    Dom did an amazing job fixing a brick wall for us that was badly damaged due to water damage. He was the only contractor that was willing to take on the project as many didn't want to do the work. He was great to communicate with and walked me through his method. I would highly recommend Dom. He also is very clean and tidy which was a bonus.

    We recently hired New Way Interlocking to tackle the landscaping around our new pool, front, sides of house as well as jewel-stone on our front porch. Our property presented quite a challenge due to the complex elevation and grading requirements . From the very beginning, Mike and his entire crews meticulous approach and extensive experience were evident. The team was professional and paid attention to every detail, ensuring that the project not only looked stunning but was also structurally sound. Drainage and erosion control was carefully planned and executed properly which is crucial in a setting like this. The final result is a beautiful, solid, functional outdoor space that blends with the pool area and enhances our property's overall aesthetic. We were impressed with their commitment to quality. They showed up everyday on time when they said they would and worked exceptionally hard throughout the day. Special thanks to Tyler on the team - such a polite, hard working young man. The materials used were top-notch, and their attention to the smallest details, from design to stone placement, was outstanding. Overall, we couldn't be happier with the transformation of our pool area. The challenging grading was expertly managed, resulting in a landscape that is both beautiful and functional with no water pooling in any area. They also warranty and guarantee their work. We highly recommend New Way Interlocking to anyone in need of a skilled, dedicated, and meticulous landscaper. Their work exceeded our expectations, and we are thrilled with the outcome. Several neighbors have been complementing the work and asking for Mikes contact info.

    Build or replace decking-
    We contracted Green Side Up to build a relatively large deck in our backyard. We had an older wooden deck which we wanted to replace with a new composite deck. It was a great pleasure to work with Jay and his crew to do this project. His carpenter (Dennis) did a fantastic job. We were impressed with the frame and the structure. We had a few delays due to the city permit, but at the end we are happy with the work and our new deck. We had two city inspections and both passed right away. Thank you Jay for the work!
