Choose an interior renovation contractor by checking how they will handle your specific rooms, not just how their finished photographs look. The strongest comparison covers the written scope, protection of the rest of the house, coordination between trades, decision-making and handover.
A kitchen, bathroom or multi-room interior project brings work close to everyday living. Small gaps in planning can affect access, privacy and the rooms you intend to keep. Use the interview to find out who is responsible for those details before choosing on price.
Start with a project brief every contractor can use
Give each candidate the same information: property location, rooms involved, approximate dimensions, existing-condition photographs and a list of what stays. Include known concerns such as uneven floors or previous water damage without trying to diagnose them yourself.
Separate definite requirements from ideas. “Replace the damaged floor” is different from “price an option to continue the same flooring into the hall.” Ask for options to be identified rather than mixed into a total that cannot be compared.
Ask for relevant evidence, not just a portfolio
Look for work with similar constraints: renovating an occupied home, matching existing trim, integrating new cabinets or working in a compact bathroom. A photograph of a large new-build kitchen does not answer how a team manages a tight renovation around retained finishes.
With permission, speak to a past client about process. Ask what changed after work began, how decisions were recorded and whether the finished work was explained at handover. Avoid asking only whether they liked the result; the most useful answers describe what actually happened.
For finish quality, request closer views of transitions, corners, cabinet alignments and the junction between old and new work. Then ask what tolerances or finish expectations will be agreed for your project rather than treating a photograph as a specification.
Discuss protection and access in concrete terms
Ask the contractor to walk through a typical workday. Where will materials arrive? Which entrance will trades use? Where will debris go? Which parts of the home must remain accessible?
- Identify the rooms and floors to be protected, including delivery routes.
- Agree on separation between occupied areas and the work zone.
- Discuss dust control and cleaning without expecting a dust-free renovation.
- Plan advance notice for water, electrical or room-access interruptions.
- Keep children and pets out of construction areas.
- Record working hours, parking arrangements and site security responsibilities.
If continued occupancy depends on keeping a kitchen, bathroom or safe access route usable, put that requirement in the brief. Do not assume it will be possible simply because work is indoors.
Identify who does and coordinates each part
Find out who manages the site, who answers your questions and whether those roles change during construction. Ask which work is subcontracted and who is responsible for scheduling it.
For electrical work, verify the business that will perform it. Ontario’s Electrical Safety Authority explains that general contractors need an electrical contractor’s licence to perform residential electrical work themselves; otherwise an appropriately licensed subcontractor is needed, subject to the stated exemptions. A general claim of being “licensed” does not answer this question.
Request current insurance information and ask how relevant coverage will be verified. The objective is to establish the actual arrangements for your project, not collect reassuring labels.
Compare the scope before comparing totals
Read proposals side by side. Check demolition, disposal, surface preparation, backing, waterproofing where relevant, installation, finishing, protection and clean-up. Ask whether fixtures and finishes are specified products or allowances.
A cheaper proposal may genuinely be more efficient or may omit work you expected. A higher price is not proof of quality either. Ask each contractor to clarify the same missing items so you can make a fair decision.
Ontario’s renovation guidance recommends written estimates and a detailed contract. Use the contract to settle responsibility for permits, payments, scope and changes; get professional advice if a substantial agreement contains terms you do not understand.
Use one scenario to test communication
Hypothetical interview question: “You uncover a damaged area behind the old shower. What happens before extra work proceeds?” A useful answer explains how the area is made safe, what evidence you receive, how options are assessed and how cost and schedule changes are approved.
Also ask what happens if a selected product is unavailable. Substitutions should be discussed for appearance, compatibility, price and timing, not quietly made on site.
Agree on what completion means
Ask about the final inspection of the work, applicable authority sign-offs, a written deficiency list, product instructions and the contact for later concerns. Clarify which warranties apply and who provides each one.
