How Installing Energy-Efficient Windows in Round Rock Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
• Decrease your carbon footprint: In Round Rock, you can cut your indirect greenhouse gas emissions by about 507 pounds per year once you install energy-efficient windows.
• Save money on electricity bills: After you upgrade 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 home.

Estimated Cost of Window Replacement in Round Rock

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

How Much Do New Windows Cost?

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

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your installers will replace the full window, including the trim, frame and sill. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company can advise you on the best type for your project. In Round Rock, the decision will mostly be based on how much damage there is currently and how old your existing frames are.
