Reasons why Kakeru Koumuten is chosen for large-scale repairs in Kiyose City, Tokyo

Kakeru Koumuten is based in Tokyo, but
“Our unique approach to large-scale repair work that cannot be imitated by other companies”
has received high praise from many customers.
“cost,” “quality,” and “plans” for exterior renovations of apartments, condominiums, and commercial facilities in Kiyose City, Tokyo,
1. Equipment specialized for exterior renovations
At Kakeru Koumuten Co., Ltd., we have organized the following warehouses and material storage areas to provide low-cost, high-quality exterior wall painting and waterproofing work for large-scale repairs.
We have established five 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 repairs, 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 provide quick and flexible responses.
We have approximately enough scaffolding materials for 100 single-family homes!
Material Storage 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 these materials together, by sorting and recycling waste materials, significant cost reductions in 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 its in-house management and construction.
From inquiries to project completion, everything is managed by Kakeru Koumuten in a consistent system, allowing for high-quality large-scale repairs at reduced costs.
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 possible.
We can fully handle everything from temporary scaffolding installation to exterior wall painting, substrate repair, waterproofing work, and tile repairs with our own staff!
Qualified professionals with specialized knowledge and experience will conduct inspections and actual construction at each stage!
3. Various Permits and Skilled Workers
We have obtained construction industry permits and permits for 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 preliminary surveys.
4. Warranty and Aftercare
Most large-scale repair works come with a guarantee 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, which helps in identifying 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 depending on the 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 at 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 schedule and announcements!
Additionally, we thoroughly educate entrants on manners 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 it comes to exterior painting and waterproofing work, we confirm the quantity of used paint cans to ensure that the specified amount of paint is used, and we prevent construction defects by ordering paint in-house.
Of course, we also take photos of the used paint and report them accordingly.
9. Color Simulation for Exterior Wall Painting
9-1 Self Color Simulation
The simulations created by our company can be done using actual photos of your apartment or building!
You can also perform the simulation on your smartphone or computer.
By simulating and then applying a two-tone color or changing the image, we hope to help enhance the 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 conduct test painting on your exterior walls.
By doing a test painting, you can confirm the actual color and gloss!
9-3 Exterior Renovation Simulation
We can also provide 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 or roof replacement work is also possible
With the exterior renovation simulation, the risk of failure in image change can be minimized!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

| Price Range |
| 4,000,000 – 4,100,000 yen |
| Construction Period |
| 45 days |
| Process Leading to Construction |
| Due to leaks occurring from several areas such as the exterior walls and the roof, we proposed waterproofing for the entire exterior wall. The Seven S is a clear waterproofing material for tile exterior walls, and while it is somewhat expensive, its high waterproofing ability makes it a recommended choice if leaks are occurring from multiple areas of the exterior wall. |
How to Choose a Large-Scale Renovation Contractor
There are many large-scale renovation contractors that cover Kiyose City, Tokyo, and it can be confusing to decide which one to choose.
Therefore, when requesting renovations for apartments, condominiums, and buildings, make sure to check the following four points:
● Extensive experience in large-scale renovations
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least three)
● Check if they are self-managed
By confirming the above four points, you will be able to choose a trustworthy contractor.
Extensive Experience in Large-Scale Renovations
Large-scale renovation contractors often have websites showcasing their track record in exterior renovations.
Additionally, if they provide detailed explanations of repair contents with photos, it offers reassurance as a reference when you actually request repairs.
If you are concerned about whether the contractor you are about to request will respond adequately, choose a contractor with extensive experience in large-scale renovations.
It is also 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 making a request.
Large-scale repair work involves not only the construction itself but also the potential for troubles with residents and nearby neighbors. Therefore, it is essential to prevent issues in advance by reporting the progress of the work and providing information about laundry through bulletin boards and other means.
Kakeru Koumuten Co., Ltd. specializes in exterior work, 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 work is completed, having a leak warranty from the contractor ensures that repairs can be made at no cost, providing peace of mind!
Additionally, companies that offer warranty periods demonstrate confidence 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 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.
At Kakeru Koumuten Co., Ltd., we send out annual direct mail as part of our after-sales maintenance, allowing for yearly inspections.
For simple repairs such as partial sealing, we provide services free of charge.
Obtain estimates from multiple contractors (at least three)
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 can vary between contractors, as can warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, obtaining estimates from multiple contractors is essential.
When comparing estimates, it is important to look at more than just the cost,
“Items in the estimate”
“Methods and materials for base repair work and exterior wall painting”
“Confirmation of the process”
and make detailed comparisons! 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 base repair work, which may not be easily visible from the outside, be sure to confirm whether the repair method is appropriate for the condition of the base!
Check if the company is self-managed
Large-scale renovation work includes various types of construction such as “substructure repair work,” “exterior wall painting,” “waterproofing work,” and “pipe replacement!”
The content of the plan 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. handles everything from temporary scaffolding installation to exterior wall painting and waterproofing work in-house.
Knowledgeable and experienced personnel will manage the construction!
