Residential decorating is unregulated. Confirm registration if it matters, and rely on a written scope and markup disclosure.

Frequently asked questions

How much does an interior designer cost?

Designers charge four ways: an hourly rate, a flat per-room or per-project fee, a percentage of the total project cost, or a markup/commission on furnishings they procure. The biggest cost driver is scope — a single-room refresh versus a whole-home renovation. Agree the pricing model in writing before any work, because they produce very different bills.

How do I find a good interior designer in Sarnia?

Look for a Sarnia designer whose portfolio matches your taste (their style is hard to override), and ask to speak to a recent client about budget discipline and communication. Local designers know local trades, showrooms and lead times. Agree the pricing model and a realistic furnishings budget before committing.

What should an interior-design proposal include?

A clear scope: the rooms covered, deliverables (concept, mood boards, floor plans, spec/shopping list, elevations), number of revisions, the pricing model and whether product markup applies, the furnishings budget assumption, and project-management scope if they'll manage trades. Vague 'design services' with one number hides scope disputes.

Is the furniture and materials cost included in the fee?

Usually not — the design fee buys the designer's time and expertise; furniture, materials and trades are separate and typically the bulk of the spend. Clarify whether the designer marks up procured items or passes trade discounts to you, and whether their fee is on top of or inside the furnishings budget.

What's the difference between an interior designer and a decorator?

A decorator focuses on surfaces and furnishings — colour, fabrics, furniture, styling. An interior designer can also work on space planning, layout and construction details, often coordinating with builders and architects. For a cosmetic refresh a decorator suffices; for reconfiguring space or a renovation you need a designer.

How much does an interior designer cost in Canada?

Hourly rates commonly run CAD 100-200, with per-room flat fees CAD 2,000-6,000 and whole-home design CAD 10,000-40,000+ (fee only). Rates track close to US levels in major cities.
