One group · Three specialized solutions · Ontario
Renco Group delivers commercial and residential caulking, waterproofing and expansion joint work — plus rapid-response service and building envelope advisory — through three specialized divisions.
The group
Renco Group works across three divisions. Each one runs on its own discipline and schedule — and behind all three is the same standard of workmanship and the same people to call.

Rapid-response crews for smaller, time-sensitive scopes: service calls, localised repairs and short-notice work.
Expertise. Strategy. Growth
Advisory support before the work starts: condition reviews, scope definition and repair strategy.
Why Renco Group
Caulking, waterproofing and expansion joints are small line items on a construction budget and the first thing to fail when they are rushed. Our approach is built around the parts of the job that decide how long the work lasts.
Joints are cut out, prepared and tooled properly. The finished bead is consistent, and it is the same standard on the back elevation as on the front entrance.
From curtain wall perimeters and parking decks through to windows, doors and exterior trim on a single home — the same crew handles both ends of the range.
Realistic sequencing, clear scheduling and communication that keeps general contractors and property managers informed rather than chasing.
Sealants, primers and membranes are selected for the substrate and the movement each joint has to absorb, and installed to the manufacturer’s requirements.
Corners, terminations, penetrations and transitions are detailed first, because that is where water actually gets in.
Work areas are protected and left clean — a requirement on occupied buildings, and simply how the job should be done everywhere else.
What we do
Every building has joints. Ours is the trade that closes them — and keeps them closed while the structure moves, settles and weathers.
Project types
Curtain wall perimeters, parking decks, plaza waterproofing, movement joints and residential weather sealing — across commercial, institutional, industrial and residential buildings.
Our approach
A sealant joint is only as good as the preparation behind it. We would rather spend the extra hour cutting out failed material and priming the substrate than come back in two years to do the same elevation twice.
Where we work
We take on commercial and residential work throughout Toronto & the GTA, Hamilton, Niagara, Ottawa and surrounding Ontario communities.
