Ceiling Installation Work Procedure in Shinagawa Ward, Tokyo

1. Installing the Subframe

We will install the substrate materials! We will install the subframe lumber and the sheathing board to prepare for the installation of insulation and boards!

2. Laying Insulation

By adding insulation, we make it difficult for the heat and cold from outside to transfer indoors, reducing the occurrence of condensation and mold. This also leads to improved heating and cooling efficiency and better indoor environment.

3. Installing Gypsum Board and Applying Joint Compound

We will install the gypsum board and apply the joint compound! We will install the gypsum board so that wallpaper can be applied, and apply the compound to eliminate any unevenness.

What is Gypsum Board?

It is a board made from a white powder that hardens when mixed with water and becomes hard when dried.
It also has fire-resistant properties and is commonly used as a material for walls and ceilings.

4. Wallpaper Installation

We will install the wallpaper! We will adjust the joints with the existing ceiling and walls to ensure that repair marks are less noticeable.

After Skylight Sealing Work

By sealing the skylight and adding insulation, the insulation performance has improved!

Interior Renovation Guidelines

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. In particular, in areas with high humidity such as kitchens and bathrooms, or in places with strong sunlight, fading, dirt, and mold may occur 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. Especially in households that frequently move heavy furniture or have pets, damage progresses more quickly. It is important not only to repair the surface of the flooring but also to check the condition underneath and carry out renovations as necessary.

3. Toilet Renovation

  • 10 to 15 years
    The general guideline for replacing a toilet is about 10 years.

4. Kitchen and Bathroom Renovation

  • 10 to 20 years
    Due to high usage, kitchens and bathrooms may become outdated or deteriorate. In particular, the wear and tear of sinks, stoves, and bathtubs can occur quickly, so it is advisable to consider renovations 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
    It is common to replace lighting fixtures and outlets when they look outdated or their functionality declines. Incorporating the latest LED lighting and smart features can enhance convenience and energy savings.

6. Door and Window Renovation

  • 15 to 20 years
    Consider renovating doors and windows when you notice difficulty in opening and closing or a decrease in insulation performance. Particularly, 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 units may experience a decline in 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 internal components, leading to reduced efficiency.

8. Overall Renovation (Complete Interior Update)

  • 20 to 30 years
    Renovating the entire interior of a house (walls, floors, ceilings, fixtures, etc.) is typically done every 20 to 30 years.

Points to Consider When Deciding on Renovation Timing

Changes in Lifestyle

It is a good idea to create opportunities to reassess the interior in line with changes in family structure, work, or hobbies.

Malfunctions in Equipment or Functions

For example, if heating and cooling have become ineffective or if the usability of the kitchen or bathroom has declined, these signs indicate 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 is time to consider renovation.
