Frequently Asked Questions — General Contractors in Alvinston
How do I verify a general contractor is legitimate in Ontario?
Ask for proof of general liability insurance and WSIB coverage, check for any trade licences required for the work (electrical, plumbing, gas), verify their business registration, and request references from recent projects in Alvinston or the surrounding Lambton County area.
Do I need a building permit for my renovation in Alvinston?
Most structural renovations, additions, and significant interior changes require a permit from your local municipality. A reputable general contractor will know what permits are needed and will pull them on your behalf before work starts.
How much does a home renovation cost in Alvinston?
Renovation costs vary enormously by project scope. A kitchen or bathroom refresh might run $10,000–$30,000; a full addition or basement finish can range from $50,000 to $200,000+. Always get a minimum of three written quotes and confirm what is and is not included.
What should a contractor's written contract include?
A solid contract should specify the scope of work in detail, materials and brands to be used, start and end dates, payment schedule tied to milestones, warranty on workmanship, and a process for handling changes or overruns. Never pay more than 10–15% upfront.
