How Installing Energy-Efficient Windows in Mountain View Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

• Reduce your carbon footprint: In Mountain View, you can lower your indirect greenhouse gas emissions by about 117 pounds per year once you switch to energy-efficient windows.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $562 annually on your energy bills in Mountain View.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Mountain View

Each window replacement company offers varying services and has different costs depending on a few factors.

How Much Do New Windows Cost?

Typically, Mountain View homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Mountain View homeowners $562+ a year when replacing single-pane windows.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when considering a window replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installer should be able to help you figure out which type of installation you should get.
