We're in a condo in Westboro and worried about fumes during refinishing — how disruptive is it?

Floor refinishing fumes are a legitimate concern, especially in a condo setting where ventilation is more limited and neighbours are close by. The good news is that dustless sanding systems have dramatically reduced the particulate issue, and water-based finishes have made the fume situation much more manageable than it used to be.

The two-phase disruption breaks down into sanding and finishing. Modern dustless sanding systems capture 95%+ of dust at the source, so you won't be dealing with a fine layer of sawdust coating everything in your unit. The finishing phase is where fumes become the bigger concern — and this is where your choice of finish matters enormously.

Water-based polyurethane is the clear winner for condo living. It has a much lower VOC content than oil-based finishes, dries faster (2-4 hours between coats vs. 8-12 hours for oil-based), and the odour dissipates within 24-48 hours. You can typically re-enter the space within 24 hours of the final coat. Oil-based finishes produce stronger fumes that linger for 3-5 days and can permeate into neighbouring units through shared ventilation — something your condo board may have opinions about.

In Westboro specifically, most condo buildings have rules about renovation work hours, noise, and sometimes VOC-emitting products. You'll want to check your condo corporation's bylaws before booking the work — some buildings require advance notice to management, protection of common area hallways during material transport, and may restrict certain finish types. Your contractor should be familiar with these requirements.

Practically speaking, plan to vacate your unit for at least 2 full days with water-based finish — longer if you have young children, pets, or anyone with respiratory sensitivities. Keep windows open if possible and run ventilation fans to accelerate off-gassing.

For a project like yours, sand and refinish runs $3–$6 per sq ft in the Ottawa market, with water-based finish sometimes adding a small premium over oil-based. It's worth it for the faster turnaround and lower disruption in a condo environment.
