Alan and his colleague did a great job. They were on time and took the time to explain what they did. They also opened up blocked air flow at the rear of the attic and advised that we should get someone to unblock air flow at the front of the attic. They noticed a fan air pipe that was disconnected and fixed it and did not ask for more money. They worked hard and were both very nice and professional. I had requested a few quotes and their price was very competitive and fair. I also felt that Alan was very honest. Would happily recommend.
