How Installing Energy-Efficient Windows in Collinsville Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Collinsville, that’s about 642 pounds per year on average.
• Save money on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in Collinsville

Each window installation company provides varying services and has different price points based on several factors.

How Much Do New Windows Cost?

Although the average cost of installing one window is around $600, it can range anywhere from $200 to $1,200. 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 companies also offer door installations, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, 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, buying certified energy-efficient windows can save Collinsville homeowners $313+ per year after replacing single-pane windows.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the full 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 deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.
