I called United based on many, many recommendations. Isela could not have been more kind and helped arrange a n appointment with my challenging schedule despite them being so busy. Giovanni, the owner of United, made time to come see me himself and was able to diagnose and fix the sump pump in 20 min!! And he stayed to show me what was broken and how it now worked beautifully. It was humming and working perfectly now, thanks to Giovanni! Giovanni was a complete gentleman, so kind and helpful, patient, and genuine! I will need more waterproofing, and I will surely use United!! Professional, caring, understanding, honest, and exceedingly reasonable!!

This is a tough review to write, because the crew (Nick & Elario) were outstanding; they were professional, friendly, and their work was excellent. They exceeded my expectations -- outstanding work! This would be a 5-star review, EXCEPT -- the communication from the company is terrible. They don't answer the phones, they don't answer emails, they don't return phone calls or reply to emails. They are extremely frustrating to deal with. Interestingly, if you call in the evening when the local office is closed, Groundworks Canada answers the call, and actually does their best to help. But the South Plainfield office, fuggedaboudit. But let me end by saying, the work they do lifting concrete is outstanding. Too bad they have such a dysfunctional administrative office.

It's been almost 7 months since Nick and his team repaired and waterproofed the outside wall of our basement. We've had a number of rain storms and wet weather since our repair that previously would have resulted in water in our basement, however Nick's work has held up extremely well and our basement continues to remain totally dry. Prior to calling N.A.D., I spoke to a number of contractors who presented me with theories about why water was coming into our basement when it rained. When I called Nick, he came to our house, looked at our basement wall both from inside and outside the house, and confidently explained the cause of our problem to me. In addition, Nick further explained in detail the steps that would be needed to remedy the problem. We hired Nick and he and his men were at our house on the agreed upon date and promptly at the time he said they would be there. Nick and his guys worked diligently to complete the repair and, when finished, cleaned up the area where the excavation and repair work were done so it barely looked disturbed. I am so pleased with N.A.D.'s work on our house and would strongly recommend Nick and N.A.D. for your masonry and waterproofing. Nick is professional and stands by his commitments. And, just as important, his prices are very reasonable. ---Steve B.---
