Technician on ropes fitting a flashing on a white wall

Flashing installation

Flashing sends water back outside the wall. We install and repair head, sill, parapet and through-wall flashings from ropes, and rig lifts for lengths too long to carry through a suite.

Flashing we install

On new builds we often follow the glazier. On existing buildings we replace what leaks and leave the rest alone.

  • Window head and sill

    Drip edges and end dams that keep water out of the frame.

  • Parapet caps

    Caps re-sloped to the roof, with sealed laps and clips.

  • Through-wall

    Slab-edge and shelf-angle flashings lapped under the membrane.

  • Corner cups and trims

    Small closures at corners and transitions between claddings.

  • Repairs

    Open laps resealed and loose sections refixed.

Questions about flashing installation

Short answers. Call us for the long ones.

Can you fabricate the flashing?

We measure and install. Flashing is bent to our site measurements by a sheet metal shop, in the gauge and colour your specification calls for.

How do you get long pieces up the building?

With a hauling system rigged from the roof. Lengths that will not fit an elevator travel up the outside under control.

Will you seal the laps?

Yes. Laps are sealed and end dams formed, because most flashing leaks start at a lap or an open end.

Do you work for glazing contractors?

Yes. We install flashing as a subtrade behind window wall and curtain wall crews on new towers.

Flashing work on site

Long flashings ride up the façade on a rope system. Short ones go over the edge with the technician.
