Estimates, quotes and contracts

Step-by-step estimating, worked budgets, contingency, comparing quotes, contracts, deposits, holdbacks and contractor checks.

This section turns a rough idea into a budget you can defend and a contract you can rely on. The estimating method walks through scope, quantities, unit ranges, one-time costs, contingency and tax, and the worked examples apply it to a basement secondary suite and a whole-home refurbishment, with the arithmetic shown.

Once you have a budget, the next guides help you ask for and compare quotes on the same scope, read the contract before you sign it, set a sensible deposit and payment schedule, keep the statutory holdback where your province's lien act requires it, and check licensing, insurance and workers' compensation status.

The calculators do the arithmetic: the renovation cost estimator for a low-to-high range, the sales tax calculator, the contingency calculator, the holdback and payment calculator and the quote comparison checklist. All examples are illustrative; contracts and deadlines differ by province, so check the official sources listed in each guide.
