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 installations.
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 installations, allowing us to assemble scaffolding in-house.
By not outsourcing scaffolding work and using our own scaffolding team, we can cut costs on scaffolding construction 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 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 simulate exterior painting colors and verify heat insulation performance using our heat insulation testing equipment!

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 person in charge does not change, whether it’s sales or construction management, smooth communication is possible.

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

Since skylight installation involves dismantling or removing 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 national 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.

If you are unable to 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 by ourselves to improve our skills and conducting practical training.
Since different processing and techniques are required depending on the site, we regularly conduct skill enhancement training so that each staff member can respond effectively.

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, which I believe makes you feel good.

Energy Savings

This also contributes to the high light transmission, as the presence of natural light allows you to save on electricity costs. Since you will reduce the need to turn on lights during the day, it is suitable for energy conservation.

Good Ventilation

By installing a skylight, you can open and close it, which improves ventilation.
Warm air rises, so airflow is also enhanced.

High Privacy

In areas where houses are close together, installing large windows can make the inside of your home visible. In such cases, skylights are installed on the roof, which helps maintain 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 certainly 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 surface can easily be transmitted indoors, which is a disadvantage. In particular, the sound can be quite noticeable during heavy rain or typhoons.

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

Examples of Skylight Repair Work

Construction Location 　Tokyo Construction Details 　Skylight Glass Replacement Work New Materials Used Double Glazing Price Range 50,000 – 100,000 yen Construction Period 　1 Day Process Leading to Construction Due to a crack in the skylight glass, we received a request to replace the skylight glass in conjunction with the roof overlay work.

Skylight Glass Replacement Work Procedure

1. Remove the Surrounding Materials of the Skylight

First, we will remove the surrounding cover materials and securing materials of the skylight. These materials will be reused, so we will remove them carefully.

2. Protection

We will protect the area around the skylight indoors.
We will take measures to prevent debris from falling indoors.

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 ensure that it does not break, 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, etc.

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 skylight being used, as improper installation can 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 Akishima 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.

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

Have Extensive Experience in Skylight Work

Skylight contractors often have websites that 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 considering will respond properly, choose one with extensive repair experience.

It can be effective to refer to reviews on Google and review sites when looking for skylight installation contractors!
If there are many negative reviews or no reviews at all, it may be safer to refrain from making a request.

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

Check if they can handle roofing work

Since skylights are installed on the roof, roofing work is often involved as well.
If the contractor lacks knowledge about roofs or cannot handle roofing work, there is a possibility of issues arising after construction, such as leaks or high construction costs.

Additionally, replacing or removing a skylight may require partial dismantling of the roof and restoring it, so performing roof overlay work or re-roofing at the same time can significantly reduce costs!

Our company specializes in roofing work, so we will propose the optimal plan tailored to your needs for any roofing work associated with skylight installation.

Check for warranties and aftercare services

When choosing a skylight installation contractor, make sure to check for warranties.

If a leak occurs after the skylight installation, having a leak warranty from the contractor ensures that repairs can be done at no cost, providing peace of mind!
Moreover, 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 type of work, but typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.

Additionally, some contractors offer aftercare services separate from warranties, so be sure to check if the contractor you are considering has warranties and aftercare services.

At Kakeru Koumuten Co., Ltd., we send out annual direct mail for aftercare maintenance, allowing for yearly inspections.
For simple repairs like partial sealing, we provide services at no charge.

Obtain estimates from multiple contractors (at least three)

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

Even for the same repair or replacement work, the costs may 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 lowest 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 of glass, etc.”
“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!

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 wishes.

If a contractor completely outsources skylight repair work, they may lack knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary construction.
Customers who want to keep costs down may be proposed unnecessary work like skylight replacement, even when partial repairs would suffice.

Additionally, requesting subcontractors after an investigation incurs extra time and costs.
By having knowledge and experience and performing the work in-house, we can provide responsible construction while keeping costs down.

Moreover, contractors that fully outsource work may have delayed responses in emergencies such as post-construction troubles, which is another disadvantage.
