We had been happy with the service before and decided to call United again. They were very prompt in coming to give us an estimate and set a date for the work to be done. The man who came to assess was friendly and explained everything and came up with a solution to our problems with water in the basement that sounded great. When the date came and the workers started to drill, cement started to fall from the ceiling in the basement. They immediately stopped work. It turned out the there was a portion of the basement ceiling that was not stable. They cleaned everything up, and the owner, Giovanni, got involved right away. He came personally to look at the house, and proposed a slightly different solution which was a little more complicated as the situation was a little different than had been originally assessed. We were very happy with the result and the new work was super promptly done, Giovanni came to oversee it all himself, and it seems great so far (we are waiting for a very heavy rainfall to truly see how it goes, but it looks perfect. It just hasn't been fully tested yet :)) What struck me most of all was the sincere care from Giovanni and the fact that he stood by the original estimate, when the work that was actually done was more complicated and likely cost more for them to complete.
