Wiper Blade Replacement in Redwood City: Streaks and Skips
Wiper blades are rubber left out in the sun, so they harden and split whether you use them or not, and they usually fail right when the first serious rain arrives. Five Points Tire can check and replace your blades so you are not discovering the problem on the freeway in a downpour.
Wiper blades at Five Points Tire, in short
Five Points Tire checks and replaces wiper blades in Redwood City so you are not discovering the problem on the freeway in a downpour. Blades degrade by sun and age rather than by use, so about a year is the usual working life, and California sun is not kind to them.
Wipers are the part everyone discovers is worn at the worst possible moment, which is the first serious rain after months of dry weather.
That's not coincidence. They degrade in the sun while you aren't using them.
Wiper blades age rather than wear
About a year is the usual working life of a wiper blade, and the clock runs whether you drive or not.
The rubber edge is exposed to sunlight, heat and ozone continuously. It hardens, it cracks, and it loses the sharp edge that does the actual clearing. Parking outside in California sun shortens the year rather than extending it.
So a lightly used set is not necessarily a good set. Mileage has very little to do with it.
Never wipe a dry screen. Running the blades on a dusty windshield with no washer fluid drags grit across the rubber edge, which is exactly what the edge cannot survive. It is the fastest way to ruin a new set.
Signs you need new wiper blades
- Streaks or smears left behind after each pass
- Sections of the screen that the blade skips entirely
- Juddering or chattering across the glass
- A squeaking or scraping noise as they move
- Visible splits, cracks or hardening in the rubber edge
- The blade lifts off the screen at speed
- It has been more than a year since they were changed
What your wipers are telling you
| What you see | What it usually means | How urgent |
|---|---|---|
| Streaking across the screen | The rubber edge has hardened | Book it in |
| Skipping whole sections | The rubber has taken a set | Book it in |
| Juddering or chattering | Arm angle, or stiffened rubber | Book it in |
| Squeaking or scraping | Worn rubber, or grit on the glass | Monitor |
| Smearing even with new blades | Road film and wax on the windshield | Monitor |
| Blade lifting off at speed | Failed arm spring or wrong blade | Soon |
Clean the glass thoroughly before deciding the blades are finished.
What each wiper symptom means
Streaks mean the edge has hardened. Skipped sections mean the rubber has taken a set. Smearing that survives new blades means the windshield is dirty, not the blade.
| What you see | Cause | Fix |
|---|---|---|
| Streaks left behind | Hardened edge no longer conforming | New blades |
| Whole sections skipped | Rubber has taken a set | New blades |
| Juddering across the glass | Arm angle, or stiffened rubber | Blades, or arm adjustment |
| Squeaking or scraping | Worn rubber, or grit on the glass | Clean the glass, then blades |
| Smearing with new blades | Road film and wax on the windshield | Clean the glass properly |
| Blade lifts at speed | Weak arm spring or wrong blade length | Arm or correct blade |
If new blades still smear, the windshield is the problem, not the blade.
What actually kills wiper blades
Dry wiping is the fastest way to ruin a new set.
Running the blades across a dusty windshield with no washer fluid drags grit along the rubber edge, which is exactly what that edge can't survive. One dusty pass does more damage than a month of rain.
Ice is the other one. Scraping with the blades, or peeling frozen blades off the glass, tears the rubber.
Simple habits that double their life:
- Wet the glass first. Always use washer fluid before the blades move.
- Keep the windshield clean. Road film wrecks good blades quickly.
- Lift them off in frost. Or free them with the defroster rather than by pulling.
- Don't use them to clear snow. That's what a brush is for.
- Check the rear blade too. It's used least, so it perishes rather than wears.

When the windshield is the real problem
If brand-new blades still smear, the problem is the windshield. Road film, old wax and grease build into a layer that no blade can clear cleanly.
Cleaning the glass properly, inside and out, is worth doing before you decide the blades are finished. It's free and it's the answer more often than people expect.
Common wiper mistakes to avoid
- Waiting for rain to find out. Check them on a dry day with washer fluid. That's the whole test.
- Blaming the blades when the glass is dirty. Road film produces identical smearing, and cleaning it is free.
- Running them dry. Grit dragged across the rubber edge is the fastest way to ruin a new set.
- Using the wrong length. Too long and they catch the pillar or each other. Too short leaves an unswept band in your eyeline.
- Forgetting the rear. It's used least, so it perishes rather than wears, and nobody notices until they need it.
The bottom line
Test them on a dry day. Wet the glass with washer fluid and watch what they do.
Streaking or skipping means new blades. Smearing with new blades means the windshield needs a proper clean.
Either way, sort it before the first real rain rather than during it.
Wipers are the cheapest item on the list of things that ruin visibility. Clouded headlights do the same job on a dark road, a blocked cabin air filter fogs the inside of the glass, and both belong on the same service schedule, which is what a vehicle inspection works through.

How often should wiper blades be replaced?
- Around once a year for most drivers, and sooner if you park outside in strong sun. They degrade by age and exposure rather than by use, so a lightly used set is not necessarily a good set.
Why do my wipers streak even though they are new?
- Usually the windshield rather than the blade. Road film, old wax and grease build up into a layer a new blade cannot clear. Clean the glass thoroughly and try again before replacing anything else.
Why do my wipers judder across the screen?
- Either the rubber has hardened and is grabbing rather than gliding, or the wiper arm is holding the blade at slightly the wrong angle so it does not flip cleanly at each change of direction. Both are worth looking at rather than living with.
Does it matter which wiper blades I use?
- Size and fitting type matter, because a blade that is too long can catch the pillar or the other blade, and too short leaves an unswept band right in your eyeline. Beyond that, condition matters more than brand. Five Points Tire fits the size and type your car was designed for, which matters more than the brand on the box.
