Common questions

Full renovation questions answered

Full gut renovations in the Waterloo Region typically run 3 to 6 months of active construction, depending on scope and site conditions. The planning phase before construction, during which we finalize all selections, permits, and the budget, runs 4 to 8 weeks. Your complete timeline is confirmed and locked in writing before we mobilize.
It depends on the scope. For focused renovations affecting one or two areas of the home, remaining in place is usually practical. For full gut renovations affecting all living areas, temporary accommodation is strongly recommended. We discuss this honestly during the planning call and help you plan accordingly.
Yes. We work on home additions throughout Waterloo Region, including Kitchener, Waterloo, Cambridge, and surrounding areas. Additions require building permits from the respective municipality, structural engineering drawings, and site-specific planning. We manage the full process from initial design to permit approval to final occupancy inspection.
Full home renovations in Waterloo Region typically start around $80,000 for a focused scope and run to $300,000 or more for a complete gut renovation with additions or structural changes. The range depends heavily on the size of the home, existing conditions, and finish level selected. We provide a fully locked budget during the planning phase so you know exactly what you are committing to before construction begins.
Yes. Duplex conversions are a service we offer throughout Waterloo Region, including Kitchener, Cambridge, and Waterloo.
