“costs,” “quality,” and “plans” for exterior renovations of apartments, condominiums, and commercial facilities in Katsushika-ku, Yokohama,
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 renovations.
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 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 enough scaffolding materials for approximately 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 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 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.
Color simulations for exterior wall painting and confirmation of heat insulation properties using heat insulation testing equipment are also available!
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 manage sales and construction, 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!
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 technicians on staff, giving us confidence 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 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”!
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 utilize drones to inspect exterior walls and rooftops that cannot be checked from high places!
During leak investigations, we can use a thermal imaging camera, which helps in identifying the cause of leaks!
We will respond according to our customers’ wishes.
We also accept emergency measures for sudden 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 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 greet neighbors, but also install bulletin boards at entrances to display the project schedule and announcements!
Additionally, we ensure that the manners of visitors are well-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 conducting 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 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 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 sheen!
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
With 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.

| 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 the roof, we proposed waterproofing for the entire exterior wall. The Seven S is a clear waterproofing material for tile exterior walls, and while the cost is somewhat high, it offers excellent waterproofing. 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 that cover Katsushika-ku, Tokyo, and it can be confusing to decide which contractor to choose.
For this reason, 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 guarantees 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 remodeling achievements.
Additionally, if they provide detailed explanations of the repair work 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 on Google and review sites when looking for 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 not only involves the construction itself but also tends to lead to troubles with residents and neighboring residents. Therefore, it is necessary to prevent issues 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 construction, 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 type of 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 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 as part of our 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 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 a lower price, obtaining estimates from multiple contractors is essential.
When comparing estimates, consider not only the costs, but also
“Items in the estimate”
“Methods and materials for base 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 steps are skipped, costs can be reduced, so avoid making decisions based solely on price!
Especially regarding base repair work, since it may not be obvious from the appearance, ensure that the repair method is appropriate for the condition of the base!
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 plan details will vary depending on the actual state of deterioration and the customer’s wishes.
If a contractor completely outsources the large-scale renovation work to subcontractors, they may lack knowledge and experience, leading to proposals for repairs in inappropriate areas or unnecessary work.
This can also 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, 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 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!
