Reasons why Kakeru Koumuten is chosen for skylight work in Nishitama-gun, Tokyo

one reason is that “Kakeru Koumuten is a roofing company in Tokyo,” but
“Our unique approach to skylight replacement work that cannot be imitated by other companies”
has received high praise from many customers.

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 centered around Yokohama City 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 assemble scaffolding in-house.
By conducting 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 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, 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 thermal insulation properties using a thermal 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 be sales or construction management, smooth communication is possible.

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

Since skylight installation involves dismantling or peeling off roofing materials, it can be done simultaneously with roof replacement or cover work, significantly reducing costs!

3. Various Permits Obtained & 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 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 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 techniques and skills, we regularly provide technical training to ensure that all staff can respond effectively.

Subsidies and Grants That May Apply to Skylight Construction in Nishitama-gun, Tokyo

In Nishitama-gun, Tokyo, there are potential subsidies available when carrying out 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, as well as energy-efficient renovations of existing homes. In the case of new construction, the builder or purchaser is eligible, while for renovations, the contractor ordering the work is eligible for the subsidy.

Requirements

For new homes, it is necessary to meet high energy efficiency standards set by the government, such as exceeding ZEH levels. For renovations, the work must improve the energy efficiency of the home through insulation upgrades 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.

Maximum Subsidy Amount

For new construction, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen, depending on the performance classification of the home. For renovations, the maximum subsidy per unit ranges from 400,000 yen to 600,000 yen, 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 classification. 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 carrying out insulation renovation work on windows and openings are eligible. The actual application process for the subsidy is conducted by registered “window renovation contractors” recognized by the government, and the granted subsidy is 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 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 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 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 enters the room abundantly, it creates a sense of openness, making you feel good.

Energy Savings

This is also related to high light transmission, as the presence of natural light allows you to save on electricity bills. 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 as well.

High Privacy

In areas with closely spaced houses, installing large windows can expose the interior of your home. In such cases, skylights are installed on the roof, thus maintaining your privacy.

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 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 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

Cracks had developed in the skylight glass, leading to a request for replacement in conjunction with the roof overlay work.

Skylight Glass Replacement Work – Construction Procedure

1. Remove the components around 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 carefully install it to prevent any breakage.

5. Waterproofing Treatment

When replacing the skylight glass, it may be necessary to perform waterproofing treatment.
We will use butyl tape and other materials for waterproofing around the glass.

6. Restoration of Materials and Sealing

We will reattach the covers and fasteners that held the glass in place.
If the installation method does not match the type of skylight being used, it could lead to leaks, so we will ensure 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 Nishitama-gun, 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 where they showcase their work experience.

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 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 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 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 construction or high costs, resulting in potential troubles.

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 made 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 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.
We provide free support for simple repairs such as partial sealing.

Obtain estimates from multiple contractors (at least 3)

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

Even for the same repair or replacement work, the costs can vary between contractors, 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, 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 steps 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 construction. 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 the knowledge and experience to perform 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 response times during emergencies, such as post-construction troubles, can be inevitably slow.
