Reasons Why Kakeru Koumuten is Chosen for Large-Scale Repairs in Taito-ku, Tokyo

One reason why we are entrusted with large-scale repairs in Taito-ku is that
“the fact that Kakeru Koumuten is based in Tokyo” is one reason, but
“Our unique approach to large-scale repair work that cannot be imitated by other companies”
has received high praise from many customers.

1. Equipment Specialized for Exterior Renovations

At Kakeru Koumuten Co., Ltd., we have prepared the following warehouses and material storage areas to provide low-cost, high-quality exterior wall painting and waterproofing work for large-scale renovations.
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 large-scale renovations, 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 provide quick and flexible responses.
We have approximately enough scaffolding materials for 100 single-family homes!

Storage of Materials in Our Large Warehouse

We store paints and base repair 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 provide swift responses even in emergencies!

In-house Waste Separation

In large-scale renovations, various waste materials such as leftover paint, metal, and wood are generated.
While most contractors dispose of them all together, by sorting and recycling waste materials, significant cost reductions on waste disposal can be achieved.

Exterior Renovation Dedicated Showroom

In the showroom, not only can you have meetings, but you can also
check actual samples and colors of exterior materials.
You can also perform color simulations for exterior wall painting and check heat insulation properties using a heat insulation testing machine!

2. Cost Reduction through In-House Management and Construction

One of Kakeru Koumuten’s major strengths is our in-house management and construction.

From inquiries to project completion, everything is managed by Kakeru Koumuten, allowing us to keep costs down while providing high-quality large-scale repairs.
Additionally, one representative will handle everything from the estimate to the completion of the work.
Since the same person will be in charge, whether it’s sales or construction management, smooth communication is ensured.

We can handle everything from temporary scaffolding installation to exterior wall painting, substrate repair, waterproofing work, and tile repairs completely in-house!
Qualified professionals with specialized knowledge and experience will conduct inspections and actual construction for each process!

3. Various Permits and Skilled Workers

We have obtained permits for construction work and industrial waste collection and transportation!
We also have nationally certified sheet metal workers and painting specialists on staff, giving us confidence in our construction techniques.
We are capable of handling large-scale roofing projects for factories and other facilities!
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

Most large-scale repair works come with guarantees for almost all types of work, including “painting work,” “substrate repair work,” and “waterproofing work”!

Aftercare maintenance 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 apartments and condominiums.

We can also address exterior walls and rooftops that cannot be checked from high places by utilizing drones!
During rain leak investigations, we can use a thermal imaging camera to help identify the cause of leaks!

We will respond according to your wishes.
We also accept emergency measures for sudden rain leaks!

In emergencies or urgent requests, we will respond promptly!

6. Human Resource Development

Our staff creates various models to improve their skills and conducts practical training.
Since different processing and techniques are required at each site, we regularly provide skill enhancement training to ensure that each staff member can respond appropriately.
We also educate on points to pay attention to and areas to check during each stage of large-scale repair work.

7. Consideration for Residents and Neighbors

During large-scale repair work, we not only notify residents and greet neighbors, but also install bulletin boards at entrances to display the construction schedule and announcements!
Additionally, we ensure that the manners of visitors are thoroughly educated to minimize any inconvenience to residents and neighbors.

8. Strict Quality Control

Each stage is inspected by a responsible person, and detailed construction photos are taken.
We use film thickness testing equipment and check sheets during inspections to ensure that no inspections are overlooked.
When performing exterior wall painting or waterproofing work, we verify the quantity of used paint cans to ensure that the specified amount of paint is used, and we order paint in-house to prevent construction defects.
Of course, we also take photos of the used paint and report them accordingly.

9. Exterior Wall Painting Color Simulation

9-1 Self Color Simulation

 
The simulations created by our company can be done using photos of your actual apartment or building!
You can also perform simulations on your smartphone or computer.
By simulating and then applying two-tone colors or making image changes, we hope to help create a stylish appearance and increase occupancy rates!

Of course, we can also arrange for paint samples to confirm the actual colors.

9-2 Confirm Actual Colors with Test Painting!

You can order samples of the paint you are considering and perform test painting on your exterior walls.
By conducting a test painting, you can confirm the actual color and gloss!

9-3 Exterior Renovation Simulation

We can also perform exterior simulations for apartments and condominiums as follows!
・Exterior wall color simulation (two-tone colors are also possible)
・Simulation for when metal siding is applied
・Simulation using accent materials like cornices and louvers
・Simulation for roof painting and roof replacement work is also possible

The risk of failure in image changes can be greatly reduced with exterior renovation simulations!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

Construction Process

Due to leaks occurring from several areas such as the exterior walls and the rooftop, we proposed waterproofing for the entire exterior. Seven S is a clear waterproofing material for tile exterior walls, and while it is somewhat expensive, its high waterproofing capability makes it a recommended choice when leaks are occurring from multiple areas of the exterior.

How to Choose a Large-Scale Renovation Contractor

There are many large-scale renovation contractors that cover Taito-ku, Tokyo, and it can be confusing to decide which contractor to choose.

Therefore, when requesting renovations for apartments, condominiums, and buildings, make sure to check the following four points:

By confirming the above four points, you will be able to choose a reliable contractor.

Extensive Experience in Large-Scale Renovations

Large-scale renovation contractors often have websites that showcase their exterior renovation project achievements.
Additionally, if they provide detailed explanations of repair contents with photos, it offers peace of mind as a reference when you actually request repairs.

If you are concerned about whether the contractor you are about to request will respond properly, choose a contractor with extensive experience in large-scale renovations.

It can also be effective to refer to reviews of skylight installation contractors on 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.

Large-scale repair work involves not only the construction itself but also the potential for troubles with residents and neighboring residents. Therefore, it is necessary to prevent issues in advance by reporting the progress of the work and sharing information about laundry through bulletin boards and other means.

Kakeru Koumuten Co., Ltd. specializes in exterior construction, and we receive many requests for exterior renovations of apartments and condominiums.

Check for warranties and after-sales maintenance

When choosing a large-scale repair company, make sure to check for warranties.

If any issues such as leaks occur after the construction, having a leak warranty from the contractor ensures that repairs can be made 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!

Warranty periods vary by contractor and the nature of the work, but typically range from 1 to 10 years.
Emergency repairs or partial repairs often do not come with a leak warranty.

Moreover, some contractors offer after-sales services separate from 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 direct mail as part of our after-sales 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 companies)

When requesting large-scale repairs, obtain estimates from multiple contractors.
It is important to obtain estimates from at least three companies and compare their estimates and reports!

Even for the same type of work, repair costs and warranties or after-sales services may differ between contractors.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at the best possible price, obtaining estimates from multiple contractors is essential.

When comparing estimates, consider not only the cost but also
“the items in the estimate”
“the methods and materials for substrate repair and exterior wall painting”
“confirmation of the process”
and make detailed comparisons to make your judgment! 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!
Especially regarding substrate repair work, which can be difficult to assess from the exterior, be sure to verify whether the repair method is appropriate for the condition of the substrate!

Check if the company is self-managed

Large-scale renovation work includes various types of construction such as “substrate repair work,” “exterior wall painting,” “waterproofing work,” and “pipe replacement!”
The plan details will vary depending on the actual state of deterioration and the customer’s wishes.

If a contractor completely outsources to subcontractors, they may lack knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary work.
This can result in additional time and costs as you will need to investigate and then request subcontractors.
By having knowledge and experience and managing the work in-house, responsible construction can be carried out while keeping costs down.

Additionally, one of the disadvantages of contractors that outsource is that if any trouble occurs during construction, their response may be delayed.
It is safer to avoid companies that do not have direct meetings with customers managing the construction.

Kakeru Koumuten Co., Ltd. is a company that performs everything from temporary scaffolding installation to exterior wall painting and waterproofing work in-house.
Knowledgeable and experienced personnel will manage the construction!
