Quality … The Install Is Important
It is obviously important to compare apples to apples when comparing stone masons. Don’t compare ceramic tile installers with stone masons. They both have great skill sets but its like asking a square peg to fit in a round hole.
Be careful that your estimate spells out the specific stone, thickness and finish. Lead times are extremely important. Insure your mason is familiar with local zoning codes. Ask him or her for links to their portfolio or web site of completed work. Finally, show him or her photos of what you like so you are both on same page from a design intent standpoint.
