What Our Clients Are Saying?
We have served over 200 clients who have sourced the right manufacturer through us and got desired solutions
Alex is the most professional contractor that I’ve ever worked with. He showed up on time, explained everything clearly, and did the most in depth exploration of our basement flooding issue that any other contractor did. It was clear that both he and one of his staff members (also a very nice person and very helpful) were looking to learn as much as possible about the issue in order to provide the best strategy to fix the problem. Our building took a very long time deciding what to do and Alex was patient, responsive, and very easy to work with. I couldn’t recommend working with Alex and his team enough. They are my first choice for any job that my building has to do.
Ben KAlex and his team did an outstanding job replacing my roof and waterproofing the exterior of my home. Rubel and Abdoul, the Project Managers, were professional and efficient, ensuring everything was completed to the highest standard. The new roof looks amazing, and I’m confident my home is well-protected. Highly recommend Alex and his crew!
RedI needed major roof repairs or a new roof and Alex Gregg inspected my roof and gave me the option. I decided to get a new roof especially considering the extended warranty of a few decades. He did a phenomenal job, his people that worked on the roof were very good and very respectful, they did a great job quickly. They cleaned up everything when the job was finished. By the way the price that I paid was also decent. What else would you want? Absolutely recommended!
Alex LodicoOur basement was getting flooded every time it rained. They did a great job waterproofing it, and gave us a 5 year warranty. They also redid our roof, fixed the water damage from the roof leak and fixed our backyard wall. Everything looks beautiful. We are very happy with the work.
