How Installing Energy-Efficient Windows in Frederick Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Decrease your carbon footprint: In Frederick, you can lower your indirect greenhouse gas emissions by about 460 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Frederick

Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Frederick can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. Costs will vary considerably based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts 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 depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. 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 provide good insulation. Composite frames made using 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 offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to think about whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window within the frame that’s already there. So, instead of removing the whole window and rebuilding it, the contractor will just put 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.
