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

One reason why we are entrusted with skylight repairs in Hino City, Tokyo is that
Kakeru Koumuten Co., Ltd. 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.
“cost, quality, and plan” are our absolute strengths,
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 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, since we always have stock available, we canrespond 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 inquiry to project completion, everything is handled by Kakeru Koumuten in a consistent system, 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 same person will manage sales and construction, smooth communication is possible.
We can fully handle everything from temporary scaffolding setup to exterior painting, roofing work, and exterior cover work with complete in-house construction!
Skylight installation involves dismantling or removing roofing materials, so by carrying it out simultaneously with roof replacement or cover work, you can significantly reduce costs!
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 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 inspections 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 and techniques, we regularly provide skill enhancement education to ensure that each staff member can respond effectively.
Subsidies and Grants That May Be Applicable for Skylight Construction in Hino City, Tokyo
In Hino City, Tokyo, there are potential subsidies available when performing 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-efficient renovations of existing homes. For new construction, the builder or purchaser is eligible, while for renovations, the contractor is the eligible party.
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 construction, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen, depending on the performance category 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 this maximum amount.
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 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 subsidies are fully refunded to the homeowners through discounts on construction costs.
Requirements
The 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 received for the same residence will be up 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 enters the room abundantly, it creates a sense of openness, making you feel more comfortable.
Energy Savings

This is also related to the high light transmission, as having 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 where houses are closely built, 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, 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.

Skylight Glass Replacement Work – Construction Procedure
1. Remove the surrounding components 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 be careful to ensure that the glass does not break during installation, just as we were 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 were holding the glass in place.
It is important to ensure that the installation method matches the type of skylight being used, as improper installation could lead to leaks.
We will perform waterproofing treatment around the frame using sealing materials.
How to Choose a Skylight Contractor
There are many skylight contractors in Hino City, and you may be unsure which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, it is important to check the following 5 points.
● They have extensive experience in skylight work.
● Confirm if they can also handle roofing work.
● Check for warranties and aftercare services.
● Obtain estimates from multiple contractors (at least 3 companies).
● Confirm if they perform roof renovations in-house.
By checking 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 considering will handle your request properly, choose one with ample repair experience.
It can also be effective to look at reviews of skylight contractors on Google and review sites!
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 construction, so we receive many requests for skylight replacement work.
Confirm if they can also handle roofing work.
Since skylights are installed on roofs, roofing work is often involved.
If the contractor lacks knowledge about roofing or cannot handle roofing work, it could lead to leaks after installation or result in high construction costs, leading to potential troubles.
Additionally, since skylight replacement or removal may require partial dismantling of the roof 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 Warranty and After-Service Availability
When choosing a skylight contractor, let’s confirm the warranty availability.
If a leak occurs after the skylight installation, having a leak warranty from the contractor ensures that repairs can be done free of charge, providing peace of mind!
Additionally, companies that offer a warranty 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 after-service in addition to warranties, so be sure to check if the contractor you are considering has warranties and after-service.
At Kakeru Koumuten Co., Ltd., we send out annual DM for after-service, allowing for yearly inspections.
We also provide free support for simple repairs like partial sealing.
Obtain Estimates from Multiple Contractors (at least 3)
When requesting skylight work, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, costs and warranty or after-service offerings can vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, obtaining estimates from multiple contractors is essential.
When comparing estimates, consider not just the costs, but also
“Estimate Items”
“Materials and Quality of Glass”
“Confirmation of 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 judging solely based on price!
Confirm Whether 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 may be cases where customers who want to keep costs down are suggested to replace the skylight, even though partial repairs would suffice.
Additionally, since the contractor needs to investigate and then request a subcontractor, 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 their response to emergencies, such as post-construction issues, can be delayed.
