These topics will definitely be helpful for owners and management associations
considering repairs or exterior renovations for their apartments and condominiums, so please take a look!
To conclude, the most important thing when considering large-scale repairs is
“multiple estimates”!
Let’s obtain at least three estimates from large-scale repair companies that cover Suginami-ku!
Reasons why Kakeru Koumuten is chosen for large-scale repairs in Suginami-ku, Tokyo
One reason why we are entrusted with large-scale repairs in Suginami-ku 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.
“costs,” “quality,” and “plans” for exterior renovations of apartments, condominiums, and commercial facilities in Suginami-ku, Tokyo,
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.
In-house Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for large-scale renovations, allowing us to assemble the scaffolding in-house.
By not outsourcing scaffolding work and using our own scaffolding team, we can cut costs on scaffolding construction 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 us to provide swift responses even in emergencies!
In-house Waste Separation
In large-scale renovations, various waste materials such as leftover paint, metal, and wood are generated.
While most contractors dispose of them all together, 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 heat insulation properties using a heat insulation testing machine!
2. Cost Reduction through In-House Management and Construction
One of Kakeru Koumuten Co., Ltd.’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 repairs, waterproofing, 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, so we are confident in our construction techniques.
We can also handle large-scale roofing projects for factories and other facilities!
Qualified asbestos supervisors and asbestos surveyors are also on staff, enabling 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 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!
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 each staff member can respond appropriately.
We also educate on points to pay attention to 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 we also install bulletin boards at entrances to display the work schedule and announcements!
Additionally, we ensure thorough etiquette training for visitors to minimize any inconvenience to residents and neighbors.
8. Strict Quality Control
Each stage of work 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 there are no oversights.
When performing exterior wall painting or waterproofing work, we confirm the quantity of used paint cans to ensure 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 we create can be done using actual photos of your 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 enhance the stylish appearance and help 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 paints 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 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, the risk of failure in image changes can be minimized!
We hope that by renovating the appearance of your apartment or condominium, it will help increase occupancy rates.

| Price Range |
| 4,000,000 to 4,100,000 yen |
| Construction Period |
| 45 days |
| Progress Before Construction |
| Due to leaks occurring from several areas such as the exterior walls and the roof, we proposed waterproofing for the entire exterior wall. 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 that cover Suginami-ku, 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
● Check for 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 offers 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 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 making a request.
Large-scale repair work involves not only the construction itself but also the potential for troubles with residents and neighboring inhabitants. 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 work, and we receive many requests for exterior renovations of apartments and condominiums.
Check for warranties and aftercare services
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 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 aftercare services in addition to warranties, so be sure to check if the contractor you are considering has warranties and aftercare services.
Kakeru Koumuten Co., Ltd. sends out annual direct mail as part of our aftercare service,
allowing for yearly inspections.
We also provide free assistance 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 acquire estimates from at least three companies and compare their estimates and reports!
Even for the same type of work, repair costs, warranties, and aftercare 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, 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 visually, ensure that the repair method is appropriate for the condition of the substrate!
Check if the company is self-managed
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 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, if a contractor is outsourcing to subcontractors, one of the disadvantages is that their response may be slow in case of any troubles 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 performs everything from temporary scaffolding installation to exterior wall painting and waterproofing work in-house.
Knowledgeable and experienced personnel will manage the construction!
