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 Nishitama-gun!
Reasons why Kakeru Koumuten is chosen for large-scale repairs in Nishitama-gun, Tokyo
One reason why we are entrusted with large-scale repairs in Nishitama-gun
is that “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” are our absolute strengths,
1. Equipment specialized in 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 not outsourcing scaffolding work and using our own scaffolding team, 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, enabling us to provide swift responses in emergencies!
In-house Waste Sorting
In large-scale renovations, various waste materials such as leftover paint, metal, and wood are generated.
While most contractors dispose of them all together, separating and recycling waste materials can significantly cut waste disposal costs.
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 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 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, and tile repairs with complete in-house construction!
Qualified professionals with specialized knowledge and experience 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 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 address exterior walls and rooftops that cannot be checked from high places using 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!
In emergencies or urgent requests, we will respond promptly!
6. Human Resource Development
Our staff creates various models for skill enhancement and conducts practical training.
Since different processing and techniques are required depending on the site, we regularly provide skill improvement education 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 project schedules 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 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 check the number of used paint cans to confirm that the specified amount of paint is being 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 actual photos of your apartment or building!
You can also perform the simulation on your smartphone or computer.
By simulating and then applying two-tone colors or making a change in 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 Sample Painting!
You can order samples of the paint you are considering and perform sample painting on your exterior walls.
By doing a sample 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 for when accent materials like cornices and louvers are used
・Simulation for roof painting or roof replacement work is also possible
With the exterior renovation simulation, you can significantly reduce the risk of failure in changing the image!
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 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 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 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 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 Nishitama-gun, 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)
● Confirm whether 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 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 properly, choose one 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 requesting their services.
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 providing 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-service 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 free of charge, 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-service maintenance separately from warranties, so be sure to confirm whether the contractor you are considering has warranties and after-service maintenance.
Kakeru Koumuten Co., Ltd. sends out annual direct mail as part of our after-service maintenance, allowing for yearly inspections.
We also provide free support for simple repairs such as partial sealing.
Obtain estimates from multiple contractors (at least three)
When requesting large-scale repairs, obtain estimates from multiple contractors.
It is important to acquire 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-service maintenance may differ between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at the lowest possible price, obtaining estimates from multiple contractors is essential.
When comparing estimates, consider not only the cost but also
“the items in the estimate”
“the 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!
Particularly for base repair work, which can be difficult to assess from appearance, ensure that the repair method is suitable for the condition of the base!
Confirm whether 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 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 need to investigate before requesting a subcontractor.
By having knowledge and experience and managing in-house, responsible construction can be carried out at a reduced cost.
Additionally, contractors that outsource to subcontractors may also have delayed responses in the event of any trouble during construction, which is one of the disadvantages.
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!
