Listed for homeowners in and around Thorold, 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: Thorold, ON

Of the 24 companies we list here, 8 are in Thorold itself and 16 come from towns including St. Catharines (7), Niagara Falls (3) and Beamsville (1). The companies on this page are rated from 4.2 to 5.0 across 946 reviews; 7 have 50 or more reviews and 19 are rated 4.5 or higher. When customers rate these companies on specific qualities, they most often praise professionalism (95%), quality (85%) and responsiveness (82%).

We count these figures across the companies on this page; hours and prices change, so confirm the details with the company before you book.

Do any of these companies quote without charging?

The free estimate promises less on a multi-trade job, and it is advertised by 6 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.
