To conclude, the most important thing when considering a large-scale renovation is
“multiple estimates”!
Let’s obtain at least 3 estimates from large-scale renovation companies
that cover Hadano City!
Reasons why Kakeru Koumuten is chosen for large-scale renovations in Hadano City
One reason why we are entrusted with large-scale renovations in Hadano City is that
“Kakeru Koumuten has a base in Kanagawa Prefecture,” but
“Our unique approach to large-scale renovation 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 Hadano City,
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 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 purchase 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.
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 exterior material samples and colors.
Color simulations for exterior wall painting and confirmation of heat insulation properties using a heat insulation testing machine are also possible!
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 the completion of the work.
Since the person in charge does not change, whether it’s the sales representative or the construction management representative, smooth communication is possible.
We can handle everything from temporary scaffolding installation to exterior wall painting, substrate repair, waterproofing work, and tile repair with complete in-house construction!
Those 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!
Qualified asbestos supervisors and asbestos surveyors are also 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 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!
We will promptly respond to urgent requests and 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 greet neighbors, but also set up bulletin boards at entrances to display the schedule and announcements!
Additionally, we ensure that the manners of those entering the site 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 has been 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 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 help create a 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 perform test painting on your exterior walls.
By conducting 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 such as cornices and louvers
・Simulation for roof painting or roof replacement work is also possible
With exterior renovation simulations, the risk of failure in image changes can be minimized!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

Kanagawa Prefecture Existing Housing Energy Conservation Renovation Subsidy
Eligible Applicants
The eligible applicants for this subsidy are owners of existing homes in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible properties must be residences where the owner themselves lives, regardless of whether they are single-family homes or condominiums.
Eligible Works and Conditions
To receive the subsidy, the following requirements must be met. First, it is necessary to carry out energy conservation renovation work using products such as windows, glass, and insulation materials with specified insulation performance designated by the national government for existing homes in the prefecture. Additionally, the residence must ensure seismic performance, and a prior application must be submitted before starting the work, with construction commencing only after receiving a grant decision. Eligible works include insulation renovations for windows, floors, walls, and ceilings.
Subsidy Amount
The maximum amount for this subsidy is up to 200,000 yen per residence. This is the total subsidy provided when eligible energy conservation renovation work is carried out, and no more than this amount can be received.
Subsidy Rate
The burden ratio for the subsidy is **one-third (approximately 33%) of the eligible construction costs**. However, even if the calculated amount based on the subsidy rate exceeds the maximum limit of 200,000 yen, the amount provided will be “up to the maximum limit.”
For more details, please see here!
Child-Rearing Green Housing Support Project
Eligible Applicants
This program targets child-rearing households (households with children under 18) and young couple households, focusing on those who are building or purchasing homes with high energy efficiency or renovating existing homes for energy conservation. For new construction, the builder or purchaser is eligible, while for renovations, the contractor placing the order is eligible for the subsidy.
Requirements
For new residential buildings, it is necessary to meet high energy-saving performance standards set by the government, such as ZEH standards or higher. In the case of renovations, it is required to carry out construction that improves the energy-saving performance of the house, such as insulation renovations or the introduction of energy-saving equipment. In both cases, it is necessary to contract with a registered business and carry out the construction within the specified period.
Subsidy Upper Limit
For new constructions, the maximum amount per unit is between 400,000 yen and 1,600,000 yen, depending on the performance category of the house, while for renovations, the upper limit is between 400,000 yen and 600,000 yen per unit, depending on the content of the work. In either case, even if multiple constructions are carried out, it is not possible to receive subsidies exceeding this upper limit.
Subsidy Rate
This program does not provide a subsidy based on a certain percentage of the construction cost; instead, a predetermined “fixed subsidy” is granted based on the content of the work and performance category. Therefore, in effect, the government covers part of the construction cost.

Advanced Window Renovation Project
Eligible Participants
Owners of existing homes (single-family homes and apartment buildings) who are carrying out insulation renovation work on windows and openings are eligible. The actual subsidy application process is carried out by registered “window renovation contractors” with the government, and the granted subsidies are fully refunded to the homeowners through discounts on construction costs.
Requirements
Eligible renovations include window improvements aimed at enhancing insulation performance, such as the installation of interior windows, replacement of exterior windows, and glass replacement in existing homes. It is necessary to use products that meet the insulation performance standards set by the government and to enter into a construction contract with a registered window renovation contractor. Additionally, the total subsidy amount must be 50,000 yen or more, and construction must start and be completed within the specified construction period.
Subsidy Upper Limit
The upper limit for subsidies is 2,000,000 yen per unit. Even if multiple windows are renovated, the total subsidy that can be received for the same house is limited to this upper limit.
Subsidy Rate
The subsidy rate is approximately equivalent to half of the construction costs. The actual subsidy amount is set at a fixed rate based on the type of window (interior window, exterior window, glass), size, and insulation performance category, resulting in a total that is approximately 50% of the construction costs.

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 tile: Kunishiro tile 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. Seven S is a clear waterproofing material for tile exterior walls, and while it is somewhat expensive, its high waterproofing capability makes it a recommended choice when leaks are occurring from multiple areas of the exterior. |
How to Choose a Large-Scale Renovation Contractor
There are many large-scale renovation contractors that serve Hadano City, and it can be confusing to decide which one to choose.
Therefore, 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 warranties and aftercare services
● Obtain estimates from multiple contractors (at least three)
● Verify if they manage their own projects
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 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 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 sharing information about laundry through bulletin boards and other means.
Kakeru Koumuten Co., Ltd. specializes in exterior construction, 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 demonstrate confidence in their work, which can serve as a criterion for selecting a contractor!
Warranty periods vary by contractor and type of work, but generally range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Moreover, some contractors offer after-sales services in addition to warranties, so be sure to check whether the contractor you are considering has warranties and after-sales services.
At Kakeru Koumuten Co., Ltd., we send out annual direct mail for after-sales maintenance, allowing for yearly inspections.
We also 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, warranties, and after-sales services may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, 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 substrate repair 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!
Especially regarding substrate repair work, which can be difficult to assess from appearance, be sure to check 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 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 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 drawbacks of contractors that outsource is that if any trouble occurs during construction, their response may be delayed.
It is safer to avoid companies that do not have direct meetings with customers managing 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!
