For those considering renovations of used properties and vacant houses in Miura City

I bought a used property, but I’m not sure if the renovation estimate I received is reasonable

This is my first full renovation, and I’m worried about making mistakes

I want to make the most of subsidies and grants

For such concerns, Kakeru Koumuten Co., Ltd., which has numerous achievements in Miura City, will clearly explain the key points for a successful renovation.

Obtain estimates from at least 3 companies!

01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Miura City

Miura City is located at the southernmost tip of the Miura Peninsula, known for its tuna from Misaki Port and Miura daikon, a town of sea and agriculture. The Keikyu Line and National Route 134 run through the area, blessed with coastal scenery and rich nature.

Old wooden houses near the coast and fishing ports are at a stage where they require seismic, insulation, and salt damage considerations, and are also gaining attention as a place for relocation and dual residences. This is why the option of “buying a used detached house and renovating (renovating) it to suit your lifestyle” is expanding in Miura City.

02Reasons for Renovating Vacant Houses and Used Properties

In recent years, the Japanese housing market has expanded options not only for new constructions but also for utilizing renovated used properties. There is a growing interest in living by purchasing and renovating used houses. Here, we explain the typical reasons for renovating vacant houses and used properties.

Reason 1 To Live Comfortably as Your Own Home

The most common reason for purchasing and renovating a used property is “to live comfortably.” Older houses often have issues with the roof, exterior walls, and plumbing, making them difficult to live in as they are. By renovating and upgrading the facilities and interiors, you can create a comfortable living environment. Furthermore, by changing the layout and refreshing the interior, you can achieve a home that suits your family’s lifestyle while keeping costs lower than new construction.

Reason 2 To Increase Asset Value for Resale

More people are purchasing and renovating used properties with the intention of resale. Used houses are often evaluated as having low asset value in their current state, but renovations can enhance both appearance and performance, increasing the property’s value.

Reason 3 To Utilize as an Investment or Business

For purchases intended for investment or business, renovations are essential. By transforming properties into stylish rentals or share houses, you can differentiate them from other properties, and depending on the location and planning, you can also expect improved profitability. Initial costs can be lower than new constructions, and depending on the purpose and conditions, there may also be subsidies or tax incentives, leading to an increase in the number of people utilizing vacant houses for business.

03Points to Note When Renovating Vacant Houses and Used Properties

Point 1 Choose a Reliable Construction Company

First and foremost, it is essential to select a contractor you can trust to handle your renovation. For used properties, since there were previous occupants, the internal structure and condition are often not clear until you actually see them. Choose a contractor who can carry out the work thoroughly according to your wishes, the structure of your house, and the surrounding environment, and who also provides aftercare following the construction.

Point 2 Always Check the Deterioration of the Building

For used properties and vacant houses, it is crucial to check which parts are deteriorating and to what extent in advance. Since there have been other occupants, the internal damage is often not apparent without investigation. Make sure to understand any hidden deterioration through a current condition survey before starting the work.

Point 3 Review Earthquake Resistance and Insulation Performance

Particularly important in the renovation of used and vacant houses is the review of earthquake resistance and insulation. The earthquake resistance standards were significantly revised in 1981, and houses built before that may not meet current standards. Additionally, in 2000, regulations regarding joints and foundations were strengthened, making older buildings more likely to lack earthquake resistance. Check the condition of the building before starting work and be sure to check the earthquake resistance and insulation.

Point 4 Check Subsidy Programs and Renovation Tax Deductions

To keep construction costs down, it is important to check for subsidies and renovation tax deductions. Subsidies are provided by the national and local governments, supporting part of the costs for earthquake retrofitting, energy-saving construction, and barrier-free renovations. There are tax deductions available for “housing loan tax deductions” when using a housing loan, and certain works can also qualify for deductions even with personal funds. These can sometimes be used in combination, so it’s essential to check in advance and plan to utilize them strategically for a successful renovation (for the latest information, see this subsidy section).

04 Cost Estimates for Renovating Vacant Houses and Used Properties

The renovation costs for used properties and vacant houses can vary significantly depending on the extent of damage and the scope of work. First, please familiarize yourself with the approximate costs by area to serve as a guideline for your financial planning (the table below provides general estimates for typical detached houses. The interior is based on a room of about 6 tatami mats, and the exterior is based on the indicated scope of work. Actual estimates will be provided after a site survey).

1. Roof and Exterior Walls

2. Interior (Interior Finishing)

3. Water Facilities

4. Equipment & Infrastructure

5. Waterproofing & Seismic Resistance

6. Exterior Works

* The above are general estimates. Costs may vary depending on the presence of scaffolding, the condition, grade, and area of the building. Waterproofing of rooftops and updates to plumbing and wiring for the entire house may exceed the above estimates based on area and method. Please confirm the exact costs through a free on-site survey and estimate.

07How to Choose a Renovation Contractor for Used Properties and Vacant Houses in Miura City

There are many renovation companies available in Miura City, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following 5 points.

1. Experience in Renovation Work

Many renovation contractors publish their construction achievements on their websites. If a contractor provides detailed explanations of the process with photos, it makes it easier to visualize the outcome after the request, giving you peace of mind. If you have concerns, choose a contractor with rich experience.

Google and review sites can also be helpful. It is important to check the content of low ratings, the company’s responses, and the timing of posts. In particular, Google reviews are useful, but do not make your decision based solely on reviews; consider the construction results, estimates, and warranty details for a comprehensive judgment.

2. Confirm the presence of warranties and aftercare services

When choosing a contractor, be sure to check for warranties. If repairs are needed within the warranty period, they may be done for free. The duration varies by contractor and paint type, but generally ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also offer aftercare services separate from warranties, so be sure to check that as well.

Kakeru Koumuten Co., Ltd. provides warranties for exterior renovations and sealing work. We also conduct aftercare services and send out annual notification DM, allowing for annual inspections.

3. Obtain estimates from multiple contractors (at least 3 companies)

When requesting renovations, be sure to obtain estimates from multiple contractors. Even for the same work, warranties, aftercare services, and prices can vary significantly. Having multiple estimates makes it easier to negotiate prices.

When comparing estimates, it is important to look at not just the costs, but also the “items in the estimate,” “check the undercoat materials, sealing materials, and paint for auxiliary parts,” and “confirm the process” in detail. Lowering the rank of auxiliary parts or skipping steps can reduce costs, so it is crucial to not judge solely based on price.

4. Confirm whether the work is done in-house

Kakeru Koumuten Co., Ltd. conducts detailed hearings and investigations regarding the existing “condition,” “location,” “materials,” “desired durability,” and “design” to propose the most suitable plan. While there is nothing inherently wrong with the system where partner companies carry out the construction, it is important to confirm whether the contracted company understands the construction details and clearly defines the responsibilities for quality control and guarantees. If the construction is done in-house, it becomes easier to coordinate with the site, allowing for quick responses in case of any troubles.

5. Do they support color simulations and perspective drawings?

Choosing colors and envisioning the appearance after construction can be challenging for both exterior and interior projects. With simulations, you can reduce the risk of mistakes like “it looked different from what I imagined.” Since it is difficult to redo once construction is completed, it is advisable to choose a company that can provide flexible simulations.

08Reasons why Kakeru Koumuten is chosen for remodeling used houses in Miura City

One reason is that “Kakeru Koumuten also serves Miura City,” but
“Our unique approach to remodeling vacant houses and used properties that cannot be replicated by other companies”
has received high praise from many customers.

1. Equipment specialized for in-house remodeling

Kakeru Koumuten has established warehouses and material storage areas to provide high quality at low cost for remodeling projects. We have 5 bases for material storage and showrooms located within Yokohama City.

In-house scaffolding materials

For exterior renovations, temporary scaffolding is essential, and we can construct it using our own scaffolding materials and in-house scaffolding team. By not outsourcing, this leads to cost savings on scaffolding work. We own scaffolding materials for approximately 50 houses.

Materials stored in our large warehouse

We store roofing materials and paints. By placing large orders at once, we can procure materials at lower prices, and since we always have stock available, we can respond quickly in emergencies. We are also equipped with various tools that can handle different types of construction, such as compressors and cleaning machines.

In-house waste separation

In exterior renovations, various types of waste such as paint, wood, and metal are generated. While many contractors dispose of them all together, we separate and recycle waste, significantly reducing waste disposal costs.

Showroom dedicated to exterior renovations

In our showroom, you can not only have meetings but also check the actual paint colors and a wide range of catalogs. You can also confirm heat resistance using a heat-resistant paint testing machine and color simulation. The showroom is a 3-minute walk from Eda Station in Aoba-ku, Yokohama.

2. Complete In-House Construction

A major strength of Kakeru Koumuten Co., Ltd. is our complete in-house construction. By maintaining a consistent system from inquiry to project completion, we can keep costs down while providing high-quality renovations. A single representative handles everything from the estimate to project completion, ensuring smooth communication without changes in sales or construction management. All work, from temporary scaffolding installation to exterior wall painting and roof renovations, is carried out by our own skilled craftsmen. We are confident in our plans and costs, so we welcome competitive estimates.

3. Various Permits and Skilled Workers

We have obtained permits for the construction industry and for the collection and transportation of industrial waste. We also have nationally certified sheet metal workers and painting specialists on staff, ensuring confidence in our construction techniques. We are capable of handling large-scale painting projects for factories and apartment complexes as well.

4. Warranty and Aftercare

Exterior painting and joint sealing work come with a warranty. Aftercare is available annually, and we send out notification DM every year. If you are concerned about the warranty, please click on the image above for confirmation.

5. Flexible and Prompt Response

We are equipped to handle various exterior troubles and situations. Even if you cannot access the roof at high places, we can respond using a drone. For leak investigations, we also use a thermal imaging camera. We respond according to our customers’ wishes and also accept emergency measures for sudden leaks from the exterior walls only.

6. Human Resource Development

We create various models for skill enhancement and conduct practical training. Since exterior renovations differ in construction methods and materials based on existing materials and shapes, we regularly conduct technical improvement education to ensure each staff member can handle various sites.

7. Flexible Simulations for Both Exterior and Interior!

Kakeru Koumuten is dedicated to helping you choose colors and designs for your important building renovations, both exterior and interior, to ensure your satisfaction.

7-1. Exterior Renovation Simulation

We can create color simulations for exterior wall painting, as well as simulations for metal siding and roof overlays. We can create simulations from actual photos of your building and propose several patterns with our recommended color combinations. We also accommodate “test painting” and “arranging paint boards” to confirm the actual color tones.

7-2. Interior Renovation Simulation

We also support simulations and perspective drawings for interior renovations. Based on your preferred image, such as a modern style, we will propose recommended simulations. We create realistic perspectives from actual floor plans.

8. We also handle solar panel and storage battery installation work!

More customers are introducing solar equipment with substantial subsidies in line with renovations of used properties. Kakeru Koumuten Co., Ltd. also handles solar equipment installation and proposes solar panels tailored to the shape of your roof. We can also accept requests for estimates and power generation simulations only.
