Does the owner have the obligation to suppress floor heating before renovation?

First of all, no one wants to encounter this kind of thing, and can only express sympathy for you. Then tell you that this is a wrangling relationship, and the final responsibility may be on you.

In principle, the company of floor heating construction has no obligation to carry out suppression experiments for users. According to the floor heating construction contract, the floor heating company will suppress the floor heating after the construction is completed and then deliver it to the real estate developer. As long as the floor heating company can provide handover procedures and acceptance procedures at that time, it has nothing to do with others. At this time, the floor heating construction company only has a warranty period. According to you, the house has been built for two years, and the warranty period of floor heating is generally one year. So the floor heating company can only assist you in maintenance at this time, but all the maintenance costs are borne by you.

Before the property is renovated, the user must have a renovation permit, which will explain some situations. If the user is informed in writing to suppress the floor heating before the renovation, and you fail to do so, it is your responsibility, and the property has already played the obligation to inform.

The floor heating was detected, how to prove that the floor heating was not damaged during the decoration? This is an unclear question. If I were a property, I would take the repressive handover procedures given to me by the construction party as evidence. What evidence can you have to prove that you didn't damage the floor heating?

From the downstairs of your house, it is your floor heating that leaks. If it causes losses to his house, you should bear the responsibility.

Judging from the industry I am engaged in and the similar situation I know, you will always be the victim in this incident. If you resort to legal solution, I am not very clear about the relevant legal provisions and can't talk nonsense with you. Let's try to compensate as much as possible through negotiation. It is difficult to protect the rights of small property houses.
