A chipped windscreen can happen suddenly when a stone or piece of road debris hits the glass. The damage may look small, but vibration, temperature changes and continued driving can cause some chips to spread into cracks.
The right response depends on the size, location, depth and type of damage. A small chip may be repairable, while more serious damage may require the entire windscreen to be replaced.
What Causes a Chipped Windscreen?
Most windscreen chips are caused by something striking the glass while you’re driving.
Common causes include:
- Stones thrown up by other vehicles
- Gravel on the road
- Debris from trucks
- Small objects falling onto the car
- Road construction debris
- Minor impacts
The faster you identify the damage, the easier it is to have it assessed before it becomes a bigger problem.
Can a Chipped Windscreen Be Repaired?
In many cases, yes.
A small, localised chip can often be repaired using specialist resin. However, there is no single size that guarantees a repair will be suitable.
A technician will normally consider:
- Size of the chip
- Depth of the damage
- Type of chip
- Location on the windscreen
- Whether cracks have started spreading
- Whether the driver’s visibility is affected
Damage close to the edge of the glass or directly in an important viewing area may require replacement instead.
What Does Windscreen Chip Repair Involve?
Professional chip repair generally involves cleaning and preparing the damaged area before specialist resin is introduced into the chip.
The technician works to remove trapped air and fill the damaged section with resin before curing it.
The repair may leave a small mark behind. The purpose is not necessarily to make the damage completely invisible but to stabilise the damaged area and improve the condition of the glass.
Should You Drive With a Chipped Windscreen?
Don’t ignore a chipped windscreen simply because the car is still driving normally.
Road vibration and changes in temperature can cause existing damage to develop further. A small chip can therefore become a crack that requires a much more extensive repair.
If the damage is directly in front of the driver or is affecting visibility, have it assessed before continuing normal driving.
What If the Chip Has Already Become a Crack?
Once a chip has developed into a crack, the repair options can become more limited.
A short crack may sometimes be repairable depending on its location and characteristics, but long cracks, edge damage or damage affecting the driver’s main viewing area may require windscreen replacement.
Don’t try to determine this from appearance alone. A proper inspection is more reliable.
Chipped Windscreen in Nigerian Driving Conditions
Nigerian roads can expose vehicles to plenty of dust, gravel, potholes and road debris. Busy roads with trucks and commercial vehicles can also increase the chance of small stones being thrown towards vehicles behind them.
If you’re driving regularly around Lagos, Abuja, Ibadan, Ilorin or other busy areas, inspect your windscreen whenever you wash or clean the vehicle.
A small chip is much easier to notice when the glass is clean.
What Should You Do Immediately After a Chip?
If a stone has just hit your windscreen, avoid touching or picking at the damaged area.
Keep the area as clean and dry as possible and arrange an assessment when convenient.
If you have to continue driving, avoid unnecessary impacts such as rough roads and potholes where possible. Don’t pour very hot water onto damaged glass, as sudden temperature changes can place additional stress on the windscreen.
Can You Use a DIY Windscreen Repair Kit?
DIY repair kits are available, but the result depends heavily on the type and condition of the damage and how correctly the kit is used.
A professional technician can assess whether the damage is actually suitable for repair before attempting to fill it.
This is particularly important when the chip is close to the edge of the glass or in the driver’s main viewing area.
When Does a Windscreen Need Replacement?
Replacement may be necessary when:
- The damage is extensive
- The chip has developed into a significant crack
- The crack reaches the edge
- Multiple areas are badly damaged
- The driver’s visibility is affected
- The glass has suffered structural damage
- A professional determines that repair is unsuitable
A replacement should match the vehicle correctly, including its dimensions, mounting requirements and any integrated features.
Check the Windscreen After a Long Journey
If you’ve travelled on rough or heavily trafficked roads, inspect the windscreen afterwards.
Look for:
- New chips
- Small cracks
- Spreading cracks
- Scratches
- Areas affecting visibility
A quick inspection can help you identify damage before it becomes more difficult to deal with.
Don’t Ignore Windscreen Wipers
Windscreen wipers are also important because worn or damaged blades can reduce visibility and may contribute to scratching the glass.
Replace worn blades when necessary and keep the windscreen washer system working properly.
A clean windscreen makes small chips and cracks easier to spot and also helps maintain clear visibility while driving.
Getting Your Car Ready for Travel
A windscreen check should be part of preparing your car for a long-distance journey. Along with the glass, inspect your tyres, brakes, lights, battery and fluids before setting off.
If a windscreen problem means you need to change your travel arrangements, Travo.ng can help with relevant transport, travel and logistics coordination while the vehicle is being repaired.
The main thing with a chipped windscreen is not to wait for a small problem to become a large crack. Have the damage assessed early so you can determine whether a simple repair is suitable or whether replacement is necessary.
