• Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in South San Jose Hills

Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, South San Jose Hills homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost varies depending on several factors, including the location of your home, material, number of windows, size, type and more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in South San Jose Hills.

Something else that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window installations, there are generally two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can advise you on the best type for your project. In South San Jose Hills, the decision will mostly be based on how much damage there is currently and how old your existing frames are.
