Frequently asked questions
Know what your estimate includes before you start.
Are the renovation calculators free?
Yes. All calculators work in your browser, with no account, subscription or payment.
Are prices based on live Canadian contractor quotes?
No. Rates are editable illustrative starting values, not live regional market prices. Request itemized local quotes before committing.
How much extra should I budget for surprises?
A contingency of roughly 10–20% is a common planning allowance; older homes, structural work and hidden conditions may justify more.
Do I need a building permit?
Requirements vary by municipality and scope. Structural changes, certain plumbing/electrical alterations and additions may require permits. Check with your local building department.
Does the calculator include HST?
Yes, there is an editable tax-rate field. The default is 13% for Ontario, but actual tax treatment varies by province and purchase.
