“Reasons why Kakeru Koumuten is chosen in Kanagawa Ward”
If you live in Kanagawa Ward and are considering a skylight replacement,
these resources will definitely be helpful, so please take a look!
To conclude, the most important thing to consider when planning skylight construction is
“multiple estimates”!
For skylight repair contractors covering Kanagawa Ward,
let’s obtain estimates from at least three companies!
Reasons why Kakeru Koumuten is chosen for skylight construction in Aoba-ku, Yokohama
One reason why we are entrusted with skylight repairs in Kanagawa Ward is that
“Being a roofing company in Yokohama” is one of the reasons, but
“Our unique approach to skylight replacement 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 installation.
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 installation, 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 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, 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, 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 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 same person is responsible for sales and construction management, smooth communication is possible.
We can handle everything from temporary scaffolding installation to exterior painting, roofing work, and exterior cover work completely in-house!
Since skylight installation involves dismantling or peeling off roofing materials, it can be done simultaneously with roof replacement or cover work, significantly reducing 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 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 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 altitudes, 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 repairs 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 techniques and skills, we regularly provide technical training to ensure that all staff can respond effectively.
Possible subsidies and grants for skylight construction in Aoba-ku, Yokohama
In Aoba-ku, Yokohama, there are potential subsidies available when carrying out skylight construction!
For details, please contact our company or your local government!
Kanagawa Prefecture Existing Housing Energy Efficiency Renovation Subsidy
Eligible Applicants
The eligible applicants for this subsidy are owners of existing homes located in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible homes 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-efficient renovation work. Additionally, the home must ensure seismic performance, and a pre-application must be submitted before starting the construction, with work commencing 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 home. This is the total subsidy provided when eligible energy-efficient renovation work is carried out, and no more than this amount can be received.
Subsidy Rate
The burden ratio for the subsidy 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 “the maximum amount”.

Child-Rearing Green Housing Support Project
Eligible Applicants
This program targets child-rearing households (households with children under 18) and young couples, focusing on new construction or purchase of homes with high energy efficiency performance, as well as energy-efficient renovations of existing homes. For new construction, the builder or buyer 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 efficiency standards set by the government, such as ZEH standards or higher. For renovations, the work must improve the home’s energy efficiency performance through insulation renovations or the introduction of energy-efficient equipment. In both cases, it is required to contract with a registered business and carry out the work within the specified period.
Subsidy Upper Limit
For new constructions, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen depending on the performance classification of the housing. For renovations, the upper limit is between 400,000 yen and 600,000 yen per unit, depending on the scope of work. In either case, even if multiple projects are undertaken, the total subsidy cannot exceed this upper limit.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of the construction costs; instead, it offers a predetermined “fixed subsidy” based on the type of work and performance classification. Therefore, in effect, the government covers part of the construction costs.
Advanced Window Renovation Project
Eligible Participants
Homeowners of existing residential properties (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 the homeowners through discounts on the construction costs.
Requirements
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 commence and be completed within the specified construction period.
Subsidy Upper Limit
The upper limit for subsidies is 2,000,000 yen per unit. Even if multiple windows are renovated, the total subsidy that can be received for the same residence is capped at this upper limit.
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, exterior, glass), size, and insulation performance classification, 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 also contributes to high light transmission, allowing you to save on electricity costs due to the presence of natural light. As a result, the need to turn on electric lights during the day decreases, 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 up the roof, there is 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 perform 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 transmit into the room. This can be 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, the noise from rain can be reduced.

How to Choose a Skylight Contractor
There are many skylight contractors in Yokohama, and you may be unsure which one to choose.
Therefore, when requesting skylight replacement work or leak repairs, let’s 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 conduct 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 showcasing their work history.
Additionally, if they provide detailed explanations of repair work with photos, it gives 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 when looking for skylight contractors!
If there are many negative reviews or no reviews at all, it may be wise to refrain from making a request.
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 the roof, 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 installation or high construction costs.
Moreover, since skylight replacement or removal may require partial dismantling of the roof and restoration, performing it together with roof overlay work or re-roofing 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, 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 done 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 leak warranties.
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.
At Kakeru Koumuten Co., Ltd., we send out annual DM for aftercare 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 installation, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, costs can vary between contractors, as can warranties and aftercare services.
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, it’s important to look at more than just the cost,
“Items in the estimate”
“Materials and quality of glass”
“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 contractor performs the work 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 construction.
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 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 of the disadvantages is that their response to emergencies, such as post-construction troubles, tends to be slow.
