You can’t fix what you don’t know is there.

A whole-home electrical assessment gives you a clearer picture of how your system is performing, from circuit loads and grounding to outlets, connections, and signs of wear that may need attention.

It’s especially useful if you’re buying, selling, renovating, dealing with an insurance request, or simply want to know your home is safe and up to current standards.

If the fix starts with “I saw a video once,” put the screwdriver down.

A tripped breaker, flickering light, dead outlet, or strange electrical smell can look like a quick DIY job. The trouble is, the real cause is often hidden behind the panel or wiring.

That’s what a service call is for. We troubleshoot the problem, explain what’s happening in plain language, and fix what actually needs fixing — safely and to code.

Your home may be ready for today. Is your wiring?

Older electrical systems were never built for the way we use power now. If you’re dealing with flickering lights, frequent breaker trips, warm outlets, or planning a renovation, a whole-home rewire may be worth looking into.

A proper rewire brings your electrical system up to current safety standards and gives your home the capacity to handle modern appliances, HVAC equipment, EV chargers, and everyday demand with more confidence.

Reliable power starts with testing.

You may not see what happens inside commercial electrical equipment, but your team depends on it every day. Professional testing helps confirm that fuses, connections, and electrical loads are operating safely while identifying concerns before they lead to downtime or costly damage.

Your electrical panel should never be a guessing game. It helps protect the people, equipment, and daily routines that rely on your power.

Looks fine… until it overheats.

A tangle of wires may seem like nothing more than a messy installation, but loose connections, damaged insulation, overloaded circuits, and unapproved work can create serious safety risks.

With decades of experience in older and modern electrical systems, we know what to look for, what needs attention, and how to explain the safest next step without adding unnecessary work.

Reliable power starts with a careful check.

Commercial electrical systems carry significant responsibility. A detailed inspection helps identify loose connections, worn components, heat damage, and other concerns before they affect your people, equipment, or daily operations.

With decades of hands-on experience, we take the time to check each part properly and explain what your system needs in clear, practical terms.

When the power goes out, the right call brings peace of mind back.

A fallen tree damaged the service mast and left this Toronto home without power. Within 24 hours, the damaged connection was repaired to proper ESA standards, allowing Toronto Hydro to safely reconnect the service.

For the homeowner, that meant more than getting the lights back on. It meant responsive communication, professional work, fair treatment, and knowing the repair was done properly.

Storm damage rarely gives you time to prepare. Visit https://langstaffandsloan.com/ so you already know what to do when the unexpected happens.

Ever wonder if you’re paying the right amount?

Electrical bills are easier to trust when the numbers are clear. Proper metering and sub-metering help show how much energy a unit, tenant, or section of a building actually uses.

Old wiring needs experienced eyes.
