We gather preliminary details about your basement project.
We provide a ballpark estimate over the phone or via email.
If the estimate fits your budget, we schedule a 1-hour visit to take measurements and selections. After your selections, we send a detailed quote for approval.
We apply for necessary permits (approval from the City can take anywhere from 2 - 8+ weeks) and set a tentative start date.
Once permits are approved, materials are ordered, and work begins.
Your basement is completed within 4-8 weeks, though legal suites may take longer.
