Listed for homeowners in and around Oshawa, ON, these 24 companies take on multi-trade work, from a basement build-out to a full renovation. What each one says about licensing, hours and the work it takes on comes from its own website; ratings and quotes come from public reviews.
Area overview: Oshawa, ON
Of the 24 companies we list here, 23 are in Oshawa itself; the other one does not publish an address. The companies on this page are rated from 4.1 to 5.0 across 525 reviews; 1 has 50 or more reviews and 21 are rated 4.5 or higher. When customers rate these companies on specific qualities, they most often praise professionalism (96%), quality (90%) and responsiveness (82%).

Do any of these companies quote without charging?
The free estimate promises less on a multi-trade job, and it is advertised by 13 of the 24 companies here. Free normally buys a walk-through and a ballpark figure. A real price takes measuring, trade pricing and desk time, so design-build firms often charge for that stage and credit it against the work if you sign.
