To conclude, the most important thing when considering skylight work is
“multiple estimates”!
Let’s obtain estimates from at least three companies that handle skylight repairs in Hachioji, Tokyo!

Reasons why Kakeru Koumuten is chosen for skylight work in Hachioji, Tokyo

Regarding why our company is entrusted with skylight repairs in Hachioji, Tokyo,
one reason is that “Kakeru Koumuten is a roofing company in Tokyo,”
but we also have “initiatives in skylight replacement work that cannot be imitated by other companies”
, which have 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 installations.
We have established 5 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 installations, allowing us to set up 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 approximately enough scaffolding materials for 50 single-family homes!

Material Storage 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, by separating and recycling waste materials, we can significantly cut waste disposal costs.

Showroom Dedicated to Exterior Renovations

In our showroom, you can not only have meetings, but 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 installations.
Additionally, one representative will handle everything from the estimate to project completion.
Since the representative does not change, whether it’s sales or 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 our in-house construction!

Since skylight installation involves dismantling or peeling off roofing materials, it can significantly reduce costs when done simultaneously with roof replacement or cover 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 Maintenance

The skylight replacement work comes with a warranty!
Aftercare maintenance 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 you!
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 by ourselves to improve our skills and conducting practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education so that each staff member can respond appropriately.

Possible Subsidies and Grants for Skylight Construction in Hachioji City, Tokyo

In Hachioji 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 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 who orders 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 ZEH level or higher. 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 carry out 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 home’s performance category, while for renovations, the maximum subsidy per unit ranges from 400,000 yen to 600,000 yen depending on the work content. In either case, even if multiple works are carried out, the total subsidy cannot exceed this maximum amount.

Subsidy Rate

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

For more details, please see 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 subsidy application process is carried out by registered “Window Renovation Contractors” with 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.

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 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 reduce the need to turn on lights during the day, making it suitable for energy conservation.

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, installing large windows may 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 rainwater 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. Choosing double-glazed glass or products with high sound insulation can reduce the noise from rain.

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 handle them carefully.

2. Preparation

We will prepare 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 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 held the glass in place.
It is important to ensure that the installation method matches the type of skylight being used to prevent leaks, so we will check that the fittings are secure.
We will perform waterproofing treatment around the frame with sealing.

How to Choose a Skylight Contractor

There are many skylight contractors in Hachioji City, and it can be confusing to decide which one to choose.

Therefore, when requesting skylight replacement work or leak repairs, it is important to check the following 5 points.

By confirming the above 5 points, you will be able to choose a reliable contractor.

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 adequately, choose one with extensive repair experience.

It can also be effective to refer to reviews on Google and review sites to look at 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, 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 may lead to issues such as leaks after installation or high construction costs.

Moreover, since skylight replacement or removal may require partial roof dismantling and restoration, performing roof overlay work or re-roofing simultaneously 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, 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, making it 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 after-sales services in addition to warranties, so be sure to check if the contractor you are considering has warranties andafter-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 free of charge.

Obtain estimates from multiple contractors (at least 3)

When requesting skylight installation, obtain estimates from multiple contractors.

Even for the same repair or replacement work, the costs and warranties or after-sales services can vary by contractor.

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 just 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 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 to replace the skylight, which can be expensive, even though partial repairs would suffice.

Additionally, since they need to 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 work, one of the drawbacks is that response times during emergencies, such as post-construction troubles, can be delayed.
