Last month, my client Mandy just bought a 400-square-foot second-hand unit and excitedly approached three renovation companies for quotes. When the three quotes were laid out, she was completely shocked—although it was all for 'full-house renovation,' the quotes differed by more than 200,000! The most outrageous part was that the unit prices for some items differed by more than three times. She asked me, 'Which items are most likely to be overpriced? How can I avoid getting tricked?'
This problem is encountered by almost every homeowner preparing for renovation. According to data from the Consumer Council in 2023, over 60% of renovation dispute cases involved 'unclear quotations' or 'additional charges.' Today, I will use my 15 years of experience as a real estate and renovation consultant to break down the renovation items that companies most often 'overestimate,' and teach you how to smartly review quotations to avoid being taken advantage of.
The Five Renovation Items Most Often Priced Exorbitantly
1. Water and Electricity Engineering: The Area with the Most Hidden Issues
Electrical and plumbing work is the project in renovations most susceptible to 'inflated estimates,' because most of the work is carried out inside the walls, and the homeowners cannot directly monitor the materials and processes.
:::warning Common Pitfalls:
- The 'rewiring of the entire house' actually only replaced some of the wiring.
- Using ordinary wires as 'international brand wires'
- Faucet fittings are of inferior quality but sold as if they were good, charging for Japanese products while using domestic goods.
- "Charging by points" but not clearly explaining the definition of a 'point'
:::
Market Reasonable Price Reference:
- Rewiring the entire house (400 sq ft unit): $25,000 - $35,000
- Replacing the distribution box: $3,500 - $5,500
- Adding a power socket (each): $800 - $1,200
- Re-piping the entire house: $18,000 - $28,000
:::tip Expert Advice: It is recommended to request the renovation company to specify the brand of electrical wires (such as Belden, Nexans), wire gauge specifications (such as 2.5mm²), and plumbing brands (such as Geberit, Wavin) on the quotation. If the quotation only uses vague terms like 'high-quality wires' or 'imported plumbing,' there is definitely a problem. :::
2. Custom Furniture: The Most Complex Item in Pricing Methods
Custom-made furniture is another heavily affected area for 'inflated numbers.' Many renovation companies quote prices based on 'per square foot,' but the actual calculation methods vary greatly, making it difficult for homeowners to compare.
Three Common Pricing Traps:
- Projected Area vs. Developed Area: Some companies calculate using the "projected area" (i.e., the cabinet's length × height), but the actual charge is based on the "developed area" (the total area of all panels when laid out), with a difference of 2-3 times.
- Hardware accessories are charged separately: The quotation shows "$800/ft", which seems cheap, but all hardware accessories like hinges, tracks, and handles are charged separately, so the final total price may be more expensive than a quotation of "$1,200/ft all-inclusive".
- Cutting corners on board thickness: The quote states "18mm plywood," but in reality 15mm or even 12mm is used, which most homeowners can't even tell.
:::highlight Insider Tip: Request the renovation company to provide a quotation for the 'expanded area' and indicate on the quotation:
- Sheet material brand and thickness (e.g., '18mm Austrian Egger board')
- Hardware brands (such as 'Blum hinges', 'Hettich slides')
- Does it include all hardware accessories?
- Does the cabinet have a back panel (some companies omit the back panel to reduce costs)?
:::
Market Reasonable Price Reference (calculated by exposed area):
- Ordinary Plywood Cabinet: $180 - $250/ft²
- Moisture-Proof Board Cabinet: $220 - $300/ft²
- Solid Wood Cabinet: $350 - $500/ft²
3. Painting Project: The Item with the Greatest Difference in Materials
Painting work may seem simple, but in reality, it is one of the easiest projects to cut corners on. Even when it comes to "painting the entire house," the differences in materials and processes can be very significant.
Common Methods of 'Exaggerating Numbers':
- Using inferior paint brands: The quote says 'ICI Paint,' but they actually use generic brands or the lowest-grade ICI products.
- Reducing the number of paint layers: The standard should be 'one undercoat and two topcoats,' but some workers only do 'one undercoat and one topcoat,' or even 'two topcoats without an undercoat.'
- Insufficient wall preparation: Skipping processes like putty and sanding, resulting in poor paint results.
:::success How to Ensure Paint Quality:
- Specify the paint brand and model on the quotation (e.g., 'Dulux Diamond Matt')
- Indicate the number of paint layers (e.g., 'one coat of primer and two topcoats')
- Require keeping the paint can as evidence
- Personally be on-site to supervise and ensure that the workers are following the standard procedures.
:::
Market Reasonable Price Reference (400 sq. ft. unit):
- Full house painting (including putty and sanding): $12,000 - $18,000
- Painting only (excluding putty): $8,000 - $12,000
- Feature wall (such as chalkboard paint, magnetic paint): $150 - $250/sq. ft.
4. Masonry Work: The Item Most Likely to Incur Additional Costs
Masonry and plastering work is the item in renovation that is most likely to incur 'additional costs,' because many problems are only discovered after demolition.
Common Additional Fee Traps:
- 'Problems discovered after demolition': Issues such as water leakage or exposed rebar are only mentioned after walls are torn down, requiring additional charges to address.
- Floor leveling requires extra cost: Not mentioned in the quotation, only during construction is it stated that uneven floors need extra payment.
- Waterproofing is charged separately: The quotation only states 'tile laying,' but the waterproof layer is charged additionally.
:::warning Pitfall Avoidance Guide:
- Request the renovation company to conduct a 'building inspection' before quoting, to assess the condition of the unit.
- Stated in the contract 'includes all foreseeable additional works'
- If an unexpected situation really occurs that requires additional costs, request photographic evidence and a reasonable quote.
- Waterproofing works must be specified in the quotation, including the thickness and brand of the waterproof layer.
:::
Market Reasonable Price Reference:
- Removing old tiles and laying new tiles (including labor and materials): $180 - $280/sq.ft
- Waterproofing works: $80 - $150/sq.ft
- Floor leveling: $50 - $100/sq.ft
5. Sanitary Ware and Kitchenware: Items with the Biggest Brand Differences
The brands and models of sanitary ware and kitchenware vary greatly, and prices can differ by several times, making them one of the easiest items to 'inflate numbers' on.
Common Pitfalls:
- Using lower-end models as high-end goods: Different series of the same brand can differ in price by more than double
- 'Installation included' actually only covers basic installation: Additional accessories, relocation, lengthening hoses, etc., are all charged separately
- Using domestic products as imported goods: Especially for faucets, showers, and other accessories
:::tip Smart homeowners must do their homework:
- Request the renovation company to provide the brand, model, and origin of the sanitary ware and kitchen appliances.
- Check the market price of that model online by yourself
- Consider buying sanitary ware and kitchenware yourself, and only pay the installation fee to the renovation company
- Keep all product packaging and manuals, and confirm whether they match the quotation.
:::
Market Reasonable Price Reference:
- Toilet (including installation): $2,500 - $8,000
- Washbasin with faucet (including installation): $2,000 - $6,000
- Shower set (including installation): $1,500 - $5,000
- Kitchen cabinet (including labor and materials): $1,500 - $3,500/ft²
How to Review a Renovation Quotation: Five Key Checkpoints
Checkpoint 1: Is the quotation detailed enough?
A qualified quotation should clearly list the following for each item:
- Description of the work
- Brand and specifications of materials
- Unit of measurement (e.g., "sq ft", "meter", "item")
- Unit price and total price
- Whether it includes hardware accessories, transportation fees, cleaning fees, etc.
:::warning If the quotation only has a vague description like 'Full house renovation $300,000,' it is absolutely unacceptable. Such a quotation has a very high chance of additional charges later on. :::
Checkpoint 2: Are there any 'hidden fees'?
Common hidden charges include:
- Management fees (usually 5-10% of the total price)
- Cleaning fees
- Garbage disposal fees
- Dump truck fees
- Upstairs fees (if there is no elevator)
- Protection project fees (for protecting floors, elevators, etc.)
Expert Advice: Request that the renovation company provide a budget cap for 'actual cost reimbursement' items to avoid unlimited additional charges in the future.
Checkpoint 3: Are the payment terms reasonable?
Reasonable payment terms should be:
- Deposit: 10-20%
- Mid-term payment: 30-40% (after completion of demolition and electrical and plumbing works)
- Final payment: 40-50% (after project completion and inspection)
:::warning Danger Signal:
- Require a deposit of more than 30% from the beginning
- The progress requirements for each payment period are not clearly specified.
- The final payment is less than 30% (which means you do not have enough bargaining power)
:::
Checkpoint 4: Warranty Period and Coverage
A legitimate renovation company should provide at least a one-year warranty and clearly specify the scope of the warranty.
Essential Maintenance Items:
- Plumbing and Electrical Works (issues such as water leakage, electric leakage, etc.)
- Painting Works (issues such as peeling, discoloration, etc.)
- Custom-made Furniture (issues such as hardware damage, board deformation, etc.)
- Masonry Works (issues such as hollow bricks, cracking, etc.)
Checkpoint 5: Compare quotes from at least three companies
Don't just look at the total price; compare the unit price and materials of each item individually. Sometimes the quote with the lowest total price actually uses the worst materials, resulting in the highest additional costs later on.
:::success The Correct Way to Compare Quotes:
- Align the items of the three quotations one by one
- Compare the brands and specifications of materials for the same items
- Calculate the unit price of each item (such as 'per square foot', 'per meter')
- Pay attention to which items are not included in the quotation
- Inquire about each company's handling of 'accidental situations' and their charging standards.

Real Case: How to Avoid Being 'Overcharged'
Case 1: The "International Brand" Trap in Water and Electricity Engineering
My client Tommy received a quotation that stated 'Rewire the entire house with international brand wires, $45,000.' He thought the price was reasonable and signed the contract. However, during construction, it was discovered that the workers were using domestic generic brand wires, not some 'international brand' at all.
Tommy immediately requested the renovation company to replace it, but the other party said, 'We use internationally certified wires that meet Hong Kong standards, there’s no problem.' Tommy was speechless because the contract indeed did not specify a particular brand.
Lesson: Be sure to specify the exact brand and model on the quotation and contract; do not accept vague terms such as 'international brand' or 'high-quality materials'.
Case 2: The "Projected Area" Trap in Custom Furniture
My client Sarah received a quotation that said 'Custom wardrobe $800/ft'. She thought the price was very cheap, so she signed the contract. After completion, however, the renovation company issued a bill of $60,000, which was twice as much as her expected $30,000!
It turns out that the "$800/sq ft" on the quotation refers to the "projected area" (the length × height of the wardrobe), but the actual charge is calculated based on the "unfolded area" (the total area of all the boards laid out). Sarah's wardrobe has a projected area of 37 sq ft, but the unfolded area reaches 75 sq ft!
Lesson: Be sure to ask clearly whether the quotation is calculated based on 'projected area' or 'unfolded area,' and request that it be specified in the contract.
Case 3: The 'One Coat, Two Sides' Trap in Painting Projects
After the unit of my client Michael was painted, he found that there were many flaws on the walls and the color was uneven. He questioned the renovation company, but they said, 'Your quote did not specify that you wanted "one coat on the primer and two topcoats." We have done "two coats" already, which is good enough.'
Michael checked the quotation and found that it indeed only stated 'whole house painting,' without specifying the number of paint layers. As a result, he had to pay an additional $8,000 to redo it as 'one coat and two finish coats.'
Lesson: For painting projects, the number of paint coats (such as 'one undercoat and two topcoats'), brand, and model must be specified on the quotation.
Summary: A Checklist for Smart Homeowners to Review Renovation Quotes
