What Ottawa homeowners ask
Common Basement Renovation Priorities
The same priorities come up across Ottawa basement projects: clear pricing, code-aware planning, and a crew that can take the work from first visit to final walkthrough.
Homeowners planning a legal suite need the number in writing before they commit. The useful quote is itemized, tied to the actual scope, and clear about egress, fire separation, ceiling height, and inspection requirements.
Legal basement suite
Flood work needs a phone-first path. Extraction, structural drying, moisture testing, mold-safe reconstruction, and a prevention fix all have to be handled in order, with no handoff halfway through.
Flood rebuild & SDU
A finished basement should feel like the rest of the house. That means code-correct framing, insulation, electrical, ventilation, flooring, trim, and a schedule that is explained before work starts.
