Frequently Asked Questions — Interior Demolition in Oshawa
Do older Oshawa homes need asbestos testing before demolition?
Yes — homes built before 1990 in Eastdale, Donevan, and central Oshawa often contain asbestos in vermiculite insulation, vinyl floor tiles, pipe wrap, and popcorn ceilings. We require asbestos testing before any demo on pre-1990 properties and coordinate licensed abatement when present.
Can you do a basement gut-out in an older Oshawa house?
Yes — this is one of our most common Oshawa jobs. Older basements in central and east Oshawa often have lower ceilings, knob-and-tube electrical, and water-damaged framing. Full basement strip to studs and concrete: typically $1,800–3,500 depending on size and what's coming out.
Do you handle commercial strip-outs in downtown Oshawa?
Yes. King Street, Bond Street, and the downtown Oshawa core have older commercial buildings (former retail, offices, restaurants) that need full interior strip before re-fit. We handle ceiling, walls, flooring, electrical disconnects, plumbing capping, and final cleanup for the next trade.
Can you demo a former GM-era property or warehouse in Oshawa?
Yes — we do interior demolition on light industrial and former GM-supplier warehouse spaces in south Oshawa. Common scope: office build-out removal, mezzanine cuts, equipment foundation removal, and concrete saw-cutting for new layouts. We don't do structural exterior demolition.
How do you protect the rest of the house during partial demo in Oshawa?
Floor protection with masonite over high-traffic areas, plastic-sheet walls to isolate the demo zone, HEPA air scrubbers if dust control is needed, and daily clean-up so families staying in the home aren't living in the demo. Standard for Oshawa kitchen renos with families in residence.
