This was a Sydney area commercial carpet repair job. The damage was made by knife cuts in carpet caused by painter when removing plastic that was protecting the carpet. The cuts were made with a Stanley knife.
On this job we had to use the invisible mending technique to replace a cut out piece of the damaged carpet with an undamaged piece of carpet we were able to find.
As the units are brand new if we were unable to make invisible the whole unit needed to be replaced at huge costs to the tradesperson.
