Report
The whole process was highly organized and professional, from selecting and ordering to scheduling and installing our new SunSetter awning. The representative who visited for measurements and provided a quote was extremely knowledgeable. The installation team was very meticulous, paying close attention to every detail, including concealing the wire from the motorized awning to the outlet. Even when looking closely, the wire was virtually invisible. Overall, we were extremely satisfied and highly recommend their services.

Report
The two individuals who installed my awning did a good job initially. They were originally supposed to hang it under the house, but they were unable to do so, and instead, they attached it to the side of the wall. They did a very good job, and I am pleased with the result. The awning looks really great in its current position, and I am happy with how it turned out.
