Real reviews from families we've helped across the GTA.
"We had Kolji Bros upgrade our old 100A panel to 200A and install an EV charger. The work was incredibly clean and they explained everything. Highly recommend for any home electrical work!"
"They installed 8 pot lights in our basement renovation. The spacing was perfect and they walked us through all the dimmer options. Very professional and tidy—no mess left behind."
"Our 1960s home had aluminum wiring that was a fire concern. Kolji Bros installed AlumiConn connectors throughout—much more affordable than full rewiring and now we have peace of mind."
Residential Electrical FAQ
Common questions from Waterdown homeowners.
In Ontario, most electrical work beyond simple fixture replacements requires an ESA permit. This includes panel upgrades, new circuits, rewiring, and outlet additions. We handle all permit applications and arrange ESA inspections as part of our service—you don't have to worry about the paperwork.
Panel upgrades vary based on your home's specific needs. A 100A to 200A upgrade typically ranges from $2,500-$4,500 depending on factors like panel location, meter base replacement needs, and whether Waterdown Hydro coordination is required. We provide detailed quotes after assessing your home.
Aluminum wiring itself isn't inherently dangerous, but the connections can loosen over time and create fire hazards due to oxidation and different expansion rates than copper. We can install approved AlumiConn connectors at all connection points—a cost-effective solution that eliminates the risk without full rewiring.
A general guideline is one 4" pot light per 4-6 square feet, or one 6" pot light per 6-9 square feet. For a typical 12x14 ft room, you'd want 4-6 lights. We'll assess your specific space, ceiling height, and lighting goals to recommend the optimal layout and quantity.
Yes, we can add outlets to older homes including those with plaster walls, knob-and-tube wiring, or limited panel capacity. Depending on your existing electrical system, we may recommend running new circuits or upgrading your panel first to safely support additional outlets.
Yes, we're experienced with knob-and-tube wiring found in many Waterdown homes built before the 1950s. Options include partial replacement (just the problem areas), full rewiring, or working around existing K&T for additions. We'll assess your situation and recommend the best approach for your home and budget.
For a typical room with 4-6 pot lights and existing attic access, installation takes about half a day. More complex installations—like finished basements or multi-room projects—may take a full day or more. We'll give you a time estimate with your quote.
Yes, we provide free estimates for most residential projects. For complex work requiring detailed assessment (like full home rewiring), we may charge a nominal fee that's credited toward your project if you proceed with us.
