Interior design covers a lot more than picking paint colours. In Mississauga's renovation market, designers typically handle space planning, material and finish selection, lighting layout, custom millwork and cabinetry specs, furniture sourcing, and coordination with contractors or trades on site. Some work purely on the creative side and hand off construction drawings to a builder; others operate design-build style, managing the renovation from concept through installation. We've profiled 13 firms in this category, ranging from full-service design-build studios to independent designers who consult on single rooms.
What to look for before you hire
Ask to see a portfolio of completed projects that match your home's style and scope, not just mood boards. Find out whether the fee is a flat rate, hourly, or a percentage of the total project cost, and get that in writing before any purchasing starts. Check how they handle trades: do they have their own crews, or do they bring in outside contractors you'll need to vet separately? A good designer will also give you a realistic budget range early on, rather than letting costs surface only after materials are ordered.
