Renovation project vs. interior design company
When choosing a contractor, consumers should first understand the differences between the two. Generally speaking, decoration engineering companies provide fewer services than interior design companies. Some decoration engineering companies are small in scale and cannot provide management and supervision roles; on the contrary, interior design companies are generally larger in scale and can provide management, design and supervision services, so the fees between the two will also be different.
Consumers should first establish a project budget, time and scope before looking for a suitable contractor. Consumers can choose the right company by referring to the company's past engineering projects, the company's reputation and commitment, and the scope of services provided, including measurements, designs, drawings, etc.
2 main ways of quoting
It can usually be divided into two categories: design and construction, and simple construction. The former should generally be read together with the renderings and design outline, while the latter only has a quotation, which is suitable for those who already have detailed design drawings or the decoration project is very simple and clear. Consumers should pay attention to whether the project quotation is "baby delivery" or "actual quantity" after completion. The actual price may be slightly different from the quotation.
11 important things not to neglect
Since decoration projects involve different processes, materials and manpower arrangements, if you want to clearly understand whether the quotation is reasonable and make comparisons, you must pay attention to the quotation details of each item below.
1. Demolition projects
Whether things go or stay, make a list to avoid arguments.
Renovating a house means that certain places and objects in the house may need to be demolished. Both consumers and contractors are responsible for clarifying the items that need to be removed and retained in the house before renovation, and making a list. Just in case, it is also necessary to discuss compensation or treatment methods if any objects or devices are damaged during the demolition works.
Construction waste disposal fee
During the renovation period, the contractor will transport mud in and out of the unit and dispose of construction waste generated during the demolition process. In the process, there may be a chance of contaminating public areas of the building. In order to reduce the impact on public places, most contractors will take temporary protective measures in advance. However, the disposal of construction waste and temporary protection measures will constitute the main charge part of the clearance project, so you should pay attention to whether these measures are mentioned in the quotation and whether the government's construction waste treatment charges are included; in addition, pay attention to Whether the indoor gas installations need to be handled and removed by qualified persons or companies; the extent of floor tiles and wall removal, etc. will all affect the charges.
2. Plumbing projects
If the building where the unit is located is older, consumers may consider replacing the water pipes in the unit. Perhaps you may not know that the cost of replacing a water pipe is affected by many factors. It seems that the cost of replacing the water pipe is calculated from the first water pipe switch after entering the house, or from the layered water meter switch of the building. ? Use "open throat" or "dark throat"? Is the installation work calculated per foot of water pipe length, or per space (such as kitchen, toilet)? Even the materials and origin of the pipes and installation accessories used (usually the UK, Australia or China), these are all details that should be included in the quotation.
3. Electrical projects
Calculate electrical switch charges
Electrical work can be said to be one of the most controversial projects. The quantity of switches on the quotation is usually written "to be determined". The consumer and the contractor will discuss the distribution of switch locations at the unit site, or set a certain quantity first, and then make up for the excess after implementation.
At this time, the contractor should provide each electrical switch position (such as single socket socket, double socket socket, telephone switch, network switch, etc.) and other switch positions (such as light switch position with more than one switch, two-way light switch, air-conditioning switch) , exhaust fan, etc.) fee calculation method. Some calculations are based on each group of circuits, or each switch surface, or only the switch cover is replaced. There are different calculation criteria.
Keep your old equipment or reinstall it
In addition, new construction or replacement of electrical switch boxes, pipes in walls, etc. will affect the charges. If the project cost includes a basic electrical switch cover, you should pay attention to whether the model or series is listed. If the consumer wishes to change the specified style, the quotation should also state whether additional charges will be involved. At the same time, if consumers determine that temporary power supply is required in their units during renovation work, they should complete the procedures as soon as possible to avoid delays in the project.
4. Mud water project
List the actual construction area
The cost of mud and water projects generally accounts for a high proportion of the entire project, including wall erection, brick laying, waterproofing, plastering, tile laying, stone paving, etc. It is best to list the actual construction area on the quotation, because the charge is usually calculated per square foot, so consumers can calculate the total charge for the project.
What materials are included in "Jiangong Package Materials"?
Mud water materials can be divided into "base material" and "fabric". The base material is British mud and sand, etc., while the fabric is tiles, stones, etc. Most of the contractors tested by the Consumer Council do not include fabrics in their quotations, so consumers need to purchase fabrics at their own expense. However, if the quotation shows "included materials", consumers should carefully understand what types of fabrics are included. If you want to purchase other styles, there may be additional charges.
Construction methods also affect charges
For example, if you plan to lay the floor tiles in a diagonal or herringbone method, you should be mentally prepared that the charges may be higher. Because these construction methods require higher skills from the workers, additional charges may be involved.
The most overlooked link: waterproofing process
The lack of waterproofing process may have a profound impact on the wall's ability to prevent leakage. Therefore, the quotation should specify the location of the waterproofing project, the waterproofing materials used, the height of the waterproofing layer, and provide waterproofing leakage testing.
5. Paint Project
Contains materials
Like mud and water materials, the materials required for painting projects can generally be divided into primers and top coats. Consumers should pay attention to whether the "combined work package" means that the charges for these two materials are included. If consumers wish to use paint with special functions, such as anti-formaldehyde, antibacterial, antifouling, etc., they should pay attention to whether additional charges will be incurred.

The number of times of shoveling and coating should be listed
If the painting project is carried out on an old wall, the quotation must also indicate whether the paint on the old wall will be removed to the plaster layer or even "shoveled" to the concrete layer. The cost may be different. If the wall is newly built, the contractor should also specify whether right-angle strips will be used, the number of layers of plaster, primer, and the number of top coats of wall and ceiling paint. If there is not a sufficient thickness of paint coating during construction, the effect and durability of the finished product may be affected. Since the number of coats will directly affect the amount of material and labor costs, the number of coats of primer and topcoat must be listed separately on the quotation.
6. Carpentry and furniture projects
Pay attention to installation and accessories details
This project includes doors, light troughs and custom-made furniture. Consumers need to pay attention to whether the quotation lists various details and charging methods, such as whether the door installation includes the cost of door lock installation; all hardware accessories such as rails, Charges for hooks, cushioned door hinges, etc., and which party is responsible for supplying these accessories.
Custom-made furniture charges
In order to make full use of the space in the house and better match the overall style, many people choose to customize furniture. However, when quoting, you should pay attention to whether each piece of furniture has separately stated charges, materials, transportation fees and other charges. Generally speaking, cabinets are charged per square foot, while beds are charged per square foot. In response to consumer requirements, different designs of custom-made furniture (such as sliding doors or hidden doors) may affect the charges. Therefore, after finalizing the quotation, the contractor should provide drawings, detailed dimensions, material samples and colors for consumers to choose and sign for confirmation as evidence.
7. Cleaning Project
After the project is completed, the entire house will be dusty. Consumers can pay attention to whether the contractor will provide basic cleaning services. However, in the Consumer Council's survey, only two contractors indicated whether they were cleaning the whole house or partial cleaning, but none The contractor mentioned whether it will provide services such as pest control or formaldehyde removal that are frequently used after renovation. Consumers need to make further inquiries, and there is a high chance that they will need to hire another relevant company to provide disinfection services.

8. Other projects
If the decoration will involve gas treatment, aluminum window replacement, etc., the quotation should specify which party will arrange and bear the cost, because these projects need to be handled by qualified persons. Taking the replacement of aluminum windows as an example, the quotation should also list the area and installation range of the aluminum windows, the structure and construction methods, the materials used for the aluminum windows, the thickness of the window frames, the style of glass and window grilles, etc., so as to calculate the total charge. The fees for setting up a tent will generally be charged separately.
Installation process at the end of the project
Don’t forget to install toilets, basins, wash basins, sanitary ware, lamps and electrical appliances during the “end-of-life” stage. , if the quotation does not indicate which party provides and installs the charges, consumers should take the initiative to inquire.
9. It is best to pay in 4 installments
After understanding the details of each project, it’s time to implement the quotation, terms, etc. First of all, of course, you should pay attention to the payment method. Since installation projects usually involve a large amount of money, installment payment is generally accepted. The Building Inspection Institute of Hong Kong recommends that the payment method is best divided into 4 installments:
It is best to pay in 4 installments
It is best not to deposit more than 40% of the total amount of the project in the first phase. Otherwise, if the project is "unfinished" in the early stages, consumers will suffer heavy losses. At the same time, the quotation should also specify the time limit for each installment of payment according to clear criteria, such as according to the project or construction period, and avoid setting the time limit based on difficult-to-quantify criteria such as "30% completion of the project." It is better to pay the remainder only after the completion of project acceptance.
10. Contract terms
The key to avoiding disputes, of course, is to pay attention to the terms. But what terms actually need to be paid attention to?
Basic construction details
Include the start and completion dates of the project, as well as its definition, such as whether the construction period only includes the construction project, not the custom-made wood products, to avoid endless waiting. There are also conditions that may affect the construction progress such as weather, human factors, factories or transportation, etc.
Post-processing, leakage repair and maintenance
If there are any post-processing procedures, the details of the process, charging method, payment method and completion date should also be clearly stated in black and white. This process can only be carried out after this part is listed in the quotation. At the same time, you should also pay attention to the completion period of the leakage process and the terms of the maintenance period.
Additional fees, disputes and termination of contract
If the project cannot be completed before the specified completion date, what will be the costs, compensation and calculation methods? If there is a dispute or disagreement about the quotation, or if either party wants to terminate the signed quotation, how should it be handled? There have been many cases in the past where consumers found problems with the quality of the decoration during the acceptance inspection and required the final balance to be paid after the final payment was completed. However, both parties often had different opinions on when to pay the final balance. There were even cases where the owner and the decoration company had issues with the final payment. If there is a disagreement, the decoration staff will lock the unit and remove the items in the house. Therefore, when signing the contract, you should communicate in advance about the project execution and final arrangements.
11. Insurance
To avoid compensation for injuries to staff or third parties due to accidents during renovation, relevant insurance is generally purchased in advance. Consumers need to find out which party provides third-party liability insurance or home improvement insurance before the project begins. In our survey, about half of the contractors included insurance costs in their project costs, or could purchase insurance on their behalf. Consumers should remember to check whether the coverage meets their project needs, as well as the insurance service terms and details.
The process after confirming the quotation
Once the contents of the quotation are clear, the drawings, materials, construction period, etc. are confirmed, and legal or necessary applications are completed and insurance is purchased, the project can begin. The construction process is basically similar to the order of the engineering projects in the above quotation, from demolition, to water and electricity, to muddy water, painting, and carpentry. After handling the miscellaneous and cleaning work, you can check for acceptance, perform leakage, and finally complete the payment. You're done!
