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

Chigasaki City is a popular city in Shonan facing Sagami Bay, symbolized by Southern Beach and Eboshiiwa, known for its coastal charm. The area features flat and livable terrain with a focus on single-family homes.

Single-family residential areas developed during the Showa era are now entering a generation change period, with many homes being around 40 to 50 years old, and locations near the sea face challenges related to salt damage. This is why the option of “buying a used single-family home and renovating (or renovating) it to suit one’s lifestyle” is expanding in Chigasaki City.

02Reasons for Renovating Vacant Houses and Used Properties

In recent years, the Japanese housing market has expanded options not only for new builds but also for renovating 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 updating the facilities and interiors, you can create a comfortable living environment. Additionally, by changing the layout and refreshing the interior, you can finish your 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 houses are often valued low as they are, but renovations can enhance their appearance and performance, increasing their value as properties.

Reason 3 To Utilize as Investment or Business

For purchases made 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 construction, and depending on the purpose and conditions, there may be subsidies or tax incentives available, leading to an increase in 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 the renovation. 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 have deteriorated and to what extent beforehand. Since the property has been occupied by someone else, internal damage is often not apparent without investigation. Conduct a current condition survey before starting work to identify hidden deterioration.

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 homes 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 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 mortgage, and there are systems where part of the costs can be deducted for certain works even with personal funds. These can sometimes be used in combination, so it is essential to check in advance and plan to utilize them strategically for a successful renovation (for the latest information, see this subsidy section).

04Cost Estimates for Renovating Vacant Houses and Used Properties

The renovation costs for used properties and vacant houses vary significantly depending on the extent of damage and the scope of work. First, please understand the approximate costs by area to use as a guideline for your financial planning (the table below provides general estimates for 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-related Equipment

4. Equipment & Infrastructure

5. Waterproofing & 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 Remodeling Contractor for Used Properties and Vacant Houses in Chigasaki

There are many remodeling companies that serve Chigasaki, and it can be confusing to decide which one to choose. When requesting a remodel, be sure to check the following five points.

1. Rich experience in remodeling work

Many remodeling 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, providing peace of mind. If you have concerns, choose a contractor with extensive experience.

Google and review sites can be helpful references. It is important to check the content of low ratings, the company’s responses, and the timing of the 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 typically ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also offer aftercare services, so be sure to check for those 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, making annual inspections possible.

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

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

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.” 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 company conducts renovations in-house

At Kakeru Koumuten Co., Ltd., we conduct detailed hearings and investigations regarding the existing “condition,” “location,” “materials,” “desired durability,” and “design” to propose the optimal plan. While there is nothing inherently wrong with the system where partner companies perform the construction, it is essential to confirm whether the contracted company understands the construction details and has clearly defined responsibilities for quality control and guarantees. If we handle the construction ourselves, it becomes easier to coordinate with the site, allowing for quick responses in case of any issues.

5. Do they support color simulations and perspective drawings?

Choosing colors and visualizing the image after construction can be challenging for both exterior and interior projects. With simulations, you can reduce the risk of mistakes like “it looks 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 renovations of used houses in Chigasaki City

One reason is that “Kakeru Koumuten also serves Chigasaki City,” but
“our unique approach to renovating vacant and used properties that cannot be imitated by other companies”
has received high praise from many customers.

At Kakeru Koumuten, we have established warehouses and material storage areas to provide high-quality renovations at low costs. We have five bases for material storage and showrooms located within Yokohama City.

In-house ownership of scaffolding materials

For exterior renovations, we can construct temporary scaffolding using our own scaffolding materials and in-house scaffolding team. By not outsourcing, this leads to cost reductions in scaffolding work. We own scaffolding materials for approximately 50 single-family homes.

Materials stored in our large in-house 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 waste collectively, our company separates and recycles waste, significantly reducing waste disposal costs.

Exterior renovation dedicated showroom

In our showroom, you can not only have meetings but also check the actual paint colors and a wide variety of catalogs. You can also confirm heat resistance using color simulation and heat-resistant paint testing equipment. 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 setup 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 construction industry licenses and permits for industrial waste collection and transportation. 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 every year, and we send out notification DM annually. If you are concerned about the warranty, please click on the image above to check.

5. Flexible and Prompt Response

We are equipped to handle various exterior troubles and situations. Even if you cannot access the roof at high altitudes, 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 the construction methods and materials used for exterior renovations differ based on existing materials and shapes, we regularly conduct technical improvement training to ensure each staff member can handle various sites.
