I would rate this a 4, but it took 2 trips because the crew didn't have all of the materials on the truck to complete the work order the first time. The materials were not staged for the project, and it ended up causing me to take another day off work to be present.
The lift crew did a great job and explained what they were doing. the crack seal was not well done, didn't look good and my impression was I should have done it myself considering the expense.
The process was something I decided I might go with based on researching what methods and products are available, and my past experiences. The rep did a great job explaining things and following up.
