Quotes are more exact than estimates
An estimate is roughly how much the tradesperson or professional thinks the job will cost. They must use their skill and experience to make the estimate. The actual price may be more or less, but it shouldn’t be too much more – it should be within 10 to 15 percent.
A quote is an offer to do a job for an exact price. If you accept the quote, the contractor can’t charge you more than the agreed price. Make sure the quote states if it includes GST. Since the cost of materials and hourly rates changes over time, the quote will only be valid for a certain time period.
