Warranty Period of Prefabricated Houses
The warranty period for prefabricated houses varies depending on the part of the house and the type of engineering, and is not a single fixed value. Details are as follows:
Foundation and main structure engineering:
The warranty period is the reasonable service life specified in the design documents. For example, staff from 'Sanzhiniu Cement Houses' clearly stated that the quality guarantee period for their cement prefabricated houses is 70 years. This period is usually consistent with the design life of the building, reflecting the long-term stability requirements of the foundation and main structure as the core supporting parts of the house. If the design documents do not specify a clear period, reference can be made to the minimum period standards in industry practices or relevant regulations.
Roof waterproofing engineering, bathrooms, rooms, and exterior walls with waterproofing requirements:
The warranty period for these parts is 5 years. Waterproofing engineering is a critical aspect prone to issues during house use. The 5-year period aims to cover common risks such as material aging and construction defects, ensuring that the house will not be affected by leakage in terms of structural safety or living experience under normal use conditions.
Heating and cooling systems:
The warranty period is 2 heating or cooling seasons. This regulation targets seasonally used systems, and 2 cycles can fully test the operational stability of the equipment under alternating hot and cold conditions, covering faults that may arise from installation defects or material quality issues.
Electrical pipelines, water supply and drainage pipelines, equipment installation, and decoration engineering:
The warranty period is 2 years. This type of engineering involves a large amount of concealed construction and functional components. The 2-year period can cover initial issues such as material aging and loose connections, while avoiding excessive maintenance responsibilities due to differences in user habits.
Other projects:
If not explicitly specified in the above categories, the warranty period is determined by contract between the construction unit and the construction contractor. Such agreements must comply with the minimum requirements of regulations such as the 'Regulations on the Quality Management of Construction Projects', and are usually determined based on project characteristics, material performance, and industry practices.
It should be noted that the starting point of the warranty period is generally the date of house delivery and use, and normal use conditions must be met. Damage caused by unauthorized structural modifications, improper use, or force majeure by the user may not be covered by the warranty. It is recommended that homebuyers clarify the warranty terms for each part when signing the contract and retain relevant documents for rights protection.
