Why homeowners and builders choose GSS

We pour footings, foundation walls and slabs, underpin basements and frame homes from Hamilton to Oshawa and north to Barrie and Orillia. Pick your area below, or send your address and we’ll confirm the same day.

01

Your schedule stays on track

We own our forming system, so your pour never waits on a rental yard or another crew’s calendar.

02

One company, footing to roof

Concrete and framing under one contract. No gap between trades, and no arguing over walls that are out of square.

03

Built right, inspected at every stage

Built to your engineered drawings. Footings are inspected before every pour, and underpinning follows the engineer’s sequence.

WSIB cleared with $5 million in liability insurance. Certificates on request, before we start.
