Absolutely no complaints. They quoted me a price which was 1000 dollars less than every other reputable outfit quoted me, showed up on time, and completed the job in the time they claimed they would.
The job was thoroughly looked over by Salvador, myself, and later by his brother for completeness. The workers were friendly and professional. Salvador also threw in two extras in the job, a lead flashing for my electrical mast, and an extra (needed) vent in my garage, no extra charge!
I would absolutely recommend them based on my experience.
