Windshield Repair or Replace After Rain | in Redwood City

What Rain Does to a Damaged Windshield

Moisture can seep into cracks and chips on your windshield, weakening the surrounding glass and reducing the effectiveness of repair resins.

When water gets inside, it can cause internal fogging between the laminated glass layers, especially in humid conditions. Temperature changes may also cause micro-cracks to spread further, worsening the damage over time. Additionally, trapped dirt and debris in the crack can prevent proper bonding during a repair, leading to poor results or the need for a full replacement.

In many cases, replacement is the safer option if the damage has been exposed to rain for a while.

Our windshield repair guide breaks down which cracks can be fixed—and which can’t.

Should You Repair or Replace After Rain?

Choose Repair If:

• The crack or chip is small (under 3 inches)
• The glass has dried thoroughly
• Damage isn’t in the driver’s line of sight

Choose Replacement If:

• Water entered the crack or spread the damage
• You see fog, clouding, or glass distortion
• Damage occurred near the edge of the windshield

Our mobile repair service can come to your location once the weather clears, and our techs can evaluate if repair is still possible.

Don’t Fall for These Glass Repair Myths

Many drivers believe rain "seals" chips or that damage won’t worsen once it’s wet. These auto glass myths can cost you more in the long run. Moisture in the crack can prevent proper bonding and lead to a failed repair.

Brands with Special Considerations After Rain

Some vehicles require extra care if a replacement is needed post-rain:

• Subaru models with EyeSight cameras need sensor calibration
• Audi and Mercedes-Benz may include rain sensors behind the glass
• Toyota hybrids often have solar-reflective windshields
• Ford models with advanced trim may require special sealing steps

We match each vehicle’s glass and ensure recalibration where necessary. Learn more in our post on windshield replacement technology.

FAQs – Repair or Replace After Rain

Can I repair my windshield right after it rains?

Only if the glass is completely dry and clean. Moisture trapped in cracks can prevent resin from bonding properly.

What if I delay fixing it until the weather clears?

Waiting can make damage worse. Rain, followed by sun, can expand cracks quickly. We recommend calling as soon as possible to schedule a service.

Will rain affect a new windshield installation?

No. As long as the adhesive is applied in a dry space and allowed to cure properly, replacement can be done safely—even after a storm.
