Things to know for your project
Things to know for your project
Conditions, constraints, and on-site decisions that shape the final project cost.
Water damage behind the siding
Trigger: Rotten wall sheathing or framing is discovered behind the vinyl siding when the existing mast is removed.
A general contractor would need to repair the sheathing or framing. This example identifies approximately $450 in possible additional wall repair work.
Inspector-mandated AFCI breakers
Trigger: The inspector requires AFCI (arc-fault circuit interrupter) breakers on existing branch circuits during the panel replacement.
The electrician would install AFCI breakers to bring existing circuits up to current code. This example identifies approximately $1,200 in possible additional work.
Different site conditions or Alectra Utilities requirements
Trigger: A contractor confirms site conditions and Alectra Utilities' specific requirements for the property differ from what was described.
The final cost may shift once a contractor confirms site conditions and Alectra Utilities' specific requirements. This example does not assign a price to that unknown.
The real conversation behind this estimate
The real conversation behind this estimate
This is the how RenoFiz gathered the facts and turned a simple request into a scoped estimate.
Hi there — I'd like a service upgrade. Overhead power lines attach at the corner of my house and drop down in a pipe to the meter base on the front corner, and my panel is inside the garage. So I'll need:
- new lines pulled from Alectra Utilities
- a new overhead connection with a pipe down to a new meter base
- and a new 200 amp panel inside the house
That's a standard 200-amp service upgrade. With Alectra Utilities, there are specific mast-height and meter-base requirements an electrician will need to verify.
A few questions to price it accurately:
Question: What's your postal code (just the first three characters, e.g., L3R)?
Question: Roughly how far is the wire run from the outdoor meter base to the indoor panel?
Question: What's the exterior siding where the new mast and meter will mount?
- Stucco
- Wood Siding
- Vinyl Siding
- Brick/ Stone
- Fiber Cement (Hardie)
Photos that would help If you can, please share:
- The current overhead service mast and where the wires attach.
- The meter base on the exterior.
- The electrical panel in the garage (door open so I can see the breakers).
- The path or wall between the meter and the panel.
What's your postal code (just the first three characters, e.g., L3R)?: L3R
Roughly how far is the wire run from the outdoor meter base to the indoor panel?: 10ft
What's the exterior siding where the new mast and meter will mount?: Vinyl Siding
Thanks — that's everything I need to put together your estimate for the 200-amp service upgrade in Markham.
Photos that would help Before I finalize, a few photos would confirm the exact mounting for your vinyl siding and the garage panel layout:
- The overhead service mast and where the wires attach.
- The meter base on the vinyl siding.
- The electrical panel in the garage (door open).
- The wall area between the meter and the panel.
If you can't grab photos right now, no problem — I'll proceed with what you've given me. Want me to generate the estimate now?
