Smashed Car Window Overnight - Not Sure What to Do? Read This First

You walked out to your car and found a smashed window. Whether it is a break-in, vandalism, or storm damage, the situation is urgent – your vehicle is unsecured, exposed to whatever weather arrives next, and in some cases not safe to drive. Here is exactly what to do, in the right order.

Book Same-Day Replacement →Step 1: Do Not Touch the Glass Yet
Tempered side glass shatters into hundreds of small granules on impact. Before you start cleaning up, document everything thoroughly with photographs. Take shots of the broken window from multiple angles, the condition of the interior, and if items have been taken, the areas where they were kept. This documentation matters for both your police report and your insurance claim.
If someone has clearly been inside the vehicle, do not disturb anything inside until you have photographed the scene.
Step 2: File a Police Report
If the damage is the result of a break-in or vandalism, file a police report before moving the vehicle or contacting your insurer. For non-emergency incidents in Denver, you can file online through the Denver Police Department – you do not typically need to wait for an officer to attend.
Your insurance company will ask for the incident report number when you file your claim. Get this done first and you will avoid a callback later.
Step 3: Check What Is Missing
Before contacting your insurer, make a complete list of anything taken from the vehicle. Personal items stolen from a car may fall under your home or renters insurance rather than your auto policy – keep the two claims separate and note precisely what was where.
Step 4: Protect the Interior While You Wait
If rain is coming or temperatures are dropping, cover the open window before the weather gets in. A heavy-duty garbage bag or plastic sheeting secured firmly with tape will protect your seats, electronics, and interior panels for a few hours. Do not use anything absorbent against the interior surface.
This is a temporary measure only – it keeps the interior protected while you arrange same-day replacement. A smashed side window cannot be effectively patched or partially repaired, and full replacement is required.
Step 5: Book Same-Day Replacement
Side window replacement does not require the adhesive curing time involved in windshield replacement, so you can drive immediately once the new glass is installed. Most jobs are completed within 30 to 45 minutes.
In many cases, fast replacement also helps prevent additional issues such as interior damage or electrical faults caused by exposure.

Can a smashed side window be repaired rather than replaced?
No. Tempered glass shatters completely when it breaks – there is no intact structure left to work with. A smashed side window will require full replacement. The good news is that it is fast: most jobs are done in 30 to 45 minutes, with no cure time required before driving.
How long does side window replacement take?
Most replacements are completed in 30 to 45 minutes. Unlike windshields, tempered side glass does not require any adhesive cure time – you can drive the vehicle immediately after installation.
Will my insurance cover a smashed side window?
Comprehensive auto insurance typically covers glass damage from break-ins, vandalism, and storms. You will likely need a police report number if the damage was deliberate. Competition Auto Glass handles the entire claims process on your behalf.
What if it rains before I can get the window replaced?
Cover the opening with heavy plastic sheeting secured firmly with tape and call us immediately. Interior water damage from an exposed window can cost significantly more to fix than the glass replacement itself. Same-day mobile service is available across the Denver metro.
