“Reasons why Kakeru Koumuten is chosen in Aoba-ku, Yokohama”
For customers living in Aoba-ku, Yokohama, 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
“getting multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors covering Aoba-ku, Yokohama!
Reasons why Kakeru Koumuten is chosen for skylight construction in Aoba-ku, Yokohama

The reasons why you can trust us with skylight repairs in Aoba-ku, Yokohama,
include the fact that “Kakeru Koumuten is a roofing company in Kanagawa Prefecture,”
but also“our unique approach to skylight replacement work that cannot be imitated by other companies”
, which 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 installations.
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 installations, allowing us to set up scaffolding in-house.
By performing scaffolding work with our own scaffolding team instead of outsourcing, we can reduce scaffolding costs and respond quickly in emergencies.
We have enough 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 canprocure 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 thermal insulation properties using a thermal 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 installations.
Additionally, one representative will handle everything from the estimate to the completion of the project.
Since the same person will be in charge, 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 covering work with complete in-house construction!
Since skylight installation involves dismantling or removing roofing materials, it can be significantly more cost-effective when done simultaneously with roof replacement or covering 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 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 every 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 rain 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
To improve our skills, we create various roof models and conduct practical training.
Since different processing and techniques are required depending on the site, we regularly provide skill enhancement education to ensure all staff can respond effectively.
Subsidies and Grants That May Be Applicable for Skylight Construction in Odawara City
In Odawara 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 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, it is necessary to conduct energy efficiency renovation work using products such as windows or glass with specified insulation performance and insulation materials designated by the national government, targeting existing homes within the prefecture. Additionally, the home must ensure seismic performance, and a pre-application must be submitted before starting the work, 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 efficiency renovation work is carried out, and no more than this amount can be received.
Subsidy Rate
The burden ratio of 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 limit of 200,000 yen, the amount provided will be “up to the maximum limit.”
For more details, please see here!
Child-Rearing Green Housing Support Project
Eligible Applicants
Households with children (households with children under 18) and young couples are eligible for the construction or purchase of new homes with high energy efficiency performance, or for energy efficiency renovations of existing homes. In the case of new construction, the builder or purchaser is eligible, while for renovations, the contractor is the eligible party.
Requirements
For new homes, it is necessary to meet high energy efficiency performance standards set by the government, such as ZEH standards or higher. For renovations, it is required to carry out work that improves the energy efficiency performance of the home, such as insulation renovations or the introduction of energy-efficient equipment. In both cases, it is necessary 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 is between 400,000 yen and 1,600,000 yen, depending on the performance category of the house. 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 works are carried out, the subsidy cannot exceed this upper limit.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of the construction cost; instead, a predetermined “fixed subsidy” is granted based on the type of work and performance category. Therefore, in effect, the government covers part of the construction cost.
For more details, please check here!
Advanced Window Renovation Program
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 subsidy is 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 house is limited to 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 window, exterior window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction costs.

Customer Testimonials
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, you will use less electricity 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 as well.
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. 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 interiors 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, which is a disadvantage. This sound 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.

Skylight Replacement Work – Construction Procedure

6. New Skylight Installation
By properly performing rainwater management and conducting regular maintenance, you can prevent leaks.
7. Cleaning
This concludes the work.
How to Choose a Skylight Contractor
There are many skylight contractors in Odawara 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:
● Have extensive experience in skylight construction
● Confirm if they can also handle roofing 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 confirming the above 5 points, you will be able to choose a reliable contractor.
Have Extensive Experience in Skylight Construction
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 actually request repairs.
If you are concerned about whether the contractor you are considering will respond adequately, choose one with extensive repair experience.
It can also be effective to look at skylight contractors based on reviews from Google and review sites!
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 construction, so we receive many requests for skylight replacement work.
Confirm if They Can Handle Roofing Work
Since skylights are installed on roofs, roofing work often comes into play.
If the contractor lacks knowledge about roofs or cannot handle roofing work, there is a possibility of 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 simultaneously 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 done free of charge, providing peace of mind!
Additionally, companies that offer warranty periods are often confident in their work, which can serve as a criterion for selecting a contractor!
The warranty period varies depending on the contractor and the scope of work, but it typically ranges 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 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 such as partial sealing.
Obtain estimates from multiple contractors (at least 3)
When requesting skylight work, let’s obtain estimates from multiple contractors.
Even for the same repair or replacement work, the costs can 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 contractor at a lower price, it is essential to obtain estimates from multiple contractors.
When comparing estimates, consider not just the costs, but also
“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 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 content of the plan will vary depending on the actual state of deterioration and the customer’s wishes.
If you choose a contractor that completely outsources skylight repair work, they may lack knowledge and experience, leading to proposals for repairs in inappropriate areas or unnecessary work.
There are cases where customers who want to keep costs down are proposed skylight replacements, even though partial repairs would suffice.
Additionally, since the investigation is followed by a request to a subcontractor, both time and costs will inevitably increase.
By having knowledge and experience and conducting 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 response times during emergencies, such as post-construction troubles, tend to be slower.
