“Subsidies and costs available for large-scale repairs in Miura City”
“How to choose a large-scale repair contractor in Miura City”
“Why Kakeru Koumuten is chosen in Miura City”
These topics will definitely be useful for owners and management associations
considering repairs or exterior renovations for 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 3 estimates from large-scale repair companies that cover Miura City!
Reasons why Kakeru Koumuten is chosen for large-scale repairs in Miura City
One reason we are entrusted with large-scale repairs in Miura City is that
“Kakeru Koumuten has a base in Kanagawa Prefecture,” 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” for exterior renovations of apartments, condominiums, and commercial facilities in Miura 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 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 purchase materials at a lower cost!
Additionally, we always have stock available, enabling 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.
While most contractors dispose of these materials together, by sorting and recycling waste materials, significant cost reductions in 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’s major strengths is its in-house management and construction.
By managing everything from inquiries to project completion in a consistent system, Kakeru Koumuten can provide high-quality large-scale repairs while keeping costs down.
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 sales or construction management, smooth communication is possible.
We can fully handle everything from the installation of temporary scaffolding to exterior wall painting, substrate repair, waterproofing work, and tile repairs with our own staff!
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 specialists on staff, so we are confident 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 pre-investigations.
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!
We will promptly respond to urgent requests or 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 for each staff member to ensure they can respond effectively.
We also educate on points to be careful of 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 the construction schedule and announcements!
Additionally, we thoroughly educate entrants on manners to minimize any inconvenience to residents and neighbors.
8. Strict Quality Control
Each stage of the 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 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 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 an image change, 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 perform test painting on your exterior walls.
By conducting a test painting, you can confirm the actual color and gloss!
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 such as cornices and louvers
・Simulation for roof painting and roof replacement work is also possible
The risk of failure in image change through exterior renovation simulation can be minimized!
We hope that renovating the appearance of your apartment or condominium will help increase occupancy rates.

Kanagawa Prefecture Existing Housing Energy Efficiency Renovation Subsidy
Eligible Applicants
The eligible applicants for this subsidy are owners of existing homes located in Kanagawa Prefecture who reside in those homes on a daily basis. The eligible homes must be residences where the owner themselves lives, regardless of whether they are single-family homes or condominiums.
Eligible Work and Conditions
To receive the subsidy, the following requirements must be met. First, the renovation work must target existing homes in the prefecture and utilize products with insulation performance specified by the national government, such as windows, glass, and insulation materials. Additionally, the home must ensure seismic performance, and a pre-application must be submitted before starting the work, with work commencing only after receiving a grant decision. Eligible renovation work includes insulation improvements for windows, floors, walls, and ceilings.
Subsidy Amount
The maximum amount for this subsidy is 200,000 yen per residence. This is the total subsidy provided for implementing eligible energy efficiency renovation work, 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 of 200,000 yen, the amount granted will be “up to the maximum amount.”
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 couples, focusing on the construction or purchase of energy-efficient homes, or energy-efficient renovations of existing homes. For new constructions, the builder or purchaser is eligible, while for renovations, the contractor who orders the work is eligible for the subsidy.
Requirements
For new residential buildings, it is necessary to meet high energy efficiency standards set by the government, such as ZEH level or higher. In the case of renovations, it is a condition to carry out construction that improves the energy efficiency of the house, such as insulation renovations and the introduction of energy-saving equipment. In both cases, it is necessary to contract with a registered contractor and carry out the construction within the specified period.
Subsidy Limit
For new constructions, the maximum subsidy per unit is between 400,000 yen and 1,600,000 yen, depending on the performance category of the house, while for renovations, the maximum subsidy per unit is between 400,000 yen and 600,000 yen, depending on the nature of the work. In either case, even if multiple constructions are carried out, it is not possible to receive subsidies exceeding this 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 provided for each type of work and performance category. Therefore, in effect, the government bears part of the construction cost.

Advanced Window Renovation Project
Eligible Participants
Owners of existing houses (single-family homes and apartment buildings) who are conducting insulation renovation work on windows and openings are eligible. The actual application process for the subsidy is carried out by registered “window renovation contractors” recognized by the government, and the granted subsidies are fully refunded to the homeowners through discounts on construction costs.
Requirements
The eligible renovations include window improvements aimed at enhancing insulation performance, such as the installation of interior windows, replacement of exterior windows, and glass replacements 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 the work must start and be completed within the specified construction period.
Subsidy Limit
The maximum subsidy 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 maximum amount.
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 Repair Work on a Mixed-Use Building
| Construction Details |
| Partial replacement of damaged tiles Painting of auxiliary 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 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. 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 material 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 cover Miura City, and it can be confusing to decide which one to choose.
Therefore, when requesting renovations for apartments, condominiums, or 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 remodeling project achievements.
Additionally, if they provide detailed explanations of repair contents 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 one with extensive experience in large-scale renovations.
It is also effective to refer to reviews of skylight installation contractors on Google and review sites!
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 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 free of charge, 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 the nature of the 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 separate 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 annual 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, make sure to 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 can vary 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 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 to make 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 base repair work, since it can be difficult to identify issues from the exterior, be sure to confirm whether the repair method is appropriate for the condition of the base!
Check if it is managed in-house
Large-scale renovation work includes various tasks 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 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 the work 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 staff will manage the construction!
