Expert Contractors with Years of Experience

Black Sapphire Contracting LLC has been under the operation of ,myself, President Liam Mahoney, for two years. I make sure it is vital that every estimate is thoroughly prepared to ensure that the highest quality of work and most accurate quote is presented. I understand how important it is that a client trusts their contractor- at Black Sapphire Contracting it is at the center of our establishment that we can offer this to the highest level for all our clients. From growing up surrounded by the industry, I have learned from a young age the crucial elements needed to be the best performing company for customers. My many years of experience in the field of construction means I ensure that any employee wearing the Black Sapphire brand is held to the utmost criteria of quality and service. Our company operates using our three pillars of trust, quality and integrity to ensure that all services offered to our clients are performed to the highest of standards- by achieving high-end results with your best interests at heart. My second company which is under my ownership and operational expertise, Green Giant, INC has been established since 2005. A horticultural company whose clientele is largely property managers and commercial companies. When Black Sapphire Contracting was established we decided to start off and conquer the field of pavement asset management. As president, I recognized the generally low quality of work from many of my competitors in this field and knew that we could give a long-lasting service at a better price and remove the stigma of asphalt contractors. As we grew we began attending to all aspects of building and construction but I believe our name pays great homage to where we started out and the core of our company. I believe while asphalt sealant is drying it has a beautiful sapphire-like look, before it cures and finishes.

 I not only speak for the company , but also myself, when saying that we really look forward to hearing from you and hope you choose Black Sapphire Contracting for your future needs. By working with us we assure to limit the risk of litigation liability for your business and perform our services to the highest level of quality to guarantee your business will be presented in the most professional and aesthetically pleasing way.
