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

Fuchu City, Tokyo, is a historic town that prospered as the front town of Okunitama Shrine, with a residential area blessed by the history of the Keio Line and Musashi-Kokufu, as well as the nature of the Tama River. It is popular for its excellent commercial and transportation convenience, making it easy to live in.

Single-family homes and housing complexes developed during the Showa era are now entering a period of generational change, reaching 40 to 50 years old. This is why the option of “buying used single-family homes or housing complexes and renovating (renovating) them to suit one’s lifestyle” is expanding in Fuchu 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 in renovated or refurbished used homes. 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. Additionally, by changing the layout and refreshing the interiors, you can finish the home to suit your family’s lifestyle while keeping costs lower than new construction.

Reason 2 To Increase Asset Value for Sale

More people are purchasing and renovating used properties with the intention of selling them. Used homes are often valued low as they are, but renovations can improve their appearance and performance, thereby increasing their value as properties.

Reason 3 To Utilize as Investment or Business

When purchasing for investment or business purposes, renovations are essential. By transforming them 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, they may also qualify for subsidies or tax incentives, leading to an increase in the number of people utilizing vacant houses for business.

03Points to Consider 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 with peace of mind. Since used properties have had 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 the 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 confirm which parts are deteriorating and to what extent beforehand. 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 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. Furthermore, 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. Tax deductions include the “housing loan tax deduction” when using a housing loan, and there are systems that allow for deductions on certain costs even with personal funds. These can sometimes be used in combination, so it is crucial to check in advance and utilize them strategically as a key to 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 vary significantly based on the extent of damage and the scope of work. First, please understand the approximate costs by area as a guideline for your financial planning (the table below provides general estimates for typical single-family homes. 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 and Infrastructure

5. Waterproofing and Earthquake 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 depending 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 Fuchu City

There are many renovation companies that serve Fuchu 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 ample 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 the posts. Google reviews are particularly useful, but do not make a decision based solely on reviews; assess them comprehensively along with construction achievements, estimates, and warranty details.

2. Check for Warranties and After-Sales Maintenance

When selecting 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, but typically ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also offer after-sales services in addition to warranties, so be sure to check for those as well.

Kakeru Koumuten Co., Ltd. provides a guarantee for exterior renovations and sealing work. We also conduct aftercare maintenance and send out annual notification DM to ensure annual inspections are possible.

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, guarantees, aftercare services, and prices can vary significantly. Having multiple estimates makes price negotiations easier.

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

4. Confirm whether the company performs renovations in-house

At Kakeru Koumuten, we conduct detailed hearings and investigations regarding the existing “condition,” “location,” “base materials,” “desired durability,” and “design,” to propose the optimal plan. While there is nothing inherently wrong with a system where partner companies perform the work, it is important to confirm whether the contracting company understands the work details and has clear responsibility for quality control and guarantees. If the work is done in-house, it is easier to coordinate with the site, making it quicker to respond in case of any issues.

5. Check if they offer color simulations and perspective drawings

Choosing colors and visualizing the outcome after construction can be challenging for both exterior and interior work. Having simulations can reduce the risk of mistakes like “it turned out differently than I imagined.” Since it is difficult to redo once the work is done, it is advisable to choose a company that can provide flexible simulations.

One reason is that Kakeru Koumuten Co., Ltd. serves Fuchu City, but

We store roofing materials and paints. By placing large orders at once, we can procure materials at a lower cost, and since we always have stock available, we can respond quickly in emergencies. We also have various tools ready for different types of construction, including compressors and cleaning machines.

In-house waste separation

In exterior renovations, various waste materials such as paint, wood, and metal are generated. While many contractors dispose of them all together, our company significantly reduces waste disposal costs by separating and recycling waste materials.

Exterior renovation dedicated showroom

In the 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 insulation properties using color simulations and heat insulation testing equipment. The showroom is a 3-minute walk from Eda Station in Aoba-ku, Yokohama, and is accessible from Tokyo as well.

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 delivering high-quality renovations. Since one representative handles everything from the estimate to the completion of the work, there are no changes in the sales or construction management teams, allowing for smooth communication. From temporary scaffolding installation to exterior wall painting and roof renovations, all work 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.

4. Warranty and Aftercare

Exterior wall painting and joint sealing work come with a warranty. Aftercare is available annually, and we send out notification DM each year. If you have concerns about the warranty, please click the image above for more information.

5. Flexible and Prompt Response

We are equipped to handle various exterior troubles and situations. If you cannot access the roof due to height, we can respond with a drone. We also use a thermal imaging camera for leak investigations. We respond according to our customers’ wishes and also accept emergency measures for sudden leaks from exterior walls.

6. Human Resource Development

We create various models to enhance skills and conduct practical training. Since the construction methods and materials used for exterior renovations differ based on the existing materials and shapes, we conduct regular technical training to ensure that each staff member can respond to various sites.
