How Installing Energy-Efficient Windows in Trumbull Saves You Money

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

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• 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.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.

Estimated Cost of Window Replacement in Trumbull

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

How Much Do New Windows Cost?

Typically, homeowners in Trumbull can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. Costs will differ considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Trumbull homeowners $441+ per year after replacing single-pane windows.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most 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 question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise 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. A pocket installation involves replacing a window without taking out the whole frame, which is usually less expensive than a full-frame installation.

If you’re unsure which type of window installation service you need, your installer can assist you. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.
