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 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 construction, 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 Warehouse

 We store materials used for exterior renovations.
By ordering a large quantity of materials at once, you can purchase materials at a lower cost!
Additionally, we always have stock available, allowing for quick responses 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 these materials together, separating and recycling them can lead to significant cost reductions in waste disposal.

Exterior Renovation Dedicated Showroom

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 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’s 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 completely in-house!

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

3. Various permits obtained and skilled workers on staff

We have obtained permits for construction work and industrial waste collection and transportation!
We have nationally certified sheet metal workers and painting technicians, 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, 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 a 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 places, 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 to improve our skills and conducting practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education for all staff members.

Advantages and Disadvantages of Skylights

Advantages of Skylights

High Light Transmission

First, the advantage of skylights is their high light transmission.
When natural light floods into the room, it creates a sense of openness, making it feel pleasant.

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 energy-efficient.

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 packed together, installing 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, 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 is 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, rain noise can be reduced.

Background to the Construction

Due to cracks in the skylight glass, we received a request to replace the skylight glass in conjunction 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 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 held 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 with sealing.

How to Choose a Skylight Contractor

There are many skylight contractors in Ome 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 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 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 actually request repairs.

If you are concerned about whether the contractor you are about to hire will respond properly, choose one with extensive 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 requesting their services.

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 the roof, 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 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 after-sales maintenance

When choosing a skylight contractor, let’s confirm the presence of a warranty.

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, a company that offers a warranty is a sign of confidence in their work, making it a criterion for selecting a contractor!

The warranty period varies by contractor and the nature of the work, but it is generally set between 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 companies)

When requesting skylight work, let’s obtain estimates from multiple contractors.

Even for the same repair or replacement work, the repair costs may vary between contractors, as well as warranties and after-sales services.

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, be sure to look at not just the costs, 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 processes are skipped, costs can be reduced, so avoid making decisions based solely on price!

Check if the work is performed 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 costly projects like skylight replacement, 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 knowledge and experience and performing the work in-house, we can provide responsible construction while keeping costs down.

Moreover, with contractors that outsource completely, one disadvantage is that their response to post-construction issues or emergencies tends to be delayed.
