To conclude, the most important thing when considering large-scale repairs is
“multiple estimates”!
Let’s obtain at least 3 estimates from large-scale repair companies that cover Setagaya-ku!
Reasons why Kakeru Koumuten is chosen for large-scale repairs in Setagaya-ku, Tokyo
One reason why we are entrusted with large-scale repairs in Setagaya-ku is that
“Our unique approach to large-scale repair work that cannot be imitated by other companies”
has received high praise from many customers.
“costs,” “quality,” and “plans” for exterior renovations of apartments, condominiums, and commercial facilities in Setagaya-ku, 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 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 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 can be achieved in waste disposal fees.
Exterior Renovation Dedicated Showroom
In the showroom, not only can you have meetings, but you can also
check actual exterior material samples and colors.
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 inquiry 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 project completion.
Since the person in charge does not change, 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, and tile repairs with our own staff!
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 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 warranty 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 using 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 enhance 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 we also install bulletin boards at entrances to display progress charts and announcements!
Additionally, we ensure that the manners of visitors are thoroughly educated to minimize 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 missed.
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 directly from our company 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 the simulation on your smartphone or computer.
By simulating and then applying two-tone colors or making image changes, we hope to help enhance your 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
Exterior simulations for apartments and condominiums are also possible!
・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
・Simulations for roof painting and roof replacement work are also possible
By using exterior renovation simulations, you can significantly reduce the risk of failure in image changes!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

Case Study of Exterior Renovation Work on a Mixed-Use Building
| Construction Details |
| Partial replacement of damaged tiles Painting of auxiliary parts (pipes, water drainage) 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 auxiliary 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 |
| Process Leading to Construction |
| Due to leaks occurring from several areas such as the exterior walls and rooftop, we proposed waterproofing for the entire exterior. The Seven S is a clear waterproofing material for tile exterior walls, and while the cost is somewhat higher, its waterproofing performance is excellent. Therefore, if leaks are occurring from several areas of the exterior wall, it is a recommended waterproofing material. |
How to Choose a Large-Scale Renovation Contractor
There are many large-scale renovation contractors available in Setagaya-ku, Tokyo, and you may be unsure which contractor to choose.
For this reason, when requesting renovations for apartments, condominiums, and buildings, it is important 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 reliable contractor.
Extensive Experience in Large-Scale Renovations
Large-scale renovation contractors often have websites that showcase their exterior renovation projects.
Additionally, if they provide detailed explanations of the repair work with accompanying photos, it offers reassurance 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 to look at skylight installation contractors!
If there are many negative reviews or no reviews at all, it may be wise to refrain from requesting their services.
Large-scale renovation 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 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 renovation 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, making this a key criterion for selecting a contractor!
Warranty periods vary by contractor and type of work, but typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Furthermore, 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.
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 renovations, 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, it is essential to obtain estimates from multiple contractors.
When comparing estimates, consider not only the cost but also
“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 the 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, since it is not easily visible from the outside, be sure to check whether the repair method is appropriate for the condition of the substrate!
Check if it’s 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 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 the subcontractor.
By having knowledge and experience and managing in-house, responsible construction can be achieved 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 delayed.
It is safer to avoid having a company that has not actually met with the customer manage 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!
