How Installing Energy-Efficient Windows in Norwalk Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $509 annually on your energy bills in Norwalk.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Norwalk, that’s about 117 pounds per year on average.

Estimated Cost of Window Replacement in Norwalk

Windows come in various shapes, purposes and styles, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Typically, Norwalk homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Norwalk homeowners $509+ per year after replacing single-pane windows.

Something else that influences the total cost is the material you select for your frame. Aluminum frames are generally 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 provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. Because these installations are more involved, they will raise the total cost. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which kind of installation you need, you can consult with your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.
