Rope access glazing

We have a certified experienced abseiler on staff to reach high windows that have poor access.  Unfortunately, some high rise buildings don't have practical and simple systems in place to enable a high window to be reglazed.  While the building is being constructed glazing can be a simple process, as you have a crane and scaffolding erected on a secure site.  Reglazing however can become extremely difficult after the building has been finished.  Sometimes the cheapest and easiest method of fixing a cracked or broken window is for a glazier to abseil down the side of the buiding.
