King County · Electrical Contractor
Seattle commercial & industrial electrical
Seattle is where much of our most demanding work lives — surgical suites and cardiac labs in occupied hospitals, radiation-oncology vaults, and landmark new construction.
Our Seattle portfolio runs from operating rooms and electrophysiology labs to a shielded linear-accelerator vault and the feature lighting behind a landmark glass gallery — work that demands isolated power, essential electrical systems, and careful phasing inside busy facilities.
For Seattle general contractors and healthcare facilities, H&M brings a rare combination: two-plus decades of critical-environment experience, IBEW-qualified crews, and single-source design-build capability.
Selected Seattle projects
Healthcare & Critical EnvironmentsSurgery center — operating rooms, PACU & sterile core
Fully equipped operating rooms with surgical booms and integrated power, plus post-anesthesia recovery (PACU) and a sterile processing core — the essential electrical systems a surgical suite depends on.
Healthcare & Critical EnvironmentsHeart & vascular center — EP and cath labs
Electrophysiology and cardiac catheterization labs with ceiling-mounted imaging systems, isolated power, and the equipotential grounding these interventional-cardiology spaces require.
Healthcare & Critical EnvironmentsRadiation oncology — linear accelerator (LINAC) vault
Underground conduit rough-in and power distribution for a shielded linear-accelerator vault — high-stakes coordination beneath the concrete radiation shielding of an oncology suite.
New Construction & Design-BuildLandmark gallery — new construction & feature lighting
New-construction electrical for a landmark Seattle Center gallery, including the specialized feature lighting behind large-scale glass installations, indoors and out.
Foundation headquarters — tenant improvement
