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

Atsugi City is a central city in the prefecture that developed around Hon-Atsugi, serving as the gateway to the Oyama and Tanzawa mountains. It is a transportation hub where the Odakyu Line, Tomei Expressway, and Ken-O Expressway intersect, with residential areas blessed with the waters and greenery of the Sagami River.

The residential areas from the Showa era surrounding the city center and suburbs are entering a generational change period, reaching 40 to 50 years of age. This is why in Atsugi City, the option of “buying a used house and renovating it to fit your lifestyle” is expanding.

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. Interest in purchasing used homes and renovating them for living is also increasing. 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 less livable as they are. By renovating and updating the facilities and interior, you can create a comfortable living environment. Additionally, by changing the layout and refreshing the interior, you can finish 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 homes are often evaluated at a low asset value as they are, but through renovation, their appearance and performance can be improved, thereby increasing their value as properties.

Reason 3 To utilize as an investment or business

When purchasing for investment or business purposes, renovation is essential. By transforming into a highly designed rental or share house, you can differentiate from other properties, and depending on the location and planning, you can also expect an increase in profitability. Compared to new construction, initial costs can be reduced, and depending on the use and conditions, there may also be eligibility for subsidies and tax incentives, leading to an increase in those utilizing vacant homes for business.

03Points to consider when renovating vacant homes or used properties

Point 1 Choose a reliable construction company

First and foremost, it is essential to choose 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 that can perform the work properly according to your wishes, the structure of the house, and the surrounding environment, and that also provides aftercare following the construction.

Point 2 Always check the deterioration of the building

For used properties and vacant homes, it is crucial to confirm which parts have deteriorated and to what extent in advance. Since there have been previous occupants, the internal damage is often not apparent without investigation. Conduct a current condition survey before starting work to identify any hidden deterioration.

Point 3 Review seismic and thermal performance

Particularly important in the renovation of used and vacant homes is the review of seismic and thermal performance. The seismic 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 seismic resistance. Check the condition of the building before starting work and be sure to check seismic and thermal performance.

Point 4 Check subsidy programs and renovation tax reductions

To keep construction costs down, it is important to check for subsidies and renovation tax reductions. Subsidies are provided by the national and local governments, supporting part of the costs for seismic retrofitting, energy-saving construction, and barrier-free renovations. Tax reductions include the “housing loan tax reduction” when using a housing loan, and there are systems where part of the costs can be deducted for certain works even with personal funds. These can sometimes be combined, so it is crucial to check in advance and plan to utilize them strategically as a key to successful renovation (for the latest information, see this subsidy section).

04Cost Estimates for Renovating Vacant and Used Properties

The renovation costs for used properties and vacant houses vary significantly depending on the level of damage and the scope of work. First, please understand the approximate costs by area to use as a guideline for your budget (the table below provides general estimates for typical detached houses. The interior is based on a single 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 for rooftops and updating plumbing and wiring for the entire house may exceed the above estimates depending on area and method. Please confirm the exact costs with a free on-site survey and estimate.

07How to Choose a Remodeling Contractor for Used Properties and Vacant Houses in Atsugi City

There are many remodeling companies that serve Atsugi City, and it can be confusing to decide which one to choose. When requesting a remodel, be sure to check the following 5 points.

1. They have extensive experience in remodeling work.

Many remodeling contractors publish their project achievements on their websites. If a contractor provides detailed explanations of the process with photos, it can help you 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 your decision based solely on reviews; consider the project achievements, estimates, and warranty details for a comprehensive assessment.

2. Confirm whether they offer 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 1 to 10 years is common (emergency repairs and partial repairs are often not covered). Some contractors also offer aftercare services in addition to warranties, so be sure to check that as well.

Kakeru Koumuten Co., Ltd. provides warranties for exterior remodeling and sealing work. We also conduct aftercare services and send out annual notification DM to ensure annual inspections are possible.

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

When requesting a renovation, be sure to obtain estimates from multiple contractors. Even with the same scope of work, warranties, after-sales service, and prices can vary significantly. Having multiple estimates makes it easier to negotiate prices.

When comparing estimates, not only the cost but also the “items in the estimate,” “check of undercoating materials, sealing materials, and paint for auxiliary parts,” and “confirmation of the process” should be carefully compared. Lowering the rank of auxiliary parts or skipping processes can reduce costs, so it is important not to judge solely by price.

4. Confirm whether the company performs renovations in-house

Kakeru Koumuten Co., Ltd. conducts detailed hearings and investigations regarding the existing “condition,” “location,” “substrate,” “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 contracted company understands the scope of work and clearly defines the responsibilities for quality control and warranty. If the work is done in-house, it is easier to coordinate with the site, and in the event of trouble, it can be addressed quickly.

5. Check if they offer color simulations and perspective drawings

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

08Reasons why Kakeru Koumuten is chosen for renovations of used houses in Atsugi City

One reason is that “Kakeru Koumuten also serves Atsugi City,” but
there are “initiatives in the renovation of vacant houses and used properties that cannot be imitated by other companies,”
which have received high praise from many customers.

1. Equipment Specialized for In-House Renovations

Kakeru Koumuten Co., Ltd. has organized warehouses and material storage to provide high-quality renovations at low cost. We have five bases for material storage and showrooms located in Yokohama City.

In-House Scaffolding Materials

We can construct temporary scaffolding, which is essential for exterior renovations, using our own scaffolding materials and in-house scaffolding team. By not outsourcing, this leads to cost reductions in scaffolding work. We have enough scaffolding materials for approximately 50 houses.

Storage of Materials 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 also have various tools ready to handle different types of work, 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 sorting and recycling waste materials.

Exterior Renovation 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 simulation and heat-resistant paint testing equipment. The showroom is a 3-minute walk from Eda Station in Aoba Ward, Yokohama City.

2. All Work Performed by Our Own Team

A major strength of Kakeru Koumuten is all work performed by our own team. By maintaining a consistent system from inquiry to project completion, we can keep costs down while providing high-quality renovations. Since one representative handles everything from the estimate to project completion, there is no change in the person responsible for sales and construction management, allowing for smooth communication. From the installation of temporary scaffolding to exterior wall painting and roof renovations, all work is carried out by our own craftsmen. We are confident in our plans and costs, so we welcome competitive estimates.

3. Various Permits Obtained & Skilled Workers on Staff

We have obtained permits for construction work and 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.

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 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 at height, we can respond using a drone. We also use a thermal imaging camera for leak investigations. We respond according to customer requests and also accept emergency measures for sudden leaks from exterior walls only.

6. Human Resource Development

To improve skills, we create various models and conduct practical training. Since exterior renovations vary in construction methods and materials based on existing materials and shapes, we regularly conduct technical improvement training to ensure each staff member can respond to various sites.

Kakeru Koumuten Co., Ltd. is dedicated to helping our customers choose colors and designs for both exterior and interior renovations, ensuring satisfaction with their important buildings.

7-1. Exterior Renovation Simulation

We offer color simulations for exterior wall painting, as well as simulations for metal siding and roof overlays. We can create simulations based on actual photos of your building and suggest several color patterns recommended by our company. We also accommodate “test painting” and “sample board arrangements” to confirm the actual color tones.

7-2. Interior Renovation Simulation

We also provide simulations and perspective drawings for interior renovations. We suggest recommended simulations based on your preferred style, such as modern designs. Realistic perspectives are created from actual floor plans.

8. Solar Panel and Storage Battery Installation Work Also Available!

With the renovation of used properties, more customers are introducing solar equipment that benefits from generous subsidies. Kakeru Koumuten also handles solar equipment installation and proposes solar panels tailored to the shape of your roof.
