Replacement windows are only as good as the warranty that backs them up. Limited warranties are just that - they restrict what a company will do to make things right if things go wrong. Look for manufacturers who offer products with at least a 20 year warranty period. Make sure you understand which components are covered and what circumstances might void your warranty.

Going with a name brand product may not be cheap. However, you may be stuck with a worthless agreement if you buy from a company that goes out of business or is sold after you purchase your windows. When this happens, you are likely to get the run around on who is actually responsible for honoring your claim.

That’s also something to take into consideration when it comes to the installation warranty (which is a separate agreement). There are plenty of fly-by-night home improvement “professionals” who will be long gone by the time the defects in their work become apparent. Choose an established installation company that has a reputation to uphold.

A full lifetime warranty that covers your windows for as long as you own your home is ideal. This type of guarantee generally means you can’t be charged any service or repair fees for fixing a defective product. In addition, the warrantor must actually correct the problem and can’t simply refund your purchase price and walk away without your consent.

Some manufacturers may offer to transfer the warranty when you sell your home to a new owner. That’s an additional perk that can increase the value of your investment in replacement windows. Always store your warranties for home improvements with your mortgage documents so everything is in one place when you need it.
