Choosing the right contractor is the single most important decision in any renovation. Start by confirming the company is properly licensed and insured, and ask to see completed projects in communities like yours.
Insist on a fixed-scope quotation, clear stage payments and a named, English-speaking project manager. Ask how they handle community NOCs and approvals, what warranty they provide, and how they protect your home and neighbours during the works. The answers tell you everything about how the project will run.
