They did a complete gut renovation on my NYC condo. It turned out amazing. They completely understood my budget. They stayed on the job until it was completed. They the left the job site clean and tidy at the of the day. The quality of work was excellent.
I would hire them again tomorrow if I had a project to do.

We hired Alex and his project manager Bob to help us install a washer/dryer in our pre-war Irving Place building. While it sounds like a simple task, the job actually entailed rewiring the entirety of our three-unit apartment (given building-wide electrical limitations) as well as redirecting a significant amount of plumbing work. Alex and Bob went above and beyond! Not only did they finish the task early (by over a week), but they uncovered a number of preexisting issues and fixed them along the way, without adding to/amending the contract or price. They were also exceptional communicators and kept us abreast of progress on a daily basis via photos and status texts.
Given that we have a newborn son, we were really concerned about displacement and cleanliness and our apartment looked like they had just hired a team of professional cleaners when they finished the task.
We have historically had very mixed (ie negative) experiences with contractors and would say that Alex and Bob have restored much of our faith and trust, and we could not recommend them more highly. They were world-class in integrity, communication, professionalism, and quality of work, and will be our first and only call for all renovations/contracting moving forward.

GCI renovated our 2 bedroom/2 bathroom E. Village apt during the middle of the pandemic, from August 2020 to May 2021. From start to finish, Alex, Carlos and their team, as well as their vendors did an excellent job and were a pleasure to work with. Alex and Carlos have a deep understanding and appreciation for every detail, with great judgement, experience and professionalism. The final result has exceeded our expectations, and we will be able to enjoy our new space x decades to come. I rec'd them highly without hesitation.

We purchased a 2 bed, 2 bath apartment that required a full gut renovation. Everything had to be torn up, down and apart so we can remake our future home. The mistake on our part was underestimating what it would take for our first renovation project. There was so much to do and so much we didn't know. We are so thankful that Green Conversions took our project. They were highly recommended from an architect friend who had also trusted Alex for his home renovation.
Green Conversions is professional from the very start - open and transparent about costs, work effort and estimated timing. Not once did we feel anything was unreasonable or questionable; they always shared ideas and options but left the decision with you. They are incredibly thoughtful in their approach, working with you as a partner rather than just a client. You can tell they care about your space and take pride in their work.
Without their guidance and patience, this project would have run over much longer than either parties would have wanted. They helped us prioritize design research and detailed decisions; they leveraged their contacts to help us get quality, beautiful millwork to cover our PTAC units; and when we purchased the wrong shelving for our kitchen, their team magically resolved the issue but custom building a platform that looked completely integrated. This was an enormous project. If we were to renovate again, Green Conversions would be the first contractor we would call.

I would strongly recommend Green Conversions for renovation projects in NYC. When we undertook our renovation, we were weary of picking the wrong contractor, as we had heard many horror stories. Ultimately, after speaking with several references, my wife and I decided to use Alex for our renovation. We are very happy with the finished product and Alex and his team were great all along the way. Alex was intimately involved throughout our project. He and his team were always very respectful and earned high marks from our building manager. In addition, Alex was extremely detail oriented and transparent when it came to change orders. He always had good ideas regarding changes that made a big difference in terms of the final look of our apartment. Furthermore, following the end of the project, there were several areas where we wanted to make some tweaks and Alex remained his normal responsive self and was extremely helpful in remediating those issues. In short, two thumbs up.

As a first time home owner, I truly feel like I found a unicorn in Alex and the team of Green Conversions Inc., who far exceeded our every expectation. We originally hired a contractor used by a family member, but quickly became one of those NYC horror stories after the contractor stopped returning our phone calls and left us completely stranded. After asking many friends for recommendations, we decided to go with Green Conversions Inc., a recommendation from a friend who is an architect working in the business. Our only regret is not having gone with Green Conversion in the first place. We were on a time constraint and Alex was beyond professional- he completed our kitchen renovation before the expected time frame, came on budget with no hidden/extra costs, met with us every week, promptly answered calls, and was extremely diligent in meeting all co-op and DoB requirements. Most importantly Green Conversion’s craftmanship is unparalleled and the entire team a pleasure to work with. We always felt like we were in good hands and never doubted Alex’s level of dedication or honesty. Even weeks after the renovation was completed, our project manager still made himself readily available to answer any questions that arose. We can’t say enough good things about Green Conversions, nor thank them enough for making our vision into a reality and transforming our first apartment into our dream home!

We would hire Green Conversions Inc over and over again! They committed to an enormous project and not only finished on time, but made up for days that could have easily been lost when we made changes and when unforeseen field site issues arose . More importantly, every member on the team was professional, took personal ownership of their work, and was a pleasure to work with. We absolutely love our new home! Thank you, Green!

I will preface my review by saying that I've had experience renovating--my homes and those of others--in different countries but never in NYC. Well-meaning friends and family warned me that it was bound to be painful, over-budget, delayed and frustrating no matter what. I am happy to report that none of this is true when it comes to Green Conversions Inc. From the get-go, from our very first conversation, this contractor proved exceptionally professional, thorough, attentive, proactive and reliable. Every piece of the work (regardless of his sub-contractors) was masterfully coordinated and completed on time, impeccably, and on budget. Whenever budget was exceeded it was entirely due to my own wish to add something I had not foreseen in the initial scope of work. In a very impressive and reassuring way, this contractor anticipated and flagged all decision points, choices I would have to make, things I ought to reflect on, and managed my time and expectations and budget accordingly. He also introduced me to an excellent architect and shepherded me through the complexe obtention of permits and all the tedious paperwork I wasn't familiar with. Having my contractor's support throughout this administrative process was at once reassuring and confidence-inspiring. His excellent teams were, from start to finish, on-time, tidy, considerate, professional and pleasant. They worked very hard through some very hot summer months in the city and the project was delivered on time, in the most serene conditions. The contractor himself was a joy to work with: always making me feel heard, understood and seen. always patient and on-the-ball and exceptionally responsive on email, phone and text 7 days a week. It was a pleasure to collaborate with someone so tuned-in to his client and her worries, and so willing to go the extra mile whenever technical challenges popped up on site. Green Conversions Inc became the envy of all my friends who'd experienced renovations and were just stunned when I described how smooth our project was. Many people I know end up firing or suing their contractor and I couldn't believe how energizing and fun it was to work with a contractor. Even my building's Superintend and neighbors loved him. I trust and recommend this contractor wholeheartedly. In case you thought renovation projects can never be completed on time, on-budget and without frustration and anger, think again.

I highly recommend Alex Trivizas and Green Conversions as a general contractor. Alex is very easy to work with ; he's friendly and smart and really listens to your ideas and concerns. He and his crew are real pros - competent, on time, clear budgeting, etc. I had several change orders which were all reasonably priced out. The work in my apartment was extensive from a new kitchen and bath (Alex has a wonderful cabinet maker and tiler) to a closet conversion, plastering, and painting (all extremely neat - really flawless).

Alex and his team did a fantastic job renovating my studio apartment. It was a gut renovation and it all turned out perfect! Alex also was great to stay in touch with me and answer all my questions. Lastly, he followed up on anything I asked him to do once the job was complete. I highly recommend Green Conversions!
