Worst contractor I have ever used for anything on my house. Please get everything in writing with these guys and take a lot of pictures. Currently they are not done with the system and have sent a 14day lien letter to me. They have a warranty but will they even be around to honor it.
Update one: had to remove a review that was brought to the attention of YELP by the community....currently waiting for the owner to get back to me as to what and when they can finish. Current contract is 8months old. Please be very careful and don't throw away any document with this contractor.
Update: all done
