As an important part of the building, doors and windows are related to the safety of the home. As people\’s living standards improve, many consumers are becoming more and more particular about their living experience, and undoubtedly have higher and higher requirements for the quality and performance of doors and windows. Generally speaking, when we buy a house, the entrance door is installed by the developer. But many people will struggle with this question, that is:Does the door installed by the developer need to be replaced?

The reason for such confusion is that most people say it is because they heard some owners say that the security doors provided by developers are of poor quality and have very thin door panels. Engineering doors are easy to be stolen. Another worry is the fear of encountering construction workers with bad intentions who may secretly assign keys.

In fact, to put it bluntly, the quality of the anti-theft doors provided by developers is not bad, otherwise the developer\’s building quality inspection will not pass. And now security doors are equipped with two sets of keys, one is the decoration key (A key) and the other is the master key (B key). The decoration key A is reserved for the construction workers. After the decoration is completed and the owner opens the door with the B key, the A key in the hands of the construction workers cannot be used.

Whether the anti-theft door installed by the developer needs to be replaced or not, the most important thing is to look at these two points:

1. Understand the security level of the door

The anti-theft levels of anti-theft doors are divided into four levels: A, B, C, and D. Among them, level A is the highest. I want to know what the developer installs. What level of security door is it? We can look at the side of the security door. If there is a steel seal mark, it is a security door. Otherwise, it is recommended to replace it. If the security level is A or B, it is recommended that there is no need to replace it.

2. Understand. Door lock cylinder

In addition to the safety of the anti-theft door itself, the most important thing is the lock cylinder. The door lock cylinders currently on the market are also graded. , Class B, Class C. Among them, Class C has the highest anti-theft properties. Due to cost considerations, the initial locks installed by some developers are onlyClass A locks, so it is recommended to replace them with lock cylinders that are at least Class B or above. Class C is the best, so you can live more securely.

At the end:

In fact, regarding whether to replace the door pre-installed by the developer, I personally suggest that unless the security level of the anti-theft door is very low, simply change the lock. Nowadays, smart door locks are also more popular. We can also replace them with smart door locks, which makes it easier to go out and no longer needs to carry the key. If you are not satisfied with the color of the door installed by the developer, it is not recommended to spend a lot of money to replace it. Just ask a painter to paint the color of the inner surface of the door, which can achieve the effect and save money. Finally, if you really decide to replace the door, the best time to replace it should be after the masonry comes in or before the completion. If you wait until the decoration is completed, you will be in a lot more trouble.
