The crews are so polite, efficient, and good at their jobs. We had two different crews for set up and take down, and were impressed both times. They do a great job hanging the lights and they make sure that you get exactly what you want. Everything looks perfect when they are done. The company uses high quality, commercial grade bulbs and wires that are custom cut to fit without excess cords running everywhere. It was such a clean, perfect look compared to what I’ve seen at other weddings. They can be a bit pricey, especially if you have them hand wrap full trees, but everything looks so perfect when they are done, and the convenience factor of not dealing with it is well worth it to my husband and I. We are very happy with Sierra Lighting and highly recommend them.
