What a renovation quote should include

The minimum for any trade

A quote you can compare has at least four cost categories: materials, labour, permits and disposal, and the contractor's overhead and profit, even if the last is folded into rates. It names the products by brand and line, states what is excluded, and gives a written warranty. A single lump sum cannot be checked.

• Legal business name, address, HST/GST number, licence where the province requires one
• Proof of liability insurance and WSIB or WorkSafe coverage
• Scope in measurable terms: square feet, squares, openings, tons, linear feet
• Products by brand and model or series
• What is excluded, in writing
• Permit responsibility and cost
• Payment schedule tied to milestones, with a deposit under 10 to 15 percent
• Warranty on workmanship, separate from manufacturer warranties
• Start date, duration and change-order rate

Roofing

Tear-off and disposal with layer count, synthetic underlayment, ice and water shield location, the shingle line, flashing, ventilation, a per-sheet price for decking, and cleanup. Permits are not required for like-for-like asphalt in most Canadian cities, so a permit line on a simple re-roof deserves a question.

Heating and cooling

Exact model numbers, capacity from a heat-loss calculation, efficiency rating, cold-climate rating for heat pumps, removal of old equipment, line set and pad, thermostat, electrical work, permit, commissioning, and separate parts and labour warranties.

Windows and doors

Every opening by size and type, manufacturer and series, glazing, retrofit or full-frame install, trim and capping, disposal, screens and hardware, and both product and installation warranties.

Bathrooms and kitchens

Demolition, plumbing and electrical with fixture and circuit counts, waterproofing product, tile and flooring square footage, cabinets by maker and grade with linear feet, countertop material and square footage, who supplies fixtures and appliances, design drawings, permit, and a stated contingency.
