Reasons why Kakeru Koumuten is chosen for large-scale repairs in Tachikawa City, Tokyo
One reason why we are entrusted with large-scale repairs in Tachikawa City 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.
“cost,” “quality,” and “plans” for exterior renovations of apartments, condominiums, and commercial facilities in Tachikawa 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 procure materials at a lower cost!
Additionally, we always have stock available, allowing for swift responses in emergencies!
In-house Waste Separation
During 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 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 thermal 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.
By managing everything from inquiries to project completion in a consistent system, we can keep costs down while delivering high-quality large-scale repairs.
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 manager, 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!
Specialists with knowledge and experience will conduct inspections and actual construction for each process!
3. Various Permits and Skilled Workers
We have obtained permits for the construction industry and for the collection and transportation of industrial waste!
We also have nationally certified sheet metal workers and painting specialists on staff, so we are confident in our construction techniques.
We can also handle 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 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 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 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 be careful about 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 visit neighbors to greet and explain the work, but we also install bulletin boards at entrances to display the work 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 performing exterior wall painting or waterproofing work, we confirm 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 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 test painting, you can confirm the actual color and gloss!
9-3 Exterior Renovation Simulation
We can also perform the following exterior simulations for apartments and condominiums!
・Exterior wall color simulation (two-tone colors are also possible)
・Simulation for when metal siding is applied
・Simulation using accent materials such as cornices and louvers
・Simulation for roof painting and roof replacement work is also possible
The risk of failure in image changes through exterior renovation simulations can be minimized!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

| Partial replacement of damaged tiles Painting of ancillary parts (pipes, drip edges) 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 silicone 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 |
| Construction Background |
| Due to leaks occurring from several areas such as the exterior walls and the rooftop, we proposed waterproofing for the entire exterior wall. Seven S is a clear waterproofing material for tile exterior walls, and while it is somewhat expensive, its high waterproofing performance 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 Tachikawa City, Tokyo, and it can be confusing to decide which one to choose.
Therefore, when requesting renovations for apartments, condominiums, and buildings, let’s 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 reliable contractor.
Extensive Experience in Large-Scale Renovations
Large-scale renovation contractors often have websites that showcase their exterior renovation achievements.
Additionally, if they provide detailed explanations of repair contents with photos, it gives you 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 one with extensive experience in large-scale renovations.
It is also effective to refer to reviews of skylight 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 disputes with residents and neighboring residents. Therefore, it is necessary to prevent troubles 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 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 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 for after-sales maintenance, allowing for yearly inspections.
We 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 three companies and compare their estimates and reports!
Even for the same work, repair costs can vary between contractors, as well as 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, consider not only the cost but also
“Items in the estimate”
“Methods and materials for substrate repair work and exterior wall painting”
“Confirmation of the process”
and make detailed comparisons for your judgment! 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!
Particularly for substrate repair work, it can be difficult to assess from the appearance, so be 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 tasks such as “substrate repair work,” “exterior wall painting,” “waterproofing work,” and “pipe replacement!”
The plan details will change based on the actual deterioration condition and the customer’s wishes.
If a contractor completely outsources to subcontractors, they may lack knowledge and experience, leading to proposals for repairs in inappropriate areas or unnecessary work.
This can result in additional time and costs as you will need to investigate before requesting subcontractors.
By having knowledge and experience and managing in-house, responsible construction can be carried out while keeping costs down.
Additionally, if a contractor is outsourcing to subcontractors, one of the drawbacks is that their response may be slow in case of any trouble during construction.
It is safer to avoid having a company that has not actually met with the customer manage the construction.
Kakeru Koumuten Co., Ltd. is a company that carries out everything from temporary scaffolding installation to exterior wall painting and waterproofing work in-house.
Knowledgeable and experienced personnel will manage the construction!
