At the end of the year and the beginning of the year, especially from the end of December to March of the following year, with the delivery of batches of new houses, a renovation boom also follows.

Faced with new homes, many owners will face a common question: Do the doors and windows pre-installed by the developer need to be replaced?

After all, it is expensive to replace the windows of the whole house, especially the broken bridge aluminum or system windows with profiles above 108 , easily tens of thousands, which is undoubtedly a considerable expense for ordinary families.

Hand Notes happened to have gone through the renovation process of half-replacement and half-retention of doors and windows, and has lived in this house for 6 years. Based on this, I will talk about my experience in this issue. My true feelings, I hope it can provide some reference for you who are struggling with this matter.

1. Entry door: balance of safety and convenience

In terms of the choice of entrance door, I finally decided to keep the one pre-installed by the developer. There are many considerations behind this decision.

First of all, from the perspective of security, the entrance door is arranged from high to low., divided into four levels: A, B, C and D, and my home is equipped with the highest level of Class A security doors.

This can be easily verified through the steel seal on the side of the door. If the word \”A\” is written on it, it is a Class A security door, and the same applies to other grades.

Although I did not replace the entry door, I did upgrade the lock cylinder. This is because I personally don’t like to go out with my keys, and the emergence of smart locks just solves this problem for me.

In addition, during the renovation period, since I am often not present, the smart lock can also set a temporary password and provide it to the courier guys, allowing them to deliver the goods directly to the doorstep, which greatly improves the convenience of life.

Moreover, smart locks have a more advanced appearance and richer and more practical functions. For example, my smart lock is equipped with cat eyes and With the video intercom function, visitors can be clearly seen and monitored in real time even if they are not at home.

Of course, I am not saying that everyone must replace the lock cylinder. If your entrance door is also a Class A anti-theft door and the lock cylinder is the highest Class C, and you are not interested in these functions of the smart lock, or the decoration budget is limited, then you can keep the original lock cylinder.

Among them, the super-B grade is the C-grade lock cylinder

However, even if the safety performance meets the standards, some owners are still dissatisfied with the style and color of the entrance door. At this time, you can consider changing the color and style of the door by painting or applying felt.

The home security doors provided by developers usually look old-fashioned

Both methods are relatively economical, but they are difficult to operate. It may require some hands-on ability. If you are interested, you can find relevant tutorials and cases online (if you have poor hands-on skills, it is recommended to pay some money to let the decoration master help)

Of course, if you are interested in the door style and If the color has higher requirements, directly replacing a door is also a feasible option.

To sum up, if your home’s entrance door is a well-known brand of Class A anti-theft door + Class C lock cylinder, you can keep it. If you are just not satisfied with the style and color of the door. , then you can consider personalizing it by changing the color or applying felt. On the other hand, if you have higher requirements for the overall performance and appearance of the door, then replacing a door is also worth considering.

As far as my personal experience is concerned, the entry door that only replaced the lock cylinder still performed well after two years of moving in. . Except for the occasional slight squeaking sound at the door hinge, there are no other problems. Moreover, the use of smart locks also makes me feel unprecedented convenience and peace of mind.

2. Windows: quality and priceTrade-offs

In terms of window selection, all the windows pre-installed by the developer were retained, such as the dining room and most bedrooms, etc., and only the windows that were not installed, such as the living room balcony , the complimentary study room and the expanded second bedroom, etc., I installed the 115 profile series broken bridge aluminum doors and windows.

The main reason why I do this is because the price of broken bridge aluminum doors and windows is really expensive. After consulting with many merchants, I found that the price of 108 profile broken bridge aluminum doors and windows ranges from 600 yuan to 800 to 900 yuan per square meter, while the brand\’s system doors and windows are even more expensive, more than 1,000 yuan per square meter. If you install a floor-to-ceiling window with a panoramic view on a large balcony, the cost may be tens of thousands.

In fact, my family spent nearly 20,000 yuan on installing windows, which only sealed about 20 square meters of windows. . If the whole house is replaced with broken aluminum doors and windows, the cost may be as high as tens of thousands of dollars. For example, neighbors in a community with the same apartment type spent about 40,000 yuan to replace their windows. In the bungalow area, due to the higher floors and large windows, some neighbors even spent about 100,000 yuan to replace the windows.

The balcony is too big to seal the windows

However, from the experience point of view, the broken bridge aluminum doors and windows are indeed worth the price. After closing the window, the sound of the traffic downstairs almost completely disappears. This is because the broken bridge aluminum doors and windows are made of 5+25A. +5 double steel The white glass design has excellent sound insulation and sealing properties. Even in the winter when the north wind blows, you can hardly feel the cold wind when you reach out to the window. In contrast, the windows pre-installed by the developer are excellent in sound insulation and sealing. Seems a little inferior.

On the side of the road, the sound insulation performance of windows must be good

However, this does not mean that I encourage everyone to replace their windows. The specific situation requires detailed analysis. If your home uses plastic steel windows that were popular in the 1990s, it is indeed necessary to replace them because plastic steel windows are outdated and outdated. They are not only low-cost, not strong enough, but also prone to aging and deformation.

Now most developers will pre-install aluminum alloy windows, and even in some high-end residential areas and residential areas with fine decoration, they will also pre-install broken bridge aluminum windows. For these pre-installed windows, if they are accepted. If it is qualified and there are no quality problems, there is generally no need to replace it because the national quality acceptance standards for windows have become more stringent than before.

Aluminum alloy doors and windows brought by the developer

It is also worth mentioning that developers usually install windows first and then build exterior walls Insulation. Therefore, the sealing of pre-installed windows is usually stronger than that of post-installed windows. This is one of the reasons why some owners will find that the sealing of new windows is not as good as that of old windows.

So under what circumstances is it recommended to replace windows? I think there are two main situations: one is close to the main road? , airports, or shopping malls and other noisy places; the second is when you are not short of money and want to improve the quality of life.

Of course, ifIf you decide to replace your windows, be sure to do market research and budget planning in advance. Because the price system of broken bridge aluminum doors and windows is very complicated and confusing, it is difficult for even designers to easily distinguish their advantages and disadvantages and prices.

In general, after 6 years of moving into my home, whether it is the aluminum alloy doors and windows pre-installed by the developer, or my own The doors and windows that were replaced have performed quite well. As for how to choose, I think the key is to weigh and make decisions based on your actual situation and needs. I hope my sharing can inspire and help you.
