Window Warranties

The simpler and more straightforward the replacement window warranty is the better. One surefire way to simplify is to find a company that both manufactures and installs the window. That way you’re covered either way without a debate about whose fault the problem was. Because warranties are only as reliable as the company that makes it, the most important step in finding a quality option is to find a quality window company. A good company will cover all installation-related problems (including labor and materials) for at least three years. Be sure to read the actual warranty and not just take the salesman’s word for what’s in it. Discover more on the basics using our replacement window guide.

“Since the only time you really need a window warranty is when something goes wrong, finding a top-notch manufacturer for project installation not only means that any problems will be fixed but also that there won’t be a problem in the first place. Check references regarding how the company has handled service work for other customers.”

Replacement Window Warranty Factors

Unless you really know a lot about a product or service, it’s hard to determine exactly when you are getting a fair price. There are such a wide variety of window frames and features on the market that you need to do your research first so you can see what the ballpark is and set a budget. You should know what’s available, what the average prices are, and what features may or may not be beneficial for your home and climate.

The Right Features
The type of window and the energy-saving features you choose will have a dramatic impact on the price. Energy-saving and easy-cleaning features will drive up the price. In order to get the best deal in terms of both performance and price, you need to know which of these features is right for you.

However, this still doesn’t make you a window expert. In order to double check that a deal or low price doesn’t mean that corners have been cut at the cost of quality find out more about the company. Does the company have repeat business with customers buying from them time after time? Contact one or two of those customers for referrals. Finally, get the price clearly spelled out in writing.
