“William Honor did 4 large jobs for me. The best part about BluStar is they are 100% honest and do not play games with either your money or your time. That means a quality job without over-runs, and all expectations were met or excided. Billy did 2 bathrooms, a kitchen and a large extension. Oh, and a deck. I know that sounds like a lot and it was, but I never had to sweat the details.”
Development Design Services
Civil Engineers & General Contractors in Mount Sinai.
“We are currently working with DDS on a significant exterior project that includes; roof, siding, masonry, and landscape design and we could not be happier with the services that are being provided! The attention to detail and professionalism is unparalleled. We have had several contractors provide us estimates and simply hand us a catalog to select materials with no guidance whatsoever. Edwin approached the project from an artistic point of view and was able to provide us with an image of what the house would look like upon completion which literally took all of the guess work out of the equation. Their team of contractors are very mild mannered and approachable and take the extra time each day to clean up and leave the work area spotless. We are beyond thrilled that we chose DDS for this project and look forward to our house being the envy of the block upon completion!”
