First, time preparation:
Generally, it is necessary to start preparing for the renovation about 2 months before the renovation. The initial preparation basically includes the following aspects:
1 Check home improvement pictures online and master the decoration style you want? Click to enter the home improvement photo gallery.
Find a suitable decoration company, discuss the decoration scheme with the designer, determine your own decoration budget and sign the decoration construction contract.
Visit the building materials market: mainly select some building materials that need to be booked in advance, such as floor tiles, which often require consumers to pay a certain deposit to the merchants. The tile category is around 100-200. You can try to lower the price with the merchant, or negotiate a refundable deposit, which can avoid many unnecessary losses.
Second, the material preparation:
1, Ben and pen
It is particularly important to visit the building materials market, whether it is to record the decoration knowledge, the price of the product or the contact information of the manufacturer, the design of the home, the cost during the decoration and so on. , can be carefully recorded for reference. Of course, the best thing is to record your daily renovation progress and expenses, so that you can control the budget.
2. Calculator
With a calculator in his hand, he is not afraid of profiteers setting traps on the total price. Remind everyone that after negotiating the price with the merchant, you must use your calculator to check all the total prices again. If the total price is wrong, the unit price we have worked so hard to cut will be meaningless.
3. Tape measure
Measure the house, furniture, cupboard and floor. In short, in the process of decoration, we can't lack him at any time.
Third, the capital preparation:
If your renovation budget is 50,000 yuan, you will often find that your actual expenditure will rise to 60,000-70,000 yuan after renovation, so I suggest that you prepare a little more than the actual budget at the beginning. At the same time, the transportation, telephone and catering expenses will rise a lot during the renovation, so be prepared.
sign a contract
When signing a contract, we must stick to the principle.
Pay attention to the following aspects when signing a contract:
1 time limit agreement? 2 Payment Method 3 Payment Time of Interim Payment 4 Increase or decrease Item 5 Warranty Terms
5 water and electricity costs? 7 Construction according to the drawings 8 Time and frequency of quality inspection.
expand on
When signing renovation contract, we should pay attention to the following aspects:
1 Term Agreement: A 2-bedroom apartment with a general area of 100 square meter. If it is simply decorated, the term is about 35 days. For insurance, the decoration company will generally stipulate the term as 45-50 days. If you are in a hurry to move in, you can discuss this clause with the designer when signing the contract.
2 Payment method: Generally, in renovation contract, 60% of the down payment is agreed, 35% is paid after the carpentry is qualified, and 5% is paid after the completion. If you follow this form of payment, you have paid about 95% of the expenses to the decoration company after half of the construction period. If something goes wrong in the later period of decoration, it will be difficult to restrict the decoration company financially. Therefore, it is suggested that when signing the contract, the down payment can be reduced to 30% and the interim payment can be 30%.
Interim payment: the interim payment time agreed in the general contract is simply marked as "halfway through the project, carpentry is finished". However, a construction site is often a multi-project crossover operation, and more than half of the regular construction period should be: the end of wood production; Kitchen and bathroom walls, floor tiles and ceiling bottoms; End of wall leveling; The electricity reform is over.
3. Add or remove items: When decorating, it is easy to add or remove items, such as making more cabinets and changing several meters of waterways. These are all due when you finish. So what should the unit price of these items be? If the construction has already started, then the design may have the final say. Therefore, if possible, it is best to make a copy of the original complete quotation of the decoration company, so as to avoid the decoration company from changing the price when signing the contract or adding or subtracting projects.
Also note that at the time of final settlement, the increase or decrease fees you should pay should be signed by you before the project starts. If you don't sign for it, you don't have to pay the corresponding fee.
Warranty clause: The whole process of decoration is still mainly hand-made on site, and it has not been fully industrialized, so it is inevitable that various fine quality problems will occur. During the warranty period, the responsibility that the decoration company should implement is particularly important. For example, if something goes wrong, whether the decoration company is fully responsible for the warranty, or whether it is only responsible for the warranty of materials, or whether there are other restrictions, these should be clearly written in the contract.
Water and electricity costs: water, electricity, gas, etc. Will be used for decoration process and site construction. Generally, by the end of the project, the water and electricity charges add up to a lot, and who should pay this fee should also be indicated in the contract.
6. Construction according to the drawings: strictly follow the drawings signed and approved by you. If the details and dimensions are inconsistent with the design drawings, you can ask for rework.
7 Time and frequency of supervision and quality inspection: Generally, the decoration company will assign the project to each construction team to complete. Quality inspectors and supervisors are the most important means of supervision for decoration companies, and the interval of their inspections is particularly important for the quality of the project. Supervise the quality inspection and should be present every two days. The designer should also be present every 3-5 days to see if the site construction results are consistent with his own design.
To sign the renovation contract, we should grasp the following principles:
1 Talk about terms: All renovation contract have room for negotiation. You can talk as much as possible about your requirements for contract details. Only by persisting enough can we win more benefits.
2 Bargaining: Every designer has a certain discount right. In order to sign the bill, there will be an appropriate discount if you strongly demand it.
Model Contract: Please be sure to use the now-recognized 2004 revision of Beijing home decoration project construction contract, and click to view the contract.
Decoration reminder
Be sure to sign more supplementary terms.
1 Make a detailed list of the brands, specifications, prices and models of the main building materials involved in the renovation. For example:
Category, brand, specification and price
Macro board Peng Hong low formaldehyde macro board 1.22 * 2.44m 105 Yuan/piece.
List the unit price, total price and construction technology of each construction project. For example:
Technical practice of unit price and total price of unit quantity of engineering project
Brush the wall with 37 3 1 1 147 square meters, and brush the interface agent once, which makes the beautiful nest easy to scratch. Dulux's five-in-one second-generation grinding and painting uses sandpaper, and uses high-pressure airless spraying equipment to spray, with primer 1 time and topcoat twice.
3. Detailed construction drawings: indoor dimension drawings; Furniture layout; Hydropower transformation map; Schematic diagram of ceiling; The specific style of the door; Home details (such as elevation, section, detail node diagram of projects that need to be produced on site, such as TV background wall); The renderings of the overall home style, etc.
Ceramic tile procurement
How to choose tiles?
● Material selection:
1, polished tile: smooth and bright surface. 2. Vitrified brick: the surface is smooth and bright, but it is denser than polished brick and impermeable. 3. Mosaic: At present, the varieties and techniques of mosaics are gradually increasing, and high-quality glass mosaics are expensive, mostly in 300 yuan/square meter, which can be used for ornament. 4. Marble: It is used with caution in general families, and it is best to use it when it plays a role of local embellishment. 5, caulking agent: now the general household tiles, do not need white cement joint. Colorful caulking agents can sometimes bring unexpected results.
● General specifications:
The specifications of ceramic tiles are 400x400mm, 500x500mm, 600x600mm and 800 x 800 mm
Mosaic specifications are 20×20mm, 25×25mm and 30×30mm, and the thickness ranges from 4mm to 4.3mm in turn.
Price: From the price analysis, generally domestic glazed tiles, the price of first-class products is about 40 yuan per square meter, the price of dark glazed tiles is slightly higher than that of light glazed tiles, and the cost is about 80 yuan per square meter, plus auxiliary materials and labor costs. The price of imported glazed tiles is 1-3 times higher than that of domestic ones.
● Tile selection process
Step 1: Take a piece out of the box at will to see if the surface is smooth and intact. Glaze should be uniform, bright, without spots, lack of glaze, knock against, and the surrounding edges should be neat. Gloss, astringency, or bubbles in glaze are all quality problems.
Step 2: Take out another brick and align the two bricks. The smaller the gap, the better. If it is a pattern brick, it must be made up of four pieces into a complete pattern, and it is also necessary to look at whether the pattern of the brick is coherent and clear. Then take out all the bricks in a box and lay them flat on a big plane to see the overall effect from a little distance. No matter white, other colors or patterns, the colors should be the same. If some bricks are darker or lighter in color, they will look ugly and affect the overall decorative effect.
Step 3: Put these bricks up one by one and compare whether the bricks are the same size. The allowable deviation of small brick is ±65438±0mm, and that of large brick is 2 mm..
Step 4: Knock a brick against another brick, or knock a brick with other hard objects. If the sound of the brick is crisp and loud, it means that the quality of the brick is good and ripe. If the sound is abnormal, it means that the brick has double skin or cracks: double skin means that when the brick is formed, the air in the material is not exhausted, resulting in poor bonding between the materials and cracks inside, which can not be seen from the surface and can only be identified by listening to the sound.
School preparation
Make full preparations before construction.
After completing the property formalities, you can start the decoration.
1 Sign the renovation agreement issued by the property.
2. Provide drawings for self-decoration, mainly for water circuit reconstruction and demolition of non-bearing wall projects.
3. Get a "work permit", that is, the time limit for the property inspection posted on your doorstep.
Pass: mainly for workers to avoid illegal people from mixing into the community during renovation. (The charge for different communities is generally 15 yuan, and the cost is 5 yuan. The rest 10 yuan will be returned to the owner after renovation). When handling the pass, you'd better bring two one-inch photos of the foreman and workers who decorated you, and a copy of your ID card 1 copy.
5 renovation deposit (different communities charge different fees, at least about 2,000 yuan, which will generally be returned to the owner within 3 months after the renovation is completed).
6. Freight for garbage removal: This fee is used to pay for the garbage removal and decoration of the property, which is different from the fee paid to the decoration company. Generally, two people live around 300 yuan, and different property companies charge different fees.
Several things to do immediately after starting work:
1 list of building materials: ask the foreman in charge of decoration to show you a list of materials you need to buy and the time you need to send them to the site. Many decoration teams will tell you what kind of building materials they need the next day, only one day in advance. At this time, it is too late to ask for leave to buy.
2. Timetable: Find out the basic progress of the timetable, such as when the water circuit will be rebuilt, when the wood will be sealed, when the tiles will be attached, and when the ceiling keel will be made. In this way, you can arrange your time reasonably and go to the site regularly to check the quality of important steps.
3 Quality inspection time: If you know the time when quality inspection and supervision arrive at the site, you can arrange a time to go to the site together, so that once problems are found, they can be solved in time.
4 Avoid disputes: If problems are found in the construction, don't let the workers directly correct them. Even if you do, they may not change. You must talk to the quality inspector or the foreman. It will be useful. And it's best to write it down. In order to avoid disputes after renovation.
Decorative process
General process of pre-decoration
[1 Learn decoration knowledge]
Time: 2 months before renovation.
Methods: Consult more people with decoration experience.
[2] Visit the Building Materials City
Time: 65438+ 0 months before renovation.
Methods: Listen to the manufacturer's introduction and ask more questions.
[3] Determine the decoration budget and design ideas]
I have to have a general idea of how much it costs to decorate myself and what it looks like, and then I will contact the decoration company.
[4] Comparison of decoration companies
See more, listen more, compare more, and fully understand the level of decoration companies. It is recommended to consult about 3-4 decoration companies.
[5 Discuss the design scheme]
Good design should be dominated by your thoughts. Don't let the designer control it casually. Their starting point may be to make you spend more money.
[6] Confirm the quotation.
1 The contract is negotiable.
Quotations should be checked one by one, and everything you don't understand should be written clearly, so you can't muddle through.
[7] Choose a good construction team]
1 The level of the decoration team determines the quality of your home.
Be sure to see the construction site with your own eyes.
Write down the name of the foreman, and let this person lead the construction after signing the renovation contract.
[8] Signing a contract
1 Sign as many supplementary clauses as possible and write whatever comes to mind.
The contract shall be stamped with the official seal and notarized by the competent department.
[9 ready to start work]
1 Go through the formalities at the property office.
2. Pay the down payment for decoration.
[10 site disclosure]
The designer supervision foreman and the owner went to the site to check the information and explain the design and construction part.
[1 1 channel reconstruction wall demolition]
1 The renovation cost is high, and the renovation should be as little as possible on the premise of meeting the demand.
2 Non-load-bearing walls cannot be demolished.
[12 provisional acceptance]
1 Check the quality of carpentry, and it is best to ask an experienced friend to accompany you for acceptance.
2. Pay extra expenses for temporary projects.
[13 looking at furniture]
Time: After the renovation begins.
Methods: The designer's opinion must be consulted for furniture color matching [14 tiled kitchen and bathroom].
If it is an old house, it must be waterproof. The waterproof of the toilet shall not be less than1.8m..
The price of sticking small tiles is higher than that of ordinary tiles.
[15 Second Project Acceptance]
1 tile hollowing should be less than 5%.
2 ceiling keel to brush fire retardant coating.
3 waterproof to do 24-hour closed water test?
[16 finished door floor installation]
1 Floor Check whether there is enough floor in each package to prevent workers from stealing the floor.
The size of the door should be decided by the door manufacturer and the floor manufacturer to avoid inappropriate size.
[17 installing sanitary ware]
Try not to let workers use sanitary ware after installation.
[18 Installation of lighting hardware]
1 Multi-bulb lamps should be controlled in shunt, so as to ensure that only one group is turned on at a time, and it is not fully turned on, saving electricity.
2. The height of hardware installation must be tried in person for easy use.
[19 installing curtain cloth]
1 color and style of curtains, you'd better consult your designer.
Curtains themselves are not expensive, so merchants generally take advantage of the convenience of raising the price of dressings to make a profit [20].
1 Please accompany experienced people for acceptance.
2 Re-measure the area of all construction projects in person, so as to avoid the decoration company lying about the quantity.
[2 1 recovery and cleaning]
The cleaning cost of the 3-bedroom is around 150, which is collected by the well-known company 350 yuan.
Material method
First of all, we should do the following work:
1 Give the key to the construction unit.
Go to the scene to explain the situation: for example, where to add telephone lines.
Pay the down payment for decoration.
2. The following personnel must be present: designers, constructors and related technicians.
Three. Acceptance materials: on the first day of construction, generally only the large core board needs to be accepted. Remind you that it's 5 o'clock.
1 Whether it is a regular manufacturer's product. Check the manufacturer's trademark, production address, anti-counterfeiting logo, etc.
2 Whether the formaldehyde emission in the product test report is less than or equal to 1.5mg/l ..
3 See if the surface of the core board is smooth, warped, deformed, blistered and sunken.
4 whether the core strips are arranged evenly and neatly, the smaller the gap, the better, and whether the core strips are decayed, broken, wormholes and scars.
If the big core board emits a fragrant smell of wood, it means that the amount of formaldehyde released is less.
General decoration will encounter the following troubles:
Man-hour trap: Some irresponsible decoration companies often take the opportunity to delay the construction period in a passive and slack way, so that the amount of work that can be completed in one day can be completed in two or even three days.
Coping method: consult people with decoration experience, and estimate their own decoration time according to their own decoration process, and how many working hours a project will take to complete, so as to be aware of it.
Hydropower transformation
Renovation companies are the most profitable in hydropower transformation.
Water circuit transformation is the most important, but it is also the most important profit point for general decoration companies.
So when designing, we must strictly control the budget. General decoration companies will refuse to tell you in advance how much it will cost to transform water and electricity on the grounds that the specific figures of water circuit transformation should be based on the actual data on site, and it is difficult to estimate now.
As a result, when the owners check out, they often find themselves paying nearly three or four thousand yuan more for this project, which is very passive.
Countermeasures: Before signing the renovation contract, it is required to design and show the drawings of water circuit renovation, and strictly calculate the following items according to the drawings: telephone line renovation, power socket renovation, switch panel renovation, waterway renovation, cable TV line renovation and network cable renovation. And calculate the reasonable cost. This can avoid the high cost of extra items.
Matters needing attention in waterway reconstruction
1 PVC is a material prohibited by the state from being used as water pipes. Never use it. It is recommended to use copper pipes.
2. Underdrain: That is to say, all lines are hidden in the wall, and these need to be slotted on the wall to put the bushing of the line, which is more expensive.
3 open wire: it is to put the wire in the sleeve and hide it in the ceiling or under the floor tile, which is relatively cheap.
4 Waterway design should first think about all water-related equipment, such as water purifier, water heater, kitchen treasure, toilet, washbasin, their location, installation method and whether hot water is needed.
Except the water outlet of washbasin, toilet, washing machine, etc. It is best to take one out of the bathroom to mop the floor after receiving water.
It is best not to seal the floor drain of the washing machine with deep water, because the water flow is too slow to meet the needs of the washing machine.
7 Strong and weak wires cannot be in the same pipeline, which will cause interference.
concealed work
Concealed engineering can not be ignored.
1 wooden keel
Wooden keel should be used for heating cabinets, suspended ceilings and solid wood floors. The key is to put an end to inferior wood. In addition, in order to prevent fire, the wooden keel should be painted with fire retardant coating 1-2 times. Small decoration companies often cut corners in this respect.
2 Ground waterproofing
Pay attention to waterproof ground. At present, the commonly used waterproof materials are: polyurethane coating; Water does not leak; After waterproof treatment, the plugging agent should be tested for water storage to see if there is water leakage within 24 hours.
3 Don't close the pipeline.
Don't seal waterway pipes in partitions or cabinets for the sake of beauty. Be sure to reserve the manhole, or you won't be able to open the manhole, and you will suffer.
4 Buried wires must be sheathed.
Buried wires cannot be directly buried in the wall, but should be covered outside the wires. The wires in the sleeve shall not be twisted or jointed. Otherwise, there will be no way to repair and replace the aging wires in the future.
Don't sign the decoration easily.
Generally, the decoration company will ask you to sign the acceptance sheet after the concealed works are accepted, but you should be careful that this word is not signed casually:
1 Check carefully whether the added items are completed, whether the quality is qualified, whether the size is correct, and whether the size and quantity on the budget sheet are completely consistent.
Believe in yourself: as long as any project is completed, you should personally check the area. You must not be lazy at this time. You know, even if a room has an extra square meter of wall paint area, it costs more than 30 yuan.
Never believe the foreman telling you, "This thing is like this, you don't understand, it's not a quality problem." Be careful at this time and ask more experienced friends, often the trap is here.
ceramic tile
Pay attention to waterproofing before tiling.
Personnel: generally, 1-2 bricklayers are needed.
Sequence: Stick the wall tiles first, and then stick the floor tiles.
Time: Good bricklayers paste 5-6 square meters a day, otherwise the quality is difficult to guarantee. Especially in places where small diagonal angles are needed, such as window sills, it takes a lot of time.
1, colored glazed tile:
Basic treatment → elastic line → brick wetting → cement mortar laying → standard block installation → floor tile laying → jointing → cleaning and maintenance.
2, the shop is stuck ceramic mosaic (mosaic) class:
Basic treatment → elastic line and standard reinforcement → spreading cement mortar → paving → compaction → sprinkling water, uncovering paper → sealing → cleaning → maintenance.
Key points of ceramic floor tile construction.
1, concrete ground base should be chiseled, the depth of chiseling is 5~ 10 mm, and the spacing of chiseling marks is about 30 mm. After that, clean up floating ash, mortar and oil stains, and brush the ground with aproll.
2, before the shop is stuck, should play good line, pop up on the ground at right angles to the door of the baseline, play line should start from the door, to ensure that the door for the whole brick, rather than the whole brick under the internal angle or furniture, play line should pop up vertical and horizontal positioning control line.
3, before the shop is stuck ceramic floor tile, ceramic floor tile should be soaked in air to dry.
4, when the shop is stuck, the back of the ceramic floor tile should be covered with cement mortar, and after the shop is stuck, it should be tamped with rubber pestle. At the same time, check and correct with a level, and plaster cement mortar.
5. After paving for 2-3 hours, wipe the joints with white cement, and use cement mortar, cement and sand = 1: 1 (volume ratio). Joints should be tightly filled and smooth. Then wipe the surface with cotton silk.
final acceptance of construction
final acceptance of construction
1. Wall surface: the flatness of the wall surface affects the aesthetic degree, and the uneven wall surface is easy to crack. The owner can check with the naked eye or ruler.
2. Circuit: Take a small electrical appliance with you, such as a mobile phone charger, and try all sockets.
3. Waterway: Flush the toilet several times to see if the running water is smooth. Fill the bucket with water and pour it on the ground to see if the floor drain is unobstructed. Try all faucets, whether they are flexible or not. If you have a water heater at home, be sure to try to see if the hot and cold water are connected backwards.
4. Wood: The most important thing is to check whether there is a pungent smell.
5. Tiles: Knock with a small hammer to see if there are empty drums, whether the gaps are full and whether the tiles are flat.
6, the floor: whether the parquet of the floor is neat, the feet feel comfortable when stepping on it, and there is no abnormal sound. There should be no excess glue on the floor-this is very important, otherwise it will be difficult to clean it up later.
