Details of the home improvement contract to pay attention to

2. Warranty Terms: Since most decoration work involves on-site labor rather than factory-made components, some minor quality issues are unavoidable. To protect yourself, always keep a copy of the original quotation provided by the company. This helps prevent unexpected price changes during or after the contract is signed. Make sure the warranty terms are clearly outlined in the agreement—whether it covers only the workmanship or also the materials, and whether there are any limitations or conditions.

3. Construction Based on Drawings: Always follow the design drawings that have been officially approved by you. If any part of the work doesn’t match the plans, you have the right to request corrections. At the end of the project, water and electricity costs can add up significantly. Be sure to specify who will cover these expenses in the contract. Also, clarify the unit prices for each task. Some details might be decided after the project starts, which could affect the overall cost and schedule.

4. Water and Electricity Usage: During the renovation process, water, electricity, and gas are commonly used on-site. These utilities may increase the final bill, so it’s important to agree on how these costs will be handled in advance.

5. Mid-Term Payment: Most contracts mention the mid-term payment as “when the project is half done,” usually referring to the completion of woodwork. However, it’s better to define more specific milestones to avoid confusion later on.

6. Additional or Reduced Work: It's common for projects to change during the process—like adding more cabinets or modifying the plumbing. Make sure any changes are documented and agreed upon in writing to avoid disputes.

7. Payment Method: A typical payment plan includes a 60% deposit upfront, 35% after the woodwork is completed, and 5% upon final acceptance. Ensure the payment schedule is clear and aligns with the project milestones.

8. Specific Requirements and Deadline: Clearly state the exact requirements and the expected completion date in the contract. Many homeowners overlook these details, which can give unscrupulous companies an opportunity to delay the project or cut corners.

9. Material Specifications: The contract should include the exact brand and model of all materials to prevent the company from using substandard products. This ensures transparency and accountability throughout the process.

10. Warranty Responsibility: The warranty clause must be detailed and legally binding. If the issue is due to poor workmanship or materials, the company should take full responsibility. However, if the problem results from improper use by the homeowner, both parties should negotiate a solution.
