Konstantine is simply THE BEST! Honest, straightforward, transparent, professional, extremely knowledgeable, accommodating, flexible, patient, dependable and a good human being with high integrity. I interviewed 5 General Contractors and Konstantine by far stood out for all the reasons I just mentioned. Most importantly, HE CARES!

Having an old building that always needs upkeep is a bit of a struggle. I've had people in the past "fix" things as I go but I wasn't always happy with the end result long term. I was able to talk to Kosta and he took the time to listen to my past experiences and concerns that I was looking to address. After that initial phone call, I left feeling better about who I would want to move forward with. A short period of time later he gave me a thorough plan for what was needed to tackle my project and what to expect as we go along. It's funny to say but communication is very important when it comes to your home. Being shown why certain options / ways of doing things are better than others and why you should use specific materials of higher quality left me feeling at ease. I felt like the end result is what we had went over with him in the previous conversations and I now have something that I don't have to worry about again. I want to say that I've also learned my lesson about sometimes looking for the lowest quote or quickest / shortest way out. Do it once and do it right with this crew!

The amount of experience that Ionian Builders delivers is prestige. I wanted something, and they recommended something else, and it turned out to be better than what I had in mind. So I absolutely recommended them. Highly professional. Very knowledgeable.
