About TNS Construction

TNS Construction is a family-owned renovation business based in Newmarket, Ontario. We started with a simple goal: deliver honest workmanship, clear communication, and finishes that hold up through Ontario seasons.

From balcony restorations and waterproofing to drywall, fencing, painting, and flooring, we take on the scopes homeowners and general contractors depend on — with one accountable team from estimate through punch list.

Being local to Newmarket means we know York Region and GTA building conditions, permit expectations, and the details that separate a rushed job from work done properly. We treat every property like our reputation depends on it — because it does.

Whether you are planning a single trade or coordinating a multi-phase renovation, we provide written scope, realistic timelines, and milestone-based billing so there are no surprises.
