Cocell Contracting finishes basements into livable, code-compliant space — suites, theaters, offices, and baths — with in-house framing, HVAC, plumbing, gas, and electrical under one accountable plan.
Finishing a basement means framing, insulation, egress, moisture control, and often adding a bathroom or wet bar — each of which touches a different trade. Below-grade work has its own code requirements for egress windows, ceiling height, and ventilation. Because every trade is in-house, we handle the framing, mechanical rough-ins, and finishes as one coordinated project rather than a string of subcontractors.

We start with an on-site consultation, then develop a design and a detailed, line-item scope so you know exactly what is included. Once approved, our own crews handle the work through final inspection, with written change orders before any added work and weekly progress updates with photos.
