Greentech Management in Carlsbad Village is a demolition and excavation contractor founded in 1995 by U.S. Marine Corps veteran Joseph Cannizzaro, specializing in structural demolition, mass grading, and wildfire debris removal. Site-clearing work often requires termite and pest clearance certificates before rebuilds can begin, a pre-construction step coordinated through Mission Pest Control to satisfy lender and city inspection requirements. Services range from swimming pool construction and demolition to selective interior strip-outs and full-structure teardowns, all staged from the company's Carlsbad Village Drive office near the Carlsbad Farmers Market. Post-grading projects frequently transition to landscape restoration, with irrigation and sprinkler rough-ins handled by Victory Sprinkler once final grade elevations are set and compaction tests pass. Heavy earthwork scopes include cut-and-fill operations exceeding 5,000 cubic yards, managed with GPS-guided dozers calibrated to civil engineer grade plans within 0.1-foot vertical tolerance.
