Give each contractor the same brief

Describe your present concern, planned equipment and available reports consistently. Mark observations as homeowner-reported and attach any professional assessment with its author and date. Ask each business to explain what further site review is needed. If one proposal assumes a same-capacity replacement and another includes a service upgrade, their totals do not describe the same purchase. Resolve that difference before deciding which scope meets the goal.

Ask what is included

Request the proposed equipment identifiers, circuit work, service changes, assessment, permits, utility coordination and finish restoration in writing. Ask which existing equipment remains and whether any proposed items are allowances awaiting confirmation. Keep exclusions beside the inclusions. “New electrical panel” is too broad to tell you whether the price covers the work you expect, and a web price range cannot account for unresolved site conditions.

Identify who carries each dependency

Ask who contacts the utility, books the outage, arranges inspections and responds if an inspection identifies additional work. Clarify how any outside charges enter the proposal. What conditions could change the start date, outage or scope? A written dependency does not remove uncertainty, but it gives you a way to compare the proposals honestly. Avoid treating an unconfirmed booking as a guaranteed schedule.

Use a written agreement and change process

Alberta's contractor guidance recommends written estimates from more than one business and a written contract describing work, materials and timing. It also recommends written approval and a signed contractor statement for price changes. Ask how your agreement handles discoveries, substitutions, payment stages and cancellation conditions before signing. For advice about the legal meaning of your specific contract, use an appropriate adviser rather than a website checklist.

Define the finish line

Ask what handover includes: completed scope, equipment information, circuit documentation, relevant permit and inspection records, and any outstanding actions. Keep a future-load assessment separate from statements about insurer acceptance or resale value. A contractor invoice is useful evidence of the billed work but is not every approval the project may need. Compare the final proposals on a shared scope, documented assumptions and accountable follow-through, then keep the accepted version.

Questions when reviewing the proposals

  • Are these quotes solving the same documented problem and future-load brief?
  • Which allowances or exclusions could change the accepted scope?
  • Who obtains outstanding evidence, approves changes and supplies the completion records that define the finish line for this particular project?
