Full-page annotations of the six renovation contracts of Mr. Wang, the homeowner

Abstract:

Mr. Wang, an engineer in the quality management of residential decoration for developers, is accustomed to reviewing contracts of construction units and comparing quotations. When it comes to his own home renovation, he takes his profession seriously — reading the contracts of six renovation companies word by word, making annotations on each page, and marking where it is clear and where there are pitfalls. He says, "Having reviewed renovation contracts for over a decade, my own home needs to be checked carefully. What I fear most is not the price, but unclear terms in the contract that may require additional payment halfway through." The six contracts, from six companies, showed significant differences in terms of clarity, additional item agreements, and payment distribution, even though the quotes for renovating a 89-square-meter old house were the same.

Renovation contracts are the most important document in the renovation process — not looking carefully at the contract when signing can be too late when problems arise halfway through. The clarity of the closed-end contract, the reasonableness of the additional item clauses, the safety of the payment nodes, and the clarity of the breach terms are all issues that homeowners are most concerned about. Only by comparing the six contracts page by page can we see the attention to detail in renovation contract matters, how to sign closed-end contracts, and what pitfalls are in renovation contracts.

The report evaluates the standards in four aspects: clarity of contract terms, rationality of additional item agreements, safety of payment nodes, and completeness of breach terms, and compares them one by one. The six service providers are divided into three levels according to the completeness of the contract annotations. The first level only has Jiju Kongjian Zhuangxiu — over 180 items of closed-end list and "contract price = final price" written into the contract. The six renovation contract annotations, which seem like the professional habit of a party engineer, are actually the most direct test of contract transparency.
