How to Select a Contractor: The Ultimate Checklist

Choosing a contractor is one of the most important decisions in a renovation. The right team must understand the scope, coordinate trades, communicate clearly, and document the work—not simply offer an attractive total.

Use this checklist to compare contractors consistently before signing a renovation agreement.

Prepare Before Contacting Contractors

1. Define the project goals

Write a short description of what you want to change and why. Identify the rooms involved, the problems the renovation should solve, and the features that matter most.

Planning Item	What to Record
Scope	Kitchen, bathroom, basement, full home, or commercial space
Priorities	Must-have features and optional upgrades
Existing information	Photos, measurements, drawings, or reports
Timing	Preferred start window and important constraints
Decision-makers	Everyone who must approve scope and selections

Clear goals help contractors prepare comparable proposals and identify questions early.

2. Decide what type of contractor you need

A single-trade repair and a multi-room renovation require different management. A general contractor is most useful when the project includes several trades, inspections, material coordination, or a sequence of dependent tasks.

Build a Qualified Shortlist

3. Look for relevant local experience

Review contractors who work in your area and have completed projects similar to yours. Local experience can help with site access, scheduling, permit coordination, and familiarity with common property types.

4. Review the portfolio carefully

Look beyond overall room photos. Check transitions, tile alignment, cabinetry fit, trim, corners, and other finish details. Ask what part of each project the contractor managed and whether the example reflects a scope similar to yours.

5. Read reviews and contact references

Look for patterns in reviews rather than relying on one comment. Ask references whether communication was consistent, changes were documented, the site was managed responsibly, and the completed work matched the agreed scope.

Verify Business and Project Protections

6. Confirm insurance and WSIB coverage

Ask for current documentation. Clarify which subcontractors will be involved and how their qualifications and coverage are managed.

7. Confirm permits and trade requirements

Ask who determines permit needs, prepares submissions, schedules inspections, and coordinates specialized work. Electrical and plumbing work should be completed by appropriately qualified trades where required. Structural changes may require stamped structural drawings.

Compare Proposals Properly

8. Request a detailed written proposal

Every proposal should make the scope understandable. Review:

• demolition and disposal
• labour and trade work
• materials, fixtures, and allowances
• permit and inspection responsibilities
• exclusions and owner-supplied items
• anticipated schedule
• payment structure; and
• the process for changes or hidden conditions.

When comparing contractor pricing models, use What Is the Hourly Rate for a General Contractor? as background. Then compare the actual scope and assumptions in each proposal rather than choosing by one rate or total alone.

9. Evaluate communication before signing

The estimating stage often shows how the contractor will communicate during construction. Look for clear answers, reasonable response times, written follow-up, and a willingness to identify uncertainties rather than hiding them.

Red flags include:

• pressure to decide immediately
• vague scope descriptions
• reluctance to provide documentation
• unexplained differences between verbal promises and the written proposal; and
• no clear process for changes.

Review the Contract

10. Confirm the essential terms

The contract should identify the parties, property, scope, responsibilities, schedule, payment terms, change-order process, cleanup, and warranty information. Read the full document and make sure important verbal commitments appear in writing.

Do not sign with blank sections or unresolved scope questions. If a term is unclear, ask for an explanation or revision before work begins.
