A flooring contractor can provide a ballpark estimate during a project’s specification stage. But providing a hard quote for the actual cost is like predicting the score of a game when the first pitch is thrown. Sure, player stats and team standings may be good indicators, but how any one game plays out can leave us in suspense until the bottom of the ninth. And so it is with floor preparation estimates. Every job is unique. Even with the benefit of a long experience curve, estimating involves a bit of a guestimating until the job is actually underway. This issue of Starlog will focus on subfloor preparation issues and floor installation estimates, which go together hand-in-glove.
