Very satisfied. Russell replied to our job within the day we posted it and came the day after (during weekend) to check it. He had a look at our issue which was an easy fix; and advised us on how to avoid it and explained us how to maintain our windows. As it was an easy job that took about 5mn, he didn't even charge us for coming to check and advice. He was very pleasant and professional, and very keen on advising us. We will definitely keep his contact for future needs.
