What a renovation contract should spell out to protect you

Most homeowners sign a renovation contract after a friendly handshake and a WhatsApp quote, then discover halfway through that the contractor's definition of "complete" and theirs are fundamentally different. A proper contract isn't paperwork to slow things down—it's your only record of what was promised and what you're paying for.

Scope: Define every room, surface and finish by name

Vague language costs money. "Tile the bathroom" leaves room for dispute about whether the walls behind the toilet get tiled, how high the tiling goes, which surfaces get sealed, and what happens to the floor. Instead, the contract should list each element: "Full wall tiling to 2.4 metres in the main bathroom (including feature wall behind vanity), ceramic floor tiles throughout, grout colour TBD by client."

For kitchens, specify cabinet style, number of doors and drawers, worktop material and dimensions, backsplash coverage, and whether undersinks are included. If plumbing or electrical work is needed, note exactly which outlets are being moved, added or removed. Ambiguity here turns into "that wasn't part of the job" conversations when you're halfway through.

Materials and specifications: Pin down brands, colours and quality grades

The contract should name the actual products being used—not just "ceramic tiles" but the specific tile line, size, colour and finish. Same for paint (colour code, sheen), taps, mirrors, lights, sealants and grout. If you're choosing finishes later, the contract should state a budget allowance and note that any selections above that price are your additional cost.

This protects both of you. It stops the contractor from substituting cheaper materials midway, and it stops you from expecting premium finishes at mid-range prices. When you review a contract, cross-check product names against what you've priced yourself. If something seems cheap relative to what you've seen in shops, ask why.

Timeline and payment schedule: Break the cost into stages, not just a final bill

Never hand over half the contract value upfront. A responsible contractor will ask for a deposit to cover materials (typically 10–20 per cent), then stage payments tied to completion milestones: foundation and structural work done, plumbing and electrical roughed in, tiling complete, finishes installed.

The contract must also state a start date and planned completion date, including any allowance for delays due to load-shedding or supply chain hiccups. If the job stretches beyond a set date, clarify whether that triggers a penalty and whether the contractor covers additional costs (like hiring a plasterer to touch up if work drags on). Payment tied to stages means you're not holding all the financial risk while work sits half-finished.

Defects, disputes and what happens if something goes wrong

Include a section on what counts as defective work and how it's handled. Will the contractor come back to fix loose tiles, uneven grout, paint drips or leaky taps at no extra cost? For how long—a week after completion, a month? If work doesn't meet the contract specs, does the contractor fix it or refund that portion of the fee?

Also clarify who's responsible for site cleanup, protection of existing surfaces, and any damage to your home during the job. If the contractor damages a wall outside the reno area, it should be their cost to repair. If a dispute arises that you can't resolve together, does the contract allow for mediation or arbitration, or are you heading straight to court?

Before you sign

Read the contract line by line. If the contractor resists putting details in writing or says "we don't do contracts," that's a signal to find someone else. Ask for clarification on anything unclear. Get the contractor's full legal name, business registration number (if they're registered), and insurance details in the contract. Check they're registered with the relevant bodies if required in your province.

Once signed, keep a copy and take photos throughout the job to document progress and any concerns. A solid contract won't prevent every problem, but it gives you recourse when one arises.
