How Long Do Vinyl Windows Last In Texas?

A: Great question! We offer a lifetime warranty on the vinyl components of our frames. So you don’t have to worry about anything ever happening to your vinyl components. If anything does happen to the vinyl—if it cracks, blisters, peels, rots, corrodes, fades, or warps—we replace it at no cost to you.

Honestly, whenever this question is asked it’s usually because the customer is thinking of vinyl products from the 70s. Back then, there was less advancement in the knowledge of vinyl’s characteristics and recycled vinyl was used heavily.

You’d find it in siding, windows, and other products and yes, the results were not good at all. The fact that people still question vinyl windows in San Antonio over 40 years later, tells you how bad it was.

Keyword: WAS. Now, vinyl windows in San Antonio are made with virgin vinyl which doesn’t warp, peel,  or rot. Another reason people ask it is that they assume that since vinyl windows are lower in cost, they must be inferior.

That couldn’t be further from the truth. Are vinyl windows the least expensive? No, but they aren’t the most expensive either. What they are, is a perfect value of durability, style, and efficiency at a reasonable price.

Yes, there are more expensive windows you can buy as well as cheaper windows you can buy. But be careful, cheap is never good, and good is never cheap. On the flip side of that is the fact that high prices don’t always deliver the best value. We’ll touch on that in just a moment though.

Vinyl Windows In San Antonio Are Where It’s At

For most San Antonio homeowners, vinyl windows are hands down, the preferred window material for the region. While there are those gimmicky ads that offer “$100 windows,” they are a joke. They are just enough to pass a building inspection. Other than that, you’d get about the same insulation from a shower curtain stapled to your window openings.

We may be exaggerating a bit, but not by much. Those windows are only $100 for a reason. They’re made of the cheapest materials and have high failure rates. You can forget it if you think you’re going to get a lifetime warranty from those either.

When we install our vinyl windows in San Antonio homes, the homeowner is getting a lifetime warranty. Why do we offer such a generous warranty? Because, in all honesty, we rarely get a claim. So, in reality, it’s really just to emphasize how confident we are in our product. Our windows simply perform, day in, day out—for life, the stats don’t lie.

But, all that aside let’s address the concerns about how long vinyl windows in San Antonio will last.

Made In Texas For Texas Homes

At The Window Source, we take pride in being one of the leading window companies in Texas. Part of the secret to our success is that our windows are manufactured right here in Texas. They are built to careful specifications that are suited for the extreme climates we experience.

No, we’re not talking about blizzards and ice storms—we’re talking bout that Texas HEAT. When it’s 103° in the shade—that’s HOT!

Our windows however are completely unfazed. They still block out the UV rays that heat up the home and the frames don’t warp. What’s the secret to their durability? No secret, we are obsessed with extreme toughness and won’t sell anything less. That obsession results in vinyl windows that you purchase once—that’s all.

If you have lived in San Antonio for at least a few years you know we get extreme heat waves. Imagine if every few years your windows warped forcing you to have to buy new windows all over. So, having windows made in Texas by Texans is more important than you might realize. Having people that are from Texas engineering the windows and then manufacturing them in Texas eliminates issues like:

  • Fading of interiors from insufficient UV protection
  • Condensation builds up on the glass
  • Temperature spikes due to heat transfer
  • HVAC being overworked due to window leaks

How Does Texas Weather Affect Cheap Windows?

Now, let’s say you decided to go with the cheap windows we talked about earlier. Those cheap windows will have issues with even our milder summer days. Again, you’re getting what you pay for. Substandard materials, cheap mechanical components, and low-cost glass—that’s how you make a $100 window.

So what happens? How do these cheap windows only last a couple of years in this Texas weather? Well, let’s take a quick look.

– UV Rays

Most premium vinyl windows in San Antonio will last at least 30 years if properly cared for. They can easily survive our hottest summers and protect you from UV rays. Cheap windows on the other hand offer insufficient protection from UV rays. This causes your interiors to fade fast, not to mention expose your family to excessive UV rays.

– Humidity

Texas is known for shifting from a dark thunderstorm to 98° degrees with full sun in a matter of 20 minutes. That means the humidity is off the charts. When cheap windows use cheap metals for the locks and balances, all that moisture will rust them out. Our windows use stainless steel locks and balances that last for decades at the least.

– Hail & Extreme Winds

We are known to get hail that can do some serious damage along with high, whipping winds. Cheap windows get shredded in these conditions. Our windows are built from thick virgin vinyl that goes through ridiculous impact testing.


Our windows are Texas Strong and built to handle anything. We wouldn’t settle for anything less than the best to stake our reputation on.
