“Once construction began, the project was executed with impressive coordination across all phases: Demolition was handled quickly and cleanly. The team was respectful of our property and made sure to minimize disruption throughout the process. The masonry crew did exceptional work. Every stone was set with precision, and the finished patio, poolside, fireplace, and stonework blend seamlessly into the landscaping making the whole yard an extension of the work. The carpentry team brought a level of craftsmanship that truly elevated the space. From custom wood accents and trim work, their attention to every detail and quality of build were outstanding. The pool renovation also exceeded our expectations. The waterline tile and PebbleTec finish are flawless, and the integration of the pool into the new patio layout is seamless.”
