"I am absolutely pleased with GJP Developers. From my initial meeting with, Gary, the owner, throughout the entire project experience, there was clear consistent communication. All of my questions were answered. The crew were efficient, timely, respectful and skilled. They built a powder room on my 1st floor. The job was completed earlier than the original plan. I recommend GJP Developers with the highest commendations."

"Mr. Kotarja and his associates efficiently completely my project. When, what I thought was simply an uncomplicated stucco repair and replacement project, Mr. Kotarja showed me in great detail, why and how the foundation of a very old house, needed to be strengthened and reinforced first, with cider blocks and cement before the stucco work could be started. Despite a few days of rainy, non-workable weather, Mr. Kotarja and his associates persistently stayed with the project to its conclusion. All phases of the project were completed to my total satisfaction."
