Renovation of old house Wooden Doors: Replacement and size matching tips

In the renovation project of old houses, the replacement of wooden doors is a key step to enhance the texture and practicality of the space. However, problems such as aging walls and irregular door opening sizes in old houses often cause many teams to encounter adaptation difficulties when making replacements. Mastering the scientific replacement process and precise size matching skills can not only avoid rework and waste, but also ensure the stability and aesthetic appearance of the wooden door after installation. Now, based on years of practical experience in the industry, I will share the core points for replacing wooden doors in old house renovations.

I. Preparatory Work: Conducting a thorough basic survey is the key

Before replacing the wooden doors in an old house renovation, do not blindly purchase products. The preliminary survey work directly determines the smoothness of the subsequent process. First of all, it is necessary to focus on checking the condition of the door opening. Common problems in old houses such as wall settlement and plaster layer peeling may cause the door opening to deform and have dimensional deviations. It is recommended to first remove the loose wall materials around the door opening to expose the original wall structure, and then measure the dimensions.

It should be emphasized here that precise measurement is the core prerequisite for size matching. When measuring, three key dimensions should be taken into account: the height, width and thickness of the door opening. It is recommended to measure three different points for each dimension, and take the smallest value as the reference dimension. For instance, the height can be measured at three points on the left, middle and right sides of the door opening, and the width can be measured at three points at the top, middle and bottom to avoid misjudgment of the size due to local protrusions or depressions. At the same time, pay attention to the type of wall of the door opening. Different walls such as brick-concrete and light steel keel also have an impact on the fixation method of the subsequent wooden door installation.

Ii. Size Matching: Avoid these common misunderstandings

When many people replace the wooden doors of their old houses, they tend to fall into the misunderstanding of "directly customizing according to the current door opening size", but they ignore the particularity of the door openings of old houses. Due to their long service life, some door openings may have slight tilting or irregular deformation. If they are custom-made exactly according to the current dimensions, problems such as uneven door gaps and poor opening and closing may occur after installation.

The correct dimension matching technique is: on the basis of measuring the reference dimension, reserve a reasonable adjustment space. Under normal circumstances, a gap of 5 to 10mm should be reserved for both the height and width of the door opening for leveling and adjustment during subsequent installation. Reserve 2-3mm in the thickness direction to facilitate the filling of sealing materials. For door openings with severe deformation, correction treatment should be carried out first, such as filling the depressions with cement mortar and removing the protruding parts. After the door openings are regulars, the dimensions should be confirmed.

In addition, attention should be paid to the compatibility between the opening method of the wooden door and the size of the door opening. For instance, for inward-opening doors, space should be reserved for the door frame to fit the wall, while for outward-opening doors, the passage area outside the door should be taken into account to avoid affecting the user experience due to insufficient size reservation. Meanwhile, the thickness of the door frame should match that of the wall. If the wall is too thick or too thin, corresponding connecting parts or filling materials should be prepared in advance.

Iii. Replacement Practice: Details determine installation quality

After the dimensions are confirmed to be correct, the practical operation of replacing the wooden door begins. First, the old wooden door needs to be removed. During the removal process, it is necessary to pay attention to protecting the wall structure around the door opening to avoid wall damage caused by violent removal. After the demolition is completed, clear the debris and dust inside the door opening, and check the flatness and verticality of the door opening. If there is any deviation, it needs to be corrected with a leveling layer.

When installing a new wooden door, first fix the door frame. The fixing points of the door frame should be evenly distributed, and the spacing should not exceed 600mm to ensure that the door frame is installed firmly. After the fixation is completed, adjust the verticality and levelness of the door frame, with the deviation controlled within 2mm. Then install the door leaf and adjust the gap between the door leaf and the door frame to ensure smooth opening and closing of the door leaf and uniform and consistent door gaps. Finally, fill the gap between the door frame and the wall. You can use foam sealant for filling. After filling, wait for the foam sealant to fully cure before carrying out surface decoration.

It should be noted that during the renovation of old houses, the replacement of wooden doors needs to be coordinated with the overall decoration process. For instance, the installation of wooden doors should be carried out after the wall plastering and floor paving are completed to prevent damage to the wooden doors caused by subsequent construction. At the same time, after installation is completed, proper protection of the finished product should be carried out to avoid collision or scratches.

Iv. Post-maintenance: Extend the service life of wooden doors

After the wooden door is replaced, reasonable later maintenance can effectively extend its service life. Within one week after installation, avoid opening and closing the door leaf forcefully and do not place heavy objects on it. In daily use, keep the room well-ventilated and dry to prevent problems such as deformation and cracking of wooden doors due to moisture. Regularly inspect the fixed parts of the door frame. If any looseness is found, reinforce them promptly. For stains on the surface of wooden doors, you can wipe them with a soft damp cloth. Avoid using strongly corrosive cleaning agents.

In conclusion, the key to replacing wooden doors in old house renovations lies in precise size matching and standardized practical operation procedures. Mastering the above skills can effectively solve the common problems in the replacement of wooden doors in old houses and improve the quality of decoration. Whether it is a decoration team or a real estate renovation enterprise, when carrying out related projects, they should pay attention to these key details to ensure that the replacement of wooden doors not only meets practical needs but also conforms to the aesthetic requirements of the space.
