The question of how long is a lifetime warranty for a replacement window might sound simple. Like so many things in this business, window companies have found a way to make it complicated.

There is a claim circulating that a lifetime warranty on a vinyl window (maybe any window) is actually only 7 years. The window salesman may make many claims about this “fact”, but you can be confident that none of them are true.

The salesman will usually tell you that this is a local issue.  For example, he may say something like, “did you know that in this state a lifetime warranty is only actually 7 years?”  Unfortunately, he’ll never have any evidence that the claim is true, because it’s not.

There is really only one company that we’re aware of frequently making this silly claim. As you’d probably expect they do it because they offer a shorter warranty than most companies.

Not only do they offer a shorter warranty, they also offer a higher price. That’s their problem.

Why would they do that?

I can only guess that they think it’s their only strategy. If you were tasked with selling a product for a lot more than your competitors and you offered a shorter warranty you’d have only a few options.

Unfortunately the option they take is to lie to their customers.  Strange choice.

So, how long is a lifetime warranty?

Luckily, we don’t need to guess or take anyone’s word for it.  When it comes to warranties we can just read them to see what they say.  As you can see in the video above we used 2 examples of regular old vinyl windows, not fancy models.  They both have warranties that are good for as long as you own the house.

Then, the warranties are transferable when you sell the house.  Lifetime warranties are good for as long as you own the house.

There is nothing complicated about it, no tricks or gimmicks.  You can just read the warranty to see that.

How might a company try to prove that lifetime warranties are actually shorter?

We made this video after receiving a comment on the site from a reader.  He sent in an article from the Denver Post about a person who thought she had a lifetime warranty on her windows. You can find it here.

This is the exact type of article a window company might show you to mislead you about warranties. 

The customer in the article had a problem after a number of years and the manufacturer told her the windows only had a 5 year warranty, not a lifetime warranty so they would not service her windows.

Now, it sounds like the original widow salesperson may have mislead the customer by telling her that the windows had a lifetime warranty that covered glass breakage when they did not.  That type of thing most certainly can happen.  Window salespeople may lie to you.

The problem she had was with the salesperson, not with the warranty.  The windows she bought did not have a lifetime warranty that covered glass breakage which is why she didn’t get any coverage.  There was absolutely no issue with the lifetime warranty not providing coverage.

So, if you hear a window salesperson tell you that lifetime warranties are not actually good for a lifetime ask them for some proof and post a comment here to let us know how they justified that claim.  I love seeing how they try to justify their silly claims.
