To conclude, the most important thing when considering skylight work is
“getting multiple estimates”!
Let’s obtain at least three estimates from skylight repair contractors that cover Aoba-ku, Yokohama!

Reasons why Kakeru Koumuten is chosen for skylight work in Aoba-ku, Yokohama

One reason why you can trust us with skylight repairs in Aoba-ku, Yokohama
is that “Kakeru Koumuten is a roofing company in Tokyo,”
but we also have “our unique approach to skylight replacement work that cannot be imitated by other companies”
, which has received high praise from many customers.

For skylight replacement work in Aoba-ku, Yokohama,
“costs,” “quality,” and “plans” are our absolute strengths,

and we would be grateful if you could compare them with estimates from other companies.

We are confident, so we welcome price comparisons.

1. Equipment Specialized in Exterior Renovation

Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage 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 assemble 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 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 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 project completion.
Since the person in charge does not change, whether it’s the sales representative or the construction management representative, smooth communication is possible.

We can handle everything from the installation of temporary scaffolding to exterior painting, roofing work, and exterior cover work completely in-house!

Since skylight installation involves dismantling or peeling off roofing materials, performing it simultaneously with roof replacement or cover work can significantly reduce costs!

3. Various permits obtained and skilled workers on staff

We have obtained construction industry licenses and permits for industrial waste collection and transportation!
We have qualified professionals such as national certified sheet metal workers and painting technicians, and we are confident in our construction techniques.
We are also capable of handling large-scale roofing projects for factories and similar structures!
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 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

We are creating various roof models by ourselves to improve our skills and conducting practical training.
Since different processing and techniques are required depending on the site, we regularly provide skill enhancement training so that each staff member can respond appropriately.

Subsidies and Grants That May Be Applicable for Skylight Construction in Minato-ku, Tokyo

In Minato-ku, Tokyo, there are potential subsidies available when carrying out skylight construction!
For details, please contact our company or your local government!

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 energy-efficient homes, or energy-saving renovations of existing homes. For new construction, the builder or purchaser is eligible, while for renovations, the contractor who orders the work 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. For renovations, it is required to carry out work that improves the energy-saving performance of the home, such as insulation upgrades or the introduction of energy-saving equipment. In both cases, it is necessary to contract with a registered business and carry out the work within the specified period.

Maximum Subsidy Amount

For new construction, the maximum subsidy per unit ranges from 400,000 yen to 1,600,000 yen depending on the performance category of the house, while for renovations, the maximum subsidy per unit ranges from 400,000 yen to 600,000 yen depending on the content of the work. In either case, even if multiple works are carried out, the total subsidy cannot exceed this maximum amount.

Subsidy Rate

This project does not provide a subsidy based on a certain percentage of the construction cost; instead, a predetermined “fixed subsidy” is provided based on the content of the work and performance categories. Therefore, in effect, the government bears part of the construction cost.

For more details, please see here!

Advanced Window Renovation Project

Eligible Applicants

Owners of existing homes (single-family homes and apartment buildings) who are carrying out insulation renovation work on windows and openings are eligible. The actual application process for the subsidy 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

The eligible work includes window renovation aimed at improving insulation performance, such as installing interior windows, replacing exterior windows, and replacing 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 amount of the subsidy must be 50,000 yen or more, and the work must start and be completed within the specified construction period.

Maximum Subsidy Amount

The maximum subsidy is 2 million yen per household. Even if multiple windows are renovated, the total subsidy that can be received for the same residence will be up to this maximum amount.

Subsidy Rate

The subsidy rate is approximately half of the construction cost. The actual subsidy amount is set at a fixed rate based on the type of window (inner window, outer window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction cost.

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 it feel pleasant.

Energy Savings

This is also related to the high light transmission, as having natural light allows you to save on electricity costs. It reduces the need to turn on lights during the day, making it energy-efficient.

Good Ventilation

By installing a skylight, you can open and close it, improving ventilation.
Warm air rises, enhancing airflow.

High Privacy

In areas with closely built houses, large windows can expose the interior of your home. In such cases, skylights are installed on the roof, ensuring 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 the roof for installation, 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 do it regularly to avoid damage to the interior and wooden parts due to leaks.

Noise from Rain

Since skylights are installed directly on the roof, the sound of raindrops hitting the glass can easily be transmitted indoors. This noise can be particularly noticeable during heavy rain or storms.

However, this is not strongly felt with all skylights. By choosing double-glazed glass or products with high sound insulation, the sound of rain can be reduced.

Background to the Construction

Due to cracks in the skylight glass, we received a request to replace the skylight glass along with the roof overlay work.

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.
We will take measures to prevent debris from falling indoors.

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 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 were holding the glass in place.
It is important to ensure that the method used matches the type of skylight being installed, as improper installation could lead to leaks. We will check that the fittings are securely fastened.
We will perform waterproofing treatment around the frame with sealing.

How to Choose a Skylight Contractor

There are many skylight contractors in Tokyo, and it can be confusing to decide which one to choose.

Therefore, when requesting skylight replacement work or leak repairs, please 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 companies).

● Confirm if they perform roof renovations in-house.

By checking 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 when you decide to 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 is also effective to refer to reviews on Google and review sites to find skylight contractors!
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 also handle roofing work.

Since skylights are installed on roofs, roofing work is often involved as well.
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.

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 tailored to your needs for roofing work related to 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, a company that offers a warranty is a sign of confidence in their work, which can serve as a criterion for selecting a contractor!

The warranty period varies by contractor and the nature of the 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 it’s important to check whether the contractor you are considering has warranties and aftercare services.

At Kakeru Koumuten Co., Ltd., we send out annual DM for aftercare maintenance, allowing for yearly inspections.
We also provide free support for simple repairs like partial sealing.

Obtain estimates from multiple contractors (at least 3)

When requesting skylight installation, make sure to obtain estimates from multiple contractors.

Even for the same repair or replacement work, the costs can vary between contractors, as can the warranties and aftercare services.

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 multiple contractors.

When comparing estimates, consider not just the costs, but also
“Items in the estimate”
“Materials and quality, such as 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!

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 the wrong areas or unnecessary work.
Customers who want to keep costs down may be suggested to replace the skylight, even though a partial repair would suffice.

Additionally, since they will request subcontractors after an investigation, both time and costs will increase.
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 drawbacks is that their response to emergencies, such as post-construction issues, tends to be slow.
