Why Two Renovation Quotes Can Have Such Different Prices

Getting two renovation quotations for the same home can sometimes leave homeowners confused.
One contractor quotes $20,000, while another quotes $35,000.
Both seem to be offering the same renovation scope. So why is there such a big difference?
The answer is that renovation quotations are not always comparing the same things.
A lower quotation does not automatically mean a better deal, just as a higher quotation does not automatically mean better quality.
Before comparing prices, homeowners need to understand what is actually included in each quotation.
1. The Scope of Work May Be Different
The biggest reason for price differences is often the scope.
For example, one quotation may include:
Hacking
Disposal
Plumbing
Electrical works
Painting
Carpentry
Installation
While another may only include selected items.
Two quotations can look similar at first glance but contain very different levels of work.
Always ask:
"What exactly is included in this price?"
2. Different Materials Can Have Very Different Costs
The same-looking cabinet can be made using very different materials.
For example, a quotation may specify:
Different board types
Different laminate brands
Different thicknesses
Different edge finishing
Different hardware
Even when the final design looks similar, the material specifications can affect both price and durability.
This is especially important when comparing carpentry quotations.
3. Hardware Can Affect the Price
Cabinet hardware is another area where quotations can differ significantly.
For example:
Standard hinges vs soft-closing hinges
Standard runners vs premium soft-closing runners
Basic drawers vs heavy-duty drawers
Standard storage vs specialised pull-out systems
Hardware may not be the first thing you notice when looking at a cabinet, but you use it every day.
4. Carpentry Pricing May Not Be Based on the Same Specifications
A quotation saying "10ft wardrobe" doesn't tell you everything.
You should also check:
Height
Depth
Number of doors
Internal compartments
Drawer quantity
Material
Laminate finish
Hardware
Installation
A full-height wardrobe with multiple drawers and premium hardware will naturally cost more than a basic wardrobe of the same width.

5. Different Contractors Have Different Business Structures
How a renovation company operates can also affect pricing.
Some companies may work with multiple layers of subcontractors and suppliers.
Others may have more work handled directly through their own teams or facilities.
Each business structure has different operating costs, which can be reflected in the final quotation.
This is why homeowners should understand who is actually carrying out the work rather than comparing only the final number.
6. Design Fees and Professional Services
Some renovation quotations include additional professional services such as:
Detailed design work
3D visualisation
Site coordination
Project management
Technical drawings
Revision support
Other quotations may offer a more basic service.
If these services are not clearly listed, homeowners may assume both quotations provide the same level of support when they don't.
7. Installation and Labour May Be Different
A quotation may look cheaper because certain installation work is excluded.
For example:
Cabinet installation
Lighting installation
Sanitary fitting installation
Mirror installation
Appliance installation
Always check whether the quoted price includes delivery, installation, and final adjustment.
8. Hacking and Disposal Are Easy to Overlook
If you're renovating an existing HDB or condo, don't forget about demolition.
Costs may include:
Tile hacking
Cabinet removal
Wall hacking
Debris disposal
Transportation
A quotation that excludes these items may initially look much cheaper.
Once the additional work is added later, the final price can be very different.
9. Renovation Site Conditions Can Affect the Cost
Not every home is the same.
Even two units with similar layouts can have different site conditions.
For example:
Uneven walls
Existing pipe locations
Electrical limitations
Structural restrictions
Difficult access
Existing damage
These factors can affect the amount of work required.
10. Cheap Quotes Can Sometimes Lead to Variation Costs
One of the biggest concerns homeowners have is receiving a low initial quotation and then facing additional costs during the renovation.
Variation costs may come from:
Changes requested by the homeowner
Previously excluded work
Site conditions
Material upgrades
Additional electrical points
Additional carpentry
This doesn't mean every low quotation is problematic.
The important thing is to understand what is included before signing.
11. A Higher Quote Isn't Automatically Better
It works both ways.
A higher quotation doesn't automatically mean:
Better workmanship
Better materials
Better service
Better project management
Some homeowners assume that spending more guarantees better results.
It doesn't.
The important question is:
What are you actually getting for the additional money?
12. Compare Quotations Line by Line
Instead of comparing:
Contractor A: $25,000Contractor B: $32,000
compare the actual scope.
For example:
Item | Contractor A | Contractor B |
Kitchen cabinets | Included | Included |
Cabinet material | ? | ? |
Hardware | ? | ? |
Countertop | ? | ? |
Hacking | ? | ? |
Disposal | ? | ? |
Electrical | ? | ? |
Plumbing | ? | ? |
Painting | ? | ? |
Installation | ? | ? |
Once you compare the details, the price difference may become much easier to understand.
13. Ask These Questions Before Choosing
Before accepting a renovation quotation, ask:
What materials are being used?
Don't settle for vague descriptions such as "good quality material."
Ask for the actual specifications.
What is included and excluded?
Make sure you know exactly what you're paying for.
Are delivery and installation included?
This is particularly important for carpentry.
What happens if there are changes?
Ask how variation works before the renovation begins.
Who is doing the work?
Understanding whether work is handled in-house or outsourced can help you understand how the project is managed.
14. Look at Value, Not Just Price
The cheapest quotation may not provide the best value.
For example:
$25,000 quotation + $8,000 in additional works = $33,000
could ultimately cost more than:
$30,000 quotation with a clearer and more complete scope.
That's why homeowners should compare value and scope, not just the starting price.
Final Thoughts
Getting multiple renovation quotations is a smart idea — but comparing only the final price isn't enough.
A $20,000 quotation and a $35,000 quotation may look completely different once you compare:
Materials
Workmanship
Hardware
Scope
Installation
Project management
Inclusions and exclusions
Before choosing a contractor, make sure you understand what you're actually paying for.
Because the cheapest renovation quote isn't necessarily the cheapest renovation in the end.
And the most expensive quote isn't automatically the best.
The best quotation is one that gives you clear scope, transparent pricing, suitable materials, and confidence in the team delivering the work.
