Home windows

Owning a home gives you a variety of responsibilities. One of those responsibilities does not come around too often but can be costly when it does. That responsibility is window replacement. There are various factors that go into how long your windows will last. This includes the quality of installation by a Denver Window Company, as well as the quality of the material, and how well your home is insulated. New, replacement windows are an expensive purchase that you want to avoid doing so often. This is why you need to be aware of what to look for, and how long they should last.

How Long Does Windows Last?

Typically your windows should last anywhere from 20 to 25 years. If you purchase them from a brand and they are installed by professionals, then they may even last longer. Especially if you keep them in shape. Most brands do not offer a guarantee for longer than five, seven or 15 years. There are specific factors you need to look at when purchasing windows, these include:

  • Materials
  • Insulation
  • Weather conditions around your home


There are two main common types of window materials found on the market, these are vinyl and wood. Both have benefits and downsides to them. For example, vinyl windows can last up to 15 years if they are mid-grade, while premium vinyl windows are known to last from 20 to 25 years. The main difference in the levels of vinyl windows is that there is titanium dioxide within premium vinyl that prevents warping, cracking, or peeling. This also helps them to maintain their structure. These are typically only guaranteed up to seven years, but they are the cheapest you can find.

Wood is another commonly used material for doors and windows. This is because wood is very durable and easy to maintain. Despite this, wood windows do not last as long as vinyl because they can chip, peel, and rot. They are also considerably more expensive than vinyl windows.


When it comes to installation, this is one of the most crucial elements that will extend or increase the durability of your windows. You should always rely on professional help for installation. This will make the lifespan longer, and also reduce the cost of utility bills.


Where you live and the weather your home is subject to will greatly impact the life of your windows. For example, windows that are often in the sun may last for shorter because of the sun breaking down the materials. This is especially true if the windows are of bad quality and installation.
