Renovation is a complex process, and there are three renovation methods: full contracting, half contracting, and clear contracting. Among them, clear contracting renovation requires special attention, as it is also prone to traps. If you accidentally fall into the traps set by the decoration company, not only will the renovation not be done well, but you will also be "squeezed for profit". So today, I will summarize the common decoration traps in clear contracting for everyone.
Clear contracting, also known as labor-only contracting, refers to a project contracting method where the owner purchases all materials by themselves and hires a decoration company or decoration team to carry out the construction. Due to the wide variety of materials and the large difference in prices, some people worry that others purchasing materials on their behalf may profit from it, so some decoration households adopt the decoration form of buying materials by themselves and only contracting for clear labor.
1. Pay more attention to concealed projects There are traps in hydropower transformation
Hydropower transformation is an important project in the home and is also a relatively concealed project. If these projects have problems in the future, they will be difficult to repair, so the hydropower transformation project must be done well during the decoration process. During clear-contracting decoration, you must supervise the craftsmanship of the hydropower construction personnel and strictly check and accept the project.
1. Downstream pipelines
When the construction team is carrying out decoration, they may pour construction waste such as cement, sand, and concrete blocks into the sewer for convenience. This will cause the sewer to be blocked, and problems such as poor drainage and overflow of sewer water will occur in future use.
2. Wire joints
In addition to the down pipeline, when electricians install sockets, switches and lamps, if they do not wire according to the construction requirements, it will not only lead to high power consumption, but also may cause short circuit when using high-power appliances such as water heaters, air conditioners, and refrigerators, and even burn the switches and sockets, which has a certain impact on home electricity safety.
3. Wire threading
At present, the wire installation in most homes requires threading, and almost all wire threading now uses PVC pipes, which are buried hidden in the wall. Owners cannot see the threading effect of the construction workers. If the workers deliberately cut corners, use wires with joints in the pipe or thread several wires into the same pipeline, it will affect the future electricity safety.
2. Safety and firmness are important There are many traps in wall decoration
In clear-contracting decoration, wall construction also needs more attention. The base treatment of the wall, grooving, painting, tile installation, etc., the time and effort spent on it should not be underestimated.
1. Wall grooving
If pipelines need to be buried hidden in the wall, grooving must be done on the wall. Some unqualified construction teams conduct grooving construction brutally, which destroys the load-bearing structure of the wall and may also damage other pipelines. Before construction, it is necessary to confirm the pipeline direction with the construction captain, and have different grooving schemes for different walls. Load-bearing walls are not allowed to be grooved, and the floor slab cannot be damaged, etc.
2. Base treatment
The base layer must be treated well before the surface decoration of the wall. Some construction teams will cut corners here to "squeeze profit". Problems such as uneven base layer and uneven primer application will, in serious cases, lead to discoloration of latex paint and falling off of tiles in the later stage.
3. Wall painting
Latex paint is currently a commonly used wall decoration material. There are brushing, roller coating, spraying and other methods in the construction process. If the workers are perfunctory during the construction, color difference will often occur, especially for dark latex paint.
3. Clear-contracting decoration requires caution Pay attention to floor decoration traps
During the clear-contracting decoration process, the construction project that needs attention also includes floor decoration, floor leveling, floor paving... The handling of these small details is an important factor affecting future use.
1. Floor leveling
The floor of some houses is not flat enough, especially when renovating a second-hand house, after removing the original decoration, the floor becomes uneven. Leveling is required during the construction process. If the workers are not careful, it is easy to cause the situation of "the more leveling, the more uneven". The continuous increase of cement mortar on the ground will also cause excessive load on the floor slab.
2. Tile paving
Tile paving is a highly technical process. If workers cut corners on the cement mortar, it is easy to cause hollowing and uneven joint alignment, which will easily lead to tile falling off in later use.
3. Floor paving
There are also many traps in the floor paving process. The common one is that the floor paving is uneven, with uneven heights or uneven joints, etc. Most of these are caused by the carelessness and sloppiness of the construction personnel.
4. Do not ignore detail decoration Construction traps are everywhere
In addition to the relatively large decoration links, there are also certain traps in some detail decorations. If you want to get rid of these decoration regrets, you need to be especially careful when handling construction details.
1. Joint treatment
The joint between doors, windows and the wall must be filled, or where two different colors of paint meet, transitional treatment is also required. Some careless masters lack patience when dealing with filling and joint positions, which will lead to paint mixing at the joints and incomplete filling of door and window gaps.
2. Small surface treatment
"Small surfaces" refer to some small places that consumers usually cannot see with their eyes, such as the upper edge of door frames and the bottom of window sills. Cut corners can be done in these places, so when the owner accepts the house, he must check all surfaces of each building material.
3. Hardware installation
In the later stage of decoration, owners may buy a lot of hardware, such as towel racks, storage racks, etc. Often these installations require drilling holes on the wall. It is better to drill according to the hydropower drawings, and at the same time, be careful to avoid breaking the wall base such as tiles when drilling.
5. Advantages and disadvantages of clear-contracting decoration
Advantages: Among the above two types of decoration, clear-contracting decoration is the most cost-saving decoration method. It is very suitable for owners who have good material purchasing ability. First of all, the degree of self-control is high, you choose materials by yourself, which fully reflects your own wishes; secondly, the cost is relatively saved; thirdly, you have an intuitive understanding of the type, price and performance of the materials. In an ideal state, this is the most cost-saving approach, but the owner will naturally spend a lot of time.
Disadvantages: However, in clear-contracting decoration, customers may not be able to buy cheap goods, and unfamiliarity with the quality of goods often makes them suffer "in silence". The main materials have high transparency, but the water of auxiliary materials is too deep for first-time decorators, and it is difficult to figure it out in a short time. In addition, purchasing materials by yourself will also cause disputes with the construction party. The reason is that once there is a shortage of materials during the decoration process, the owner has to replenish the materials immediately. If the materials cannot be delivered on time according to the construction progress, it will delay the construction period.
