"Perfectly. Carl met with me for a challenging problem/project I had previously hired (years ago) another contractor to solve/install. It involved installing a natural stone “stairway,“ with landings, on two small hills. The previous contractor did not succeed. Carl assessed and knew instantly what needed to be done, gave me a reasonable price, communicated effectively, always showed up on time with his crew and, at the risk of sounding hyperbolic, did a perfect job. Every member of his crew was customer and project focused. I already plan to welcome them back for another project elsewhere on my property."

"Mike has done so projects for us! We call him for pretty much everything in our house. He installed lights, ceiling fans, range hood, even hung pictures on masonry walls! He's the definition of a handyman - the best!"

"Brad and his team were amazing. From initial communication to finished product, it was simple and seamless. We now have a very professional basketball hoop at our home, that will provide years of pleasure for my son and I. Can’t recommend Tri State Assembly enough."

"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."
