How Installing Energy-Efficient Windows in Sunnyvale Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Sunnyvale, that’s about 117 pounds per year on average.
• Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Sunnyvale

Each window installation company provides varying services and has varying price points depending on a few factors.

How Much Do New Windows Cost?

Although the national average cost of installing one window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window replacement company should be able to help you decide what’s best for your needs. In Sunnyvale, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.
