Five things to confirm with any firm, on this list or not, before you sign. The rules below are Newfoundland and Labrador's and St. John's's.
Ask the firm for a clearance letter from WorkplaceNL, which confirms it is registered for workers' compensation and its account is in good standing. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.
Ask for a certificate of insurance that names the firm and shows commercial general liability coverage in force for the dates of your job, and check that the subcontractors it brings in are covered too.
Building permits for homes in St. John's come from the City of St. John's, and removing walls, moving plumbing and adding circuits usually need one. Agree in writing who applies for the permit and books the inspections.
Get the scope of work, the payment schedule tied to stages of the work, start and finish dates, how changes are agreed and priced, and who handles permits and cleanup, all in one signed contract before any work starts.
A renovation is not a new home, so the new home warranty rules usually do not apply: get the firm's own workmanship warranty in writing, with what it covers and for how long. Renovators in RenoMark, the Canadian Home Builders' Association program, offer a minimum two-year warranty on their work.
The 10 firms on this list fall into 3 groups, read from what each firm's own site says it does and how it is listed on Google.
Renovation companies renovate existing homes, one room at a time or all of it at once.
General contractors run building projects of many kinds and bring in the trades each job needs.
Design-build firms design the project and build it under one contract, so one firm answers for the drawings and the work.
The two overlap. A renovation contractor works on existing homes, while a general contractor may also take on new builds and additions. Many firms do both, so judge them on the projects they show rather than the label.
RenoMark is the renovator program of the Canadian Home Builders' Association. Members agree to a code of conduct that covers written contracts, a warranty on their work and liability insurance.
Ask each firm to price the same written scope, split into labour, materials and allowances for items you have not chosen yet. A low quote often has small allowances that grow once the work starts.
Often, when the work covers one or two rooms. Full-home renovations, work that shuts off water or power for days, and jobs that disturb older materials such as asbestos in plaster or flooring can make it hard to stay. Ask the firm how it will stage the work and keep a kitchen or bathroom usable.
Ask the firm for a clearance letter from WorkplaceNL. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.
Building permits for homes in St. John's come from the City of St. John's. For home renovation, removing walls, moving plumbing and adding circuits usually need one. Many firms apply for the permit as part of the job, so agree who does it before you sign.
How many renovation quotes to get, how to make every contractor price the same job, estimate against quote in each province, and how to read three bids line by line.
What renovating a house costs in Canada in 2026: per-foot bands by scope, totals by house size, prices in Toronto, Vancouver, Calgary, Edmonton and Ottawa, and the tax, permit and contingency lines.
The order of work from scope and permits to the final inspection, who signs off each stage in Ontario, BC and Alberta, how long a full-home job takes, and when to move out.
