Types of Glass Damage

Damage can be classified into four main categories, based on severity. These are minor, moderate, heavy, and extreme.

Minor damage: the kind which you cannot hang a fingernail in, and is often the result of glass on glass rubbing, as well as sand paper scuffmarks.

Moderate damage: is substantial enough to catch your nail, but not enough to hang the edge.  This can be the result of razor blade cuts or sand erosion.

Heavy damage: can be felt under the touch of a finger, and is easily visible to the naked eye.  This kind of damage is often the result of pet scratches or dragging from moving furniture.

Extreme damage: is severe, the kind which you can easily hang your fingernail in, and can be viewed on the glass at some distance.  Graffiti is often the cause of this type of damage.

The length and depth of a scratch determines the exact process and time required for complete removal.  For minor to moderate damage, scratches that cannot catch your fingernail, glass polishing is often all that is necessary.  A 5” scratch, at this degree would only take from 1-3 hours to remove.  For heavy to extreme, damage that you can hang a fingernail in, a more aggressive glass abrasion with consecutive clearance is required.  A 5” scratch of this severity may take anywhere from 4-6 hours for complete removal.  At this level it is common to expect some amount of distortion because the depth at the bottom of the scratch determines how much glass must be removed to achieve a level plane.
