Is the later maintenance cost of light steel villas high? What are the expenses?
The later maintenance cost of light steel villas is relatively not particularly high, but there are some necessary expenditure items, mainly including the following aspects:
Roof maintenance
Roof material inspection: Commonly used roofing materials for light steel villas, such as color steel plates and asphalt tiles, have a long service life, but may be damaged by natural factors such as wind, sun, and rain. Generally, the roof needs to be inspected every 2-3 years to check for leaks, broken tiles, rusted color steel plates, etc.
The inspection fee is generally around 500-1000 yuan each time. If some tiles need to be replaced or color steel plates need to be repaired, the material and labor costs depend on the actual situation. Replacing a small amount of asphalt tiles may cost 300-500 yuan, and repairing rusted parts of color steel plates may cost 200-800 yuan.
Roof waterproofing: The roof may need to be fully waterproofed every 5-8 years to ensure the waterproof performance of the roof. The cost of waterproofing is about 50-100 yuan per square meter. Taking a 200 square meter roof as an example, the total cost is about 10,000-20,000 yuan.
Wall maintenance
Exterior wall cleaning: The exterior walls of light steel villas are generally made of metal plates, decorative panels or paint, which are easy to absorb dust and stains and need to be cleaned regularly. Generally, the exterior walls are cleaned 1-2 times a year, and the cost of each cleaning is about 1,000-3,000 yuan depending on the size of the house.
Wall sealing inspection: The sealing strips and other components of the wall may age over time, resulting in a decrease in sealing performance, and need to be inspected and replaced regularly. Generally, it is inspected every 3-5 years, and problems are found and replaced in time. The cost of replacing the sealing strips is relatively low, about 20-50 yuan per meter. The cost of replacing the sealing strips of a villa may be 1,000-3,000 yuan.
Structural maintenance
Rust prevention: The main structure of the light steel villa is the light steel keel. Although it has been rust-proofed at the factory, it may still rust after long-term use. Generally, the light steel keel needs to be fully inspected and treated for rust prevention every 5-10 years, and the rusted parts need to be rusted and painted with anti-rust paint. The cost depends on the area and degree of rust, generally between 2000 and 5000 yuan.
Structural stability inspection: Every 10 years or so, it is recommended to ask a professional structural engineer to inspect the overall structure of the villa and evaluate the stability of the structure. The inspection fee is about 2000-3000 yuan. If problems are found in the structure, reinforcement and other treatments are required. The cost depends on the specific situation and may range from 5000 to 20000 yuan.
Thermal insulation system maintenance
Insulation material inspection: Although the service life of insulation materials is long, they may be damaged or displaced due to house settlement, external force damage, etc. Generally, the status of the insulation material is checked every 5-8 years. If there is any damage, it needs to be repaired or replaced in time. The cost of repairing or replacing the insulation material depends on the damaged area and the type of material, which may be 80-200 yuan per square meter.
Ventilation system maintenance: The ventilation system of the light steel villa, such as vents and exhaust fans, needs to be cleaned and maintained regularly to ensure good ventilation. Generally, it is maintained once a year, and the cost is about 500-1000 yuan.
In general, the annual maintenance cost of the light steel villa under normal use may be around 2000-5000 yuan. In the years when encountering major maintenance projects such as roof waterproofing treatment, structural inspection and reinforcement, the maintenance cost will increase, but the average annual cost is still relatively controllable.
