"Carl and his team were EXCELLENT to work with! Very consultative, did wonderful work, and were very reasonably priced. I have a stone facade house that's over 100 years old and required repointing. Carl was extremely knowledgeable on historic restoration techniques and the specialized materials work like this requires. His crew was efficient and treated my home like their own, cleaning up each day, minding the landscaping, and doing high quality work. I have recommended them to several people and would not hesitate to use them again. See pics for before and after of one of my columns."

"I needed a leaky patio door replaced and this company did an excellent job. Not only did they install and properly flash the door and replace some damaged siding; they also noticed that a nearby exterior electrical outlet was damaged and improperly grounded and fixed that, too. They checked in with me regularly during the work and cleaned up after themselves when it was done. They also literally went the extra mile: when their local suppliers didn't have the siding needed, they drove to Delaware to get it. This is the second job I've hired them to do; if there's a third, I'll have them on speed dial."

"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."

"Excellent. Quick response and they came out the next morning. Always recommend Harvey's."
