How Installing Energy-Efficient Windows in Santa Clara Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:

• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
• Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Santa Clara

Windows come in various shapes, styles and purposes, so costs and services will vary remarkably depending on your project. Below, we detail the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

Though the national average cost to install a single window is around $600, it can range anywhere from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which carry a higher price tag.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $562 a year on your energy bills in Santa Clara.

Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most 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?

The first step of a replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable damage. Because these installations are more involved, they will raise the total cost. Pocket installations are on the simpler end and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re unsure which type of window installation service you need, your installer should be able to help you out. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.
