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 construction.
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 construction, allowing us to assemble scaffolding in-house.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can reduce scaffolding construction 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 even 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 our complete in-house construction.

From inquiries to project completion, everything is handled in a consistent manner by Kakeru Koumuten, 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 sales and construction management, smooth communication is possible.

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

Since skylight installation involves dismantling or removing roofing materials, it can be significantly more cost-effective when done simultaneously with roof replacement or cover work!

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 measures for sudden leaks from skylights!

6. Human Resource Development

We are creating various roof models by ourselves to enhance our skills and conducting practical training.
Since different processing and techniques are required depending on the site, we regularly provide skill enhancement education to ensure that each staff member can respond effectively.

Subsidies and Grants That May Apply to Skylight Construction in Chofu City, Tokyo

In Chofu City, 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 Applicants

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 the subsidy.

Requirements

For new homes, it is necessary to meet high energy efficiency 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 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 between 400,000 yen and 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 amount cannot exceed this limit.

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 Applicants

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 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 construction costs.

Requirements

Eligible work includes window renovation aimed at improving insulation performance, such as installing interior windows, replacing exterior windows, or replacing 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.

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 is limited to this maximum amount.

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 (inner window, outer window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction costs.

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 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 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, 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 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 the case for all skylights. By choosing double-glazed glass or products with high sound insulation, the noise from rain can be reduced.

Background to the Construction

Cracks had developed in the skylight glass, so 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. We will carefully install it to avoid breaking, just as we did during the removal.

5. Waterproofing Treatment

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

6. Restoration of Materials and Sealing

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

How to Choose a Skylight Contractor

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

Therefore, when requesting skylight replacement work or leak repairs, let’s 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 that showcase 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 well, choose one with rich repair experience.

It can also be 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 hiring them.

Kakeru Koumuten Co., Ltd. specializes in exterior work, and we receive many requests for skylight replacement work.

Confirm if they can also handle roofing work

Since skylights are installed on roofs, roofing work often comes into play.
If the contractor lacks knowledge about roofs or cannot handle roofing work, it may lead to leaks after installation or high construction 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 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 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 are often confident 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 as aftercare maintenance, allowing for yearly inspections.
We also provide free assistance for simple repairs like partial sealing.

Obtain estimates from multiple contractors (at least 3)

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

Even for the same repair or replacement work, costs and the availability of warranties or aftercare services can vary between contractors.

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 just the costs, but also
“Items in the estimate”
“Materials and quality of 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 work.
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 will 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, contractors that outsource work may have delayed responses during emergencies or issues after construction, which is one of the drawbacks.
