What debris and materials are removed during the rough clean phase in Ottawa?

The rough clean phase on an Ottawa construction site removes a surprisingly wide range of materials, and understanding what is involved helps you evaluate contractor quotes and ensure nothing gets overlooked. The debris falls into several categories, and some of it needs different handling than the rest.

Wood waste is often a large category by volume. This includes framing offcuts, plywood and OSB scraps, lumber ends, wooden blocking, temporary bracing, form boards from concrete pours, and wood packaging from material deliveries. Drywall scraps are another big contributor — mis-cut sheets, cutouts from electrical boxes, plumbing penetrations, and window openings, plus the fine gypsum dust that coats everything within range. Ask the cleaning company how and where construction waste like this will be disposed of.

Insulation waste varies depending on the type used. Fibreglass batt offcuts and loose-fill overspray are common, and spray foam insulation leaves hardened overspray and trimmed excess that needs to be scraped and collected. With Ottawa's cold winters, homes tend to be well insulated, so there can be a fair amount of this waste. Metal waste includes electrical wire scraps, copper and PEX pipe cuttings, HVAC duct offcuts, metal strapping, joist hangers that were not used, and the many nails, screws, and staples that accumulate on floors and in corners.

Packaging materials are often underestimated. Every window, fixture, appliance, and material delivery comes wrapped in cardboard, plastic, foam, and strapping, and on a new build that adds up quickly. Concrete and masonry debris — mortar droppings, chipped brick or block, concrete splatter from foundation work, and grout residue from tile installation — takes heavy-duty collection and can be one of the most labour-intensive materials to remove from floors and surfaces.

Ottawa's seasons add their own mess. Mud tracked in from the lot can stick to concrete slabs and subfloors. During spring thaw, debris that was trapped under snow and ice reappears and needs to be collected. Salt and de-icer tracked in during winter should be cleaned up so it does not mark finish materials. Snow and ice that get into an unfinished structure can leave meltwater behind for the crew to deal with.

Hazardous materials need special attention. Leftover paint, solvent containers, adhesive tubes and caulking waste should be kept separate from regular debris, since the City's Trail Road landfill does not accept hazardous or liquid waste. In renovations of older homes, old materials can contain asbestos and old paint can contain lead. Suspected asbestos is a job for an abatement contractor, not a cleaning crew; have it tested before cleanup begins. Ask the cleaning company how it sorts debris and where each type goes, and ask whether its workers have WHMIS training for the products they use on site.
