Services

Electrical, Mechanical & Civil Services, seventeen trades, one partner.

Electrical, low-voltage, civil, and mechanical work done by our own crews, so schedules stay tight and quality stays ours to own.

Our Self-Performed Trades

Every trade on this page is delivered by in-house crews working out of our own fleet. That gives owners and general contractors one accountability chain from preconstruction to closeout: one schedule, one point of contact, and quality that stays ours to own. WIL-Surge Electric holds Wisconsin electrical contractor license #1103087-EC and has served Wisconsin since 1993.

Hydro Excavation

Non-destructive precision digging with pressurized water and vacuum to expose utilities safely. Non-destructive hydro excavation exposes utilities and digs precise trenches without the strike risk of mechanical digging.

Learn about Hydro Excavation

Earthwork / Grading

Site preparation, excavation, and grading that establishes the right foundation. Mass grading, fine grading, and site preparation that set the table for every trade that follows.

Learn about Earthwork / Grading

Concrete

Foundations, transformer pads, and equipment installations that protect your systems. Foundations, flatwork, and site concrete placed by crews who understand the tolerances electrical and mechanical systems demand.

Learn about Concrete

Mechanical Systems

HVAC coordination and mechanical-electrical integration for seamless performance. HVAC and mechanical system installation delivered alongside our electrical scopes, from one accountable mechanical-electrical partner.

Learn about Mechanical Systems

Select Demolition

Safe, controlled demo with coordinated debris removal and recycling to prep your site. Surgical select demolition that clears the way for renovation without disrupting the occupied spaces around it.

Learn about Select Demolition

How the Trades Fit Together on a Commercial Build

Commercial construction runs in a sequence, and the trades on this page follow it. Earthwork, grading, and hydro excavation prepare the site. Underground utilities and concrete put conduit, foundations, and transformer pads in place. Power distribution, high voltage, and mechanical systems go in as the building takes shape, and low voltage, network and data, AV, and lighting finish the work ahead of closeout. Every handoff between those stages is a place where schedules slip when separate subcontractors are waiting on each other.

When one company carries several of those scopes, the handoffs happen inside the same team. Our Design / BIM specialists model the electrical work before crews mobilize, so clashes get caught on screen instead of in the field, and the crew placing a transformer pad already knows what equipment will sit on it.

Scoping Multiple Trades in One Request

Owners and general contractors get the most from a multi-trade partner by sharing the full picture early. Send drawings and specifications for every scope you want priced, note the delivery method, whether hard bid, design-build, or negotiated, and flag phasing requirements such as work in occupied buildings or around an academic calendar. If a project is still taking shape, tell us which trades you expect to need, and our estimating team can help sort out where one scope ends and the next begins.
