Glass Damage - Causes, Repair, and Prevention

Causes, Repair, and Prevention of Glass Damage

Glasses are essential to a structure because they let in natural light and improve its appearance. But like any other material, glass is subject to wear and tear over time. Broken glasses affect more than just one area of your house. Thus, glass repair ought to come first at all times.  It's only a way to preserve your living area and repair chips and cracks.

Feeling uncertain about how to handle glass damage? Don't fret. We're here to equip you with the knowledge and understanding of glass repair, from identifying the types of breakage to understanding the reasons behind them and providing maintenance tips. This will empower you to make informed decisions and take proactive steps to maintain your glass surfaces.

Glass Breakage Types

Understanding the four types of glass breakage and their identification tips is crucial for homeowners and property managers. This knowledge will empower you to identify the cause of damage and choose the most appropriate repair technique for your home or commercial setting.

Pressure Breaks

Stress cracks begin close to the window's edge and extend outward. Temperature-related factors, such as excessive heat or cold, are frequently the source of stress cracks. Heat-strengthened glass can develop stress cracks. Look for a chip at the edge of the glass, called an oyster, to distinguish between a stress crack and other glass breaks brought on by edge damage.

Impact Breakage

An abrupt hit, such as a ball thrown quickly at a glass window, can produce impact breaking. The object's speed, in addition to its size and thickness, affects the pattern of glass breaking. This kind of glass damage results in the formation of a centre point of impact breaking and lines extending outward from the perimeter.

Unplanned or Spontaneous Breaking

What is spontaneous breaking? Tempered glass that breaks spontaneously, appearing to happen for no apparent reason. Although it happens infrequently, nickel sulfide inclusions, small rocks that have remained in the glass and have a natural tendency to expand to their original size, can also cause spontaneous fracture.

Edge Crack

Breaking tempered glass might result in edge damage. When the glass edges are damaged, for instance, chipped during shipping or installation or sliced into smaller panels, they break on their own.

Common Reasons for Unintentional Glass Breakage

The professional designs the glass to be strong. However, it can sometimes break unexpectedly. If this happens to you, remember it's often not your fault. Glass breakage is common, and understanding its causes can help alleviate any anxiety or stress you may feel.

Why, then, does glass shatter?

More accurately, what breaks the glass on its own?

The following are the most frequent causes of unexpected glass breakage. The below section will cover these in more detail.

Heat Cracks

Glass can break on its own when temperatures are too high (above 150 C) or fluctuate too quickly (above 15 C). Glass expands when it becomes hot. It pulls inward and creates stress spots that cause cracks when it rapidly cools down again, preventing it from contracting at the same rate.

Old Creased Glass

Imagine an old property! Did you see its broken windows? It is a common scenario in a weathered house. Glass windows require repair or replacement like other things in an old house. Glass windows can become shabby and creased for daily use.

Poor Installation and Glazing

Glass is prone to breaking if it isn't installed perfectly with a robust and supportive foundation and sealed to keep out moisture and ventilation. Glass can break due to excessive weight from the glass itself or pressure from the wind and environment.

What Kinds of Glass Repair Techniques Are There?


Resin Injection

Resin injections can fill the Glass chips. The resin is injected into the fissures to seal them. Next, you can use UV radiation to cure or harden the raisin. This technique prevents the crack from getting worse by filling it.

Polishing Glass

Glass polishing can fix glass scratches. It buffs out the scratches with specialist glass polishing professionals. The procedure involves dabbing the substance onto the blemish until it is eliminated.

Application of Window Film

Window film is used to fix minor fractures and other damage. Sticky window films add a layer of protection to the glass, improve security, and offer UV protection.

Replaced Double-Glazed Unit

Fogging between double-pane windows can be fixed by replacing the double-glazed unit. The impacted double-glazed unit may change using this technique. It helps in restoring the window's insulating qualities.

Glass Replacing

Replacement glass is used to fix large cracks, broken glass, and damage that cannot be fixed. The process entails replacing the entire glass with a new one.


Re-caulking can fix damaged seals on glass doors and windows. This technique uses fresh sealant after the old caulking’s removal, guaranteeing an airtight and waterproof seal.

Glass Edge Restoration

The glass edge repair technique can fix cracks or fractures along the glass edges. This process refines and smooths out the chips or cracks using specialised equipment, contributing to ensuring safety and strengthening glass edges.

Advice for Maintaining Glass

Make Use of the Proper Cleaning Supplies

Frequent cleaning is necessary to keep glass functional and aesthetically pleasing. First, wipe out any dirt or debris, then wipe the surface with a light detergent. Steer the cleaners that contain phosphoric or hydrofluoric acid because they can lead to corrosion. Lastly, before using the glass again, make sure it is scorched using a cloth.

Avoid Using Sticky Materials or Tapes

To maintain your glass furniture, avoid using sticky or tape materials. These can damage or stain the glass's texture. If necessary, choose removable products with a warning.

Stop Kids from Playing on Surfaces Made of Glass

If you want your glass to last longer, keep kids from playing with it. Do not set playthings on glass furniture or tea tables that can break accidentally. To reduce the chance of damage, consider getting kids' tables and chairs made of plastic.
