How Installing Energy-Efficient Windows in Lathrop Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, including:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.

Estimated Cost of Window Replacement in Lathrop

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Although the national average cost of installing one window is around $600, it can range anywhere from $200 to $1,200. This is because of the fact that window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Lathrop homeowners $690+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the full window, including the trim, sill and frame. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you decide which type of installation you need.
