A cracked or chipped windshield is frustrating, and it can be tempting to grab a cheap DIY repair kit from the store. Before you open that box, you should know that a do-it-yourself fix can cost you much more in the long run.
At Dixie Auto Glass, we have seen countless failed DIY repairs that turned a small chip into a complete windshield replacement. This guide explains exactly why professional service matters.
Why It Matters
Windshields are critical safety components. According to Transport Canada, your windshield provides up to 60% of the vehicle’s roof strength during a rollover. GlassBYTEs also notes that improperly repaired chips often spread quickly and compromise airbag deployment.
Improper repair, even on a small chip, can compromise this protection.

What Are DIY Windshield Repair Kits?
These kits usually include:
- A bottle of resin
- An applicator or syringe
- Curing strips
- A razor blade
They promise a quick, affordable solution but often do not deliver the clarity, strength, or safety you need. Our stone chip repair service offers professional results you can trust.
5 Reasons DIY Kits Can Be Dangerous
- Incomplete Damage Removal
Small air pockets often remain, weakening the repair over time. - Uncured or Improperly Cured Resin
Without professional UV equipment, resin may stay soft and fail to bond fully. - Limited Effectiveness on Larger Cracks
Kits are only meant for minor chips, not spreading cracks or damage near the edge. - Compromised Visibility
DIY repairs frequently leave cloudy spots or distortion in your field of vision. - Loss of Insurance Coverage
Attempting a DIY repair can void glass warranties or affect your insurance if further damage occurs.
How Much Do DIY Repairs Really Save?
- DIY Kit: $25 to $50
- Professional Repair: $80 to $150
- Professional Replacement: $300 to $600 or more
While DIY kits look inexpensive, they often lead to a full replacement that costs significantly more in the end.
Step-by-Step: How Professionals Repair Chips
- Inspection and cleaning of the damaged area
- Vacuuming air and debris
- Injection of high-quality resin under pressure
- Professional UV curing for maximum strength
- Polishing to restore clarity
Consumer Reports also recommends professional repair for any chip that obstructs the driver’s vision or has the potential to spread. If you prefer expert help, you can schedule windshield repair services to ensure the job is completed to proper safety standards.
