For customers living in Inagi City, Tokyo, who are considering skylight replacement,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing when considering skylight work is
“multiple estimates”!
Let’s get at least three estimates from skylight repair contractors covering Inagi City, Tokyo!
Reasons why Kakeru Koumuten is chosen for skylight work in Inagi City, Tokyo
Regarding why our company is entrusted with skylight repairs in Inagi City, Tokyo,
one reason is that “Kakeru Koumuten 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 plans” 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 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 conducting 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!
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 canpurchase materials at a lower cost!
Additionally, we always have stock available, allowing us torespond 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 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 manner, 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 installation to exterior painting, roofing work, and exterior covering work completely in-house!
Since skylight installation involves dismantling or removing roofing materials, doing it simultaneously with roof replacement or covering work can significantly reduce costs!
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, allowing us to handle asbestos-containing roofing materials and conduct pre-investigations.
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 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 repairs for sudden leaks from skylights!
6. Human Resource Development
We are creating various roof models to enhance our skills and conducting practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education to ensure all staff can respond effectively.

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 good.
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 electric lights 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 built, 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. After all, since it involves opening the roof for installation, there is a certain risk of leaks.
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. This can be particularly noticeable during heavy rain or storms.
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.

| Background to the Construction |

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 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 check that the fittings are securely in place.
Waterproofing treatment will be done around the frame with sealing.
How to Choose a Skylight Contractor
There are many skylight contractors in Inagi 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)
● Confirm if they perform roof renovations in-house
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 showcasing 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 about to hire will respond 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 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.
If the contractor lacks knowledge about roofs or cannot handle roofing work, it could lead to leaks after installation or high construction costs, resulting in potential troubles.
Furthermore, 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 aftercare services
When choosing a skylight 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 made at no cost, providing peace of mind!
Additionally, companies that offer warranty periods demonstrate confidence in their work, making it a key criterion in 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 leak warranties.
Furthermore, some contractors offer aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties and aftercare services.
Kakeru Koumuten Co., Ltd. sends out annual DM for 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 obtain estimates from multiple contractors.
Even for the same repair or replacement work, costs and warranties or aftercare services can vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred contractor at a lower price, it is essential to obtain estimates from several contractors.
When comparing estimates, consider not only the cost but also
“Items in the estimate”
“Materials and quality of glass”
“Confirmation of processes”
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 subcontracts 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 a partial repair 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 subcontract everything, one of the disadvantages is that their response to emergencies, such as post-construction troubles, can be inevitably slow.
