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 the Kamakura area!

Reasons why Kakeru Koumuten is chosen for skylight construction in Kamakura

One reason we are entrusted with skylight repairs in Kamakura is that
“being a roofing company in Kanagawa Prefecture” is one of the reasons,
“our unique approach to skylight replacement work that cannot be imitated by other companies”
has received high praise from many customers.

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 reduce scaffolding costs 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, 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 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 assist you from the estimate to the completion of the project.
Since the same person handles everything, including sales and 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 in-house construction!

Since skylight installation involves dismantling or removing roofing materials, it can significantly reduce costs when done simultaneously with roof 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 on staff, and we are confident in our construction techniques.
We are also capable of handling large-scale roofing projects for factories and other facilities!
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.

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

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 improvement education to ensure all staff can respond effectively.

Subsidies and Grants Available for Skylight Construction in Kamakura City

In Kamakura City, 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 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 work must target existing homes in the prefecture and utilize products with insulation performance specified by the national government, such as windows, glass, and insulation materials. 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 renovation work includes insulation improvements 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 for eligible energy efficiency renovation work, 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 limit of 200,000 yen, the amount granted will be “up to the maximum limit.”

Child-Rearing Green Housing Support Project

Eligible Applicants

Households with children (households with children under 18) and young couples are eligible for new construction or purchase of homes with high energy efficiency performance, or energy-efficient renovations of existing homes. In the case of new construction, 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 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 home’s energy efficiency, such as insulation renovations or the introduction of energy-saving equipment. In both cases, it is necessary to contract with a registered business and complete 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, depending on the type of work. In either case, even if multiple works are carried out, 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 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.

Advanced Window Renovation Project

Eligible Participants

Owners of existing homes (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” recognized by the government, and the granted subsidy is fully refunded to the homeowners through discounts on the construction costs.

Requirements

Eligible works include window renovations aimed at improving insulation performance, such as installing interior windows, replacing exterior windows, and exchanging glass 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 start 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.

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 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, 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. After all, since it involves opening up the roof, there is a certain risk of leaks.

However, with proper installation and regular maintenance of modern skylights, this risk can be minimized significantly.

Regular Maintenance Required

Skylights need maintenance every 5 to 10 years to prevent leaks. While maintenance may seem troublesome, 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 be transmitted indoors, which is a disadvantage. In particular, the sound can be quite noticeable during heavy rain or typhoons.

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.

How to Choose a Skylight Contractor

There are many skylight contractors in Kamakura 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.

By checking these 5 points, you will be able to choose a reliable contractor.

Have Extensive Experience in Skylight Work

Skylight contractors often have websites showcasing their project achievements.

Additionally, if they provide detailed explanations of repair work with photos, it can give you peace of mind 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 is also effective to refer to reviews on Google and review sites when looking 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 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 may lead to problems such as leaks after installation or high construction costs.

Moreover, skylight replacement or removal may require partial dismantling of the roof and restoration, so 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 our customers’ needs for roofing work associated with skylight installation.

Check for warranties and after-sales maintenance

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 done free of charge, providing peace of mind!
Additionally, companies that offer a warranty demonstrate confidence in their work, serving as a 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 after-sales services in addition to warranties, so be sure to check if the contractor you are considering has warranties and after-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)

When requesting skylight installation, obtain estimates from multiple contractors.

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

When comparing estimates, consider not just the costs, but also
“Items in the estimate”
“Materials and quality of glass, etc.”
“Verification 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!

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 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 to replace the skylight instead of a partial repair that would suffice.

Additionally, since the contractor will investigate and then request a subcontractor, it can take extra time and cost.
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 outsource work, one of the disadvantages is that their response to emergencies or post-construction issues tends to be delayed.
