Maximum Subsidy Amount

For new homes, the maximum subsidy amount ranges from 400,000 yen to 1,600,000 yen per unit, depending on the performance category of the home. For renovations, the maximum subsidy amount is 400,000 yen to 600,000 yen per unit, depending on the content of the work. In either case, even if multiple works are carried out, the total subsidy cannot exceed these maximum amounts.

Subsidy Rate

This project does not provide a subsidy based on a certain percentage of the construction cost; instead, a predetermined “fixed subsidy” is provided based on the content of the work and performance category. Therefore, in effect, the government covers part of the construction cost.

For more details, please click here!

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” with the government, and the granted subsidies are fully refunded to the homeowners through discounts on the construction costs.

Requirements

Eligible renovations include installing interior windows, replacing 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 start and be completed within the specified construction period.

Maximum Subsidy Amount

The maximum subsidy is 2 million yen per household. Even if multiple windows are renovated, the total subsidy that can be received for the same residence will be up to this maximum amount.

Subsidy Rate

The subsidy rate is approximately half of the construction cost. The actual subsidy amount is set at a fixed rate based on the type of window (inner window, outer window, glass), size, and insulation performance category, resulting in a total that is about 50% of the construction cost.

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 comes into the room, it creates a sense of openness, making it feel pleasant.

Energy Savings

This is related to their high light transmission, as natural light allows you to save on electricity costs. Since you will use less electric lighting during the day, it is conducive to energy savings.

Good Ventilation

By installing a skylight, you can open and close it, which improves ventilation.
Warm air rises, enhancing airflow.

High Privacy

In areas with closely spaced houses, 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. After all, since it involves opening the roof, there is 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 troublesome, 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 noise can be particularly noticeable during heavy rain or storms.

However, this is not strongly felt with all skylights. By choosing double-glazed glass or products with high sound insulation, the sound of rain can be reduced.

Background to the Construction

Due to cracks in the skylight glass, we received a request to replace the skylight glass along with the roof overlay work.

Skylight Glass Replacement Work – Construction Procedure

1. Remove the surrounding materials of the skylight

First, we will remove the cover materials and securing materials around the skylight. These materials will be reused, so we will take them off carefully.

2. Protection

We will protect the area around the skylight indoors.
This is to ensure that no debris falls inside.

3. Removal of Existing Glass

Next, after removing the cover materials, we will take out the existing glass.

4. Installation of New Glass

Once the existing glass is removed, we will install the new glass. Just like during removal, we will be careful to avoid breaking the glass during installation.

5. Waterproofing Treatment

When replacing the glass of the skylight, waterproofing treatment may be necessary.
We will perform waterproofing around the glass using butyl tape and other materials.

6. Restoration of Materials & Sealing

We will reattach the covers and fasteners that were holding the glass in place.
It is important to ensure that the method used matches the type of skylight being installed, as improper installation could lead to leaks. We will check that the fittings are securely fastened.
We will perform waterproofing treatment around the frame with sealing.

How to Choose a Skylight Contractor

There are many skylight contractors in Tokyo, 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 confirming the above 5 points, you will be able to choose a reliable contractor.

They have extensive experience in skylight work

Skylight contractors often have websites showcasing their work experience.

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 adequately, choose one with rich 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 might be wise to refrain from hiring them.

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, it could lead to leaks after installation or result in high construction costs, leading to potential troubles.

Furthermore, 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 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 is generally set between 1 to 10 years.
Emergency measures or partial repairs often do not come with a leak warranty.

Moreover, some contractors offer aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties andaftercare services.

Kakeru Koumuten Co., Ltd. sends out annual DM for aftercare maintenance, allowing for yearly inspections.
For simple repairs like partial sealing, we provide support at no charge.

Obtain estimates from multiple contractors (at least 3)

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

Even for the same repair or replacement work, the repair costs, warranties, and aftercare services may vary by contractor.

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.”
“Verification 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 costly projects like skylight replacement, even though partial repairs would suffice.

Additionally, since they 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 their response to emergencies or issues after construction tends to be slow.
