My upstairs floor was so unstable that carpets would not stay flat, and the floor felt spongy. Jim consulted with me at my house and then talked to his carpentry crew. They decided to take out the ceiling downstairs and assess the foundational beams. They found dry rot and many broken beams. They sistered all the beams and tested the strength of the floor; then sistered some more until the floor above was no longer spongy. (The span was too great for the foundation that had been built.) The carpenter also checked out the beams holding up the room they were working in and I asked to have him firm up a major beam and one that had been cut to make room for the furnace. The guys put up new drywall and ceiling moulding, another worker came out and beautifully finished the drywall, and yet another came and painted. Jim came out several times and repaired a problematic light switch while he was there. Jim lined up the workmen so the job was done as quickly as possible, and after the painter finished the ceiling, Jim put up a ceiling fan. I have no yard so the carpenters took the trash with them at the end of the day, sparing me the cost of a rental. Everyone was intelligent, polite, and responsible. I am very particular, about drywall work especially, and was very pleased with everything. Except for the additional work done in the basement which I asked to add to the job, the estimate was right on. (I was not at all pressured to do the basement work; I was impressed at the carpenter's assessment and plan and asked him to include it in the job rather than come out another time.) Both the carpenter and the drywall finisher were perfectionists and it showed. I was on site the whole time. The ceiling, moulding, and new fan have made the room look so good that I am repainting it and preparing upstairs to install new carpet. Jim was not only professional and courteous, he was amiable and a pleasure to work with.
