“Why Kakeru Koumuten is chosen in Zama City”
For customers living in Zama City who are considering skylight replacements,
this information will definitely be helpful, so please take a look!
To conclude, the most important thing when considering skylight construction is
“multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors
serving Zama City!
Reasons why Kakeru Koumuten is chosen for skylight construction in Zama City
One reason we are entrusted with skylight repairs in Zama City is that
“being a roofing company in Kanagawa Prefecture” is one of the reasons,
but we also have “initiatives in skylight replacement work that cannot be imitated by other companies”
, which 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 installation.
We have established five bases for material storage and showrooms.
In-house Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for skylight installation, 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!
Storage of Materials in Our Large 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, since we always have stock available, we can 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 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 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 installation to exterior painting, roofing work, and exterior cover work with our complete in-house construction!
Skylight installation involves dismantling or removing roofing materials, so by carrying it out simultaneously with roofing replacement or cover work, you can significantly reduce costs!
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 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 places, we can respond using a drone!
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 measures for sudden leaks from skylights!
6. Human Resource Development
To enhance our skills, we create various roof models and conduct practical training.
Since different sites require various processing and techniques, we regularly provide skill enhancement education for all staff to ensure they can respond effectively.
Possible Subsidies and Grants for Skylight Construction in Zama City
In Zama City, there are potential subsidies available when performing skylight construction!
For details, please contact our company or your local government!
Kanagawa Prefecture Existing Housing Energy Conservation Renovation Subsidy
Eligible Participants
The eligible participants for this subsidy are owners of existing homes located in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible properties must be residences where the owner themselves lives, regardless of whether they are single-family homes or apartments.
Eligible Construction and Conditions
To receive the subsidy, the following requirements must be met. First, the renovation must target existing homes in the prefecture and use products with insulation performance specified by the national government, such as windows, glass, and insulation materials for energy-saving renovation work. Additionally, the residence must ensure seismic performance, and a pre-application must be submitted before starting the construction, with the condition that construction begins only after receiving a grant decision. Eligible construction includes insulation renovations for windows, floors, walls, and ceilings.
Subsidy Amount
The maximum amount for this subsidy is up to 200,000 yen per residence. This is the total subsidy provided when eligible energy-saving renovation work is carried out, and no more than this amount can be received.
Subsidy Rate
The subsidy burden ratio is **one-third (approximately 33%) of the eligible construction costs**. However, even if the calculated amount based on the subsidy rate exceeds the maximum of 200,000 yen, the amount granted will be limited to “up to the maximum amount.”

Child-Rearing Green Housing Support Project
Eligible Participants
Households with children (households with children under 18) and young couples are targeted for the construction or purchase of new homes with high energy-saving performance, or for energy-saving renovations of existing homes. For new constructions, the builder or purchaser is eligible, while for renovations, the contractor placing the order is eligible for the subsidy.
Requirements
For new homes, it is necessary to meet high energy-saving performance standards set by the government, such as ZEH standards or higher. For renovations, the condition is to carry out work that improves the energy-saving performance of the home, such as insulation renovations or the introduction of energy-saving equipment. In both cases, it is required to contract with a registered business and complete the work within the specified period.
Subsidy Maximum Amount
For new constructions, the maximum amount per unit is between 400,000 yen and 1,600,000 yen, depending on the performance category of the house. For renovations, the maximum amount per unit is between 400,000 yen and 600,000 yen, depending on the scope of work. In either case, even if multiple works are carried out, the subsidy cannot exceed this maximum amount.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of the construction costs; instead, a predetermined “fixed subsidy” is granted based on the scope of work and performance category. Therefore, in effect, the government covers part of the construction costs.

Advanced Window Renovation Project
Eligible Participants
Homeowners of existing houses (single-family homes and apartment buildings) who are conducting 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 homeowners through discounts on construction costs.
Requirements
Eligible renovations include the installation of interior windows, replacement of exterior windows, and glass replacements 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 construction must start and be completed within the specified period.
Subsidy Maximum Amount
The maximum subsidy amount is 2,000,000 yen per unit. Even if multiple windows are renovated, the total subsidy that can be received for the same house is limited 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 (interior window, exterior 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 comes into the room, it creates a sense of openness, making you feel more comfortable.
Energy Savings
This is also related to the high light transmission, as the presence of natural light allows you to save on electricity costs. Since you will need to turn on the lights less 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.
High Privacy
In areas where houses are closely packed together, large windows can make the interior visible. 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 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 structures 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, which is a disadvantage. This sound 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.

6. New Skylight Installation
By properly sealing against rain and performing regular maintenance, you can prevent leaks.
7. Cleaning
This concludes the work.
How to Choose a Skylight Contractor
There are many skylight contractors in Zama City, and you may be unsure which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, make sure to check the following 5 points:
● Have extensive experience in skylight work
● Confirm if they can also handle roof 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.
Have Extensive Experience in Skylight Work
Skylight contractors often have websites that showcase their construction achievements.
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 requesting their services.
Kakeru Koumuten Co., Ltd. specializes in exterior work, so we receive many requests for skylight replacement work.
Confirm if They Can Handle Roof Work
Since skylights are installed on roofs, roof work is often involved as well.
If the contractor lacks knowledge about roofs or cannot handle roof work, it may lead to issues such as leaks after construction or high construction costs.
Moreover, since skylight replacement or removal may require partial dismantling of the roof and restoration, performing roof overlay work or re-roofing together can significantly reduce costs!
Our company specializes in roofing work, so we can propose the optimal plan for roofing work associated with skylight installation tailored to our customers’ needs.
Check for warranties and aftercare services
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, companies that offer warranty periods are often confident in their work, making this a key 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 aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties andaftercare services.
Kakeru Koumuten Co., Ltd. sends 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 3)
When requesting skylight work, be sure to obtain estimates from multiple contractors.
Even for the same repair or replacement work, costs and the availability of warranties and aftercare services can vary by contractor.
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, be sure to look at more than just the cost,
“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!
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 a contractor 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 when partial repairs would suffice.
Additionally, since the contractor needs to investigate and then request a subcontractor, it 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, with contractors that outsource work, one of the disadvantages is that their response to emergencies, such as post-construction troubles, tends to be delayed.
