Guidelines for Interior Renovation
1. Wallpaper (Cross) Renovation
- 10 to 15 years
Wallpaper deteriorates depending on usage frequency and environment, so it is advisable to consider replacement every 10 to 15 years. Especially in areas with high humidity, such as kitchens and bathrooms, or in places with strong sunlight, fading, dirt, and mold growth may occur more quickly.
2. Flooring Renovation
- 10 to 15 years
Flooring can show signs of wear and scratches, so it is good to consider renovation every 10 to 15 years. Particularly in households that frequently move heavy furniture or have pets, wear and tear can progress more quickly. It is important to not only repair the surface of the flooring but also check the condition underneath and renovate as necessary.
3. Toilet Renovation
- 10 to 15 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Kitchens and bathrooms are used frequently, so the equipment may become outdated or deteriorate. In particular, sinks, stoves, and bathtubs can deteriorate quickly, so it is advisable to consider renovation every 10 to 20 years. Additionally, replacing with the latest equipment can improve usability and energy efficiency.
5. Lighting and Outlet Renovation
- 10 to 20 years
Replacing lighting fixtures and outlets is generally done when they look old or their functionality decreases. Incorporating the latest LED lighting and smart features can enhance convenience and energy efficiency.
6. Door and Window Renovation
- 15 to 20 years
Consider door and window renovation when you notice difficulty in opening and closing or a decrease in insulation performance. Particularly, replacing with insulation materials or double-glazed windows can significantly improve energy efficiency.
7. Air Conditioning and Heating Equipment Renovation
- 10 to 15 years
Air conditioning and heating devices may lose performance after about 10 years, so it is recommended to replace or maintain them every 10 to 15 years. Air conditioners, in particular, tend to accumulate dirt in filters and interiors, leading to decreased efficiency.
8. Overall Renovation (Complete Interior Update)
- 20 to 30 years
Renovating the entire interior of the house (walls, flooring, ceilings, equipment, etc.) is typically done every 20 to 30 years.
Points to Consider When Deciding on Renovation Timing
Changes in Lifestyle
It is good to create opportunities to review the interior according to changes in family structure or work and hobbies.
Equipment or Functionality Issues
For example, if heating and cooling are less effective, or if the usability of the kitchen or bathroom has declined, these are signs that it may be time for renovation.
Appearance and Comfort
If dirt, scratches, or fading become noticeable, or if you feel that the interior has become outdated, it may be time to consider renovation.
