Does the property cause fire paralysis?

Send a formal "work contact letter" to the owner, explain the current situation, and demand that the warranty be rectified according to the specifications, otherwise it will be responsible. . . Wait a minute. Ask the other party to sign the copy of the contact letter.

According to the law, you shouldn't accept it if he doesn't do it well. Now that you have checked in, it means you agree to accept it. In case of an accident, your property management is of course responsible. The letter above is good evidence.

It is best to send it once every two months, or you can complain to the Construction Committee and the quality inspection department. The fire department doesn't need to do this. They will seal the door.
