"I choice Randazzo Masonry for a quote and he call me right back with an estimate and came that afternoon to view the work I wanted done. He is very personable and explain what was involved. I accepted his estimate and he completed the job the next day. He worked quickly and make sure he follow my wishes to my satisfaction. The job was simple as I wanted a concrete slab to accommodate my central AC component."

"Retaining Walls and Driveway with Pavers. I hired the Napolitano Brothers to build a massive retaining wall in my backyard. They also completed a 95 foot driveway with pavers and Belgium block. They did a phenomenal job! They were very professional and committed to their work. I could not have been more pleased with the finished project. Their design sense was also exceptional. When people come into my home they gravitate to the back door and look upon my yard in awe. Thank you for what you created! I highly recommend them. They were also very fairly priced."

"Gerard (aka Promaster Maintenance Corp) and his crew did a fantastic job on my really long driveway. They laid over 1,700 square feet of asphalt. They reset the existing Belgium blocks and cemented them in place in a perfect straight line and the Belgium blocks on the front of the driveway has already received raves from our neighbors. His crew is polite, hard working and they did a good clean up job after every work session. Gerard was determined to make us happy and made every adjustment we requested. He offers his professional opinion to make the job right. His pricing is competitive and there were no â hiddenâ surprise charges. Would I hire Gerard and his team again â YES."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."
