Mainland Services
Mechanical Contractor
Full-scope DWV, water supply, and fixture installation for wood-frame and concrete new construction.
Mainland Services delivers complete plumbing systems for new residential and commercial construction — from complex multi-unit high-rises to wood-frame apartment buildings and commercial tenant improvements.
Our team of Red Seal certified journeymen handles every phase of the plumbing scope: underground rough-in, above-ground DWV systems, domestic cold and hot water distribution, mechanical room tie-ins, and final fixture installation.
We work seamlessly with engineers, general contractors, and building authorities to ensure every system is code-compliant, properly documented, and built for decades of reliable service.
We review mechanical drawings with engineers and the GC to coordinate scope, conflicts, and scheduling.
Trenching, underground DWV, slab sleeves, and water service connections completed before pour.
Above-slab DWV, water piping, and mechanical room rough-in installed floor by floor.
All systems pressure tested and documented before insulation and drywall.
Final fixtures, valves, and trim installed after finishing trades complete.
City inspections passed, as-built drawings provided, systems commissioned.
The earlier you bring us into your project, the better the outcome — from design-assist coordination and prefab planning to full Design-Build delivery. Mainland handles the mechanical scope so your schedule and budget stay intact.
