Render Construction self-performs every commercial masonry scope, from structural block, veneer and structural brick to natural and manufactured stone and restoration, for general contractors, developers and institutions across London and Southwestern Ontario. One crew under one foreman on one schedule means no sub-subbing, no handoffs, and a number that holds from takeoff to close-out.
The backbone of schools, warehouses and mid-rise buildings. Render crews lay structural blockwork at a pace that keeps GCs on schedule, with load-bearing, core-filled and reinforced conditions handled in-house.


Veneer and structural brick for residential, commercial and institutional builds. Clean lines, consistent coursing, tight tolerances.
Natural and manufactured stone for facades that need to make an impression. From restaurant fronts to condo lobbies.

Some of downtown's best-kept buildings are ours. Heritage brick repair, repointing, and full exterior restoration that brings older structures back to standard without losing their character.
BeforeMasons and labourers across Southwestern Ontario. We staff to your schedule, not the other way around.
A dedicated estimating team and professional quantity surveyor. Detailed takeoffs, fast turnaround, no surprises.
Uninterrupted foreman presence on every job. One point of contact from mobilization to close-out.
Full written policy program covering every wall type and site condition we work. Documentation ready when your GC asks.
Chris Warren founded Render Construction in 2014, but his start in masonry came long before that, on the wall, laying brick for a Windsor firm. A Windsor native, he trained through a brick and stone mason apprenticeship and earned a construction engineering technology management diploma from Fanshawe College, sharpening the estimating and management side during slow winter months in the office. With his wife and business partner Vanessa, Chris won Render's first job, the masonry package for Old Oak's Pomeroy Place in London, and built the company from a single trailer into one of Southwestern Ontario's largest masonry contractors: a team of more than 100 that has delivered industrial, commercial, institutional and residential projects across the province.
