How Installing Energy-Efficient Windows in Dublin Saves You Money

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

• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Dublin

When considering window installation, each company offers different services and prices. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Even though the national average cost of installing a single window is around $600, it can range from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which carry a higher price tag.

It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Dublin homeowners $531+ a year when replacing single-pane windows.

Something else that affects the overall cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, 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 question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you need.
