John and the owners son showed up this morning at 10, it's 7pm and they are still in my driveway as I am typing . To say they did an efficient job is an understatement. They went above and beyond to make sure the job they were facing today in our home was done correctly. They did not stop for lunch which is really bothering me due that I should have made these gentleman a hot meal. Thank you Thorsen's for having excellent employees, I am truly relieved!
