Whats the difference between a Quotation and an Estimate?
Always try to obtain a Quotation. This is a fixed price and, as such, prevents yourself from any further expense; with an Estimate the person you employ is legitimately able to ask for more money for work they have done, and, believe me, a lot of them will find a reason to up the price! An experienced Arborist should know how long a job will take, and can therefore supply a Quotation rather than an Estimate as all the work is visible to the eye.
