Windscreen Basics: What Every Driver Should Know

Got a chip in your windscreen? Wondering if a wiper blade swap will actually help? You’re not alone. A healthy windscreen protects you from wind, rain, and debris while keeping the cabin quiet. Below we break down the most common windscreen problems, how to handle them, and which wiper blades give you the best visibility without breaking the bank.

Fixing Chips, Cracks, and Full Replacements

First thing’s first: don’t ignore a small chip. Moisture can seep in, turning a tiny flaw into a big crack fast. Most auto shops can resin‑fill chips for under $50, and the job takes about 30 minutes. If the crack spreads beyond the inner third of the glass, you’ll need a full windscreen replacement. In 2025 the average cost in New Zealand sits between $800 and $1,200, parts and labor included. Buying the glass yourself can shave $100‑$200 off the price, but make sure the dealer ships a certified fit‑for‑your make and model.

When you schedule a replacement, ask the tech about the warranty. A good shop offers at least a two‑year guarantee on workmanship and glass integrity. Also, keep the old windscreen if you plan to sell the car – it proves you didn’t hide damage and can help with resale value.

Choosing the Right Wiper Blades for Your Windscreen

Wiper blades are the unsung heroes of windscreen safety. The wrong size or low‑quality rubber can leave streaks, reduce visibility, and even damage the glass edge. A quick check: measure the blade length on the driver’s side and the passenger’s side – most cars need two different sizes. For example, a 16‑inch blade on the driver’s side and a 17‑inch on the passenger’s side is common on compact sedans.

If you’re debating between a 16‑inch and a 17‑inch blade, go with the size the manufacturer recommends. Oversized blades can lift off the glass in heavy rain, creating a noisy flutter that actually reduces wiping efficiency. Budget‑friendly brands at AutoZone and Walmart both sell compatible blades; price differences are usually under $5 per blade, so pick the one with a sturdy frame and a waterproof rubber strip.

When you replace blades, it only takes a minute. Lift the old arm, press the release tab, slide the new blade on, and snap it into place. Test the wipers at low speed first to ensure they sit flush. If you hear chatter or see streaks, the blade might be too long or the rubber could be misaligned.

Finally, remember the legal angle. In New Zealand, driving with broken windscreen wipers is illegal and can attract a fine. If your wipers are cracked, squeaking, or missing entirely, replace them immediately. The same rule applies to clouded or severely scratched windscreen glass – it must provide clear visibility for safe driving.

Keeping your windscreen and wipers in top shape saves you money, avoids tickets, and makes every drive safer. Check for chips every month, replace wiper blades once a year, and don’t skimp on professional glass work. With these simple steps, your car’s front window will stay clear rain or shine.
