How Installing Energy-Efficient Windows in South River Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in South River

Let’s take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, homeowners in South River can anticipate that most window installations will range from $250 to $1,200, with the average cost at about $600. But prices vary remarkably 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 provide door replacements, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save South River homeowners $306+ each year after replacing single-pane windows.

Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are generally the least pricey 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?

When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.

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

If you’re still trying to decide which type of installation you need, you can ask your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there’s any damage present.
