How Installing Energy-Efficient Windows in University City Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Save on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in University City

Each window installation company provides varying services and has varying prices based on several factors.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost depends on several factors, such as size, the location of your home, material, number of windows, type and 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 give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save University City homeowners $376+ per year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of an installation is to figure out whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re not sure which kind of window installation service you need, your installer can assist you. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
