It's only after assessing and diagnosing the nature and extent of the problem it is possible to determine an exact price and give a quote. Unfortunately, most firms are reluctant to provide an estimate. Some also use various contingencies to justify any price changes after it's quoted. Unless there is the chance of some unforeseen conditions requiring additional workforce or drain cleaning equipment, the prices should remain intact. It's reasonable for a price change if some additional equipment is needed because of a change in the reported condition. You only pay the quote, and any mutually approved upon changes, while dealing with Dima Plumbing, your affordable plumbers in Toronto and GTA area.
