Backyard renovation projects that pair pool resurfacing with new hardscape and planting often run concurrently with the concrete, paver, and irrigation work provided by Ultra Landscaping on Lakeshore Drive near Lindo Lake County Park. The company also operates under the Gemstone Pools brand, offering proprietary pebble-surface blends alongside standard plaster, quartz-aggregate, and glass-bead finishes for residential and commercial shells. Structural remodels that add Baja shelves, raised-wall water features, or expanded spa sections require engineered shotcrete and rebar layouts, a scope the crew coordinates with general contractors such as A.M. Ortega Construction, Inc. on Channel Road. Equipment-pad overhauls include variable-speed pump upgrades, cartridge-filter conversions, and automation-system installs using Pentair IntelliCenter or Jandy AquaLink RS platforms.
