Two quotes for the same job can look very different, and the cheapest one isn't always the best deal. Here's how to read a construction quote properly and compare like with like.
What a good quote includes
- Your name and the job address
- A clear description of the work, like "Build 12 ft by 10 ft extension, 6-inch block walls, concrete slab roof"
- Materials, listed line by line with quantities and prices
- Labour, either per item or as a total
- Equipment and transport, like trucking or mixer rental
- What's not included
- The total price, and whether GCT is included
- Payment terms and the deposit needed
- How long the price is valid
- The start date and how long the job will take
Questions to ask
- Are quantities realistic? Check the number of blocks, bags of cement and steel against a material calculator. Very low quantities can mean extras later.
- What grade of materials? Steel size, block size and roofing type all affect the price.
- Is clean-up included? Removing rubble costs money.
- Who pays for approvals and inspections?
- What happens if prices change? Material costs move, so agree how increases will be handled.
Compare quotes fairly
Put the quotes side by side and compare each line. A cheaper quote might:
- Leave out items the others include, like plastering, painting or electrical work
- Use smaller steel or thinner materials
- Count fewer labour days than the job really needs
When you ask each contractor to price the same list, it's much easier to see the real difference.
Red flags
- A single total with no breakdown
- No mention of what's excluded
- A price that's far below the others
- Pressure to sign today
Before you sign
- Make sure every change you discussed is written in.
- Agree the payment stages.
- Keep a signed copy for yourself.
