How Installing Energy-Efficient Windows in Gladstone Saves You Money

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

• Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• 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.
• Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Gladstone

When looking into window installation, each company provides varying services and costs. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But prices differ 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, which will add extra costs to your project.

It’s important to note 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 Gladstone homeowners $395+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

The first step when considering a window installation is to figure out whether you want a full-frame or pocket installation.

Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the entire window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

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