MURB in Downtown Toronto
Close Up View of Same MURB Showing Staining Below Window Corners

Ever wonder why your building science consultant is always so adamant about proper end- dams at window flashing termination points? As you can see here, the sill flashing is directing a significant amount of bulk water to the brick masonry directly below the window corners. This will result in localized brick deterioration (you can see some deterioration occurring in this photo already). Widespread deterioration will cost $100,000’s to repair throughout the building.

Properly designed and installed end-dams at the sill flashing termination points would force bulk water to shed off the flashing proper, thus reducing/eliminating the staining and deterioration observed in this photo.

Contact RRCL to review, design and oversee your next restoration project. It is, indeed, all in the details!
