Yes — especially in a climate like Milwaukee’s.
Cold weather is one of the most common reasons small windshield chips turn into large cracks. Temperature fluctuations cause glass to expand and contract, putting stress on already weakened areas.
Why Winter Is Hard on Windshields
In Wisconsin, winter brings a combination of factors that increase crack spreading:
- Freeze-thaw cycles
- Sudden defroster heat
- Road vibration on rough pavement
- Ice scraping
- Road salt and debris
When moisture enters a chip or crack and temperatures drop below freezing, the water expands. This expansion forces the crack wider — sometimes dramatically.
What Happens Overnight?
Many drivers are surprised when a small chip they noticed the day before suddenly becomes a long crack by morning.
This typically happens because:
- Overnight freezing expands trapped moisture
- Glass contracts in extreme cold
- Morning defrost heat creates rapid temperature contrast
These conditions place stress on the damaged area, causing it to grow.
How to Prevent Crack Spreading in Winter
If you notice a chip during winter:
- Avoid blasting hot air directly on it
- Do not pour hot water on icy glass
- Avoid aggressive scraping over the damaged area
- Schedule repair as soon as possible
The sooner a repair is performed, the more likely the damage can be stabilized.
