Of the 24 companies we list here, 6 are in Keswick itself and 18 come from towns including Barrie (6, 21 km), East Gwillimbury (2, 14 km) and Newmarket (2, 22 km). The companies on this page are rated from 4.3 to 5.0 across 1,693 reviews; 12 have 50 or more reviews and 22 are rated 4.5 or higher. When customers rate these companies on specific qualities, they most often praise professionalism (96%), quality (91%) and responsiveness (81%).

The services the companies on this page list most often on their websites are asbestos abatement (2), biohazard remediation (2), commercial loss (2), content cleaning (2) and deep cleaning (2). 8 show a licence on their websites. 8 have ten or more years of experience, the longest 21 years. 6 offer emergency call-outs; 2 offer financing or payment plans; 14 give free estimates and 5 are family- or locally-owned. We count these figures across the companies on this page; distances are straight-line, and 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 14 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.
