Everyday Office Building Wiring Issues We Take Care Of

Tenants and property managers call us about the same handful of issues during a fit-out. Here is what shows up most in our project consultations.

🔌

Existing Infrastructure Does Not Match Tenant Needs

Landlord-provided electrical infrastructure rarely matches what a specific tenant actually needs on day one. We plan circuit load, outlet placement, and lighting around how the space will genuinely be used.

❓

Unsure Whether Existing Wiring Can Be Reused

Facility managers often cannot tell whether a second-generation space has reusable infrastructure or needs a full rewire. We evaluate existing panels and conduit honestly before recommending a scope.

📈

No Growth Capacity Built Into the Design

Offices that feel adequately powered on day one often become overloaded as teams grow and technology needs increase. We calculate total load with a genuine growth buffer built in from the start.

🤝

Electrical Plan Not Coordinated With Other Trades

Poor coordination between electrical work and framing, HVAC, and other trades causes delays and rework. We coordinate directly with general contractors and other trades to keep a fit-out on schedule.

🚨

Emergency Lighting or Exit Signage Missing

Commercial spaces without adequate emergency lighting and illuminated exit signs commonly fail final inspection. We build these life-safety requirements into the original design rather than retrofitting them later.

📄

Unclear Who Pays for Electrical Work

Ambiguity between landlord-funded infrastructure and tenant-funded circuits causes budget disputes mid-project. We help clarify this split in writing before construction begins.

⚠️

Occupying Space Without Proper Sign-Off

Moving into a fit-out before final electrical inspection can void a lease, insurance coverage, and the occupancy permit. We manage inspection scheduling so occupancy never happens before proper sign-off.

💸

Change Orders From Late Electrician Involvement

Bringing an electrician in after layout decisions are made leads to costly changes once walls are already closed. We get involved from the design phase to avoid this entirely.

📋

No Written Scope Before Construction Begins

Vague verbal estimates lead to disputes over what a project does and does not cover. We provide a written scope of work before any construction starts.

Customer Reviews

Read Before You Book

Office Manager Rachel S.

Kept our build-out on schedule

Markham Electrical Services got involved during the design phase instead of after our layout was already set, which our general contractor said saved us real time. Everything passed inspection on the first attempt.

Practice Manager David L.

Reused our existing infrastructure honestly

We assumed we needed a full rewire but Markham Electrical Services assessed our second-generation space and found most of the existing panel and conduit was reusable. Saved us a meaningful amount on the total project.

Tenant Representative Julie M.

Great work, permit timeline took longer than hoped

The actual electrical work went smoothly but our municipality's permit approval took longer than the estimate. The team kept us updated throughout the wait and explained the delay clearly.

Business Owner Sam K.

Growth buffer already paying off

They recommended extra circuit capacity when we set up our office and we have already added two more workstations without any issue. Glad we listened instead of trying to save money upfront.

Angela P.

Clarified our landlord allowance split clearly

We had no idea what our landlord was actually responsible for funding until Markham Electrical Services walked us through it. Got everything in writing before construction started, which avoided a dispute later.

Facilities Coordinator Marcus T.

Handled coordination with our other trades well

Our general contractor said Markham Electrical Services was the easiest trade to coordinate with on the entire project. Communicated proactively and never became the bottleneck holding up other work.

How It Works

Priced Before It Starts, Tested Before We Go

Book a Time

You get a real arrival window rather than a whole day, and a call if anything moves. Emergency work is dispatched rather than scheduled.

Assessment and Quote

The written figure includes permit and inspection, and the exclusions are set out as clearly as the inclusions, which is where most disputes start.

Installation

Work to the agreed scope with nothing added quietly. If something unforeseen appears, you decide what happens next, not us.

Verified

Tested under genuine load before the panel closes, then certified. Our labour carries two years, the equipment its manufacturer warranty.

New Loads, Old Services

A Full Panel Blocks Everything You Add Next

Tandem breakers filling a board mean the service is already at its limit. The replacement allows for what is planned as well as what is present.

Is There Room in the Panel?

A board full of tandem breakers is already at its limit. Knowing that first saves buying equipment you cannot run.
