Reasons why Kakeru Koumuten is chosen for large-scale repairs in Akiro City, Tokyo
One reason why we are entrusted with large-scale repairs in Akiro City is that
Kakeru Koumuten Co., Ltd. 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 Akiro City, Tokyo,
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 repairs.
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 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!
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, since we always have stock available, we can provide swift responses in emergencies!
In-house Waste Separation
In large-scale renovations, various waste materials such as leftover paint, metal, and wood are generated.
Most contractors dispose of them all together, but by sorting and recycling waste materials, significant cost reductions in waste disposal fees 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 in a consistent system, 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 possible.
We can handle everything from temporary scaffolding installation to exterior wall painting, substrate repair, waterproofing work, and tile repairs with complete in-house construction!
Professionals with specialized knowledge and experience will conduct inspections and actual construction for each process!
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 technicians on staff, giving us confidence in our construction techniques.
We are capable of handling large-scale roofing projects for factories and other facilities!
We also 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 guarantees for almost all types of work, including “painting work,” “substrate repair work,” and “waterproofing work”!
After-sales 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 inspected 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!
We will promptly respond to urgent requests or emergencies!
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 during each phase of large-scale repair work.
7. Consideration for Residents and Neighbors
During large-scale repair work, we not only notify residents and visit neighbors to explain the work, but we also install bulletin boards at entrances to display the work 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 phase 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 missed.
During exterior wall painting and 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 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 you achieve 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 conduct test painting on your exterior wall.
By performing a test painting, you can confirm the actual color and sheen!
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 and roof replacement work is also possible
With exterior renovation simulations, you can significantly reduce the risk of failure in image changes!

Case Study of Exterior Renovation Work on a Mixed-Use Building
| Construction Details |
| Partial replacement of damaged tiles Painting of ancillary parts (pipes, water cut-off) Roof waterproofing work (urethane waterproofing) Exterior wall tile waterproofing (Seven S) Sealing work around sashes Repair of exterior wall tile mortar joints Removal of ivy |
| New Materials Used |
| Exterior wall tiles: Kunishiro tiles Painting of ancillary parts: Radical silicon paint Roof waterproofing: High-strength urethane (Sarasene A) Exterior wall tile waterproofing: Seven S |
| 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 rooftop, 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 capability makes it a recommended material 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 Akiro City, Tokyo, and it can be confusing to decide which contractor to choose.
For this reason, when requesting renovations for apartments, condominiums, and buildings, be 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)
● Verify 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 that showcase their track record in exterior renovations.
Additionally, if they provide detailed explanations of the 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 about to hire will respond adequately, choose a contractor with extensive experience in large-scale renovations.
It can also be effective to refer to reviews on Google and review sites when looking at skylight installation contractors!
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 necessary to prevent issues in advance by reporting the progress of the work and sharing information about laundry, etc., on bulletin boards.
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 can be seen as having 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 it is generally set between 1 to 10 years.
Emergency repairs or partial repairs often do not come with a leak warranty.
Moreover, some contractors offer after-sales services separately 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 for after-sales maintenance, allowing for yearly inspections.
We also provide free support 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 get estimates from at least 3 companies and compare their reports and estimates!
Even for the same type of work, repair costs, warranties, and after-sales services can vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred repair contractor at the best possible 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 substrate repair 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 substrate repair work, which can be difficult to assess from appearance, make sure to verify whether the repair method is appropriate for the condition of the substrate!
Check if it is managed in-house
Large-scale renovation work includes various types of construction such as “substrate repair work,” “exterior wall painting,” “waterproofing work,” and “pipe replacement”!
The content of the plan will change 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 in-house, responsible construction can be carried out while keeping costs down.
Additionally, one of the drawbacks of contractors that outsource is that if any trouble occurs during construction, their response may be slow.
It is prudent to avoid having a company that has not actually met with the customer manage the construction.
Kakeru Koumuten Co., Ltd. is a company that conducts everything from temporary scaffolding installation to exterior wall painting and waterproofing work in-house.
Knowledgeable and experienced personnel will manage the construction!
