It was my first time employing Twin Home Experts and they did some good work for me but it was so recent that I am hesitant to give them 5 stars till I see if everything holds up. They are good people and very easy to work with because they are very skilled in their field. The installation went very smoothly, they were able to install the unit with no problems at all but after they left I noticed a small rattling noise so I had to call them back but they were able to square things away very quickly for me. They are very busy but they communicated very well to make sure we were happy throughout the whole process.
