An estimate (can be verbal or written) is a calculation of what the service provider thinks the work is likely to cost. It indicates the nearest price, or a range of prices expected, based on past experience. It is not a firm offer to do work for the stated price, but it should provide you with a reasonable idea of what the work will cost. If you want a definite price, you should follow up by getting a quote.
A service provider can charge a fee for preparing an estimate, as long as they tell you first.
Tip:   It’s a good idea to shop around and ask for quotes from different businesses. This will give you a good idea of what the average price is for the service you are looking for. Asking for references from former clients or searching reviews online can also help you decide on the service provider.
