Interior Renovation Guidelines
1. Wallpaper Renovation
- 10 to 15 years
Wallpaper deteriorates over time depending on usage and environment, so it is advisable to consider replacement every 10 to 15 years. In particular, areas with high humidity such as kitchens and bathrooms, or areas with strong sunlight, may experience fading, staining, and mold growth more quickly.
2. Flooring Renovation
- 10 to 15 years
Flooring becomes noticeable for wear and scratches, so it is good to consider renovation every 10 to 15 years. This is especially true for homes where heavy furniture is frequently moved or where pets are present, as damage can progress more quickly. It is important not only to repair the surface of the flooring but also to check the condition beneath the floor and carry out renovations as necessary.
3. Toilet Renovation
- 10 years
The general guideline for toilet replacement is about every 10 years.
4. Kitchen and Bathroom Renovation
- 10 to 20 years
Kitchens and bathrooms are used frequently, so equipment may become outdated or deteriorate. In particular, the deterioration of sinks, stoves, and bathtubs can occur quickly, so it is advisable to consider renovation every 10 to 20 years. Additionally, upgrading to the latest equipment can improve usability and energy efficiency.
5. Lighting and Outlet Renovation
- 10 to 20 years
Replacing lighting fixtures and outlets is typically done when they look outdated or their functionality declines. Incorporating the latest LED lighting and smart features can enhance convenience and energy efficiency.
6. Door and Window Renovation
- 15 to 20 years
Door and window renovations are considered when there are difficulties in opening and closing or when insulation performance declines. In particular, replacing insulation materials or installing double-glazed windows can significantly improve energy efficiency.
7. Air Conditioning and Heating Equipment Renovation
- 10 to 15 years
Air conditioning and heating equipment may experience a decline in performance after about 10 years, so it is recommended to replace or maintain them every 10 to 15 years. In particular, air conditioners tend to accumulate dirt in the filters and inside, which reduces efficiency.
8. Overall Renovation (Complete Interior Update)
- 20 to 30 years
Renovating the entire interior of a house (walls, flooring, ceilings, fixtures, etc.) is typically done once every 20 to 30 years.
Points to Consider When Deciding on Renovation Timing
Changes in Lifestyle
It is good to create opportunities to reassess the interior in line with changes in family structure or work and hobbies.
Malfunctions in Equipment or Functions
For example, if heating and cooling have become ineffective, or if the kitchen or bathroom has become inconvenient to use, these signs indicate that it may be time for a renovation.
Appearance and Comfort
If dirt, scratches, or fading have become noticeable, or if you feel that the interior has become outdated, it is a good time to consider renovation.
