Are you comparing the same job?
Two polished concrete quotes are only comparable when both say what is included. Tick what is written in the one in front of you and see what is not.
Tick what the quote actually says
Not what you were told on the phone. What is written on the page in front of you. Leave anything vague unticked, because vague is the same as missing once there is a disagreement.
Still the same rule
This works from what you tell it. Your slab gets the final say, and that needs someone standing on it. Send photos and we will price the actual job.
