I highly recommend Sergio and his crew. More than 12 years ago I bought a 105 year old, 6 unit building on the north side. It is my main investment for my retirement. About 4 years after I purchased the building I began to notice my brick "spalling" with chips of brick accumulating on the ground around my building. I also noticed loose bricks and water accumulating under my roof around the edge of my building. I desperately began asking everyone in the trades what was wrong. I had many masons give me their assessments and their estimates, some of which came to hundreds of thousands of dollars. I hired three different masons to do work they assured me would stop the "spalling" and the water accumualtion. This work cost a few thousand and had absolutely no effect. Finally Sergio was recommended to me by another tradesman whose work I admired. Knowledge applied with intelligence is essential in the maintenance of an old building, and that is what Sergio brings to the table. He diagnosed what would be the most reasonable solution to stop my brick from deteriorating, which was rebuilding my parapets. Sure, this is not a cheap proposition, but it was way less than some of the extreme solutions proposed to me and I checked his prices and was told they were standard for good work. So far it has worked and it has been almost 2 years. Sergio has the integrity to do all the work according to the best standards. He explains every step and he stands behind his work. The work is done in a timely and professional manner. You will not have to tolerate work being started and then left there for weeks without being completed, or people who show up late in the day and only work for a few hours, or any of the other lack of professionalism we often have to tolerate from the trades. Sergio and his crew are consummate professionals. Lastly, let me say that many women are now property owners, and if you are tired of being cheated or treated like you are stupid, you will not have to tolerate that from Sergio. read more
