What separates a great general contractor from a cheap quote, and the questions worth asking before you sign.
On a months-long project, weekly updates and a clear point of contact matter as much as pretty photos. Ask how they keep clients informed and who you call with questions.
Reputable Ottawa contractors tie payments to milestones, never a large sum up front. Be cautious of anyone asking for most of the money before work begins.
Additions, structural changes, and many basement finishes need City of Ottawa permits and inspections. A good contractor handles this; get it in the contract.
Scope, materials, allowances, timeline, and change-order process should all be in writing. A detailed contract protects both sides when something inevitably shifts.
